THE "INCIDENTAL" SYSTOLIC MURMUR

The child with symptomatic heart disease is not generally much of a problem for the practicing pediatrician. He is promptly referred to a cardiac center or to a pediatric cardiologist for further evaluation. However, such is not the case with the asymptomatic child in whom a systolic murmur is heard incidentally during the course of a routine physical examination. This very Common event requires that the pediatrician decide in each instance whether the murmur can be safely ignored or whether further studies are indicated. For a detailed description of murmurs in childhood, the reader is referred to the excellent work of Castle and Craige.1 The overwhelming majority of systolic murmurs discovered in asymptomatic children are either innocent or are caused by a ventricular septal defect. The present discussion is limited to the two most common innocent murmurs, the vibratory and the pulmonic ejection murmur, and their differentiation from murmurs due to ventricular septal defect, mitral insufficiency, and other organic lesions. The venous hum, also a frequently encountered innocent murmur, is not included because it is easily recognizable by the louder diastolic component, the location over the base of the heart, and the characteristic diminution in intensity or complete disappearance with compression of the neck vessels, with movement of the head from side to side, or when the patient lies down. It is sometimes confused with the murmur of patent ductus arteriosus; but, because of the foregoing features and because it is usually located parasternally to the right rather than to the left, the differentiation is not difficult.
CUDA-level performance with python-level productivity for Gaussian mixture model applications

Typically, scientists with computational needs prefer to use high-level languages such as Python or MATLAB; however, large computationally-intensive problems must eventually be recoded in a low level language such as C or Fortran by expert programmers in order to achieve sufficient performance. In addition, multiple strategies may exist for mapping a problem onto parallel hardware depending on the input data size and the hardware parameters. We show how to preserve the productivity of high-level languages while obtaining the performance of the best low-level language code variant for a given hardware platform and problem size using SEJITS, a set of techniques that leverages just-in-time code generation and compilation. As a case study, we demonstrate our technique for Gaussian Mixture Model training using the EM algorithm. With the addition of one line of code to import our framework, a domain programmer using an existing Python GMM library can run her program unmodified on a GPU-equipped computer and achieve performance that meets or beats GPU code hand-crafted by a human expert. We also show that despite the overhead of allowing the domain expert's program to use Python and the overhead of just-in-time code generation and compilation, our approach still results in performance competitive with hand-crafted GPU code.
Transport of glycine, serine, and proline into spinach leaf mitochondria.

The transport of radioactive glycine, serine, and proline into the matrix of spinach leaf mitochondria was studied using the silicone oil centrifugation technique. The uptake of all three amino acids showed a biphasic characteristic. At concentrations higher than 0.5 mM, an apparent diffusion process dominated. The uptake was not saturable at increasing amino acid concentrations, and there was no accumulation of amino acid in the matrix (i.e., concentration was similar to that in the medium). At concentrations lower than 0.5 mM, in addition to the diffusion process, an active uptake system that accumulated amino acid in the matrix became apparent. This system was partially inhibited by rotenone, antimycin A, and carbonylcyanide-m-chlorophenyl hydrazone. Also, uptake of glycine and serine was mutually inhibitory. These two amino acids exhibited comparatively less inhibitory effect on proline uptake, and proline also did not inhibit glycine or serine uptake. The results suggest that the active uptake system consists of at least two components with different degrees of amino acid specificity. The diffusion process dominates at amino acid concentrations of 0.5 mM or higher, whereas the active uptake system becomes more prominent as the amino acid concentration decreases.

Analyzing One-Channel EEG Signals for Detection of Close and Open Eyes Activities

Finding how human brains work has always been fascinating and challenging to researchers for a long time. As the computer technology advances in the last several decades, brain computer interface (BCI) is now an important area for brain research and practice. Neurological phenomena that are special features of brain activity appearing the brain signals is the source for controlling BCI systems. Various methods have been used to capture the brain signals and analyze the neurological phenomena. One of the method is Electroencephalography (EEG) that is the recording of electrical activities along the surface of scalp. The EEG signals are usually contaminated with artifacts due to noise and biological reasons such as eye movements. These artifacts need to be detected and removed so that the signal data are clean for further analysis. In this paper, we investigate the problem of detecting closed and open eyes from EEG signals. There are a lot of eye blink detection research in the literature but most of those studies used EEG devices with multiple channels. Using a multi-channel EEG device helps increasing the accuracy but some operations such as feature selection or mounting the EEG device into the subject's head, become more complex and time consuming. In this study, we focus on analyzing ocular activity using an EEG device with only one channel.
Glycemic index of American-grown jasmine rice classified as high

The primary objective was to determine the glycemic index (GI) of jasmine rice grown in the United States (US). Secondary objective was to compare the GI of US grown jasmine rice to those grown in Thailand. Twelve healthy subjects were served all four brands of jasmine rice and a reference food (glucose), each containing 50 g of available carbohydrate. Fingerstick blood glucose was measured at 0, 15, 30, 45, 60, 90, and 120 min after consumption following a fasting state. The GI was calculated using the standard equation. The GI values for test foods ranged from 96 to 116 and were all classified as high GI foods. No difference in GI was found between American-grown and Thailand-grown jasmine rice. Although not statistically significant, observations show glycemic response among Asian American participants may be different. GI should be considered when planning meals with jasmine rice as the main source carbohydrate.
Fast method for dynamic thresholding in volume holographic memories

It is essential for parallel optical memory interfaces to incorporate processing that dynamically differentiates between databit values. These thresholding points will vary as a result of system noise -- due to contrast fluctuations, variations in data page composition, reference beam misalignment, etc. To maintain reasonable data integrity it is necessary to select the threshold close to its optimal level. In this paper, a neural network (NN) approach is proposed as a fast method of determining the threshold to meet the required transfer rate. The multi-layered perceptron network can be incorporated as part of a smart photodetector array (SPA). Other methods have suggested performing the operation by means of histogram or by use of statistical information. These approaches fail in that they unnecessarily switch to a 1-D paradigm. In this serial domain, global thresholding is pointless since sequence detection could be applied. The discussed approach is a parallel solution with less overhead than multi-rail encoding. As part of this method, a small set of values are designated as threshold determination data bits; these are interleaved with the information data bits and are used as inputs to the NN. The approach has been tested using both simulated data as well as data obtained from a volume holographic memory system. Results show convergence of the training and an ability to generalize upon untrained data for binary and multi-level gray scale datapage images. Methodologies are discussed for improving the performance by a proper training set selection.© (1998) COPYRIGHT SPIE--The International Society for Optical Engineering.

Exercise and Sleep Patterns in College Athletes

Visual stage-of-sleep analysis of the sleep EEGs of 10 college athletes under three different conditions of exercise suggests a general positive relationship between exercise and the amount of slow-wave (delta) sleep in a night's sleep as well as a stress effect of exercise obtained in the evening.
Localization Transitions in Non-Hermitian Quantum Mechanics.

We study the localization transitions which arise in both one and two dimensions when quantum mechanical particles described by a random Schr\"odinger equation are subjected to a constant imaginary vector potential. A path-integral formulation relates the transition to flux lines depinned from columnar defects by a transverse magnetic field in superconductors. The theory predicts that, close to the depinning transition, the transverse Meissner effect is accompanied by stretched exponential relaxation of the field into the bulk and a diverging penetration depth.
Long term PV system performances estimating by using only the main weather parameters data. Case of study: An Algerian Temperate climate

The main objective of this work consist to evaluate the long term performances of a photovoltaic systems according to the φ-f-chart concept in where only monthly mean values of the main weather parameters are used. The retained methodology leading evaluating the PV systems performances and that of the program developed was presented. The long term performances of a small PV system were calculated and the obtained results are compared to work presented in literature. Thus, from the obtained results it is observed that the developed program calculates the PV system performances with a good accuracy and can used as tool for a such study of any climate in where only monthly mean daily weather data are available. As application, the developed program was used to evaluate the performances of a PV system used to cover an electrical load relative to an individual house situated in Bouzareah site, in the north of Algeria and characterized by a temperate climate. From the obtained results, it is observed that the long term performances a Photovoltaic system depend strongly from the PV number modules but the storage system size have a limited effect on PV system performances and considered only for to ensure the system autonomy. From the obtained result, it is observed that the long term hourly and daily PV system performances can be evaluated for only available monthly mean values of weather data.
Understanding the impact of Schottky barriers on the performance of narrow bandgap nanowire field effect transistors.

Semiconductor nanowires have been explored as alternative electronic materials for high performance device applications exhibiting low power consumption specs. Electrical transport in III–V nanowire (NW) field-effect transistors (FETs) is frequently governed by Schottky barriers between the source/drain and the NW channel. Consequently the device performance is greatly impacted by the contacts. Here we present a simple model that explains how ambipolar device characteristics of NW-FETs and in particular the achievable on/off current ratio can be analyzed to gain a detailed idea of (a) the bandgap of the synthesized NWs and (b) the potential performance of various NW materials. In particular, we compare the model with our own transport measurements on InSb and InAs NW-FETs as well as results published by other groups. The analysis confirms excellent agreement with the predictions of the model, highlighting the potential of our approach to understand novel NW based materials and devices and to bridge materi...
OPTICAL BIOPSY OF HUMAN BLADDER NEOPLASIA WITH IN VIVO CONFOCAL LASER ENDOMICROSCOPY

Purpose: Confocal laser endomicroscopy is a new endoscopic imaging technology that could complement white light cystoscopy by providing in vivo bladder histopathology. We evaluated confocal laser endomicroscopy by imaging normal, malignant appearing and indeterminate bladder mucosa in a pilot study.Materials and Methods: Patients scheduled to undergo transurethral resection of bladder tumors were recruited during a 3-month period. After standard cystoscopy fluorescein was administered intravesically and/or intravenously as a contrast dye. A 2.6 mm probe based confocal laser endomicroscope was passed through a 26Fr resectoscope to image normal and abnormal appearing areas. The images were collected with 488 nm excitation at 8 to 12 frames per second. The endomicroscopic images were compared with standard hematoxylin and eosin analysis of transurethral resection of bladder tumor specimens.Results: Of the 27 recruited patients 8 had no cancer, 9 had low grade tumors, 9 had high grade tumors and 1 had a low g...
Effects of intra-articular botulinum toxin type A in an equine model of acute synovitis: a pilot study.

OBJECTIVE To test the hypothesis that botulinum toxin type A (BoNT-A) can attenuate lameness associated with acute synovitis in an equine model. DESIGN Four horses 2-6 yrs of age with clinically normal carpi were studied for 15 days. Kinematic gait analysis and clinical measures of lameness were conducted before and after experimental interventions. Horses were randomly assigned to either placebo (saline) or treatment (BoNT-A) groups. On day 0 of the intervention, 50 units of BoNT-A or an equivalent volume of saline (0.09%) was given into the middle carpal joints. On day 14, acute synovitis was induced with intra-articular injection of recombinant equine interleukin-1 beta (IL-1 beta) 100 ng. Synovial fluid, clinical evaluation of lameness, and kinematic gait analysis were evaluated on day 15. RESULTS Synovitis was observed on histology and cytology in all horses after IL-1 beta, indicating acute suppurative inflammation. In the BoNT-A group, one horse developed lameness, whereas the other demonstrated no change in baseline gait evaluation. No adverse effects were observed in joints injected with BoNT-A or with saline alone. CONCLUSIONS Our findings support the idea that BoNT-A can attenuate lameness in an equine model of acute synovitis. Our findings further suggest that BoNT-A might be a potential new treatment for painful arthritis; this warrants further study.
Induction of Apoptosis by Targeted Ultrasound Contrast Agents in Cancer Therapy

This research aims to develop an injectable polymer-based, platform to enable minimally-invasive targeted delivery of bioactive nano particles. Studies have shown polymer-stabilized gas microbubbles to be effective in enhancing an ultrasound image, especially those involving cancerous tumors. These contrast agents can serve a dual purpose when designed to include a specific ligand conjugated to the surface for targeting and a drug encapsulated in the shell. Research is underway to harness these techniques in the fight against cancer. Tumor necrosis factor related apoptosis-inducing ligand (TRAIL) is a protein that not only binds to cell death receptors (DR4 and DR5) on cancerous cells for targeting, but this binding also promotes apoptosis in the targeted cell. Healthy cells have decoy receptors that compete for binding. Our hypothesis is that intravenously injected TRAIL-conjugated microbubbles, when exposed to ultrasound (US), will burst to form nanoshards (n-Sh) which will transport the TRAIL to cancer cell receptors, where binding initiates apoptosis.
Organizational Knowledge Sharing in ERP Implementation: Lessons from Industry

This study examines organizational knowledge sharing in enterprise resource planning (ERP) implementation. Knowledge sharing in ERP implementation is somewhat unique because ERP requires end users to have more divergent knowledge than is required in the use of traditional systems. Because of the length of time and commitment that ERP implementation requires, end users are also often more involved in ERP implementations than they are in more traditional ERP implementations. They must understand how their tasks fit into the overall process, and they must understand how their process fits with other organizational processes. Knowledge sharing among organizational members is one critical piece of ERP implementation, yet it is challenging to achieve. There is often a large gap in knowledge among ERP implementation personnel, and people do not easily share what they know. This study presents findings about organizational knowledge sharing during ERP implementation in three firms. Data were collected through interviews using a multi-site case study methodology. Findings are analyzed in an effort to provide a basis on which practitioners can more effectively facilitate knowledge sharing during ERP implementation.
Inflation and relative price volatility in Russian food markets

Real costs result when inflation changes relative prices between products or regions. When such changes are unanticipated, resource misallocation and welfare losses are induced. Time series analysis of retail food prices in Russian markets provides estimates of anticipated and unanticipated inflation, as well as of inflation uncertainty derived from a GARCH-M model. Results indicate that distortions in relative prices were induced by the anticipated inflation rate, rather than by unanticipated inflation or a measure of inflation uncertainty. No support was found for the Lucas hypothesis that a positive relationship exists between the relative price structure and the unanticipated rate of inflation.

Extremals of functionals with competing symmetries

Abstract We present a new method of producing optimizing sequences for highly symmetric functionals. The sequences have good convergence properties built in. We apply the method in different settings to give elementary proofs of some classical inequalities—such as the Hardy-Littlewood-Sobolev and the logarithmic Sobolev inequality—in their sharp form.
Disco: running commodity operating systems on scalable multiprocessors

In this article we examine the problem of extending modern operating systems to run efficiently on large-scale shared-memory multiprocessors without a large implementation effort. Our approach brings back an idea popular in the 1970s: virtual machine monitors. We use virtual machines to run multiple commodity operating systems on a scalable multiprocessor. This solution addresses many of the challenges facing the system software for these machines. We demonstrate our approach with a prototype called Disco that runs multiple copies of Silicon Graphics' IRIX operating system on a multiprocessor. Our experience shows that the overheads of the monitor are small and that the approach provides scalability as well as the ability to deal with the nonuniform memory access time of these systems. To reduce the memory overheads associated with running multiple operating systems, virtual machines transparently share major data structures such as the program code and the file system buffer cache. We use the distributed-system support of modern operating systems to export a partial single system image to the users. The overall solution achieves most of the benefits of operating systems customized for scalable multiprocessors, yet it can be achieved with a significantly smaller implementation effort.
Anion recognition through hydrogen bonding: a simple, yet highly sensitive, luminescent metal-complex receptor

A new luminescent rhenium(I) polypyridyl-based receptor for a variety of inorganic anions has been designed and synthesized and this artificial receptor shows high affinities for halides, cyanide and acetate anions with binding constants as high as 104–105 M−1 and a detection limit as low as 10−8 M in CH2Cl2 solution.
Entropy and Charge in Molecular Evolution-the Case of Phosphate

Biopoesis, the creation of life, implies molecular evolution from simple components, randomly distributed and in a dilute state, to form highly organized, concentrated systems capable of metabolism, replication and mutation. This chain of events must involve environmental processes that can locally lower entropy in several steps; by specific selection from an indiscriminate mixture, by concentration from dilute solution, and in the case of the mineral-induced processes, by particular effectiveness in ordering and selective reaction, directed toward formation of functional biomolecules. Numerous circumstances provide support for the notion that negatively charged molecules were functionally required and geochemically available for biopoesis. Sulfite ion may have been important in bisulfite complex formation with simple aldehydes, facilitating the initial concentration by sorption of aldehydes in positively charged surface active minerals. Borate ion may have played a similar, albeit less investigated role in forming charged sugar complexes. Among anionic species, oligophosphate ions and charged phosphate esters are likely to have been of even more wide ranging importance, reflected in the continued need for phosphate in a proposed RNA world, and extending its central role to evolved biochemistry. Phosphorylation is shown to result in selective concentration by surface sorption of compounds, otherwise too dilute to support condensation reactions. It provides protection against rapid hydrolysis of sugars and, by selective concentration, induces the oligomerization of aldehydes. As a manifestation of life arisen, phosphate already appears in an organic context in the oldest preserved sedimentary record.
Medicare Cost Effects of Recent U.S. Disability Trends in the Elderly Future Implications

Objective: The authors examine how trends in disability prevalence and in inflation-adjusted per capita, per annum Medicare costs, 1982 to 1999 and 1989 to 1999, affected total Medicare costs projected to 2004 and 2009. Method: To describe disability trends, the authors applied grade of membership analyses to 27 measures of disability from the 1982 to 1999 National Long Term Care Surveys (NLTCS). This identified seven disability profiles for which individual scores were calculated. These were used to calculate sample weighted Medicare costs and cost trends. Results: Significant declines (up to 19%) in Medicare costs were found in 2004 and 2009 assuming continuation of the 1982 to 1999 disability declines and Medicare cost trends. In addition to declines in disability prevalence, inflation-adjusted per capita, per annum Medicare costs declined for nondisabled persons aged 65 to 84. Discussion: Preserving health in the growing nondisabled population did not require increased health care expenditures.

COSMIC-RAY INCREASES ASSOCIATED WITH SOLAR FLARES

Data from a standard IGY neutron monitor located on Mount Washington, New Hampshire, have been examined for possible increases associated with solar flares. The 0400 and 0900 impact zones have been located for both the standard centered dipole and the westward rotated centered dipole approximations. No increases \ensuremath{\ge}0.25% have been found for the years 1956 and 1957. An additional maximum in the mean daily cycle at the time of impact zone passage has not been observed during this period. Possible explanations for this result are presented.
Preclinical characterization of atiprimod, a novel JAK2 AND JAK3 inhibitor

We herein report on the activity of the JAK2/JAK3 small molecule inhibitor atiprimod on mouse FDCP-EpoR cells carrying either wild-type (JAK2 (WT)) or mutant (JAK2 (V617F)) JAK2, human acute megakaryoblastic leukemia cells carrying JAK2 (V617F) (SET-2 cell line), and human acute megakaryocytic leukemia carrying mutated JAK3 (CMK cells). Atiprimod inhibited more efficaciously the proliferation of FDCP-EpoR JAK2 (V617F) (IC(50) 0.42 μM) and SET-2 cells (IC(50) 0.53 μM) than that of CMK (IC(50) 0.79 μM) or FDCP-EpoR JAK2 (WT) cells (IC(50) 0.69 μM). This activity was accompanied by inhibition of the phosphorylation of JAK2 and downstream signaling proteins STAT3, STAT5, and AKT in a dose- and time-dependent manner. Atiprimod-induced cell growth inhibition of JAK2 (V617F)-positive cells was coupled with induction of apoptosis, as evidenced by heightened mitochondrial membrane potential and caspase-3 activity, as well as PARP cleavage, increased turnover of the anti-apoptotic X-linked mammalian inhibitor of apoptosis (XIAP) protein, and inhibition of the pro-apoptotic protein BCL-2 in a time- and dose-dependent manner. Furthermore, atiprimod was more effective at inhibiting the proliferation of peripheral blood hematopoietic progenitors obtained from patients with JAK2 (V617F)-positive polycythemia vera than at inhibiting hematopoietic progenitors from normal individuals (p = 0.001). The effect on primary expanded erythroid progenitors was paralleled by a decrease in JAK2(V617F) mutant allele burden in single microaspirated BFU-E and CFU-GM colonies. Taken together, our data supports the clinical testing of atiprimod in patients with hematologic malignancies driven by constitutive activation of JAK2 or JAK3 kinases.
Sexual Hookups and Alcohol Consumption Among African American and Caucasian College Students: A Pilot Study.

ABSTRACTThis study investigated college students’ sexual hooking up and its associations with alcohol consumption for men and women; furthermore, potential differences related to ethnicity were investigated. Students at a midsized southeastern university who identified as Caucasian or African American (N = 227) completed a survey assessing sexual behavior, demographics, and alcohol consumption. Heavy drinking was associated with ever hooking up, number of hookup partners, hookup frequency, and level of sexual contact during hooking up for Caucasian students, but not for their African American peers. Among Caucasians, moderate drinking men reported more intense sexual contact during hookups than their female peers who were moderate drinkers; sexual contact levels were more similar for men and women who were either nondrinkers or heavy drinkers. Limitations and strengths are discussed, as are ideas for future studies on hooking up and for educational efforts to protect against potentially negative outcomes ...
Mucosal immune responses to HIV-1 in elite controllers: a potential correlate of immune control.

There exists a unique group of persons who are able to durably control HIV in the absence of therapy. The mechanisms of control in these persons remain poorly defined. In this study, we examined CD8(+) T-cell responses in blood and rectal mucosa from 17 "elite controllers" (viral load 10,000 copies/mL), and 10 antiretroviral-treated persons (< 75 copies/mL). Production of interferon-gamma, interleukin-2, tumor necrosis factor-alpha, macrophage inflammatory protein-1 beta, and CD107a by CD8(+) T cells in response to HIV-1 Gag stimulation was measured using flow cytometry. Our hypothesis was that "polyfunctional" T cells producing multiple antiviral factors would be most abundant in mucosal tissues of HIV controllers. Mucosal CD8(+) T-cell responses were significantly stronger and more complex in controllers than in antiretroviral-suppressed persons (P = .0004). The frequency of 4-function responses in rectal mucosa was higher in controllers than in noncontrollers and patients on therapy (P < .0001). Mucosal responses in controllers were frequently stronger and more complex than blood responses. These findings demonstrate that many controllers mount strong, complex HIV-specific T-cell responses in rectal mucosa. These responses may play an important role in mucosal immune surveillance, as suggested by their relative enrichment among persons who control HIV in the absence of therapy.
The Impact of Increased Food Production on Less Developed Country Food Imports: Reply

We are pleased that Patrick Gormely correctly restates, in his own language, the same conclusions which we have reached in our analyses of the impact of less developed country (LDC) productivity growth in cereals on their import demand for these same commodities: that, unless productivity growth in cereals is accompanied by productivity growth in other sectors of the economy or by additional income increasing measures, the LDCs cereal imports will decline. As Gormely also correctly points out, the significance of these results is to dismiss statements that
Adoption factors associated with electronic health record among long-term care facilities: a systematic review

Objectives The Health Information Technology for Economic and Clinical Health (HITECH) Act created incentives for adopting electronic health records (EHRs) for some healthcare organisations, but long-term care (LTC) facilities are excluded from those incentives. There are realisable benefits of EHR adoption in LTC facilities; however, there is limited research about this topic. The purpose of this systematic literature review is to identify EHR adoption factors for LTC facilities that are ineligible for the HITECH Act incentives. Setting We conducted systematic searches of Cumulative Index of Nursing and Allied Health Literature (CINAHL) Complete via Ebson B. Stephens Company (EBSCO Host), Google Scholar and the university library search engine to collect data about EHR adoption factors in LTC facilities since 2009. Participants Search results were filtered by date range, full text, English language and academic journals (n=22). Interventions Multiple members of the research team read each article to confirm applicability and study conclusions. Primary and secondary outcome measures Researchers identified common themes across the literature: specifically facilitators and barriers to adoption of the EHR in LTC. Results Results identify facilitators and barriers associated with EHR adoption in LTC facilities. The most common facilitators include access to information and error reduction. The most prevalent barriers include initial costs, user perceptions and implementation problems. Conclusions Similarities span the system selection phases and implementation process; of those, cost was the most common mentioned. These commonalities should help leaders in LTC facilities align strategic decisions to EHR adoption. This review may be useful for decision-makers attempting successful EHR adoption, policymakers trying to increase adoption rates without expanding incentives and vendors that produce EHRs.
Development of an off-the-shelf field programmable gate array-based wireless sensing unit for structural health monitoring

This paper presents the preliminary results of an investigation on the application of Field Programmable Gate Arrays (FPGAs) to civil infrastructure health monitoring. An off-the-shelf FPGA development board available at a comparable price to microprocessor development boards is adopted in this study. Advantages, disadvantages, feasibility and design concerns when using such a reconfigurable hardware architecture for implementing algorithms for structural health monitoring in a wireless sensor unit are studied in a showcase of implementing Fast Fourier Transform (FFT) in a wireless data transmitting setting.
Some Multistep Methods for Use in Molecular Dynamics Calculations

Abstract Some multistep methods are presented that are particularly well suited for integrating the equations of motion describing the molecular dynamics of liquids and dense gases. Some tests and comparisons with other methods are described which demonstrate that a combination of a third-order explicit method for the calculation of positions and an implicit method for the calculation of velocities is particularly stable when used in computations of this type.
M-Polar: Channel Allocation for Throughput Maximization in SDR Mesh Networks

In traditional wireless networks, nodes use only a single channel per radio interface, thus limiting the overall channel diversity of the network. This restriction is due to the inherent limitations of commercially-available RF devices. With the advent of high bandwidth software-defined radios (SDRs), we now have the option of assigning multiple contiguous, independent channels to a single wireless interface. This new-found opportunity raises an important question: how do we assign contiguous channels to nodes in order to maximize overall network throughput? This question lies at the often-ignored intersection of single-radio-multi-channel and multi-radio-multi-channel assignment schemes. In this paper, we develop a protocol that assigns contiguous channels with the goal of evenly spreading the load across the multiple channels. Neighboring nodes greedily adjust their channel ranges according to channel conditions to achieve an overall pattern of partially-overlapping bandwidths that maximizes the network throughput. The end-result is a network that can dynamically adapt its bandwidth usage to the network load and the conditions of the different channels. The proposed protocol is evaluated with a prototype built upon the USRP as well as with detailed simulation.
Hiring for retention and performance

This study evaluated the usefulness of several pre-hire variables to predict voluntary turnover and job performance. Analyses showed that applicants who knew current employees, had longer tenure with previous employers, were conscientious and emotionally stable, were motivated to obtain the job, and were confident in themselves and their decision making were less likely to quit, and had higher performance within six months after hire. Results also indicated that pre-hire attitudes (employment motivation and personal confidence) did not predict turnover and performance beyond biodata (pre-hire embeddedness in the organization and habitual commitment) and the personality traits (conscientiousness and emotional stability). For all predictors but personality, the strength of the relationships weakened over time up to two years after hire. Nonetheless, organizations can avoid voluntary turnover and increase performance by basing hiring decisions on the set of predictors analyzed in this study. © 2009 Wiley Periodicals, Inc.
Formation of an Anionic Titanium(IV) Sulfido Dimer, {Na2[CpTi(μ-S)(S)]2·4THF}2, by Elimination of CpH and H2 from Cp2Ti(SH)2 upon Deprotonation with NaH

A deprotonation reaction of Cp2Ti(SH)2 with NaH in THF yields {Na2[CpTi(μ-S)(S)]2·4THF}2, generated by unexpected elimination of CpH. This anionic dimer is unique in that it is the first organometallic titanium species containing terminal sulfido ligands. The latter are stabilized by interactions with THF-solvated sodium cations, thus imposing a syn TiS configuration.
Evaluation of quantitative structure-activity predictions: comparison of the predictive power of an artificial intelligence system with human experts

In this paper, we present three new mathematical techniques for evaluating the predictive skills of structure-activity experts. The question addressed in this paper is how to evaluate the predictive ability of structure-activity experts in identifying the most active compounds of a set of drug candidates. The three proposed mathematical techniques are based on the Phi-square Distance, the Rank Comparison, and the Shuffle method, respectively. They have been used to evaluate the performance of a new computer system and three human experts in predicting the antibacterial potencies of a series of chemical compounds in five different biological tests. The expert system, an artificial intelligence structure-activity program called MULTICASE, performed significantly better than one of the human experts and somewhat better than the other two.

A Longitudinal Examination of Adolescent and Young Adult Homeless Experience, Life Course Transitions, and Health

While many have studied the antecedents of homelessness and health status among the actively homeless, no studies have evaluated the long-term health outcomes of formerly homeless adolescents and young adults. In this article, we examine the prospective association of early homeless experience and health outcomes after homelessness has subsided and whether factors that impede successful life course transitions following homeless experiences (e.g., low education attainment, depressive symptoms) mediate these associations. Among 4,651 National Longitudinal Survey of Youth–Child Study participants, formerly homeless adolescents and young adults (aged 15–25) were at greater risk of developing asthma, health-limiting conditions (HLCs), and fair/poor self-rated health over 8 years of follow-up, particularly among females. Factors that disrupt life course transitions mediated associations for asthma and HLCs. Using 20 years of life course information, this study demonstrates the enduring health risks for adolesc...
Effect of Fontan Fenestration on Regional Venous Oxygen Saturation During Exercise: Further Insights Into Fontan Fenestration Closure

Fontan fenestration closure is a topic of great debate. The body of data regarding the risks and benefits of fenestration closure is limited yet growing. Previous studies have demonstrated that Fontan patients have less exercise capacity than those with normal cardiovascular anatomy. Differences also have been noted within various subgroups of Fontan patients such as whether Fontan is fenestrated or not. This study aimed to compare trends in regional oxygen saturations using near-infrared spectroscopy (NIRS) in patients with Fontan circulations during ramping exercise to further delineate differences between patients with and without a fenestration. It was hypothesized that Fontan patients with fenestrations have better exercise times, higher absolute regional oxygen venous saturations, and smaller arteriovenous differences than Fontan patients without fenestrations. For this study, 50 consecutive Fontan patients and 51 consecutive patients with normal cardiovascular anatomy were recruited. Placement of NIRS probes was performed to obtain regional oxygen saturations from the brain and the kidney. Readings were obtained at 1-min intervals during rest, exercise, and recovery. A standard Bruce protocol was used with a 5-min recovery period. Absolute regional tissue oxygenation values (rSO2) and arterial-venous oxygen saturation differences (AVDO2) calculated as arterial oxygen saturation (SPO2)—rSO2 for normal versus Fontan patients and for fenestrated versus unfenestrated Fontan patients were compared using independent t tests. When normal and Fontan patients were compared, the Fontan patients had a significantly shorter duration of exercise (9.3 vs 13.2 min; p < 0.001). No statistically significant difference in rSO2 change or AVDO2 was evident at the time of peak exercise, at 2 min into the recovery, or at 5 min into the recovery. A small oxygen debt also was paid back to the brain in the Fontan patients after exercise, as evidenced by a narrower AVDO2 than at baseline. The comparison of Fontan patients with and without fenestration showed no statistically significant difference in exercise time, rSO2 change, or AVDO2. The Fontan patients were noted to have shorter exercise times than the normal patients and also appeared to have an alteration in postexertional regional blood flow. However, when the various Fontan subtypes were compared by presence or absence of a fenestration, no significant differences were noted with regard to change in regional oxygen saturation or arteriovenous oxygen saturation. Thus, for patients with Fontan physiology, closure of the fenestration does not seem to have an impact on the dynamics of regional oxygen extraction during exercise or recovery.
A three‐dimensional simulation of a steady approach flow past a circular cylinder at low Reynolds number

SUMMARY The three-dimensional (3D) unsteady viscous wake of a circular cylinder exposed to a steady approach flow is calculated using a fractional-step finite-difference:spectral-element method. The calculated flow fields at Reynolds numbers of 100 (2D) and 200 (3D) are examined in detail. The flow field at Re 100 is 2D as expected, while the flow field at Re200 has distinct 3D features, with spanwise wavelengths of about 3.75 cylinder diameters. The calculated results produce drag and lift coefficients and Strouhal numbers that agree extremely well with the experimental values. These 3D values at Re 200 are in better agreement with experimental values than the results of a 2D calculation at Re 200, which is expected. © 1998 John Wiley & Sons, Ltd. The flow in the wake of a circular cylinder is three-dimensional (3D), even before it becomes turbulent. The present study concerns the combined finite difference:spectral method calculation of the steady approach flow past a fixed circular cylinder at Reynolds numbers large enough for the wake to be three-dimensional, but not turbulent. The onset of the 3D wake will be discussed and it will be shown that the proper representation of the wake has a noticeable effect on the Strouhal number and the drag and lift coefficients. Specifically, the flow will be represented in terms of the primitive-variables form of the time-dependent Navier‐Stokes equations for an incompressible fluid. A fractional-step method, which is a combination of the methods of Karniadakis et al. [1] and Kim and Moin [2], is used to advance the solution in time. For a circular cylinder in a steady approach flow, the 2D vortex structures are unstable to 3D disturbances at a Reynolds number of about 170. A synopsis of the steady approach flow situation follows. When the Reynolds number, Re UD:n, where U, D, and n are, respectively, the freestream velocity, diameter of the cylinder, and kinematic viscosity of the fluid, is smaller than 40, the flow is steady with two symmetrical vortices attached to the downstream side of the cylinder. When the Reynolds number is slightly larger, ReB 60, the trailing vortex sheet becomes unstable and develops an unsteady wavy pattern. Vortex shedding occurs for 60B ReB170; the attached vortices become asymmetric and are shed alternately at a

Hyperfine Splittings of Hydrogen and Tritium. II

The spin-exchange optical polarization method was used to remeasure the zero-field hyperfine splittings of atomic hydrogen and atomic tritium. The transmission of circularly polarized rubidium resonance radiation through a flask containing rubidium, atomic hydrogen, or atomic tritium, and a buffer gas was monitored as a function of the frequency of an applied radio-frequency field. Measurements were made for hydrogen in helium, neon, molecular hydrogen, and argon buffer gases and for tritium in neon and argon buffer gases. The values of the hyperflne splittings obtained are DELTA nu (H) = 1,420,405,749.1 plus or minus 6.0 cps; DELTA nu (T) = 1,516,701,476.8 plus or minus 6.0 cps. The assigned limits of error represent the range of disagreement of the zeropressure extrapolations in the different buffer gases. The fractional pressure shifts STApressure shift in cps/mm Hg divided by the hyperfine splitiing in kMc/secl for hydrogen in helium, neon, molecular hydrogen, and argon are 4.80 plus or minus tively. Those for tritium in neon and argon are 3.24 plus or minus 0.03 and - 5.05 plus or minus 0.15, respectively. (auth) Munoz for measuring atomic partial stopping powers ( xi /sub o/) has been extended to the determination of the stopping power xi /submore » 1/ of hydrogen gas for the H/sup +/ component of a hydrogen beam. The protons in a 1-mm dia. beam are held in an orbit which is an arc of a circle of 142-cm radius, and are guided to a 1-mm dia. exit after a path length of 55.8 cm in --50 mu pressure of H/sub 2/ gas. The energy of the beam after leaving the stopping cell is measured by electrostatic deflection. No proton thus measured can have experienced a charge-changing collision in the stopping cell. In preliminary experiments protons were simulated by deuterons of twice the energy and xi /sub 1/ determined for protons of 55, 75, and 93 kev. Finally, an extended series of runs at 42.8 and 54.2 kev were made on xi /sub 1/ , and a similar extended series on xi /sub 0o/, with the apparatus arranged as in the work of Allison et al. These latter measurements for xi /sub 1/, xi , and xi /sub 0/ gave (6.12 plus or minus 0.44; 6.36 plus or minus 0.16; 2.72 plus or minus 0.16) x 10/sup -15/ ev cm/sup 2// atom, and in the same units, for the higher voltage, (6.04 plus or minus tion of the beam is known from other experiments, the charge-changing collisions may be shown to contribute 34% of the total stopping losses. The sum of the losses in kinetic energy in an electron capture and in its subsequent loss is 40 plus or minus 6 ev at42.8 kev and 54 plus or minus 9 ev at 54.2 kev, neglecting charge-changing collisions involving H/sup -/.
