Achieving Sustainable Freshwater Systems: A Web of Connections | The question being asked around the globe is ?how to satisfy the water demands of an everexpanding human population while at the same time protecting the aquatic ecosystems and ecological services upon which all life depends? (p. 1). Achieving Sustainable Freshwater Systems addresses this question with the purpose of encouraging an integrated, cooperative and adaptive approach to sustaining wetlands and water resources. |
Kinetic studies with synthetic myosin minifilaments show the equivalence of actomyosin and acto-HMM ATPases. | Abstract The kinetic properties of actomyosin have been examined using complexes of actin with the recently described (Reisler, E., Smith, C., and Seegan, G. (1980) J. Mol. Biol., in press) short, bipolar synthetic myosin filaments (minifilaments). It is shown, in contrast to previous observations with aggregated and insoluble myosin, that the kinetic behavior of actomyosin is similar to that of acto-heavy meromyosin. Owing to their size, solubility, and stability under conditions of the actin-activated ATPase measurements, the minifilaments provide a well defined experimental system. Thus, they constitute a convenient and appropriate material for studying actomyosin interactions. |
Observations on the Russian Language in the Modern World | Oddly enough, the position of Russian among the languages of the world has begun to attract the special attention of scholars only very recently. Formerly there were only individual scholars, primarily Academician M. P. Alekseev, who, carefully and successfully studied (and who continues to do so) this question, which is quite important in many respects. (1) A great deal more analysis was done on another problem, albeit one intimately associated with language — the influence of various major Russian writers on world literature and on literary trends in various countries. Research on Turgenev and Dostoevsky, Leo Tolstoy and Gorky, Chekhov and Sholokhov, and other writers developed along these lines. |
Thermal Diffusion in Some Mixtures of Inert Gases | Thermal diffusion has been investigated experimentally in several binary mixtures of inert gases, especially at low ``reduced'' temperatures, and the results compared with theoretical values based on the Lennard‐Jones and exponential‐six molecular models. The thermal diffusion factor for krypton‐argon mixtures is found to pass through a positive minimum value; this behavior, theoretically possible, has not previously been observed. Other mixtures examined are xenon‐krypton and krypton‐nitrogen; the mixtures of radon with neon, argon, and krypton; and the isotopic mixture 22Ne−20Ne. |
ANIMAL SPECIES DEPENDENT LIPOSOME CLEARANCE | Liposomes, upon entering the blood circulation, tend to be rapidly removed from blood by the reticuloendothelial system, mainly the macrophages of the liver and spleen. Concerning liposome uptake by the liver, two different mechanisms are found, one involves serum opsonin and the other does not. For serum dependent clearance, the complement components such as C3 are likely to serve as the opsonins. It is the opsonization process that determines the rate of liposome clearance. For serum independent mechanism, however, the affinity of membrane receptors of the liver macrophages for the head group of lipids in liposomes appears to be dominant factor. More importantly, it is evident that liposome clearance and their underlying mechanisms are animal species dependent. |
Off-line handwritten amount in words recognition using classifiers combination method based on HMM | A new combination scheme was proposed.First,three individual classifiers were constructed with normalized wavelet,stroke density and the percentage of the number of black pixels.Then the combination based on different methods was studied.The experiment results show that the proposed approach can achieve high performance. |
Automatic wave-equation migration velocity inversion using multiobjective evolutionary algorithms | To solve nonlinear seismic velocity inversion problems, we have developed an automatic velocity-estimation technique based on the stochastic method called multiobjective evolutionary algorithms (MOEA). Semblance and differential semblance are used as objective functions. To cope with the high computational cost, we customized MOEA, added domain knowledge (velocity increases with depth, slowly varies along layers, and so forth), which improves the conditioning of the problem and accelerates convergence. This approach is robust because it can cope with large velocity errors. Computational cost of this algorithm is at least two orders of magnitude faster than other stochastic methods and comparable to that of direct gradient methods. |
G-links invariants, Markov traces and the semi-cyclic Uqsl2-modules | Kashaev and Reshetikhin proposed a generalization of the Reshetikhin-Turaev link invariant construction to tangles with a flat connection in a principal G-bundle over the complement of the tangle. The purpose of this paper is to adapt and renormalize their construction to define invariants of G-links using the semi-cyclic representations of the non-restricted quantum group associated to sl2, defined by De Concini and Kac. Our construction uses a modified Markov trace. In our main example, the semi-cyclic invariants are a natural extension of the generalized Alexander polynomial invariants defined by Akutsu, Deguchi, and Ohtsuki. Surprisingly, direct computations suggest that these invariants are actually equal. |
Circumstellar Environments of MYSOs Revealed by IFU Spectroscopy | Formation of massive stars ( M > 8 M ⊙ ) is still not well understood and lacks of observational constraints. We observed 7 MYSO candidates using the NIFS spectrometer at Gemini North Telescope to study the accretion process at high angular resolution (~ 50 mas) and very closer to the central star. Preliminary results for 2 sources have revealed circumstellar structures traced by Brackett-Gamma, CO lines and extended H 2 emission. Both sources present kinematics in the CO absorption lines, suggesting rotating structures. The next step will derive the central mass of each source by applying a keplerian model for these CO features. |
Packaging structure of contact type sensor and its manufacturing method | The present invention relates to a touch sensor package structure, which mainly comprises a substrate, a sensor chip, a conductive member and at least one colloid coating the sensor chip and the conductive member, the substrate having a ground terminal, wherein the conductive member It is electrically connected to the ground terminal of the substrate, a part of the sensing area of the sensor chip and the conductive member is exposed out from the encapsulant to make contact with a user. The present invention further provides a method for manufacturing a touch sensor package structure. |
Observation of two-photon absorption enhancement at double defect modes in one-dimensional photonic crystals | One-dimensional photonic crystals (1D PC) with two CdS defect layers in a SiO2∕TiO2 dielectric thin film stack were fabricated. Two-photon absorption (TPA) coefficients of the CdS defect layers in the 1D PC were investigated using femtosecond pump-probe method. Significant enhancement of the TPA coefficient in the CdS defect layers was observed to occur at the two defect modes. Experimental results show that the enhanced TPA coefficient at the defect mode of 800nm is larger than that at the defect mode of 762nm. A numerical simulation by matrix transfer method is performed and agrees with the experimental results very well. |
Annual Runoff Forecast Method based on Harmonic Analysis | An annual runoff forecast method based on harmonic analysis was investigated and examined using annual runoff data (1956-2007) of Tangnaihai hydrological station in the upper reaches of the Yellow River.Annual runoff could be perfectly modeled by harmonic waves.For forecast term of 2-3 years,harmonic analysis method may give very good forecast of annual runoff,but for longer forecast term,it cannot give accurate prediction. |
Research on Degumming and Fixing Sericin to Obtain Sericin-fixed Souple Silk Yarns without Formaldehyde | In order to obtain sericin-fixed souple silk yarns, various conditions of degumming and fixing sericin were investigated. When raw silk yarns were degummed with solutions of soap and sodium carbonate and then fixed with sericin-fixing agents, degumming losses of 6-17% were attained. The degumming losses attained by degumming and fixing simultaneously in a solution of soap and sodium carbonate containing sericin-fixing agents were in the range of 6-9 percent. By one-step degumming with detergent after fixing sericin, sericin-fixed souple silk yarns were also obtained. In the case of two-step degumming successively twice at 60°C for 30 minutes and at 80°C for 30 minutes with detergent after fixing sericin at 60-80°C for 15 minutes with melamine and formaldehyde, the degumming losses were in the range of 7-13% and sericin removal was uniform. Two-step degumming was very effective for the elimination of free formaldehyde from silk yarns fixed with melamine and formaldehyde. |
Proton pump inhibitors do not accelerate the development of gastric atrophy in Helicobacter pylori gastritis | Kuipers and colleagues1 suggested in 1996 that long-term acid suppression by omeprazole accelerates the development of atrophic gastritis in patients infected with Helicobacter pylori. This, in turn, may facilitate the development of intestinal metaplasia, dysplasia, and gastric adenocarcinoma. This report received widespread media attention because of the public perception, particularly in the United States, that the increasing use of proton pump inhibitors (PPIs), already suspected to be carcinogenic, would cause even more cancer, given the ubiquity of H. pylori infection and gastro-oesophageal reflux disease (GERD) in the general population. The Food and Drug Administration (FDA) convened an urgent meeting to determine if PPIs should be removed from the market or have substantial changes in approved indications and directions for use. |
Amplification Mechanisms in Platelet Activation | Platelets, as they contribute to the formation of an hemostatic plug or an arterial thrombus, are exposed to a multitude of agonists, acting with different strength in concert on the same target cells to amplify each other effects. Such amplification, rather then the potency of the agonists singly, determines the true impact of a so-called weak agonist as serotonin on platelet reactions in pathology. |
Transitory alexia without agraphia in an HIV-positive patient suffering from toxoplasma encephalitis: a case report. | An HIV-positive patient presented the classical syndrome of pure alexia. Neuroradiologic investigation by computed tomography showed a ring-like lesion in the left posterior white matter. The clinical manifestations as well as the radiologic findings resolved after antiprotozoal treatment. |
Regeneration following spinal cord injury, from experimental models to humans: where are we? | Regeneration in the adult CNS following injury is extremely limited. Traumatic spinal cord injury causes a permanent neurological deficit followed by a very limited recovery due to failed regeneration attempts. In fact, it is now clear that the spinal cord intrinsically has the potential to regenerate, but cellular loss and the presence of an inhibitory environment strongly limit tissue regeneration and functional recovery. The molecular mechanisms responsible for failed regeneration are starting to be unveiled. This gain in knowledge led to the design of therapeutic strategies aimed to limit the tissue scar, to enhance the proregeneration versus the inhibitory environment, and to replace tissue loss, including the use of stem cells. They have been very successful in several animal models, although results are still controversial in humans. Nonetheless, novel experimental approaches hold great promise for use in humans. |
Slow and steadywins the race? energy consumption analysis of an EV competition | Electric vehicle competitions have been organized in order to test the limits of technology. In this paper, we describe a competition for students and the public. The competition was held in Lappeenranta in 2013. We also analyze what kinds of vehicles were used and what the winning strategy was. |
Iodine-Catalyzed Aza-Diels–Alder Reactions of Aliphatic N-Arylaldimines | Abstract Iodine-catalyzed aza-Diels–Alder (Povarov) reaction of 3,4-dihydro-2H-pyran with in situ generated N-arylimines containing enolizable protons is described. This has given an easy way to introduce C-2 aliphatic substitution in tetrahydroquinolines. |
Substituted 6-Phenylnikotinsäuren and their use | The present application relates to novel substituted 6-Phenylnikotinsaure derivatives, processes for their preparation, their use for the treatment and / or prophylaxis of diseases and their use for producing medicaments for the treatment and / or prophylaxis of diseases, preferably for the treatment and / or prophylaxis cardiovascular disorders, especially of dyslipidemias, atherosclerosis and heart failure. |
Effect of Permeability on Surficial Stability of Homogeneous Slopes | In Southern California the conventional method for evaluating surficial stability has a bias towards cohesion. It suggests that surficial failures are more likely in slopes made of sandy and gravelly soils, than those composed of clays and silts. This contradicts actual observations. A study of the equations governing seepage and rainfall data in Southern California suggests that permeability plays an important role in the surficial stability of slopes. In homogeneous slopes this study finds that soils with a low permeability are more prone to develop the conditions leading to a surficial failure mechanism. Hence, clayey and silty soils slopes are more prone to develop surficial instability than slopes made of sandy or gravelly soils. This study also finds that soils with a permeability greater than a certain limiting value, klim, will not become saturated. It is found that the Unified Soil Classification System is useful in evaluating the likelihood that a surficial failure mechanism with seepage paralle... |
MRI and pathological changes in the brain of patients with chronic liver dysfunction | Three patients with chronic liver dysfunction underwent cerebral magnetic resonance imaging and pathological studies of the brain at autopsy. All showed high-signal basal ganglia on T1-weighted images. Proliferation of astrocytes in the globus pallidus was observed in only one of the three brains. Increased amounts of paramagnetic trace metals (Fe, Mn, Zn, and Cu) were detected in the globus pallidus of two brains, but there was no increase in the third brain. These results suggest that an MR signal change in a patient with chronic liver dysfunction does not directly reflect astrocyte proliferation or deposition of paramagnetic trace metals. |

Clinical examination of nitroglycerin spray (EGIS) in angina pectoris patients. | On the basis of our examinations it may be stated that the new product of EGIS Pharmaceuticals Nitromint aerosol seems to be effective and well tolerable in the course of clinical examinations. The drug action develops significantly more rapidly as compared to Nitromint tablet. Significant difference was not found when comparing the duration of action of the two products. The adverse effects are the same as the undesired effects of other short-acting nitrate preparations. Mostly local unwanted effects were observed. It can be recommended in all forms of angina pectoris for controlling pain syndrome and in effort angina for prophylactic purposes. In acute left heart failure it may be used in urgent cases. Because of its effectiveness and easy applicability the patients prefer Nitromint aerosol to Nitromint tablet. |
Differential effects of exposure to ambient vanilla and citrus aromas on mood, arousal and food choice | Background ::: Aromas have been associated with physiological, psychological affective and behavioral effects. We tested whether effects of low-level exposure to two ambient food-related aromas (citrus and vanilla) could be measured with small numbers of subjects, low-cost physiological sensors and semi-real life settings. Tests included physiological (heart rate, physical activity and response times), psychological (emotions and mood) and behavioral (food choice) measures in a semi-real life environment for 22 participants. |

Self-Powered Cardiac Pacemaker Enabled by Flexible Single Crystalline PMN-PT Piezoelectric Energy Harvester | A flexible single-crystalline PMN-PT piezoelectric energy harvester is demonstrated to achieve a self-powered artificial cardiac pacemaker. The energy-harvesting device generates a short-circuit current of 0.223 mA and an open-circuit voltage of 8.2 V, which are enough not only to meet the standard for charging commercial batteries but also for stimulating the heart without an external power source. |
Benzethonium chloride assay——A new method for the determination of proteins in cerebrospinal fluid | Objective To evaluate the benzethonium chloride method for determination of proteins in cerebrospinal fluid.Methods The protein in cerebrospinal fluid was determined by turbidimetry using Roche benzethonium chloride reagent and observation of the precision,sensitivity and detection limits of the method. Results The within-run coefficient of variation(CV) of method were 1.5%,2.3% and the between-run CV were 0.62%,0.72%.The sensitivity of method was 0.08 g/L.The detection limit was 1.9 g/L.The regression equation between new method and routine sulfosalicylic acid(SSA) method was Y=0.854 X+0.097,r=0.985.Conclusions This method is simple,fast,accurate,with minimal sample volume(9~15 μL),and suitable for clinical laboratory. |
Regularization of the two body problem with variable mass | Using Levi Civita's regularization, we put the two body problem with variable mass (x=−Mxr−3) into a form which can be solved analytically on computer. Two particular cases are discussed: 1.\(\dot M\)=C te ; 2.\(\dot M\)÷Mα (α unspecified). |
Simulation of power losses with MATLAB/Simulink using advanced power device models | This paper proposes a simulation concept to determine the power losses of high-power converters using the simulation tool MATLAB/Simulink. A new behavior model which describes the dynamic switching behavior of high-power devices is developed and implemented. As an example, a detailed analysis of the power losses of the auxiliary resonant commutated pole inverter (ARCP) is shown. |
Data Type Integration for Protein Identification using Kernel Based Classification Methods | The integrated biological data is expected to obtain a higher exactness, better performance and greater robustness compared to single dataset. In this work, we present data integration using kernel-based approach to identify protein class in yeast, ribosomal proteins and membrane proteins. By using intermediate stage of integration, we change the single data source into kernel matrix format. Kernel weighting was used in the establishment of integrated data. We propose three weighting methods approach i.e. KTA (Kernel Target Alignment), FSM (Feature Space-based kernel matrix evaluation Measure), and AI (Alignment Index). We also perform the combination of these three methods. These integrated kernels will be analyzed using Support Vector Machine (SVM). Our proposed data integration methods achieve a higher performance compared to single data source. KTA is the best kernel weighting measurement method and always obtain a better performance to recognize membrane and ribosomal proteins classes than others. |
Destrucción - deconstrucción en diseño | Tour across the modernity in three matters: Design, art and architecture to demonstrate as the deconstruction you ma of which he is an author (Jackes Rerrida) is applied of the Industrial Design leaving to the overdraft the transformation of the object of the contemporaneousness in the current thing. Deconstruction of the Industrial Design, where the ephemeral thing prevails, the event and the experience and the garbage understanding the latter as that waste that fulfill the three (you) (are) recyclable, reusable and to reduce. |
New Technology For Beryllium Mirror Production | Current methods for fabricating beryllium optics are both time consuming and too expensive for many production applications. This has sometimes resulted in the substitution of marginally acceptable materials which do not always deliver the required performance. The advent of net shape blank fabrication directly from powder, utilizing disposable tooling and the hot isostatic pressing process, has provided the breakthrough which enables the cost effective production of beryllium mirrors. |
Ocular Chemical burns in the dermatology office: a practical approach to managing safety precautions. | Chemical burns to the eyes are one of the few ocular emergencies that dermatologists may encounter in their everyday clinic. As such, dermatologists should be confident in their ability to urgently manage ocular chemical injuries should accidental exposure occur during a procedure. We report a case of accidental ocular exposure to aluminum chloride hexahydrate during skin biopsy of the cheek and subsequent transient ocular injury that resolved with early appropriate management. This article provides background information on acute chemical ocular injuries, offers practical step-by-step guidance for the dermatologist, and highlights immediate copious irrigation as perhaps the most critical step in determining the clinical course of the injury. |
Laser Initiated Free Radical Chemistry | The topic which will be covered in the series will be that of the use of lasers in free radical processes. The object of our work is to either develop novel processes based on laser initiated free-radical reactions or optimize the present reactions. Many industrial chemicals are currently produced via organic photochemistry including commodity chemicals such as caprolactam and methyl-chloroform. There also have been recent reports1 of a potential photochemical pathway for the production of vinylchloride which is another large volume material. |
Diffusion of a strong magnetic field in a dense plasma | The authors consider the plane diffusion of a transverse magnetic field from a vacuum into a dense plasma in the collisional regime. A magnetic pinch discharge on the surface of an insulator can be considered as a special case of diffusion in a plasma of infinite density. The authors consider strong magnetic fields such that the plasma can be assumed to be completely ionized. The diffusion of a magnetic field in a hydrogen plasma at small values of the time is discussed. |

[New concepts on the pathogenesis of chronic Chagas cardiomyopathy: myocardial gene and protein expression profiles]. | The pathogenesis of chronic Chagas cardiomyopathy (CCC) is still being unraveled. In the last decade, a role for inflammatory cytokines on tissue damage has been shown. The present review will address the molecular and immunological mechanisms of tissue damage on human CCC with a special focus on results obtained by our research group using genomic and proteomic approaches. The results suggest that direct modulation of myocardium gene and protein expression by inflammatory cytokines may be a new pathogenic mechanism in CCC, with therapeutic implications. |
Haar-Type Orthonormal Wavelet Bases in R² | K.-H. Grochenig and A. Haas asked whether for every expanding integer matrix A ∈ Mn(ℤ) there is a Haar type orthonormal wavelet basis having dilation factor A and translation lattice ℤn. They proved that this is the case when the dimension n = 1. This article shows that this is also the case when the dimension n = 2. |
[Chemical modification of epsilon-NH2 groups of lysine residues in horseradish peroxidase. Accessibility of these groups to different modifying agents]. | Modification of epsilon-NH2 groups of lysine residues in horseradish peroxidase by acetic, propionic, butyric, valeric and succinic anhydrides and trinitrobenzenesulfonic acid (TNBS) is carried out. All the anhydrides modify at 0 degrees C four epsilon-NH2 lysine groups, and TNBS--three groups. TNBS modifies all 6 peroxidase epsilon-NH2 groups at 40 degrees C. Possible spacing of lysine epsilon-NH2 groups in the enzyme molecule is discussed. |
The perception of voice pitch by naïve and experienced listeners | Perceptual judgments of a single speaker’s voice pitch will be characterized by any given listener along a subjective continuum. Individual listener attributes have been suggested as an explanation for this diversity in categorizing voice pitch. Professionals involved in the evaluation of voice, specifically voice pitch, are expected to possess a level of perceptual skill that reliably quantifies pitch regardless of personal attributes. Two groups of individuals, one naive and one experienced, were asked to perceptually match voice pitch during two pitch matching tasks. The first task involved matching an audio taped voice pitch produced on the vowel /a/ to a musical note on a keyboard. The second task involved listening to an audio‐taped voice producing words, then matching the voice pitch of the word to a musical note on a keyboard. Accuracy of perceptual judgments was measured upon stimuli produced and assigned musical keyboard note by master’s level opera music majors. Results indicate that a differen... |
Ion-Induced Random Electric Fields in Aqueous Salt Solutions as Studied by the Four-Photon Polarization Spectroscopy Method | Using the four-photon polarization spectroscopy we have studied the Rayleigh wing spectral patterns of several aqueous salt solutions within the 0-50 cm-1 frequency range. Within the framework of an approach allowing a representation of the Rayleigh wing spectrum as two Lorentzian functions, characterized by the long and the short times of relaxation of an anisotropic mode, we obtained that the short relaxation time does depend on the concentration of electrolyte and its type, whereas the long relaxation time does not. The effect can be qualitatively interpreted supposing that the fluctuations of ionic concentration give rise to the fluctuations of local electric field. An instantaneous magnitude of this field is about 104 V/cm and its time of changing is about 10-12 s. This electric field initiates local microscale Kerr-effects thus contributing to the fluctuations of optical anisotropy, which accounts for an additional depolarized scattering. |
Successful percutaneous closure of coronary artery fistula with angiographic follow-up at 6 months. | Congenital coronary artery fistula can present later in life. We describe a case in a 56 year old, who was managed percutaneously with coil embolization leading to complete closure of the fistula, which was confirmed by follow-up angiography at 6 months. © 2008 Wiley-Liss, Inc. |
Structure of e{sup +}e{sup {minus}} {r_arrow}b anti-b Events and Improved Limits on the Anomalous Chromomagnetic Coupling of the b-quark | The structure of e{sup +}e{sup {minus}} --> b anti-b g events was studied using Z{sup 0} decays recorded in the SLD experiment at SLAC. Three-jet final states were selected and the CCD-based vertex detector was used to identify two of the jets as b or anti-b. Distributions of the gluon energy and polar angle were measured over the full kinematic range, and compared with perturbative QCD predictions. The energy distribution is potentially sensitive to an anomalous b chromomagnetic moment kappa. The authors measured kappa to be consistent with zero and set limits on its value, {minus}0.11 < kappa < 0.08 at 95% c.l. (preliminary). |

Topic discrimination using higher-order statistical models of spotted keywords | Abstract Keywords that are characteristic of a topic are ranked by a criterion of usefulness, and a relatively small number (typically 10) of the best keywords are implemented in a hidden Markov model (HMM)-based word-spotting algorithm. Statistical models of counts of occurrences of keywords are used to discriminate topic from non-topic speech. In the simplest model, distinct keywords are treated as independent. Particular combinations of keywords can often improve discrimination, however, and linear-logistic and log-linear models enable higher-order dependencies of the topic on keywords to be detected, leading to enhanced performance. Models involving a small number of parameters can be estimated from modest amounts of training data. Heuristic procedures point the way to good models but assume statistical consistency between training and test data. The approach is tested using a broadcast radio database. |
A Monograph on Recurrence Relations | The main objective of bringing out this monograph is, unlike so many others, is the passion towards the subject by name mathematics. While being passionate for this subject, I thought of making my passion should be useful to, at least some people who are crazy about mathematics just like me. This monograph gives and emphasis on recurrence relations and it is tag lined as Methods to Madness, not to make a people mad but to prove that it can make you fall in love with mathematics madly. A large number of problems have been discussed and the solutions are presented in a way that they can be of great help to researchers. What is more important is that all these problems are very much useful for researchers and scholars as they are solved in a very lucid and comprehensive manner. We are hopefully the solutions will help you for your endeavors, since new techniques and methods are adopted for bringing out the solutions. |
Quasi-isotropic analysis of anisotropic thin films on optical waveguides. | Thin films assembled on a substrate are often anisotropic. Nevertheless, because of experimental limitations, sufficient parameters to characterize the anisotropy, even in the simplest (and perhaps most common) case of uniaxial thin films, which are birefringent, are not usually available. This paper examines the consequences of treating them as isotropic thin films, with particular reference to their characterization via perturbation of the propagation constants (effective refractive indices) of optical waveguides. It is shown that the refractive index and geometrical thickness of a thin film thus calculated are often unrealistic (especially when the thin film is positively birefringent), but the mass per unit area may be quite precise, depending on the sign and magnitude of the birefringence. |
Factors Associated with Use of Short-Term Pre-Exposure Prophylaxis for HIV Among Female Partners of Migrant Miners in Mozambique | Abstract Effective interventions tailored to specific types of behaviors and contexts are needed for women at risk for HIV acquisition. Oral pre-exposure prophylaxis (PrEP) is an efficacious HIV prevention intervention that uses antiretroviral drugs to reduce the risk of acquiring HIV infection. In Mozambique, HIV remains a major public health concern, with a national prevalence of 13%. Studies have demonstrated that the migration of male miners between southern provinces of Mozambique and South Africa is contributing to the HIV epidemic in Mozambique. This increased risk is associated with the engagement of male miners, while separated from their partners, in sexual relationships with other women, including transactional sex workers, in a hyperendemic setting in South Africa. We conducted 25 in-depth interviews with a subset of female partners in a stable relationship with migrant miners participating in a prospective cohort study to assess the feasibility, acceptability, and adherence to daily oral shor... |
Los diálogos interestróficos en el Cancionero de Palacio (SA7) | Traditionally it has been considered that Castilian cancionero poetry has hardly preserved dialogos interestroficos, such as the primitive tenson. However, the Cancionero de Palacio contains a very significant sample of the different possibilities of the cancioneril dialogic mold: beyond poetic dialogue forms more common in Fifteenth Century Spanish poetry, through whole texts juxtaposed, the Cancionero de Palacio contains several other more original forms, and as a result it serves as a codex unicus. This article offers, for the first time, an analysis of all the dialogos interestroficos collected in this Cancionero. This analysis contradicts the widely held view about the rarity and scarcity of these texts and confirms the originality of the dialogic schemes and the strong presence of polyphonic texts in this colectanea. The article presents a list of twelve compositions—a very significant number—in which the dialogue articulates all the text, with voices alternating stanza to stanza or even within each... |
Complex Networks Theory and Its Application in Study of Traditional Chinese Medicine | Traditional Chinese Medicine (TCM) is the systemic medicine which holds on integral rules on diseases’ changing. In this paper,we briefly reviewed the statistical properties structure model,the topologies model and the basic analytical methods in complex networks. We put forward an idea to demonstrate complex systems of TCM,such as TCM syndrome in hepatitis B network,using the complex networks theory and method. We found that there is a small-world characteristic in TCM syndromes in hepatitis B network. It was suggested that there is the characteristics of TCM syndrome classification in patients with hepatitis B. It may provide a useful method for the research of TCM complex system and the clinical diagnosis of TCM. |
Living ‘in between’ outside and inside: The forensic psychiatric unit as an impermanent assemblage | This paper presents analysis from a study of staff and patient experiences of the restrictive environments of a forensic psychiatric unit. The paper conceptualises the forensic unit as an impermanent assemblage, enacted in and through practices that hold a future life outside the unit simultaneously near, yet far. We show how the near-far relations between life inside and outside the unit operate in three ways; 1) in relation to the ‘care pathway’, 2) practices of dwelling, and 3) creating and maintaining connections to life ‘beyond’ the unit. The paper concludes with a discussion about possible ways to overcome the limitations to recovery that can arise through practices of impermanence. |
Determination of axial dispersion and overall mass transfer coefficients for Ni (II) adsorption on nanostructured γ-alumina in a fixed bed column: experimental and modeling studies | AbstractIn this study, nanostructured γ-alumina is used as an adsorbent for the removal of nickel from aqueous solutions using a fixed-bed column and batch experiments. Different parameters, including the initial nickel solution concentration, contact time, and pH were analyzed to determine their optimum values. The results showed that adsorption efficiency increased as contact time increased; optimum contact time was observed to be 150 min. The efficiency of removing metal ions from an aqueous solution increased as pH increased from 2.5 to 4.5, but decreased as pH rose higher, thus, optimum pH was determined to be 4.5. The Langmuir isotherm model showed better agreement with the experimental data than the Freundlich and Tempkin isotherm models. The maximum capacity of the adsorbent in the Langmuir equation was 78.74 mg/g. In the present study, adsorbent bed performance breakthrough curves for different adsorbent bed heights, influent flow rates, and concentrations were analyzed. The experimental data sho... |
Propagation Experiments of Cutting Chamaecyparis thyoides′s Three Forms | Chamaecyparis thyoides was introduced and cultivated in China more than 60 years ago.Three forms of differentiation have showed on the plant,that is,narrow crown form,broad crown form and dwarfish form.The cutting experiments of Chamaecyparis thyoides were made with the branches of these 3 forms,inspectively.A variance analysis is made on the data from the experiments with LSD inspection to compare their growth states.The results show that there are significent differences in survival percent,growth rate and other respects of chamaecyparis thyoides′s 3 forms. |
Microsecond switching of parametric tunable dispersion compensator. | A record-fast, 2 μs switching operation of an optical tunable dispersion compensator is demonstrated with a parametric tunable dispersion compensation scheme. We alternately switch two optical paths having different net dispersions with a microsecond guard interval of the compensator response and achieve successful transmissions of 43 Gbit/s non-return-to-zero on-off-keying optical signals. The error-free guard time for the switching of the two optical paths is 125 μs, limited mostly by the clock synchronization of the bit-error detector. The power penalty due to the switching of the compensator is less than 0.5 dB. |
Simulation and Comparison of Two Different Pedestrian Bridges in Vibration Performance Under Crowd Load | To verify whether the pedestrian bridge with steel beams have better vibration performance under crowd load in replacing the steel beams with concrete-filled rectangular steel tube beams,this paper chose a simply supported pedestrian bridge with single span which was built with H-Section Steel Beams and reinforced concrete slabs.Then the H-Section Steel Beams was changed into concrete-filled rectangular steel tube beams based on equivalent stiffness principle.The two bridges were modeled by ANSYS and brought to make time-history analysis under crowd load.Their vibration performances were compared with maximum and mean square root acceleration.The results show that the pedestrian bridge with concrete-filled rectangular steel tube beams has much lower acceleration maximum and mean square root than that with steel beams,which verifies the pedestrian bridge with concrete-filled rectangular steel tube beams has better vibration performance under crowd load than that with steel beams. |
Oxidative Rearrangement of Tertiary Allylic Alcohols | A general synthesis of -unsaturated carbonyl compounds has been developed by oxidation of t-allylic alcohols. In simpler system, pyridinium chlorochromate oxidation affords the functionality transposed carbonyls in excellent yields, making the reaction a useful and versatile synthetic method |
MR recognition of supratentorial tumors. | Eighty patients with intrinsic tumors of the cerebral hemispheres and thalami were studied with a 0.5 T superconducting system and third- or fourth-generation computed tomographic (CT) scanners. Twenty-eight patients had histologically verified gliomas, 34 were presumed to have primary brain tumors on clinical grounds, 13 had metastases, and five were postoperative. Lesions shown on CT were equally well demonstrated on magnetic resonance (MR) imaging; more metastases were seen on MR than on CT images. MR revealed abnormal signals in 10 cases in which CT findings were equivocal. It was not possible to differentiate edema from tumor in many cases using the MR imaging sequences currently available. The histologic types of the tumors could not be determined from the MR appearances. |
Oxidative reactions of tetrahydrobenzimidazole derivatives with N-sulfonyloxaziridines | An investigation of the utility of N-sulfonyloxaziridines to effect the oxidative rearrangement of tetrahydrobenzimidazoles to spiro fused 5-imidazolones is reported. In addition to the anticipated rearrangement manifold, it was found that 2-amino substituted derivatives afford products resulting from rearrangement, or alternatively from addition of methanol or water depending on the nature of the N-substituents and reaction conditions. |
An Entropy Model of Information Quality Verification | This paper used entropy theory to reach a conclusion that under the condition of enough large samples, the average empirical information amount is approximate normal distribution; using this conclusion, the authors presented a method to test the quality of information, and analyzed the credibility of prior and posterior information. As a result, it can improve the capability of decision makers to select right information. |
Accelerating Particles with Plasma | Researchers at SLAC explain how they use plasma wakefields to accelerate bunches of electrons to very high energies over only a short distance. Their experiments offer a possible path for the future of particle accelerators. |
Is slow what the slow university's about | This is the first of a trio of posts about the Slow University that started life as presentations in a seminar at the Institute for Advanced Studies in Durham University. In it, guest blogger Luke Martell, argues that we shouldn’t fetishise speed at the fast university. This distracts from what’s behind it. And we should ask whether slow is what the slow university’s really about. |
Some Types of Ambiguities in the Sagas of the Icelanders | It seems reasonable to expect that everyone would instantly recognize Skarpheðinn Njalsson w ithout ever having laid eyes upon him .1 He is, after all, a celebrated saga-hero; not only on account of his extraordinary feats in battle — most prom inent among these the famous “skating to kill” scene — but distinguished also by his battle-axe, his grin and numerous memorable one-liners. In fact, Njals saga prepares its audi ence for an extraordinary character from the outset, in Skarpheðinn's introduction in chapter 25: |
Urinary urge seizure semiology localization by intracranial monitoring. | Seizures may present with many different symptom complexes. Seizure semiologies have localization value when contemplating surgical therapies. Epilepsy presenting as a desire to micturate is exceedingly rare, with only a handful of published cases. We present a patient who had initially unexplained childhood urinary urge that progressed into lapses of memory and confusion that was eventually diagnosed as epilepsy in adulthood. Due to refractoriness to medical management, our patient's epileptic focus was localized through both noninvasive and invasive subdural electrode arrays to the nondominant medial temporal lobe and successfully treated with an amygdalohippocampectomy. Only one other case of ictal urinary urgency seizures has been recorded with intracranial electroencephalogram monitoring in the literature. |
LABORATORY STUDY OF THE MECHANICAL CHARACTERISTICS OF BITUMINOUS MIXTURES | This article presents results of laboratory tests recently conducted at the LCPC. Part 1 analyzes the main results of complex modulus and fatigue tests obtained on the main types of bituminous mixture, on mixtures containing modified binders and on mixtures to which industrial waste products had been added. The influence of the temperature and the role of compaction are stressed. A review is presented of the practical means known at the present time of improving the mechanical characteristics vis a vis those 2 parameters. Part 2 outlines a direct tensile test recently developed at the LCPC where an attempt was made to reproduce in the laboratory stress similar to the real extension occurring in the lower part of a flexible pavement. The various phases of the test can be carried out on the same sample and supply results on modulus values, loss of linearity and failure characteristics. (TRRL) |
Do students cheat-or are they just good guessers? | An experiment designed to see if students would, if given the opportunity, cheat, revealed that whilst a small minority might, alterations of answers from wrong to right occurred more frequently than the reverse. This would seem to suggest that students are good guessers and examination design should perhaps allow for this. |
Reduction of Truncation Error in Computing Symplectic State Transition Matrix | This paper describes a high precision computation method of deriving general symplectic state transition matrices. Respecting the symplectic structure of state transition matrices is important in such a field as accurate, yet computationally efficient dynamic filters, longterm propagations of the motions of formation flying spacecraft and the eigenstructure/manifold analysis of N-body dynamics etc. The method proposed in this paper is a post-processing to improve or add a symplectic property to arbitrary state transition matrices. Since this method can be combined with any state transition matrix derivation schemes, it works as a truncation error reduction and also provides a simple way to add the symplectic property to matrices derived with non-symplectic methods. We present the derivation, its applicability and numerical evaluations when applied to a twobody dynamics, an Earth orbit with perturbation forces based on the real ephemeris and a circular restricted three-body problem. |
Optimizing a System of Threshold-based Sensors with Application to Biosurveillance | Joint session of the 2008 Qualitative Methods in Defense and National Security conference and the closing workshop for the SAMSI Program on Risk Analysis, May 2008. |
Security improvement on Yang-Shieh's authentication scheme | Yang and Shieh (1999) proposed a timestamp-based password authentication scheme using smart cards. However, Chan et al. (2002) and Fan et al. (2002) showed its vulnerability to the forged login attacks, respectively. Also Fan gave a slight modification of the original scheme, which however increases the computation cost of the system. In this paper a more efficient modification of the original scheme is proposed to withstand the forged login attacks. |
[Production of low-caloric stewed fruits with the use of natural sweeteners]. | Specifications, operation conditions and formulas of preparation of natural dietetic stewed fruits were developed. The best large- and small fruit cultivars with maximum displaying of biochemical indexes were recommended for development of specimens; in addition to it flexible regimes of heating were used. |
[Temporomandibular joint (TMJ): Condyle hyperplasia and condylectomy]. | The mandibular condyle is a special structure. Its embryology and physiology provide to the TMJ a particular behavior that explains the occurrence of specific diseases. Condyle hyperplasia is one of these disorders. It can be explained by a dysregulation of the prechondroblast cell layer within the cartilage cap providing an increase in volume first of the condyle, then of the ramus and finally of the entire affected hemiface. Mandible deformation affects the basal bone, leading to dento-alveolar deformations related to compensation attempts. Controversies, condylectomy is performed by many surgeons. This procedure allows for the correction of some of the dento-alveolar compensations. In some cases, an additional orthognathic surgery will be required to achieve a perfect result. |
Post-suxamethonium pains in Nigerian surgical patients. | Contrary to an earlier report by Coxon, scoline pain occurs in African negroes. Its incidence was determined in a prospective study involving a total of 100 Nigerian patients (50 out-patients and 50 in-patients). About 62% of the out-patients developed scoline pain as compared with about 26% among the in-patients. The abolition of muscle fasciculations (by 0.075mg/kg dose of Fazadinium) did not influence the occurrence of scoline pain. Neither the type of induction agent (Althesin or Thiopentone) nor the salt preparation of suxamethonium used (chloride or bromide), affected the incidence of scoline pain. |
Spatial soliton optical switches: a soliton-based equivalent particle approach | The spatial soliton plays a fundamental role as a robust, particle-like object which can be manipulated to switch or spatially scan collimated light channels or optical pulses which are incident at an oblique angle to an interface separating two or more selffocusing Kerr slab dielectrics. The underlying equivalent particle/multiparticle theory can also be employed to predict stability properties of nonlinear surface or guided waves, to derive an analytic expression for the nonlinear Goos-Hanchen shift at a nonlinear interface and to quantify the effect of material diffusion, linear and twophoton absorption on the switching behaviour of the light beam. Pulsed spatial switching effects are studied in order to illustrate the general predictive power of the equivalent particle theory. |
Pollen grain morphology ofCoris (Primulaceae) | Pollen grain morphology, sculpturing, and wall ultrastructure are investigated in two species ofCoris (Primulaceae),C. monspeliensis L. andC. hispanicaLange. The study includes both acetolysed and unacetolysed pollen. No evidence of any major palynological difference is recorded between these two species, apart from a somewhat larger pollen inC. monspeliensis. However,Coris can be distinguished from the remaining members of thePrimulaceae by the conjunction of relatively large pollen grains, prominent margo, and particular tectal pattern causing a reticulate surface with minute luminal perforations decreasing towards the colpi. From both these distinctive features, and others typically primulaceous, some evolutionary considerations are inferred. Finally, the higher proportion of irregular grains inC. hispanica is interpreted in light of environmental stress. |
Getting the whole picture: Wide-azimuth multicomponent seismic | Acquiring four-component seismic data with wide-azimuth geometry provides an opportunity to build a very complete seismic picture for reservoir description. The recording of the full vector wavefield allows creation of both PS-wave data as well as P-wave images which contain different but complementary information. It also provides full-azimuth illumination of the subsurface. Azimuthal images improve definition of structural features, such as faults, that may only be illuminated within certain preferential shot-receiver azimuths. Differences in azimuthal images can also be very sensitive fault indicators in the case of small vertical displacements. Furthermore, and of crucial importance at the reservoir scale, wide-azimuth P-wave and PS-wave data lend themselves to the evaluation of azimuthal anisotropy. These attributes provide valuable spatial constraints in the characterization of heterogeneously distributed subseismic scale fractures. |
A personalised access to e-gov services : A user-oriented approach | During the last decade, Morocco has known a great development of e-government (e-gov) services reflected by a significant number of target projects of different types. However, one of the biggest challenges facing Moroccan e-gov is that of ensuring an easy and personalised access to e-gov services. To overcome this problem, we have tried through this work to present a contribution to personalise the access to e-gov services by defining a user profile and its integration into the e-gov services' retrieval process. Accordingly, we have studied the different approaches of the user profile modelling; on the base of which we have adopted the multidimensional representation. This study has enabled us to propose a user profile model. Then we have suggested a new user profile management process to manage the different knowledge related to the user profile. Finally, we have discussed how we integrate the user profile in our services retrieval process to ameliorate the search pertinence. |
CONTRIBUTION OF THE JOMINY-TYPE END QUENCH TO METALLOGRAPHIC PHASE IDENTIFICATION IN URANIUM | The identification of phases and interpretation of phase transformation through microstructural analysis are still difficult even with metallographic standards as a guide. Macrostructures provide a better guide to determination of the origin of the quenched phase and the degree of quenching. Grain sizes are of some assistance in determining the cooling conditions employed. Twinning concentration and grain boundry shape are inconclusive characteristrcs to use in determining the origin of the quenched phase and the degree of quenching. Subgrains are more prevalent in beta-treated uranium. Hardness profiles provide highly irregular data and are of little assistance in interpretation of heat- treating conditions. Single and multiple gamma-beta-alpha cycles appear severe enough to cause the formation of small voids in thc air-cooled zones of end quench samples. (auth) |

Treatment of Anogenital Papillomavirus Infections with an Acyclic Nucleoside Phosphonate Analogue | To the Editor: (S)-1-(3-hydroxy-2-phosphonylmethoxypropyl)cytosine (HPMPC) is an acyclic nucleoside phosphonate analogue with broad-spectrum antiviral activity against DNA viruses, including herpesviruses (herpes simplex virus, varicella–zoster virus, cytomegalovirus, and Epstein–Barr virus), adenoviruses, poxviruses, and papillomaviruses.1,2 We recently showed that local injections of HPMPC into a life-threatening squamous papilloma of the hypopharynx–esophagus eradicated the tumor.2 Two years later, the patient was still free of disease. We report the use of HPMPC in three patients with AIDS and severe, relapsing anogenital human papillomavirus lesions. A 44-year-old homosexual man had been unsuccessfully treated for recurrent penile human papillomavirus lesions since December 1993 with curettage . . . |
H-Ras is degraded by Wnt/β-catenin signaling via β-TrCP-mediated polyubiquitylation | Ras is an important proto-protein that is regulated primarily by GDP/GTP exchange. Here, we report a novel regulatory mechanism whereby turnover of both endogenous and overexpressed H-Ras protein is controlled by β-TrCP-mediated ubiquitylation, proteasomal degradation and the Wnt/β-catenin signaling pathway. The interaction of H-Ras with the WD40 domain of β-TrCP targeted H-Ras for polyubiquitylation and degradation. This process was stimulated by Axin or adenomatous polyposis coli (Apc), and was inhibited by Wnt3a. Ras-mediated cellular transformation was also inhibited by the expression of β-TrCP and/or Axin. In vivo regulation of Ras stability by Wnt/β-catenin signaling was determined via measurements of the status of Ras in the intestines of mice stimulated with recombinant Wnt3a by intravenous tail vein injection. The regulation of Ras stability by Wnt/β-catenin signaling provides a mechanical basis for crosstalk between the Wnt/β-catenin and the Ras-ERK pathways involved in transformation. |
Development and evaluation of immunoassay for zeranol in bovine urine | A high affinity polyclonal antibody-based enzyme linked immunosorbent assay (ELISA) was developed for the quantification of zeranol in bovine urine. On the basis of urine matrix studies, the optimized dilution factors producing insignificant matrix interference were selected as 1:5 in pretreatment. In the improved ELISA, the linear response range was between 0.02 and 1 μg/ml, and the detection limit was 0.02 μg/ml for the assay. The overall recoveries and the coefficients of variation (CVs) were in the range of 82%∼127% and 3.5%∼8.8%, respectively. Thirty-six bovine urine samples spiked with zeranol (ranging from 0.2 to 10 μg/ml) were detected by the ELISA and liquid chromatography (LC) method, and good correlations were obtained between the two methods (R2=0.9643). We conclude that this improved ELISA is suitable tool for a mass zeranol screening and can be an alternative for the conventional LC method for zeranol in bovine urine. |
Pt-Rh-Pd Alloy Group Gauze Catalysts Used for Ammonia Oxidation | Abstract Pt-Rh-Pd alloy gauze catalysts used for ammonia oxidation were studied to improve the efficiency in the industry of nitric acid. According to the character of ammonia oxidation, such catalysts were divided into three main reaction zones. Pt-Rh-Pd alloy group gauzes were installed in dual pressure ammonia oxidation apparatus with the diameter of 3880 mm, which was operated under a pressure of 0.35 MPa. Based on the characterization by FESEM and EDS, the catalysis mechanism of the gauze catalysts was proposed. Through the calculation of oxidation efficiency, the catalysis effect is improved by 1% with the Pt-Rh-Pd alloy gauzes, where the involvement of Pd endows the catalyst with catalysis, catchment, solid solution and second catalysis. As the result, the cost is reduced by 30% and the loss of Pt is decreased from 120 mg to 70 mg. Thus, the catalysts show the great potential for future industrial applications. |
Professional Practice of Counseling Psychology in Various Settings | Counseling psychology has traditionally been associated with particular practice settings. The past 25 years, however, have shown an increase in the diversity of settings in which the counseling psychologists' unique perspective is applicable and valued. This report examines the evolution of counseling psychology's perspective and several arenas in which counseling psychologists currently practice. Implications for our expansion into various settings and for accreditation and practice standards are explored. Recommendations for implementation of suggested changes are presented. |
A model of river bank deformations under the simultaneous effect of waves from a hydropower plant and warming | This paper presents a mathematical model of the river bed deformations in permafrost areas. The deformations are caused by the influence of waves of various origins under an increase of the ambient temperature. The model system consists of an unsteady hydrodynamic module, a thermal module and a bed deformation module. The hydrodynamic module is based on the two-dimensional shallow water equations. The bed deformation module is based on the sediment mass balance conditions. The thermal module is based on the Stefan equation, which defines the "water–ice" boundary movement. We present two applications of the model in which the bed deformation is calculated for the alluvial channels with melting bed under the influences of waves of different duration and intensity. We compared the model predictions with the laboratory data, generally obtaining a good agreement between the two. |
[The value of plasma antiretroviral drug monitoring in the management of HIV infected patients]. | Antiretroviral drugs exhibit significant between-patient pharmacokinetic variability. Over the past years, data have emerged demonstrating a link between antiretroviral drug concentrations and efficacy or side-effects. As a result, the issue of therapeutic drug monitoring for these compounds are arisen; many published studies provided evidence that plasma concentrations contributes to therapeutic response. However, further information must be collected to define more precisely the therapeutic concentrations and the indications of therapeutic drug-monitoring for each drug. |

Enemies Wanted: No Experience Necessary - The Army?s Addiction to Enemies Inhibits Analysis of the Operational Environment | A boxing match is not a punching contest. In any bout, there is a wide range of skills on display. A fighter wants to land punches, but there is no telling how the match will unfold even after he lands them. So he trains to defend, to avoid, to counter, to clinch. Between every round, he makes an assessment of his opponent’s strategy and tactics, and draws upon his hard-learned skills to find the right way to fight this fight. He doesn’t stand flat footed and punch away because he’s stronger. He doesn’t train only to perfect his own strengths irrespective of what else may happen in the ring. That is a recipe for defeat. And it is exactly how the U.S. Army approaches modern conflict. |

A study on the location of ~(99)Tc~m-HMPAO in neurons of rat brain | Objective To study the location of 99Tcm-HMPAO in neurons. Methods Cerebral blood flow autoradiography was done in 3 normal rats and 11 rats with right middle cerebral artery occlusion(MCAO) and observed with light and electron microscope. Results 99Tcm-HMPAO silver particles were observed in the cytoplasm and processes of normal neurons and the distribution was not even among different neurons. In MCAO rats, the distribution of 99Tcm-HMPAO silver particles showed diffuse decrease in ischemic penumbra and almost disappeared in the infarcted core. Conclusion The retention of 99Tcm-HMPAO in neurons might be correlated with the metabolic process taking place in cytoplasm. |
Constraining the CKM angle γ and penguin contributions through combined B → πK branching ratios | Motivated by recent CLEO measurements of $B\to\pi K$ modes, we investigate their implications for the CKM angle $\gamma$ and a consistent description of these decays within the Standard Model. Interestingly it turns out that already the measurement of the combined branching ratios $B^\pm\to\pi^\pm K$ and $B_d\to\pi^\mp K^\pm$ allows to derive stringent constraints on $\gamma$ which are complementary to the presently allowed range for that angle. This range, arising from the usual fits of the unitarity triangle, is typically symmetric around $\gamma = 90^\circ$, while our method can in principle exclude a range of this kind. Consistency within the Standard Model implies furthermore bounds on the ratio $r\equiv|T'|/|\tilde P|$ of the current-current and penguin operator contributions to $B_d\to\pi^\mp K^\pm$, and upper limits for the CP-violating asymmetry arising in that decay. Commonly accepted means to estimate $r$ yield values at the edge of compatibility with the present CLEO measurements. |
Cruelty as the "medicine" treating an unbalance in the development of the brain's hemispheres. | A neurophysiological cause for the cruelty expressed by the Nazis during the Holocaust is suggested, as well as certain tests for the adult population intended to reveal such a social danger. The cause is seen as an unbalance in the development of the brain's hemispheres. It is assumed that this unbalance can occur in a nation which is under an extremely intensive stress of intellectual (cultural) development, which might be, for example, because of technological competition between nations/countries. Cruelness is purposed to prevent (further) development of the right hemisphere. |
Blood flow effects in magnetic resonance imaging. | In this review, the principal flow effects in current MR imaging (MRI) techniques are presented. The first section is a general review of basic aspects of blood flow relevant to MRI and a brief summary of prior approaches to MR flow measurement and reported MRI flow effects. The second section contains a more detailed discussion of three basic underlying effects of flow that affect MRI: washout of saturated spins, displacement of excited spins, and phase shifts of excited spins due to motion along magnetic field gradients. The third section presents some experimental results to demonstrate the difference in washout effects observed with selective and nonselective refocusing pulses in spin-echo MRI. The final section considers some of the possible approaches to measurement flow with MRI. |
Bloody nipple discharge in infancy: a case report and recommendations for management. | We report a 5-month-old male infant with benign unilateral bloody nipple discharge, and we present a brief review of 20 previously described cases of bloody nipple discharge in infancy. On the basis of our case and previous reports, we offer recommendations for the management of the bloody nipple discharge in the first year of life: (1) diagnosis should be based on noninvasive diagnostic procedures, in the absence of dubious ultrasound or cytological diagnostic findings; (2) the condition resolves spontaneously, and surgical intervention should be avoided; (3) manipulation of the nipple can prolong the bleeding; (4) antibiotics should be given only in the presence of clear clinical and cytological signs of infection; and (5) parent reassurance is an important part of infantile bloody nipple discharge management. |
The neurology of aging: normal versus pathologic change. | Mild changes in neurologic function occur with aging but generally do not substantially interfere with everyday activities unless disease intervenes. Not infrequently, older adults experience minor impairment in memory, speed of cognitive processing, sleep, vision and hearing, vibratory sense in the lower extremities, and gait and posture. In general, these changes correspond with age-associated neuroanatomic changes (eg, diminished brain weight), but there is wide variability in the extent to which these changes occur. Often, "normal" neurologic changes are difficult to distinguish from impairment associated with disease. |
Repeated moral hazard with history-dependent preferences | This paper introduces history-dependent preferences into the principal-agent framework. In this setup, the Inverse Euler equation breaks down. The paper characterizes optimal ::: contracts and shows that the wedge between the principal’s rate of return to saving and the agent’s shadow rate of return is not positive in general. However, the wedge is positive given a rather weak assumption on the agent’s marginal rate of intertemporal substitution. This points out an intimate link between the sign of the wedge and regressive/progressive taxation of wealth. Finally, the paper explores differences between the two most common ::: models of history-dependent preferences. |
Trials and tribulations of a transform | The McCutchen transform is the combination of a Fourier transform with a square-root geometrical distortion. For a type of rotational-deblurring problem, it would be desirable to extend this transform in a 'natural' fashion. This talk summarizes some of the rewards and many of the frustrations arising from attempting this extension. |
Energy, helicity and crossing number relations for complex flows | Algebraic and topological measures based on crossing number relations provide bounds on energy and helicity of ideal fluid flows and can be used to quantify morphological complexity of tangles of magnetic and vortex tubes. In the case of volume-preserving flows we discuss new results useful to determine lower bounds on magnetic energy in terms of topological crossing number and average spacing of the physical system. New relationships between average crossing number, energy and helicity are derived also for homogeneous vortex tangles. These results find interesting applications in the study of possible connections between energy and complexity of structured flows. |
