Supergravity Solutions Dual to Holographic Gauge Theory with External Maxwell Electromagnetic Field

We apply the transformation of mixing azimuthal with wrapped coordinate to the 11D Mtheory with a stack N M5-branes to find the spacetime of a stack of N D4-branes with magnetic field in 10D IIA string theory, after the Kaluza-Klein reduction. With (without) performing the T-duality and taking the near-horizon limit the background becomes the Melvin magnetic field deformed AdS5×S (AdS6×S). We also apply a Lorentz boost on the coordinates of N M5-branes and a transformation of mixing time with wrapped coordinate to obtain the background with inhomogeneously Melvin electric field deformation. Although the found supergravity solutions represent the D-branes under the external Melvin field flux of RR one-form we use a simple observation to see that they are also the solution of Dbranes under the external Maxwell field flux. The relations between using above supergravity solutions and those using other backgrounds in recent by many authors to investigate the holographic gauge theory with external Maxwell electric and magnetic fields through D3/D7 (D4/D8) system are discussed. We also investigate the Wilson loop therein and show that Maxwell magnetic field will increase the quark-antiquark potential and that the Maxwell electric field could increase the quark-antiquark potential only if the direction of quarkantiquark pair does not orthogonal to the electric field.
Code Decomposition: Theory and Applications

In this paper, we give an overview of Seymour's matroid decomposition theory in the context of binary linear codes, and discuss some of its implications for linear programming (LP) decoding of a binary linear code. As shown by Feldman et al. maximum-likelihood (ML) decoding over a discrete memoryless channel can be formulated as an LP problem. Using this formulation, we translate matroid-theoretic results of Grotschel and Truemper from the combinatorial optimization literature as examples of non-trivial families of codes for which ML decoding can be implemented in time polynomial in the length of the code. However, we also show that such families of codes are not good in a coding-theoretic sense - either their dimension or their minimum distance must grow sub-linearly with codelength.
Fault tolerant linear state machines

In this paper, a new method for the design of fault-tolerant linear state machines with initial state 0 and one-dimensional input and one-dimensional output is proposed. It is shown that the LFSR-implementation of the transfer function of a linear automaton can be utilized to correct transient errors in the memory elements. Since the state vector of a linear automaton is uniquely determined by the last n inputs and outputs, a transient error in a memory element can be corrected within n clock cycles by use of the corrected output symbols, where n is the number of components of the state vector. Experimental results have shown that the lowest area overhead can be obtained if the linear state machine is duplicated and a single parity bit is used to distinguish which of the duplicated machines is correct. In this case, an area overhead of 177 % for an 8-bit state vector and 160% for a 256-bit state vector is achieved.
Real-coded evolutionary algorithms with parent-centric recombination

Due to an increasing interest in solving real-world optimization problems using evolutionary algorithms (EAs), researchers have developed a number of real-parameter genetic algorithms (GAs) in the recent past. In such studies, the main research effort is spent on developing an efficient recombination operator. Such recombination operators use probability distributions around the parent solutions to create offspring. Some operators emphasize solutions at the center of mass of parents and some around the parents. We propose a generic parent-centric recombination operator (PCX) and compare its performance with a couple of commonly-used mean-centric recombination operators (UNDX and SPX). With the help of a steady-state, elite-preserving, and computationally fast EA model, simulation results show the superiority of PCX on three test problems.
Joint trajectories of behavioral, affective, and cognitive engagement in elementary school

ABSTRACT The aim of the present study was to model student trajectories of behavioral, affective, and cognitive engagement from Grade 3 to Grade 6. The authors also examined whether teachers perceptions could predict student trajectory membership. The authors collected data from a sample of 831 students and 152 teachers. Using multiple-process growth mixture modeling, they identified 5 distinct trajectories of student engagement. Although a large majority of children presented a stable and high level of engagement on the three dimensions over time, more than one third of them showed a lower or changing level of engagement as the years progressed. These students were more likely to be boys and to be perceived by teachers as being less engaged. They also present more learning or behavioral problems and share less positive relationships with teachers. The results support the need to consider group-based differences when designing and adapting prevention and intervention strategies to favor student engagement.
Monitoring of arterial wall remodelling in atherosclerotic rabbits with a magnetic resonance imaging contrast agent binding to matrix metalloproteinases.

AIMS P947 is a gadolinium-based magnetic resonance imaging (MRI) contrast agent with high affinity for several matrix metalloproteinases (MMPs) involved in arterial wall remodelling. We tested whether the intensity of enhancement detected in vivo in the arterial wall with P947 and MRI correlates with actual tissue MMP-related enzymatic activity measured in a rabbit atherosclerotic model subjected to dietary manipulations. METHODS AND RESULTS Aortas of 15 rabbits in which atherosclerotic lesions were induced by balloon angioplasty and 4 months of hypercholesterolaemic diet were imaged at 'baseline' with P947-enhanced MRI. Atherosclerotic rabbits were divided into three groups: five rabbits were sacrificed ('baseline' group); five rabbits continued to be fed a lipid-supplemented diet ('high-fat' group); and five rabbits were switched from atherogenic to a purified chow diet ('low-fat' group). Four months later, a second P947-enhanced MRI was acquired in the 10 remaining rabbits. A significantly lower signal was detected in the aortic wall of rabbits from the 'low-fat' group as compared with rabbits from the 'high-fat' group (21 ± 6 vs. 46 ± 3%, respectively; P = 0.04). Such differences were not detected with the contrast agent P1135, which lacks the MMP-specific peptide sequence. In addition, the intensity of aortic wall enhancement detected with MRI after injection of P947 strongly correlated with actual MMP-2 gelatinolytic activity measured in corresponding aortic segments using zymography (r = 0.87). CONCLUSION P947-enhanced MRI can distinguish dietary-induced variations in MMP-related enzymatic activity within plaques in an experimental atherosclerotic model, supporting its utility as a clinical imaging tool for in vivo detection of arterial wall remodelling.
Language switching: Exploring writers’ perceptions on the use of their L1s in the L2 writing process

Recent research about L2 writing indicates that L2 writers are likely to instruct themselves on how and what to do during the writing process, using both languages to do so. This constant switch between their L1 and their L2 during their L2 composing process is known as «language-switching» (L-S). The main goals in this qualitative study were two: a) to explore the perceptions these participants have about their L2 composing process and particularly on the use of their L1s in the L2 writing process and b) to depict the perceptions, understandings and tensions these participants have about their personal L2 composing process. The participants in this study were four students in an American university who completed two L2 writing tasks. Data collected included interview transcripts, think aloud protocols (TAPs), reflection sessions, videotapes, students’ written texts and observations. Findings revealed that most participants were aware of the benefits that L-S brought to their L2 writing process. Their L1s helped them organize ideas, write better texts and understand the tasks given. Findings also suggest that L-S seems to be a conscious process for those who use their L2s as a second language, and an unconscious mental process for those who use their L2s as a foreign language. This study also revealed that time frame, prompts, lack of L2 proficiency, and TAPs can influence the participants’ L2 writing process negatively.
Symmetric key injection onto smart cards

This paper describes architectures for securely injecting secret keys onto smart cards. Specifically, this paper details key injection architectures that could be implemented on Personal Identity Verification (PIV) Card in future. The primary goal is to create additional opportunities for the use of the PIV Card in Physical Access Control Systems (PACS). There is significant interest in conducting a fast, accurate, and highly secured authentication transaction using symmetric keys in PACS environments. This paper suggests ways to load site specific symmetric keys onto a PIV Card after the card has been issued, which allows each smart card to share a unique secret key with each PACS with which it interacts. The paper presents four protocols that enable a Card Management System (CMS) to securely load site specific PACS symmetric keys. Each protocol presents unique security characteristics and uses the PIV Card’s card management key in different capacities.
Dynamic DRX Adaptation Algorithm for Elastic Traffic in UMTS Networks

In wireless networks, maximizing throughput and minimizing energy consumption are two conflicting objectives. For elastic flows, it is important to enhance the throughput since it directly affects the quality-ofservice (QoS) of users. At the same time, the energy consumption should be minimized in order to prolong the battery lifetime of the mobile station. In this paper, we propose an adaptive algorithm that adjusts the parameters of the sleep mode operation in Universal Mobile Telecommunications System (UMTS) networks. The proposed algorithm is designed to efficiently tradeoff throughput for energy saving when transferring elastic flows. The extensive simulation results show that the proposed algorithm outperforms the legacy algorithm in terms of user satisfaction which is defined as inversely proportional to the multiplication of service completion time and energy consumption.
Infliximab is a plausible alternative for neurologic complications of Behçet disease

Objective: We evaluated the effectiveness of infliximab in patients with neuro-Behçet syndrome for whom other immunosuppressive medications had failed. Methods: Patients whose common immunosuppressive medications fail in recurrent neuro-Behçet syndrome need an alternative. We report our experience with the tumor necrosis factor α blocker infliximab for long-term treatment of neuro-Behçet syndrome. We recruited patients within a multidisciplinary referral practice of Behçet disease and prospectively followed everyone with a neurologic symptom(s). Patients (n = 16) with ≥2 neurologic bouts (excluding purely progressive disease) while on another immunosuppressive treatment were switched to and successfully sustained on infliximab (5 mg/kg in weeks 0, 2, and 6, then once every 8 weeks; minimum follow-up duration ≥12 months). Infliximab was stopped within 2 months after initiation in one patient because of pulmonary and CNS tuberculosis. Results: Patients had stepwise worsening due to relapses in the Expanded Disability Status Scale modified for neuro-Behçet syndrome before switching to infliximab (median score of 5.0, range 2.0–7.0; median neuro-Behçet syndrome duration 29.1 months, range 5.0–180.7). Median duration of preinfliximab immunosuppressive medication use was 20.0 months (range 3.0–180.7). In all 15 patients, during infliximab treatment (median score 4.0, range 2.0–7.0; median duration 39.0 months, range 16.0–104.9 months), neurologic relapses were completely aborted and there was no further disability accumulation. Conclusion: We observed a significant beneficial effect of infliximab in neuro-Behçet syndrome. Classification of evidence: This study provides Class IV evidence that for patients with neuro-Behçet syndrome whose other immunosuppressive medications failed, infliximab prevents further relapses and stabilizes disability.
The giant molecular cloud associated with RCW 106: A 1.2 mm continuum mapping study

We have mapped the dust continuum emission from the molecular cloud covering a region of 28 pc × 94 pc associated with the well-known H  region RCW 106 at 1.2 mm using SIMBA on SEST. The observations, having an HPBW of 24 �� (0.4 pc), reveal 95 clumps, of which about 50% have MSX associations and only 20% have IRAS associations. Owing to their higher sensitivity to colder dust and higher angular resolution the present observations identify new emission features and also show that most of the IRAS sources in this region consist of multiple dust emission peaks. The detected millimeter sources (MMS) include on one end the exotic MMS5 (associated with IRAS 16183-4958, one of the brightest infrared sources in our Galaxy) and the bright (and presumably cold) source MMS54, with no IRAS or MSX associations on the other end. Around 10% of the sources are associated with signposts of high mass star formation activity. Assuming a uniform dust temperature of 20 K we estimate the total mass of the GMC associated with RCW 106 to be ∼10 5 M� . The constituent millimeter clumps cover a range of masses and radii between 40 to 10 4 Mand 0.3 to 1.9 pc. Densities of the clumps range between (0.5-6) ×10 4 cm −3 . We have decomposed the continuum emission into Gaussian and arbitrary shaped clumps using the two independent structure analysis tools gaussclumps and clumpfind respectively. The clump mass spectrum was found to have an index α of 1.6 ± 0.3, independent of the decomposition algorithm used. The index of the mass spectrum for the mass and length scales covered here are consistent with results derived from large scale CO observations.
Collision Avoidance and Mitigation in Cognitive Wireless Local Area Network over Fibre

Cognitive wireless local area network (WLAN) over fiber (CWLANoF), which employs remote antenna units (RAUs) connected to a central cognitive access point, can provide a cost-effective and efficient architecture for devices to equally share the industrial, scientific, and medical band by taking advantage of cognitive radio capabilities. Based on the CWLANoF architecture, we propose two methods to reduce collisions among WLAN stations, with multiple independent channels operating at each RAU, and transmission and reception diversity through cooperation of adjacent RAUs. We evaluate the proposed methods through Monte-Carlo simulations. Compared with a conventional WLAN Extended Service Set with two access points, the proposed methods achieve 10% gain on Transmission Control Protocol (TCP) throughput and 10~25% reduction on packet error rate of constant-bit-rate traffic streams for spatially uniform traffic. When the traffic is spatially non-uniform with hotspots arising at certain locations, the TCP throughput gain increases by up to 26%. The results show the potential of CWLANoF in coping with dynamic traffic that often occurs in the indoor wireless access.
Design of a novel virtual reality-based autism intervention system for facial emotional expressions identification

A virtual reality (VR)-based system for evaluating facial emotion recognition ability of teenagers with autism spectrum disorders (ASD) is presented. This system is integrated with a non-contact eye tracker that allows investigation of eye gaze and eye physiological indices (e.g., blink rate) of the participants while they seek to identify the emotion displayed by the avatars in the VR environment. Performance and eye data of 12 participants (6 children with ASD and 6 typically developing children) are presented.
A COMPARATIVE ANALYSIS ON: THE SIMILARITIES AND DIFFERENCES OF THE THE PHILOSOPHICAL PERSPECTIVE AND METHODOLOGY ADOPTED IN TWO DIFFERENT QUALITATIVE RESEARCHES

Qualitative research has substantial philosophical dimension difference from quantitative research. Instead of adopting positivism, qualitative research focuses on more interpretivism and Relativism philosophical perspectives. From these two analyzed researches (Local responses to decentralization policy in Indonesia and Two sides of the same coin: Modernity and tradition in Islamic Education in Indonesia) , we learn that both of them put their research stance on interpretivism and constructionism, eventhough they use different methodology. This different methodology emerges because of different focus, goals (objectives), and questions of the research. The Two sides of the same coin uses ethnographic method, while The Local responses adopts interview and official document analysis. Because The Two sides of the same coin adopts ethnographic methodology, it takes one Pesantren as its research site and research it as one whole system. Meanwhile, The Local responses takes six secondary school students to be interviewed. Thus, qualitative researches can be vary depending on research goals (objectives), focus, and problems (questions.
Some Eeciency Results on Seemingly Unrelated Regression Equations

This paper presents some new eeciency results on the seemingly unrelated regression equations model. We consider a two equation seemingly unrelated regression model in which the equations have some common independent variables, and obtain the asymptotic eeciency of the ordinary least squares estimator of a parameter of interest relative to its feasible generalized least squares estimator. The small-sample relative eeciency of the ordinary least squares estimator and the seemingly unrelated unrestricted residuals estimator is also provided.
A Different Perspective on Parallel Sub-Ant-Colonies

In the past, several parallel processing approaches were proposed to speed up the execution of the ant colony optimization. The approaches for parallel runs or multiple colonies usually set the ant number in each run or each colony the same as that in sequential ant colony optimization. In this paper, we revisit the parallel ant colony optimization from a different viewpoint, by partitioning a whole colony into sub-groups and analyze its behavior. An algorithm is proposed and experiments are conducted on the data of a traveling salesman problem to show the effectiveness of the proposed approach.
Chromosome 5p Region SNPs Are Associated with Risk of NSCLC among Women

In a population-based case-control study, we explored the associations between 42 polymorphisms in seven genes in this region and non-small cell lung cancer (NSCLC) risk among Caucasian (364 cases; 380 controls) and African American (95 cases; 103 controls) women. Two TERT region SNPs, rs2075786 and rs2853677, conferred an increased risk of developing NSCLC, especially among African American women, and TERT-rs2735940 was associated with a decreased risk of lung cancer among African Americans. Five of the 20 GHR polymorphisms and SEPP1-rs6413428 were associated with a marginally increased risk of NSCLC among Caucasians. Random forest analysis reinforced the importance of GHR among Caucasians and identified AMACR, TERT, and GHR among African Americans, which were also significant using gene-based risk scores. Smoking-SNP interactions were explored, and haplotypes in TERT and GHR associated with NSCLC risk were identified. The roles of TERT, GHR, AMACR and SEPP1 genes in lung carcinogenesis warrant further exploration.
Effects of Charitable Versus Monetary Incentives on the Acceptance of and Adherence to a Pedometer-Based Health Intervention: Study Protocol and Baseline Characteristics of a Cluster-Randomized Controlled Trial

Background Research has so far benefited from the use of pedometers in physical activity interventions. However, when public health institutions (eg, insurance companies) implement pedometer-based interventions in practice, people may refrain from participating due to privacy concerns. This might greatly limit the applicability of such interventions. Financial incentives have been successfully used to influence both health behavior and privacy concerns, and may thus have a beneficial effect on the acceptance of pedometer-based interventions. Objective This paper presents the design and baseline characteristics of a cluster-randomized controlled trial that seeks to examine the effect of financial incentives on the acceptance of and adherence to a pedometer-based physical activity intervention offered by a health insurance company. Methods More than 18,000 customers of a large Swiss health insurance company were allocated to a financial incentive, a charitable incentive, or a control group and invited to participate in a health prevention program. Participants used a pedometer to track their daily physical activity over the course of 6 months. A Web-based questionnaire was administered at the beginning and at the end of the intervention and additional data was provided by the insurance company. The primary outcome of the study will be the participation rate, secondary outcomes will be adherence to the prevention program, physical activity, and health status of the participants among others. Results Baseline characteristics indicate that residence of participants, baseline physical activity, and subjective health should be used as covariates in the statistical analysis of the secondary outcomes of the study. Conclusions This is the first study in western cultures testing the effectiveness of financial incentives with regard to a pedometer-based health intervention offered by a large health insurer to their customers. Given that the incentives prove to be effective, this study provides the basis for powerful health prevention programs of public health institutions that are easy to implement and can reach large numbers of people in need.
Willingness to pay for voluntary health insurance in Tanzania.

OBJECTIVE(S) To assess how willing people would be to join a voluntary health insurance scheme and to see how they respond to changes in the benefit package. We also examined willingness to cross-subsidise the poor. DESIGN Cross-sectional study. SUBJECTS Two thousand two hundread and twenty four households comprising of 1,163 uninsured household heads asked about their willingness to pay for insurance in seven districts/councils (three urban and four rural) and 1,061 insured households were asked about their willingness to pay for insurance premiums for the poor in their community. Uninsured respondents were presented with two scenarios, the first reflected the current design of the Community Health Fund/Tiba Kwa Kadi (CHF/TIKA), the second offered expanded benefits, and included inpatient care in public facilities and transport. RESULTS Only 30% of uninsured rural households were willing to pay more than Tsh 5,000 the current premium level, their average amount was Tsh 10,741, while in urban areas one percent of households were willing to pay more than Tsh 5,000. There was very limited willingness to pay more than 5,000 Tsh, even with an expanded package in rural areas. Household from rural areas were more willing to cross-subsidise the poor, but contribution levels were higher in urban areas. CONCLUSION Communities need to be sensitised about the existence of the CHF/TIKA to encourage enrollment. Expanding the benefit package would further increase enrollment. However, few people would be willing to pay more than the current premium.
