Secrecy Analysis of Amplify-and-Forward Relay Networks with Beamforming

This paper analyzes the secrecy performance of an amplify-and-forward (AF) relay network, where a multi-antenna eavesdropper attempts to overhear the transmitted message from a multi-antenna source to a multi-antenna destination with a single antenna relay. Firstly, we derive the approximate analytical expressions for the secrecy outage probability (SOP) and average secrecy rate (ASR) of the relay network. Then, asymptotic expressions of SOP and ASR at high main-to-eavesdropper ratio (MER) are also provided to reveal the diversity gain of the secure communication. Finally, numerical results are given to verify the theoretical analysis and show the effect of the number of antennas in the considered relay network.
The Relationship between Organizational Trust, OCB and Performance of Faculty of Physical Education

Exercise is a socio-cultural phenomenon, which is a dynamic alliance of social institutions. It should be considered as part of the formal requirements of the population. The purpose of this study is to determine the relationship between organizational trust, organizational citizenship behavior (OCB) and performance of Physical Education teachers in Islamic Azad University of Rasht in Iran. The aim of this study is to be applied, and the methods are descriptive and correlational research. The method of data collection is a fieldwork one. The population of the study consisted of all Physical Education Faculty in Islamic Azad University of Rasht (n=20). Samples were selected and considered. Data tools are questionnaires. The organizational trust used Chia and Yoo questionnaire by modifying Moghimi and Ramazan (2011). To measure OCB a Podsakoff questionnaire was used. To measure organizational performance, Hersey and Goldsmit questionnaire was used. The descriptive statistics were used to calculate the central tendency and dispersion. Inferential statistics were used to determine the KS test for normal data. Pearson's test was conducted to investigate the correlation with the software SPSS 20. The results showed that there was a significant relationship between organizational trust and OCB (r= 0/37), and between organizational trust and organizational performance (r=0/76), as well as between the OCB and organizational performance of Physical Education teachers (r=0/40), in Islamic Azad University of Rasht (P< 0/05).
Extracellular Water/Intracellular Water Is a Strong Predictor of Patient Survival in Incident Peritoneal Dialysis Patients

Background: The mortality rate of peritoneal dialysis (PD) patients is still high and controversies persist regarding the mortality predictor. This study was designed to identify the predictability of the extracellular water/intracellular water ratio (E/I) on mortality in PD patients. Methods: 227 incident PD patients were included. Time-dependent Cox proportional hazard regression was used to investigate the predictability of E/I on mortality. Results: The 2- and 3-year survival was 74 and 65%, respectively. Univariate Cox proportional hazard regression analysis showed that the significant predictors of mortality were age, sex, Charlson Comorbidity Index, total Kt/V, serum albumin, pulse pressure, presence of malnutrition, and E/I. However, the final Cox proportional hazard models revealed that E/I was the only significant predictor. For every increase of 0.1 in the E/I value, the relative risk of death was 1.368. Conclusions: E/I is a strong independent predictor of mortality in incident PD patients.
Two Steps Forward, One Step Back.

There is much to like in Campos et al.’s (this issue) comprehensive and thoughtful target article on the psychological changes impelled by the onset of self-produced locomotion. The critical role of motor abilities in development is reestablished in the midst of an era preoccupied with infants’ precocious worldly knowledge and children’s emerging theories of mind. The complexity, indirectness, and nonlinearity of development are also wonderfully illustrated. Who would have thought that crawling promotes the understanding of referential gestures, until Campos et al. point out an obvious connection via the increase in parents’ distal prohibitions and commands? The article also draws on a wealth of evidence, showcasing all of the classic methodologies in developmental psychology, from deprivation designs and parent interviews to animal models and cross-cultural comparisons. It will be a terrific article to teach from in methods and design courses. Along with its many virtues, however, Campos et al.’s strong emphasis on locomotor experience as an agent of change seems to sharpen several distinctions that developmental psychologists have been working hard to blur. The first of these is the well-known “nature versus nurture” dichotomy, once the reason for and now the bane of the discipline’s existence. Early in the article, Campos et al. state their aim of showing that the broad-scale transition in infancy involving search for hidden objects, secondary intersubjectivity, reactions to heights, and so forth “is not necessarily mediated by maturational factors (i.e., by the unfolding of a genetic blueprint for psychological changes), but instead, is intimately linked to experience” (pp. 153–154). They go on to argue persuasively that these diverse cognitive and social acquisitions are related to experiences and attentional biases that in turn are the inevitable consequences of self-produced locomotion. Hence, once an indiINFANCY, 1(2), 225–230 Copyright © 2000, Lawrence Erlbaum Associates, Inc.
Portunes: generating attack scenarios by finding inconsistencies between security policies in the physical, digital and social domain

An input stage of a police radar detector is configured so that a near end of a mixer is coupled to an antenna for receiving high frequency signals and a far end of the mixer is coupled to the antenna for receiving low frequency signals. A local oscillator and an intermediate frequency amplifier are also coupled to the far end of the mixer. The low frequency signals, X band police radar signals, are coupled to the far end of the mixer through a band rejection filter, which serves as a diplexer, a preamplifier and a first bandpass filter. The local oscillator is coupled to the far end of the mixer through a second bandpass filter and the far end of the mixer is coupled to the intermediate frequency amplifier through a low pass filter. The high frequency signals, K band and Ka band signals, are coupled to the near end of the mixer from the antenna through a high pass filter. The diplexer in combination with the first and second bandpass filters, the low pass filter and the high pass filter passively multiplex the related signals within the input stage of the police radar detector.
Improving summarization through rhetorical parsing tuning

We study the relationship between the structure of discourse and a set of summarization heuristics that are employed by current systems. A tight coupling of the two enables us to learn genre-speciﬁc combinations of heuristics that can be used for disambiguationduring discourse parsing. The same coupling enables us to construct discourse structures that yield summaries that contain textual units that are not only important according to a variety of position, title, and lexical-similarity-based heuristics, but also central to the main claims of texts. A careful analysis of our results enables us to shed some new light on issues related to summary evaluation and learning
Spectrally Efficient Variable-Rate Best-Relay Selection Scheme for Adaptive Cooperative System

In this paper, we introduce an adaptive cooperative system that selects the best relay among the available relay nodes to cooperate with a source node for transmitting the information signal to a destination node if the spectral efficiency can be maximized. This maximization is achieved as long as the average bit error rate is below a target level. The channels are modeled as independent and identically distributed Rayleigh fading channels over the relay nodes, and not identically distributed over the relay hops. Closed-form expressions for the average spectral efficiency and the average bit error rate are derived when adaptive discrete rate M-QAM is used as a practical implementation of the variable-rate transmission. Simulation results show that the proposed scheme, compared with the opportunistic amplify-and-forward fixed relaying and the conventional direct transmission, can provide the maximum average spectral efficiency and perfectly maintain the average bit error rate.
The Role of Autophagy in Age-Related Neurodegeneration

Most age-related neurodegenerative diseases are characterized by accumulation of aberrant protein aggregates in affected brain regions. In many cases, these proteinaceous deposits are composed of ubiquitin conjugates, suggesting a failure in the clearance of proteins targeted for degradation. The 2 principal routes of intracellular protein catabolism are the ubiquitin proteasome system and the autophagy-lysosome system (autophagy). Both of these degradation pathways have been implicated as playing important roles in the pathogenesis of neurodegenerative disease. Here we describe autophagy and review the evidence suggesting that impairment of autophagy contributes to the initiation or progression of age-related neurodegeneration. We also review recent evidence indicating that autophagy may be exploited to remove toxic protein species, suggesting novel strategies for therapeutic intervention for a class of diseases for which no effective treatments presently exist.
Reconstructing Viral Genomes from the Environment Using Fosmid Clones: The Case of Haloviruses

Background Metaviriomes, the viral genomes present in an environment, have been studied by direct sequencing of the viral DNA or by cloning in small insert libraries. The short reads generated by both approaches make it very difficult to assemble and annotate such flexible genomic entities. Many environmental viruses belong to unknown groups or prey on uncultured and little known cellular lineages, and hence might not be present in databases. Methodology and Principal Findings Here we have used a different approach, the cloning of viral DNA into fosmids before sequencing, to obtain natural contigs that are close to the size of a viral genome. We have studied a relatively low diversity extreme environment: saturated NaCl brines, which simplifies the analysis and interpretation of the data. Forty-two different viral genomes were retrieved, and some of these were almost complete, and could be tentatively identified as head-tail phages (Caudovirales). Conclusions and Significance We found a cluster of phage genomes that most likely infect Haloquadratum walsbyi, the square archaeon and major component of the community in these hypersaline habitats. The identity of the prey could be confirmed by the presence of CRISPR spacer sequences shared by the virus and one of the available strain genomes. Other viral clusters detected appeared to prey on the Nanohaloarchaea and on the bacterium Salinibacter ruber, covering most of the diversity of microbes found in this type of environment. This approach appears then as a viable alternative to describe metaviriomes in a much more detailed and reliable way than by the more common approaches based on direct sequencing. An example of transfer of a CRISPR cluster including repeats and spacers was accidentally found supporting the dynamic nature and frequent transfer of this peculiar prokaryotic mechanism of cell protection.
The Representation of Masculinity in Mama Lemon Advertisement Supermarket Version

It has been a general consent within society that masculinity is a term for men and femininity is a term for women. In traditional gender roles, it may simply be thought that masculine is not doing feminine things. As a result, it evokes binary opposition between men and women position. Men has long been seen as the dominant. However, today, the notion of gender equality rises in our life. Men and women are then thought as equal genders.Thus, masculinity poses equal position to femininity. This idea is portrayed in Indonesia, particularly by the male model of one of the Mama Lemon television advertisements. This study aims to examine the representation of masculinity in Mama Lemon television advertisement. With the application of Goffman’s pattern of gender portrayal in advertisements, this study found 12 scenes as the primary data. The selected scenes are then analysed by using The Theory of New Man and Hegemonic Masculinity to find whether the portrayal of masculinity in the male model of Mama Lemon advertisement is different from the traditional gender role. The finding shows that there are some changes in the pattern of gender portrayal in the representation of masculinity in the male model of Mama Lemon advertisement. However, these changes do not alter the idea of traditional gender role which regards men as more superior. Instead, these changes are portrayed to reinforce the domination of men.
Formative assessment and self‐regulated learning: a model and seven principles of good feedback practice

The research on formative assessment and feedback is reinterpreted to show how these processes can help students take control of their own learning, i.e. become self‐regulated learners. This reformulation is used to identify seven principles of good feedback practice that support self‐regulation. A key argument is that students are already assessing their own work and generating their own feedback, and that higher education should build on this ability. The research underpinning each feedback principle is presented, and some examples of easy‐to‐implement feedback strategies are briefly described. This shift in focus, whereby students are seen as having a proactive rather than a reactive role in generating and using feedback, has profound implications for the way in which teachers organise assessments and support learning.
Antipsychotic polypharmacy trends among Medicaid beneficiaries with schizophrenia in San Diego County, 1999-2004.

OBJECTIVE This study examined trends and costs of second-generation antipsychotic polypharmacy among Medicaid beneficiaries with schizophrenia in San Diego County. METHODS Medicaid data were used to identify 15,962 persons with schizophrenia receiving antipsychotic medications between 1999 and 2004. The yearly proportion of beneficiaries receiving second-generation antipsychotic polypharmacy, duration of polypharmacy, inpatient admissions, and pharmaceutical costs were examined. RESULTS The proportion of clients receiving second-generation antipsychotic polypharmacy increased from 3.3% in 1999 to 13.7% in 2004, whereas annual antipsychotic medication costs increased from $4,128 to $5,231 (2004 dollars). Among those receiving second-generation polypharmacy, the percentage receiving second-generation polypharmacy for 12 months increased from 5.1% to 14.4%, and the percentage hospitalized increased from 7.2% to 9.0%. CONCLUSIONS The prevalence of long-term second-generation antipsychotic polypharmacy and its associated costs increased substantially between 1999 and 2004. Prescribing antipsychotic polypharmacy is an unproven and costly strategy that if left unchanged could lead to administrative efforts to cut costs and dictate practice.
Multiple Gaussian Process Models

We consider a Gaussian process formulation of the multiple kernel learning problem. The goal is to select the convex combination of kernel matrices that best explains the data and by doing so improve the generalisation on unseen data. Sparsity in the kernel weights is obtained by adopting a hierarchical Bayesian approach: Gaussian process priors are imposed over the latent functions and generalised inverse Gaussians on their associated weights. This construction is equivalent to imposing a product of heavy-tailed process priors over function space. A variational inference algorithm is derived for regression and binary classification.
Discovering Support and Affiliated Features from Very High Dimensions

In this paper, a novel learning paradigm is presented to automatically identify groups of informative and correlated features from very high dimensions. Specifically, we explicitly incorporate correlation measures as constraints and then propose an efficient embedded feature selection method using recently developed cutting plane strategy. The benefits of the proposed algorithm are two-folds. First, it can identify the optimal discriminative and uncorrelated feature subset to the output labels, denoted here as Support Features, which brings about significant improvements in prediction performance over other state of the art feature selection methods considered in the paper. Second, during the learning process, the underlying group structures of correlated features associated with each support feature, denoted as Affiliated Features, can also be discovered without any additional cost. These affiliated features serve to improve the interpretations on the learning tasks. Extensive empirical studies on both synthetic and very high dimensional real-world datasets verify the validity and efficiency of the proposed method.
Le suicide chez l'adolescent

Apres 1 500 deces annuels, le suicide est la deuxieme cause de deces chez les sujets de 15 a 24 ans. Sur le plan epidemiologique, il existe une augmentation nette de prevalence du suicide dans cette tranche d'âge, avec une predominance feminine des tentatives de suicide, mais une plus forte mortalite des gestes chez le garcon. Les gestes suicidaires chez l'adolescent sont caracterises par leur impulsivite tres importante et leur rythmicite (periode scolaire, periode de l'annee). Les facteurs de risque suicidaire sont nombreux. L'existence d'un trouble psychiatrique demeure le facteur principal, notamment les troubles depressifs ou les troubles des conduites et plus encore leur association. Parmi les autres facteurs, il faut relever chez l'adolescent le role des evenements familiaux et environnementaux, notamment les phenomenes d'imitation. Ces differents facteurs de risque s'articulent ensemble pour constituer des modeles dynamiques de suicide. Leur role peut etre different en fonction du sexe. La dangerosite du suicide chez l'adolescent ne doit pas etre sous-estimee, comme cela a pu etre le cas particulierement du fait de la frequence de ces tentatives. Ceci est particulierement vrai si l'on considere la frequence d'environ 50 % des recidives. Ces donnees soulignent l'importance de l'evaluation systematique de tout adolescent suicidant et portant notamment sur la recherche de manifestations depressives ou de conduites agressives et delinquantes et l'importance de strategies de prevention.
Summarisation based on Human Language Technologies and its Applications

The research work carried out in this thesis focuses on Text Summarisation, proposing and developing compendium Text Summarisation tool. This tool takes into account the cognitive perspective, that provides insights of how humans summarise, as well as computational issues needed for its automation. For evaluating compendium, we selected different corpora belonging to a wide range of domains and textual genres. Moreover, we also performed an extrinsic evaluation, applying compendium to three Human Languages Technologies tasks: question answering, opinion minng and text classification. The results obtained show that the generated summaries are very appropriate both for individual users as well as for other Human Language Technologies applications.
FOLFIRINOX versus gemcitabine for metastatic pancreatic cancer.

BACKGROUND Data are lacking on the efficacy and safety of a combination chemotherapy regimen consisting of oxaliplatin, irinotecan, fluorouracil, and leucovorin (FOLFIRINOX) as compared with gemcitabine as first-line therapy in patients with metastatic pancreatic cancer. METHODS We randomly assigned 342 patients with an Eastern Cooperative Oncology Group performance status score of 0 or 1 (on a scale of 0 to 5, with higher scores indicating a greater severity of illness) to receive FOLFIRINOX (oxaliplatin, 85 mg per square meter of body-surface area; irinotecan, 180 mg per square meter; leucovorin, 400 mg per square meter; and fluorouracil, 400 mg per square meter given as a bolus followed by 2400 mg per square meter given as a 46-hour continuous infusion, every 2 weeks) or gemcitabine at a dose of 1000 mg per square meter weekly for 7 of 8 weeks and then weekly for 3 of 4 weeks. Six months of chemotherapy were recommended in both groups in patients who had a response. The primary end point was overall survival. RESULTS The median overall survival was 11.1 months in the FOLFIRINOX group as compared with 6.8 months in the gemcitabine group (hazard ratio for death, 0.57; 95% confidence interval [CI], 0.45 to 0.73; P<0.001). Median progression-free survival was 6.4 months in the FOLFIRINOX group and 3.3 months in the gemcitabine group (hazard ratio for disease progression, 0.47; 95% CI, 0.37 to 0.59; P<0.001). The objective response rate was 31.6% in the FOLFIRINOX group versus 9.4% in the gemcitabine group (P<0.001). More adverse events were noted in the FOLFIRINOX group; 5.4% of patients in this group had febrile neutropenia. At 6 months, 31% of the patients in the FOLFIRINOX group had a definitive degradation of the quality of life versus 66% in the gemcitabine group (hazard ratio, 0.47; 95% CI, 0.30 to 0.70; P<0.001). CONCLUSIONS As compared with gemcitabine, FOLFIRINOX was associated with a survival advantage and had increased toxicity. FOLFIRINOX is an option for the treatment of patients with metastatic pancreatic cancer and good performance status.

The Echinococcus granulosus Antigen B Gene Family Comprises at Least 10 Unique Genes in Five Subclasses Which Are Differentially Expressed

Background Antigen B (EgAgB) is a major protein produced by the metacestode cyst of Echinococcus granulosus, the causative agent of cystic hydatid disease. This protein has been shown to play an important role in modulating host immune responses, although its precise biological function still remains unknown. It is generally accepted that EgAgB is comprised of a gene family of five subfamilies which are highly polymorphic, but the actual number of genes present is unknown. Methodology/Principal Findings Based on published sequences for the family, we designed specific primers for each subfamily and used PCR to amplify them from genomic DNA isolated from individual mature adult worms (MAW) taken from an experimentally infected dog in China and individual larval protoscoleces (PSC) excised from a single hydatid cyst taken from an Australian kangaroo. We then used real-time PCR to measure expression of each of the genes comprising the five EgAgB subfamilies in all life-cycle stages including the oncosphere (ONC). Conclusions/Significance Based on sequence alignment analysis, we found that the EgAgB gene family comprises at least ten unique genes. Each of the genes was identical in both larval and adult E. granulosus isolates collected from two geographical areas (different continents). DNA alignment comparisons with EgAgB sequences deposited in GenBank databases showed that each gene in the gene family is highly conserved within E. granulosus, which contradicts previous studies claiming significant variation and polymorphism in EgAgB. Quantitative PCR analysis revealed that the genes were differentially expressed in different life-cycle stages of E. granulosus with EgAgB3 expressed predominantly in all stages. These findings are fundamental for determining the expression and the biological function of antigen B.
Wavelength conversion by four-wave mixing in semiconductor optical amplifiers

Time-resolved spectral analysis is performed on 10 Gb/s signals wavelength converted by four-wave mixing (FWM) in semiconductor optical amplifiers. A pattern-dependent chirp resulting from parasitic gain modulation by the signal is measured and characterized as a function of the converter's pump-to-probe ratio. This chirp is found to be insignificant for pump-to-probe ratios exceeding 9 dB.
