A Self-Optimization of the Dynamic Resource Management Based on the Cognitive Radio

This paper describes a novel self-optimized approach for resource management based on the cognitive radio in the cellular networks. The cognitive radio techniques offer several features like autonomy, sensing and negotiation. The use of cognitive radio approach gives greater autonomy to the base stations in the cellular networks. This autonomy allows an increase in flexibility to deal with new situations in the traffic load. The negotiation strategy is used to avoid conflicts in the resource allocation. The goal of the cognitive radio scheme is to achieve a high degree of resource usage and a low rate of call blocking in the cellular systems.
Modeling of thermal behavior in the amorphous silicon thin film transistors

This paper proposed a two-dimensional thermal impedance model for amorphous silicon thin film transistors (a-Si:H TFTs) from a system of coupled energy equations, heat flowing equations and boundary conditions. By using of this model, the channel temperature distribution and thus the maximum channel temperature can be calculated. This model can be applied to describe the thermal behavior and thermal reliability of a-Si:H TFTS in the design phase.
On the Two-User Interference Channel With Lack of Knowledge of the Interference Codebook at One Receiver

In multiuser information theory, it is often assumed that every node in the network possesses all codebooks used in the network. This assumption may be impractical in distributed ad hoc, cognitive, or heterogeneous networks. This paper considers the two-user interference channel with one oblivious receiver (IC-OR), i.e., one receiver lacks knowledge of the interfering cookbook, whereas the other receiver knows both codebooks. This paper asks whether, and if so how much, the channel capacity of the IC-OR is reduced compared with that of the classical IC where both receivers know all codebooks. A novel outer bound is derived and shown to be achievable to within a gap for the class of injective semideterministic IC-ORs; the gap is shown to be zero for injective fully deterministic IC-ORs. An exact capacity result is shown for the general memoryless IC-OR when the nonoblivious receiver experiences very strong interference. For the linear deterministic IC-OR that models the Gaussian noise channel at high SNR, nonindependent identically distributed. Bernoulli(1/2) input bits are shown to achieve points not achievable by i.i. d. Bernoulli(1/2) input bits used in the same achievability scheme. For the real-valued Gaussian IC-OR, the gap is shown to be at most 1/2 bit per channel use, even though the set of optimal input distributions for the derived outer bound could not be determined. Toward understanding the Gaussian IC-OR, an achievability strategy is evaluated in which the input alphabets at the nonoblivious transmitter are a mixture of discrete and Gaussian random variables, where the cardinality of the discrete part is appropriately chosen as a function of the channel parameters. Surprisingly, as the oblivious receiver intuitively should not be able to jointly decode the intended and interfering messages (whose codebook is unavailable), it is shown that with this choice of input, the capacity region of the symmetric Gaussian IC-OR is to within 1/2 log (12πe)≈ 3.34 bits (per channel use per user) of an outer bound for the classical Gaussian IC with full codebook knowledge at both receivers.
Caring for Persons with Serious Mental Illness

Abstract This article places evidenced-based knowledge of practice within the social context of care and proposes five policy objectives and specific policy and program changes to address care needs of people with serious mental illness. In spite of demonstration programs that provide the basis for proposed policy initiatives throughout the United States, treatment provision for this population remains inadequate and their safety and well-being continues to be at risk. The authors suggest that treatment initiatives need to be tied to stable policies protecting the mentally ill from adverse social context changes. The authors conclude that policies are needed that will enhance housing assistance, independent social functioning, personal empowerment, and treatment engagement. In addition, efforts are needed to make better use of inpatient hospital care, to better understand the role of assisted treatment, and to better develop consistent long-term fiscal support for the seriously mentally ill. They offer specific policy recommendations for changes in HUD programs, Medicaid and Medicare funding, and treatment programming that address these needs.
Response of Peritoneal Exudate Cells to Brucella melitensis. Influence of Nature of Inflammatory Irritant.∗

Conclusion Studies on mononuclear cell responses to B. melitensis require that attention be paid especially to the nature of inflammatory agent itself when interpreting behavior of the mononuclear cell. The inflammatory substance may so alter mononuclear response as to reverse cytolytic susceptibility of monocytes from normal and immunized animals.
Polyenergetic CT sinogram generator

Energy-sensitive X-ray detection devices operating in photon counting mode are getting growing interest since the last decade. By offering a promise of lower dosage requirements and spectroscopic analysis capabilities, they might redefine the paradigm of clinical X-ray measurements in a near future. A simulation software reproducing the data collection scheme of such detection devices was implemented. Without trying to reproduce the in-depth electronic mechanism of those devices, it is rather oriented toward the overall quality of the measured data in terms of simple detection characteristics. Build upon rugged and proven software components, the generator includes realistic material definitions with respect to energy-dependent attenuation. Projections are measured and features such as energy resolution, number of detected energy levels, counting noise statistics and data weighting schemes are taken into account. Using the proposed method, iterative image reconstructions show that classic beam-hardening related artefacts can successfully be reproduced. The proposed method is intended to be used as a tool aimed at predicting the imaging capabilities of these forthcoming energy-sensitive detection devices and to help in the design of their specifications. Being an easily parameterizable analytical tool, it will also be useful to validate the behavior of new dedicated polyenergetic reconstruction algorithms.
Affective priming for associatively unrelated primes and targets

Affective priming studies showed that responses to targets are faster when they are preceded by a prime with the same affective valence rather than the opposite valence. In virtually all these studies, primes were randomly assigned to different targets, the only restriction being that there should be a predetermined number of affectively congruent and incongruent pairs. One could, however, argue that on average, affectively congruent stimuli tend to be more associatively related than affectively incongruent stimuli. Therefore, randomly constructing affectively congruent and incongruent pairs does not rule out the possibility of a confound between the affective and associative relation between the primes and targets. We conducted a number of studies in which the prime-target pairs were normatively unassociated. Strong affective priming effects were observed in a series of three studies employing an evaluative categorisation task (Experiments 1 & 2), and a lexical decision task (Experiment 3).
Why do women still earn less than men? Decomposing the Dutch gender pay gap, 1996–2006

Despite major improvements in women's labour market attachment, women still earn considerably less than men. International research shows that the persistence of the gender pay gap may be due to the fact that although the gap in characteristics between men and women is diminishing, changes in the wage structure counteract this change. This article will study whether this ‘swimming upstream’ phenomenon is also playing a role in the rather slow convergence between male and female wages in the Netherlands. Our results indicate that this is not the case; most of the changes in the Dutch wage structure have been rather favourable to women. The lacking convergence in wages has to be explained from the fact that despite the favourable changes, the Dutch wage structure still contains a considerable implicit gender bias.
Parallel execution time analysis for least squares problems on distributed memory architectures

In this paper we study the parallelization of PCGLS, a basic iterative method which main idea is to organize the computation of conjugate gradient method with preconditioner applied to normal equations. Two important schemes are discussed. What is the best possible data distribution and which communication network topology is most suitable for solving least squares problems on massively parallel distributed memory computers. A theoretical model of data distribution and communication phases is presented which allows us to give a detail execution time complexity analysis and to investigate its usefulness. It is shown that the implementation of PCGLS, with a row-block decomposition of the coefficient matrix, on a ring of communication structure is the most efficient choice. Performance tests of the developed parallel PCGLS algorithm have been carried out on the massively distributed memory system Parsytec and experimental timing results are compared with the theoretical execution time complexity analysis.
Increased cerebellar volume and BDNF level following quadrato motor training

Using whole-brain structural measures coupled to analysis of salivary brain-derived neurotrophic factor (BDNF), we demonstrate sensory motor training-induced plasticity, including cerebellar gray matter volume increment and increased BDNF level. The increase of cerebellar volume was positively correlated with the increase of BDNF level.
Historical factors that have shaped the evolution of tropical reef fishes: a review of phylogenies, biogeography, and remaining questions

Biodiversity patterns across the marine tropics have intrigued evolutionary biologists and ecologists alike. Tropical coral reefs host 1/3 of all marine species of fish on 0.1% of the ocean’s surface. Yet our understanding of how mechanistic processes have underpinned the generation of this diversity is limited. However, it has become clear that the biogeographic history of the marine tropics has played an important role in shaping the diversity of tropical reef fishes we see today. In the last decade, molecular phylogenies and age estimation techniques have provided a temporal framework in which the ancestral biogeographic origins of reef fish lineages have been inferred, but few have included fully sampled phylogenies or made inferences at a global scale. We are currently at a point where new sequencing technologies are accelerating the reconstruction and the resolution of the Fish Tree of Life. How will a complete phylogeny of fishes benefit the study of biodiversity in the tropics? Here, I review the literature concerning the evolutionary history of reef-associated fishes from a biogeographic perspective. I summarize the major biogeographic and climatic events over the last 65 million years that have regionalized the tropical marine belt and what effect they have had on the molecular record of fishes and global biodiversity patterns. By examining recent phylogenetic trees of major reef associated groups, I identify gaps to be filled in order to obtain a clearer picture of the origins of coral reef fish assemblages. Finally, I discuss questions that remain to be answered and new approaches to uncover the mechanistic processes that underpin the evolution of biodiversity on coral reefs.
Expert position paper on the role of platelet function testing in patients undergoing percutaneous coronary intervention

Optimizing outcomes after percutaneous coronary intervention (PCI) requires balancing between the risks of thrombotic and bleeding events in individual patients.1–3 However, finding the optimal balance is not always straightforward since the risks of thrombotic and bleeding complications may differ extremely between individuals. In addition, the individual effects of anticoagulant and antiplatelet drugs are not uniform in patients.4 Recent European guidelines1,3 recommend the use of prasugrel or ticagrelor instead of clopidogrel in all PCI-treated acute coronary syndrome (ACS) patients without contraindication, acknowledging that laboratory assessment of P2Y12-receptor inhibition may be considered only in selected cases when clopidogrel is used.1 However, there is no guidance with respect to the appropriate methodology and the suggested interpretation of results. The Working Group on Thrombosis of the European Society of Cardiology aimed to review the available evidence and the clinical relevance of platelet function testing in order to reach a consensus regarding the methodology, evaluation, and clinical interpretation of platelet function in patients undergoing PCI. Regarding the choice between available P2Y12-inhibitors, the 2011 ESC guidelines on non-ST segment elevation acute coronary syndromes (NSTE-ACS)1 and the 2012 guidelines on ST-segment elevation myocardial infarction3 recommend prasugrel and ticagrelor for all ACS patients without contraindication, and clopidogrel is only recommended if these agents are not available. Despite the restrictive recommendations for clopidogrel, it still holds a class I indication in ACS due to the large differences in the availability of the new-generation P2Y12-inhibitors among European countries. According to the 2011 ACCF/AHA/SCAI guidelines for PCI,5 a P2Y12-inhibitor should be given for ACS patients without preferring novel P2Y12-inhibitors over clopidogrel. Similarly, the 2012 ACCF/AHA unstable angina/non-ST-segment elevation myocardial infarction guidelines6 and the 2013 ACCF/AHA ST-elevation myocardial infarction guidelines …
TCPSnitch: Dissecting the Usage of the Socket API

Networked applications interact with the TCP/IP stack through the socket API. Over the years, various extensions have been added to this popular API. In this paper, we propose and implement the TCPSnitch software that tracks the interactions between Linux and Android applications and the TCP/IP stack. We collect a dataset containing the interactions produced by more than 120 different applications. Our analysis reveals that applications use a variety of API calls. On Android, many applications use various socket options even if the Java API does not expose them directly. TCPSnitch and the associated dataset are publicly available.
Dynamic analysis of cable-driven parallel mechanisms

A cable-driven parallel mechanism (CDPM) possesses a number of promising advantages over the conventional rigid-link mechanisms, such as simple and light-weight mechanical structure, high-loading capacity, and large workspace. However, the formulations and results obtained for the rigid-link mechanisms cannot be directly applied to CDPMs due to the unilateral property of cables. For a CDPM, dynamic formulation is only valid as actuators exert positive torques. In this paper, cable winding method is studied as it improves the whole dynamic performance of the system. This is followed by dynamic formulation. A generic approach based on dimension reduction technique, which is successfully implemented through a computationally effective recursive algorithm, is proposed to check the existence of positive torques. Since torque optimization problem is modeled in a standard linear programming form, the optimal solution can be efficiently obtained. Two simulation examples are provided to demonstrate the effectiveness of the proposed solution approach
Activity of Glycopeptides against Staphylococcus aureus Infection in a Rabbit Endocarditis Model: MICs Do Not Predict In Vivo Efficacy

ABSTRACT The in vivo efficacy of vancomycin and teicoplanin against five Staphylococcus aureus strains with different susceptibilities to them and methicillin was studied. Rabbits were allocated at random to groups for endocarditis induction with one of these five strains and then treated for 2 days with vancomycin or teicoplanin. Each treated group was compared with a control group infected with the same strain. Vancomycin and teicoplanin showed similar activities. Low MICs did not predict better in vivo results.
Predictors of smoking among US college students.

OBJECTIVES This study explored predictors of smoking among a large, representative national sample of students enrolled in American 4-year colleges. METHODS A sample of undergraduate students, randomly selected from 140 colleges, was sent a detailed questionnaire that included questions about smoking status. RESULTS The 30-day smoking prevalence was 22.3%; 25% of the participants were former smokers. Multivariate analyses suggested that, among college students, men are less likely to smoke than women. In addition, high-risk behaviors (e.g., marijuana use) and lifestyle choices (e.g., nonparticipation in athletics) increased the likelihood of being a smoker. CONCLUSIONS This study's findings have important implications for health education and promotion among college populations.
Domestic Realms, Social Bonds, and Class: Ideologies and Indigenizing Modernity in Dar es Salaam, Tanzania

ResumeDepuis la periode coloniale, les Tanzaniens ont connu plusieurs formes de modernite, et chaque forme s’est concretisee distinctement en modeles d’architecture domestique, de decor interieur et en reseaux sociaux locaux. Cet article, avec pour modeles les habitations et les quartiers des fonctionnaires urbains, explore un processus selon lequel si les structures economiques, de classe, et politico-sociologiques influencent le monde domestique, ces structures en revanche se transforment aussi par les pratiques materielles quotidiennes. Au fur et a mesure que l’economie politique passait du colonialisme au socialisme indigene au liberalisme globalise, les employes de bureaux ont organise des espaces domestiques et des modes de vie dans leurs quartiers, dont chaque modele refletait les facettes de structures anterieures ainsi que les innovations contemporaines. Cet exemple illustre la maniere dont le concept de la modernite peut servir a faire le lien entre les modeles theoriques de structures sociales .
One-carbon metabolism: An aging-cancer crossroad for the gerosuppressant metformin

The gerosuppressant metformin operates as an efficient inhibitor of the mTOR/S6K1 gerogenic pathway due to its ability to ultimately activate the energy-sensor AMPK. If an aging-related decline in the AMPK sensitivity to cellular stress is a crucial event for mTOR-driven aging and aging-related diseases, including cancer, unraveling new proximal causes through which AMPK activation endows its gerosuppressive effects may offer not only a better understanding of metformin function but also the likely possibility of repositioning our existing gerosuppressant drugs. Here we provide our perspective on recent findings suggesting that de novo biosynthesis of purine nucleotides, which is based on the metabolism of one-carbon compounds, is a new target for metformin's actions at the crossroads of aging and cancer.
Efficacy of Intra-Articular Injection of Celecoxib in a Rabbit Model of Osteoarthritis

Introduction: Osteoarthritis is the most common form of arthritis. It is a slowly progressive joint disease typically seen in middle-age to elderly people. Intra-articular injection of hyaluronic acid is a well-documented treatment for knee osteoarthritis. Celebrex® (celecoxib) is a novel nonsteroidal anti-inflammatory drug, which could help to reduce inflammation and to reduce pain. The aim of this study was to evaluate the effects of intra-articular injection of celecoxib in a rabbit osteoarthritis model. Methods: Thirty New Zealand white rabbits underwent unilateral knee joint surgery using the Hulth technique. Six weeks post-surgery, the animals were randomly divided into three groups, and each group was respectively given weekly intra-articular injections with Celebrex®, hyaluronic acid and saline. On the sixth week, the results were assessed in rabbit models by gross observation, histological evaluation, and expression of IL-1β, TNF-α, MMP-3. Results: In the group given Celebrex® and hyaluronic acid, the pathological changes in the rabbit articular cartilage improved significantly, much more than in the saline group. The statistically significant suppression of IL-1β, TNF-α, MMP-3 was shown in the Celebrex group. No significant differences were detected between two treatment groups. Conclusions: Intra-articular injection of celecoxib is beneficial for knee osteoarthritis. It might repair and protect early osteoarthritis cartilage by delaying cartilage degeneration and impairing the function of inflammatory mediators, therefore, intra-articular injection of celecoxib can be used as an alternative to the current treatment of osteoarthritis.
Lattice topological field theory on nonorientable surfaces

The lattice definition of the two-dimensional topological quantum field theory [Fukuma et al., Commun. Math. Phys. 161, 157 (1994)] is generalized to arbitrary (not necessarily orientable) compact surfaces. It is shown that there is a one-to-one correspondence between real associative *-algebras and the topological state sum invariants defined on such surfaces. The partition and n-point functions on all two-dimensional surfaces (connected sums of the Klein bottle or projective plane and g-tori) are defined and computed for arbitrary *-algebras in general, and for the group ring A=R[G] of discrete groups G, in particular.
On Observable Delegation of Personal Data by Watermarking

Privacy in business processes for personalized services is currently a matter of trust, since business processes require the delegation of personal data and users are not able to control their usage and so their delegation. Existing privacy-enhancing technologies like identity management systems consider access control but not the usage of personal data. Current work on usage control mainly considers classification and formalization of usage rules, so called obligations, and the delegation of personal data with a trusted third party (TTP). We investigate on digital watermarking in order to observe the enforcement of obligations for a delegation of personal data without a TTP.
Heparan Sulfate Chain Valency Controls Syndecan-4 Function in Cell Adhesion*

Fibroblasts null for the transmembrane proteoglycan, syndecan-4, have an altered actin cytoskeleton, compared with matching wild-type cells. They do not organize α-smooth muscle actin into bundles, but will do so when full-length syndecan-4 is re-expressed. This requires the central V region of the core protein cytoplasmic domain, though not interactions with PDZ proteins. A second key requirement is multiple heparan sulfate chains. Mutant syndecan-4 with no chains, or only one chain, failed to restore the wild-type phenotype, whereas those expressing two or three were competent. However, clustering of one-chain syndecan-4 forms with antibodies overcame the block, indicating that valency of interactions with ligands is a key component of syndecan-4 function. Measurements of focal contact/adhesion size and focal adhesion kinase phosphorylation correlated with syndecan-4 status and α-smooth muscle actin organization, being reduced where syndecan-4 function was compromised by a lack of multiple heparan sulfate chains.
