MEANDERING DIPOLE ANTENNA FOR PASSIVE UHF RFID APPLICATION

RFID is very challenging area in today's world. The basic elements of RFID system are reader and tag. The main element of the RFID system is TAG antenna. Most of the UHF RFID tags have to be connected to very small objects so it is essential that the tag antenna should be miniaturized without degrading the radiation efficiency. There are various techniques to miniaturize antenna means reduce the size of antenna. But this work mainly focuses on meandering technique. In meandering technique it requires single or multiple folds of radiating body. Here the arms of the dipole are folded to reduce the size of antenna without affecting the radiation efficiency. The meandering dipole antenna is designed and simulated in IE3D software.
Emotionality differences between a native and foreign language: theoretical implications

A growing literature examines how affective processing may be weaker in a foreign language than in a native language. This article reviews mechanisms that could underlie this effect and then delves into practical implications. The most common category of explanations is that emotional resonances in the discourse context accrue to utterances because human memory is inherently associative. One application concerns forensic investigations. Compared to emotional phrases in a native language, emotional phrases heard or read in a foreign language elicit weaker skin-conductance responses (SCRs). In one study involving a mock crime, SCRs elicited by a foreign language were high and insensitive to emotionality, suggesting a stress response. A second application is decision making, given recent findings that judgments in a foreign language are influenced by emotional content. This raises the question of how to assess the real-world importance of this provocative laboratory finding. A third application is the emotional and logical appeal of advertising slogans. In multilingual regions, marketers could direct appeals to consumers in their native language to sell luxury items. In contrast, ads using a less proficient or foreign language may be most effective for selling items that will increase work productivity.
Self-Regulated Learning in Accounting: Diagnosis, Dimensions and Explanations

This research analyzes self-regulated learning in Accounting students in two public universities, presenting diagnosis, dimensions and possible explanations, contextualized from the gender, age and stage in the course. The objectives of this paper include to: (a) identify the self-regulated learning strategies used by Accounting students in two public universities, (b) determine the dimensions associated with those strategies, and (c) analyze how these strategies could be explained on the basis of gender, age or stage (semester) of the students in the course. A sample consisting of 249 individuals revealed that gender and age are factors that influence the degree of self-regulation of a student. Women and younger students tend to have higher levels of self-regulated learning, however, in the stage analysis, the results did not show normal distribution, thus demonstrating the impossibility of realizing the increase or decrease of the degree of self-regulated learning among respondents. These results contribute to the practice of teaching accounting, as older students and those with a male gender should receive more special attention in relation to their development of self-regulated, independent and proactive learning.
A Shadow Cursor for Calibrating Screen Coordinates of Tabletop Displays and Its Evaluation

SUMMARY This paper discusses the use of a common computer mouse as a pointing interface for tabletop displays. In the use of a common computer mouse for tabletop displays, there might be an angular distance between the screen coordinates and the mouse control coordinates. To align those coordinates, this paper introduces a screen coordinates calibration technique using a shadow cursor. A shadow cursor is the basic idea of manipulating a mouse cursor without any visual feedbacks. The shadow cursor plays an important role in obtaining the angular distance between the two coordinates. It enables the user to perform a simple mouse manipulation so that screen coordinates calibration will be completed in less than a second. key words: shadow cursor, screen coordinates calibration, tabletop display
Paternal mtDNA and Maleness Are Co-Inherited but Not Causally Linked in Mytilid Mussels

Background In marine mussels of the genus Mytilus there are two mitochondrial genomes. One is transmitted through the female parent, which is the normal transmission route in animals, and the other is transmitted through the male parent which is an unusual phenomenon. In males the germ cell line is dominated by the paternal mitochondrial genome and the somatic cell line by the maternal. Research to date has not allowed a clear answer to the question of whether inheritance of the paternal genome is causally related to maleness. Methodology/Principal Findings Here we present results from hybrid crosses, from triploid mussels and from observations of sperm mitochondria in fertilized eggs which clearly show that maleness and presence of the paternal mitochondrial genome can be decoupled. These same results show that the female mussel has exclusive control of whether her progeny will inherit the mitochondrial genome of the male parent. Conclusions/Significance These findings are important in our efforts to understand the mechanistic basis of this unusual mode of mitochondrial DNA inheritance that is common among bivalves.
Coping with Type 2 Diabetes

Abstract OBJECTIVE-The aim of this study was to identify the coping methods of adults with type 2 diabetes, explore whether patient race (African-American vs. white, non-Latino) and gender (female vs. male) influenced coping style, and then analyze the relationship between coping and self-assessed diabetic control (self-management success). RESEARCH DESIGN AND METHODS-From an exploratory research design using a mixed-methodological approach, in-depth interviews were conducted with 34 interviewees-9 black females, 5 black males, 15 white females, and 5 white males-living in a large mid-South city. Interviews were audio-taped, transcribed, then unitized and codified for analysis. RESULTS-Interviewees reported 136 strategies, collapsed into 40 distinct coping methods. Race and gender differences first were observed in the frequency distributions of methods. Whites reported significantly more problem-focused methods than African-Americans. Males reported, overall, fewer methods, less emotion-focused, yet more problem-focused methods than females. Interviewees reporting emotion-focused methods were less likely to report problem-focused methods. Emotion-focused coping was associated with poorer self-assessed diabetic control; problem-focused coping was associated with better control. CONCLUSIONS-Findings suggest that adults with type 2 diabetes use a variety of coping methods, with their basic coping styles influenced by race and gender. This study also demonstrated the usefulness of the problem/emotion-focused dichotomy as a coping method classification system and how these basic styles correlate with interviewees' diabetic control. Lastly, findings emphasize the complexity and importance of psychosocial coping in diabetes and the need for greater attention by clinicians and researchers.
Gemcitabine and oxaliplatin combination chemotherapy in advanced biliary tract cancers.

BACKGROUND Biliary tract cancers are uncommon tumors with a poor prognosis and most patients present with invasive and inoperable disease at diagnosis. Chemotherapy represents a palliative treatment, with poor response rates and a median survival of less than 6 months. Oxaliplatin and gemcitabine have shown an interesting activity as single agents in this group of patients. PATIENTS AND METHODS We carried out a multicenter phase II study to evaluate the efficacy and safety of combined oxaliplatin and gemcitabine in locally advanced and metastatic biliary tract carcinoma. The schedule of chemotherapy included oxaliplatin 100 mg/m(2) on day 1 and gemcitabine 1000 mg/m(2) on days 1 and 8, every 21 days. RESULTS All the 24 patients were evaluable for response and toxicity. According to RECIST criteria we observed one complete response and 11 partial responses for an overall response rate of 50%. Overall survival for all the patients on study was 12 months (range 2-30). According to WHO criteria, three patients (12.5%) suffered grade 3 neutropenia and three patients (12.5%) grade 3 thrombocytopenia. Only two patients (8%) suffered grade 3 neuropathy. CONCLUSIONS Oxaliplatin and gemcitabine chemotherapy seems to be effective with a favorable safety profile in first-line chemotherapy of advanced biliary tract cancers.
Does source memory impairment associated with emotionally arousing stimuli occur at encoding or retrieval?

The present experiment investigated whether negatively arousing stimuli produce source memory impairment and whether the impairment occurs at encoding or retrieval. Participants were presented with negatively arousing, positively arousing, and neutral pictures. Each picture was followed by an instructional slide that indicated whether the picture was an Apple-kind or an Orange-kind. Item memory was assessed by free recall and source memory was assessed by asking participants to classify the recalled pictures into the two kinds of pictures. The results indicated that item memory was greater for the negatively arousing pictures than for the positively arousing and the neutral pictures. However, the negatively arousing pictures produced more misattribution errors than the neutral pictures, replicating source memory impairment. It was concluded that source memory impairment associated with negatively arousing stimuli occurs at encoding.
Redrawing the Ramachandran plot after inclusion of hydrogen-bonding constraints

A protein backbone has two degrees of conformational freedom per residue, described by its φ,ψ-angles. Accordingly, the energy landscape of a blocked peptide unit can be mapped in two dimensions, as shown by Ramachandran, Sasisekharan, and Ramakrishnan almost half a century ago. With atoms approximated as hard spheres, the eponymous Ramachandran plot demonstrated that steric clashes alone eliminate ¾ of φ,ψ-space, a result that has guided all subsequent work. Here, we show that adding hydrogen-bonding constraints to these steric criteria eliminates another substantial region of φ,ψ-space for a blocked peptide; for conformers within this region, an amide hydrogen is solvent-inaccessible, depriving it of a hydrogen-bonding partner. Yet, this “forbidden” region is well populated in folded proteins, which can provide longer-range intramolecular hydrogen-bond partners for these otherwise unsatisfied polar groups. Consequently, conformational space expands under folding conditions, a paradigm-shifting realization that prompts an experimentally verifiable conjecture about likely folding pathways.

Hyperventilation and exhaustion syndrome

Chronic stress is among the most common diagnoses in Sweden, most commonly in the form of exhaustion syndrome (ICD-10 classification – F43.8). The majority of patients with this syndrome also have disturbed breathing (hyperventilation). The aim of this study was to investigate the association between hyperventilation and exhaustion syndrome. Thirty patients with exhaustion syndrome and 14 healthy subjects were evaluated with the Nijmegen Symptom Questionnaire (NQ). The participants completed questionnaires about exhaustion, mental state, sleep disturbance, pain and quality of life. The evaluation was repeated 4 weeks later, after half of the patients and healthy subjects had engaged in a therapy method called ‘Grounding’, a physical exercise inspired by African dance. The patients reported significantly higher levels of hyperventilation as compared to the healthy subjects. All patients’ average score on NQ was 26.57 ± 10.98, while that of the healthy subjects was 15.14 ± 7.89 (t = −3.48, df = 42, p < 0.001). The NQ scores correlated strongly with two measures of exhaustion (Karolinska Exhaustion Scale KES r = 0.772, p < 0.01; Shirom Melamed Burnout Measure SMBM r = 0.565, p < 0.01), mental status [Hospital Anxiety and Depression Score (HADS) depression r = 0.414, p < 0.01; HADS anxiety r = 0.627, p < 0.01], sleep disturbances (r = −0.514, p < 0.01), pain (r = −.370, p < 0.05) and poor well-being (Medical Outcomes Survey Short Form 36 questionnaire- SR Health r = −0.529, p < 0.05). In the logistic regression analysis, the variance in the scores from NQ were explained to a high degree (R2 = 0.752) by scores in KES and HADS. The brief Grounding training contributed to a near significant reduction in hyperventilation (F = 2.521, p < 0.124) and to significant reductions in exhaustion scores and scores of depression and anxiety. The conclusion is that hyperventilation is common in exhaustion syndrome patients and that it can be reduced by systematic physical therapy such as Grounding.
Towards a UML Profile for Model-Driven Object-Relational Mapping

By using UML (Unified Modeling Language) and ER (Entity Relationship) notations to describe a system, the specification of persistent and transient details became separated. UML and ER models use distinct notations, that cannot be checked for consistence, and therefore are not suitable to be used in a model driven development approach. This paper proposes a synergistic approach to persistence modeling by extending UML with a profile that represents object-relational mapping concepts, and provides rules to check the coherence between persistence and object oriented concepts. Model driven transformations are proposed, and implemented by a tool, in order to turn models into object relational mapped systems based upon the JPA (Java Persistence API) standard.
Propagation measurements and models for wireless communications channels

The authors describe the type of signals that occur in various environments and the modeling of the propagation parameters. Models are essentially of two classes. The first class consists of parametric statistical models that on average describe the phenomenon within a given error. They are simple to use, but relatively coarse. In the last few years a second class of environment-specific models has been introduced. These models are of a more deterministic nature, characterizing a specific street, building, etc. They are necessarily more time consuming to use, but are also more revealing concerning physical details and hopefully more accurate. Some key parameters and the measurement of them are discussed and then the different wireless environments are treated. The latter topic is divided into outdoor environments, indoor environments, and radio penetration from outdoor to indoor environments. >
Sound Localization Under Perturbed Binaural Hearing

This paper reports on the acute effects of a monaural plug on directional hearing in the horizontal (azimuth) and vertical (elevation) planes of human listeners. Sound localization behavior was tested with rapid head-orienting responses toward brief high-pass filtered (>3 kHz; HP) and broadband (0.5-20 kHz; BB) noises, with sound levels between 30 and 60 dB, A-weighted (dBA). To deny listeners any consistent azimuth-related head-shadow cues, stimuli were randomly interleaved. A plug immediately degraded azimuth performance, as evidenced by a sound level-dependent shift ("bias") of responses contralateral to the plug, and a level-dependent change in the slope of the stimulus-response relation ("gain"). Although the azimuth bias and gain were highly correlated, they could not be predicted from the plug's acoustic attenuation. Interestingly, listeners performed best for low-intensity stimuli at their normal-hearing side. These data demonstrate that listeners rely on monaural spectral cues for sound-source azimuth localization as soon as the binaural difference cues break down. Also the elevation response components were affected by the plug: elevation gain depended on both stimulus azimuth and on sound level and, as for azimuth, localization was best for low-intensity stimuli at the hearing side. Our results show that the neural computation of elevation incorporates a binaural weighting process that relies on the perceived, rather than the actual, sound-source azimuth. It is our conjecture that sound localization ensues from a weighting of all acoustic cues for both azimuth and elevation, in which the weights may be partially determined, and rapidly updated, by the reliability of the particular cue.
Cultural sport psychology research: conceptions, evolutions, and forecasts

Cultural sport psychology (CSP) is a relatively new research genre that challenges mainstream sport psychology's assumptions to facilitate contextualized understandings of marginalized topics and cultural identities. Conceptual writings on CSP have grown in the past 10 years, and with that, empirical literature explicitly positioned within CSP. In this article, the landscape of CSP is outlined to more clearly explicate and contextualize the goals and tenets of this mode of inquiry, with the overarching intent of making further recommendations for CSP research. As CSP is broad, a small body of sport research conducted on race and ethnicity (two facets of cultural identity) is reviewed. Suggestions are made to extend the limited body of research on marginalized cultural identities via a CSP approach, focusing on reflexive processes and participant engagement. Through these strategies, CSP research is put forward as a way to further open the possibility of advancing social change and social justice.
Economic Evolution of National Systems

The idea that biology rather than physics provides the proper model for economics is a constantly recurring one. There is an increased concern with dynamics, competitiveness, and innovation which appear to be important elements in generating the increased interest in the evolutionary model of economic behavior. The first part of this article briefly addresses conceptual issues, and argues that the basic unit of analysis should be “national systems of political economy. ” Next, I analyze and compare the American and Japanese economies. Finally, I set forth a few speculations about whether or not one can evaluate these systems in evolutionary terms. My conclusion is that while evolutionary theory is a promising and fascinating approach to the study of economic systems, it is not yet a satisfactory one.
New approach for routing in mobile ad-hoc networks based on ant colony optimisation with global positioning system

The field of mobile ad-hoc networks (MANETs) has gained an important part of the interest of researchers and become very popular in past few years. MANETs can be used to set up a temporary mean of communication by having nodes behave as hosts and routers, with packets hopping between nodes to reach the destination node. This makes MANET suitable for rapid deployment, but because of the dynamic changes in network configurations, quickly finding the optimum route is difficult. In this study, the authors propose a biology-inspired ant routing protocol based on ant colony optimisation called as optimised antnet global positioning system, which is based on GPS and mobile software agents modelled on ants for routing in ad-hoc networks. The authors compare the performance of the authors protocol with Antnet, ad-hoc on-demand distance vector, Dynamic Source Routing (DSR) and Ad-hoc On Demand Multipath Distance Vector (AOMDV) protocols with respect to end-to-end delay, average throughput, packet delivery ratio and route cost.
Accelerated Sparse Linear Regression via Random Projection

In this paper, we present an accelerated numerical method based on random projection for sparse linear regression. Previous studies have shown that under appropriate conditions, gradient-based methods enjoy a geometric convergence rate when applied to this problem. However, the time complexity of evaluating the gradient is as large as $\mathcal{O}(nd)$, where $n$ is the number of data points and $d$ is the dimensionality, making those methods inefficient for large-scale and high-dimensional dataset. To address this limitation, we first utilize random projection to find a rank-$k$ approximator for the data matrix, and reduce the cost of gradient evaluation to $\mathcal{O}(nk+dk)$, a significant improvement when $k$ is much smaller than $d$ and $n$. Then, we solve the sparse linear regression problem via a proximal gradient method with a homotopy strategy to generate sparse intermediate solutions. Theoretical analysis shows that our method also achieves a global geometric convergence rate, and moreover the sparsity of all the intermediate solutions are well-bounded over the iterations. Finally, we conduct experiments to demonstrate the efficiency of the proposed method.
Variable Dopamine Release Probability and Short-Term Plasticity between Functional Domains of the Primate Striatum

Release of the neuromodulator dopamine (DA) is critical to the control of locomotion, motivation, and reward. However, the probability of DA release is not well understood. Current understanding of neurotransmitter release probability in the CNS is limited to the conventional synaptic amino acid transmitters (e.g., glutamate and GABA). These fast neurotransmitters are released with a repertoire of probabilities according to synapse type, and these probabilities show activity-dependent plasticity according to synapse use. Synapses for neuromodulators such as DA, however, are designed for signaling that diverges temporally and spatially from that for fast neurotransmitters: DA receptors are exclusively metabotropic and at sites that extend to extrasynaptic locations and neighboring synapses. In this study, the release probability of DA was explored in real time in limbicversus motor-associated functional domains of the striatum of a primate (marmoset; Callithrix jacchus) using fast-scan voltammetry at a carbon-fiber microelectrode. We show that the probability of axonal DA release varies with striatal domain. Furthermore, release probability exhibits a short-term, activity-dependent plasticity that ranges from depression to facilitation in motor-through limbic-associated regions, respectively. Rapid plasticity does not result from metabotropic D2-like DA receptor activation or ionotropic GABAA receptor effects but is dependent on Ca2+ availability. These data reveal that rapid dynamics in DA release probability will participate in the transmission of the patterns and frequencies encoded by DA neuron action potential discharge. Furthermore, the regional variation in these features indicates that limbic-versus motor-associated DA neurons are permitted to generate diverse DA signals in response to a given firing pattern.
