Training-Induced Improvement of Response Selection and Error Detection in Aging Assessed by Task Switching: Effects of Cognitive, Physical, and Relaxation Training

Cognitive control functions decline with increasing age. The present study examines if different types of group-based and trainer-guided training effectively enhance performance of older adults in a task switching task, and how this expected enhancement is reflected in changes of cognitive functions, as measured in electrophysiological brain activity (event-related potentials). One hundred forty-one healthy participants aged 65 years and older were randomly assigned to one of four groups: physical training (combined aerobic and strength training), cognitive training (paper–pencil and computer-aided), relaxation and wellness (social control group), and a control group that did not receive any intervention. Training sessions took place twice a week for 90 min for a period of 4 months. The results showed a greater improvement of performance for attendants of the cognitive training group compared to the other groups. This improvement was evident in a reduction of mixing costs in accuracy and intraindividual variability of speed, indexing improved maintenance of multiple task sets in working memory, and an enhanced coherence of neuronal processing. These findings were supported by event-related brain potentials which showed higher amplitudes in a number of potentials associated with response selection (N2), allocation of cognitive resources (P3b), and error detection (Ne). Taken together, our findings suggest neurocognitive plasticity of aging brains which can be stimulated by broad and multilayered cognitive training and assessed in detail by electrophysiological methods.
A Novel Deployment Method for Communication-Intensive Applications in Service Clouds

The service platforms are migrating to clouds for reasonably solving long construction periods, low resource utilizations, and isolated constructions of service platforms. However, when the migration is conducted in service clouds, there is a little focus of deploying communication-intensive applications in previous deployment methods. To address this problem, this paper proposed the combination of the online deployment and the offline deployment for deploying communication-intensive applications in service clouds. Firstly, the system architecture was designed for implementing the communication-aware deployment method for communication-intensive applications in service clouds. Secondly, in the online-deployment algorithm and the offline-deployment algorithm, service instances were deployed in an optimal cloud node based on the communication overhead which is determined by the communication traffic between services, as well as the communication performance between cloud nodes. Finally, the experimental results demonstrated that the proposed methods deployed communication-intensive applications effectively with lower latency and lower load compared with existing algorithms.
Chemoautotrophic growth of hydrogen-uptake-positive strains of Rhizobium japonicum

Recently reported research from this laboratory has demonstrated the autotrophic growth of certain hydrogen-uptake-positive strains of Rhizobium japonicum and defined minimal conditions for such growth. Ribulose 1,5-bisphosphate carboxylase has been detected in autotrophically growing cells, but at low specific activity. Moreover, growth rates were low, and growth ceased at low cell densities. We report here improved autotrophic growth rates of R. japonicum SR through the use of a modified mineral salts/vitamins medium and a programmed increase in oxygen tension as autotrophic growth proceeds. Under these conditions, ribulose, 1,5-biphosphate carboxylase activity increased greater than 10-fold and crude-extract-uptake-hydrogenase activities were from 20 to 47 times those heretofore reported for free-living R. japonicum. It is likely that previous assays for these enzymes were done on preparations of cells in which their synthesis had been partially repressed. The contribution of CO2 fixation to organic carbon accumulation in autotrophic cells was assessed as sufficient to support observed growth. Enzymological determination of the product of carbon fixation has established a stoichiometric ratio of 1.9 mol of 3-phosphoglycerate per mol of CO2 fixed and unequivocally assigns the role of carbon fixation catalysis to ribulose 1,5-bisphosphate carboxylase. Ammonium served best as a nitrogen source, nitrate was less effective, and gaseous nitrogen would not support autotrophic growth. Ecological, evolutionary, and practical considerations of autotrophy in the rhizobia are briefly discussed in the light of our findings.
"Sit-still and Shut-up": The Construction of Childhood and Classroom Management Pedagogies in a Preservice Education Textbook

This study addresses the limitations and restrictions of approaches to classroom management that are promoted in one particular textbook that is used in Teacher Education faculties in Canada. It contributes to building an understanding of the role of textbooks in endorsing certain truth and knowledge claims about childhood and classroom management. The thesis is informed theoretically by Foucault (1977-1982), Gee (2001) and poststructuralists such as Weedon (1999). Through undertaking a discourse analysis informed by the work of Gee and Foucault, I conduct a single case study of one particular textbook to highlight the particular role of educational psychology as ‘a regime of truth’ in defining and legitimating what is to count as an effective approach to classroom management. My own autoethnographic accounts as a classroom teacher are also used and weaved throughout the analysis and serve to challenge the normative claims about classroom management made in the textbook. The implications of introducing preservice education students to only one ‘regime of truth’ concerning classroom management in terms of elaborating more socially just pedagogies are outlined. I recommend increasing access to discourse of classroom management, specifically pedagogy that position the child as ‘political agent’ with voice and potential to contribute to the management of their own education. This thesis is a part of a larger attempt to achieve equity and social justice education in which the dignities of children are respected and their voices are heard.
Approaches to knowledge reductions in inconsistent systems

This article deals with approaches to knowledge reductions in inconsistent information systems (ISs). The main objective of this work was to introduce a new kind of knowledge reduction called a maximum distribution reduct, which preserves all maximum decision classes. This type of reduction eliminates the harsh requirements of the distribution reduct and overcomes the drawback of the possible reduct that the derived decision rules may be incompatible with the ones derived from the original system. Then, the relationships among the maximum distribution reduct, the distribution reduct, and the possible reduct were discussed. The judgement theorems and discernibility matrices associated with the three reductions were examined, from which we can obtain approaches to knowledge reductions in rough set theory (RST). © 2003 Wiley Periodicals, Inc.
A ray launching approach for modeling an FMCW radar system

Virtual testing can improve safety and quality of driver assistance systems. However, for the accuracy of the whole simulation, the realism of the virtual sensors is crucial. This paper describes a method for simulating an automotive FMCW radar from the wave transmission up to the intermediate frequency signal. The wave propagation is simulated using geometrical optics and ray launching. To obtain high fidelity, antenna power patterns of transmitter and receiver, reflection, and ray divergence due to curved surfaces are included. Moreover the model inherently includes interference, limited resolution and energy conservation. In contrast to most previous work, our model is deployed in the detailed environment of a driving simulator. Finally, the implementation of the ray launcher using the GPU accelerated OptiX ray tracing engine proves real-time performance and comparable results to recorded measurements.
Human-Inspired Anticipative Postural Control Architecture for Humanoid Robots

The study of Human Postural Control (HPC) system reveals the existence of an anticipative component for improving its performance. This anticipative subsystem is able to preview future consequences caused by a postural disturbance and, as well, to trigger corrective actions. This paper presents the novel high level architecture for the humanoid robot TEO based on the same principles than the human system. The core of the architecture is an anticipative system for predicting postural corrections based on the evaluation of unexpected events or surprises. Basically, these events are caused by the mismatch between sensory perceptions and the expected. The resulting surprise is used by a decision making system that decides whether a correction is necessary, and selects the adequate graded postural correction from a set of motion patterns or synergies. All the anticipative process is enabled by Neuro-Fuzzy modules that provide the system with human style reasoning behaviour.
An Agreement Measure for Determining Inter-Annotator Reliability of Human Judgements on Affective Text

An affective text may be judged to belong to multiple affect categories as it may evoke different affects with varying degree of intensity. For affect classification of text, it is often required to annotate text corpus with affect categories. This task is often performed by a number of human judges. This paper presents a new agreement measure inspired by Kappa coefficient to compute inter-annotator reliability when the annotators have freedom to categorize a text into more than one class. The extended reliability coefficient has been applied to measure the quality of an affective text corpus. An analysis of the factors that influence corpus quality has been provided.
Water vapor, cloud liquid water content and wind speed in tropical, extratropical and polar cyclones over the Northwest Pacific Ocean

The brightness temperatures TBs measured by Aqua AMSR-E and Meteor-M N 1 MTVZA-GY microwave radiometers as well as the total atmospheric water vapor content, total cloud liquid water content and sea surface wind speed retrieved from the TBs are used to study the structure and evolution of severe marine weather systems and to improve temporal resolution required for their satellite monitoring. The microwave data are compared with visible and infrared images and with in situ observations. The microwave signatures of tropical and polar hurricanes are compared to get more accurate data on the emissivity of the surface at gale winds.
Learning object models from semistructured Web documents

This paper presents an automated approach to learning object models by means of useful object data extracted from data-intensive semistructured Web documents such as product descriptions. Modeling intensive data on the Web involves the following three phrases: first, we identify the object region covering the descriptions of object data when irrelevant contents from the Web documents are excluded. Second, we partition the contents of different object data appearing in the object region and construct object data using hierarchical XML outputs. Third, we induce the abstract object model from the analogous object data. This model would match the corresponding object data from a Web site more precisely and comprehensively than the existing handcrafted ontologies. The main contribution of this study is in developing a fully automated approach to extract object data and object model from semistructured Web documents using kernel-based matching and view syntax interpretation. Our system, OnModer, can automatically construct object data and induce object models from complicated Web documents, such as the technical descriptions of personal computers and digital cameras downloaded from manufacturers' and vendors' sites. A comparison with the available hand-crafted ontologies and tests on an open corpus demonstrate that our framework is effective in extracting meaningful and comprehensive models.
Sharpness for texture retrieval in multiscale domain

Sharpness is an important geometrical feature of 2D images which can be measured by statistic methods. FISH and FISHbb are very efficient measurements of sharpness for a whole image. In this paper, we adopt and slightly modify FISH and FISHbb as kinds of texture features, combined with traditional statistical features such as means and standard deviations, and apply these features for texture retrieval in multiscale domain. We evaluate these combined features in several different multiscale transforms such as discrete Wavelet transform, dual-tree complex Wavelet transform, Contourlet transform and pyramidal dual-tree directional filter banks. The texture retrieval scheme involving sharpness and multiscale achieves good performance with higher retrieval accuracy in numerical experiments, and these results show that sharpness is a kind of efficient texture feature for 2D images.
Optimal two-dimension common centroid layout generation for MOS transistors unit-circuit

A general algorithm for fitting arbitrary channel width transistors in a two-dimensional common centroid MOS transistor matrix is presented. The proposed algorithm guarantees the layout of the transistor unit-circuit not only to be complete common centroid, but also optimal in all the common centroid structures. A novel channel routing algorithm to implement common centroid routing is also proposed. Feasibility of the algorithm is demonstrated by practical analog transistor unit-circuits.
Complete bicornuate uterus with complete transverse vaginal septum

Bicornuate uterus has two symmetric uterine cavities that are fused caudally and have some degree of communication between two cavities, usually at the uterine isthmus. A complete bicornuate uterus has a seperatory cleft of tissue that is extended to the internal OS. Lesser degree of septation of the two uterine horns has constitution, a partial bicornuate uterus. Bicornuate uterus is a class of four anomaly of American fertility society classification of mullerian anomalies. Here we report a case of a 19-year-old female patient with complaint of abdominal pain and spotting since 4 months ago. In sonography it revealed bicornuate uterus and hematocolpos. The patient underwent general anesthesia and examination that reveal the transverse vaginal septum. Septum removed by resectoscope was successful.
Detection and Differentiation of vanC-1,vanC-2, and vanC-3 Glycopeptide Resistance Genes in Enterococci

ABSTRACT The VanC phenotype, as found in Enterococcus gallinarum, E. casseliflavus, and E. flavescens, is characterized by intrinsic low-level resistance to vancomycin. The nucleotide sequences of the vanC-1 gene inE. gallinarum, the vanC-2 gene inE. casseliflavus, and the vanC-3 gene inE. flavescens have been reported, although there is some disagreement as to whether E. flavescens is a legitimate enterococcal species. Previous attempts to differentiate the vanC-2 and vanC-3 genes by PCR analysis have been unsuccessful. The purpose of the present study was to detect and differentiate the three vanC determinants and examine the distribution of these genes in a collection of both typical and atypical enterococci. The 796-bp vanC-1 PCR product was amplified only from E. gallinarumisolates. As expected, due to the extensive homology in thevanC-2 and vanC-3 gene sequences, all of the E. casseliflavus and E. casseliflavus/flavescens isolates produced the 484-bpvanC-2 PCR product, although the E. gallinarum isolates were negative. Only the E. casseliflavus/flavescens isolates produced the 224-bpvanC-3 product. Using the three sets of primers, we were able to detect and distinguish the vanC-1,vanC-2, and vanC-3 genes from both typical and atypical enterococci strains. Antimicrobial susceptibility tests and analysis of genomic DNA by pulsed-field gel electrophoresis were also performed, but the results indicated that they were not able to distinguish among strains possessing the three vanCgenotypes.
Rehabilitasi Kardiovaskular Di Indonesia

“A process by which a person is restored to an optimal physical, medical, psychological, social, emotional, sexual, vocational and economic status. ” Itulah definisi Cardiac Rehabilitation dari WHO tahun 19691 , yang kemudian ‘disempurnakan’ pada saat ini dengan memperhatikan dasar penyakit, proses dan kondisi pasca sakit . Definisi tersebut dijabarkan dalam definisi terkini yaitu: “The rehabilitation of cardiac patients is the sum of activities required to influence favourably the underlying cause of the disease, as well as the best possible physical, mental and social conditions, so that they may by their own efforts, preserve or resume when lost, as normal a place as possible in the society”. 2
Performance Analysis of Adaptive Beamforming Algorithms for Orthogonal Frequency Division Multiplexing System

Orthogonal Frequency Division Multiplexing (OFDM) is gaining popularity for high data rate communication systems. We propose the use of adaptive beamforming for interference rejection in OFDM systems, due to its advantages over equalization. An adaptive beamformer uses the concept of spatial filtering to direct the antenna beam towards the desired signal/transmitter and place a null towards the interfering signal. The Fast Fourier Transform (FFT) at the receiver end of an OFDM system enables the use of frequency domain beamforming to reduce narrow band interference individually across all the subcarriers. We implemented both decision directed and blind algorithms. Use of these algorithms reduced the Bit Error Rate (BER) to a great extent. The performance analysis for Least Mean Square (LMS) algorithm, Recursive Least Squares (RLS) and Constant Modulus Algorithm (CMA) for hundred OFDM symbols and five hundred and twelve subcarriers, four hundred and is provided.
Output Hazard-Free Transition Delay Fault Test Generation

Scan based timing comparison tests offer a potential solution to the problem of small delay detection in aggressive nanometer technologies. However, such tests require that circuit delays be unambiguously captured in the scan chains using multiple fast clocks. To ensure this, only those signals that are known to be hazard free at capture are analysed for timing information from the scan-out data. In this paper we present the first systematic ATPG driven approach for generating high coverage output hazard free TDF tests for scan delay testing. Results indicate that acceptable coverage can be achieved, no worse than about 10% below the unconstrained TDF coverage for both LOS and LOC tests, even in the presence of significant process variations.
Using Craigslist Messages for Syphilis Surveillance

A 2010 study by the Centers for Disease Control (CDC) shows a 39% increase in syphilis cases from 2006-20091.The majority of this increase is amongst the MSM community, specifically young black men. The anonymity and relative ease of finding partners on the Internet has facilitated a culture of casual sexual encounters encompassing a variety of unsafe sexual practices, e.g., anonymous partners, illegal drug use, unprotected sex, group sex, etc. These anonymous sexual encounters make it more difficult for public health officials to notify exposed partners.
Type inference and subtyping for higher-order generative communication

Models for generative communication use a common space, where concurrent agents put or retrieve data; data extraction is controlled by various kinds of filtering techniques, usually based on the structure of the data itself. However, for higher-order communication, i.e. when the data consists of software fragments, such techniques are not appropriate: structural information does not reflect the behaviour of a software fragment. This paper studies a filtering mechanism based instead on type information, so that software components can be retrieved according to type specifications. A rich type system with polymorphism and subtyping gives enough flexibility to formulate type specifications at various levels of detail.
Rapid 3D Phenotyping of Cardiovascular Development in Mouse Embryos by Micro-CT With Iodine Staining

Background—Microcomputed tomography (micro-CT) has been used extensively in research to generate high-resolution 3D images of calcified tissues in small animals nondestructively. It has been especially useful for the characterization of skeletal mutations but limited in its utility for the analysis of soft tissue such as the cardiovascular system. Visualization of the cardiovascular system has been largely restricted to structures that can be filled with radiopaque intravascular contrast agents in adult animals. Recent ex vivo studies using osmium tetroxide, iodinated contrast agents, inorganic iodine, and phosphotungstic acid have demonstrated the ability to stain soft tissues differentially, allowing for high intertissue contrast in micro-CT images. In the present study, we demonstrate the application of this technology for visualization of cardiovascular structures in developing mouse embryos using Lugol solution (aqueous potassium iodide plus iodine). Methods and Results—We show the optimization of this method to obtain ex vivo micro-CT images of embryonic and neonatal mice with excellent soft-tissue contrast. We demonstrate the utility of this method to visualize key structures during cardiovascular development at various stages of embryogenesis. Our method benefits from the ease of sample preparation, low toxicity, and low cost. Furthermore, we show how multiple cardiac defects can be demonstrated by micro-CT in a single specimen with a known genetic lesion. Indeed, a previously undescribed cardiac venous abnormality is revealed in a PlexinD1 mutant mouse. Conclusions—Micro-CT of iodine-stained tissue is a valuable technique for the characterization of cardiovascular development and defects in mouse models of congenital heart disease.
Cluster Analysis of Spatial Patterns in Malaysian Tree Species

Tree species in tropical rain forests exhibit a rich panoply of spatial patterns that beg ecological explanation. The analysis of tropical census data typically relies on spatial statistics, which quantify the average aggregation tendency of a species. In this article we develop a cluster‐based approach that complements traditional spatial statistics in the exploration and analysis of ecological hypotheses for spatial pattern. We apply this technique to six study species within a fully mapped 50‐ha forest census in peninsular Malaysia. For each species we identify the scale(s) of spatial aggregation and the corresponding tree clusters. We study the correlation between cluster locations and abiotic variables such as topography. We find that the distribution of cluster sizes exhibits equilibrium and nonequilibrium behavior depending on species life history. The distribution of tree diameters within clusters also varies according to species life history. At different spatial scales, we find evidence for both niche‐based and dispersal‐limited processes producing spatial pattern. Our methodology for identifying scales of aggregation and clusters is general; we discuss the method’s applicability to spatial problems outside of tropical plant ecology.
