Sleep Deprivation: Effect on Mental Task Performance of Military Cadets

In modern society, prolonged wakefulness is a common phenomenon. Amongst students of the military, this is a frequent occurrence. There is a broad consensus that insufficient sleep leads to general slowing of response and increased variability in performance. Attention, long-term memory and decision-making have also been found to be influenced by sleep deprivation. Studies on effects on more demanding cognitive functions and among some essential subpopulations are required.This study was aimed at comparing the effects of varied levels of sleep deprivation on mental task performance of military students. It was hypothesized that deprivation (acute or chronic) would impair performance in mental tasks. A series of mental tasks were administered to military students (n= 76) of the Nigerian Defence Academy (NDA). Results showed sleep deprivation adversely affected mental task performance in the population but no significant difference was found between acute or chronic sleep deprivations on performance on a mental task.
Impact of treatment of sleep apnoea on left ventricular function in congestive heart failure

4Whether ‚ adrenergic blockers oVer a true survival benefit is currently debated. 56 Clearly, other therapeutic modalities need to be developed. This brief review discusses the role of sleep apnoea and its reversal with continuous positive airway pressure (CPAP) in patients with CHF. Discussion will focus initially upon the rationale for CPAP in acute unstable and chronic stable CHF. Thereafter, the influence of long term treatments of sleep apnoea (CPAP and other treatments) on cardiac function in patients with chronic CHF will be discussed. As early as 1936 positive airway pressure was used to treat acute cardiogenic pulmonary oedema. 7 Since then, many clinicians have reported improvements in cardiopulmonary physiology such as arterial blood gas tensions and work of breathing in patients with acute cardiogenic pulmonary oedema who were mechanically ventilated with positive end expiratory pressure (PEEP). 8 Similar reports were observed in patients with cardiogenic pulmonary oedema breathing spontaneously with CPAP
9-2011 Multi-Strategy Approaches to Active Learning for Statistical Machine Translation

This paper investigates active learning to improve statistical machine translation (SMT) for low-resource language pairs, i.e., when there is very little pre-existing parallel text. Since generating additional parallel text to train SMT may be costly, active sampling selects the sentences from a monolingual corpus which if translated would have maximal positive impact in training SMT models. We investigate different strategies such as density and diversity preferences as well as multistrategy methods such as modified version of DUAL and our new ensemble approach GraDUAL. These result in significant BLEU-score improvements over strong baselines when parallel training data is scarce.
Modeling the magnetospheres of luminous stars: Interactions between supersonic radiation-driven winds and stellar magnetic fields

Hot, luminous stars (spectral types O and B) lack the hydrogen recombination convection zones that drive magnetic dynamo generation in the sun and other cool stars. Nonetheless, observed rotational modulation of spectral lines formed in the strong, radiatively driven winds of hot stars suggests magnetic perturbations analogous to those that induce “co-rotating interaction regions” in the solar wind. Indeed, recent advances in spectropolarimetric techniques have now led to direct detection of moderate to strong (100–10 000G), tilted dipole magnetic fields in several hot stars. Using a combination of analytic and numerical magnetohydrodynamic models, this paper focuses on the role of such magnetic fields in channeling, and sometimes confining, the radiatively driven mass outflows from such stars. The results show how “magnetically confined wind shocks” can explain the moderately hard x-ray emission seen from the O7V star Theta-1 Ori C, and how the trapping of material in a “rigidly rotating magnetosphere” c.

A Survey of Analogs to Weak Mg II Absorbers in the Present

We present the results of a survey of the analogs of weak Mg II absorbers [rest-frame equivalent width Wr(2796) < 0.3 Å] at 0 < z < 0.3. Our sample consisted of 25 HST STIS echelle quasar spectra (R = 45,000), which covered Si II λ1260 and C II λ1335 over this redshift range. Using those similar transitions as tracers of Mg II facilitates a much larger survey, covering a redshift path length of g(z) = 5.3 for an equivalent width limit of Mg II corresponding to Wr(2796) > 0.02 Å, with 30% completeness for the weakest lines. Correcting for incompleteness, we find the number of weak Mg II absorber analogs with 0.02 Å < Wr(2796) < 0.3 Å to be dN/dz = 1.00 ± 0.20 for 0 < z < 0.3. This compares to a value of dN/dz = 1.74 ± 0.10 found by Churchill et al. for the higher redshift range, 0.4 < z < 1.4, and is consistent with cosmological evolution of the population. We consider the expected effect on observability of weak Mg II absorbers of the decreasing intensity of the extragalactic background radiation field from z ~ 1 to ~0. Assuming that all the objects that produce absorption at z ~ 1 are stable on a cosmological timescale and that no new objects are created, we would expect dN/dz ~ 2-3 at z ~ 0. About 30%-50% of this z ~ 0 population would be descendants of the parsec-scale structures that produce single-cloud, weak Mg II absorbers at z ~ 1. The other 50%-70% would be lower density, kiloparsec-scale structures that produce C IV absorption, but not detectable low-ionization absorption, at z ~ 1. We conclude that at least one, and perhaps some fraction of both, of these populations has evolved away since z ~ 1, in order to match the z ~ 0 value of dN/dz measured in our survey. This would follow naturally for a population of transient structures whose generation is related to star-forming processes, whose rate has decreased since z ~ 1.
ESAIM: Control, Optimisation and Calculus of Variations

We consider a 1-D tank containing an inviscid incompressible irrotational fluid. The tank is subject to the control which consists of horizontal moves. We assume that the motion of the fluid is well-described by the Saint–Venant equations (also called the shallow water equations). We prove the local controllability of this nonlinear control system around any steady state. As a corollary we get that one can move from any steady state to any other steady state.

Oligomerization of ZFYVE27 (Protrudin) Is Necessary to Promote Neurite Extension

ZFYVE27 (Protrudin) was originally identified as an interacting partner of spastin, which is most frequently mutated in hereditary spastic paraplegia. ZFYVE27 is a novel member of FYVE family, which is implicated in the formation of neurite extensions by promoting directional membrane trafficking in neurons. Now, through a yeast two-hybrid screen, we have identified that ZFYVE27 interacts with itself and the core interaction region resides within the third hydrophobic region (HR3) of the protein. We confirmed the ZFYVE27's self-interaction in the mammalian cells by co-immunoprecipitation and co-localization studies. To decipher the oligomeric nature of ZFYVE27, we performed sucrose gradient centrifugation and showed that ZFYVE27 oligomerizes into dimer/tetramer forms. Sub-cellular fractionation and Triton X-114 membrane phase separation analysis indicated that ZFYVE27 is a peripheral membrane protein. Furthermore, ZFYVE27 also binds to phosphatidylinositol 3-phosphate lipid moiety. Interestingly, cells expressing ZFYVE27ΔHR3 failed to produce protrusions instead caused swelling of cell soma. When ZFYVE27ΔHR3 was co-expressed with wild-type ZFYVE27 (ZFYVE27WT), it exerted a dominant negative effect on ZFYVE27WT as the cells co-expressing both proteins were also unable to induce protrusions and showed cytoplasmic swelling. Altogether, it is evident that a functionally active form of oligomer is crucial for ZFYVE27 ability to promote neurite extensions.
Fibers in Cultured Human Endothelial Cells with Concomitant Loss of Focal Adhesions and Actin Stress Endostatin-induced Modulation of Plasminogen Activation Updated Version Cited Articles Citing Articles E-mail Alerts Endostatin-induced Modulation of Plasminogen Activation with Concomitant Loss of F

Endostatin, a M r 20,000 fragment of collagen XVIII, is able to inhibit angiogenesis and induce apoptosis in endothelial cells in vivo. We analyzed the effects of recombinant endostatin on human microvascular endothelial cells, focusing on pericellular plasminogen activation and its targeting by the focal adhesion-associated cytoskeletal structures. Analysis of the pro-teolytic plasminogen activator system revealed that endostatin modulates the distribution of soluble and cell surface-associated urokinase-type plas-minogen activator (uPA) and plasminogen activator inhibitor, type 1 (PAI-1). Casein zymographic and immunoprecipitation analyses indicated that endostatin exerts its effects by decreasing the levels of soluble uPA and PAI-1 and their complexes in a dose-dependent manner. Immunoflu-orescence analysis of cell surface-associated uPA indicated that endostatin treatment caused the redistribution of receptor-bound uPA from focal contacts, resulting in diffuse cell surface staining. In accordance with this observation, immunofluorescence staining of the urokinase receptor revealed that endostatin treatment removed uPAR from focal adhesions. Accordingly, endostatin caused a rapid disassembly of focal adhesions as observed by immunofluorescence analysis of the focal adhesion proteins vinculin and paxillin. A prominent change in the cytoskeletal architecture was observed as the actin stress fiber network was dissociated in response to endostatin treatment. The effect of focal adhesion disassembly was reversible, persisting from 1 h up to 6 h. Our results suggest that the antiangiogenic activity of endostatin involves the modulation of focal adhesions and actin stress fibers and the down-regulation of the urokinase plasminogen activator system.
Movement analysis of grasp-type underwater microrobot

In this paper, a novel biomimetic walking grasp-type underwater microrobot, which looked like a crab with eight legs, was presented at first. The intermediate four legs are made of one piece of ICPF (Ionic Conducting Polymer Film) and two pieces of plastic flake used for grasping and releasing objects; the other four legs which are used for walking are made up of two pieces of ICPFs. The structure and motion mechanism of the microrobot are given in the paper. And a new method to grasp object through the intermediate four legs of the microrobot is proposed. The dynamic analysis of the grasp-leg during the process of the grasping is also proposed. The movement of the grasp-leg under different control signals by changing the frequency and amplitude of the input single is discussed. At last, the experiments of grasping movement of the microrobot are carried out.
Towards a fair comparison between name disambiguation approaches

Searching for information about people in search engines is a common and straightforward task that is often hampered by name ambiguities. While users are interested in information about a single person, results pages usually comprise many persons with the same name. There are several approaches to tackle personal name disambiguation; however, it is still a challenge to understand the impact of each approach alone. In this paper, we present a plugin-based framework that aims to compare and to identify the most promising approaches for name disambiguation. This framework enabled us to merge different approaches to find good combinations for this task and to compare state-of-the-art solutions using a common dataset. Preliminary results support the greater impact of biographical information to aid in clustering, the use of comprehensive texts instead of only metadata and TF-IDF instead of more complex approaches.
Hospital Participatory Information System - An innovative electronic participatory platform for improved hospital operation and superior hospital health services provisioning

Public Hospitals are large and complex organizations targeted in providing Health Services to citizens. Due to the complexity, multidisciplinary competences such as budgetary or techno-economical issues they incorporate and complex cases they have to deal with, the services they provide are usually deprived in terms of quality. In this paper we propose a Hospital Participatory Information System that will be used to bring together all Hospital stakeholders (e.g medical personnel, patients and even visitors) and will promote innovation and idea creation, aiming in improving both health services offered to patients, but also intra-hospital operational issues e.g related to the daily job of (non)-medical personnel.
Modeling GARCH processes in Panel Data : Theory , Simulations and Examples

In this paper we propose and implement a methodology for testing and estimating GARCH effects in a panel data context. We propose simple tests based on OLS and LSDV residuals to determine whether GARCH effects exist and to test for individual effects in the conditional variance. Estimation of the model is based on direct maximization of the log-likelihood function by numerical methods. Monte Carlo studies are conducted in order to evaluate the performance of this MLE estimator for various relevant designs. We also present two empirical applications. We investigate whether investment in a panel of five large U.S. manufacturing firms, or inflation in a panel of seven Latin American countries exhibit GARCH effects. Our panel GARCH estimator satisfactorily captures the significant conditional heteroskedasticity in the data in both cases.

Gait is one of fundamental motion in human daily life. Therefore, malfunction for gait motion strongly affects the human health. Gait analysis helps to prevent the human health from the malfunction gait. This study developed a sole pressure measurement system which can provide sole pressure and pose of sole in gait motion. In the experiment, the system was applied for normal human to examine several daily motions. Consequently, the system could provide sole pressure and pose in gait motion.
Discrete Passive Filtering of Singular Systems with Time-varying Delay

This paper considers the problem of discrete passive filter design method for singular systems with interval time-varying delay. A bounded real lemma (BRL) for discrete passivity with a dissipation of discretetime delayed singular systems by a Lyapunov function is derived. A delay-dependent discrete passive filter design method is proposed by linear matrix inequality (LMI) approach on the basis of the derived BRL.

We here describe FTM, a system deployed at the University of Stuttgart for the uniform, secure, interactive Access, Transfer, and Management of informational resources in a network or Grid consisting of facilities at distributed Virtual Organizations. The extension of this system to support computational workflows is also reported Keywords—file transfer, Grid environments.
A secure and privacy protection digital goods trading scheme in cloud computing

In a cloud computing environment, a seller can store her/his digital goods in a cloud server, and then sell them when a buyer needs. In order to protect the digital content's privacy, the seller should store her/his digital goods in an encrypted form before being stored in a cloud. However, the method of directly encrypting digital goods maybe not work well if buyers and sellers trade with the digital goods in this environment. The reason is that the cloud server could not decide which digital goods contain certain keywords requested by a buyer if the meta data of the encrypted digital goods is not searchable. In this paper, we propose a secure digital goods trading scheme in the cloud computing. Our scheme can efficiently protect keywords privacy for buyers, and make the cloud server to search the keywords on the encrypted digital content to protect the privacy of sellers' digital content. We also provide an efficient trading method to let buyers and sellers trade with the matched digital goods in a cloud.
Nanophotonics Based on Semiconductor-Photonic Crystal/Quantum Dot and Metal-/Semiconductor-Plasmonics

This paper reviews our recent activities on nanophotonics based on a photonic crystal (PC)/quantum dot (QD)-combined structure for an all-optical device and a metal/semiconductor composite structure using surface plasmon (SP) and negative refractive index material (NIM). The former structure contributes to an ultrafast signal processing component by virtue of new PC design and QD selective-area-growth technologies, while the latter provides a new RGB color filter with a high precision and optical beam-steering device with a wide steering angle.
Main Benefits and Applicability of Plant Extracts in Skin Care Products

Natural ingredients have been used for centuries for skin care purposes. Nowadays, they are becoming more prevalent in formulations, due to consumers’ concerns about synthetic ingredients/chemical substances. The main benefits reported for plant extracts, used in skin care, include antioxidant and antimicrobial activities and tyrosinase inhibition effect. In this review, some examples of plants from Portuguese flora, whose extracts have shown good properties for skin care are presented. However, despite the known properties of plant extracts, few studies reported the development of formulations with them. More work in this field can be accomplished to meet consumer demand.
Prediction of Reservoir-induced Earthquake Based on Fuzzy Theory

With more and more reservoirs have been and are being built all over the world, reservoir-induced earthquake has received a great deal of attention from geoscientists mainly because of its potential to damage constructions and to cause human losses. Based on the previous researches on the environmental conditions of reservoir-induced earthquake, a criteria hierarchy model has been constructed. We give the environmental condition an uncertain description by applying weight in this theory, which shows that the different factor plays different role in risk assessment. Taking one candidate assessment unit into consideration, the risk class through fuzzy theory is obtained. Based on the original mechanism, a fuzzy mathematical prediction model of three-gorge reservoir in China has been created. It is concluded that compared with other mathematical prediction models, the reservoirinduced earthquake prediction model based on the fuzzy theory can analyze data with fuzzy processing and therefore possesses advantages of high prediction accuracy.
An Empirical Study on Summarizing Multiple Texts of Japanese Newspaper Articles

In this paper, we attempt to summarize multiple Japanese articles into one document with non-parsing approach. We mention deletions of the overlapped part among the input texts. Japanese grammar is considerably free in word order and allows high abridgement. This research aims at coping with these phenomena. This paper focuses on the following three points to sum up : same clauses, noun modi ers, and change in wording. We have implemented a prototype system of summarization.
Design and Rationale of the PRAGUE‐12 Trial: A Large, Prospective, Randomized, Multicenter Trial That Compares Cardiac Surgery With Left Atrial Surgical Ablation With Cardiac Surgery Without Ablation in Patients With Coronary and/or Valvular Heart Disease Plus Atrial Fibrillation

Surgical ablation procedure can restore sinus rhythm (SR) in patients with atrial fibrillation (AF) undergoing cardiac surgery. However, it is not known whether it has any impact on clinical outcomes. There is a need for a randomized trial with long‐term follow‐up to study the outcome of surgical ablation in patients with coronary and/or valve disease and AF. Patients are prospectively enrolled and randomized either to group A (cardiac surgery with left atrial ablation) or group B (cardiac surgery alone). The primary efficacy outcome is the SR presence (without any AF episode) during a 24‐hour electrocardiogram after 1 year. The primary safety outcome is the combined end point of death, myocardial infarction, stroke, and renal failure at 30 days. Long‐term outcomes are a composite of total mortality, stroke, bleeding, and heart failure at 1 and 5 years. We finished the enrollment with a total of 224 patients from 3 centers in 2 countries in December 2011. Currently, the incomplete 1‐year data are available, and the patients who enrolled first will have their 5‐year visits shortly. PRAGUE‐12 is the largest study to be conducted so far comparing cardiac surgery with surgical ablation of AF to cardiac surgery without ablation in an unselected population of patients who are operated on for coronary and/or valve disease. Its long‐term results will lead to a better recognition of ablation's potential clinical benefits.
Choosing Our Words: Retrieval and Selection Processes Recruit Shared Neural Substrates in Left Ventrolateral Prefrontal Cortex

When we speak, we constantly retrieve and select words for production in the face of multiple possible alternatives. Our ability to respond in such underdetermined situations is supported by left ventrolateral prefrontal cortical (VLPFC) regions, but there is active debate about whether these regions support (1) selection between competing alternatives, (2) controlled retrieval from semantic memory, or (3) selection and controlled retrieval in distinct subregions of VLPFC (selection in mid-VLPFC and controlled retrieval in anterior VLPFC). Each of these theories has been supported by some prior evidence but challenged by other findings, leaving the debate unresolved. We propose that these discrepancies in the previous literature reflect problems in the way that selection and controlled retrieval processes have been operationalized and measured. Using improved measures, we find that shared neural substrates in left VLPFC support both selection and controlled retrieval, with no dissociation between mid and anterior regions. Moreover, selection and retrieval demands interact in left VLPFC, such that selection effects are greatest when retrieval demands are low, consistent with prior behavioral findings. These findings enable a synthesis and reinterpretation of prior evidence and suggest that the ability to respond in underdetermined situations is affected by both selection and retrieval mechanisms for verbal material subserved by left VLPFC, and these processes interact in meaningful ways.
