Comparison of physical capacities between nonselected and selected elite male competitive surfers for the National Junior Team.

PURPOSE To determine whether a previously validated performance-testing protocol for competitive surfers is able to differentiate between Australian elite junior surfers selected (S) to the national team and those not selected (NS). METHODS Thirty-two elite male competitive junior surfers were divided into 2 groups (S=16, NS=16). Their age, height, body mass, sum of 7 skinfolds, and lean-body-mass ratio (mean±SD) were 16.17±1.26 y, 173.40±5.30 cm, 62.35±7.40 kg, 41.74±10.82 mm, 1.54±0.35 for the S athletes and 16.13±1.02 y, 170.56±6.6 cm, 61.46±10.10 kg, 49.25±13.04 mm, 1.31±0.30 for the NS athletes. Power (countermovement jump [CMJ]), strength (isometric midthigh pull), 15-m sprint paddling, and 400-m endurance paddling were measured. RESULTS There were significant (P≤.05) differences between the S and NS athletes for relative vertical-jump peak force (P=.01, d=0.9); CMJ height (P=.01, d=0.9); time to 5-, 10-, and 15-m sprint paddle; sprint paddle peak velocity (P=.03, d=0.8; PV); time to 400 m (P=.04, d=0.7); and endurance paddling velocity (P=.05, d=0.7). CONCLUSIONS All performance variables, particularly CMJ height; time to 5-, 10-, and 15-m sprint paddle; sprint paddle PV; time to 400 m; and endurance paddling velocity, can effectively discriminate between S and NS competitive surfers, and this may be important for athlete profiling and training-program design.
Ordres et géométrie plane : application au nombre de sauts

P etant un ordre, le nombre de sauts de p est le nombre minimum de comparaisons qu'il faut rajouter a p pour obtenir un ordre total. Ce parametre intervient dans certains problemes d'ordonnancement de taches, et son calcul est np-difficile en general. Par contre la complexite sur les ordres de dimension 2 (i. E. Les ordres qui sont l'intersection de 2 ordres totaux) est inconnue. Cette these presente des arguments de geometrie du plan qui permettent de resoudre certaines questions reliees au probleme du nombre de sauts sur les ordres de dimension 2. Nous montrons que ce probleme est equivalent au probleme suivant : etant donne un ensemble de rectangles ponderes du plan, quel est le poids maximum d'un sous-ensemble constitue de rectangles 2 a 2 disjoints ? grace a cette interpretation, nous montrons que le calcul est polynomial sur la classe des ordres de hauteur h (meme dans la version ponderee ou on attribue un poids a chaque couverture), alors que cette derniere version ponderee est np-difficile si la hauteur est quelconque, montrant que la complexite du probleme est dependante de la hauteur de l'ordre. D'autre part, nous nous interessons aux 2 ordres totaux dont un ordre p de dimension 2 est l'intersection, vis a vis du nombre de sauts, montrant entre autre que la somme des nombres de sauts produits par l'un et l'autre de ces ordres totaux ne depend que du graphe d'incomparabilite de p. Par ailleurs, nous nous interessons a certains problemes de representation des ordres de dimension 2 et 3. En montrant que les ordres de dimension 3 sont exactement les ordres d'inclusion de triangles isothetiques dans le plan, nous prouvons que la complexite de set packing passe de polynomial a np-complet lorsque le biparti d'adjacence sous-jacent passe de la dimension 2 a la dimension 3.
cDNA microarray reveals altered cytoskeletal gene expression in space‐flown leukemic T lymphocytes (Jurkat)

Cytoskeletal disruption and growth arrest consistently occur in space‐flown human acute leukemic T cells (Jurkat). Although the microtubules appear to reorganize during spaceflight, cells remain nonproliferative. To test the hypothesis that spaceflight alters cytoskeletal gene expression and may thus affect cytoskeletal function, we flew Jurkat cells on Space Transportation System (STS) 95 and compared RNA message by cDNA microarray in space‐flown vs. ground controls at 24 h (4,324 genes) and 48 h (>20,000 genes). Messages for 11 cytoskeleton‐related genes, including calponin, dynactin, tropomodulin, keratin 8, two myosins, an ankyrin EST, an actinlike protein, the cytoskeletal linker (plectin), and a centriole‐associated protein (C‐NAP1), were up‐regulated in space‐flown compared with ground control cells; gelsolin precursor was down‐regulated. Up‐regulation of plectin and C‐NAP1 message in both space‐flown cells and vibrated controls is a novel finding and implies their role in vibration damage repair. This first report of cDNA microarray screening of gene expression in space‐flown leukemic T cells also identifies differential expression of genes that regulate growth, metabolism, signal transduction, adhesion, transcription, apoptosis, and tumor suppression. Based on differential expression of cytoskeletal genes, we conclude that centriole‐centriole, membrane‐cytoskeletal, and cytoskeletal filament associations are altered in the orbital phase of spaceflight.
Improving handset antenna performance by wideband matching optimization

Matching circuits have not been paid much attention when studying antennas, although they have a significant effect on the performance of the designed antenna. This paper presents an easily adopted procedure to design wideband matching circuits for an arbitrary, frequency-dependent, real-life load impedance through optimization using a commercial circuit simulator. Several CCE antenna examples demonstrate the capability of the proposed method and emphasize the importance of the matching circuit design.
Reduction of low-frequency current ripples in fuel cell power conditioning systems using proportional-resonant control

The control methods used to reduce low-frequency current ripples in fuel cell power conditioning systems are discussed. The concept of minimized impedance design for the flow of harmonic currents in the energy storage branch is proposed since it can help improve the system dynamic response and harmonic absorption. The effects of different control strategies (including single voltage loop, single current loop and outer-voltage inner-current control loop) on the output impedance are evaluated and compared. Furthermore, proportional-resonant controllers are introduced to generate extremely low impedance for harmonic currents at specific frequencies. The theoretical analysis and control strategies are verified by simulation results.
DigiTouch

Input is a significant problem for wearable systems, particularly for head mounted virtual and augmented reality displays. Existing input techniques either lack expressive power or may not be socially acceptable. As an alternative, thumb-to-finger touches present a promising input mechanism that is subtle yet capable of complex interactions. We present DigiTouch, a reconfigurable glove-based input device that enables thumb-to-finger touch interaction by sensing continuous touch position and pressure. Our novel sensing technique improves the reliability of continuous touch tracking and estimating pressure on resistive fabric interfaces. We demonstrate DigiTouch’s utility by enabling a set of easily reachable and reconfigurable widgets such as buttons and sliders. Since DigiTouch senses continuous touch position, widget layouts can be customized according to user preferences and application needs. As an example of a real-world application of this reconfigurable input device, we examine a split-QWERTY keyboard layout mapped to the user’s fingers. We evaluate DigiTouch for text entry using a multi-session study. With our continuous sensing method, users reliably learned to type and achieved a mean typing speed of 16.0 words per minute at the end of ten 20-minute sessions, an improvement over similar wearable touch systems.
Recent Progress in Multifunctional Graphene Aerogels

Two dimensional (2D) graphene has become one of the most intensively explored carbon allotropes in materials science owing to attractive features like its outstanding physicochemical properties. In order to further realize practical applications, the fabrication of self-assembled 2D individual graphene sheets into 3D graphene aerogels (GAs) with special structures and novel functions, is now becoming essential. Moreover, GAs are ideal as supports for the introduction of nanoparticles, polymers, and functional materials to further enhance their applications in broad areas. GAs have light weight, large surface area, good compressibility, extensibility, and high electrical conductivity. They have been used as efficient electrodes for batteries, in supercapacitors, and in sensors and actuators. This critical review mainly addresses recent progress in the methods used for their syntheses, their properties, and applications for energy storage, and in sensors and actuators. Furthermore, to assist advanced research for practical applications of these emerging materials, the technical challenges are discussed, and future research directions are proposed.
The Effect of Exercise on Lactating Sow Performance

The objective of this study was to determine the effect of light, daily exercise on body condition score (BCS), soundness (SS), injury (IS), lesions (LS) weaning wt (WW), and back fat (BF) of lactating sows housed in farrowing crates. A total of 24 sows were used in four trials. Body weight (BW), BF, BCS, SS, IS, and LS were recorded at placement into the farrowing barn and again at weaning. A scale of 1 (poor) to 5 (excellent) was used for BCS, SS, and IS. Prior to farrowing, sows were grouped by BW and parity, and assigned to control (no exercise) or experimental (exercise) groups. After farrowing, the exercise sows (n=3) were removed from their crates for 1h/d for 17-19 d and encouraged to exercise; the control sows (n=3) remained in crates 24h/d. Saliva samples were collected 30 min prior to exercise and at 30 and 60 min after exercise for cortisol analysis. Piglets were weaned between 18 and 26 days of age. No difference was found between treatments for sow WW, BCS, IS, average daily feed intake, weaning litter wt, day 7 wt/d of age or piglet survivability. Exercise sows were leaner, sounder, and had more lesions at weaning than control sows (P<0.05). Exercise sows also had higher levels of salivary cortisol on average than control sows (P<0.05). These results indicate that increased movement of sows during lactation led to a decrease in back fat and an increase in soundness, with no affect on piglets.

Article history: Received: 01 March, 2018 Accepted: 28 March, 2018 Online: 25 April, 2018 E-Money mobile payments, also called digital money, are electronic payments, payment transactions using an Internet network integrated with NFC-enabled smartphones and prepaid cards. In Indonesia not only banks that issue e-money products, telecom operators from Telkomsel also issued an e-money product called T-cash. T-cash is a new innovation of electronic money presented by Telkomsel. The purpose of this study was to check the effect of responsiveness, smartness, perceived ease of use, perceived usefulness, social influence, and security against the intention to use T-cash. The data used in this study include primary and secondary data. Respondents in this study are users of T-cash products in Yogyakarta as many as 115 respondents. While the data were collected by using the questionnaire to then be analyzed using the amos analysis technique 22.0. The results of the analysis prove that two characteristics of technology, responsiveness and smartness have a significant effect on perceived usefulness. Ease of use has a significant effect on perceived usefulness. Ease of use, usefulness and security have a significant effect on intention to use. The higher the level of responsiveness, smartness, ease of use, perceived usefulness and security will also increase the use of T-cash social influence factors have no effect on intention to use.
The Level of Metabolic and Immunological Status of Newborn Calves under The Action of Timogen on The Body of Down-Calving Cows

The purpose of the current research was to determine possible effects of timogen on accumulation of immunoglobulins and other immunogenic factors in the mammary gland of cows before calving, their release with colostrum, as well as the impact of these factors on the level of metabolic and immunological status of newborn calves after feeding them with colostrum. The data are obtained in the experiments conducted at “Arsenyevskoye” (Kaluga region) and “Mir” (Dalnekonstantinovsky district of Nizhny Novgorod region) farming enterprises. The experiment is done in the spring and summer periods of 2015 testing down-calving cows and their new-born calves. The experiment was conducted in 2 stages. The studying objects of the 1st stage were 8 down-calving cows of black-motley breed selected based on the principle of analogs, which were divided into control and experimental groups. Cows from the experimental group were exposed to intramuscular injection of timogen at a dose of 1.2 mg 3-6 days before calving. Control animals were injected subcutaneously with sodium chloride physiological solution according to the same pattern. Blood for research was taken from newborn calves one day and ten days after birth. Twenty-four hours after the start of feeding newborn calves with colostrum, elevated levels of immunoglobulins, total protein and hemoglobin were observed in their blood as compared to the calves from the control group. These differences persisted during 10 days after birth. The second stage of the experiment was conducted in the farming enterprise “Mir” of the Dalnekonstantinovsky district of Nizhny Novgorod region. The studies were performed according to the same scheme. Twelve down-calving cows were selected on the basis of the principle of analogs. Besides, blood analysis was conducted using additional morphological and immunological methods. Twenty-four hours after birth and feeding with colostrum, calves born from experimental cows, showed significantly increased number of erythrocytes and leukocytes, mainly at the cost of lymphocytes, as well as a higher level of total protein and its fractions, especially βand γ-globulins, and increased bactericidal and lysozyme activity of blood serum.
Nomenclature of systemic vasculitides. Proposal of an international consensus conference.

The following are some of the conclusions and proposals made at the Chapel Hill Consensus Conference on the Nomenclature of Systemic Vasculitis. 1. Although not a prerequisite component of the definitions, patient age is recognized as a useful discriminator between Takayasu arteritis and giant cell (temporal) arteritis. 2. The name "polyarteritis nodosa," or alternatively, the name "classic polyarteritis nodosa," is restricted to disease in which there is arteritis in medium-sized and small arteries without involvement of smaller vessels. Therefore, patients with vasculitis affecting arterioles, venules, or capillaries, including glomerular capillaries (i.e., with glomerulonephritis), are excluded from this diagnostic category. 3. The name "Wegener's granulomatosis" is restricted to patients with granulomatous inflammation. Patients with exclusively nongranulomatous small vessel vasculitis involving the upper or lower respiratory tract (e.g., alveolar capillaritis) fall into the category of microscopic polyangiitis (microscopic polyarteritis). 4. The term "hypersensitivity vasculitis" is not used. Most patients who would have been given this diagnosis fall into the category of microscopic polyangiitis (microscopic polyarteritis) or cutaneous leukocytoclastic angiitis. 5. The name "microscopic polyangiitis," or alternatively, "microscopic polyarteritis," connotes pauci-immune (i.e., few or no immune deposits) necrotizing vasculitis affecting small vessels, with or without involvement of medium-sized arteries. Cryoglobulinemic vasculitis, Henoch-Schönlein purpura, and other forms of immune complex-mediated small vessel vasculitis must be ruled out to make this diagnosis. 6. The name "cutaneous leukocytoclastic angiitis" is restricted to vasculitis in the skin without involvement of vessels in any other organ. 7. Mucocutaneous lymph node syndrome must be present to make a diagnosis of Kawasaki disease. (ABSTRACT TRUNCATED AT 250 WORDS)
The effect of prophylactic clonidine on postoperative shivering

The primary goal of this study was to assess the influence of clonidine administered after induction on postoperative shivering after elective peripheral surgery. The effect of clonidine on intra‐operative haemodynamics (blood pressure and heart rate) during the first 30 min after induction and on the postoperative sedation of the patient was also investigated. Two hundred and eighty male ASA 1 and 2 patients, undergoing elective peripheral surgery were randomly administered either placebo or clonidine 2 μg. kg‐1 intravenously over 10 min after induction of anaesthesia. Clonidine was found to reduce the total incidence (p = 0.024), the severity (p = 0.005) and the duration (p= 0.01) of postoperative shivering. Clonidine did not increase postoperative sedation or diminish overall consciousness. We conclude that administration of clonidine 2 μg. kg‐1 intravenously after induction of anaesthesia is safe and reduces postoperative shivering in this group of patients.
A bit reconfigurable attenuator based on MEMS switch and TAN resistor

In this paper, a novel design of a bit reconfigurable attenuator based on MEMS switch and TaN resistor is presented. The overall size of the new design is smaller than that of the traditional RF power attenuator. The proposed attenuator was modeled and simulated using commercial software and fabricated using surface micromachining process. The results of the tests indicate this new MEMS attenuator has very good performance in the application frequency range of DC-20GHz. The pull-down voltage of the switch is only 40 V. In the frequency range of DC to 20 GHz, when the transmission path is turned on, its insertion loss is less than -3.8 dB and the return loss is more than -10.8dB. When the attenuation path is turned on, its measured attenuation is at 11.3±2.1 dB and the return loss is more than -19.8dB@DC-20GHz.
Long-term trends in Medicare payments in the last year of life.

OBJECTIVE To update research on Medicare payments in the last year of life. DATA SOURCES Continuous Medicare History Sample, containing annual summaries of claims data on a 5 percent sample from 1978 to 2006. STUDY DESIGN Analyses were based on elderly beneficiaries in fee for service. For each year, Medicare payments were assigned either to decedents (persons in their last year) or to survivors (all others). RESULTS The share of Medicare payments going to persons in their last year of life declined slightly from 28.3 percent in 1978 to 25.1 percent in 2006. After adjustment for age, sex, and death rates, there was no significant trend. CONCLUSIONS Despite changes in the delivery of medical care over the last generation, the share of Medicare expenditures going to beneficiaries in their last year has not changed substantially.
Multiple roles of the candidate oncogene ZNF217 in ovarian epithelial neoplastic progression

The transcription factor ZNF217 is often amplified in ovarian cancer, but its role in neoplastic progression is unknown. We introduced ZNF217‐HA by adenoviral and retroviral infection into normal human ovarian surface epithelial cells (OSE), i.e., the source of ovarian cancer, and into SV40 Tag/tag expressing, p53/pRB‐deficient OSE with extended but finite life spans (IOSE). In OSE, ZNF217‐HA reduced cell–substratum adhesion and accelerated loss of senescent cells, but caused no obvious proneoplastic changes. In contrast, ZNF217‐HA transduction into IOSE yielded two permanent lines, I‐80RZ and I‐144RZ, which exhibited telomerase activity, stable telomere lengths, anchorage independence and reduced serum dependence, but were not tumorigenic in SCID mice. This immortalization required short‐term EGF treatment near the time of crisis. The permanent lines were EGF‐independent, but ZNF217‐dependent since siRNA to ZNF217 inhibited anchorage independence and arrested growth. Array CGH revealed genomic changes resembling those of ovarian carcinomas, such as amplicons at 3q and 20q, and deletions at 4q and 18, associated with underexpressed annexin A10, N‐cadherin, desmocollin 3 and PAI‐2, which have been reported as tumor suppressors. The lines overexpressed EEF1A2, SMARA3 and STAT1 and underexpressed other oncogenes, tumor suppressors and extracellular matrix/adhesion genes. The results implicate ZNF217 as an ovarian oncogene, which is detrimental to senescing normal OSE cells but contributes to neoplastic progression in OSE with inactivated p53/RB. The resemblance of the genomic changes in the ZNF217‐overexpressing lines to ovarian carcinomas provides a unique model to investigate interrelationships between these changes and ovarian neoplastic phenotypes. © 2007 Wiley‐Liss, Inc.
Determinants of prostate cancer-specific survival after radiation therapy for patients with clinically localized prostate cancer.

PURPOSE Identifying pretreatment and posttreatment predictors of time to prostate cancer-specific death (PCSD) after external-beam radiation therapy (RT) was the subject of this study. PATIENTS AND METHODS A Cox regression analysis was used to evaluate the ability of the pretreatment risk group to predict time to PCSD for 381 patients who underwent RT for clinically localized prostate cancer. Posttreatment factors analyzed for the 94 patients who experienced prostate-specific antigen (PSA) failure included the time to PSA failure, the posttreatment PSA doubling time (DT), and the timing of salvage hormonal therapy. RESULTS Despite the median age of 73 years at diagnosis, 45% of patients with high-risk disease were estimated to die from prostate cancer within 10 years after RT compared with 0% (P =.004) and 6% (P =.05) for patients with low- or intermediate-risk disease, respectively. Predictors of time to PCSD after PSA failure included PSA DT (P =.01) and delayed use of hormonal therapy (P <or=.002). Nearly identical estimates of PCSD and all-cause death after PSA failure were noted for patients with a short PSA DT (ie, <or= 12 months). CONCLUSION Prostate cancer was a major cause of death during the first decade after RT for patients with clinically localized but high-risk disease, and the cause of death for patients with a short PSA DT after RT was nearly always prostate cancer. These data provide evidence to propose the hypothesis that a short posttreatment PSA DT may serve as a possible surrogate for PCSD. Prospective validation is needed.
