An task scheduling algorithm of real-time leakage power and temperature optimization for MPSoC

As technology scaling into the nanometer regime, the performance is accompanied by the ever-increasing chip power consumption, in which leakage power consumption has become a major factor. Based on temperature-electric coupling effect, we study the temperature-cooling and energy-saving algorithm for high-end multi-processor system-on-chip (MPSoC). This work proposes a TALO (Temperature-Aware Leakage Optimization) algorithm to schedule tasks for MPSoCs. TALO assigns high priority to the coolest processor when there are multi-processor can be used, reducing the temperature-electric coupling leakage power. Comparing with TALK and traditional DVS algorithm, experiments show TALO is more efficient in power consumption. It can reduce the leakage power up to 70 percents for MPSoCs in contrast with DVS algorithm. At the same time, TALO can help decrease the highest temperature of each processor in MPSoC. It can make the temperature of each processor 34°C lower than DVS systems.
A family of pseudo-Anosov braids with small dilatation

1mCn : Matsuoka’s example [22] appears as 1;1 , and Ko, Los and Song’s example [18] as 2;1 . For any m;n 1, m;n is pseudo-Anosov (Theorem 3.9). The dilatations of m;m coincide with those found by Brinkmann [7] (see also Section 4.2), who also shows that the dilatations arising in this family can be made arbitrarily close to 1. It turns out that one may find smaller dilatations by passing a strand of m;n once around the remaining strands. As a particular example, we consider the braids m;n defined by taking the rightmost-strand of m;n and passing it counter-clockwise once around the remaining strands. Figure 1 gives an illustration of m;n and m;n . The braid 1;3 is conjugate to Ham and Song’s braid 1 2 3 4 1 2 . Forjm nj 1, we show that m;n is periodic or reducible. Otherwise m;n is pseudo-Anosov with
Multi-Timescale, Gradient Descent, Temporal Difference Learning with Linear Options

Deliberating on large or continuous state spaces have been long standing challenges in reinforcement learning. Temporal Abstraction have somewhat made this possible, but efficiently planing using temporal abstraction still remains an issue. Moreover using spatial abstractions to learn policies for various situations at once while using temporal abstraction models is an open problem. We propose here an efficient algorithm which is convergent under linear function approximation while planning using temporally abstract actions. We show how this algorithm can be used along with randomly generated option models over multiple time scales to plan agents which need to act real time. Using these randomly generated option models over multiple time scales are shown to reduce number of decision epochs required to solve the given task, hence effectively reducing the time needed for deliberation.
Myeloid Cell Function in MRP-14 (S100A9) Null Mice

ABSTRACT Myeloid-related protein 14 (MRP-14) and its heterodimeric partner, MRP-8, are cytosolic calcium-binding proteins, highly expressed in neutrophils and monocytes. To understand the function of MRP-14, we performed targeted disruption of the MRP-14 gene in mice. MRP-14−/− mice showed no obvious phenotype and were fertile. MRP-8 mRNA but not protein is present in the myeloid cells of these mice, suggesting that the stability of MRP-8 protein is dependent on MRP-14 expression. A compensatory increase in other proteins was not detected in cells lacking MRP-8 and MRP-14. Although the morphology of MRP-14−/− myeloid cells was not altered, they were significantly less dense. When Ca2+ responses were investigated, there was no change in the maximal response to the chemokine MIP-2. At lower concentrations, however, there was reduced responsiveness in MRP-14−/− compared with MRP-14+/+ neutrophils. This alteration in the ability to flux Ca2+ did not impair the ability of the MRP-14−/− neutrophils to respond chemotactically to MIP-2. In addition, the myeloid cell functions of phagocytosis, superoxide burst, and apoptosis were unaffected in MRP-14−/− cells. In an in vivo model of peritonitis, MRP-14−/− mice showed no difference from wild-type mice in induced inflammatory response. The data indicate that MRP-14 and MRP-8 are dispensable for many myeloid cell functions.
Arterial spin labeling perfusion fMRI with very low task frequency

Functional magnetic resonance imaging (fMRI) has become the most widely used modality for visualizing regional brain activation in response to sensorimotor or cognitive tasks. While the majority of fMRI studies have used blood oxygenation level‐dependent (BOLD) contrast as a marker for neural activation, baseline drift effects result in poor sensitivity for detecting slow variations in neural activity. By contrast, drift effects are minimized in arterial spin labeling (ASL) perfusion contrast, primarily as a result of successive pairwise subtraction between images acquired with and without labeling. Recent data suggest that ASL contrast shows stable noise characteristics over the entire frequency spectrum, which makes it suitable for studying low‐frequency events in brain function. The present study investigates the relative sensitivities of ASL and BOLD contrast in detecting changes in motor cortex activation over a spectrum of frequencies of experimental design, where the alternating period between the resting state and activation is varied from 30 s up to 24 hr. The results demonstrate that 1) ASL contrast can detect differences in motor cortex activation over periods of minutes, hours, and even days; 2) the functional sensitivity of ASL contrast becomes superior to that of BOLD contrast when the alternating period between the resting state and activation is greater than a few minutes; and 3) task activation measured by ASL tends to have less intersubject variability than BOLD contrast. The improved sensitivity of the ASL contrast for low task frequency and longitudinal studies, along with its superior power in group analysis, is expected to extend the range of experimental designs that can be studied using fMRI.

Protection from Intracellular Oxidative Stress by Cytoglobin in Normal and Cancerous Oesophageal Cells

Cytoglobin is an intracellular globin of unknown function that is expressed mostly in cells of a myofibroblast lineage. Possible functions of cytoglobin include buffering of intracellular oxygen and detoxification of reactive oxygen species. Previous work in our laboratory has demonstrated that cytoglobin affords protection from oxidant-induced DNA damage when over expressed in vitro, but the importance of this in more physiologically relevant models of disease is unknown. Cytoglobin is a candidate for the tylosis with oesophageal cancer gene, and its expression is strongly down-regulated in non-cancerous oesophageal biopsies from patients with TOC compared with normal biopsies. Therefore, oesophageal cells provide an ideal experimental model to test our hypothesis that downregulation of cytoglobin expression sensitises cells to the damaging effects of reactive oxygen species, particularly oxidative DNA damage, and that this could potentially contribute to the TOC phenotype. In the current study, we tested this hypothesis by manipulating cytoglobin expression in both normal and oesophageal cancer cell lines, which have normal physiological and no expression of cytoglobin respectively. Our results show that, in agreement with previous findings, over expression of cytoglobin in cancer cell lines afforded protection from chemically-induced oxidative stress but this was only observed at non-physiological concentrations of cytoglobin. In addition, down regulation of cytoglobin in normal oesophageal cells had no effect on their sensitivity to oxidative stress as assessed by a number of end points. We therefore conclude that normal physiological concentrations of cytoglobin do not offer cytoprotection from reactive oxygen species, at least in the current experimental model.
Indexing and Retrieval for Genomic Databases

Genomic sequence databases are widely used by molecular biologists for homology searching. Amino acid and nucleotide databases are increasing in size exponentially, and mean sequence lengths are also increasing. In searching such databases, it is desirable to use heuristics to perform computationally intensive local alignments on selected sequences and to reduce the costs of the alignments that are attempted. We present an index-based approach for both selecting sequences that display broad similarity to a query and for fast local alignment. We show experimentally that the indexed approach results in significant savings in computationally intensive local alignments and that index-based searching is as accurate as existing exhaustive search schemes.
Attitudinal Valence and Semantic Differential Potency Scales

185 Ss rated two issues on 16 semantic differential potency scales. Ss were classified for or against the issues on the basis of their responses to two unmarked 9-cm lines descriptively labeled at the end points. Semantic differential data from the four resulting classes were factor analyzed using principal components solutions with varimax rotations. Previous research (Jones, 1969) suggested that these scales might fractionate into several components of variance and that the structure would vary depending on attitudinal valence (for-against the issue). Descriptive comparisons and comparisons employing Tucker's coefficient of congruence (Harman, 1967) supported the hypothesis of dissimilar fractionation.
Do Too Many Rights Make a Wrong? A Qualitative Study of the Experiences of a Sample of Malaysian and Singapore Private Higher Education Providers in Transnational Quality Assurance

Abstract Assuring the quality of transnational education has been an endeavour of increasing importance in the internationalisation of higher education but is also increasingly challenging given the involvement of many stakeholders. This paper focuses on the experiences of and challenges faced by private tertiary education providers in Malaysia and Singapore, which are major importers of Australian degrees, in coping with the varied and increasingly demanding requirements of different quality assurance goals, emphases and systems. Interviews with staff from private providers of tertiary education in both countries revealed that the existence of a large number of different requirements based on varied standards leads to counter‐productive and ineffective outcomes such as the diversion of resources. The experiences of Malaysia and Singapore provide valuable lessons for emerging economies, including China and India, both of which will likely be major educational providers in the coming decades.
Neural correlates of stereoscopic depth perception: A fNIRS study

The aim of the present study was to explore the brain region correlated with stereoscopic depth perception with different degree of binocular disparities. fNIRS was used to measure the neural activity of the occipital cortex induced by random-dot stereogram (RDS) with disparities from 0.1° to 1.5° and analyzed the strength and activation pattern from participants with left and right eyedness. Results revealed that the visual cortex was spatial correlated with the binocular disparity and there was a left lateralization effect for right-eye-dominant participants. Furthermore, binocular disparity around 0.5° led the strongest activation, whereas binocular disparity exceed 1.1° led lower activation which could be caused by visual fatigue. The present study supported the feasibility of fNIRS to assess the neural correlates of stereoscopic depth perception, to optimize the stereoscopic vision, and to objective evaluation of visual fatigue.
136 Head and neck oncology – 2010 , part I

Otolaryngol Pol 2010; 64 (3): 136-146 SUMMARY This article reviewed the current state of the art in head and neck oncology. These include very important and stimulating new areas of interest including the marked acceptance of chemoradiation in favor of surgery in patients with cancer of the head and neck. The concept of HPV as a cause of cancer of the oropharynx is relatively new and very important in the epidemiology of these tumors. New modalities such as PET CT scanning and robotic surgery are discussed and appear to be very important in management of cancer of the head and neck. Endoscopic endonasal skull base surgery is another new high technology contribution to the fi eld of head and neck surgery as is the use of endoscopic assisted thyroid surgery. These and other new concepts are discussed in this manuscript.
Culture or No Culture? A Latino Critical Research Analysis of Latino Persistence Research

The recent literature on Latino persistence does not take into account these students’ distinct cultural backgrounds. Most researchers of Latino persistence use the self-designation “Latino” as a proxy variable representing Latino culture. A Latino Critical Theory (LatCrit) lens is applied to the persistence literature to demonstrate the need to infuse these studies with a focus on Latino culture.
Prismatic Adaptation and Visuo-Motor Skils in Children with Learning Disabilities

Two groups of children, both presenting difficulties in academic achievement, but one with and one without visuomotor impairments, were assessed. The purpose of the study was to determine whether poor drawing ability was related to any of the following: disorders of perceptual analysis, disorders of motor or executive skills, disorders of perception or motor integration. A guessing-game technique involving the serial analysis of a visual array, was given to measure the perceptual competence of a child. Motor skills were assessed by a simple motor test which did not depend on visual input. Perceptual-motor integration was explored through the use of prismatically induced visual distortion. The results were interpreted to indicate that the child who draws poorly is characterized by disorders of perceptual analysis and visuomotor integration.
Genetic bottleneck in the threatened western population of European mink Mustela lutreola

Abstract The western population of European mink Mustela lutreola has recently suffered a severe decline in over more than 50% of its range, probably disappearing from Brittany in 1992 and from Pays de Loire in 1997. Allozyme electrophoresis on 38 presumptive loci showed that the proportion of polymorphic loci reached only 10.5% at P < 0.01 level in the European mink. Observed heterozy‐gosity averaged Ho = 0.02 and expected heterozygosity HE = 0.038 but the F1s index reached 0.48, revealing a considerable deficit. The low genetic variability might be due to previous bottlenecks. Demographic depletion in Mustela lutreola resulted in a loss of genetic diversity emphasising that reproductive exchanges were altered and worsening the risk of extinction of this vulnerable population.
Clarifying the Concept of Communities of Practice in Sport

In an attempt to describe learning outside of the usual official curriculum, concepts such as workplace learning, nonformal learning, informal learning, and incidental learning have been used in the fields of teacher education, workplace pedagogy, and sport. These ‘outside-of-the-classroom’ learning opportunities are characterized by the important role that peers play in the learning process. Participation in communities of practice (CoPs) provides one such opportunity for learning. Recent interest in this concept for coach education and in sport has resulted in an increasing number of studies in which researchers promote CoPs, but not all these studies operationalise CoPs clearly and according to Etienne Wenger's framework To clarify this situation and further stimulate the discussion around the potential of CoPs in sport, we present a brief history and description of the concept, compare it with related notions, and describe some recent studies on CoPs in sport.
Optimal relay assignment for secrecy capacity maximization in cooperative ad-hoc networks

Physical layer security has emerged as a key technique for providing trustworthy and reliable future wireless networks and has witnessed a significant growth in the past few years. In this paper, we aim to improve the physical layer security and provide secure cooperative communication through cooperative relay assignment. By characterizing the security performance of the system by secrecy capacity, we study the secrecy capacity maximization problem in cooperative ad hoc networks with the involvement of multiple malicious eavesdroppers. Specifically, we propose a system model where a set of relay nodes can be exploited by multiple source-destination pairs to achieve physical layer security. We theoretically present a corresponding formulation for the secrecy capacity maximization problem. Then we develop an optimal relay assignment algorithm to solve the problem in polynomial time. The basic idea behind our proposed algorithm is to boost the capacity of the primary channel by simultaneously decreasing the capacity of the eavesdropping channel. Through extensive experiments, we validate that our proposed relay assignment algorithm significantly increase the system secrecy capacity under various network settings.
Statistical machine translation adding pattern-based machine translation in Chinese-English translation

We have developed a two-stage machine translation (MT) system. The first stage is a rule-based machine translation system. The second stage is a normal statistical machine translation system. For Chinese-English machine translation, first, we used a Chinese-English rule-based MT, and we obtained ”ENGLISH” sentences from Chinese sentences. Second, we used a standard statistical machine translation. This means that we translated ”ENGLISH” to English machine translation. W e believe this method has two advantages. One is that there are fewer unknown words. The other is that it produces structured or grammatically correct sentences. From the results of experiments, we obtained a BLEU score of 0.3151 in the BTEC-CE task using our proposed method. In contrast, we obtained a BLEU score of 0.3311 in the BTEC-CE task using a standard method (moses). This means that our proposed method was not as effective for the BTEC-CE task. Therefore, we will try to improve the performance by optimizing parameters.
A Naturally Occurring Isoform Inhibits Parathyroid Hormone Receptor Trafficking and Signaling

Parathyroid hormone (PTH) regulates calcium homeostasis and bone remodeling through its cognitive receptor (PTHR). We describe here a PTHR isoform harboring an in‐frame 42‐bp deletion of exon 14 (Δe14‐PTHR) that encodes transmembrane domain 7. Δe14‐PTHR was detected in human kidney and buccal epithelial cells. We characterized its topology, cellular localization, and signaling, as well as its interactions with PTHR. The C‐terminus of the Δe14‐PTHR is extracellular, and cell surface expression is strikingly reduced compared with the PTHR. Δe14‐PTHR displayed impaired trafficking and accumulated in endoplasmic reticulum. Signaling and activation of cAMP and ERK by Δe14‐PTHR was decreased significantly compared with PTHR. Δe14‐PTHR acts as a functional dominant‐negative by suppressing the action of PTHR. Cells cotransfected with both receptors exhibit markedly reduced PTHR cell membrane expression, colocalization with Δe14‐PTHR in endoplasmic reticulum, and diminished cAMP activation and ERK phosphorylation in response to challenge with PTH. Δe14‐PTHR forms heterodimers with PTHR, which may account for cytoplasmic retention of PTHR in the presence of Δe14‐PTHR. Analysis of the PTHR heteronuclear RNA suggests that base‐pair complementarity in introns surrounding exon 14 causes exon skipping and accounts for generation of the Δe14‐PTHR isoform. Thus Δe14‐PTHR is a poorly functional receptor that acts as a dominant‐negative of PTHR trafficking and signaling and may contribute to PTH resistance. © 2011 American Society for Bone and Mineral Research.
Tai O village

• This article offers a socio-cultural perspective on what happens to a once thriving fishing village when the traditional fishermen retire, their children seek safer and more lucrative work in an adjacent cosmopolitan city, and the population diminishes leaving the village facing economic hardship and general decline. The article explores these issues and the related aspects of ‘place’ and ‘space’ in the context of Tai O village, Lantau Island, Hong Kong. The article treats ‘space’ as a blend of social experience and physical structure in order to examine the tensions between the vernacular architecture of Tai O and the Hong Kong government’s plans to ‘revitalize’ the area. •
The use of online technology in the modus operandi of female sex offenders

Abstract In this review we examine the methods by which female sexual offenders may use communications technologies such as the internet in their offending behaviours. We outline the context of sexual abuse of children both by female perpetrators and by those using the internet. The topic is examined based on three criminogenic areas highlighted by Lambert and O'Halloran: (1) interpersonal/socialization deficits; (2) deviant sexual arousal; and (3) cognitive distortions and recognition barriers. We include elements drawn from anonymized clinical cases of female-perpetrated sexual abuse of children involving online technology. We present the argument that the characteristics of this population are likely to suggest that clinicians assessing cases of this nature may find it more useful to refer to the literature on female sexual offenders rather than that of male internet offenders.
Various Slotted UWB Antenna Design

This paper presents various slotted antenna. The proposed antenna is designed in order to meet Ultra Wideband (UWB) requirements and applications. This antenna has small in size enabling it to be fixed into Wireless Personal Area Network (WPAN) devices. There are three types of proposed slotted antennas; T slotted for patch and feeding strip, couple a ring and L slots, and dual asymmetry L slots. From the simulation results, matching bandwidth is due to the shape of the antenna close to the feeding point, where currents are the strongest. It is shown that to better control an antenna behavior, it is necessary to observe the current distributions which give most contribution on matching performance. The T slot on the feeding strip produces more vertical current thus improve the matching impedance performance at higher frequencies, the ring slot with the open angle of 90o and radius (r1) of 3 mm has shown an improvement to the return loss at the lower resonance of 5 GHz and the upper resonance of 10 GHz, the dual asymmetry L slot on rectangular patch has shown multiple resonances. Their simulated return loss and radiation pattern meet the UWB requirements. The slot types are as novelty for this work.
