Impaired postnatal hepatocyte proliferation and liver regeneration in mice lacking c‐jun in the liver

Mice lacking the AP‐1 transcription factor c‐jun die at mid‐gestation showing heart defects and impaired hepatogenesis. To inactivate c‐jun in hepatocytes, mice carrying a floxed c‐jun allele were generated. Perinatal liver‐specific c‐jun deletion caused reduced hepatocyte proliferation and decreased body size. After partial hepatectomy, half of the mutants died and liver regeneration was impaired. This phenotype was not present in mice lacking the N‐terminal phosphorylation sites of c‐Jun. The failure to regenerate was accompanied by increased cell death and lipid accumulation in hepatocytes. Moreover, cyclin‐dependent kinases and several cell cycle regulators were affected, resulting in inefficient G1–S phase progression. These studies identify c‐Jun as a critical regulator of hepatocyte proliferation and survival during liver development and regeneration.
Kalman Filter as a pre-processing technique to improve the support vector machine

The Support Vector Machine is widely used as a classification tool to analyze data and recognize patterns. In certain applications of Support Vector Machine, noisy data can greatly affect accuracy and performance. To improve the accuracy of the system, the Kalman Filter has been proposed as a suitable pre-processing technique which can be implemented before using the Support Vector Machine to classify the information. This system has been tested using a dataset obtained from a pipeline defect monitoring system in the department's pipeline laboratory. This test rig uses long range ultrasonic testing to detect minor defects inside a stainless steel pipe. MATLAB simulations show promising results where Kalman Filter and Support Vector Machine combination in a single system produced higher accuracy compared to the discrete wavelet transform in a noisy environment.
Game theory and evolution : ® nite size and absolute ® tness measures

This article is concerned with the characterization and existence of evolutionarily stable strategies (ESS) in Games against Nature, a class of models described by ®nite size populations and absolute ®tness measures. We address these problems in terms of a new formalism which revolves around the concept evolutionary entropy, a measure of the diversity of options associated with a strategy ± pure strategies have zero entropy, mixed strategies positive entropy. We invoke this formalism to show that ESS are characterized by extremal states of entropy. We illustrate this characterization of ESS by an analysis of the evolution of the sex ratio and the evolution of seed size. Ó 2000 Elsevier Science Inc. All rights reserved.
The Body at War

The eighth Annual Conference of the University of Westminster’s Group for War and Culture Studies (GWACS) was held on 25 and 26 June 2004, in association this year with the Department of Sociology and Anthropology and the School for Journalism and Communications of Carleton University, Ottawa. Its theme, a fruitful one for this avowedly interdisciplinary project, was ‘The Body at War: Somatic Cartographies of Western Warfare in the 19th and 20th Centuries’. Participants included several from the United States and a few from France, although, unlike previous years, only one paper was given in French. Starting from the premise (in the Call for Papers) that ‘Throughout history, war has been conducted on, in and through the terrain of human bodies – individual, social, and culturally constructed [while] the human body, in turn, has served as a potent metaphor that continues to inform the ways we conceptualise, practise, and experience war’, they brought their varied expertise to bear in a number of thoughtful and thought-provoking ways. All six sessions were plenary, but a great deal was packed into the two days. As was to be expected, some of the 22 papers were more relevant to the themes of Medicine, Conflict and Survival than others, so that this report is necessarily selective. Quotations are taken from the programme and abstracts provided to those attending.
Hot spare components for performance-cost improvement in multi-core SIMT

Adding redundant components is a well known technique for replacing defective components either before shipment or in the field, resulting yield improvement and consequently cost reduction. However, most yield improvement strategies utilize redundant components only when another component fails (i.e., cold spares). In this paper, we investigate the cost and performance implications of employing hot spares in multi-core single-instruction, multiple-thread (SIMT) processors. Hot spares are available to increase yield (and reduce costs) when the components are defective; otherwise, they can be used to improve performance in the field. Starting with a baseline architecture with six cores, and 32 lanes each, we added three hot spare cores, with two lanes each. When we make the lanes of the hot spares available to replace defective lanes in the baseline cores, we observe that expected performance per cost improved more than 2.5 and 1.7 times relative to systems integrating no redundancy and cold spares, respectively.
Poster: Multi-antenna successive interference cancellation to improve reliability of V2V communication

V2V (Vehicle-to-Vehicle) communication has attracted attention to realize cooperative automated vehicles. In IEEE 802.11p, which standardizes physical and MAC layer specifications of V2V communication, broadcast CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is adopted as an access control scheme. CSMA/CA is a protocol that avoids collision in a distributed manner by carrier sensing and controlling the transmission timing of each node. However, when communication traffic increases, multiple signals from multiple vehicles collide and thus communication reliability decreases [1]. One of the solutions to this problem is simultaneous transmission and SIC (Successive Interference Cancellation), which is widely studied as a technique to enable receivers to demodulate multiple signals from a mixed signal [2]. However, SIC is not successful when the difference of the received power between signals in a mixed signal is small, e.g. when the hidden node problem occurs. On the other hand, diversity techniques such as multi-antenna system are widely used to mitigate collision caused by the hidden node problem and channel fluctuation caused by fading. Multi-antenna systems decrease PER (Packet Error Rate) by selecting and/or combining the multiple received signals.

Grip-strength, fatigue, and motor perseveration in anxious men without depression.

OBJECTIVE To investigate the influence of anxiety without depression on functional motor asymmetry in adult men. Thus, left-and right-hand grip strength, fatigue across trials, and motor perseveration was examined among 60 right-handed men, half of whom had been classified as anxious without depression (HI, n = 30) and the other half as nonanxious without depression (LO, n = 30). BACKGROUND There is substantial empirical support for the notion that individuals with negative affect experience relative right anterior activity. Moreover, previous studies using other groups of interest (e.g., depression and hostility) have found evidence of functional motor asymmetry that is supportive of relative right anterior activation during negative affect. Less is known about functional motor asymmetry among individuals that report anxiety without depression. METHOD To obtain indices of perseveration, strength, and fatigue, HI and LO anxious subjects were asked to successively squeeze a hand dynamometer. Dependent measures (in kg) were derived from performance with the left and right hands across trials. RESULTS In contrast to LO anxious subjects, HI anxious subjects did not demonstrate right-hand superiority for grip-strength. Moreover, significant positive correlations existed between grip strength and trait anxiety scores for LO anxious subjects, but not for HI anxious subjects. CONCLUSIONS The data are partially supportive of differences in functional motor asymmetry between HI and LO anxious individuals. The findings are interpreted as supportive of relative right anterior activity (and possibly decreased left anterior activity) among individuals that report elevated levels of anxiety. Implications for relative right-hemisphere activity and decreased left anterior activity are discussed, and alternative explanations are introduced.
An Open-loop Solution for a Stochastic Production-remanufacturing Planning Problem

A stochastic linear production planning problem with chance-constraints is introduced in order to provide a production plan that optimizes a reverse logistics system. Such a system is composed of two channels: in the forward channel, new and remanufactured products are produced and stored into a serviceable inventory unit. On the other hands, in the reverse channel, used and defected products are stored into the remanufacturable inventory unit. The uncertainties about the fluctuation of demand and the amount of returnable are the reason of the stochastic nature of the problem. Since global optimal solution is not easy to be achieved, an equivalent-deterministic suboptimal problem is proposed. An example of applicability of this deterministic problem is presented. In this example, two situations are proposed: the first considers that 50% of used-products are returnable; while the second considers 100%. It is assumed that 5% of new products are rejected during the quality inspection process. As a result, the example shows that, under certain circumstances, it is possible to improve the performance of the system by increasing the return rate for used-products.
OPTIMIZING THE ROTATION AND TRANSLATION OF FINGERPRINT IMAGES USING GENETIC ALGORITHM

In the minutiae-based fingerprint authentication system, the minutiae in the query image are required to be matched with the minutiae of the reference image that is stored in the database. Ideally, the minutiae extracted from the different impressions of the same fingerprint must match with each other, but practically, because of displacement, rotation, and other linear/ nonlinear distortions, minutiae extracted from different impressions of the same fingerprint do not match with each other. In order to maximize the number of matching minutiae, the alignment of the two fingerprints is required. Correctly aligning the fingerprints requires the translation and rotation to be recovered exactly. In this article, a new genetic-algorithm (GA)-based relative alignment algorithm for the alignment of reference and query fingerprint images is proposed. With the proposed algorithm there is no need to find the reference core or delta point because reliable detection of these reference points is a difficult task. In the proposed algorithm, all the three parameters x, y (translation), and θ (rotational) have been optimized separately. In order to improve the processing time, two acceleration steps have also been implemented. The experiments conducted on the FVC2002/Db1_a database reveal that a high accuracy has been achieved with the proposed method.
A Survey on Big Data Analytics: Challenges, Open Research Issues and Tools

Abstract: A huge repository of terabytes of data is generated each day from modern information systems and digital technologies such as Internet of Things and cloud computing. Analysis of these massive data requires a lot of efforts at multiple levels to extract knowledge for decision making. Therefore, big data analysis is a current area of research and development. The basic objective of this paper is to explore the potential impact of big data challenges, open research issues, and various tools associated with it. As a result, this article provides a platform to explore big data at numerous stages. Additionally, it opens a new horizon for researchers to develop the solution, based on the challenges and open research issues.
Low - k Polyimide/Silica Nanocomposites for Microelectronics Applications

The temperature and frequency dependence of dielectric permittivity of hybrid polyimide/silica nanocomposites, prepared by the in situ generation of crosslinked organosilicon nanophase by sol-gel techniques, was investigated by broadband dielectric relaxation spectroscopy. Dielectric permittivity decreases and its frequency and temperature dependence becomes weaker in the hybrids as compared to pure polyimide. The results are explained in terms of loose inner structure of the spatial aggregates of the organosilicon nanophase and reduced polymer dynamics in the hybrids. Water sorption measurements from the vapor phase show reduced water contents of the nanocomposites with respect to pure polyimide. These results suggest that the hybrids under investigation may have a reasonably good potential as low-k materials for microelectronics applications
Uncovering phase‐coupled oscillatory networks in electrophysiological data

Phase consistent neuronal oscillations are ubiquitous in electrophysiological recordings, and they may reflect networks of phase‐coupled neuronal populations oscillating at different frequencies. Because neuronal oscillations may reflect rhythmic modulations of neuronal excitability, phase‐coupled oscillatory networks could be the functional building block for routing information through the brain. Current techniques are not suited for directly characterizing such networks. To be able to extract phase‐coupled oscillatory networks we developed a new method, which characterizes networks by phase coupling between sites. Importantly, this method respects the fact that neuronal oscillations have energy in a range of frequencies. As a consequence, we characterize these networks by between‐site phase relations that vary as a function of frequency, such as those that result from between‐site temporal delays. Using human electrocorticographic recordings we show that our method can uncover phase‐coupled oscillatory networks that show interesting patterns in their between‐site phase relations, such as travelling waves. We validate our method by demonstrating it can accurately recover simulated networks from a realistic noisy environment. By extracting phase‐coupled oscillatory networks and investigating patterns in their between‐site phase relations we can further elucidate the role of oscillations in neuronal communication.

Efficient Chaotic Tent Map-based Image Cryptosystem

This paper presents an efficient chaotic image encryption cipher that is designed with the aim of improving the security and enhancing the encryption efficiency. In this paper, a chaotic tent map (CTM) is utilized to build a new digital chaotic image cryptosystem. The characteristics of CTM are very suitable for the design of encryption schemes. The security estimation of the proposed CTM-based image cryptosystem against brute-force, statistical, and differential attacks is investigated from strict cryptographic viewpoint. Experimental tests are performed with detailed analysis confirming the high security of the proposed CTM-based image cryptosystem.
Automatic Estimation of Perceived Sincerity from Spoken Language

Sincerity is important in everyday human communication and perception of genuineness can greatly affect emotions and outcomes in social interactions. In this paper, submitted for the INTERSPEECH 2016 Sincerity Challenge, we examine a corpus of six different types of apologetic utterances from a variety of English speakers articulated in different prosodic styles, and we rate the sincerity of each remark. Since the utterances and semantic meaning in the examined database are controlled, we focus on tone of voice by exploring a plethora of acoustic and paralinguistic features not present in the baseline model and how well they contribute to human assessment of sincerity. We show that these additional features improve the performance using the baseline model, and furthermore that conditioning learning models on the prosody of utterances boosts the prediction accuracy. Our best system outperforms the challenge baseline and in principle can generalize well to other corpora.
Association between sleep duration and haemoglobin A1c in young adults

Background Epidemiological and experimental evidence suggests that inadequate sleep can cause both obesity and impaired glucose tolerance. Short sleep duration in childhood appears to have a greater impact on the risk for adult obesity than adult sleep duration. The long-term effects of childhood sleep on glucose metabolism have not been investigated. The authors assessed the associations between childhood and adult sleep duration and adult glycosylated haemoglobin (HbA1c) levels. Methods An unselected cohort of 1037 individuals, born in Dunedin, New Zealand, between 1972 and 1973. Parent reports of times in bed at ages 5, 7, 9 and 11 were used to estimate childhood sleep duration. Adult sleep duration was estimated from self-reported times in bed at age 32. HbA1c levels were measured at age 32. Pregnant women and participants with diabetes were excluded from the analyses. Results Childhood sleep duration did not predict adult HbA1c. However, less time spent in bed at age 32 was associated with higher levels of HbA1c (p=0.002) and an increased risk of prediabetes (p=0.015). The inverse association between adult sleep times and HbA1c was independent of body mass index, smoking, socioeconomic status, shift work and symptoms of obstructive sleep apnoea. Conclusions Short sleep duration is associated with higher levels of HbA1c and an increased risk of prediabetes in young adults. The findings suggest that inadequate sleep impairs glucose control in the short term and may increase the risk for long-term health problems.
Ant Routing Protocol with Location Services in Intermittently Connected MANETs

Wireless and mobile networks seem to deliver tremendous uses. In its way, MANET leads to enormous real world applications. Routing allows us to implement many real world applications. Complete affinity in an infrequent network like ICMANET is highly impossible. Disconnected MANET is also known as ICMANET which is also a DTN (Delay Torrent Network) that supports for higher delays. It is laborious process to execute routing in a diffused network process to execute routing in a diffused network. To deliver the data packets towards the destined node to its best, a new strategy in routing called Ant routing protocol in concoction with storage strategy LoDis has been proposed. Despite of routing, security is still an unsolved problem. To evaluate this situation, this paper presents a methodology called agent technology which yields a secure routing. Hostile node in the network is spotted with the help of agent at each node. A cryptographic algorithm Advanced Encryption Standard (AES) is habituated to improve secure communication in wide range Mobility and total number of nodes in the network act as variables in examining the hostile nodes in the network to judge the standard of security. Improved performance along with the security is the point to be highlighted.
Factors affecting sperm fertilizing capacity in men infected with HIV

Studies on the sperm‐fertilizing capacity of HIV‐seropositive men show conflicting results for reasons that are not yet clear. The aim of this study was to investigate the effects and relationships of some factors such as patient age, CD4+ cells count, fathering offspring, concomitant sexually transmitted diseases (STD), and receipt of highly active anti‐retroviral therapy (HAART) on sperm fertilizing capacity. Semen samples were collected from 33 HIV‐seropositive men. Data on the above factors were acquired from a self‐designed questionnaire. Computer‐assisted sperm analysis, a hypo‐osmotic swelling, and zona‐free hamster oocyte penetration tests were performed according to criteria of the World Health Organization. CD4+ cells in peripheral blood were examined using a flow cytometric (FCM) analyzer. Sperm vitality, sperm motility (grades a + b), total sperm motility, and sperm penetration rates were significantly higher in patients whose CD4+ counts were ≧350/µl than in those whose CD4+ counts were <350/µl (P < 0.05), and the parameters mentioned above were also significantly correlated with CD4+ cell number (all P < 0.05). Significant differences in total sperm count and sperm tail swelling rate between patients co‐infected with STD and without STD were observed (P < 0.05). Sperm penetration rate in patients receiving HAART was significantly higher than in those not receiving HAART (P < 0.05). Blood CD4+ cell counts are an important indicator for evaluating sperm fertilizing capacity of HIV‐seropositive men. After receiving HAART, the sperm penetration rate of HIV‐seropositive men can be improved. J. Med. Virol. 86:1467–1472, 2014. © 2014 Wiley Periodicals, Inc.
An improved division algorithm with a small lookup table and its implementation

This paper presents an improved Hung's division algorithm, which can produce results with very low latency. In our method, a computing error bound is given, and a set of the optimum design parameters is provided. According to our design approach, hardware scale is significantly reduced, comparing with the original method. Our algorithm has been implemented on Xilinx FPGA, as kernel of channel estimator in an OFDM receiver. The results of hardware simulation show that the divider error, which is well controlled by our error bounds, satisfies our design requirements.
Polarization Engineering on Buffer Layer in GaN-Based Heterojunction FETs

To improve the pinched-off characteristics of an AlGaN/GaN heterojunction field effect transistor (HJFET), the conduction band potential of an incorporated ALxGa1-xN buffer is designed to be upwardly convex in a band diagram. This approach utilizes the polarization effects specific to GaN-based materials by lowering the Al content x from 30% to 5% almost linearly toward the front side. Fabricated field effect transistors (FETs) adopting the designed buffer have demonstrated the following advanced characteristics in comparison to those of a FET adopting a conventional GaN buffer: less than one-tenth of the buffer leakage current, a gate-to-drain breakdown voltage BVgd twice or more as high, and remarkably improved carrier confinement and pinched-off behavior. The FETs are operated in an enhancement mode with a gate-to-channel distance thick enough to prevent tunneling current through the gate.
