QT dispersion and components of the QT interval in ischaemia and infarction.

OBJECTIVE--To evaluate changes in QT dispersion and components of the QT interval in patients admitted with unstable angina and acute myocardial infarction and to study the dynamics of these changes in patients with infarction. METHODS--Prospective study recording electrocardiograms at 50 mm/s in patients admitted with typical cardiac chest pain. Subsequent confirmation of acute myocardial infarction according to standard criteria. Single blind analysis for QT dispersion and QT components using a digitiser and simple computer program. Results are expressed as native QT dispersion, QTc dispersion, and the QT dispersion ratio defined as QT dispersion divided by cycle length and expressed as a percentage. RESULTS--QT dispersion, QTc dispersion, and QT dispersion ratio were all higher in patients with acute myocardial infarction than in those with unstable angina (mean (SD) 66 (18) ms, 75 (26) ms1/2, and 8.1 (2.4)% compared with 38 (13) ms, 39 (13) ms1/2, and 4.5 (1.7) % respectively). Dynamic changes in QTc dispersion were seen after acute infarction with significant differences in the QT components occurring between the different patient groups. Levels of QT dispersion (87 (15) ms), QTc dispersion (105 (17) ms1/2), and QT dispersion ratio (11.7 (0.8)%) in the four patients with ventricular fibrillation were significantly higher. Use of QT dispersion ratio gave a narrower confidence interval. CONCLUSION--QT dispersion is increased after myocardial infarction and levels are higher in patients with ventricular fibrillation. The changes in QT dispersion are dynamic and may reflect the changing pattern of underlying ventricular recovery of ventricular excitability, which is profoundly disturbed in the earliest phase of acute infarction. Expressing QT dispersion as a percentage of cycle length (QT dispersion ratio) rather than using standard rate correction may be superior in identifying patients who develop ventricular fibrillation.
CDD: a database of conserved domain alignments with links to domain three-dimensional structure

The Conserved Domain Database (CDD) is a compilation of multiple sequence alignments representing protein domains conserved in molecular evolution. It has been populated with alignment data from the public collections Pfam and SMART, as well as with contributions from colleagues at NCBI. The current version of CDD (v.1.54) contains 3693 such models. CDD alignments are linked to protein sequence and structure data in Entrez. The molecular structure viewer Cn3D serves as a tool to interactively visualize alignments and three-dimensional structure, and to link three-dimensional residue coordinates to descriptions of evolutionary conservation. CDD can be accessed on the World Wide Web at http://www.ncbi. nlm.nih. gov/Structure/cdd/cdd.shtml. Protein query sequences may be compared against databases of position-specific score matrices derived from alignments in CDD, using a service named CD-Search, which can be found at http://www.ncbi. nlm.nih. gov/Structure/cdd/wrpsb.cgi. CD-Search runs reverse-position-specific BLAST (RPS-BLAST), a variant of the widely used PSI-BLAST algorithm. CD-Search is run by default for protein-protein queries submitted to NCBI's BLAST service at http://www.ncbi. nlm.nih. gov/BLAST.
How Technology Shapes the Actor-Network of Convergence Services: A Case of Mobile Banking

The continuous advancement of mobile technologies offers an opportunity for mobile carriers and banks to offer mobile banking services. However, such convergence of services from mobile carriers and banks raises many complex issues, particularly because it requires alliances among the actors who have different and sometimes conflicting interests. Using the mobile banking sector in Korea, this paper examines how the alliances between mobile carriers, banks, and other related parties are formed, and analyzes how technology affects competition and collaboration among them when a new convergence service is created by two, previously unrelated industries, in this case, by banks and mobile carriers. In so doing, we use the actor– network theory (ANT). As ANT helps analyze how actors form alliances and enroll other actors including nonhuman actors (i.e., technology) to secure their interests through the use of the technology, there is a fit between ANT and the emergence of new, converged services. This paper shows that it is technology that shapes the actor–network of convergence services, and that competition between banks and mobile carriers in mobile banking is about how to inscribe their interests in a given technology and thereby who can translate customers into their own network.
Lo banal como patrimonio de la Costa del Sol. Torremolinos (1959 -1979)

espanolConsiderar patrimonialmente la cultura del ocio en la Costa del Sol supone reconocer como ‘otro’ patrimonio los productos culturales generados por el turismo de ‘sol y playa’ en la Costa del Sol en los anos 60 y 70, tratando como caso paradigmatico de estudio la localidad malaguena de Torremolinos. Desde una concepcion patrimonial alejada de parametros tradicionales, reconocemos a esta localidad por objetos, lugares, edificios, espacios, ambientes y escenarios considerados banales, pero que proponemos como nuevos ‘monumentos’. De esta manera hacemos posible una lectura de la ciudad a traves de distintos archivos de producciones humanas –artisticas, cinematograficas, arquitectonicas, literarias, etc.‑; una especie de analisis estratigrafico que nos permite recomponer una identidad patrimonial incomprendida en su momento, a traves de las diferentes capas de producciones culturales de estas dos decadas de intensa actividad turistica. EnglishConsider as heritage the culture of leisure in Costa del Sol supposes to recognize as ‘another’ heritage the cultural products generated by ‘sun and beach’ tourism on the Costa del Sol in the 60s and 70s, studying as a paradigmatic case the town of Torremolinos (Malaga). From a heritage concept away from traditional parameters, we recognize it through objects, places, buildings, spaces, environments and banal scenes, which propose as new ‘monuments’. In this way we make possible a reading of the city across different human productions ‑artistic, cinematographic, architectural, literary, etc.‑; a kind of stratigraphic analysis that allows us to re‑compose an ununderstood patrimonial identity, through of the different layers of cultural productions of these two decades of intense touristic activity.
Differential Benefit of Statin in Secondary Prevention of Acute Myocardial Infarction according to the Level of Triglyceride and High Density Lipoprotein Cholesterol

Background and Objectives The differential benefit of statin according to the state of dyslipidemia has been sparsely investigated. We sought to address the efficacy of statin in secondary prevention of myocardial infarction (MI) according to the level of triglyceride and high density lipoprotein cholesterol (HDL-C) on admission. Subjects and Methods Acute MI patients (24653) were enrolled and the total patients were divided according to level of triglyceride and HDL-C on admission: group A (HDL-C≥40 mg/dL and triglyceride<150 mg/dL; n=11819), group B (HDL-C≥40 mg/dL and triglyceride≥150 mg/dL; n=3329), group C (HDL-C<40 mg/dL and triglyceride<150 mg/dL; n=6062), and group D (HDL-C<40 mg/dL & triglyceride≥150 mg/dL; n=3443). We evaluated the differential efficacy of statin according to the presence or absence of component of dyslipidemia. The primary end points were major adverse cardiac events (MACE) for 2 years. Results Statin therapy significantly reduced the risk of MACE in group A (hazard ratio=0.676; 95% confidence interval: 0.582-0.785; p<0.001). However, the efficacy of statin was not prominent in groups B, C, or D. In a propensity-matched population, the result was similar. In particular, the benefit of statin in group A was different compared with group D (interaction p=0.042) Conclusion The benefit of statin in patients with MI was different according to the presence or absence of dyslipidemia. In particular, because of the insufficient benefit of statin in patients with MI and dyslipidemia, a different lipid-lowering strategy is necessary in these patients.
Fast deformation of volume data using tetrahedral mesh rasterization

Many inherently deformable structures, such as human anatomy, are often represented using a regular volumetric discretization, e.g., in medical imaging. While deformation algorithms employ discretizations that deform themselves along with the material, visualization algorithms are optimized for regular undeformed discretizations. In this paper, we propose a method to transform highresolution volume data embedded in a deformable tetrahedral mesh. We cast volume deformation as a problem of tetrahedral rasterization with 3D texture mapping. Then, the core of our solution to volume data deformation is a very fast algorithm for tetrahedral rasterization. We perform rasterization as a massively parallel operation on target voxels, and we minimize the number of voxels to be handled using a multi-resolution culling approach. Our method allows the deformation of volume data with over 20 million voxels at interactive rates.
Ontology-Based Service Representation and Selection

Selecting the right parties to interact with is a fundamental problem in open and dynamic environments. The problem is amplified when the number of interacting parties is high, and the parties' reasons for selecting others vary. We examine the problem of service selection in an e-commerce setting where consumer agents cooperate to identify service providers that would satisfy their service needs the most. Previous approaches to service selection are usually based on capturing and exchanging the ratings of consumers to providers. Rating-based approaches have two major weaknesses. (1) ratings are given in a particular context. Even though the context is crucial for interpreting the ratings correctly, the rating-based approaches do not provide the means to represent the context explicitly. (2) The satisfaction criteria of the rater is unknown. Without knowing the expectation of the rater, it is almost impossible to make sense of a rating. We deal with these two weaknesses in two steps. First, we extend a classical rating-based approach by adding a representation of context. This addition improves the accuracy of selected service providers only when two consumers with the same service request are assumed to be satisfied with the same service. Next, we replace ratings with detailed experiences of consumers. The experiences are represented with an ontology that can capture the requested service and the received service in detail. When a service consumer decides to share her experiences with a second service consumer, the receiving consumer evaluates the experience by using her own context and satisfaction criteria. By sharing experiences rather than ratings, the service consumers can model service providers more accurately and, thus, can select service providers that are better suited for their needs.
A neurobiologically informed perspective on psychotherapy

Background Polarisation of biological and psychosocial aspects of psychiatry has promoted a form of Cartesian dualism. Current knowledge of the interaction between biology and psychology makes it possible to consider a truly integrative approach to treatment. Aims The aim of this overview is to consider conceptual models of how psychotherapy may affect the brain. Method The literature discussing the mutual influence of genes and environment is surveyed. Relevant data involving the influence of psychotherapy on the brain are also reviewed. Results Research findings suggest that the brain responds to environmental influence through the alteration of gene expression; that psychotherapy has specific measurable effects on the brain; and that implicit memory may be modified by psychotherapeutic interventions. Conclusions Advances in neuroscience research have led to a more sophisticated understanding of how psychotherapy may affect brain functioning. These developments point the way towards a new era of psychotherapy research and practice in which specific modes of psychotherapy can be designed to target specific sites of brain functioning.
Performance Evaluation of Next Generation Free-Space Optical Communication System

Free-space optical communication systems can provide high-speed, improved capacity, cost effective and easy to deploy wireless networks. Experimental investigation on the next generation free-space optical (FSO) communication system utilizing seamless connection of free-space and optical fiber links is presented. A compact antenna which utilizes a miniature fine positioning mirror (FPM) for high-speed beam control and steering is described. The effect of atmospheric turbulence on the beam angle-of-arrival (AOA) fluctuations is shown. The FPM is able to mitigate the power fluctuations at the fiber coupling port caused by this beam angle-of-arrival fluctuations. Experimental results of the FSO system capable of offering stable performance in terms of measured bit-error-rate (BER) showing error free transmission at 2.5 Gbps over extended period of time and improved fiber received power are presented. Also presented are performance results showing stable operation when increasing the FSO communication system data rate from 2.5 Gbps to 10 Gbps as well as WDM experiments.
Reduced Nicotine Content Cigarettes and Nicotine Patch

Background: Reduced nicotine content (RNC) cigarettes have led to smoking fewer cigarettes, withdrawal relief, and facilitation of cessation. The aim of this study is to examine the effects RNC cigarettes with and without nicotine patch and patch alone on smoking behavior, toxicant exposure, withdrawal discomfort, and as an exploratory analysis, on long-term abstinence. Methods: This study involved a randomized, parallel arm design and six weeks of: (i) 0.05–0.09 mg nicotine yield cigarettes (N = 79); (ii) 21 mg nicotine patch (N = 80), or (iii) 0.05–0.09 nicotine yield cigarettes with 21 mg nicotine patch (N = 76); all groups received six weeks of additional behavioral treatment with follow-ups up to six months. Results: Combination approach led to lower rates of smoking assigned cigarettes and hence lower carbon monoxide levels than RNC cigarettes alone. In addition, the combination approach was associated with less withdrawal severity when switching from usual brand to assigned product, and less smoking of usual brand cigarettes during treatment, but not after treatment compared with the other approaches. Conclusion: Combining very low nicotine content cigarettes with nicotine patch may improve the acute effects resulting from switching to either of these products alone. Impact: These findings may have implications for smoking cessation treatment or a policy measure to reduce nicotine content in cigarettes.

A compact microstrip Yagi antenna is proposed based on the half-mode substrate integrated waveguide (HMSIW) technology. The HMSIW is used to work as the driven element and the magnetic wall is introduced to realize the elements miniaturization of Yagi antenna. Simulated results shows that the total area of the Yagi antenna is 1. 82λ×0. 57λ and the peak gain is about 6.0~7.9 dBi in the 10.5% relative bandwidth.
A Close Approach to Iris Recognition System

Iris recognition, a relatively new biometric technology, has great advantages such as variability, stability and security, thus it is the most promising for high security environments. Among its applications are border control in airports and harbors, access control in laboratories and factories, identification for Automatic Teller Machines and restricted access to police evidence rooms. There have been several implementations of security systems using biometric, especially for identification and verification cases. The term "biometrics" is derived from the Greek words bio (life) and metric (to measure). The pattern used in the biometric is the iris pattern in human eye. The iris pattern has been proved unique for each person. A literature review of the most prominent algorithms implemented in each stage is presented. This paper provides a review of major iris I. Introduction Biometric recognition is an emerging technology which employs the physiological and behavioral characteristics to identify an individual. The physiological characteristics include the iris, fingerprint, face and hand geometry. Voice and signature are categorized as the behavioral characteristics. Among these, the human iris is an annular region between the sclera (the white portion of the eye) and the pupil (the darkest portion of the eye). Iris is gaining lots of attention due its unique pattern. The patterns that give uniqueness to the iris are the coronas, furrows, stripes and so on (1). These patterns thus, distinguish the individual as the genuine and the imposter, and make the iris recognition particularly the promising solution. Iris recognition is a method of biometric authentication that uses pattern-recognition techniques based on high resolution images of the irises of an individual's eyes (16). The main stages of an iris recognition system are: image pre-processing which consists of iris localization, iris normalization; iris feature extraction and template matching (13)(15). It is necessary to obtain the iris region to carry out the feature extraction and the matching. Eyelids and the eyelashes that may cover the iris region are detected and removed. The normalization step is the conversion of Cartesian co-ordinates to the polar co-ordinates. Various image enhancement algorithms can also applied in order to compensate the non uniformity and low contrast characters in the iris portion. Feature extraction is the process of extracting texture from the region of interest and then using these features as parameters for comparing two iris templates. The significant features of the iris are obtained for accurate identification purpose. Template matching compares the user template with the templates from the dataset or the trained dataset using a matching metric. The matching metric will give the measure of similarity between two iris templates. This paper discuses the algorithmic implementation in each stage. Iris image capture stage will not be discussed in this paper. The rest of the stages are discussed next sections including image preprocessing, iris feature extraction and template matching.
MARTUJARRA PREHISTORY: VARIATION IN ARID ZONE ADAPTATIONS

In this paper preliminary results from recent fieldwork in the Little Sandy and Great Sandy Deserts are discussed and placed in the context of other arid zone research. Three points are developed. Firstly, that the arid zone is environmentally diverse and therefore human adaptations within it are likely to be varied in space and through time. Secondly, that a distinction should be made between late Pleistocene and Holocene occupation patterns and finally, that there are changes common to many arid zone sites throughout the Holocene.
Acute and longitudinal changes in motor cortex function following mild traumatic brain injury

Abstract Primary objective: To evaluate excitability and inhibition of the motor cortex acutely and longitudinally following mild traumatic brain injury (mTBI). Research design: A longitudinal paired case-control design was used to examine cortical excitability and inhibition in 15 adults who had sustained an mTBI (mean age = 20.8 ± 1.2 years) and 15 matched control participants (mean age = 21.1 ± 1.3 years). Methods and procedures: Participants visited the lab within 72 hours of injury and again at 1, 2, 4 and 8 weeks post-injury. During each visit, transcranial magnetic stimulation was used to examine resting motor threshold (RMT), motor evoked potential peak-to-peak amplitude (MEPamp) and cortical silent period (CSP) duration of the first dorsal interosseous muscle. Main outcomes and results: There were no differences between groups in RMT (p = 0.10) or MEPamp (p = 0.22) at 72 hours post-injury or across the 2-month testing period (p ≥ 0.68), indicating similar cortical excitability. However, the CSP duration was higher in individuals with mTBI, indicating greater intra-cortical inhibition compared with the control group at 72 hours post-injury (p = 0.03) and throughout the 2 months of recovery (p = 0.009). Conclusions: mTBI appeared to have little effect on cortical excitability, but an acute and long-lasting effect on intra-cortical inhibition.
A test of interventions for security threats from social engineering

– Recently, the role of human behavior has become a focal point in the study of information security countermeasures. However, few empirical studies have been conducted to test social engineering theory and the reasons why people may or may not fall victim, and even fewer have tested recommended treatments. Building on theory using threat control factors, the purpose of this paper is to compare the efficacy of recommended treatment protocols. , – A confirmatory factor analysis of a threat control model was conducted, followed by a randomized assessment of treatment effects using the model. The data were gathered using a questionnaire containing antecedent factors, and samples of social engineering security behaviors were observed. , – It was found that threat assessment, commitment, trust, and obedience to authority were strong indicators of social engineering threat success, and that treatment efficacy depends on which factors are most prominent. , – This empirical study provides evidence for certain posited theoretical factors, but also shows that treatment efficacy for social engineering depends on targeting the appropriate factor. Researchers should investigate methods for factor assessment, and practitioners must develop interventions accordingly.
Face Recognition using 3D Line Edge Map Robust to Expression Changes and Occlusions

We propose new face recognition algorithm using 3D line edge map as combining 3D information on the edge obtained by stereo camera and the conventional line edge map algorithm. As a similarity measure of 3D line edge map, weighted partial and spatially well-localized line segment Hausdorff distance (WPSLHD) is proposed. WPSLHD is a measure which is robust to expression changes, facial occlusions, and depth outliers. The proposed face recognition system performances are evaluated under expression changes and facial occlusions.
The Effect of Task Knowledge Similarity and Distribution on Asynchronous Team Coordination and Performance: Empirical Evidence from Decision Teams

There is agreement in the literature, but little empirical evidence, that team mental models positively influence team coordination and performance. However, most of the empirical evidence on the effects of team mental models are from teams working on real-time (i.e., synchronous) tasks and, to the best of our knowledge, none of the prior studies have taken into account task knowledge distribution within teams. However, most organizational teams work asynchronously (i.e., not always at the same time) and task knowledge distribution varies within teams. Consequently, this study proposes a framework for the study of the effect of team mental models on coordination, and uses this framework to more specifically investigate how two aspects aspect of the team mental model construct—i.e., task knowledge similarity and distribution of task knowledge—influence team coordination and performance. Using data from decision teams, our results suggest that task knowledge similarity has a positive effect on activity coordination and strategy coordination, and that the leader’s task knowledge centrality has a positive effect on strategy coordination. Strategy coordination, in turn, is associated with superior team performance, both in terms of objective financial performance and external board evaluations.
