Transmit Beamforming in Rayleigh Product MIMO Channels: Capacity and Performance Analysis

This paper presents an analytical performance investigation of transmit beamforming (BF) systems in Rayleigh product multiple-input multiple-output (MIMO) channels. We first derive new closed-form expressions for the cumulative distribution function, probability density function, and moments of the maximum eigenvalue of a product of independent complex Gaussian matrices, which are used to provide a complete statistical characterization of the received signal-to-noise ratio (SNR). We then derive a number of key performance metrics, including outage probability, symbol error rate, and ergodic capacity. We examine, in detail, three important special cases of the Rayleigh product MIMO channel: the degenerate keyhole scenario and the multiple-input single-output and single-input multiple-output scenarios, for which we derive insightful closed-form expressions for various exact and asymptotic measures (e.g., diversity order, array gain, and high SNR power offset, among others). We also compare the performance of transmit BF with orthogonal space-time block codes and quantify the benefit of exploiting transmitter channel knowledge in Rayleigh product MIMO channels. This is shown to be significant even for low-dimensional systems.
Modulation of NKT cells and Th1/Th2 imbalance after α-GalCer treatment in progressive load-trained rats

Purpose: The purpose of this study was to determine whether α-galactosylceramide (α-GalCer), a synthetic glycolipid agonist of natural killer T (NKT) cells, can ameliorate exercise-induced immune imbalance. Methods: Eight-week-old female Sprague-Dawley rats were trained with a progressively increasing load for 9 weeks. At 36 h and at 7 d after training, groups of rats were euthanized. The whole blood was used to detect hemoglobin(Hb), plasma was analyzed for hormones testosterone(T) and corticosterone(C), and spleen was harvested for detecting NKT cells and interferon-γ (IFN-γ) and interleukin (IL)-4 producing cells. Results: Two-way analysis of variance (ANOVA) showed significant differences between training and time in Series 1. The results showed, at 36h after training, that the decrease in Hb, T and C concentration reflected overtraining or excessive exercise. At 7 d after training, NKT cell populations decreased, and a T helper 1/T helper 2 (Th1/Th2) lymphocyte imbalance occurred. In Series 2, α-galactosylceramide (α-GalCer), an NKT cell activator was found to enhance NKT cell numbers by 69% and shift the Th1/Th2 lymphocyte imbalance by observably decreasing the frequency of IL-4 secreting cells. Conclusion: These data showed that, in addition to Th1/Th2 self-regulation, α-GalCer played an important modulatory role in the exercise-induced Th1/Th2 lymphocyte imbalance, which may be correlative with NKT immunoregulatory cells.
Plasma Adiponectin Concentration and Its Association with Metabolic Syndrome in Patients with Heart Failure

Purpose Plasma adiponectin concentrations are inversely related with metabolic syndrome (MetS), and MetS is associated with increased risk for heart failure (HF). However, the relationship between adiponectin and MetS in HF remains undetermined. Therefore, we tested whether MetS was associated with the degree of plasma adiponectin concentrations in HF patients. Materials and Methods One hundred twenty eight ambulatory HF patients with left ventricular ejection fraction of <50% (80 males, 61.8±11.9 years old) were enrolled for this cross-sectional study. Echocardiographic measurements were performed, and plasma concentrations of adiponectin, lipoproteins, apolipoproteins (apoB, apoA1) and high sensitive C-reactive protein (hsCRP) were measured. Results Adiponectin concentrations in HF patients with MetS (n=43) were significantly lower than those without MetS (n=85) (9.7±7.0 vs. 15.8±10.9 µg/mL, p=0.001). Higher concentrations of apoB (p=0.017), apoB/A1 ratio (p<0.001), blood urea nitrogen (p=0.034), creatinine (p=0.003), and fasting insulin (p=0.004) were observed in HF patients with MetS compared with those without MetS. In HF patients with MetS, adiponectin concentrations were negatively correlated with hsCRP (r=-0.388, p=0.015) and positively correlated with the ratio of early mitral inflow velocity to early diastolic mitral annular velocity, E/E' (r=0.399, p=0.015). There was a significant trend towards decreased adiponectin concentrations with an increasing number of components of MetS (p for trend=0.012). Conclusion Our study demonstrated that adiponectin concentrations decreased in HF patients with MetS, and that relationship between adiponectin, inflammation and abnormal diastolic function, possibly leading to the progression of HF.
An Experiment of Reengineering Technology to Support Military Communication in a Strategic Environment

This research tested a reengineering approach to achieving Secure RBAC in a dynamic communication environment. In order to defend the United States against enemies foreign and domestic; it is crucial that scientist and combat operators collaborate to create innovative processes from existing technology and implement the best communication equipment available. 21 years technology experience in a military environment supports this research and contributes a collaboration of different systems that could revolutionize the existing government communication process. The Mobile Secure Role Base Access Control Network is a system composed of several other technologies designed to access secure global databases via wireless and wired communication platforms [2]. This research involved the development of a Database network, for wireless vs. wired access connectivity. Forty database access scenarios were tested during day and night hours, for performance analysis. After compiling the results of the experimental process, it was evident that the Iridium Satellite gateway was ineffective as a communication service to access the database in a global strategic environment.
Change in Depression Symptoms Through Emerging Adulthood

Existing research suggests there may be important association between mental health and the employment that emerging adults obtain during the transition into the workforce. Hierarchical linear modeling (HLM) was used to examine the trajectories of emerging adults’ depression symptoms over a 4-year period, as a function of two characteristics of employment: type of work (i.e., full-time or not) and job satisfaction (i.e., highly satisfied with work or not). The sample consisted of 793 young Canadians drawn from the National Longitudinal Survey of Children and Youth. On average, depression symptoms decreased significantly over time. Full-time employment was associated with lower initial levels of depression and a slower decrease in symptoms. Higher job satisfaction also associated with lower initial levels of depression symptoms. These results suggest it is important to consider both these characteristics of employment to more fully understand how employment is connected to depression symptoms over time.
Paired Peer Review in a Distance-taught EFL Writing Course

Researchers have adopted diverse perspectives on the effect of peer review on student writing in the field of teaching English as a First Language (E1L) and English as a Second/Foreign Language (ESL/EFL) in the past two decades. Nevertheless, researches have chiefly centered on conventional learning settings with on-campus students in mind; scant attention has been paid to peer review in the distance learning context despite the fact that distance EFL learning is a growing branch of English Language Teaching (ELT) in the world today. To fill the gap, this study reports on an action research project into paired peer review in a distance-taught EFL writing course at an open university in China to investigate the extent to which peer feedback was used to improve EFL writing, how it was accepted by Chinese distance English learners and how it impacted on their transferrable skills and self-efficacy, i.e. ‘beliefs in one’s capabilities to organize and execute the courses of action required to produce given attainments’(Bandura, 1997, p. 3). Findings from the study indicate that peer review has yielded good educational benefits in these areas although there is still room for improvement. The article also discusses ways to overcome obstacles and to tap into the potential benefits of peer review in the study of other courses.
Lipid-Based Nanovectors for Targeting of CD44-Overexpressing Tumor Cells

Hyaluronic acid (HA) is a naturally occurring glycosaminoglycan that exists in living systems, and it is a major component of the extracellular matrix. The hyaluronic acid receptor CD44 is found at low levels on the surface of epithelial, haematopoietic, and neuronal cells and is overexpressed in many cancer cells particularly in tumour initiating cells. HA has been therefore used as ligand attached to HA-lipid-based nanovectors for the active targeting of small or large active molecules for the treatment of cancer. This paper describes the different approaches employed for the preparation, characterization, and evaluation of these potent delivery systems.

Gender Inequality and Knowledge Production in Criminology and Criminal Justice

Studies show that co-authorship of scholarly articles in criminology and criminal justice journals are stratified by gender: males are more likely to publish with males, females are more likely to publish with males. Increasing co-authorship has led some to claim that the intellectual contributions of females may be devalued, systematically putting them at a disadvantage for tenure and promotion decisions. Despite the importance of understanding gender inequality in knowledge production, no studies have examined the mechanisms that produce this outcome. Using data from 656 publications in five journals, we examine the structure of gender and co-authorship by testing two mechanisms that may generate a gendered distribution among scholarly articles. Although females exhibit a greater proclivity toward co-authorship with males, we show that this is a consequence of higher productivity among males. The tendency for males to have higher productivity than females in publications actually increases the likelihood of cross-gender collaboration.
Racialised dissatisfaction: homelessness management and the everyday assemblage of difference

Faced with increased waves of refugees, economic migrants and internal vulnerable groups, the challenge for the contemporary European city is to welcome, assist and manage these populations in ways capable of fostering a positive and productive articulation of difference. The paper tackles this issue by investigating the ways in which difference is perceived, negotiated and performed among Italian and migrant homeless people in Turin, Italy. Through the presentation of detailed ethnographic material, the paper proposes a processual and affective take on the everyday assemblage of race and it questions the role of normative spaces in its making. The notion of racialised dissatisfaction is advanced in this sense, signalling how street-level racism among the homeless poor is deeply connected to the broader machinery of homelessness management and the material and affective components of life on the street. Despite its contextualised ethnographic nature, the paper offers insights that encompass the analysed case and advance our theoretical and empirical understanding of everyday life at the urban margins.

A compositional approach to multiparadigm programming

The author points out that although different aspects of a system require different approaches, programmers are confined to their language's one paradigm. Multiparadigm programming makes it possible to match the paradigm to the problem. The potential of paradigm composition as an approach to multiparadigm programming is explored. In paradigm composition, a multiparadigm program is written as a collection of single-paradigm programs. The single-paradigm programs are composed, which means that they execute concurrently and cooperatively to form the whole of a functioning system. Interactions between paradigms are defined at the conceptual levels of the participating paradigms. The case of a small prototype telephone network is considered as an example of paradigm composition. <<ETX>>
GENDER DIFFERENCES IN RESPONSE TO BIG STAKES

It is commonly perceived that increasing incentives improves performance. However, the reaction to increased incentives might differ between men and women, leading to gender differences in performance. In a natural experiment, we study the gender difference in performance resulting from changes in stakes. We use detailed information on the performance of high-school students and exploit the variation in the stakes of tests, which range from 5% to 27% of the final grade. We find that female students outperform male students in all tests—but to a relatively larger degree when the stakes are low. The gender gap disappears in tests taken at the end of high school, which count for 50% of the university entry grade.
Sparse Approximation and Recovery by Greedy Algorithms

We study sparse approximation by greedy algorithms. Our contribution is twofold. First, we prove exact recovery with high probability of random K-sparse signals within ΓK(1+ε)l iterations of the orthogonal matching pursuit (OMP). This result shows that in a probabilistic sense, the OMP is almost optimal for exact recovery. Second, we prove the Lebesgue-type inequalities for the weak Chebyshev greedy algorithm, a generalization of the weak orthogonal matching pursuit to the case of a Banach space. The main novelty of these results is a Banach space setting instead of a Hilbert space setting. However, even in the case of a Hilbert space, our results add some new elements to known results on the Lebesgue-type inequalities for the restricted isometry property dictionaries. Our technique is a development of the recent technique created by Zhang.
Federal Reserve Bank of Minneapolis Research Department Staff Report 466 Financial Frictions and Fluctuations in Volatility *

During the recent U.S. financial crisis, the large decline in economic activity and credit was accompanied by a large increase in the dispersion of growth rates across firms. However, even though aggregate labor and output fell sharply during this period, labor productivity did not. These features motivate us to build a model in which increased volatility at the firm level generates a downturn but has little effect on labor productivity. In the model, hiring inputs is risky because financial frictions limit firms' ability to insure against shocks that occur between the time of production and the receipt of revenues. Hence, an increase in idiosyncratic volatility induces firms to reduce their inputs to reduce such risk. We find that our model can generate about 67% of the decline in output of the Great Recession of 2007—2009. * The views expressed herein are those of the authors and not necessarily those of the Federal Reserve Bank of Minneapolis or the Federal Reserve System.
Understanding urgency in borderline personality disorder: disinhibition or impulsive emotion regulation?

Borderline Personality Disorder (BPD) is a serious and costly disorder characterized by emotional dysregulation and risky, impulsive behaviors. Urgency is a type of impulsivity that has been strongly associated with symptoms of BPD, and it remains unclear whether Urgency represents a failure of self-regulation under conditions of strong emotions or whether Urgency reflects short-term attempts to regulate strong emotions. A useful method for studying the role of strong emotions in impulsive behaviors is “mood freezing”. Mood freezing is a technique that uses a placebo to create a context in which individuals believe that they are unable to change their mood for a period of time. The present study utilizes a mood freezing manipulation to examine whether Urgency in individuals with and without BPD is associated with emotion regulation index behaviors during a psychologically stressful task (modified PASAT-C; Lejuez, Kahler, & Brown, 2003). Two-way independent analyses of variance (ANOVAs) were utilized to examine both main effects and interaction effects of group and condition on the frequency of emotion regulation index behaviors during the stressful task to determine if these behaviors were functioning as short-term emotion regulation strategies. Analyses showed a significant main effect of condition on number of pauses during the PASAT-C, and a significant group effect on time to first pause during the PASAT-C, with trends towards both groups converging on more pausing at an earlier time point under conditions of a mood freeze manipulation. Urgency was the only significant predictor of both number of pauses and time to first pause in a linear regression analysis including BPD symptoms, experiential avoidance, and delay discounting. Secondary analyses showed slowed reaction time on a modified Stroop task in the high BPD trait group, a significantly larger effect of the mood induction manipulation on the high BPD trait group, and a significant correlation between Urgency and BPD symptoms. Study results support URGENCY AND EMOTION IN BPD v the conclusion that Urgency is the type of impulsivity most highly related to BPD symptoms, and that Urgency is related to emotional regulation and distress tolerance behaviors. Limitations and future directions are discussed. URGENCY AND EMOTION IN BPD vi
Sentiment Analysis in Czech Social Media Using Supervised Machine Learning

This article provides an in-depth research of machine learning methods for sentiment analysis of Czech social media. Whereas in English, Chinese, or Spanish this field has a long history and evaluation datasets for various domains are widely available, in case of Czech language there has not yet been any systematical research conducted. We tackle this issue and establish a common ground for further research by providing a large humanannotated Czech social media corpus. Furthermore, we evaluate state-of-the-art supervised machine learning methods for sentiment analysis. We explore different pre-processing techniques and employ various features and classifiers. Moreover, in addition to our newly created social media dataset, we also report results on other widely popular domains, such as movie and product reviews. We believe that this article will not only extend the current sentiment analysis research to another family of languages, but will also encourage competition which potentially leads to the production of high-end commercial solutions.
Molecular Mapping and Validation of a Major QTL Conferring Resistance to a Defoliating Isolate of Verticillium Wilt in Cotton (Gossypium hirsutum L.)

Verticillium wilt (VW) caused by Verticillium dahliae Kleb is one of the most destructive diseases of cotton. Development and use of a VW resistant variety is the most practical and effective way to manage this disease. Identification of highly resistant genes/QTL and the underlining genetic architecture is a prerequisite for developing a VW resistant variety. A major QTL qVW-c6-1 conferring resistance to the defoliating isolate V991 was identified on chromosome 6 in LHB22×JM11 F2∶3 population inoculated and grown in a greenhouse. This QTL was further validated in the LHB22×NNG F2∶3 population that was evaluated in an artificial disease nursery of V991 for two years and in its subsequent F4 population grown in a field severely infested by V991. The allele conferring resistance within the QTL qVW-c6-1 region originated from parent LHB22 and could explain 23.1–27.1% of phenotypic variation. Another resistance QTL qVW-c21-1 originated from the susceptible parent JM11 was mapped on chromosome 21, explaining 14.44% of phenotypic variation. The resistance QTL reported herein provides a useful tool for breeding a cotton variety with enhanced resistance to VW.
Role of mangrove habitat as a nursery for juvenile spiny lobster, Panulirus argus, in Belize.

The use of mangrove prop roots and associated coralline habitats by Caribbean spiny lobsters was investigated near two types of mangrove islands in Belize. Spiny lobsters sheltered among mangrove prop roots, in undercut peat banks and under corals near islands, and they ranged in size from newly recruited juveniles to subadults. Lobsters preferred to shelter under large stony corals, but their use of mangrove prop roots nd undercut peat banks increased when the density of corals was low. Den residence time and distance moved within a site were similar at islands isolated by deep water channels and islands separated by shallow seagrass beds, but as a consequence of high immigration rates, population sizes were highest near shallow islands. Predation on newly settled juveniles was greater in seagrass and coral crevices than in mangrove prop roots, whereas the survival of larger juveniles was higher in mangroves and coral patch reefs than in seagrass. These results suggest that mangrove habitats may function as a nursery for juvenile spiny lobsters but that the use of this habitat depends on shelter characteristics and the isolation of islands.
