Joint user pairing and resource allocation for virtual MIMO in uplink SC-FDMA system

In this paper, we study the joint user pairing and resource allocation problem for uplink single carrier frequency-division multiple access (SC-FDMA) system with virtual multiple-input multiple-output (V-MIMO) implemented. Different from existing relevant researches, we consider a universal solution based on profit function for this problem instead of studying a particular scheduling policy, and then we explain that it is a MAX SNP-hard problem with high complexity. After that, we will propose a low-complexity heuristic algorithm called First User First (FuF), which is based on the idea of allocating resource to one user first. Moreover, in order to get a more accurate theoretical approximation to this problem, we will propose a constant factor approximation algorithm with polynomial-time complexity using local ratio technique. The simulation results of our algorithms show that the B-LRT algorithm has robust performance compared with other popular algorithms, while the FuF algorithm has lowest computation complexity at the expense of a little performance loss.
Relationship of Cognition to Clinical Response in First-Episode Schizophrenia Spectrum Disorders.

First-episode schizophrenia (FES) spectrum disorders are associated with pronounced cognitive dysfunction across all domains. However, less is known about the course of cognitive functioning, following the first presentation of psychosis, and the relationship of cognition to clinical course during initial treatment. The present longitudinal study examined the magnitude of neurocognitive impairment, using the MATRICS Consensus Cognitive Battery, in patients experiencing their first episode of psychosis at baseline and after 12 weeks of randomized antipsychotic treatment with either aripiprazole or risperidone. At baseline, FES patients evidenced marked impairments in cognitive functioning. Notably, performance on the mazes task of planning and reasoning significantly predicted the likelihood of meeting stringent criteria for positive symptom remission during the first 12 weeks of the trial. Performance on indices of general cognitive function, working memory, and verbal learning improved over time, but these improvements were mediated by improvements in both positive and negative symptoms. We did not detect any differential effects of antipsychotic medication assignment (aripiprazole vs risperidone) on cognitive functioning. Our results suggest that a brief paper-and-pencil measure reflecting planning/reasoning abilities may index responsivity to antipsychotic medication. However, improvements in cognitive functioning over time were related to clinical symptom improvement, reflecting "pseudospecificity. "
The Catalytic Efficiency of Lipin 1β Increases by Physically Interacting with the Proto-oncoprotein c-Fos*

Background: Lipin 1β is a phosphatidic acid (PA) phosphatase that generates diacylglycerol for lipid synthesis. Results: Lipin 1β enzymatic activity is increased by c-Fos. For this, both proteins engage in a physical interaction. The c-Fos domains involved in binding to and activating lipin are not the same. Conclusion: c-Fos is a novel positive regulator of lipin1β activity. Significance:c-Fos could regulate glycerolipid synthesis by controlling PA fate. Phosphatidic acid (PA) is a central precursor for membrane phospholipid biosynthesis. The lipin family is a magnesium-dependent type I PA phosphatase involved in de novo synthesis of neutral lipids and phospholipids. The regulation of lipin activity may govern the pathways by which these lipids are synthesized and control the cellular levels of important signaling lipids. Moreover, the proto-oncoprotein c-Fos has an emerging role in glycerolipid synthesis regulation; by interacting with key synthesizing enzymes it is able to increase overall phospho- and glycolipid synthesis. We studied the lipin 1β enzyme activity in a cell-free system using PA/Triton X-100 mixed micelles as substrate, analyzing it in the presence/absence of c-Fos. We found that lipin 1β kcat value increases around 40% in the presence of c-Fos, with no change in the lipin 1β affinity for the PA/Triton X-100 mixed micelles. We also probed a physical interaction between both proteins. Although the c-Fos domain involved in lipin activation is its basic domain, the interaction domain is mapped to the N-terminal c-Fos. In conclusion, we provide evidence for a novel positive regulator of lipin 1β PA phosphatase activity that is not achieved via altering its subcellular localization or affinity for membranes but rather through directly increasing its catalytic efficiency.
A spatial study of reported domestic violence in Brisbane: A social justice perspective

Domestic violence is increasingly being recognized as a major social problem in Australian society. An alarming number of homicides and serious physical injuries, especially to women, have been directly attributed to domestic violence. The main aim of this study was to examine the reported incidence of domestic violence for the city of Brisbane in Australia and compare these findings to those of previous research. Previous research both in Australia and overseas based on quantitative analysis of reported incidences of domestic violence show higher incidence rates of domestic violence among the most disadvantaged groups in society. Data for this research came from two main sources. Calls made to police with regard to domestic violence incidents were one main source of data, while applications to courts for domestic violence protection orders provided the second major data source. Calls made to a domestic violence telephone service were also used in this research. A quantitative methodology was used in this study to ensure comparability of findings with previous research. This methodology also permitted a spatial analysis of the pattern of the incidence rate of reported domestic violence by Statistical Local Area or suburb for Brisbane. Such spatial analysis of the incidence rate of reported domestic violence is largely absent from previous domestic violence research. Data was also obtained for a number of measures of disadvantage. These measures included low income, unemployment, race, non-English speaking background, locational disadvantage and a measure of multiple disadvantages referred to as the SEIFA Index of Relative SocioEconomic Disadvantage. Correlation, regression and analysis of variance were the statistical methods used in this study.
Wideband stacked patch antenna array on LTCC for W-band

A design of a stacked microstrip patch antenna and a 16-element array on Ferro A6-M LTCC operating at W-band is presented. A parasitic patch is added on LTCC substrate to increase bandwidth. The stacked configuration is designed by using an equivalent circuit together with EM simulators. The manufactured antenna array is integrated with a WR-10-to-microstrip-line transition to facilitate RF testing. The S-parameters are measured on a probe station and radiation pattern testing is done using a WR-10 excitation in anechoic chamber. The array of size 9.3 mm × 9.3 mm × 0.4 mm has the measured maximum gain of 14.2 dBi at 84 GHz and gain higher than 11.2 dBi between 78.5 GHz and 98.5 GHz which results as −3-dB radiation bandwidth of 23%. The antenna efficiency of the array is 48% at the highest.
The hypothalamic-pituitary-adrenal axis and immune-mediated inflammation.

Celsus described four of the five cardinal signs of inflammation 2000 years ago, and Eustachio discovered the adrenal glands almost 500 years ago, but not until 1936 did Selye note that in rats exposed to stressors, the adrenal glands were enlarged, and the thymus and lymph nodes shrunken.1–3 Cortisone, the active principle of the adrenal glands, was isolated by Kendall and Reichstein in the late 1940s and shown to suppress immune organs. These scientists, along with Hench, received the Nobel Prize in Physiology and Medicine, after Hench and colleagues showed that cortisone could ameliorate rheumatoid arthritis.4,5 In recent .
Evaluating authentic behaviour change in leadership development programmes

The global economic crisis that hit the western countries strongly has emphasised the need to abandon the economic-performance significance of leadership and return to a meaning-making significance. While a lot of research has been done in the field of leadership and management disciplines, little has been done on how to develop leadership. This study evaluated the degree in which leadership training in the market-place today was effective at developing authentic leadership and, therefore, at changing individual behaviour. Since none of the leadership theories address how behavioural change is actually achieved, theories of change were integrated in the current study. A conceptual model combining Authentic Leadership Development (ALD) theory and the Theory of Planned Behaviour (TPB) was proposed. Furthermore, this study explored the relationship between a positive contemplation of change and the actual change observed in individuals after the leadership intervention. In order to test this conceptualisation, a longitudinal quasi-experimental study was conducted. Leaders were surveyed in this study one month before and one month after the programme. Three complementary questionnaires were distributed to participants in one of four leadership development programmes (two corporate initiatives and two business-school programmes). Analyses showed that leaders who attended a leadership intervention (as compared to a control group) developed higher levels of authentic leadership, as rated by them-selves and others in their working environment and controlling for baseline scores. The results also indicated that intentions were developed through the interventions and that the development of such intentions translated into changes in authentic behaviour. Intentions mediated the relationship between attitude and authentic leader-ship. In addition, when contemplation of change was high and attitudes towards authentic leadership were positive, the development of intentions was stronger. The implications of these findings for the theory and practice of leadership development programmes and the impact on organisational performance are discussed.
Enhancing Zoom and Pan in Ultrasound Machines with a Multimodal Gaze-based Interface

We present the first iteration of a user-centred design for integrating an eye gaze tracker with ultrasound (US) machine interfaces used in routine diagnostic sonography. The aim is to speed up the interaction of the sonographer with the machine, offer a more ergonomic solution while minimizing the cognitive load and maintaining the produced image quality. In this iteration, we target pan and zoom functions. Field studies and observations have led to two design alternatives. A feasibility study of two design approaches determined from field studies is done using a functional prototype. Results from six sonographers provided evidence for the potential of a multimodal gaze-based interface for US machines. Results from the feasibility study have also led to a second design iteration that combines the advantages of both gaze-based designs.
Effects of a moving X-line in a time-dependent reconnection model

Abstract. In the frame of magnetized plasmas, reconnection appears as an essential process for the description of plasma acceleration and changing magnetic field topology. Under the variety of reconnection regions in our solar system, we focus our research onto the Earth's magnetotail. Under certain conditions a Near Earth Neutral Line (NENL) is free to evolve in the current sheet of the magnetotail. Reconnection in this region leads to the formation of Earth- and tailward propagating plasma bulges, which can be detected by the Cluster or Geotail spacecraft. Observations give rise to the assumption that the evolved reconnection line does not provide a steady state behavior, but is propagating towards the tail (e.g., Baker et al., 2002). Based on a time-dependent variant of the Petschek model of magnetic reconnection, we present a method that includes an X-line motion and discuss the effects of such a motion. We focus our main interest on the shock structure and the magnetic field behavior, both for the switch-on and the switch-off phase.
POLYAMINES IN PLANTS

The available information on plant polyamines is reviewed. The polycationic character of polyamines is suggested as a rationale of their properties and functions. Different aspects of polyamines are examined: chemistry, occurrence, localization, uptake, transport, interactions with nucleic acids, proteins, membranes and cell walls, and role in maintaining of pH, ion and osmotic cell homeostasis. The biosynthetic and catabolic pathways of polyamines and their relation to the overall metabolism, especially to the alcaloid formation, are outlined. The physiological functions of polyamines are discussed, namely their involvement in cell cycle, cell division, growth, development, senescence, as well as in stress phenomena. Alternative views on polyamines as a new class of plant growth regulators or second messengers are presented. An emphasis is laid on the phenylamides (conjugates of polyamines and hydroxy cinnamic acids) as specific plant molecules with regulatory and radical scavenging properties. The possibilities for practical application of polyamines are concerned.
The Interracial Sublime: Gender and Race in Charlotte Dacre’s Zofloya

This essay argues that Charlotte Dacre’s Zofloya (1806) presents an interracial sublime in the form of the dissolution of the European home/family. Dacre, I suggest, traces this dissolution to the European woman’s assertion of agency by stepping outside spatial, familial, racial and sexual boundaries. In the first section it examines the crisis of European domesticity where the family and the parent/s fail in their responsibilities toward the children. In section two I suggest that within the dissolving home/family we see the European woman, Victoria, subverting further the dissolution. The arrival of the Moor within the house compounds the blurring of hierarchies and ordering. In the final section I trace the features of the interracial sublime. I conclude by proposing that Dacre’s interracial sublime serves the purpose of demonstrating the permeability of European borders - a permeability that wreaks disaster. Dacre’s tale therefore ultimately functions as a caution against the woman’s emancipated and agential actions.
Predicting Serious Violent and Serious Property Offending: School- and Family-Problem Risk Factors Revealed by Incarcerated Youth

Serious violent young offenders have been described as “a rare species. ” Most general population studies do not examine serious and violent young offenders. The vast majority of research on school risk factors and offending focus on delinquency as opposed to serious and violent offending by youth. Research has demonstrated that school problems (poor academic performance, truancy, dropout) are related to delinquency. The aim of the current study is to assess whether school and family problems are significant predictors of serious violent and serious property offences for incarcerated youth. This study also examines whether Aboriginal ethnicity is a significant predictor of serious violent and serious property offences. Data for this thesis is from a sample of serious and violent young offenders in custody drawn from two secure custody facilities and two open custody units located in a major urban centre of British Columbia, Canada (n = 404). The sample consists of youth (aged 12–19) who were interviewed as part of the research project entitled the Vancouver Serious and Violent Incarcerated Young Offenders Study. Bivariate tests and logistic regression models are used to analyze the role of school and family problems in predicting serious violent and serious property offences. Results show that school problems, family problems, age, mental health problems, and substance use are significant predictors of serious violent offences. Family problems, mental health problems, gender, and Aboriginal ethnicity are significant predictors of serious property offences. School problems, gender, age, mental health problems, and
The role of mesoscopic structuring on the intermixing of spin-polarised conduction channels in thin-film ferromagnets for spintronics

The separation of spin-up and spin-down conduction channels is fundamental to electronic transport in ferromagnets and essential for spintronic functionality. The spin states available for conduction are defined by the ferromagnetic material, but additional physical factors can affect scattering and modify the spin-dependence of conduction. Here the effect of mesoscopic structuring, arising during the growth of ferromagnetic thin films, on the electronic transport was investigated. Resistivity and anisotropic magnetoresistance were measured in a series of Ni80Fe20 thin films as a function of nominal film thickness from 3 nm up to 20 nm . The observed thickness dependence of the resisivity and magnetic anisotropy of resistivity are interpreted using a model that accounts for the macroscopic structuring from the growth of the films and incorporates a structural dependence of the spin-flip scattering. The model shows good agreement for both the thickness dependence of the resistivity and the reduction of the anisotropic magnetoresistivity. The latter indicating that increasing mixing of the conducting spin channels occurs in ultra-thin films, mainly a consequence of macroscopic structuring of the films.
Stock Options and Managerial Incentives to Invest

We examine the effect of stock options on managerial incentives to invest. Our chief innovation is a model wherein firm value and executive decisions are endogenous. Numerical solutions to our model show that managerial incentives to invest are multi-dimensional and highly sensitive to option strike prices, the manager's wealth, degree of diversification, risk aversion, and career concerns. We show that under- and over-investment problems can be large and economically significant, with hurdle rates ranging from more than 20 percentage points below to more than 35 percentage points above shareholders' required rate of return. Finally, firm value is not a strictly increasing function of a manager's incentive compensation or conventional pay–performance sensitivity metrics. Stronger managerial incentives to invest can benefit or harm a firm.
Characterization of a monoclonal antibody that induces the acrosome reaction of sea urchin sperm

A monoclonal antibody, J18/29, induces the acrosome reaction (AR) in spermatozoa of the sea urchin Strongylocentrotus purpuratus. J18/29 induces increases in both intracellular Ca2+ and intracellular pH similar to those occurring upon induction of the AR by the natural inducer, the fucose sulfate-rich glycoconjugate of egg jelly. Lowering the Ca2+ concentration or the pH of the seawater inhibits the J18/29- induced AR, as does treatment with Co2+, an inhibitor of Ca2+ channels. The J18/29-induced AR is also inhibited by verapamil, tetraethylammonium chloride, and elevated K+. All these treatments cause similar inhibition of the egg jelly-induced AR. J18/29 reacts with a group of membrane proteins ranging in molecular mass from 340 to 25 kD, as shown by immunoprecipitation of lysates of 125I-labeled sperm and Western blots. The most prominent reacting proteins are of molecular masses of 320, 240, 170, and 58 kD. The basis of the multiple reactivity appears to reside in the polypeptide chains of these proteins, as J18/29 binding is sensitive to protease digestion but resistant to periodate oxidation. There are approximately 570,000 sites per cell for J18/29 binding. J18/29 is the only reagent of known binding specificity that induces the AR; it identifies a subset of sperm membrane proteins whose individual characterization may lead to the isolation of the receptors involved in the triggering of the AR at fertilization.
Deconstructed Higgsless models with one-site delocalization

In this note we calculate the form of electroweak corrections in deconstructed Higgsless models for the case of a fermion whose weak properties arise from two adjacent $SU(2)$ groups on the deconstructed lattice. We show that, as recently proposed in the continuum, it is possible for the value of the electroweak parameter $\ensuremath{\alpha}S$ to be small in such a model. In addition, by working in the deconstructed limit, we may directly evaluate the size of off-$Z$-pole electroweak corrections arising from the exchange of Kaluza-Klein modes; this has not been studied in the continuum. The size of these corrections is summarized by the electroweak parameter $\ensuremath{\alpha}\ensuremath{\delta}$. In one-site delocalized Higgsless models with small values of $\ensuremath{\alpha}S$, we show that the amount of delocalization is bounded from above, and must be less than 25% at 95% C.L. We discuss the relation of these calculations to our previous calculations in deconstructed Higgsless models, and to models of extended technicolor. We present numerical results for a four-site model, illustrating our analytic calculations.
Order parameter fluctuations at a buried quantum critical point

Quantum criticality is a central concept in condensed matter physics, but the direct observation of quantum critical fluctuations has remained elusive. Here we present an X-ray diffraction study of the charge density wave (CDW) in 2H-NbSe2 at high pressure and low temperature, where we observe a broad regime of order parameter fluctuations that are controlled by proximity to a quantum critical point. X-rays can track the CDW despite the fact that the quantum critical regime is shrouded inside a superconducting phase; and in contrast to transport probes, allow direct measurement of the critical fluctuations of the charge order. Concurrent measurements of the crystal lattice point to a critical transition that is continuous in nature. Our results confirm the long-standing expectations of enhanced quantum fluctuations in low-dimensional systems, and may help to constrain theories of the quantum critical Fermi surface.
Goldilocks

We present GOLDILOCKS, a Java runtime that monitors program executions and throws a DataRaceException when a data race is about to occur. This prevents racy accesses from taking place, and allows race conditions to be handled before they cause errors that may be difficult to diagnose later. The DataRaceException is a valuable debugging tool, and, if supported with reasonable computational overhead, can be an important safety feature for deployed programs. Experiments by us and others on race-aware Java runtimes indicate thatthe DataRaceException may be a viable mechanism to enforce the safety of executions of multithreaded Java programs. An important benefit of DataRaceException is that executions in our runtime are guaranteed to be race free and thus sequentially consistent as per the Java Memory Model. This strong guarantee provides an easy-to-use, clean semantics to programmers, and helps to rule out many concurrency-related possibilities as the cause of errors. To support the DataRaceException, our runtime incorporates the novel Goldilocks algorithm for precise dynamic race detection. The Goldilocks algorithm is general, intuitive, and can handle different synchronization patterns uniformly.
