Creating a Multimedia Extension for Tcl Using the Java Media Framework

As multimedia capable computers become cheaper and more pervasive in the consumer and corporate markets, and as the availability of digital information increases, the need for low-cost, cross-platform multimedia applications will steadily rise. However, because Tcl lacks native support for continuous media streams, such as audio, video, and animation, it is not well suited for this emerging application domain. At the same time, Java now provides a set of class libraries, called the Java Media Framework (JMF), which provides the multimedia support that Tcl lacks. With the recently introduced integration of Tcl and Java, Java can now be used to provide the cross-platform multimedia support required by Tcl; whereas Tcl can be used to provide the easy-touse programming environment required for building multimedia applications. In this paper, we introduce a Tcl extension that provides a high-level scripting interface to the Java Media Framework. In addition, we will highlight some interesting problems in the current Tcl/Java package as well as suggest some potential solutions. This paper will benefit Tcl programmers who would like to learn more about using Tcl to build multimedia applications, integrating Tcl and Java, or the multimedia support provided by the JMF.
Generation of AES-Like S-Boxes by Replacing Affine Matrix

AES type S-boxes are constructed by replacing the affine matrix of AES S-box equation with 8x8 invertible affine matrices. The 8x8 S-boxes of AES produced in GF (28) are a nonlinear transformation that have significant effect on the strength of entire system. In this paper, 46 AES like S-boxes are generated by replacing the affine matrix and only 10 randomly selected S-boxes are included. The cryptographic properties of 10 AES like S-boxes are analyzed. The S-box must satisfy these properties in order to yield a secure and reliable cipher. These include: Avalanche, Strict Avalanche, Bit Independence criteria and Non-linearity measurement. The experimental results indicate that most of the generated S-boxes mimic the AES original S-box with respect to these properties and some of them are stronger than AES S-box.

Tongxinluo Improves Cardiac Function and Ameliorates Ventricular Remodeling in Mice Model of Myocardial Infarction through Enhancing Angiogenesis

Background. Myocardial infarction (MI) is a major cause of morbidity and mortality in the world. Tongxinluo (TXL) is a traditional Chinese compound prescription which has cardioprotective functions. The present study was aimed to determine the effect of TXL on postischemic cardiac dysfunction and cardiac remodeling and to elucidate the underlying mechanisms. Methods and Results. MI was performed by ligation of left anterior descending coronary artery (LAD) in male adult mice. Mice were randomly divided into four groups: (1) sham group (Sham); (2) MI-control group (Control); (3) MI-low dose TXL group (TXL-L); and (4) MI-high dose TXL (TXL-H) group. Compared with the control group, TXL treatment restored cardiac function, increased revascularization, attenuated cardiomyocyte apoptosis, and reduced interstitial fibrosis. TXL treatment increased the phosphorylation of Akt, extracellular signal regulated kinase (ERK), and endothelial nitric oxide synthase (eNOS); the expression of phosphatidylinositol3-kinase (PI3K), hypoxia-inducible factors 1α (HIF-1α), and vascular endothelial growth factor (VEGF); and the DNA binding activity of HIF-1α after MI. Conclusion. TXL may improve cardiac function and ameliorate cardiac remodeling by increasing neovascularization through enhancing the phosphorylation of Akt and ERK, the expression and activity of HIF-1α, and the protein level of VEGF and p-eNOS.
Significant event audit in practice: a preliminary study.

BACKGROUND While well described and promoted as a useful activity, there remains a paucity of evidence on the process and experience of significant event audit (SEA) in primary care. To date, the most comprehensive evaluation of the process has been produced by comparing SEA with conventional audit. The current study intends to contribute to the debate by examining the attitudes and perceptions of a range of primary care staff who have been involved in the process. OBJECTIVES The aim of this study was to identify participants' perceptions of the benefits and problems associated with SEA in the context of primary care, and to derive suggestions which might improve the process of SEA. METHODS Semi-structured interviews of 12 participants from a variety of primary care disciplines were conducted, using grounded theory to analyse the results. RESULTS A set of six perceptions and seven recommendations for the facilitation of SEA were produced. CONCLUSIONS SEA constitutes a powerful tool, which can contribute to team building, enhanced communication and improved patient care, and represents a vital contributor to the development of clinical governance in primary care. However, its implementation and sustenance require sensitive handling for optimal benefit and to minimize difficulties. Our research has enabled us to propose suggestions to facilitate these processes.

different digestive diseases, such as gastritis, gastric and duodenal ulcer, and mucosa-associated changes to lymphoma and gastric cancer in adults.1 The reasons for developing one or another disease are not well understood and several factors are possibly involved.2 Some virulence genes of H. pylori infection, CagA and VacA, have been shown to influence the clinical outcome of infection in adults.3,4 H
An evolutionary subspace clustering algorithm for high-dimensional data

We present an algorithm for generating subspace clusterings of large data sets with many attributes. An evolutionary algorithm is used to form groups of relevant attributes. Those groups are replaced by their centroids, making it possible to cluster the objects in a much lower dimensional space. Preliminary experiments with scalable synthetic data sets suggest that the algorithm generates competitive clusterings while scaling quite well.
Rapid modeling and efficient characterization of shielded oval-shaped spiral inductors

A rapid CAD technique is presented for accurately modeling oval (stadium) shaped inductors with various shielding schemes, which features rapid simulation speed (in the range of few seconds per spiral) and significantly enhanced capacity compared to conventional electromagnetic simulation tools. Inaccuracies inherent in popular measurement and de-embedding methods are discussed and effectively factored out by using the proposed modeling approach to include polysilicon shield patterns and interconnect leads to the device model. The proposed technique is found to yield a model to measurement correlation averaging 2.9% in low frequency inductance and 3% in self-resonance frequency, for an array of inductors fabricated in an 180nm 5-metal CMOS process.
Stability of VISCOUS flow in a curved channel WITH radial temperature gradient

In this paper, the stability of Dean’s problem in the presence of a radial temperature gradient is studied for narrow gap case. The analytical solution of the eigen value problem is obtained by using the Galerkin’s method. The critical values of parameters and Λ are computed, where is wave number and Λ is a parameter determining the onset of stability from the obtained analytical expressions for the first, second and third approximations. It is found that the difference between the numerical values of critical Λ corresponding to the second and third approximations is very small as compared to the difference between first and second approximations. The critical values of Λ obtained by the third approximation agree very well with the earlier results computed numerically by using the finite difference method. This clearly indicates that for the better result one should obtain the numerical values by taking more terms in approximation. Also, the amplitude of the radial velocity and the cell-patterns are shown on the graphs for different values of the parameter M, which depends on difference of temperatures of outer cylinder to the inner one i.e. on , where is the temperature of inner cylinder and is the temperature of outer cylinder.
A velocity-preserving trajectory simplification approach

By the rise of mobile devices, trajectory data could be easily collected and used in several applications, like destination prediction, public transportation optimization, and travel route recommendation. However, due to the spatio-temporal nature, raw trajectory data usually contain redundant movement information. This observation motivates the trajectory simplication approaches which discard some points with preserving some specific features, such as position features, direction features, and so on. Most of existing simplifications ignore the importance of velocity features. This paper proposes an adaptive trajectory approaches while taking the velocity feature into account. Specifically, the Adaptive Trajectory Simplification (ATS) algorithm is proposed, which not only preserves the position feature, but the velocity feature from the given trajectories. ATS algorithm groups the velocity values into several intervals, which are used to partition trajectories into velocity-preserving segments. The simplified trajectory could be derived by applying the position-preserving simplification approach on each segment, where the threshold in a position-preserving approach could be determined without manual setting. Extensive experiments are conducted by using a real trajectory dataset in Porto. The experimental results show ATS algorithm could simplify trajectories effectively while preserving the velocity feature and the position feature at the same time.
Tablet-based activity schedule for children with autism in mainstream environment

Including children with Autism Spectrum Disorders (ASD) in mainstreamed environments creates a need for new interventions whose efficacy must be assessed in situ. This paper presents a tablet-based application for activity schedules that has been designed following a participatory design approach involving mainstream teachers, special-education teachers and school aides. This applications addresses two domains of activities: classroom routines and verbal communications. We assessed the efficiency of our application with a study involving 10 children with ASD in mainstream inclusion (5 children are equipped and 5 are not equipped). We show that (1) the use of the application is rapidly self-initiated (after two months for almost all the participants) and that (2) the tablet-supported routines are differently executed over time according to the activity domain conditions. Importantly, compared to the control children, the equipped children exhibited more classroom and communication routines correctly performed after three month of intervention.
Autonomous Quality Control of Joint Orientation Measured with Inertial Sensors

Clinical mobility assessment is traditionally performed in laboratories using complex and expensive equipment. The low accessibility to such equipment, combined with the emerging trend to assess mobility in a free-living environment, creates a need for body-worn sensors (e.g., inertial measurement units—IMUs) that are capable of measuring the complexity in motor performance using meaningful measurements, such as joint orientation. However, accuracy of joint orientation estimates using IMUs may be affected by environment, the joint tracked, type of motion performed and velocity. This study investigates a quality control (QC) process to assess the quality of orientation data based on features extracted from the raw inertial sensors’ signals. Joint orientation (trunk, hip, knee, ankle) of twenty participants was acquired by an optical motion capture system and IMUs during a variety of tasks (sit, sit-to-stand transition, walking, turning) performed under varying conditions (speed, environment). An artificial neural network was used to classify good and bad sequences of joint orientation with a sensitivity and a specificity above 83%. This study confirms the possibility to perform QC on IMU joint orientation data based on raw signal features. This innovative QC approach may be of particular interest in a big data context, such as for remote-monitoring of patients’ mobility.
RECOGNIZING CALL-CENTER SPEECH USING MODELS TRAINED FROM OTHER DOMAINS

In this paper, we introduce a new conversational speech task – recognizing call -center speech – using data collected from Dragon’s own technical support line. We compare performance of models trained from conversational telephone speech (the Switchboard corpus) and models trained from predominantly read, microphone speech, and report on a series of experiments focusing on adapting the microphone speech models to the telephone channel and conversational task. We also discuss the importance of task-specific language model data. We benchmark our test set by comparing the performance of our 1998 Switchboard Evaluation system to that of our simpler call -center system.
Radio-localization in underground narrow-vein mines using neural networks with in-built tracking and time diversity

In the mining industry, knowing the position of miners and/or equipments is an important safety measure that reduces risks and improves the security of that facility. Being an indoor environment, wireless transmitted signals in underground narrow-vein mines suffer multiple kinds of distortions due to extreme multipath and non-line of sight (NLOS) conditions. One of the proposed solutions to accurate localization in such challenging environments is based on extracting the channel impulse response (CIR) of the received signal and using the fingerprinting technique combined with cooperative artificial neural networks (ANNs). Such localization systems use the spatial domain where the reference localizing units are implemented at different positions away from the transmitter. In this article, we introduce a localization technique that uses fingerprints successively recorded in time with in-built tracking as an alternative method to localize. Unlike the spatial-domain technique where cooperative localizing units collect memoryless fingerprints from different locations, this technique uses one localizing unit and is capable of estimating the position of a transmitter precisely using its current and previous registered fingerprints in time. Localization using time-domain fingerprinting (i.e., tracking) and ANNs is introduced as a new method that exploits time diversity and improves the accuracy, precision and scalability of the positioning system.
Down-Modulation of TCR Expression by Salmonella enterica serovar Typhimurium1

T cell-mediated adaptive immunity is required to help clear infection with the facultative intracellular bacterial pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium), yet development of T cell-mediated adaptive immunity to S. Typhimurium has been described as slow and inefficient. A key step in inducing T cell-mediated adaptive immunity is T cell priming; the activation, proliferation, and differentiation of naive T cells following initial encounter with Ag. We previously demonstrated that S. Typhimurium had a direct inhibitory effect on naive T cells from mouse, blocking their proliferation. In this study, we show that S. Typhimurium down-modulates expression of the TCR β-chain, a molecule that is essential for Ag recognition and T cell function. Specifically, we demonstrate that reduced amounts of surface and intracellular TCR-β protein and decreased levels of tcrβ transcript are expressed by T cells cultured in the presence of S. Typhimurium. We further show that the down-modulation of TCR-β expression requires contact between S. Typhimurium and the T cells and that once contact occurs, a factor capable of reducing TCR-β expression is secreted. These results provide new insight into the mechanism by which S. Typhimurium may inhibit T cell priming and avoid clearance by the adaptive immune system.

The review article first presents a brief overview of each chapter, focusing on the main contributions of the respective authors. This does not fully do justice to their work since these chapters include much more than can be considered here, but it will provide a useful summary of the main topics addressed idea of the various sections of the book. We then single out and discuss some of the most important implications of these new developments from the point of view of data users.
IndeGS: Index Supported Graphics Data Server for CFD Data Postprocessing

Virtual reality techniques particularly in the field of CFD (computational fluid dynamics) are of growing importance due to their ability to offer comfortable means to interactively explore 3D data sets. The growing accuracy of the simulations brings modern main memory based visualization frameworks to their limits, inducing a limitation on CFD data sizes and an increase in query response times, which are obliged to be very low for efficient interactive exploration. We therefore developed "IndeGS", the index supported graphics data server, to offer efficient dynamic view dependent query processing on secondary storage indexes organized by "IndeGS" offering a high degree of interactivity and mobility in VR environments in the context of CFD postprocessing on arbitrarily sized data sets. Our demonstration setup presents "IndeGS" as an independent network component which can be addressed by arbitrary VR visualization hardware ranging from complex setups (e.g. CAVE, HoloBench) over standard PCs to mobile devices (e.g. PDAs). Our demonstration includes a 2D visualization prototype and a comfortable user interface to simulate view dependent CFD postprocessing performed by an interactive user freely roaming a fully immersive VR environment. Hereby, the effects of the use of different distance functions and query strategies integrated into "IndeGS" are visualized in a comprehensible way.
ω-Inductive completion of monoidal categories and infinite petri net computations

There exists a KZ-doctrine on the 2-category of the locally small categories whose algebras are exactly the categories which admits all the colimits indexed by ω-chains. The paper presents a wide survey of this topic. In addition, we show that this chain cocompletion KZ-doctrine lifts smoothly to KZ-doctrines on (many variations of) the 2-categories of monoidal and symmetric monoidal categories, thus yielding a universal construction of colimits of ω-chains in those categories. Since the processes of Petri nets may be axiomatized in terms of symmetric monoidal categories this result provides a universal construction of the algebra of infinite processes of a Petri net.

IR-BASE: An integrated framework for the research and teaching of information retrieval technologies

Due to the rapid growth in digital storage technologies, Information Retrieval (IR) has gained a significant importance, both for academia and for the industry. However, very few proposals have been made for the creation of an environment capable of both providing useful IR services and acting as a workbench for the design, implementation, and research of new IR solutions. In this work, we propose IR-BASE, a basic object oriented framework for the integration of components, documentation and services, focused on the rapid development of prototypes for research and teaching. At its core, IR-BASE consists of a set of base classes that provide a skeleton to create new IR components, a set of guidelines to ensure that the developed components are fully interoperable, and a component pool, where IR-BASE users can find implementations of all kinds of functionalities needed to build a full IR system, and to which IR-BASE users can contribute with their own implementations. IR-BASE is of interest not only to IR researchers and professionals, who want to rapidly develop prototypes to test new ideas, but also to teachers and students, who will have an easily configurable, modifiable and extendible set of components to act has a basis for learning, building and experimenting with current IR algorithms.
Uyghur morpheme-based language models and ASR

Uyghur language is an agglutinative language in which words are formed by suffixes attaching to a stem (or root). Because of the explosive nature in vocabulary of the agglutinative languages, several morpheme-based language models are built and experiments are implemented. Morpheme is the smallest meaning bearing unit. In this research, morpheme is referred to any of prefix, stem, or suffix. As a result, a large vocabulary ASR system is built on the basis of Julius system. Several ASR results on language models based on different units (word, morpheme, and syllable) are compared.
The Challenges of New Software for a New Architecture

The IA-64 architecture is designed with a unique combination of rich features so that it overcomes the limitations of traditional architectures and provides performance scalability for the future. The IA-64 features expose new opportunities for the compiler to optimize applications. We have incorporated into the Intel IA-64 compiler the key technology necessary to exploit these new optimization opportunities and to boost the performance of applications on the IA-64 hardware. In this paper, we provide an overview of the Intel IA-64 compiler, discuss and illustrate several optimization techniques, and explain how these optimizations help harness the power of IA-64 for higher application performance.
ON BIFURCATIONS, VOLTAGE COLLAPSE AND LOAD MODELING

This paper discusses the relation between bifurcations and power systems stability through a thorough analysis of sev- eral examples, to clarify some ideas regarding the usefulness and limitations of bifurcation theory in network studies and operation, particularly in voltage stability related issues. Different types of load models are used in a sample system to analyze their effect on system stability and bifurcation. Finally, the Ecuadorian National Interconnected System (SNI in Spanish) is used to depict and dis- cuss the effect of load modeling in saddle-node bifurcation analysis of real power systems.
