Genotype Imputation in Genome‐Wide Association Studies

Imputation is an in silico method that can increase the power of association studies by inferring missing genotypes, harmonizing data sets for meta‐analyses, and increasing the overall number of markers available for association testing. This unit provides an introductory overview of the imputation method and describes a two‐step imputation approach that consists of the phasing of the study genotypes and the imputation of reference panel genotypes into the study haplotypes. Detailed steps for data preparation and quality control illustrate how to run the computationally intensive two‐step imputation with the high‐density reference panels of the 1000 Genomes Project, which currently integrates more than 39 million variants. Additionally, the influence of reference panel selection, input marker density, and imputation settings on imputation quality are demonstrated with a simulated data set to give insight into crucial points of successful genotype imputation.

Environmental issues are now a concern in many industries including the food service and hospitality industries. This paper examines environmental issues in hotels in the newly developed tourist areas of the Sinai and Red Sea. Various environmental issues were studied including environmental practices, managers attitudes towards environmental issues, future environmental practices and anticipated hotel profitability resulting from applying environmental practices. Results show an opportunity to promote environmental practices in hotels and a high level of awareness and willingness of managers to preserve the environment.
Dynamic taint analysis for vulnerability exploits detection

Untrusted Data originating from network input and configuration files, causes many software security problems. Keeping track of the propagation of untrusted data in program runtime is the main idea of dynamic taint analysis for vulnerability exploits detection. In this method data from network user input and configuration files were labeled as taint. In virtue of data flow analysis we design taint propagating algorithm, and define several taint detection policies for security-critical function which used taint data in dangerous ways that could cause vulnerability exploit. A vulnerability exploit detection prototype system was implemented. In contrast to other taint analysis systems, our prototype system has higher accuracy and vulnerability exploits coverage and low workloads.
Dimensions of uniform perceptions among service providers

Service uniforms have often been studied from the customers’ perspective, as they contribute to service expectations and evaluations. Proposes that the influence of uniform should also be considered from the service provider’s perspective. Discusses the first stage in the development of a 17‐item scale to assess service providers’ perceptions of their uniform. Identifies four dimensions of these perceptions: service approach, the look, customer influence and company identification. The emergence of the dimensions entitled service attitude and the look draws attention to issues concerned with how uniform wearers feel about themselves, and highlights the importance of the aesthetic uniform needs of the wearer. Suggests that management should give due consideration to uniform requirements as perceived by the service provider, as this is likely to impact positively on service employees and thus service orientation.
Interannual variability of equatorial Pacific CO2 fluxes estimated from temperature and salinity data

Based on atmospheric data and models, the tropical CO2 source anomaly reaches up to 2 GtC yr−1, but the respective contributions of the terrestrial biosphere and the oceans to this flux are difficult to quantify. Here we present a new method for estimating CO2 fluxes from oceanic observations based on the surprisingly good predictive skill of temperature and salinity for surface dissolved inorganic carbon. Using historical temperature and salinity data, we reconstruct the basin scale CO2 flux to the atmosphere in the equatorial Pacific from 1982 to 1993. We find that interannual anomalies do not exceed 0.4±0.2 GtC yr−1 which suggests that up to 80% of the tropical CO2 source anomaly is due to the terrestrial biosphere.
Specific heat measurements of a superconducting NbS2 single crystal in an external magnetic field: Energy gap structure

The heat capacity of a 2H-NbS2 single crystal has been measured by a highly sensitive ac technique down to 0.6 K and in magnetic fields up to 14 T. At very low temperatures, data show excitations over an energy gap (2ΔS/kBTc≈2.1) much smaller than the BCS value. The overall temperature dependence of the electronic specific heat Ce can be explained either by the existence of a strongly anisotropic single-energy gap or within a two-gap scenario with the large gap about twice bigger than the small one. The field dependence of the Sommerfeld coefficient γ shows a strong curvature for both principal-field orientations, parallel (H∥c) and perpendicular (H⊥c) to the c axis of the crystal, resulting in a magnetic field dependence of the superconducting anisotropy. These features are discussed in comparison to the case of MgB2 and to the data obtained by scanning-tunneling spectroscopy. We conclude that the two-gap scenario better describes the gap structure of NbS2 than the anisotropic s -wave model.
Interactive effects of subjective memory complaints and hypertension on learning and memory performance in the elderly

Abstract This study evaluated whether the relation between subjective memory complaints and cognitive performance is influenced by the presence of hypertension in the elderly. One hundred and five healthy older adults, 70–89 years of age, with and without hypertension treatment or diagnosis, completed a scale of subjective memory complaints. Participants were divided into those with mild memory concerns and those with minimal or no complaints. All participants completed a battery of neuropsychological tests including measures of verbal and nonverbal memory. After controlling for differences in age, gender, education, and overall intellectual ability, there were significant main effects for memory concerns and significant interactions for memory complaints and hypertension on several measures of memory performance. There were no main effects for hypertension on memory performance. Simple effects analyses of the interactions showed that the hypertensive complainers demonstrated poorer performance on measures of long-term memory and greater reliance on short-term recall than the hypertensive non-complainers. There were no differences in memory performance for the non-hypertensive groups. Among healthy elderly community-dwelling adults, those with mild subjective memory complaints in the context of hypertension demonstrated greater objective cognitive difficulties than those without hypertension as well as a greater reliance on a less efficient learning strategy. These findings suggest that memory concerns in the presence of hypertension may be important when evaluating treatment efficacy in these individuals and for identifying differences in cognitive aging.
Institutional Investors, Analysts' Recommendations, Annual Reports, Textual Analysis and Stock Returns: Evidence from SEC EDGAR 10-K and 13-F Forms

I analyze 18510 SEC EDGAR Form 10-K (annual reports), for NASDAQ, NYSE and AMEX (NYSE MKT) stocks, along with 176565 SEC EDGAR Form 13-F (quarterly reports of institutional investors holdings), and analysts' recommendations, from 2001 until 2015. I find that (i) 10-K pessimism negatively affects stock holdings after the filing, (ii) institutions do not appear to have forecasting power as to how pessimistic the annual report will be, as they do not adjust their holdings in the pessimistic stocks before the 10-K filing takes place, (iii) an increase in the number of institutional investors that hold a stock leads to an increase in stock prices after the 10-K filing (iv) institutions increase their positions in stocks that had positive returns one (1) to twelve (12) months before the 10-K filing (v) analysts' recommendations are affected by 10-K pessimism three (3) to nine (9) months after the 10-K filing, (vi) contrary to the cross-section of institutional investors, analysts do appear to have some forecasting power over how pessimistic the annual report will be, a few months before the 10-K filing month.

An investigation of prospective memory functions in people with traumatic brain injury using Virtual Week

Prospective memory (PM) refers to memory for future intentions and is critically linked to independent living. Previous laboratory research has shown that people who have sustained a traumatic brain injury (TBI) have difficulties with PM, but few of these have used measures of PM that closely represent the types of PM activities that occur in everyday life. One measure that incorporates more ecologically valid tasks, and which also allows systematic investigation of different PM task parameters (regular, irregular, and event and time based), is Virtual Week. Consequently, in the present study, Virtual Week was administered to participants with TBI (n = 18) and demographically matched controls (n = 18). Consistent with considerable prior literature, the results indicated that people with TBI had significant difficulties executing PM tasks, with these deficits more pronounced for time-based than for event-based tasks. These data point to there being a relatively global PM deficit in people with TBI. Of particular interest was the finding that the magnitude of TBI impairment was consistent across regular and irregular tasks. Because the key distinction between these tasks is that they place low and high demands on retrospective memory, respectively, these data suggest that failures of retrospective memory are not the major cause of TBI-related impairment in PM. The implications of these results for the assessment and rehabilitation of PM impairment in people with TBI are discussed.
Conductive and evaporative precooling lowers mean skin temperature and improves time trial performance in the heat

Self‐paced endurance performance is compromised by moderate‐to‐high ambient temperatures that are evident in many competitive settings. It has become common place to implement precooling prior to competition in an attempt to alleviate perceived thermal load and performance decline. The present study aimed to investigate precooling incorporating different cooling avenues via either evaporative cooling alone or in combination with conductive cooling on cycling time trial performance. Ten trained male cyclists completed a time trial on three occasions in hot (35 °C) ambient conditions with the cooling garment prepared by (a) immersion in water (COOL, evaporative); (b) immersion in water and frozen (COLD, evaporative and conductive); or (c) no precooling (CONT). COLD improved time trial performance by 5.8% and 2.6% vs CONT and COOL, respectively (both P < 0.05). Power output was 4.5% higher for COLD vs CONT (P < 0.05). Mean skin temperature was lower at the onset of the time trial following COLD compared with COOL and CONT (both P < 0.05) and lasted for the first 20% of the time trial. Thermal sensation was perceived cooler following COOL and COLD. The combination of evaporative and conductive cooling (COLD) had the greatest benefit to performance, which is suggested to be driven by reduced skin temperature following cooling.
Comparison of inertia control methods for DFIG-based wind turbines

Doubly fed induction generator (DFIG)-based wind turbines are nowadays used widely in large wind farms. Due to the fact the control system of DFIG is not based on the power system frequency, the whole inertia of the power system is reducing rapidly with the penetration of wind generation increasing. This is extremely bad for the stability of the system frequency. Thence, ancillary inertia control strategies of DFIG need to be developed to compensate for this deficiency. At the beginning of this article, the vector control system of DFIG-based wind turbines is described briefly. The inertia control methods making use of that model could later be designed out. Then, a concept called controllable virtual inertia is put out and the derivation of its formula is given in details. After the two inertia control strategies of DFIG are described fully, the mechanism that how the virtual inertia of DFIG can be manipulated is revealed: the parameters (K1, K2and K3) contained in the inertia control schemes determine proportionally the virtual inertia level of DFIG. Finally, through the simulations in Matlab/Simulink, the two strategies of inertia control for DFIG-based wind turbines which have been utilized in this work are effective for the system frequency support and the concept named as controllable virtual inertia has theory worth for further research.
THE EFFECT OF FUTURES MARKETS ON SPOT MARKET VOLATILITY: EMPIRICAL EVIDENCE FROM 3-MONTH CANADIAN BANKERS' ACCEPTANCES

Futures markets have been blamed for higher volatility in the underlying asset market. A popular belief is that trading activity in futures markets encourage speculation, which destabilizes the spot market. The alleged destabilization takes the form of higher spot market volatility. On the other hand, a favorable view is that futures trading helps stabilizing the underlying market and leads to more complete markets and enhanced information flows. The numerous papers that have studied the effect of the introduction of derivatives on the underlying assets have obtained different results. This paper analyses the effect of the introduction of futures markets on the underlying market for Canadian bankers' acceptances. More specifically this study investigates the contention that the introduction of the futures (BAX) on the Montreal exchange on April 24 th 1988 has affected the volatility of the underlying asset. To study this effect, several models and approaches are used such as the GARCH process and others models and approaches formulated by several academics who studied this issue for other underlying spot markets
Arterial transfer functions: background, applications and reservations.

Use of arterial transfer functions in modern medicine stems from the pioneering work of McDonald, Taylor and Womersley in London’s St Bartholomew’s Hospital in the 1950s. Womersley [1], an applied mathematician, showed that the nonlinearities in the equations of motion for fluid in elastic tubes were sufficiently small to be neglected to a first approximation. McDonald and Taylor [2], with the benefit of this background, expressed pressure and flow waves in the frequency domain, and related corresponding frequency components (harmonics) of pressure and flow waves to describe transfer functions – of pressure and flow at the same site (vascular impedance) – and to describe pressure relationships at different sites (pressure propagation). This concept expanded resistance of a vascular bed (as the ratio of mean pressure/mean flow) and of a mean pressure gradient along a segment or network of arteries, so that other arterial properties including elasticity, momentum and wave reflection could be embraced together with vascular resistance [3–6].
Health‐related quality of life in children with sickle cell disease: child and parent perception

Health‐related quality of life (HRQL) is an outcome that may be used to measure the impact of sickle cell disease on the child and their family but has not been routinely assessed in this disease. The objective of this study was to describe the HRQL of children with sickle cell disease as reported by the parent and the child, to compare the relationship between the two, and to determine the association of parent, child and disease characteristics on HRQL. Ninety‐five parents completed the Child Health Questionnaire (CHQ)‐Parent Form28 and 53 children completed the CHQ‐Child Form87. Compared with the child report, parents reported worse HRQL in the overall perception of health, physical functioning, behaviour and self esteem domains of HRQL (P < 0·005). Parent and child reports of HRQL correlated strongly in assessment of the impact of bodily pain (r = 0·58) on HRQL and moderately in physical functioning (r = 0·44), behaviour (r = 0·45), general health (r = 0·44), self esteem (r = 0·40) and changes in health (r = 0·33) domains. Disease status, neurobehavioral co‐morbidities, and parent education were associated with the HRQL of the child. Both the parent and child perspectives are needed to fully understand the impact of sickle cell disease on the HRQL of the child and effect of this disease on the family.
Remote-controlled platoon merging via coder-estimator sequence algorithm for a communication network

In this paper, a platoon-merging control system is considered as a remotely located system with a state represented by a stochastic process. In this system, it is common to encounter situations where a single decision maker controls a large number of subsystems, and observation and control signals are sent over a communication channel with finite capacity and significant transmission delays. Unlike a classical estimation problem where the observation is a continuous process corrupted by additive noise, there is a constraint that the observation must be coded and transmitted over a digital communication channel with finite capacity. A recursive coder-estimator sequence is a state estimation scheme based on observations transmitted with finite communication capacity constraint. In this paper, we introduce a stochastic model for the lead vehicle in a platoon of vehicles in a lane considering the angle between the road surface and a horizontal plane as a stochastic process. In order to merge two platoons, the lead vehicle of the following platoon is controlled by a remote control station. Using the coder-estimator sequence, the remote control station designs the feedback controller. The simulation results show that the inter-vehicle distance and the deviation from the desired inter-vehicle distance are well regulated.
Alignment Distances on Systems of Bags

Recent research in image and video recognition indicates that many visual processes can be thought of as being generated by a time-varying generative model. A nearby descriptive model for visual processes is thus a statistical distribution that varies over time. Specifically, modeling visual processes as streams of histograms generated by a kernelized linear dynamic system turns out to be efficient. We refer to such a model as a system of bags. In this paper, we investigate systems of bags with special emphasis on dynamic scenes and dynamic textures. Parameters of linear dynamic systems suffer from ambiguities. In order to cope with these ambiguities in the kernelized setting, we develop a kernelized version of the alignment distance. For its computation, we use a Jacobi-type method and prove its convergence to a set of critical points. We employ it as a dissimilarity measure on Systems of Bags. As such, it outperforms other known dissimilarity measures for kernelized linear dynamic systems, in particular the Martin distance and the Maximum singular value distance, in every tested classification setting. A considerable margin can be observed in settings, where classification is performed with respect to an abstract mean of video sets. For this scenario, the presented approach can outperform the state-of-the-art techniques, such as dynamic fractal spectrum or orthogonal tensor dictionary learning.
Capacity Scaling Laws in Interference-Limited Multiple-Antenna AF Relay Networks With User Scheduling

The ergodic capacity of multiuser multiple-antenna amplify and forward relay networks with co-channel interference is investigated. Notwithstanding the system complexity, the proposed capacity analysis framework was made possible owing to the newly found complementary moment generating function transform. First, the exact expression for the ergodic capacity, under interference-aware opportunistic scheduling and Rayleigh fading, is derived for finite antenna and user counts. In addition, using extreme value theory, closed-form expressions for the asymptotic ergodic rates are derived for an unlimited number of users or/and antennas at the source. The large-scale analysis embodies, through new insightful formulas, common popular observations so far disclosed intuitively or empirically. Capitalizing on these novel scaling laws, we have been able to derive new closed-form expressions for capacity losses due to intercell interference at the relay and all users. Simulation results suggest a rather fast convergence of the capacity gains to the new asymptotic limits, thereby demonstrating the practical importance of our novel scaling results.
A qualitative study about the effects of Transport Information Systems on the insurance premiums for haulage companies

The last decades the information technology has invaded our society and affected the way we live our lives. In recent years it has also reached the vehicle industry. A tougher competition in the automotive business is driving on the development of IT. The Automotive companies are looking for new ways of differentiate against their customers. IT is a powerful tool to improve the car. The haulage companies have generally low margins, and the need of a more effective transport is getting more obvious. The need of lower fuel consumption, lower communication costs and a more effective rout planning is needed. Transport Information System has been more common in the commercial traffic. The system is used for dynamic navigation – to find the fastest way, to get continuous serviced, to control security systems like brakes, to get detailed information about fuel consumptions and optimize driving behaviour, all of this gives more effective transports. New technology such as GPS and telematics allows for new value propositions in the insurance industry context. In particular the new way of information gathering on risk relevant parameters, through the use of active and passive tags, GPS and telematic leads to these changes, with more accurate information available to insurance companies. They can use this additional information for risk evaluation, dynamic pricing and insurance product customization. This study focus on haulage companies and Transport Information Systems, we will investigate if haulage companies that have a TIS system can get a lower insurance premium. The purpose is to investigate how both insurance companies and haulage companies can benefit from this technique. Such work has not yet been thoroughly examined; therefore we saw a good opportunity to investigate it.
