State Transition Based Combinatorial Optimization | It is very difficult to solute NP problem with current technology because the set of feasible solutions is very huge. State transition based combinatorial optimization is proposed to this problem. The solution process is described with the solution of 0/1 knapsack problem. The results show that state transition based combinatorial optimization is valid. |
THE RESEARCH OF PROCESS MIGRATION MECHANISM IN CLUSTER | Process migration is one of basal mechanisms for improving the holistic performance of cluster. In the paper, we firstly discuss the key techniques of process migration in detail; secondly describe the migration of PVM in cluster; thirdly we emphatically analyze the design of process migration in Linux cluster; finally we discuss the relevant techniques in cluster. |

A rail bridge in twenty days: the Torrens to Torrens north–south corridor upgrade | The Torrens Road to Torrens River (T2T) project forms part of the overall North-South Road Corridor upgrade in Adelaide, South Australia and incorporates many components such as a new lowered motorway, road, service and pedestrian bridges, retaining walls and surface roads. This paper will discuss the Outer Harbor Railway Line bridge overpass (OHRB) that replaces an existing level crossing. |
The role of gratitude in the development of social support , stress , and depression : Two longitudinal studies | Abstract In two longitudinal studies, the authors examined the direction of the relationships between trait gratitude, perceived social support, stress, and depression during a life transition. Both studies used a full cross-lagged panel design, with participants completing all measures at the start and end of their first semester at college. Structural equation modeling was used to compare models of direct, reverse, and reciprocal models of directionality. Both studies supported a direct model whereby gratitude led to higher levels of perceived social support, and lower levels of stress and depression. In contrast, no variable led to gratitude, and most models of mediation were discounted. Study 2 additionally showed that gratitude leads to the other variables independently of the Big Five factors of personality. Overall gratitude seems to directly foster social support, and to protect people from stress and depression, which has implications for clinical interventions. |
The ATLAS tile calorimeter digitizer | We describe a readout system designed to serve the 9728 PMT channels of the ATLAS Tile calorimeter at LHC. The system will be located immediately outside the calorimeter with limited accessibility and moderate radiation levels, making reliability an important issue in the design. Six or eight boards per calorimeter module each receive and digitize high and low gain signals from six PMTs every 25 ns. Two custom designed gate arrays on each board store the data in digital pipelines until validated by the first level trigger. Selected data are formatted and read out for use by the DAQ and second level trigger systems. Configuration and control commands are distributed to the digitizer boards via the TTC clock distribution system. The current digitizer design was developed for test beam tests during summer 1999, and the final system is scheduled for volume production in the beginning of 2000. |
Study of formation mechanism of the Zhaozixiu deformed body of Huaying City,Sichuan Province | The Zhaozixiu deformed body is located in the northwest of Huaying City,and the city will be in danger directly if the deformed body collapses.After analyzing the geological structure,deformation character,geomorphic evolution,human engineering activities in detail,the author has introduced numerical simulation into the article to study the case of formation mechanism of the deformed body.The study indicates that the deformed body has been gradually formed when the middle-obliquity reverse slope,which contains coal bed,was bended and ripped during the down-cutting of canyon.And human engineering activities,that is,excavating coal,influenced the development of the deformed body to great extent. |
EXPERIMENTAL STUDY ON CRATER OF MULTI-DIRECTION SHAPED CHARGE BLASTING | The multi-direction shaped charge blasting is a new type of blasting technology.Based on the elaborating of basic theory of multi-direction shaped charge blasting and factors,the multi-direction shaped charge was designed,and the comparative experiments in blasting crater of conventional blasting and multi-direction shaped charge blasting were made in order to study the characteristics of explosion energy distribution in blasting crater.The results show that the multi-direction shaped charge can increase the volume of blasting crater,heighten the ratio of blasting energy on rock breaking,and improve the rate of explosive. |
Surface morphology and functional studies of human alveolar macrophages from cigarette smokers and nonsmokers | The surface of macrophages inhabiting the peritoneal and alveolar spaces is pleomorphic in structure. The internal structure of these cells has been widely described and is not discussed here. Although external cell morphology has been well characterized by many researchers, this subject has not been reviewed. This review, therefore, describes in detail the surface features of macrophages as well as factors affecting macrophage morphology. Morphological studies of human cells are emphasized. Functional studies are presented and, when possible, morphological parameters are correlated with cell function. Because cigarette smoking has been well studied, the effects of this pulmonary insult are described in detail. |
Health and Family Labor Force Transitions | We examine the labor force participation responses of older families to changes in the health of family members in the U.S. using the Health and Retirement Study. We estimate transitions among four labor force states for married couples: both working, husband working, wife working, and neither working. We find evidence that the onset of health problems increases the probability that the affected individual leaves the labor market. The unaffected spouse is likely to continue working if originally working, but is not likely to enter the labor market if not originally working following the onset of health problems of the spouse. Comparing our results to previous studies suggests that family responses to health changes have remained fairly stable over time in the U.S. In contrast, differences exist in family responses to health changes in the U.S. and Germany, possibly reflecting differences in the institutional environments in the two countries. |
Topic detection research based on content analysis | Based on the analysis of lots of English stories, we propose a Content Analysis-based topic detection algorithm,which aims to solve the problem existing in the topic detection research,which is difficult to detect two distinct train or explosion accidents as different events.Based on Single-Pass clustering technique,using Content Analysis,the algorithm expresses topics as two centroids: identifier centroid and content centroid.Experiment results prove that Content Analysis-based topic detection algorithm is not only easy,but also effective on solving the difficult-to-distinguish problem. |
Readiness of SiC MOSFETs for Aerospace and Industrial Applications | This paper highlights ongoing efforts to validate performance, reliability and robustness of GE SiC MOSFETs for Aerospace and Industrial applications. After summarizing ruggedness and reliability testing performed on 1.2kV MOSFETs, two application examples are highlighted. The first demonstrates the 1.2kV device performance in a prototype high frequency 75kW Aviation motor drive. The second highlights the experimental demonstration of a 99% efficient 1.0MW solar inverter using 1.7kV MOSFET modules in a two-level topology switching at 8kHz. Both applications illustrate that SiC advantage is not only in improved performance, but also in significant system cost savings through simplifications in topology, controls, cooling and filtering. |
Diffuse scattering model for radio pathloss indoors | Diffusion theory is found to provide a simple yet accurate expression for the average received radio power loss indoors in non-Line-of-Sight. Agreement with extensive indoor power measurements is found at all ranges, unlike widely used power-laws. Resulting propagation loss has a large impact on the Signal-to-Interference-and Noise behavior, materially affecting conclusions on the value of cell splitting as a method of increasing wireless network capacity. |
Soft-Information-Based Joint Network-Channel Coding for the Two-Way Relay Channel | We consider network coding for the time-division two-way relay channel (TWRC). Based on achievable rates, we study the optimal transmission time allocation for a three-phase transmission protocol. While existing network coding schemes for the TWRC perform "hard" network coding, we propose a novel soft-information-based joint network-channel coding scheme. A detailed description of the operation of each network node in our scheme is given. Moreover, we discuss optimal log-likelihood ratio quantization as well as the transmission of quantized soft information. Finally, we assess the performance of the proposed scheme using numerical simulations, including a comparison to conventional "hard" network coding and to direct transmission without relay. |
Avalanche breakdown in SOI MESFETs | Abstract Metal–semiconductor field-effect-transistors (MESFETs) have been manufactured using a highly scaled 45 nm silicon-on-insulator (SOI) CMOS technology. The MESFETs display a reversible, soft breakdown at voltages greatly exceeding that of the standard CMOS devices. The breakdown voltage increases with the length of the access region between the MESFET channel and drain contact. The measured breakdown voltage is well described by a simple model based on avalanche multiplication. |

Loss of the fibrocartilaginous lining of the intertubercular sulcus associated with rupture of the tendon of the long head of biceps brachii. | Fibrocartilage lines the intertubercular sulcus of the humerus and protects both the bone and the tendon of the long head of biceps brachii where the tendon passes through the sulcus. It provides a smooth, resilient, lubricated gliding surface on the bone. The fibrocartilage is highly metachromatic and organised into distinct superficial and deep zones. In the superficial zone, the cells are small and the fibres run parallel to the articular surface. In the deep zone, the cells are large and rounded and the coarse bundles of fibres are interwoven. In 6 of the 26 dissecting room cadavers examined the tendons were completely ruptured. In these, the fibrocartilage was replaced by loose connective tissue that resembled the synovium of the tendon sheath. The results suggest that bone fibrocartilage exhibits dynamic behaviour in response to changes in its environment, in the same manner as tendon fibrocartilage. |

Detecting Spammers via Aggregated Historical Data Set | In this work we propose a new sender reputation mechanism that is based on an aggregated historical dataset, which encodes the behavior of mail transfer agents over exponential growing time windows. The proposed mechanism is targeted mainly at large enterprises and email service providers and can be used for updating both the black and the white lists. We evaluate the proposed mechanism using 9.5M anonymized log entries obtained from the biggest Internet service provider in Europe. Experiments show that proposed method detects more than 94% of the Spam emails that escaped the blacklist (i.e., TPR), while having less than 0.5% false-alarms. Therefore, the effectiveness of the proposed method is much higher than of previously reported reputation mechanisms, which rely on emails logs. In addition, on our data-set the proposed method eliminated the need in automatic content inspection of 4 out of 5 incoming emails, which resulted in dramatic reduction in the filtering computational load. |
Progress on TiO_2-based UV Photocatalysis for Degradation of Organic Waste Gas | Volatile organic compounds(VOCs) are one of atmospheric pollutants that have caused great attentions in recent year.However there is still lack of cost-effective methods for control of these pollutants.Some traditional treatments,like adsorption,condensation and combustion,have many disadvantages such as high operating cost and secondary pollution.TiO2-based UV photocatalysis is a novel pollution control technology raised in recent years,which has characteristics of lower cost and higher removal efficiencies,without any secondary pollution.TiO2-based catalytic mechanism,catalyst preparation and structural characterization were reviewed.Applications of TiO2-based UV photocatalysis in waste gas including chlorine,aromatic hydrocarbons,aldehydes and ketones,a nitrogen-containing sulfur-containing treatment were also introduced.Potential applications of TiO2-based UV photocatalysis were also briefly discussed. |
Binding of sperm to somatic cells via HLA-DR. Modulation by sulfated carbohydrates. | We have shown previously that human sperm bind and enter leukocytes expressing surface HLA class II molecules. In the present study, mutant B lymphoblastoid cells and HLA-DR-transfected murine 3T3 fibroblasts are used to confirm that HLA class II molecules are somatic cell receptors for sperm. Further, for isolated HLA-DR expressed on murine cells, we show that sperm receptor activity requires the presence of sulfated carbohydrates. As carriers of multiple HLA-DR binding ligands, sperm may 1) mimic the target cell-activating effects of anti-DR antibody and 2) bind HIV through CD4-like or alternate receptors. By these or other mechanisms, sperm/somatic cell interactions in the female reproductive tract may affect fertility and potentiate the sexual transmission of AIDS. |
Total Synthesis of (+)-Pyrenolide D. | An efficient approach to stereoselective construction of a spiro-γ-lactone core structure via BF3-promoted formal [3 + 2] annulation of aldehydo-aldose derivatives with γ-methylene-γ-butyrolactone has been developed. The spiro-γ-lactone derivative was then used in an efficient total synthesis of (+)-pyrenolide D. The developed chemistry paves the way for total synthesis of structurally diverse natural products containing spiro-lactone cores. |
Antibodies to liposomes, phospholipids and phosphate esters | Abstract Polyclonal and monoclonal antibodies to liposomes having various phospholipid compositions have been produced. Binding of the anti-lipid bilayer antibodies is influenced both by the chemical composition and the physical state of the liposomal lipids. The antibodies to liposomes have a ‘subsite’ in the binding site that recognizes small soluble phosphorylated haptens such as nucleotides (e.g. ATP). The capacity of anti-liposome antibodies to bind to phosphate is also shared by antibodies to numerous other substances, including lipid A from Gram-negative bacterial lipopolysaccharide, cardiolipin, DNA, polynucleotides, and lipoteichoic acids from Gram-positive bacteria. Because of similarities of chemical structures between all of these molecules widespread immunological cross-reactivities are observed. |

Memory and the Fictional Imagination: Creating Memories | At the end of Woody Allen’s film Another Woman (1988), the question is asked: ‘Is a memory something you have or something you’ve lost?’ This is a pleasing formulation because of the resonance with the idea that a memory may be treasured — a mental keepsake — but also a placemarker for something departed. A memory is perhaps what the mind has left of something the individual has lost; sometimes it is all we have left. |

The Cost-Efficiency of a Guaranteed Jobs Program: Really? A Response to Harvey | Abstract Responding to Harvey’s argument that a Guaranteed Jobs program would be more cost-efficient than a Guaranteed Income program, this paper points out several costs related to the latter that are not included in Harvey’s cost comparisons, mostly related to the administrative costs of operating a Guaranteed Jobs Program, which tends to be much more complex and high maintenance. This paper also points out that the unemployment rate would shift in response to the program, and that some unnecessary jobs would most likely need to be created if the program is to guarantee a job for everyone. However, the paper concludes that the public projects imagined as part of a guaranteed jobs program have merit on their own grounds, and should not be dismissed. |
Prioritizing replenishments of the piece picking area | Having sufficient inventories in the forward or piece picking area of a warehouse is an essential condition for warehouse operations. As pickers consume the inventory in the piece racks, there is a risk of stockout. This can be reduced by the timely replenishment of products from the bulk reserve area to the forward area. We develop and compare three policies for prioritizing replenishments for the case where order picking and replenishments occur concurrently because of time restrictions. The first policy, based on the ratio of available inventory to wave demand, reduces the number of stockouts considerably. The other two more sophisticated policies reduce the number of stockouts even more but require much more computation time, and are more costly in terms of implementation, maintenance and software updates. We present the results of implementing one of these policies in the warehouse of a large cosmetics firm. |
Determining the Proper Capacity of Electric Vehicle Charging Station | The problem of determining the proper capacity of electric vehicle charging station is studied in the presented paper. Based on the expected arrival rate and the expected charging time, we calculate the proper capacity that guarantees electric vehicles get service better than a given lower bound which is termed the loss of charging probability. The problem is studied by using certain queueing models. We first formulate the problem as a queueless model of type M/M/n/n, known as the Erlang loss system. And then the M/M/n/K type queueing model is formulated to consider the parking space constraint. Results of the study may be used for designing the electric vehicle charging station. |
Selective Si-Si Bond Cleavage in Decaisopropylbicyclo[2.2.0]hexasilane. A Route to Sterically Hindered 1,4-Dichlorocyclohexasilanes | The Si-Si bond cleavage reaction of decaisopropylbicyclo[2.2.0]hexasilane with PdCl2(PhCN)2 gave cis- and trans-1,4-dichlorocyclohexasilanes. X-ray crystallography of these products show sterically distorted chair conformations of the Si6 rings. The cis- and trans-cyclohexasilane show rather different absorptions in the UV spectra. By treatment with sodium, both isomers reproduced the bicyclo[2.2.0]hexasilane quantitatively. |
Evaluation of Electricity Generation From Underground Coal Fires and Waste Banks | A temperature response factors model of vertical thermal energy extraction boreholes is presented to evaluate electricity generation from underground coal fires and waste banks. Sensitivity and life-cycle cost analyses are conducted to assess the impact of system parameters on the production of 1 MW of electrical power using a theoretical binary-cycle power plant. Sensitivity analyses indicate that the average underground temperature has the greatest impact on the exiting fluid temperatures from the ground followed by fluid flow rate and ground thermal conductivity. System simulations show that a binary-cycle power plant may be economically feasible at ground temperatures as low as 190 {sup o}C. |
Caudal injectate can be reliably imaged using portable ultrasound – a preliminary study | Summary ::: Background : Correct caudal cannula placement is essential for block success and the avoidance of complications. The aim of this study was to assess the use of a saline injection test bolus with ultrasound (US) imaging to identify correct cannula placement for caudal anesthesia. ::: ::: Methods : A prospective observational study of 60 children undergoing caudal anesthesia. A Sonosite 180 Plus (Sonosite Inc., Bothwell, WA) was used to image the spine and look for caudal space expansion secondary to saline injection. ::: ::: Results : Saline test bolus correctly identified position in 96.5% of all subjects, and was 100% successful in children under 2 years of age. ::: ::: Conclusions : These preliminary results suggest saline test bolus under US imaging is a reliable indicator of correct cannula position for caudal block. We found it safe, quick to perform, and provided additional useful information. |
Rescattering production of dileptons in nucleus-nucleus collisions | We present a space-time formulation for the rescattering of hard partons produced in primary QCD subcollisions within a nucleus-nucleus collision. As an application we calculate the rescattering rate for dilepton production in 100 GeV/A+100 GeV/A uranium-uranium collisions. |
Study on Casing Wear Protection Technology and its Application in Deep Wells | Causes of casing wear and its effects on casing strength in drilling operations of deep well,ultra-deep well,extended reach well and horizontal well are analyzed in this paper.Structural principles,major performance parameters and applications of the casing wear protector are introduced in detail as well.Application results indicate that the tool is safe,reliable and easy to operate and can effectively prolong well's life and reduce casing repair,casing patching or well workover in later stage. |
CRO-GRID security management system | Computer grids are briefly described as highly distributed systems of computer resources which cooperate together towards creating a reliable, scalable dynamically changeable system for providing resources and services to users. Dynamical nature of grid creates additional security challenges. This paper gives an overview of security demands which a grid security system must overcome. First, an explanation of the grid specific security demands is given. Then, an overview of the available grid security systems, first the concepts they use and later technologies that implement those concepts is given. Furthermore, we use these concepts to define our own architecture for enabling security in a grid environment and enhancements to usual grid security mechanisms. We conclude with a description of future steps and how these steps will improve our system. |
A treatable multifocal motor neuropathy with antibodies to GM1 ganglioside | We report 2 patients with a treatable, immune-mediated motor polyneuropathy associated with antibodies to defined neural antigens. In these patients asymmetrical weakness developed in one arm and progressed over 2 to 3 years to involve the other arm, legs, and trunk. Both patients were initially diagnosed as having lower motor neuron forms of amyotrophic lateral sclerosis. However, repeated electrophysiological testing eventually showed multifocal conduction blocks in motor but not sensory fibers compatible with patchy selective demyelination. Serum testing by thin-layer chromatography and enzyme-linked immunosorbent assay revealed that both patients had high titers of antibody directed against GM1 and other gangliosides. Initial therapeutic trials of prednisone (100 mg daily for 4 to 6 months) and plasmapheresis were unsuccessful. Treatment with cyclophosphamide, however, was followed by marked improvement in strength in both patients. |
Consequences: Interaction and Impact | In the final chapter the author addresses the effects of the radical right and makes the point that the East European radical right has lasting effects not only on its nearby competitors but also on the larger political system. The analysis of government participation and policy making in coalition government (as in Poland, Slovakia, Romania, and more recently Latvia and Bulgaria) is complemented by a study of interaction patterns between the radical right and mainstream actors, including the state. The most important effect is not the implementation of a distinct set of radical right policies but rather the radicalization of (parts of) the mainstream (instead of mainstreaming the radical right). This poses severe challenges to the democratic quality of the political systems in question. |
FEDSOL: program user's manual and economic optimization guide for solar federal building projects. Final report | A user's manual for the FEDSOL computer program is provided. The FEDSOL program determines the economically optimal size of a solar energy system for a user-specified building, location, system type, and set of economic conditions it conducts numerous breakeven and sensitivity analyses and it calculates measures of economic performance as required under the Federal Rules. The economic model in the program is linked with the SLR (solar load ratio) design method developed to predict the performance of active systems. The economics portion of the program can, however, be used apart from the SLR method, with performance data provided by the user. |
Local interdiffusion at buried TiN/Si interfaces with scanning probes | This study proposes a novel scanning-probe-based approach to induce local interdiffusion at buried interfaces. Scanning-probe oxidation (SPO) was performed on a thin TiN layer on a Si substrate with ethanol menisci. The diffusion of Si and Ti at the interface was observed using Auger electron analysis and photoelectron spectroscopy and mapping. The results of photoelectron spectroscopy revealed that SPO converted the TiN layer into TiNxOy. The significant conductivity of TiNxOy was verified by conductive atomic force microscopy. Joule heating in the conductive TiNxOy induced Si diffusion in the amorphous TiNxOy layer. |
80ºC, 50-Gb/s Directly Modulated InGaAlAs BH-DFB Lasers | Direct modulation at 50 Gb/s of 1.3-µm InGaAlAs DFB lasers operating at up to 80°C was experimentally demonstrated by using a ridge-shaped buried heterostructure. |
NEW SYNTHESIS OF METHYL 2-TRIORGANOSILYL-3-BUTENOATES AS A NEW SYNTHON OF 3-METHOXYCARBONYLALLYL ANION | Methyl 2-triorganosilyl-3-butenoates, which are selectively obtained from the carboxylation of the corresponding allylsilanes via allylic aluminates, react with various kinds of electrophiles to give γ substituted (E)-α,β-unsaturated esters in highly regio and stereoselective manner with the aid of a Lewis acid. |
Leiomyoma of vulva mimmicking bartholin cyst | Leiomyoma of vulva are uncommon findings in women of reproductive age group. It is often misdiagnosed as Bartholin cyst as unilateral swelling of vulva in women of reproductive age group is commonly a bartholin cyst or abscess. We describe a case of leiomyoma that clinically mimicked bartholin duct cyst. Identification of leiomyoma or leiomyosarcoma is necessary because of risk of recurrence, need of radiation and or chemotherapy in addition to surgical excision whereas standard treatment for bartholin cyst is marsuplisation. |
Trastuzumab plus GM-CSF for patients with trastuzumab-resistant, HER2-overexpressing metastatic breast cancer: Pilot study | 803 Background: Preclinical data suggest that the anti-tumor activity of trastuzumab (Herceptin) is partly due to antibody-dependent cellular cytotoxicity (ADCC) by immune effector cells. Granulocyte-macrophage colony-stimulating factor (GM-CSF, Leukine) enhances ADCC by stimulating a variety of effector cells, including natural killer cells. In this pilot study, we tested the clinical antitumor effect of Herceptin plus GM-CSF in women with Herceptin-resistant metastatic breast cancer. Methods: Eligible patients (pts) had measurable, HER2-overexpressing, metastatic breast cancer; progressive disease (PD) after Herceptin ± chemotherapy; and good performance status (ECOG 0–1). Herceptin was given at 4 mg/kg IV followed by 2 mg/kg every wk for 4 wk (1 cycle). GM-CSF was given at 250 mcg/m2 SC daily until absolute neutrophil count (ANC) >10,000/mm3, then every other day while ANC was below 10,000/mm3. Treatment was continued until PD or intolerable toxicity. The primary endpoint was tumor response (including ... |
A performability analysis of mobile wireless sensor networks with probabilistic model checking | This article presents a method to check the per-formability of mobile wireless sensor networks. After introducing this method based on formal methods, we apply it to check the performability of an application in a hospital context. A pilot application was deployed to check its properties. We propose to model some aspects of its specifications before checking them. We use a process calculus suitable for reliability and performance modelling of mobile systems. These models are then translated into the language of PRISM, a probabilistic model checker which enables checking of considered properties. |
Cognitive and non-cognitive behaviors in an APPswe/PS1 bigenic model of Alzheimer's disease. | Neuropsychiatric signs are critical in primary caregiving of Alzheimer patients and yet have been relatively ignored in murine models. In the present study, APPswe/PS1 bigenic mice had higher levels of irritability than non-transgenic controls as measured in the touch escape test. Moreover, APPswe/PS1 mice showed poorer nest building than controls and a higher duration of immobility in the forced swimming assay. These results are concordant with the hypothesis of increased apathy and depression-like behavior in an Alzheimer’s disease model. In addition, APPswe/PS1 bigenic mice were deficient in retention of passive avoidance learning and left–right discrimination learning, concordant with previous findings in other Alzheimer-like models. |

hep-ph/9407205 Structure of photon and the muon puzzle. ∗ | In this talk I first briefly explain the puzzle presented by the high muon content observed in air-showers which point to the ultra high-energy γ sources like the HER-X-1. Since it had been suggested that a possible explanation of the puzzle might come from the effects of the hadronic structure of the photon, I briefly explain the concept of photon structure function and comment on the uncertainties in the predictions of the σ tot γp . Then I show that while the current experiments at the e + e - (TRISTAN and LEP) and ep (HERA) colliders have seen clear evidence for the hadronic structure of the photon, the observed muon excess in the air shower experiments, if confirmed by other experiments to be at the same high level, can not be explained in terms of the photon structure function. |
Esters of α-sulfomaleic anhydride as powerful electrophiles for polyolefin functionalization | New electrophilic derivatives of maleic anhydride were synthesized to test their reactivity in ene reactions with the terminal double bond of hydrocarbon polymers. The methyl ester and new ethyl ester of sulfomaleic anhydride (SMA) were reacted with 2,2,4-trimethyl-1-pentene 3, which is a model compound for the end group of the hydrocarbon polymers. The SMA esters were more oleophilic than SMA itself, but many side reactions occurred. Higher alkyl esters of SMA could not be synthesized. Two silyl esters of SMA, trimethylsilyl and t-butyldiphenylsilyl, were also synthesized and reacted with 3; ene reactions proceeded well in bulk, but the ene adducts decomposed upon heating. The powerful dienophilic character of these SMA esters was demonstrated by a series of [4 + 2] cycloadditions. |

Feynman path centroid dynamics for Fermi–Dirac statistics | In this communication the centroid molecular dynamics (CMD) method is tested for systems of fermions using a modified version of the expression for the fermion Feynman path centroid density derived in a recent publication [J. Chem. Phys. 110, 3647 (1999)]. The method is applied to a model system consisting of two noninteracting fermions in an anharmonic potential well and the position autocorrelation function is computed. The exact fermion position autocorrelation function exhibits a longer period of oscillation when compared to the bosonic case. This shift is due to the anharmonic nature of the given potential function where the level spacing decreases with the increase of energy. The CMD results agree very well with the exact quantum mechanical results for this example. This indicates, along with the previous results on a boson system, that quantum statistics can in principle be incorporated into the CMD method without any degradation of the accuracy of the approximation. |

Doctors must avoid jargon when talking to patients, royal college says | Doctors should speak slowly and avoid using jargon with their patients, the Royal College of General Practitioners (RCGP) has said.1 ::: ::: A report by the college said that doctors often used words that were unfamiliar to patients or that patients did not fully understand. “Doctors may use familiar words in unfamiliar ways,” it said. “For example, when health practitioners use the term ‘chronic’ they frequently mean ‘persistent,’ whereas a common alternative understanding of the word is to mean ‘severe.’” ::: ::: The report said, “Doctors … |
Robust H∞ Sliding Mode Controller Design of a Class of Time-Delayed Discrete Conic-Type Nonlinear Systems\vphantomP | This paper studies the H∞ sliding mode control (SMC) problem for a class of discrete-time conic-type nonlinear systems with time-delays and uncertainties. The nonlinear terms satisfy the conic-type constraint condition that lies in a know hyper-sphere with an uncertain center. By choosing a proper Lyapunov candidate, sufficient conditions are derived to ensure the asymptotic stability of the sliding mode dynamics while achieving a prescribed H∞ disturbance attenuation level and finally converted into a minimization problem. The controller is constructed to guarantee the discrete-time reach condition and maintain the states on the prespecified sliding surface. A simulation result and a practical example related to the Chua's circuit are given at last to show the validity of our SMC strategy. |

Document Changes: Modeling, Detection, Storage and Visualization (DChanges 2016) | The DChanges series of workshops focuses on changes in all their aspects and applications: algorithms to detect changes, models to describe them and techniques to present them to the final users are only some of the topics we investigate. The workshop is open to researchers and practitioners from industry and academia. This year, we would like to focus on the application of change-tracking and diff algorithms to documents that are collaboratively edited via the web. We will also follow up on the discussion of DChanges 2015 about algorithms and interfaces to better understand and exploit detected changes, and about standards for modeling and transmitting changes. Particular attention will also be given to the use of diff, change tracking, and versioning techniques in the field of digital humanities. |

Characterisation and oxidative crosslinking of sugar-beet pectins extracted from cossettes and pulps under different conditions | Abstract Pectins have been extracted from sugar-beet cossettes by a sequential treatment with water, oxalate, hot dilute acid and cold dilute alkali, and from pulp with different conditions of pH and temperature. All these samples have been chemically characterised and tested for their gelling capacity with persulphate. Pectins from cossettes have characteristics very close to those previously extracted in the same way but are not able to give gels by addition of persulphate. On the other hand, some, but not all, of the pectins from pulp can gel under these conditions. No simple relationship was found between the gelling ability and the chemical characteristics of the pectins. |

Sleep and Sleep States: Histamine Role | Histamine is a signaling molecule in the immune system, the skin, the stomach, and the nervous system of vertebrates. Histaminergic neurons are located exclusively in the tuberomamillary nucleus of the posterior hypothalamus and extend their axons throughout the central nervous system. These neurons are active during the awake state but not during sleep. Three of the four known histamine receptors are widely expressed in the brain. H1 and H2 receptors are mostly excitatory and H3 is an inhibitory auto- and heteroreceptor. Close mutual interactions between histaminergic and other aminergic and peptidergic systems form a network with basic homeostatic functions, including sleep–wake regulation, feeding, drinking, synaptic plasticity, learning, and memory. |

Reaction Coordinate, Free Energy, and Rate of Intramolecular Proton Transfer in Human Carbonic Anhydrase II | The role of structure and dynamics of an enzyme has been investigated at three different stages of its function including the chemical event it catalyzes. A one-pot computational method has been designed for each of these stages on the basis of classical and/or quantum mechanical–molecular mechanical molecular dynamics and transition path sampling simulations. For a pair of initial and final states A and B separated by a high free-energy barrier, using a two-stage selection process, several collective variables (CVs) are identified that can delineate A and B. However, these CVs are found to exhibit strong cross-coupling over the transition paths. A set of mutually orthogonal order parameters is then derived from these CVs and an optimal reaction coordinate, r, determined applying half-trajectory likelihood maximization along with a Bayesian information criterion. The transition paths are also used to project the multidimensional free energy surface and barrier crossing dynamics along r. The proposed schem... |
From insertion of rhodium acetate paddlewheels into functionalized 7-azaindole hydrogen-bonded dimers to infinite architectures. | In order to take advantage of the peculiar mode of interaction consisting in the combination of hydrogen and coordination bonding displayed by the 7-azaindole core towards tetraacetate paddlewheel type complexes, a series of new derivatives, bearing peripheral interacting sites at the position 3, have been prepared and their self-assembly into dimeric H-bonded species was established in the solid state. Furthermore, the heterochelate mode of binding was exploited both in the solid state and in solution using [Rh(2)(OAc)(4)] paddlewheel to generate discrete capped complexes resulting from the coordination of the pyridyl nitrogen atom to the axial position of the Rh(ii) cations and hydrogen bonding between the pyrrolic NH and an oxygen atom of one of the equatorial acetate groups. The extension to infinite hybrid networks was achieved using derivatives bearing self complementary H-bond donor and acceptor groups such as a carboxylic moiety. |
A chance for a propaganda coup? The Reagan administration and The Day After (1983) | In November 1983, in a period of revived nuclear fears and immediately before the deployment of Pershing II missiles in Western Europe, ABC aired The Day After, a film depicting the aftermath of a nuclear attack on the United States. The broadcast attracted around 100 million viewers, making it the most-watched television film in the history of the medium, and the nuclear freeze movement heavily exploited the movie as a propaganda instrument. Based primarily on a multitude of government documents, which are processed for the first time, this article attempts to show how the Reagan administration, in cooperation with conservative private organizations, reacted to The Day After with a comprehensive and well-coordinated propaganda campaign to take over the movie to promote its own nuclear policies, particularly the concept of a strong deterrence and arms control. Thereby, this article provides a case study both of Reagan administration propaganda and of the propagandistic significance of cinema and fictional... |
[Surgical management of mandibular condylar fractures in adults in France, 2005]. | INTRODUCTION ::: The authors had for aim to present the latest trends in the surgical management of mandibular condylar fractures in France, in 2005. ::: ::: ::: MATERIAL AND METHODS ::: One hundred maxillofacial surgeons were questioned on the surgical management of condylar fractures and indications. Results were presented at the 41st Congress of Stomatology and Maxillofacial surgery. ::: ::: ::: RESULTS ::: The overall reply rate was 70%. Condylar fractures are generally managed in teaching hospitals. Open reduction and fixation was deemed appropriate in low subcondylar fractures in 76% of the cases, in 10% for diacapitular fractures. Therapeutic details and indications were a matter of huge variability. ::: ::: ::: DISCUSSION ::: This survey highlighted the absence of any consensus as far as condylar fractures are concerned. It seems that the higher the fractures are, the lesser they are approached. |
Discrete models of infectious disease spread | In this paper we deal with discrete models of infectious disease spread. We come out from classical continuous Kermack-McKendrick compartmental approach which is transformed into the form of discrete simulation model. Next we generalize it by defining a concept of temporal communities which every individual is incorporated into. Temporal communities are built dynamically according to living rules from individuals in various stage of infection. Proper creation on communities is ensured by formerly developed algorithms including nested simulation. |
Phase locking of biological clocks | Radial isochron clocks (RICs) and their response to external signals and coupling with other RICs are studied. RICs are derived as phase approximations to self-sustained oscillators. Their response to single impulses (phase resetting) and to repetitive impulses is determined. This response may be harmonic or chaotic. Finally, the effect of coupling between clocks is studied. Simple coupling is shown to exhibit rhythm splitting like that observed in fish and small mammals. New phase locking results for general weakly coupled RIC systems are also derived. |
Fulfilling engineering program objectives through service learning campaigns in developing countries | AbstractThe civil engineering profession, in an adaptive reaction to emerging roles for civil engineers, is recognizing the need for new engineers to possess a more robust skill set than just the typical design background. This paper describes the efforts of Clemson Engineers for Developing Countries (CEDC) to fulfill the more nontraditional and often unaddressed learning outcomes noted by ASCE’s Civil Engineering Body of Knowledge for the 21st Century as important prerequisites for licensure. The learning outcomes are addressed through ongoing international service learning projects in the Central Plateau of Haiti. The paper focuses on the following four outcomes and their fulfillment methods: leadership, teamwork, communication, and globalization. CEDC’s unique organizational structure is critical to the fulfillment of these outcomes and facilitates a student-led learning environment. The student-led organization has allowed students to set up their own fundraising mechanisms, recruit interdisciplinary ... |
Chemical Kinetic Studies Using Ultraviolet Cavity Ring-Down Spectroscopic Detection: Self-Reaction of Ethyl and Ethylperoxy Radicals and the Reaction O2 + C2H5 → C2H5O2 | A laser photolysis reactor that uses cavity ring-down spectroscopic (CRDS) detection was characterized and used to measure the rate coefficients of three benchmark reactions of known importance to ethane oxidation. At 295 K and approximately 700 Pa (5.5 Torr) total pressure, we obtained the self-reaction rate coefficients of k = (1.99 ± 0.44) × 10-11 cm3 molecule-1 s-1 for C2H5 + C2H5 and k = (7.26 ± 2.4) × 10-14 cm3 molecule-1 s-1 for C2H5O2 + C2H5O2. We obtained k = (2.7 ± 0.3) × 10-12 cm3 molecule-1 s-1 for the pseudo-first-order association reaction O2 + C2H5 + Ar. We also measured the absorption cross sections of the ethyl radical, σ220 = (252 ± 42) × 10-20 cm2 molecule-1 and σ222 = (206 ± 42) × 10-20 cm2 molecule-1. Stated uncertainties are 2σ. The new rate coefficients agree with those obtained previously by other methods. The agreement confirms that ultraviolet CRDS detection is a viable tool for experimental determinations of gas-phase radical−radical and radical−molecule reaction rate coefficients. |

Nurses’ Labor Conditions, Gender, and the Value of Care Work in Post-Neoliberal El Salvador: | Neoliberal cut-backs in health-care spending have had numerous negative impacts on nurses, but we know less about how they fare when governments move from neoliberal austerity to reinvestment in their health-care systems. El Salvador is an apt case to examine for how a post-neoliberal health-care reform, launched in 2010 by the newly elected FMLN government, addresses the deterioration in nurses’ work conditions caused by austerity policies. Based mainly on focus groups, interviews and participant observation conducted in the first three years of the reform’s implementation, the analysis finds important strides for nurses, especially in increased hiring in the expanded components of public health-care, and the reduction of labor precarity in formal employment. But several problems continue to imperil nurses’ well-being, reflecting, in part, a persistent devaluation of the care work that is performed mainly by women. |
Interactive effects of fluoride and aluminum uptake and accumulation in bones of rabbits administered both agents in their drinking water | Fluoride (F) and aluminum (Al), which are known to form a strong complex, are both present in finished drinking water. The effect of F and Al on one another's tissue accumulation was determined using adult male New Zealand white rabbits. Thirty‐six rabbits (three per group) were given Purina Rabbit Chow and drinking water containing no F or AI, F alone (1, A, or 50 ppm F as NaF), Al alone, (100 or 500 ppm Al as AICI3), or a combination of F and Al, ad libitum for 10 wk. None of these treatments altered food intake or weight gain in these rabbits. However, rabbits treated with 1 ppm F and 500 ppm Al consumed significantly less water than control rabbits. The F accumulation in plasma, urine, incisors, and tibia was increased as the F addition to the drinking water increased within groups receiving a single concentration of Al. In contrast, F accumulation in plasma, urine, incisors, and tibia decreased as the Al concentration increased within groups receiving a single F concentration, indicative of decreased... |
Thermal expansion study of magnetic phase transitions in Kondo-lattice systems | High precision measurements of the thermal expansion coefficient, α(T), of the Kondo lattice systems CeAl2 and CeB6 reveal the coexistence of two second-order phase transitions at the Neel temperaturesT N =3.9 K and 2.35 K, respectively. These results are discussed with regard to the complex antiferromagnetic order known from neutron diffraction experiments on both compounds. For CeIn3, a Kondo lattice with simpler magnetic structure, only one discontinuity in α(T) occurs atT N ≃10 K. |
ROBUST ESTIMATION FOR THE DIRECTION OF ARRIVAL BY FRESNEL ZONE PLATE ANTENNA | A novel multi-beam adaptive antenna was investigated by considering the spatially distributed source model for local scattering radio propagation in cellular mobile communications. This antenna is consisted of a focusing configuration with Fresnel zone phase-correcting plate (FZP) and feeding array. The robust estimation of parameters (direction-of-arrival (DOA) and angular spread) was studied based on the generalized MUSIC algorithm and the maximum likelihood estimation in the case of coherently and incoherently spatially distributed source respectively. Simulation results show that the FZP configuration outperforms the uniformly linear array (ULA) in reducing the estimation errors of the RMS in the considered propagation environment. Therefore a robust estimation of DOA can be achieved with this novel adaptive antenna. |
Fukushima radionuclides in Vilnius/Lithuania aerosols: modelling of aerosol transport. | Measurements of activity concentrations of (131)I; (129 m)Te, (132)Te, (134)Cs and; (136)Cs, (137)Cs in aerosol were carried out in daily samples after the Fukushima accident during the period of March-April, 2011 in Vilnius. The maximum activity concentrations of (131)I and (137)Cs were found to be 3,700 μBq m(-3) and 1,040 μBq m(-3), respectively. Variations in activity ratios of (132)Te/(129 m)Te and (137)Cs/(136)Cs observed after the accident were explained by the decay of the short-lived isotopes, while those in (134)Cs/(137)Cs by the dilution effect of the Chernobyl-derived (137)Cs. It was found that different behaviours of highly volatile (131)I and (137)Cs resulted in enrichment of ground level aerosol particles by (131)I with respect to (137)Cs. Simulated activity concentrations of (137)Cs attached to aerosol particles for the Vilnius site reasonably agreed with measured activities in aerosol samples during the Fukushima accident. |

Trial by Media: An Empirical Investigation of Corporate Reputation and Stock Returns in Australia | This article examines whether investors are able to generate abnormal risk-adjusted returns in the Australian market based on media-specific firm reputational factors under market uncertainty between 2004 and 2012. The findings suggest that after controlling for crisis-centric time periods and market risk factors, contrarian trading strategies produce abnormal returns for poor corporate reputation firms but not for their good corporate reputation counterparts. Corporate reputation may be a driver of performance for poorly performing Australian firms and could be considered a stimulus for trading activity due to its explanatory capabilities. |
Influence of carbon‐coated iron nanoparticles on the Raman spectrum of liquid ethanol | Raman spectroscopy is applied to study the interactions between carbon-coated iron nanoparticles and ethanol. The spectra reveal changes in the vibrational structure of ethanol, despite dispersion of only a very small amount of nanoparticles. The hydrogen bonding network of ethanol is significantly affected in the presence of the particles. This is revealed by frequency shifts throughout the spectrum as well as the modification of the OH stretching band of the alcohol. The carbon shell of the nanoparticles does not exhibit polar groups, and hence the non-polar interactions in the system are strengthened and the hydrogen bonding is weakened.

Failed fertilization during an in vitro fertilization cycle after oral ingestion of amantadine hydrochloride | Oocyte fertilization occurred during three in vitro fertilization/embryo transfer (IVF/ET) treatment cycles of an infertile couple but failed during an IVF cycle when the husband took amantadine for prophylaxis against viral infection. Semen parameters were similar to those of other cycles attempted by this couple as well as to those of other IVF couples treated concurrently. We circumstantially suggest that amantadine, and potentially other ingestible medications or foods, while not spermicidal, may impair gamete function during IVF/ET. |

[Comparison in vitro between farm-yard manure and liquid manure (author's transl)]. | Spreading of liquid manure in a grassland ecosystem, stable since a long time when treated with farm-yard manure, brings out a great unbalance in the soil. In comparison of farm-yard manure, the liquid manure involves -- a decrease of C and N in the soil, -- a deterioration of the soil structure, -- a dangerous change in the CEC for K+ and Na+, -- an excessive stimulation of the microflora. In brief, through its composition the liquid manure involves a hyperactivity of the microglora. This heterotropic microflora is particularly mineralizing and breaks down the organic matter. The result is a temporary increase in fertility. But this stimulation of the soil life disbalances the eco-system in which -- the pool of organic matter decreases without replacement, -- the content in Ca++ and Mg++ decreases to the benefit of K+ and Na+. |
Borel reducibility and Hölder(α) embeddability between Banach spaces | We investigate Borel reducibility between equivalence relations E(X; p) = X ℕ /l p ( X )'s where X is a separable Banach space. We show that this reducibility is related to the so called Holder(α) embeddability between Banach spaces. By using the notions of type and cotype of Banach spaces, we present many results on reducibility and unreducibility between E(L r ; p )'s and E(c 0 ; p )'s for r, p Є [1, +∞). We also answer a problem presented by Kanovei in the affirmative by showing that C (ℝ + )/ C 0 (ℝ + ) is Borel bireducible to ℝ ℕ / c 0 . |
Family caregivers: a world to be investigated | A computer software architecture for an embedded computer system. The architecture includes a hierarchy of software object classes. One classification includes a common information blackboard object. Data is written to the blackboard object by processes in a protected manner, and is otherwise globally readable by all processes. A run-time executive is provided to schedule and coordinate processes. Processes register with the run-time executive at start-up. One process can know the existence and generation of data by another process. The architecture is layered in increasing levels of system abstraction. In one embodiment, the embedded system is an airborne fuel gauging subsystem. |
Finite-precision effects on graph filters | Graph filters play a fundamental role in graph signal processing. In practice, however, the finite precision nature of digital computers introduces numerical errors that can hinder their performance and jeopardize their usefulness. To mitigate these effects, this work investigates the numerical behavior of graph filters in finite-precision arithmetic. It derives a closed-form expression for the variance of the quantization noise at the filter output and shows how the filter coefficients interact with the spectrum of the shift operator to affect the numerical performance of graph filters. Based on these results, the paper then provides an optimally weighted shrinkage regularizer that can be used to design filters robust to quantization errors. Bit-accurate experiments illustrate the performance of different designs and show the importance of considering numerical effects when designing graph filters. |

Data Structures and Dynamic Memory Management in Reversible Languages | We present a method for reversible dynamic memory management based on a reversible version of the Buddy Memory system. This method supports decoupled allocation and deallocation of variable-sized records and can be applied to any reversible language with heap storage. We demonstrate how these new capabilities allow for the direct realization of commonplace data structures such as trees, heaps and queues which until now has not been practical in a reversible language. Finally, we provide a definition of our method in the high-level reversible language Janus as well as a description of its fragmentation and garbage-generation characteristics. The reversible memory management system has been fully implemented and tested in a compiler for a reversible object-oriented programming language targeting the reversible assembly language PISA. |
Decentralized guaranteed cost control for uncertain large-scale interconnected systems with multiple delays | For a class of large-scale interconnected systems with norm-bounded time-varying parameter uncertainties and multiple delays, the problem of designing an optimal guaranteed cost decentralized state feedback controller was concerned. A condition for the existence of guaranteed cost controllers was derived. It is shown that this condition is equivalent to the feasibility problem of a certain linear matrix inequality (LMI), and its solutions provide a parameterized representation of guaranteed cost controllers. Based on that fact, the design problem of the optimal guaranteed cost controller is formulated as a convex optimization problem, which can be solved by the existing convex optimization techniques. |
Intrinsic heterogeneity in expectation formation | We introduce the concept of a Misspecification Equilibrium to dynamic macroeconomics. Agents choose between a list of misspecified econometric models and base their selection on relative forecast performance. A Misspecification Equilibrium is an equilibrium stochastic process in which agents forecast optimally given their choices, with the forecasting model parameters and predictor proportions endogenously determined. For appropriate conditions on the exogenous driving process and the degree of feedback of expectations, the Misspecification Equilibrium will exhibit Intrinsic Heterogeneity. With Intrinsic Heterogeneity more than one misspecified model receives positive weight in the distribution of predictors across agents, even in the neoclassical limit in which only the most successful predictors are used.(This abstract was borrowed from another version of this item.) |

MR peritoneography in the investigation of transdiaphragmatic leakage in a peritoneal dialysis patient | Abstract Peritoneal dialysis (PD) is a safe and reliable modality of renal replacement therapy in patients with end stage renal disease (ESRD). One of the major issues that PD should overcome is its relatively higher technical failure compared with hemodialysis (HD). Dialysate leakage is a common mechanical complication that often lead to technique failure, however, it is hard to diagnose in the most positions. MR peritoneography is a promising method which can reveal the dialysate leakage visually. Here we report a PD patient suffered from dyspnea when she was under PD therapy, the patient was diagnosed with diaphragm leakage by MR peritoneography. |
Ultrasonographic findings of the various diseases presenting as calf pain | There are various causes of calf pain. The differential diagnoses affecting the lower leg include cystic lesions, trauma-related lesions, infection or inflammation, vascular lesions, neoplasms, and miscellaneous entities. Ultrasound (US) provide detailed anatomical information of the calf structures, and it offers the ability to confirm, other calf abnormalities, particularly when deep vein thrombosis (DVT) is ruled out. The purpose of this article is to review the causes of a painful calf presenting as DVT and incidental findings found as part of the work-up of DVT, and to provide a broad overview of US findings and clinical features of these pathologies. |
Study on a Communication Algorithm of Hierarchical 2PC Protocol | Based on 2PC protocol in distributed database system, this paper presents a practical communication algorithm——communication tree algorithm. With the number of nodes N, the algorithm shrinks the communication time to O(ln(N)). The basic thought is to assign proper work to the other nodes besides the communication source node, and so shorten the system responding time. Then it gives the algorithm to construct the communication tree and time function. Finally it lists some main kinds of data relative to system responding time. |
