Transmit Antenna Selection for Security Enhancement in MIMO Wiretap Channels

We propose and analyze transmit antenna selection (TAS) to enhance physical layer security in a wiretap channel with NA antennas at the transmitter, NB antennas at the receiver, and NE antennas at the eavesdropper. We focus on the practical scenario where the transmitter does not have any channel state information (CSI) of the eavesdropper's channel. The transmitter selects a single antenna that maximizes the instantaneous signal-to-noise ratio (SNR) at the receiver. The receiver and the eavesdropper employ either maximal-ratio combining (MRC) or selection combining (SC) to combine the received signals. For the proposed protocols, we derive new closed-form expressions for the probability of non-zero secrecy capacity. We consider Nakagami-m fading with non-identical fading parameters of the main channel, mB, and of the eavesdropper's channel, mE. Next, we derive new closed-form expressions for the exact secrecy outage probability, based on which the ε-outage secrecy capacity is characterized. Based on the exact expressions, we derive the asymptotic secrecy outage probability which accurately reveals the secrecy diversity order and the secrecy array gain. We confirm that the proposed protocols achieve identical secrecy diversity orders of NANBmB. An interesting conclusion is reached that this diversity order is independent of NE and mE. Furthermore, we prove that under the proposed protocols, the secrecy outage probability and the ε-outage secrecy capacity improve with increasing NA.
An empirical channel model for Human Body Communication

This paper presents a statistical characterization of one Human Body Communication (HBC) channel model based on empirical data. The measurements which were conducted on a considerable amount of people guarantee the precision of the model. An adequate evaluation about the path loss, delay spread is convenience and appropriate to design the advanced wideband HBC system.
Exponential decay for the growth-fragmentation/cell-division equation

We consider the linear growth-fragmentation equation arising in the modelling of cell division or polymerisation processes. For constant coefficients, we prove that the dynamics converges to the steady state with an exponential rate. The control on the initial data uses an elaborate $L^1$-norm that seems to be necessary. It also reflects the main idea of the proof which is to use an anti-derivative of the solution. The main technical difficulty is related to the entropy dissipation rate which is too weak to produce a Poincar\'e inequality.
Fitting the Person to the Organisation: Examining the Personality-Job Performance Relationship from a New Perspective

The current study represents an attempt to explore personality dispositions and personality process in a P‐O fit context. A total of 227 employees completed self‐report measures of personality and job satisfaction and their supervisors assessed their citizenship behaviours, generic work competencies and overall job performance. The theoretical approach of the cognitive‐affective personality system was adopted in exploring the research questions and discussing the findings, which reinforced the significance of a confirmatory, theory‐based approach in personality testing. The results supported the existence of relationships between personality and job satisfaction but not between personality and the performance‐related variables, although agreeableness and openness to experience were related to performance for occupations involving interpersonal interaction.
Deriving Relationship Between Semantic Models - An Approach for cCSP

Formal semantics offers a complete and rigorous definition of a language. It is important to define different semantic models for a language and different models serve different purposes. Building equivalence between different semantic models of a language strengthen its formal foundation. This paper shows the derivation of denotational semantics from operational semantics of the language cCSP. The aim is to show the correspondence between operational and trace semantics. We extract traces from operational rules and use induction over traces to show the correspondence between the two semantics of cCSP.
Timing of Cord Blood Treatment after Experimental Stroke Determines Therapeutic Efficacy

Embolic stroke is thought to cause irreparable damage in the brain immediately adjacent to the region of reduced blood perfusion. Therefore, much of the current research focuses on treatments such as anti-inflammatory, neuroprotective, and cell replacement strategies to minimize behavioral and physiological consequences. In the present study, intravenous delivery of human umbilical cord blood cells (HUCBC) 48 h after a middle cerebral artery occlusion (MCAo) in a rat resulted in both behavioral and physiological recovery. Nissl and TUNEL staining demonstrated that many of the neurons in the core were rescued, indicating that while both necrotic and apoptotic cell death occur in ischemia, it is clear that apoptosis plays a larger role than first anticipated. Further, immunohistochemical and histochemical analysis showed a diminished and/or lack of granulocyte and monocyte infiltration and astrocytic and microglial activation in the parenchyma in animals treated with HUCBC 48 h poststroke. Successful treatment at this time point should offer encouragement to clinicians that a therapy with a broader window of efficacy may soon be available to treat stroke.
Neutralizing antibody and interferon‐α in cerebrospinal fluids and sera of acute aseptic meningitis

Cerebrospinal fluids (CSFs) and sera from 20 patients with echovirus 30 (E 30) meningitis, 4 patients with enterovirus 71 (EV 71) meningitis, and 5 patients with acute aseptic meningitis (AM) of unknown etiology were investigated at the acute and the convalescent phases of the disease to elucidate the roles of neutralizing antibody (NT) and interferon‐α (IFN‐α) in the central nervous system (CNS) in cases of AM in humans. Viruses were isolated from the CSFs at the acute phase of AM, but not at the convalescent phase. There was a fourfold or greater rise in NT titer between paired sera to E 30 or EV 71 but only a slight rise between paired CSFs. IFN‐α was detected in the CSFs ranging from <10 to 25.5 IU/ml but not in the sera, and the IFN‐α level in the CSF was significantly higher in the acute phase than in the convalescent phase. These results suggest that in cases of acute enteroviral infections in the CNS, NT plays only a small role in the recovery from AM, and IFN‐α plays a direct or indirect role in curbing the local spread of the virus and eliminating the virus from the CNS at the acute phase of AM.
TURBULENT DYNAMOS WITH SHEAR AND FRACTIONAL HELICITY

Dynamo action owing to helically forced turbulence and large-scale shear is studied using direct numerical simulations. The resulting magnetic field displays propagating wave-like behavior. This behavior can be modeled in terms of an αΩ dynamo. In most cases super-equipartition fields are generated. By varying the fraction of helicity of the turbulence the regeneration of poloidal fields via the helicity effect (corresponding to the α-effect) is regulated. The saturation level of the magnetic field in the numerical models is consistent with a linear dependence on the ratio of the fractional helicities of the small and large-scale fields, as predicted by a simple nonlinear mean-field model. As the magnetic Reynolds number (ReM) based on the wavenumber of the energy-carrying eddies is increased from 1 to 180, the cycle frequency of the large-scale field is found to decrease by a factor of about 6 in cases where the turbulence is fully helical. This is interpreted in terms of the turbulent magnetic diffusivity, which is found to be only weakly dependent on the ReM.
Potters Wheel: An interactive framework for data cleaning

Cleaning organizational data of discrepancies in structure and content is important for data warehousing and Enterprise Data Integration (EDI). Current commercial solutions for data cleaning involve many iterations of time-consuming "data quality" analysis to find errors, and long-running transformations to fix them. Users need to endure long waits and often write complex transformation programs. We present an interactive framework for data cleaning that tightly integrates transformation and discrepancy detection. Users gradually build transformations by adding or undoing transforms, in a intu-itive, graphical manner through a spreadsheet-like interface; the effect of a transformis shown at once on records visible on screen. In the background, the system incrementally searches for discrepancies on the latest transformed version of data, flagging them as they are found. This allows users to gradually construct a transformation as discrepancies are found, and clean the data without writing complex programs or enduring long delays. Balancing the goals of power, ease of specification, and interactive application, we choose a set of transforms that can be used for transformations within data records as well as for higher-order transformations. We also present initial work on optimizing a sequence of transforms.
The `Intergenerational Stake Hypothesis' in Indonesia and Germany

The aim of this study is to test the general hypothesis that parents and their children systematically differ with respect to the perception of their relationship as described by the literature on the `intergenerational stake'. To this end, the study compared 100 dyads of adult daughters and elderly mothers from Indonesia and Germany. Mothers and daughters were interviewed with respect to their value orientations and their evaluation of the present mother—daughter relationship. The results demonstrated that the `intergenerational stake' hypothesis could be replicated for different aspects of the relationship quality in the German sample as compared to the Indonesian sample. Besides a pattern of mother— daughter differences consistent with the `intergenerational stake hypothesis', two groups with different patterns were found: one group in which daughters perceived the relationship as more positive than mothers and another group characterized by low maternal self-disclosure. Culture and mothers' collectivism were associated with the assignment to the latter group. The results are interpreted in a culture-informed theoretical framework of intergenerational relations.
Zinc Intake and Its Dietary Sources: Results of the 2007 Australian National Children’s Nutrition and Physical Activity Survey

The current Australian Nutrient Reference Values (NRV) use different Estimated Average Requirements (EAR) for zinc for adolescent boys and girls compared to the previous recommendations. The adequacy of zinc intakes of 2–16 years old children (n = 4834) was examined in the 2007 Australian National Children’s Nutrition and Physical Activity Survey. Zinc intakes were estimated from two 24-h recalls and compared with age- and gender-specific NRV. Food sources of zinc were assessed and compared with those of the 1995 National Nutrition Survey. The mean (SD) zinc intake was 10.2 (3.0) mg/day for all children. Nearly all children met the EAR for zinc except for 14–16 years old boys (29% did not meet EAR). Children (2–3 years) were at highest risk of excessive zinc intakes with 79% exceeding the Upper Level of Intake. Meat and poultry; milk products; and cereals and cereal products contributed 68% of total zinc intake. The contribution of cereals to total zinc intake has increased significantly since 1995, due to the greater market-availability of zinc-fortified breakfast cereals. We conclude that sub-groups of Australian children are at-risk of inadequate (boys 14–16 years) or excessive (children 2–3 years) zinc intakes, and monitoring of zinc status is required.
Hospital vs Home-Based Exercise Rehabilitation for Patients with Peripheral Arterial Occlusive Disease

Supervised, hospital-based exercise rehabilitation programs are effective for improving functional status for patients with claudication due to peripheral arterial occlusive disease. However, it has been suggested that unsupervised, home-based exercise programs, which have been relatively little evaluated, would be equally efficacious as compared with hospital-based programs. The authors tested the hypothesis that a hospital-based exercise rehabilitation program would improve treadmill exercise perfor mance more than a home-based program. Of 20 consecutively enrolled patients with claudication, 10 were randomly placed into a supervised, hospital-based program and 10 into an unsupervised, home-based program for a three-month period. Exercise perfor mance was evaluated by treadmill testing using a graded protocol. In addition, func tional status was evaluated by the Walking Impairment Questionnaire (WIQ) and the Medical Outcomes Study SF-20 questionnaire (MOS). Patients in the hospital-based program were treated with treadmill walking three times a week for one hour/visit. Patients in the home-based program were instructed to walk at least three times a week and were contacted weekly to provide encouragement and to record compliance with (continued on next page) the program. Patients in the hospital-based group improved peak walking time by 137%, pain-free walking time by 150%, and peak oxygen consumption by 19% (all P<0.05). Patients reported an improved walking distance and speed according to WIQ data (both P<0.05). In addition, the MOS physical functioning score in the hospital-based group improved by 20 percentage points (P<0.05). In contrast, patients in the home-based program did not improve exercise performance measured on the treadmill. Improvement in the ability to walk on the treadmill was greater in the hospital-based than the home- based program (P<0.05). The ability to walk distances was the only questionnaire measure that improved in persons who received the home-based program (P<0.05). Preliminary results suggest that a supervised, hospital-based program is more effective for improving treadmill exercise performance than an unsupervised, home-based program.
The impact of quality of work life on job embeddedness and affective commitment and their co-effect on turnover intention of nurses.

AIMS AND OBJECTIVES To verify with empirical evidence the hypothesised relation and the effect of quality of work life, job embeddedness and affective commitment on turnover intention of clinical nurses in China. BACKGROUND High turnover of the nursing workforce in healthcare organisations is a difficult and recurring problem in China as well as in many other countries in the world. It leads to great waste of resources and increases management cost. Developing and retaining the nursing workforce, which is a major challenge faced by human resources practitioners in hospitals and public health agencies, also becomes a subject of interest for management studies. Most of the literature about voluntary turnover focused on such traditional measures as job satisfaction and job alternatives in the past. The introduction of such new concepts as quality of work life, job embeddedness and affective commitment, which views the issue from a much broader and comprehensive spectrum, made a great breakthrough in the turnover study. In this study, we selected quality of work life, job embeddedness and affective commitment - three of the most important factors in employer-employee relations - and analysed the interaction between each one of them, as well as their co-effect on turnover intention of Chinese nurses. METHODS Cross-sectional survey and structural equation modelling were applied in studying the self-report questionnaires distributed to 1000 nurses employed in five large-scale government-owned hospitals in Heilongjiang Province, Northeast China. FINDINGS Our study confirmed the hypothesised positive relation of quality of work life with job embeddedness and affective commitment and the hypothesised negative relation of quality of work life with turnover intention, that is, high quality of work life perceived by the nurses enhances their job embeddedness and affective commitment and thus reduces their intention to leave the job. CONCLUSIONS The effect of quality of work life is positive on job embeddedness and affection commitment and negative on turnover intention. RELEVANCE TO CLINICAL PRACTICE Nurse managers should pay great attention to the nurses' perception of quality of work life, and make great efforts in developing strategies and projects that can strengthen the nurses' embeddedness or connection with the job.
Multiresolution Recurrent Neural Networks: An Application to Dialogue Response Generation

We introduce a new class of models called multiresolution recurrent neural networks, which explicitly model natural language generation at multiple levels of abstraction. The models extend the sequence-to-sequence framework to generate two parallel stochastic processes: a sequence of high-level coarse tokens, and a sequence of natural language words (e.g. sentences). The coarse sequences follow a latent stochastic process with a factorial representation, which helps the models generalize to new examples. The coarse sequences can also incorporate task-specific knowledge, when available. In our experiments, the coarse sequences are extracted using automatic procedures, which are designed to capture compositional structure and semantics. These procedures enable training the multiresolution recurrent neural networks by maximizing the exact joint log-likelihood over both sequences. We apply the models to dialogue response generation in the technical support domain and compare them with several competing models. The multiresolution recurrent neural networks outperform competing models by a substantial margin, achieving state-of-the-art results according to both a human evaluation study and automatic evaluation metrics. Furthermore, experiments show the proposed models generate more fluent, relevant and goal-oriented responses.
Prospective Evaluation of Surgical Treatment of Humeral Avulsions of the Glenohumeral Ligament

Background: Humeral avulsion of the glenohumeral ligament (HAGL) is an infrequent but significant contributor to shoulder dysfunction, instability, and functional loss. Purpose: To prospectively identify patients with HAGL lesions and then conduct retrospective evaluation of the clinical history, examination findings, and surgical outcomes of these patients. Study Design: Case series; Level of evidence, 4. Methods: Over a 6-year period (2006-2011), patients with shoulder dysfunction and a HAGL lesion that was confirmed via magnetic resonance arthrogram (MRA) were prospectively evaluated with a minimum 2-year follow-up. Patient demographics, presentation, examination, and surgical findings were documented. Outcomes of return to activity as well as Western Ontario Shoulder Instability Index (WOSI) and Single Assessment Numeric Evaluation (SANE) scores were recorded at final follow-up. Anterior HAGL (aHAGL) lesions were repaired with a partial subscapularis tenotomy approach, while reverse (rHAGL) lesions were repaired arthroscopically. Results: Of 28 patients, 27 (96%) completed the study requirements at a mean of 36.2 months (range, 24-68 months). The sample contained 12 females (44%) and 15 males (56%), who had a mean age of 24.9 years (range, 18-34 years). The chief complaint reported was pain in 23 patients (85%), while only 4 (15%) patients complained primarily of recurrent instability symptoms. Fourteen patients (52%) had aHAGL lesions, 10 patients (37%) had rHAGL lesions, and 3 patients (11%) had combined aHAGL and rHAGL lesions. Ten patients (37%) had concomitant HAGL lesions and labral tears, whereas 17 patients (63%) had isolated HAGL lesion without labral tear. The 17 patients (63%) with aHAGL lesions or combined lesions underwent a partial subscapularis tenotomy approach, while the remaining 10 patients (37%) with rHAGL lesions underwent arthroscopic surgical repair. After surgery, WOSI outcomes improved from 54% to 88% and SANE outcomes improved from 50% to 91% (P < .01 for both), with no reports in recurrence of instability symptoms at final follow-up. Conclusion: This study demonstrated that patients with symptomatic HAGL lesions predominantly report shoulder pain and dysfunction, with few chief complaints of recurrent instability complaints. After surgery, patients showed predictable return to full activity, improvement in objective and patient-reported outcomes, and satisfaction with treatment outcome.
Characterization of Yeast Translation Initiation Factor 1A and Cloning of Its Essential Gene (*)

Translation initiation factor eIF1A is required in vitro for maximal rates of protein synthesis in mammalian systems. It functions primarily by dissociating ribosomes and stabilizing 40 S preinitiation complexes. To better elucidate its precise role in promoting the translation initiation process, the yeast form of eIF1A has been identified in Saccharomyces cerevisiae and purified to homogenity on the basis of its cross-reaction with antibodies prepared against mammalian eIF1A. The apparent mass of yeast eIF1A (22 kDa) resembles that of the mammalian homolog (20 kDa), and the yeast factor is active in stimulating methionyl-puromycin synthesis in an assay composed of mammalian components. The gene encoding yeast eIF1A, named TIF11, was cloned and shown to be single copy. TIF11 encodes a protein comprising 153 amino acids (17.4 kDa); the deduced amino acid sequence exhibits 65% identity with the sequence of human eIF1A. Both human and yeast eIF1A contain clusters of positive residues at the N terminus and negative residues at the C terminus. Deletion/disruption of TIF11 demonstrates that eIF1A is essential for cell growth. Expression of human eIF1A cDNA rescues the growth defect of TIF11-disrupted cells, indicating that the structure/function of yeast and mammalian eIF1A is highly conserved.
Exploring Different Representational Units in English-to-Turkish Statistical Machine Translation

We investigate different representational granularities for sub-lexical representation in statistical machine translation work from English to Turkish. We find that (i) representing both Turkish and English at the morpheme-level but with some selective morpheme-grouping on the Turkish side of the training data, (ii) augmenting the training data with "sentences" comprising only the content words of the original training data to bias root word alignment, (iii) reranking the n-best morpheme-sequence outputs of the decoder with a word-based language model, and (iv) using model iteration all provide a non-trivial improvement over a fully word-based baseline. Despite our very limited training data, we improve from 20.22 BLEU points for our simplest model to 25.08 BLEU points for an improvement of 4.86 points or 24% relative.
