Dystropathology Increases Energy Expenditure and Protein Turnover in the Mdx Mouse Model of Duchenne Muscular Dystrophy

The skeletal muscles in Duchenne muscular dystrophy and the mdx mouse model lack functional dystrophin and undergo repeated bouts of necrosis, regeneration, and growth. These processes have a high metabolic cost. However, the consequences for whole body energy and protein metabolism, and on the dietary requirements for these macronutrients at different stages of the disease, are not well-understood. This study used juvenile (4- to 5- wk-old) and adult (12- to 14-wk-old) male dystrophic C57BL/10ScSn-mdx/J and age-matched C57BL/10ScSn/J control male mice to measure total and resting energy expenditure, food intake, spontaneous activity, body composition, whole body protein turnover, and muscle protein synthesis rates. In juvenile mdx mice that have extensive muscle damage, energy expenditure, muscle protein synthesis, and whole body protein turnover rates were higher than in age-matched controls. Adaptations in food intake and decreased activity were insufficient to meet the increased energy and protein needs of juvenile mdx mice and resulted in stunted growth. In (non-growing) adult mdx mice with less severe dystropathology, energy expenditure, muscle protein synthesis, and whole body protein turnover rates were also higher than in age-matched controls. Food intake was sufficient to meet their protein and energy needs, but insufficient to result in fat deposition. These data show that dystropathology impacts the protein and energy needs of mdx mice and that tailored dietary interventions are necessary to redress this imbalance. If not met, the resultant imbalance blunts growth, and may limit the benefits of therapies designed to protect and repair dystrophic muscles.
HESS J1616−508: likely to be powered by PSR J1617−5055

HESS J1616 _ 508 is one of the brightest emitters in the TeV sky. Recent observations with the IBIS/ISGRI telescope onboard the INTEGRAL spacecraft have revealed that a young, nearby and energetic pulsar, PSR J1617 _ 5055, is a powerful emitter of soft γ-rays in the 20-100 keV domain. In this paper, we present an analysis of all available data from the INTEGRAL, Swift, BeppoSAX and XMM-Newton telescopes with a view to assessing the most likely counterpart to the High Energy Stereoscopic System (HESS) source. We find that the energy source that fuels the X/y-ray emissions is derived from the pulsar, both on the basis of the positional morphology, the timing evidence and the energetics of the system. Likewise the 1.2 per cent of the pulsar's spin-down energy loss needed to power the 0.1-10 TeV emission is also fully consistent with other HESS sources known to be associated with pulsars. The relative sizes of the X/y-ray and very high energy sources are consistent with the expected lifetimes against synchrotron and Compton losses for a single source of parent electrons emitted from the pulsar. We find that no other known object in the vicinity could be reasonably considered as a plausible counterpart to the HESS source. We conclude that there is good evidence to assume that the HESS J1616-508 source is driven by PSR J1617-5055 in which a combination of synchrotron and inverse-Compton processes combine to create the observed morphology of a broad-band emitter from keV to TeV energies.
A Simple Prior for Audio Signals

We propose a simple prior for restoration problems involving oscillatory signals. The prior makes use of an underlying analytic frame decomposition with narrow subbands. Other than this, the prior does not have any other parameters, which makes it simple to use and apply. We demonstrate the utility of the proposed prior through some real audio restoration experiments.
Comparison of Ultrasonographic Architectural Properties and Balance Ability Based on the Muscle Contraction of Chronic Stroke Patients

The purpose of this study is to compare the ultrasonographic architectural properties of muscles and balance ability based on the muscle contraction of chronic stroke patients. The subjects of this study were 30 chronic stroke patients were divided into 3 classes based on the Modified Ashworth Scale (MAS), with 10 patients in each class. Ultrasonographic architectural properties and balance ability were measured using ultrasonographic and a balance measurement system, respectively. According to the study result, as the spasticity level increased, the muscle thickness, pennation angle, and fascicle length significantly decreased (p<.001), whereas the sway area, sway path, and sway average speed significantly increased (p<.001), based on each condition. This study presented that pathokinesiological characteristics of the medial gastrocnemius muscle should be taken into account in chronic stroke patients balance training.
Notice of RetractionStability of the Euler-Maruyama method for hybrid stochastic differential delay equations

In the paper the main aim is to investigate the stability of the Euler-Maruyama method for the hybrid stochastic differential delay equations. The mean square stable condition of the analytical solution for a linear hybrid stochastic differential delay equations is obtained by Razumikhin theorem, and we prove that the condition preserves the stability property of the numerical scheme. A numerical example is provided to illustrate the theoretical results.
Iron as the Key Modulator of Hepcidin Expression in Erythroid Antibody-Mediated Hypoplasia

Erythroid hypoplasia (EH) is a rare complication associated with recombinant human erythropoietin (rHuEPO) therapies, due to development of anti-rHuEPO antibodies; however, the underlying mechanisms remain poorly clarified. Our aim was to manage a rat model of antibody-mediated EH induced by rHuEPO and study the impact on iron metabolism and erythropoiesis. Wistar rats treated during 9 weeks with a high rHuEPO dose (200 IU) developed EH, as shown by anemia, reduced erythroblasts, reticulocytopenia, and plasmatic anti-rHuEPO antibodies. Serum iron was increased and associated with mRNA overexpression of hepatic hepcidin and other iron regulatory mediators and downregulation of matriptase-2; overexpression of divalent metal transporter 1 and ferroportin was observed in duodenum and liver. Decreased EPO expression was observed in kidney and liver, while EPO receptor was overexpressed in liver. Endogenous EPO levels were normal, suggesting that anti-rHuEPO antibodies blunted EPO function. Our results suggest that anti-rHuEPO antibodies inhibit erythropoiesis causing anemia. This leads to a serum iron increase, which seems to stimulate hepcidin expression despite no evidence of inflammation, thus suggesting iron as the key modulator of hepcidin synthesis. These findings might contribute to improving new therapeutic strategies against rHuEPO resistance and/or development of antibody-mediated EH in patients under rHuEPO therapy.
Offline Handwritten Signatures Classification Using Wavelet Packets and Level Similarity Based Scoring

—Offline Signature Classification has been extensively studied for many years. The challenge in this area is the correct classification of skilled forgeries which are the result of deliberate practice to imitate the signatures of any person. In this paper the preprocessed images of genuine handwritten signatures are subjected to analysis by Wavelet Packets. A regular wavelet like db4 has been used to do the decomposition upto four levels. The resulting decomposed signal is further subjected to wavelet multiscale principal component analysis done for ten levels. The principal components are chosen according to the kais rule. The selected principal components consist of details at ten different levels and one approximation for each signature image. For a given test signature image the principal components are extracted in the same way and the principal components at each level are compared against the mean principal components of the genuine signatures at the corresponding level and the difference is within the permissible range, then a score is assigned. The collective score obtained due to all levels is used to classify the signature as genuine or forgery. The proposed system has a FAR of 12% and a FRR of 8%.
Genomic Characterization of Campylobacter jejuni Strain M1

Campylobacter jejuni strain M1 (laboratory designation 99/308) is a rarely documented case of direct transmission of C. jejuni from chicken to a person, resulting in enteritis. We have sequenced the genome of C. jejuni strain M1, and compared this to 12 other C. jejuni sequenced genomes currently publicly available. Compared to these, M1 is closest to strain 81116. Based on the 13 genome sequences, we have identified the C. jejuni pan-genome, as well as the core genome, the auxiliary genes, and genes unique between strains M1 and 81116. The pan-genome contains 2,427 gene families, whilst the core genome comprised 1,295 gene families, or about two-thirds of the gene content of the average of the sequenced C. jejuni genomes. Various comparison and visualization tools were applied to the 13 C. jejuni genome sequences, including a species pan- and core genome plot, a BLAST Matrix and a BLAST Atlas. Trees based on 16S rRNA sequences and on the total gene families in each genome are presented. The findings are discussed in the background of the proven virulence potential of M1.
User History Based Mail Filtering Process

Email spams are probable intimidation to an email user. In this paper we deal with spams which may slither through filters into client's mailbox (false negative). We use client's history to solve the above mentioned problem. For a client a particular message can be important while for some other client they may be unimportant. Other than filtered spam generally a user decides which type of message is spam by flagging it. Our novel approach reduces this effort and client need not see all mails and manually flag them as spam because this filtering system and algorithms used in it will separate all those junks so that the client is left with only those mails which are useful for him/her. We propose using, part of speech tagging module of Natural Language Processing and some other discussed algorithms. This approach is not only saving time of a client but is also acting as a good mail filter.
Adolescent girls’ interpretation of sexuality found in media image

Sexuality among females in Hong Kong is influenced both by the Chinese cultural trait of conservatism and the western cultural trait of active agency. The current study examines adolescent girls' negotiation of their sexuality through consumption of female images in media. A qualitative study was conducted. Twenty adolescent girls aged 15 to 18 in Hong Kong were asked to take pictures from the media they consumed that could illustrate "what girls or women should or should not be; and what girls or women should or should not do". Interviewees' responses to sexuality issues were examined. Analysis of interviews and images captured found six dominant themes on sexuality, including (1) defining and evaluating sexiness, (2) intimate relationship, (3) marriage, (4) pregnancy, (5) deviant sexual relationship, and (6) health concerns for women. Interviewees showed clear and vivid distinction between "good" and "bad" sexiness. Glamorous presentation of female bodies was glorified, while revealing the female body solely to attract male attention or in the wrong context was scorned. Most of the interviewees expressed aspirations for romantic heterosexual relationships, and professed the desire to be wives and mothers. Being single and child-free was not registered as a dominant way of defining respondents as females. Adolescent girls' perception of sexuality embraced traditional as well as modern values.
User Resistance Behaviors and Management Strategies in IT-Enabled Change

Information Technology (IT) is often used in organizations as a tool to enable change. However, as organizations switch to different vendors, upgrade their systems, or implement new systems, widespread user resistance is often encountered. Resistant behaviors often occur in these large-scale system implementations because the implementation transforms the jobs of employees and mandates system use. In order to understand resistant behaviors better as well as management strategies to minimize these behaviors, this study uses a focus group and qualitative semi-structured interviews. Based on the data collection, this study first creates a resistant behavior framework and a management strategy framework using a data-driven approach. The findings from the user resistance behaviors are classified into four categories. Also, eight preferred management strategies are identified by users, which are grouped into three categories. Then, the Framework-based Theory of User Resistance is proposed, which examines the causes and moderating forces that affect resistant behaviors. The practical implications of these frameworks also are described. User Resistance Behaviors and Management Strategies in IT-Enabled Change
A CPK-Based Security Scheme at Network Layer

A novel security scheme at network layer is proposed. It provides mutual authentication between the communication partners by adopting the effective combined public key (CPK) algorithm, which is an identity-based cryptosystem. And each outgoing packet can be digitally signed with CPK-based signature, which uses elliptic curve digital signature algorithm (ECDSA) and may offer equal security with a far smaller key size than RSA’ s, to provide packet-level nonrepudiation when necessary. In addition, the data transmitted over the network can be encrypted for better security via a symmetric or asymmetric cipher. Compared to similar network security solutions, the proposed scheme is easier to configure and more flexible. The experimental results show that the scheme owns better efficiency.
Condition Monitoring of Arrow Dynamic and Drive Train in Wind Turbine using Artificial Intelligence

In order to be economically competitive, various control systems are used in Wind turbine. These systems makes the wind turbine to work efficiently and produce maximum output at different speed. In this paper an adaptive control based on radial-basis function neural network are used for different operation of variable speed wind turbine including torque control at lower speed, pitch control at higher speed and smooth transition between these two modes. The adaptive neural network control approximates the nonlinear dynamics of wind turbine based on input/output measurement. One of the most important features in the smart gird is to integrate the state-of-the-art communication technologies to increase the electrify generation. In offshore wind farms, data communications would rely on wireless techniques. The wireless communication technology has several advantages over the wires or meter counterpart. However, the impact of atmospheric turbulence on wired must be well understood first. In this project, the performance of wireless links subject to weak influence in generator, turbine is monitored. The metrics are analytically and numerically evaluated.
From anatomical to biological target volumes: the role of PET in radiation treatment planning

Progress in radiation oncology requires a re-evaluation of the methods of target volume delineation beyond anatomical localization. New molecular imaging techniques for tumour visualisation such as positron emission tomography (PET) provide insight into tumour characteristics and can be complementary to the anatomical data of computed tomography or magnetic resonance imaging. In this review, three issues are discussed: First, can PET identify a tumour more accurately? Second, can biological tumour characteristics be visualised? Third, can intratumoural heterogeneity of these characteristics be identified?
On Extensible Networks for Embedded Systems

When designing a distributed computing-system, the communication networks are a key determining factor for system's performance. A common approach is to minimize bandwidth-consumption, while other important objectives -- maintainability, extensibility, robustness -- get less attention in the literature. In this work we provide a design-methodology how to efficiently balance these conflicting objectives. We build an initial network configuration by applying heuristics. Then, we refine this configuration by using optimization strategies which address the multi-objective optimization problem. By doing so, the network configuration not only satisfies the requirements of the current communication-demand, but it is also prepared to handle additional future communication-demand. Experimental results from an automotive case-study show that extensibility can be significantly improved (up to 44%) while trading only a little bandwidth-efficency (1% deteriation).
Automated industrial robot path planning for spray painting process: A review

Industrial robots are widely used to paint final products in many industries, such as automotive and furniture etc. Robot path planning based on the CAD models of parts for spray painting is critical for product quality, process cycle time and material waste etc. Currently automated robot path planning has always caused a bottleneck for the spray painting processes because typical manual teaching methods are time consuming, error-prone and skill dependent. Thus, it is essential to develop automated tool path planning methods to replace manual tool path planning ones in order to reduce the cost and improve product quality. This challenging research topic has been receiving more and more attention from both academia and industry. Therefore, a review of automated tool path planning methods is necessary to investigate the advantages and disadvantages of the current techniques.
A Prototype for General Planning

Planning problems, in which a sequence of actions are sought to go from a given state to a desired final state, or goal, have traditionally been hard to handle computationally. In particular and in the most usual case, the goal is not just to find a satisfying plan, but rather to find the best one. Searching for such optimum, i.e. shortest, plan, increases complexity even further. Frequently, specialised systems are developed for particular problems with ad-hoc solutions, losing generality and flexibility. Alternatively, a generalised naive solution is adopted, losing efficiency. Constraint programming (CP) has been used successfully to declaratively and efficiently solve large combinatorial problems. Unfortunately, modelling such problems in CP, requires declaring, a priori, a fixed number of variables with specified types and domains. This makes it hard to express planning problems, where the number of actions, possibly of different types, to perform is not known a priori. In this paper, we describe how planning problems can be declaratively and efficiently solved with an example system we developed based on logic programming and term rewriting. Additionally we show that such a system can also be used for general declarative programming, gaining in ease of use, flexibility, maintenance and debugging
DETECTION OF WIDESPREAD HYDRATED MATERIALS ON VESTA BY THE VIR IMAGING SPECTROMETER ON BOARD THE DAWN MISSION

Water plays a key role in the evolution of terrestrial planets, and notably in the occurrence of Earth's oceans. However, the mechanism by which water has been incorporated into these bodies—including Earth—is still extensively debated. Here we report the detection of widespread 2.8 μm OH absorption bands on the surface of the asteroid Vesta by the VIR imaging spectrometer on board Dawn. These observations are surprising as Vesta is fully differentiated with a basaltic surface. The 2.8 μm OH absorption is distributed across Vesta's surface and shows areas enriched and depleted in hydrated materials. The uneven distribution of hydrated mineral phases is unexpected and indicates ancient processes that differ from those believed to be responsible for OH on other airless bodies, like the Moon. The origin of Vestan OH provides new insight into the delivery of hydrous materials in the main belt and may offer new scenarios on the delivery of hydrous minerals in the inner solar system, suggesting processes that may have played a role in the formation of terrestrial planets.
On the Brink of Catastrophe

What motivates man to participate? Why do many choose to be sedentary in spite of the better health, fitness, strength, relaxation, and other outcomes known to occur with participation? Although there is researchsupported knowledge of why man SHOULD play, it appears that man does not play primarily for health and fitness. Therefore, there must be other reasons; however, very little is known about why man DOES play. It is possible that needs of which the participant is unaware are being gratified. With sport such a dominant aspect of American life, investigators are not content with knowing what sport does physiologically for the participant but also are questioning why man plays and participates in the sports that he does. Recently, investigators have
Multiobjective genetic programming approach to evolving heuristics for the bounded diameter minimum spanning tree problem: MOGP for BDMST

The bounded-diameter (or diameter-constrained) minimum spanning tree (BDMST) problem is a well-studied combinatorial optimization problem for which several heuristics such as: one-time tree construction (OTTC), center based tree construction(CBTC), iterative refinement (IR) and randomized greedy heuristics (RGH) have been developed. Very little work, however, has been done on producing heuristics for BDMSTs using evolutionary algorithms. In this paper we have used multiobjective genetic programming (MOGP) to explore the evolution of a set of heuristics for the BDMST problem. The quality of the Pareto fronts obtained from the MOGP-evolved heuristics is comparable to, or in some cases better than, the Pareto fronts generated by established, hand-crafted heuristics. MOGP is thus a very promising technique for finding heuristics for BDMSTs and more general multiobjective combinatorial optimizations.
