Integer-Forcing Source Coding

Integer-Forcing (IF) is a new framework, based on compute-and-forward, for decoding multiple integer linear combinations from the output of a Gaussian multiple-input multiple-output channel. This paper applies the IF approach to arrive at a new low-complexity scheme, IF source coding, for distributed lossy compression of correlated Gaussian sources under a minimum mean squared error distortion measure. All encoders use the same nested lattice codebook. Each encoder quantizes its observation using the fine lattice as a quantizer and reduces the result modulo the coarse lattice, which plays the role of binning. Rather than directly recovering the individual quantized signals, the decoder first recovers a full-rank set of judiciously chosen integer linear combinations of the quantized signals, and then inverts it. In general, the linear combinations have smaller average powers than the original signals. This allows to increase the density of the coarse lattice, which in turn translates to smaller compression rates. We also propose and analyze a one-shot version of IF source coding that is simple enough to potentially lead to a new design principle for analog-to-digital converters that can exploit spatial correlations between the sampled signals.
Combined effects of some chemicals on beta–galactosidase activity using a new semiparametric error in variables model

The combined effects of some chemicals on β–galactosidase activity by Anoxybacillus sp. FMB1 were studied using semiparametric errors in variables methodology when the error has an unknown distribution. An experimental design was chosen to explain six chemicals, dithiothreitol (DTT), phenylmethylsulfonyl fluoride (PMSF), N–ethylmaleimide (NEM), iodoacetamide (Iod A), –Mercaptoethanol (β–Mer) and 1,10–phenanthroline (phen) and to investigate the results. This technique constrained the number of real experiments performed while considering conceivable interactions between six chemicals. The optimal combinations of chemical concentration for maximum β–galactosidase activity was determined as 8 mM DTT, 8 mM PMSF, 8 mM NEM, 8 mM Iod A, 2 mM β–Mer and 2 mM phen. We also compared the no measurement error case and errors in variables case. The proposed estimator shown has better performances.

Modeling of Longitudinal Pulse Rate, Respiratory Rate and Blood Pressure Measurements from Congestive Heart Failure Patients under Follow Up at Tikur Anbessa Specialized Hospital

Congestive heart failure (CHF) is a chronic condition that happens when the heart’s muscle becomes too damaged to adequately pump the blood around your body. The main objective of this study was to modeling the longitudinal pulse rate, respiratory rate and blood pressure measurements from congestive heart failure patients under follow up at Tikur Anbessa Specialized Hospital. This retrospective cohort study was based on secondary data obtained from Tikur Anbessa Specialized Hospital. Modeling approach of longitudinal data analysis was applied by suing Linear Mixed Models to identify risk factors and to compare efficiency of the models. Fit statistics showed that the joint model resulted in better fit to the data than the separate models, implying a significant association among the two end points. Based on the joint model for SBP, diagnosis history, family history, NYHA class, and time, and for DBP, age, weight, sex, family history, NYHA class, and time are the significant factors, at 5% level of significance. The joint model fitted the data better than the separate models. The result from the joint model suggested a strong association between the evolutions and a slowly increasing evolution of the association between PR and RR also, between SBP and DBP. Thus, fitting joint model is recommended for researches to any types of multivariate response variable together jointly.
Cognitive and spectral coherence of EEG alterations in resting state in children with chronic TBI

Introduction. TBI is associated with alterations in cortico-subcortical connectivity. However, little attention has been paid to its clinical characteristics and functional connectivity in pediatric patients with chronic TBI. Objective. To evaluate the cognitive performance and spectral coherence of a group of children with TBI in non-acute phase. Method. Cross-sectional study of 15 children with chronic TBI and 17 healthy children. The Neuropsychological Assessment of Children (Evaluación Neuropsicológica Infantil, ENI) was used and the resting activity of the EEG with eyes-closed was recorded. Offline, two-second epochs of the EEG of each participant were chosen and the spectral coherence was estimated in a range of 1.6 to 30 Hz. The cognitive performance between groups was compared with T-test/Mann-Whitney U Test and MANOVA for the coherence values. Results. The TBI group showed a lower performance (p ≤ 0.05) in metalinguistic, visuospatial skills, attention, memory, non-verbal flexibility, planning, and organization. Differences (p ≤ 0.000) were found both inter and intrahemispherically in the spectral coherence between the groups, particularly on F1-F3 (95% CI: 0.543 - 0.557) over the whole frequency range and F3-C3 (95% CI: 0.503 - 0.515) in delta, theta, alpha2, and beta frequencies. Discussion and conclusión. Our findings suggest alterations of hypo and hyper functional connectivity, particularly on the frontal and parietal lobes of both hemispheres, even after several years of a TBI. It is possible that a subtle difference in the degree of connectivity is crucial in the genesis or successful development of attentional, mnesic, executive, and visuospatial processes.

Two major themes were identified: 1) content of interaction and 2) outcomes from the interventions. Six sub-themes were identified. The results provided a unique insight into the psycho-emotional impact of storytelling interventions. Conclusions: It is essential that health care professionals understand the core benefits of storytelling for people with cancer. Further interventions are needed to identify an approach which could be applied within clinical settings.
Tomorrow's fish and chip paper? Slowly incorporated news and the cross-section of stock returns

ABSTRACT The link between news and investor decision making is widely discussed in the literature. Utilising unique U.S. firm-level news data between 1979 and 2016, we document a cross-sectional difference in the speed of the diffusion of information contained in news. We distinguish news articles as being either slowly or quickly incorporated into contemporaneous stock prices. The return spread between stocks classified according to these two types of news yields a statistically significant profit of 139 basis points per month. This abnormal return cannot be explained by other well-known risk factors and is robust when allowing for trading costs. Overall, our research refines the role of news regarding information dissemination in the financial markets.

Rabi Resonances in Buffer-Gas-Filled Cs-Vapor Cells for SI-Traceable Microwave Magnetic Field Detection

We describe a microwave (MW) magnetic-field detection technique based on the Rabi resonance of a Cs-buffer gas vapor cell. Inside the vapor cell, alkali atoms interact with MWs radiated from an antenna through an open-ended rectangular waveguide. We obtained the Rabi resonance line shape, which determines precisely the Rabi frequency of the MW magnetic field with a phase modulation frequency. For various vapor cells, a detailed characterization of several experimental parameters and a theoretical analysis were performed. The optimal laser intensity and the cell temperature that maximize the Rabi resonance amplitude are obtained. Moreover, the cell-temperature-based frequency shift of the Rabi resonance was investigated. These experimental results are important in developing future International System of Units-traceable MW magnetic field sensors and an MW power standard.

Effect of dynamic and static strength training using Thera-Band® on elite athletes muscular strength

Background and Study Aim: Many training scientists have concentrated on alternative models and materials to find the most efficient way to develop the strength for the last few decades. Thera-Band® is an alternative training tool used to enhance some motoric characteristics (flexibility and strength) by the athletes. The aim of the study is the knowledge about the effects of dynamic and static strength exercises when applied with Thera-Band® on the athlete’s strength indicators. Material and Methods: Twenty boxers, at an elite level, participated the research and were divided into two groups varied as dynamic and static exercise, thus they were exposed to dynamic and static contraction force exercises with TheraBand® for 8 weeks, 3 days a week. BMI, hand claw strength and back-leg strength tests were performed in the pre-and post-training processes. Results: A significant increase was encountered in all kinds of strength measurements for the dynamic strength group at the end of the first training (p<0.05) after the applications for the eight weeks. Significant increases were seen in the athletes performing static strength training in their left-hand claw, back-leg and leg strength values. In comparing the general performances of the athletes, the results showed that there was not any, significant differences between the two participant groups. Conclusions: Especially in the sports branches, in which the strength is crucial, it was determined that the strength might increase in dynamic and static applications by determining the training with right resistance levels with the Thera-Band®, which has increasing popularity nowadays. From this point, it can be expressed that TheraBand® exercises can be used not only for rehabilitation purposes but also to increase the strength of the athletes performing performance sports.
Purification and characterization of -amylase produced by Penicillium citrinum HBF62

The extracellular amylase produced by Penicillium citrinum HBF62 was purified 18 folds using starch affinity chromatography. The molecular weight of amylase was estimated to be about 65 kDa by SDS-PAGE. The temperature and pH for optimum activity of the enzyme were 55°C and 5.5, respectively. It was thermostable between 27 and 60°C and retained more than 50% activity after 24 h at these temperatures. It was found to be stable pH range between 3.5 and 8.5. Km and Vmax values for soluble starch of the enzyme were calculated to be 0.2 mg/ml and 5000 U/mg protein, respectively. The amylase exhibited broad substrate specificity because it acted on all the substrates tested. While the enzyme was activated by Mn2+, Ca2+, Co2+, Fe3+, Ba2, NH4+ and Al3+, the other ions and EDTA had no effect on its activity. The enzyme activity was inhibited in the presence of phenylmethanesulfonylfluoride (PMSF), N-bromosuccinimide (NBS) and 1-cyclohexyl-3-(2-morpholinyl-4-ethyl) carbodiimide methyl p-toluenesulphonate (CMC), suggesting that serine, tryptophan residues and carboxyl groups play an important role in the catalytic process. The activity of amylase was found to be tolerant up to 5 M NaCl concentration. Raw corn starch adsorption of amylase was found to be 74%. Thin layer chromatography of the starch hydrolysis products showed glucose and maltose as the main end products, indicating that the purified enzyme was α-amylase. Key words: Penicillium citrinum, α-amylase, purification, characterization.

Nature-based recreation associated with connectedness to nature and leisure satisfaction among students in Brazil

ABSTRACT There is growing evidence that nature-based recreation (NBR) during childhood promotes connectedness to nature, which in turn fuels NBR during adulthood. In addition to providing a number of health benefits, NBR participation may enhance leisure satisfaction, an important predictor of happiness and life satisfaction. In this exploratory study, we tested these hypothesised links using a path model with a cross-sectional sample of 224 Brazilian college students, where NBR participation during childhood increases connectedness to nature and NBR participation during adulthood, which in turn promotes leisure satisfaction. The model fit the data well χ2 (2) = 1.924, χ2/df = 0.962 (N = 220, p = .38), CFI = 1.00, AGFI = . 978, GFI = . 996, and RMSEA = . 00, with results showing an indirect positive link between NBR during childhood and leisure satisfaction, and a direct link between NBR during adulthood and leisure satisfaction. The indirect effect of connectedness to nature on leisure satisfaction was also significant: NBR during childhood fostered connectedness to nature, which motivated NBR during adulthood and higher levels of leisure satisfaction. Leisure practitioners can improve people’s leisure satisfaction by promoting engagement in NBR activities across life stages and emphasising connection to nature.
Identification of potential genomic regions and candidate genes for egg albumen quality by a genome-wide association study

Abstract Albumen quality is a leading economic trait in the chicken industry. Major studies have paid attention to genetic architecture underlying albumen quality. However, the putative quantitative trait locus (QTL) for this trait is still unclear. In this genome-wide association study, we used an F2 resource population to study longitudinal albumen quality. Seven single-nucleotide polymorphism (SNP) loci were found to be significantly (p<8.43×10-7) related to albumen quality by univariate analysis, while 11 SNPs were significantly (p<8.43×10-7) associated with albumen quality by multivariate analysis. A QTL on GGA4 had a pervasive function on albumen quality, including a SNP at the missense of NCAPG, and a SNP at the intergenic region of FGFPB1. It was further found that the putative QTLs at GGA1, GGA2, and GGA7 had the strongest effects on albumen height (AH) at 32 weeks, Haugh units (HU) at 44 weeks, and AH at 55 weeks. Moreover, novel SNPs on GGA5 and GGA3 were associated with AH and HU at 32, 44, and 48 weeks of age. These results confirmed the regions for egg weight that were detected in a previous study and were similar with QTL for albumen quality. These results showed that GGA4 had the strongest effect on albumen quality. Only a few significant loci were detected for most characteristics probably reflecting the attributes of a pleiotropic gene and a minor-polygene in quantitative traits.
The Effect of Personality Traits on Employee Job Satisfaction with Moderating Role of Islamic Work Ethics

Personality factors and ethical values are considered as vital element in social and professional life. This present research aims to explore the relationship between Personality and Job Satisfaction. Further, we tried to test the moderating effect of Islamic work ethics ( IWE ) in the relationship of Personality traits with Job satisfaction. Convenience sampling was used in defining sample as in Pakistan there is no data base which provides information regarding number of employees. Due to moderating variable the data has been collected from respondents who identify themselves as Muslim. To collect data from respondents Self-administered, close-ended questionnaires and e-questionnaire were used in this study and respondents were targeted in the normal working environment. Correlation and regression analysis was used to analyze the data statistically. The results of study indicated that neuroticism exhibits significant negative effect on job satisfaction. Also, openness to experience, agreeableness and conscientiousness showed positive effect on job satisfaction. Whereas, extraversion exhibits no effect on job satisfaction and IWE has a negative effect on job satisfaction. However, the output indicates that IWE do not act as moderator in the relation of agreeableness and conscientiousness with job satisfaction moderation effect of IWE is observed between the relationship of neuroticism, extraversion and openness to experience with job satisfaction.
Derivation of Systolic Programs

We describe a methodology for mapping linear recurrence equations to a spectrum of systolic architectures. First, we design a systolic program in a very general architecture referred to as Basic Systolic Architecture and establish the correctness of the implementation. Next, we show how efficient transformations/implementations of programs for different systolic architectures can be obtained through transformations such as projections and translations.
Proportional Fairness for EV Charging in Overload

This paper studies a charging facility for electrical vehicles (EVs) at a parking garage, under the assumption that the infrastructure has a limited power capacity. In situations of overload, scheduling decisions must be made on which EVs to charge, possibly taking into account users’ sojourn times. We propose a fluid model that tracks service and sojourn times for a large population, enabling analytical studies of the distribution of service in steady state, for different policies. These results raise the issue of fairness in the distribution of partial service. We introduce a new policy called least laxity ratio to achieve a suitable notion of proportional fairness. We test our results in simulation, including a real data-set with time-varying load. Our results show that our conclusions remain valid in this scenario, in particular the proposed policy performs well under an objective empirical measure of fairness.
An Analysis of Intercultural Students’ Self-Determination in Graduate Online Programmes: Implications for Praxis

Abstract The self-determination of online graduate students was studied in terms of the impact of autonomy, competence and relatedness upon their persistence. Unique to this study was the assessment of the potential influence of socio-cultural factors. As the majority of research into online university students’ persistence is generated from the US, Canada, UK and European countries assessing their own domestic populations, the global nature of this study provides a new perspective. Fifty-four online graduate students representing 26 countries participated representing 19 lesser developed economies and 7 developed economies. Collectivist versus individualistic cultures were equally represented. Self-determination Theory (SDT) was examined both in terms of the online classroom environment as well as overcoming life challenges for programme perseverance. A correlational matrix was used to reject the null hypothesis. Results indicated that statistically significant correlations exist among the three variables, and, in the instances of the variables of autonomy and relatedness, a significant negative correlation exists. The findings indicate that the participants displayed strong internal locus of control, self-directed learning, competency and relatedness in attaining success within the online environment programme. Cultural communitarianism values were not found to be of significant influence.
