Effects of Hydration State and Resistance Exercise on Markers of Muscle Damage

Yamamoto, LM, Judelson, DA, Farrell, MJ, Lee, EC, Armstrong, LE, Casa, DJ, Kraemer, WJ, Volek, JF, and Maresh, CM. Effects of hydration state and resistance exercise on markers of muscle damage. J Strength Cond Res 22(5): 1387-1393, 2008-It is well established that resistance exercise can damage muscle tissue, but the combined effects of hypohydration and resistance exercise on muscle damage are unclear. Two common circulating markers of muscle damage, myoglobin (Mb) and creatine kinase (CK) may be attenuated by fluid ingestion post-exercise. The purpose of this study was to examine the combined effect of resistance exercise and hydration state on muscle damage. Seven healthy resistance-trained males (age = 23 ± 4 years; body mass = 87.8 ± 6.8 kg; body fat = 11.5 ± 5.2%) completed 3 identical resistance exercise bouts (6 sets of up to 10 repetitions of the back squat) in different hydration states: euhydrated (HY0), hypohydrated ∼2.5% body mass (HY2.5), and hypohydrated ∼5.0% body mass (HY5). Subjects achieved desired hydration states via controlled water deprivation, exercise-heat stress, and fluid intake. Both Mb and CK were measured during euhydrated rest (PRE). Mb was also measured immediately post-exercise, 1 hour (+1H) and 2 hours (+2H) post-exercise; CK was measured at 24 and 48 hours post-exercise. Body mass decreased 0.2 ± 0.4%, 2.4 ± 0.4%, and 4.8 ± 0.4% during HY0, HY2.5, and HY5, respectively. Mb concentrations increased significantly (effect size ≥1, p < 0.05) from PRE (2.6 ± 1.1, 3.5 ± 2.8, and 3.2 ± 1.6 nmol·L−1) to +1H (5.3 ± 3.4, 6.8 ± 3.2, and 7.6 ± 2.8 nmol·L−1), and +2H (5.5 ± 3.8, 6.2 ± 3.0, and 7.2 ± 3.0 nmol·L−1) for HY0, HY2.5, and HY5, respectively, but were not significantly different between trials. CK concentrations remained within the normal resting range at all time points. Thus, hypohydration did not enhance muscle damage following the resistance exercise challenge. Despite these results, athletes are encouraged to commence exercise in a euhydrated state to maximize endogenous hormonal, mechanical, and metabolic benefits.
Covariance matrix estimation and linear process bootstrap for multivariate time series of possibly increasing dimension

Multivariate time series present many challenges, especially when they are high dimensional. The paper’s focus is twofold. First, we address the subject of consistently estimating the autocovariance sequence; this is a sequence of matrices that we conveniently stack into one huge matrix. We are then able to show consistency of an estimator based on the so-called flat-top tapers; most importantly, the consistency holds true even when the time series dimension is allowed to increase with the sample size. Secondly, we revisit the linear process bootstrap (LPB) procedure proposed by McMurry and Politis (Journal of Time Series Analysis, 2010) for univariate time series. Based on the aforementioned stacked autocovariance matrix estimator, we are able to define a version of the LPB valid for multivariate time series. Under rather general assumptions, we show that our multivariate linear process bootstrap (MLPB) has asymptotic validity for the sample mean in two important cases: (a) when the time series dimension is fixed, and (b) when it is allowed to increase with sample size. As an aside, in case (a) we show that the MLPB works also for spectral density estimators which is a novel result even in the univariate case. We conclude with a simulation study that demonstrates the superiority of the MLPB in some important cases.
Membranes in the miotic apparatus of barley cells

Membranes in the mitotic apparatus have been investigated ultrastructually in dividing cells of barley (Hordeum vulgare). After osmium tetroxide- potassium ferricyanide or ferrocyanide postfixation (OsFeCN) of material that had been fixed in glutaraldehyde in the presence of Ca(++), the nuclear envolope (NE)-endoplasmic reticulum (ER) complex is selectively stained, permitting observations on the cellular pattern and structural ramifications of this membrane system that have not been previously recognized. Specifically, it is observed that membrane system that have not been previously recognized. Specifically, it is observed that during mitosis the NE-ER forms a continuous membrane system that ensheathes and isolates the mitotic apparatus (MA). Elements of ER progressively accumulate in the region of the spindle pole, becoming most concentrated by early anaphase. Within the MA itself, there are striking spindle- membrane associations; in particular, tubular elements of predominantly smooth NE-ER invade the spindle interior selectively along kinetochore microtubules. The membrane elements at the pole and surrounding the MA consist of tubular reticulum and fenestrated lamellae. Membranes of the MA thus resemble in considerable detail the tubular network and fenestrated elements of the sarcoplasmic reticulum of muscle. It is suggested that the NE-ER of the dividing barley cell may function in one or both of the following ways: (a) to control the concentration of free Ca(++) in the MA and (b) to serve as an anchor to chromosome motion.
Increasing the Efficiency and Responsiveness of Mobile Applications with Preemptable Code Offloading

Mobile applications are getting more and more sophisticated and demanding. Although the processing, memory, and storage resources of mobile devices are constantly increasing to enable such resource-demanding mobile applications, battery capacity is still the main limiting factor. To solve this problem, mobile code offloading approaches can be used to offload parts of a mobile application to remote servers and utilize the resources of cloud services. In this paper, we propose a novel code offloading approach that makes code offloading robust against communication link failures, which are still a major problem of mobile systems. To this end, we propose preemptable code offloading. It allows for interrupting the offloading process and continuing the remote execution locally after a link failure, without abandoning the complete result calculated remotely so far. The basic idea of our approach is to create safe-points of the remote execution and transmit these intermediate results back to the mobile device. After a link failure, the mobile device can now continue execution from the last transmitted safe-point. Although safe-points induce communication and energy overhead, our evaluations show that using an optimized safe-point schedule this overhead quickly pays off under link failures. Besides reducing the overall energy consumption significantly, responsiveness also benefits from safe-points by meeting given execution deadlines after link failures.
Cholinergic and ghrelinergic receptors and KCNQ channels in the medial PFC regulate the expression of palatability

The medial prefrontal cortex (mPFC) is a key brain region for the control of consummatory behavior. Neuronal activity in this area is modulated when rats initiate consummatory licking and reversible inactivations eliminate reward contrast effects and reduce a measure of palatability, the duration of licking bouts. Together, these data suggest the hypothesis that rhythmic neuronal activity in the mPFC is crucial for the control of consummatory behavior. The muscarinic cholinergic system is known to regulate membrane excitability and control low-frequency rhythmic activity in the mPFC. Muscarinic receptors (mAChRs) act through KCNQ (Kv7) potassium channels, which have recently been linked to the orexigenic peptide ghrelin. To understand if drugs that act on KCNQ channels within the mPFC have effects on consummatory behavior, we made infusions of several muscarinic drugs (scopolamine, oxotremorine, physostigmine), the KCNQ channel blocker XE-991, and ghrelin into the mPFC and evaluated their effects on consummatory behavior. A consistent finding across all drugs was an effect on the duration of licking bouts when animals consume solutions with a relatively high concentration of sucrose. The muscarinic antagonist scopolamine reduced bout durations, both systemically and intra-cortically. By contrast, the muscarinic agonist oxotremorine, the cholinesterase inhibitor physostigmine, the KCNQ channel blocker XE-991, and ghrelin all increased the durations of licking bouts when infused into the mPFC. Our findings suggest that cholinergic and ghrelinergic signaling in the mPFC, acting through KCNQ channels, regulates the expression of palatability.
Body Surveillance as a Moderator of the Relationship Between Fat Stereotypes and Body Dissatisfaction in Normal Weight Women

This study examined the moderating effect of body surveillance on the relationship between fat stereotyping and body dissatisfaction in normal weight women. Undergraduate participants (N = 301) completed online measures assessing explicit and implicit fat stereotyping, body surveillance, and body dissatisfaction. Neither explicit nor implicit fat stereotyping significantly predicted body dissatisfaction. Further, body surveillance did not moderate the relationship between either explicit or implicit fat stereotypes and body dissatisfaction. However, post-hoc analyses examining Caucasian participants (N = 224) found differing results. Specifically, body surveillance significantly moderated the relationship between explicit fat stereotyping and body dissatisfaction. Higher explicit fat stereotypes predicted greater body dissatisfaction in Caucasian women with lower body surveillance. Conversely, higher explicit fat stereotypes predicted lower body dissatisfaction in Caucasian women with higher body surveillance. These counterintuitive results suggest that endorsing fat stereotypes acts as a buffer against body dissatisfaction in Caucasian normal weight women with stronger body surveillance.
Reconciliation of continuous variable QKD using Gaussian post-selection and systematic Polar code

The transmission distance of continuous variable QKD (CV QKD) protocol based on Gaussian modulation has been quite limited by the low efficient reconciliation protocol. On the other hand, noiseless linear amplifier (NLA) have greatly enhanced the ability of CV QKD. In this paper, we propose a Gaussian post-selection method simulating NAL in CV QKD, followed by a reconciliation process based on systematic Polar code. We distill the reliable data through the post-selection filter as the raw key and then encode them with systematic polar code. The numerical simulation show that the secure transmission distance can be enlarged more than thirty kilometers while keeping the advantages of Gaussian security evidences. The key error rate can close to zero when signal-to-noise ratio (SNR) is near 3 dB.
An Experimental Implementation of Mobile IPv 6 on a Personal Digital

IPv6 is a new version of the Internet Protocol that was standardised by the Internet Engineering Task Force (IETF). Mobility support in IPv6 is presently being standardised by the IETF Mobile IP Working Group. IPv6 has been designed to overcome all the problems within IPv4 and to provide solutions for the next generation networks. Devices such as Personal Digital Assistants (PDAs) with IP support are widely used in mobile computing. In this paper, we describe our experimental implementation of Mobile IPv6 on an PDA. The basic functions of a Mobile Node (MN) such as movement detection and registration have been implemented in this experiment.
Interactive City Generation Methods ( sap _ 0172 )

In this sketch we present an interactive real-time city generation system. The aim of such a system is to apply procedural techniques to rapidly generate detailed city models suitable for use in graphics applications. Most commonly, the underlying road network for the city is generated first and is used as a basis for positioning buildings and other features. Existing work includes CityEngine [Parish and Müller 2001] which uses geo-statistical image maps and L-systems to generate road networks. Other researchers have employed agentbased simulation of land use [Lechner et al. 2004], or templates encapsulating common road patterns [Sun et al. 2002].
Chromosome aberration and sister chromatid exchange in workers of the iron and steel factory of Iskenderun, Turkey.

The aim of this study was to investigate, by using chromosome aberration (CA) and sister chromatid exchange (SCE) tests, whether or not the workers employed in the Iskenderun (Turkey) iron and steel factory have any genotoxic risk. The CA and the SCE were investigated in 48 males employed in a coke ovens unit and 8 males employed in a product side unit of the factory and in control groups. The frequency of CA was higher while the frequency of the SCE was not in all the smoker-nonsmoker workers than in smoker-nonsmoker control groups. In addition, there was no significant decrease in the RI, while the MI was significantly lower than in the controls.
Performance evaluation of LTE radio fingerprinting using field measurements

This paper evaluates positioning accuracy of radio fingerprinting algorithm in commercially deployed LTE (Long Term Evolution) network operating on 800 MHz, 1800 MHz and 2600 MHz frequency bands. Training database required for fingerprint positioning is constructed from field measurements that resemble LTE Release 10 Minimization of Drive Test (MDT) trace records. Performance is compared between LTE and LTE+WLAN grid-based RF fingerprint measurements utilizing partial fingerprint matching. Results indicate that partial fingerprints that consist of LTE and WLAN radio measurements decrease positioning errors at least by a factor of 3.5x while the percentage of discarded samples is kept low. This emphasizes the importance of having generic MDT functionality for automating the collection and correlation of radio measurements in heterogeneous LTE and WLAN networks.
WhatType of Process Underlies Options ? A Simple RobustTest

We develop a simple robust method to distinguish the presence of continuous and discontinuous components in the price of an asset underlying options. Our method examines the prices of at-the-moneyand out-of-the-money options as the option’s time-to-maturity approaches zero. We show that these prices converge to zero at speeds that depend upon whether the underlying asset price process is purely continuous, purely discontinuous, or a combination of both.We apply the method to S&P 500 index options and ¢nd the existence of both a continuous component and a jump component in the index. TO EFFECTIVELY PRICE OR HEDGE derivative securities, or to understand the behavior of ¢nancial asset prices in general, it is important to know if they are best modeled using a purely continuous process (PC), a pure jump process (PJ), or a combination of both (CJ). We develop a method to distinguish between these possibilities using options written on the asset in question. Speci¢cally, we examine the market prices of at-the-money (ATM) and out-of-the-money (OTM) options as the option’s maturity date approaches the valuation date. While the prices of all ATM and OTMoptions converge to zero as the time to maturity approaches zero, our theoretical work shows that the speed of convergence di¡ers across the three possibilities (PC, PJ, or CJ). We can thus identify the type of an asset price process by examining the convergence speeds of these option prices. The simplest approach for determining the type of process governing an asset price is to examine the time series of asset prices directly. However, the discretely sampled paths from the three types of processes look very similar unless the sampling frequency is extremelyhigh. Furthermore, increasing the sampling frequency introduces market microstructure e¡ects. Since our method does not examine the sample path of the underlying asset directly, it circumvents these di⁄culties. Our method is able to distinguish the type of process governing the price of an asset because di¡erent types of processes have dramatically di¡erent implications THE JOURNAL OF FINANCE VOL.

Distributed fair resource allocation in wireless multi-user multi-relay networks with heterogeneous rate constraints

This paper focuses on the problem of fair resource allocation in wireless multi-user multi-relay networks where both constant-rate users and variable-rate users exist. The problem is formulated as an optimization problem targeting at finding the Nash bargaining solution for the variable-rate users subject to a set of users' rate constraints and a set of relay power constraints. The formulated problem is proven to be a concave maximization problem, and the dual decomposition method is employed to find the optimal solution. Based on this method, a distributed algorithm is then proposed and its convergence is proved as well. Finally, simulations validate the convergence and fairness of the proposed algorithm.
A hybrid recommender system to predict online job offer performance

With the expansion of internet to advertise, the number of potential channels is increasing every day. In the Human Resource domain, recruiters have to choose between hundreds of job search web sites when they post a job offer on the internet. In order to save costs, assessing job board expected performance has become necessary. In this paper, three recommender systems providing job board performance estimation for a given job posting are introduced. This work refers principally to the new item problem, which is still a challenging topic in the literature. The ﬁrst system (PLS-R) is a content-based approach, while others are hybrid recommendation approaches. Estimation is made on item neighborhood according to a “naive” similarity or a supervised similarity measure. These predictive algorithms are compared through experiments on a real dataset. In this application, supervised similarity-based system overcomes the lacks of other approaches and outperforms them.
The Color of Emotions in Texts

Color affects every aspect of our lives. There has been a considerable interest in the psycholinguistic research area addressing the impact of color on emotions. In the experiments conducted by these studies, subjects have usually been asked to indicate their emotional responses to different colors. On the other side, sensing emotions in text by using NLP techniques has recently become a popular topic in computational linguistics. In this paper, we introduce a semantic similarity mechanism acquired from a large corpus of texts in order to check the similarity of colors and emotions. Then we investigate the correlation of our results with the outcomes of some psycholinguistic experiments. The conclusions are quite interesting. The correlation varies among different colors and globally we achieve very good results.
Opinion mining for emergency case risk analysis in spark based distributed system

The 2014 West African Ebola Outbreak rised from Sierra Leone, Guinea, and Liberia at December in 2013 has been reported to cause 21296 cases and 8429 deaths until now. Besides that, Typhoon Haiyan and Typhoon Hagupit are also the serious disaster accidents for emergency management in recnt years. In order to collect and analyze these accidents in more details, we need to design and adopt some new ideas and models. In this paper, we used Spark based Distributed mining system for online opinion data collecting and mining. We crawled related online social media data of Ebola from the most four favorite online social networks (including SINA, TENCENT) in China from June to November in 2014. By analyzing these attained social media data and airline data of GEM model, we found some interesting results. Furthermore, we collected the online social media data of Typhoon Haiyan and Hagupit before and after their landing. And we also showed analysis of combining social network data with geographical demonstration and Chinese citizen sentiment towards these disasters. As a result, we offered some suggestions to the government to handle opinion situation in these disasters.
Generalized Perona-Malik equation for image restoration

This article introduces generalizations of the Perona-Malik (1990) equation. An edge enhancing functional is proposed for direct edge enhancement. A number of super diffusion operators is introduced for fast and effective smoothing. Statistical information is utilized for robust edge-stopping. Numerical integration is conducted by using a previously developed quasi-interpolating wavelet method. Computer experiments indicate that the present algorithm is very efficient for edge-detecting and noise-removing.
Does a Cognitive Skills Training Program for Prisoners Affect Neurocognitive Functioning and Heart Rate Activity?

This study investigates changes in neurobiological characteristics after a cognitive skills program for prisoners. It was hypothesized that prisoners who completed a cognitive skills training program would show improved neurocognitive functioning and changes in heart rate (HR) activity. In addition, it was expected that neurobiological changes were related to behavioral improvement. Male adult prisoners were included in the study and divided into two groups: the “intervention group”—prisoners participating in a cognitive skills training program—and the “control group”—prisoners placed on a waitlist. Several neurocognitive skills and HR activity measures were assessed at pre- and posttest assessment. In addition, trainers, prison officers, and prisoners were requested to evaluate behavioral changes over time. Results did not confirm the hypotheses. The absence of both neurobiological and behavioral improvement is discussed in light of the measures used, the content and duration of the current intervention program, and the prison setting.
Influence of treated mud on free shrinkage and cracking tendency of self-compacting concrete equivalent mortars

The present work aims at studying the formulation and characterization of self-compacting concrete equivalent mortars, using calcined mud from the dredged sediments brought from the dam (Western Algeria) and fly ash from the Central Thermal EDF (France). Three SCCEM samples were prepared; a control mortar sample and two mortar samples containing 22% of mineral additions, with a ratio W/B = 0.47. The analysis of the experimental results obtained indicates that mortars comprising calcined mud develop greater compressive strengths than those containing fly ash. Regarding free shrinkage, mortar with calcined mud is characterized by an autogenous shrinkage similar to those of control and fly ash mortars. However, it is more sensitive to total shrinkage and drying as compared to the other mortars. Under the conditions of restrained shrinkage, control and calcined mud mortars are more sensitive to early cracking than mortar based on fly ash.
