Indications for 3 Mpc-scale large-scale structure associated with an X-ray luminous cluster of galaxies at z=0.95 ?

Context. X-ray luminous clusters of galaxies at z ∼ 1 are emerging as major cosmological probes and are fundamental tools to study the cosmic large-scale structure and environmental effects of galaxy evolution at large look-back times. Aims. We present details of the newly-discovered galaxy cluster XMMU J0104.4-0630 at z = 0.947 and a probable associated system in the LSS environment. Methods. The clusters were found in a systematic study for high-redshift systems using deep archival XMM-Newton data for the serendipitous detection and the X-ray analysis, complemented by optical/near-infrared (NIR) imaging observations and spectroscopy of the main cluster. Results. We find a well-evolved, intermediate luminosity cluster with L 0.5−2. 0k eV X = (6.4 ± 1.3) × 10 43 h −2 70 erg s −1 and strong central 1.4 GHz radio emission. The cluster galaxy population exhibits a pronounced transition toward bluer colors at cluster-centric distances of 1−2 core radii, consistent with an age difference of 1−2 Gyr for a single burst solar metallicity model. The second, less evolved X-ray cluster at a projected distance of 6.4 � (∼3 Mpc) and a concordant red-sequence color likely forms a cluster-cluster bridge with the main target as part of its surrounding large-scale structure at z � 0.95.
THE VISUAL CORTEX, ITS LOCALIZATION, HISTOLOGICAL STRUCTURE, AND PHYSIOLOGICAL FUNCTION

In the study of the human cortex it seems well to follow the same primary divisions for the entire cortex, while in certain areas some layers may assume certain modifications; viz., in the area striata it seems clearer to retain the sixth layer ground type, of which the fourth is subdivided into three secondary layers. The visual cortex, on account of its relation to the act of seeing, is an especially interesting field for study. About the calcarine fissure one can readily see with the naked eye a stripe of white fibers lying in the gray substance, called stria of Gennari or of Vicq-d' Azyr. This layer is considered by Brodmann in the second subdivision of the fourth primary layer. The two most characteristic types of the cortex are the giant pyramid type, called area gigantopyramidalis, and the calcarine type, called area striata. The higher types of mammals afford excellent material for comparison. Minkowski's experimental study of the dog indicates that the clinical, anatomical visual sphere is covered with the cytoarchitectonic sphere; for lasting visual trouble can be caused only by extirpation of the area striata. The subcortical visual center in mammals undergoes secondary degeneration through destruction of the area striata, and therefore depends on the cortex. Also certain parts of the corpus geniculatum externum have an exact projection over certain areas of the cortex.
The Role of Positive Affect in Enhancing Extinction Learning and Exposure Therapy for Anxiety Disorders

Although exposure is a valid treatment for anxiety disorders, efforts are being made to improve its overall effectiveness. The present article discusses one potential method of optimizing extinction learning and exposure therapy: increasing positive affect. The effect of positive affect on learning is discussed in regards to various components of learning, including attention, encoding, rehearsal, consolidation, retrieval, and stimulus valence. These effects are then discussed specifically with extinction learning and exposure therapy. The authors conclude that increasing positive affect during exposures may enhance exposure therapy via various these learning mechanisms but that this awaits further testing.
Congestion control meets medium access: throughput, delay, and complexity

This paper looks at the problem of designing medium access algorithm for wireless networks with the objective of providing high throughput and low delay performance to the users, while requiring only a modest computational effort at the transmitters and receivers. Additive inter-user interference at the receivers is an important physical layer characteristic of wireless networks. Today's Wi-Fi networks are based upon the abstraction of physical layer where inter-user interference is considered as noise leading to the 'collision' model in which users are required to co-ordinate their transmissions through Carrier Sensing Multiple Access (CSMA)-based schemes to avoid interference. This, in turn, leads to an inherent performance trade-off [1]: it is impossible to obtain high throughput and low delay by means of low complexity medium access algorithm (unless P=NP). As the main result, we establish that this trade-off is primarily due to treating interference as noise in the current wireless architecture. Concretely, we develop a simple medium access algorithm that allows for simultaneous transmissions of users to the same receiver by performing joint decoding at receivers, over time. For a receiver to be able to decode multiple transmissions quickly enough, we develop appropriate congestion control where each transmitter maintains a "window" of undecoded transmitted data that is adjusted based upon the "feedback" from the receiver. In summary, this provides an efficient, low complexity "online" code operating at varying rate, and the system as a whole experiences only small amount of delay (including decoding time) while operating at high throughput.
A new approach to compress RFID data for the construction of the RFID data warehouse

Radio Frequency Identification (RFID) applications set to play an essential role in object tracking and supply chain management systems. In future RFID technologies are expected that every major retailer will use RFID systems to track the movement of products from suppliers to warehouses, transportation and distribution. The volume of information generated by such systems is enormous. Despite all these, RFID technology presents numerous challenges, including incomplete data, lack of location and containment information and very high volumes. In this paper we propose a novel data interpretation and compression substrate over RFID streams to address these challenges in enterprise supply chain environments. Our results demonostrate that our inference techniques provide good accuracy while retaining efficiency, and our compression algorithm yields significant reduction in data volume.
Estimation and Model Selection Based Inference in Single and Multiple Threshold Models

This paper evaluates the properties of a joint and sequential estimation procedure for estimating the parameters of single and multiple threshold models. We initially proceed under the assumption that the number of regimes is known a priori but subsequently relax this assumption via the introduction of a model selection based procedure that allows the estimation of both the unknown parameters and their number to be performed jointly. Theoretical properties of the resulting estimators are derived and their finite sample properties investigated.
Simulation study of the electrophysiological mechanisms for heart failure phenotype

Prolongation of action potential duration (APD) and altered calcium (Ca<sup>2+</sup>) handling in ventricular myocytes are commonly observed in heart failure (HF). This study describes a mathematical model of human HF, using a modified version of the Grandi et al. formulation for human ventricular action potential, which includes the late Na<sup>+</sup> current (I<inf>NaL</inf>). A sensitivity analysis is performed to investigate how the reported variability in HF remodeling might modulate the main electrophysiological (EP) characteristics in HF. Our simulations reproduced experimental observations in failing myocytes and the APD<inf>90</inf> was increased in 24% in HF versus normal ones, diastolic [Ca<sup>2+</sup>]<inf>i</inf> was slightly increased, whereas peak systolic [Ca<sup>2+</sup>]<inf>i</inf> was reduced to 41% of its normal value. From the sensitivity analysis it could be extracted that APD is particularly sensitive to I<inf>NaL</inf> and I<inf>NaK</inf>. The most impactful parameters on Ca<sup>2+</sup> handling are the SERCA function, I<inf>NaL</inf>, I<inf>NaK</inf>, I<inf>leak</inf>, I<inf>Ca, b</inf> and I<inf>NCX</inf>.
Pulmonary Tuberculosis and Mycobacterium Tuberculosis: Modern Molecular Epidemiology and Perspectives

remains directly related to the social and hygiene conditions of human populations. TB remains a major public health problem worldwide and the first cause of mortality attributable to a single infectious agent, especially in developing countries where the consequences of this disease remain more serious and the infection risks are higher [54,148] (see Fig. 1.1). According to the World Health Organization (WHO, www.who.int), the estimated number of cases of TB worldwide in 2003 was 8.8 million, 3.9 million of which were sputum positive, and deaths from TB (including TB deaths in people infected with HIV) were 1,747,000. Furthermore, it is estimated that there are currently 2.1 billion people worldwide who are latently infected with the tubercle bacillus and could develop the active form of the disease in the case of reactivation. The recrudescence of this disease in several countries, the emergence of multidrug-resistant strains and the association of TB with the HIV pandemic show the need to improve research on this pathogen in applied and basic research in order to better understand the transmission of TB and to eradicate this disease.The objective of this chapter is to give an overview of the biology, genetics, and pathogeny of M. tuberculosis (MTB), to describe the current molecular methodologies available for identifying the MTB populations responsible for the spread of TB and the outbreaks, and to show the contribution of genetic epidemiology studies in understanding global and local epidemiology of TB.
Speech Synthesis Data Collection for Visually Impaired Person

Crowdsourcing platforms provide attractive solutions for collecting speech synthesis data for visually impaired person. However, quality control problems remain because of low-quality volunteer workers. In this paper, we propose the design of a crowdsourcing system that allows us to devise quality control methods. We introduce four worker selection methods; preprocessing filtering, real-time filtering, post-processing filtering, and guess-processing filtering. These methods include a novel approach that utilizes a collaborative filtering technique in addition to a basic approach involving initial training or use of gold-standard data. These quality control methods improved the quality of collected speech synthesis data. Moreover, we have already collected 140,000 Japanese words from 500 million web data for speech synthesis data.
Rare Titin (TTN) Variants in Diseases Associated with Sudden Cardiac Death

A leading cause of death in western countries is sudden cardiac death, and can be associated with genetic disease. Next-generation sequencing has allowed thorough analysis of genes associated with this entity, including, most recently, titin. We aimed to identify potentially pathogenic genetic variants in titin. A total of 1126 samples were analyzed using a custom sequencing panel including major genes related to sudden cardiac death. Our cohort was divided into three groups: 432 cases from patients with cardiomyopathies, 130 cases from patients with channelopathies, and 564 post-mortem samples from individuals showing anatomical healthy hearts and non-conclusive causes of death after comprehensive autopsy. None of the patients included had definite pathogenic variants in the genes analyzed by our custom cardio-panel. Retrospective analysis comparing the in-house database and available public databases also was performed. We identified 554 rare variants in titin, 282 of which were novel. Seven were previously reported as pathogenic. Of these 554 variants, 493 were missense variants, 233 of which were novel. Of all variants identified, 399 were unique and 155 were identified at least twice. No definite pathogenic variants were identified in any of genes analyzed. We identified rare, mostly novel, titin variants that seem to play a potentially pathogenic role in sudden cardiac death. Additional studies should be performed to clarify the role of these variants in sudden cardiac death.
Aberrant DNA Methylation and Prostate Cancer

Prostate cancer (PCa) is the most prevalent cancer, a significant contributor to morbidity and a leading cause of cancer-related death in men in Western industrialized countries. In contrast to genetic changes that vary among individual cases, somatic epigenetic alterations are early and highly consistent events. Epigenetics encompasses several different phenomena, such as DNA methylation, histone modifications, RNA interference, and genomic imprinting. Epigenetic processes regulate gene expression and can change malignancy-associated phenotypes such as growth, migration, invasion, or angiogenesis. Methylations of certain genes are associated with PCa progression. Compared to normal prostate tissues, several hypermethylated genes have also been identified in benign prostate hyperplasia, which suggests a role for aberrant methylation in this growth dysfunction. Global and gene-specific DNA methylation could be affected by environmental and dietary factors. Among other epigenetic changes, aberrant DNA methylation might have a great potential as diagnostic or prognostic marker for PCa and could be tested in tumor tissues and various body fluids (e.g., serum, urine). The DNA methylation markers are simple in nature, have high sensitivity, and could be detected either quantitatively or qualitatively. Availability of genome-wide screening methodologies also allows the identification of epigenetic signatures in high throughput population studies. Unlike irreversible genetic changes, epigenetic alterations are reversible and could be used for PCa targeted therapies.
Daniel Robert Active auditory mechanics in mosquitoes

Comparable active auditory mechanics is now demonstrated in insects. In mosquitoes, Johnston's organ transduces sound-induced vibrations of the antennal £agellum. A non-muscular`motor' activity enhances the sensitivity and tuning of the £agellar mechanical response in physiologically intact animals. This motor is capable of driving the £agellum autonomously, amplifying sound-induced vibrations at speci¢c frequencies and intensities. Motor-related electrical activity of Johnston's organ strongly suggests that mosquito hearing is improved by mechanoreceptor motility.
Designing a trace format for heap allocation events

Dynamic storage allocation continues to play an important role in the performance and correctness of systems ranging from user productivity software to high-performance servers. While algorithms for dynamic storage allocation have been studied for decades, much of the literature is based on measuring the performance of benchmark programs unrepresentative of many important allocation-intensive workloads. Furthermore, to date no standard has emerged or been proposed for publishing and exchanging representative allocation workloads. In this paper, we describe a preliminary design of a trace format for such workloads and investigate its effectiveness at representing large allocation traces. Our proposal allows for a flexible encoding of information in the trace to achieve greater compression. We evaluate our preliminary design in two dimensions. First, we measure how effective these encodings are at reducing trace size. Second we consider how a meta-level specification language could be used to describe such formats and to generate trace readers and writers automatically.
Research on the selection of kernel function in SVM based facial expression recognition

Support vector machine(SVM) means that structural risk minimization principle is used to substitute Empirical risk minimization principle. SVM has shown the excellent performance in pattern recognition. The kernel function is the core of SVM, with which SVM can help to resolve many kinds of non-linear classification problems. Different kernel models and parameters have different result in the performance of the facial expression recognition system. The authors analyze the capability of polynomial kernel function and RBF kernel function in the facial expression recognition using the JAFFE expressions library. The work is valuable in the choise of kernel and its parameters in practice.
Illicit Drug Use and Crime in the United States

A silicon thin film member according to the present invention comprises a supporting substrate and an a-Si thin film formed by plasma CVD and including hydrogen. The a-Si thin film has a distribution of hydrogen density in which a hydrogen content of the a-Si thin film has a maximum value of 1x1022 atoms/cm3 or more in a position 20 nm or less away from an interface between the a-Si thin film and the supporting substrate, and the maximum value of the hydrogen content is larger than a hydrogen content of the supporting substrate on the interface. The hydrogen content of the a-Si thin film decreases from the position toward the interface and decreases from the position in a direction from the supporting substrate to the a-Si thin film.
Birth Weight, Birth Length, and Gestational Age as Indicators of Favorable Fetal Growth Conditions in a US Sample

The “fetal origins” hypothesis suggests that fetal conditions not only affect birth characteristics such as birth weight and gestational age, but also have lifelong health implications. Despite widespread interest in this hypothesis, few methodological advances have been proposed to improve the measurement and modeling of fetal conditions. A Statistics in Medicine paper by Bollen, Noble, and Adair examined favorable fetal growth conditions (FFGC) as a latent variable. Their study of Filipino children from Cebu provided evidence consistent with treating FFGC as a latent variable that largely mediates the effects of mother’s characteristics on birth weight, birth length, and gestational age. This innovative method may have widespread utility, but only if the model applies equally well across diverse settings. Our study assesses whether the FFGC model of Cebu replicates and generalizes to a very different population of children from North Carolina (N = 705) and Pennsylvania (N = 494). Using a series of structural equation models, we find that key features of the Cebu analysis replicate and generalize while we also highlight differences between these studies. Our results support treating fetal conditions as a latent variable when researchers test the fetal origins hypothesis. In addition to contributing to the substantive literature on measuring fetal conditions, we also discuss the meaning and challenges involved in replicating prior research.
An 80-MHz, 80-mW, 8-b CMOS folding A/D converter with distributed track-and-hold preprocessing

An analog-to-digital converter incorporating a distributed track-and-hold preprocessing combined with folding and interpolation techniques has been designed in CMOS technology. The presented extension of the well known folding concept has resulted in a 75 MHz maximum full-scale input signal frequency. A signal-to-noise ratio of 44 dB is obtained for this frequency. The 8-b A/D converter achieves a clock frequency of 80 MHz with a power dissipation of 80 mW from a 3.3 V supply voltage. The active chip area is 0.3 mm/sup 2/ in 0.5-/spl mu/m standard digital CMOS technology.
Understanding participation in the use of tangible tools

Although the potential for exploiting the tangibility of systems is receiving increasing and welcome attention from designers, understanding the social consequences of making systems more tangible remains an under explored domain of study (but see [3] for a valuable discussion). The focus of our recent work concerns the design and deployment of shareable, tangible devices for collaborative projects. The design and use of these devices are of research interest precisely for the ways in which physical, shareable technologies facilitate social interaction. Specifically, we have developed three tangible interfaces for collaborative learning in and outside the classroom. Ely [1], an interactive play system for young children; Moving Pictures [5], a collaborative interface for video creation; and Soundbites, a concept for supporting language learning based on the creation of sound clips (Fig. 1). We have analyzed the use of these prototypes with the specific intent to discern how the physical and systemic design features of the prototypes had consequences for the social interaction occurring around them. In this way, we are in the process of assembling a rudimentary taxonomy of ‘social consequences’ of the shareable systems. Thus far, our observations concern the ways in which (a) the emergent social structures (including the various roles that users of the technology adopt in interaction) are supported by the device, (b) the device provides for the public availability, performance, and feedback of interaction and (c) a balance is struck between the freedom and constraints in interaction.
Fuzzy Map Matching for the Atlas SLAM of Mobile Robots

A novel approach of reducing computation complexity for simultaneous localization and mapping (SLAM) of mobile robots, which based on self-organizing fuzzy neural networks (SONN) was proposed in this paper. The matching component for local maps in the atlas SLAM system is replaced by an SONN. Our approach is superior to the original one by taking all of the feature parameters in a local map instead of a set of map signature elements. In addition, the computation cost which is required to determine the active local map and to close loop was reduced to a reasonable size.

An Unfitted Discontinuous Galerkin Method Applied to Elliptic Interface Problems

In this article an unfitted discontinuous Galerkin method is proposed to discretize elliptic interface problems. The method is based on the symmetric interior penalty discontinuous Galerkin method and can also be interpreted as a generalization of the method given by A. Hansbo and P. Hansbo [Comput. Methods Appl. Mech. Engrg. , 191 (2002), pp. 5537--5552]. We prove the optimal $h$-convergence of the method for arbitrary $p$ in the energy- and in the $L_2$-norm. In fact we present an $hp$-error estimate. We introduce a variant of the method, for which the same $hp$-convergence rates can be proved in the energy norm and which aims at controlling pointwise errors near the interface. The analysis includes grids with hanging nodes, and the proposed method is symmetric and inherits the attractive locality property of general discontinuous Galerkin methods. Numerical experiments are included.
