Authors: Sim Wai S. , Tan Saw C. , Yusoff Zulfadzli 
Published: July 2016

Abstract
A stimulated Raman scattering (SRS)-aware routing and wavelength assignment (RWA) scheme, called assign minimum interference and shortest algorithm, is proposed to minimize the effect of SRS in network. The design parameter, the number of interference of routes in the proposed algorithm is investigated to analyze its capabilities of influence the network performance. The various setting of the parameter is tested in 15-nodes Mesh and 14-nodes National Science Foundation networks for analysis in order to provide useful guidelines for designing effective SRS-aware RWA scheme. The ultimate objective is to define the necessary and sufficient rules that must be followed in the proposed algorithm by identifying the necessary RWA parameters in order to minimize the effect of SRS in optical networks. The result shows that the smaller the number of interference of routes, the lower the blocking probability in the mentioned topologies.

Abstract

Background:
Idiopathic intracranial hypertension (IIH) is one of the most important and rare complications of obesity. Prevalence of IIH in childhood obesity is not known. The purpose of this study was to determine the prevalence of IIH in obese children and adolescents and to investigate the relevant factors.

Methods:
In this study, 1058 obese children and adolescents between 2 and 18 years of age were included. Funduscopic examination was conducted for all subjects. In cases with papilledema, increase in intracranial pressure was clarified by measuring CSF pressure with a lumbar puncture. Other causes of IIH were ruled out with clinical, laboratory tests and imaging techniques.

Results:
Idiopathic intracranial hypertension was diagnosed in 14 subjects (1.32%). Rates of headache and systemic hypertension in subjects with IIH was determined to be 78.6% and 28.6%, respectively. Morning cortisol, fasting insulin and HOMA-IR values were found to be significantly higher in this cases (p<0.05).

Conclusions:
In childhood obesity, IIH should be kept in mind as a serious complication. Funduscopic examination is an easy method that suggests IIH. In particular, obese children with systemic hypertension and refractory headache should be considered for IIH.

Published: July 2016

Abstract
By using the critical point method, some new criteria are obtained for the existence and multiplicity of homoclinic solutions to a 2nth-order nonlinear difference equation. The proof is based on the Mountain Pass Lemma in combination with periodic approximations. Our results extend and improve some known ones.

Authors: Anh Cung The , Thanh Nguyen Van 
Published: July 2016

AbstractWe investigate the effect of Ito noise on the stability of stationary solutions to a class of semilinear degenerate parabolic equations with the nonlinearity satisfying an arbitrary polynomial growth condition. We will show that an Ito noise of sufficient intensity will stabilize the unstable stationary solution.
Performance Enhancement of One and Two-Shaft Industrial Turboshaft Engines Topped With Wave Rotors
Authors: Fatsis Antonios 
Published: July 2016

Abstract
Wave rotors are rotating equipment designed to exchange energy between high and low enthalpy fluids by means of unsteady pressure waves. In turbomachinery, they can be used as topping devices to gas turbines aiming to improve performance. The integration of a wave rotor into a ground power unit is far more attractive than into an aeronautical application, since it is not accompanied by any inconvenience concerning the over-weight and extra dimensioning. Two are the most common types of ground industrial gas turbines: The one-shaft and the two-shaft engines. Cycle analysis for both types of gas turbine engines topped with a four-port wave rotor is calculated and their performance is compared to the performance of the baseline engine accordingly. It is concluded that important benefits are obtained in terms of specific work and specific fuel consumption, especially compared to baseline engines with low compressor pressure ratio and low turbine inlet temperature.

Abstract
South, MA, Layne, AS, Stuart, CA, Triplett, NT, Ramsey, MW, Howell, ME, Sands, WA, Mizuguchi, S, Hornsby, WG, Kavanaugh, AA, and Stone, MH. Effects of short-term free-weight and semiblock periodization resistance training on metabolic syndrome. J Strength Cond Res 30(10): 2682–2696, 2016—The effects of short-term resistance training on performance and health variables associated with prolonged sedentary lifestyle and metabolic syndrome (MS) were investigated. Resistance training may alter a number of health-related, physiological, and performance variables. As a result, resistance training can be used as a valuable tool in ameliorating the effects of a sedentary lifestyle including those associated with MS. Nineteen previously sedentary subjects (10 with MS and 9 with nonmetabolic syndrome [NMS]) underwent 8 weeks of supervised resistance training. Maximum strength was measured using an isometric midthigh pull and resulting force-time curve. Vertical jump height (JH) and power were measured using a force plate. The muscle cross-sectional area (CSA) and type were examined using muscle biopsy and standard analysis techniques. Aerobic power was measured on a cycle ergometer using a ParvoMedics 2400 Metabolic system. Endurance was measured as time to exhaustion on a cycle ergometer. After training, maximum isometric strength, JH, jump power, and V̇o
2peak increased by approximately 10% (or more) in both the metabolic and NMS groups (both male and female subjects). Over 8 weeks of training, body mass did not change statistically, but percent body fat decreased in subjects with the MS and in women, and lean body mass increased in all groups (p ≤ 0.05). Few alterations were noted in the fiber type. Men had larger CSAs compared those of with women, and there was a fiber-specific trend toward hypertrophy over time. In summary, 8 weeks of semiblock free-weight resistance training improved several performance variables and some cardiovascular factors associated with MS.

Abstract
Ramos-Campo, DJ, Rubio-Arias, JÁ, Freitas, TT, Camacho, A, Jiménez-Diaz, JF, and Alcaraz, PE. Acute physiological and performance responses to high-intensity resistance circuit training in hypoxic and normoxic conditions. J Strength Cond Res 31(4): 1040–1047, 2017—The aim of this study was to analyze physical performance and physiological variables during high-intensity resistance circuit training (HRC) with the addition of 2 levels (moderate and high) of systemic hypoxia. Twelve resistance-trained young male subjects participated in the study. After a 6 repetition maximum testing session, participants performed 3 randomized trials of HRC: normoxia (NORM: fraction of inspired oxygen [FiO2] = 0.21; ∼0 m altitude), moderate hypoxia (MH: FiO2 = 0.16; ∼2.100 m altitude), or high hypoxia (HH: FiO2 = 0.13; ∼3.800 m altitude), as controlled by a hypoxic generator. Bench press force, heart rate and heart rate variability, rating of perceived exertion, resting metabolic rate, energy cost, and countermovement jump were assessed in each session. Heart rate variability in HH was significantly lower (standard deviation of all normal NN intervals [intervals between two “normal” beats] = 111.9 vs. 86.7 milliseconds; standard deviation of the difference between consecutive NN intervals = 19.5 vs. 17.0 milliseconds; p ≤ 0.05) in comparison with NORM. There were significant differences in rating of perceived exertion between NORM and HH (11.6 vs. 13.8 points). Peak and mean force on the bench press were significantly lower (p ≤ 0.05) in HH when compared with MH (peak: 725 vs. 488 N; mean: 574 vs. 373 N). Energy cost was significantly higher (p ≤ 0.01) in both hypoxic conditions compared with NORM (NORM: 10.4; MH: 11.7; HH: 13.3 kJ·min−1). There were no differences between conditions in heart rate and countermovement jump variables. These results indicate that hypoxic stimuli during HRC exercise alter physical performance and physiological variables and affect how strenuous the exercise is perceived to be. High-intensity resistance circuit training in hypoxia increases the stress on the performance and physiological responses, and these differences must be taken into account to avoid an excessive overload.

Abstract
Nugent, FJ, Comyns, TM, Burrows, E, and Warrington, GD. Effects of low-volume, high-intensity training on performance in competitive swimmers: a systematic review. J Strength Cond Res 31(3): 837–847, 2017—The purpose of this systematic review was to examine the extent and quality of the current research literature to determine the effects of low-volume, high-intensity training (HIT) on physiological performance and swimming performance in competitive swimmers. The methodology followed the preferred reporting items for systematic review and meta-analysis protocol. A search of relevant databases and conference proceedings was performed until December 2015. The inclusion criteria were (a) competitive swimmers, (b) ≥4 weeks HIT intervention, (c) comparison group had to involve a higher training volume, (d) outcome measures of physiological and swimming performance, and (e) all experimental study designs. Quality assessment was performed using the Quality Index checklist. Results indicate that of the 538 studies retrieved, 7 studies met the inclusion criteria. Six of the 7 studies found that an HIT intervention resulted in significant improvements in physiological performance. Four of the 7 studies found that HIT resulted in significant improvements in swimming performance, whereas none of the 7 studies resulted in a reduction in physiological or swimming performance. Despite the positive findings of this review, the short study duration is a limitation to a number of studies. The current evidence on the effects of HIT on performance is promising; however, it is difficult to draw accurate conclusions until further research has been conducted.

Abstract
Spanidis, Y, Stagos, D, Orfanou, M, Goutzourelas, N, Bar-or, D, Spandidos, D, and Kouretas, D. Variations in oxidative stress levels in 3 days follow-up in ultramarathon mountain race athletes. J Strength Cond Res 31(3): 582–594, 2017—The aim of the present study was the monitoring of the redox status of runners participating in a mountain ultramarathon race of 103 km. Blood samples from 12 runners were collected prerace and 24, 48, and 72 hours postrace. The samples were analyzed by using conventional oxidative stress markers, such as protein carbonyls (CARB), thiobarbituric acid reactive substances (TBARS), total antioxidant capacity (TAC) in plasma, as well as glutathione (GSH) levels and catalase (CAT) activity in erythrocytes. In addition, 2 novel markers, the static oxidation-reduction potential marker (sORP) and the capacity oxidation-reduction potential (cORP), were measured in plasma. The results showed significant increase in sORP levels and significant decrease in cORP and GSH levels postrace compared with prerace. The other markers did not exhibit significant changes postrace compared with prerace. Furthermore, an interindividual analysis showed that in all athletes but one sORP was increased, whereas cORP was decreased. Moreover, GSH levels were decreased in all athletes at least at 2 time points postrace compared with prerace. The other markers exhibited great variations between different athletes. In conclusion, ORP and GSH markers suggested that oxidative stress has existed even 3 days post ultramarathon race. The practical applications from these results would be that the most effective markers for short-term monitoring of ultramarathon mountain race–induced oxidative stress were sORP, cORP, and GSH. Also, administration of supplements enhancing especially GSH is recommended during ultramarathon mountain races to prevent manifestation of pathological conditions.

Peces juveniles de corvina aguada, Cynoscion squamipinnis, obtenidos a partir de desoves espontáneos en cautiverio fueron engordados por 355 días en la Estación de Biología Marina Juan Bertoglia Richards (Costa Rica). Ciento cincuenta y dos peces fueron sembrados en tanques de cuatro toneladas a una biomasa total de 82 g m-3, y alimentados con una dieta de 50% proteína, 17.5% carbohidratos, 11.8% lípidos, 16% ceniza y 5% humedad. El oxígeno disuelto fue de 7.12±1.13 mg L-1 (5.68 - 9.13 mg L-1), la salinidad de 31.92±1.65 ups (29.84 - 34.71 ups), y la temperatura de 27.54±0.63°C (26.50 - 28.60°C), condiciones similares a las del Golfo de Nicoya. El peso inicial promedio fue de 3.77±1.15 g (0.3 - 6.2 g). El peso promedio final fue de 132.60±32.96 g (78.5 - 219.3 g). El crecimiento (C) fue de 128.83 g, con una tasa de crecimiento (TC) de 0.36 g d-1, y una tasa específica de crecimiento (TEC) de 1.00 % PC d-1. La tasa de crecimiento relativa (TCR) fue de 0.0053 g g-1 d-1. El factor de conversión alimenticia (FCA) durante todo el periodo fue de 1.8±0.4. La corvina aguada tuvo un crecimiento menor al de otras corvinas, mostró un comportamiento tranquilo, aceptó la dieta peletizada y fue fácil de manipular, por lo que es candidata para la maricultura.
On variable step highly stable 4-stage Hermite-Birkhoff solvers for stiff ODEs
Authors: Nguyen-Ba Truong , Giordano Thierry 
Published: July 2016

Variable-step (VS) \(4\)-stage \(k\)-step Hermite--Birkhoff (HB) methods of order \(p=(k+1)\), denoted by HB\((p)\), are constructed as a combination of linear \(k\)-step methods of order \((p-2)\) and a two-step diagonally implicit \(4\)-stage Runge--Kutta method of order 3 (TSDIRK3) for solving stiff ordinary differential equations. The main reason for considering this class of formulae is to obtain a set of \(k\)-step methods which are highly stable and are suitable for the integration of stiff differential systems whose Jacobians have some large eigenvalues lying close to the imaginary axis. The approach, described in the present paper, allows us to develop \(L\)-stable \(k\)-step methods of order up to 7 and \(L(\alpha)\)-stable methods of order up to 10 with \(\alpha > 64^\circ\). Fast algorithms are developed for solving confluent Vandermonde-type systems of the new methods in O\((p^2)\) operations to obtain HB interpolation polynomials in terms of generalized Lagrange basis functions. The step sizes of these methods are controlled by a local error estimator. Selected HB(\(p\)) of order \(p\), \(p=4,5,\ldots,9\), compare favorably with existing Cash modified extended backward differentiation formulae, MEBDF(\(p\)), \(p=4,5,\ldots,8\) in solving problems often used to test highly stable stiff ODE solvers on the basis of CPU time, number of steps and error at the endpoint of the integration interval.

Objectives. To evaluate the effectiveness of the Safety and Health Involvement For Truckers (SHIFT) intervention with a randomized controlled design. Methods. The multicomponent intervention was a weight-loss competition supported with body weight and behavioral self-monitoring, computer-based training, and motivational interviewing. We evaluated intervention effectiveness with a cluster-randomized design involving 22 terminals from 5 companies in the United States in 2012 to 2014. Companies were required to provide interstate transportation services and operate at least 2 larger terminals. We randomly assigned terminals to intervention or usual practice control conditions. We assessed participating drivers (n = 452) at baseline and 6 months. Results. In an intent-to-treat analysis, the postintervention difference between groups in mean body mass index change was 1.00 kilograms per meters squared (P < .001; intervention = −0.73; control = +0.27). Behavioral changes included statistically significant improvements in fruit and vegetable consumption and physical activity. Conclusions. Results establish the effectiveness of a multicomponent and remotely administered intervention for producing significant weight loss among commercial truck drivers.

Buscamos entender a textualização do político no âmbito do não verbal, analisando a relação de intertextualidade de duas cenas em dois filmes: a escadaria de Odessa, em O Encouraçado Potemkin (1925) e a escadaria da estação de trem em Os Intocáveis (1987). Através do movimento de efeitos metafóricos, trabalha no filme de De Palma uma memória discursiva que aponta tanto a filiação de uma textualidade em termos de montagem a Eiseinstein, quanto a possibilidade de se falar de materialidades e imaterialidades não verbais.
A vályogkunyhótól a mikroprocesszorig: az Egyesített Növekedéselmélet és alapmodelljei
Authors: Földvári Péter 
Published: July 2016

Az egyesített növekedéselmélet célja, hogy a gazdasági fejlődés hosszútávú tendenciáit egységes elméleti keretbe ágyazva magyarázza meg. Ennek megfelelően egy sikeres egyesített modellnek képesnek kell lennie a különböző időszakok, gazdasági rezsimek közötti átmenetek egységes elméleti keretben történő modellezésére. Ebben a tanulmányban, a három növekedési korszak jellemzőinek áttekintése után, két növekedési modellt mutatunk be. Míg a Hansen-Prescott modell elsősorban azt mutatja be, hogy miként zajlott le az átmenet, addig a Galor-Weil modell a megfigyelt folyamatok okaira és összefüggéseire derít fényt.

Két fogyasztási/megtakarítási modell bemutatása
Authors: Buzasi Katalin 
Published: July 2016

A fogyasztási, illetve megtakarítási magatartás két legnagyobb hatású modellje Friedman permanensjövedelem-hipotézise és Modigliani életciklus-hipotézise. A tanulmány áttekintést ad a két elmélet kialakulásának körülményeiről, tartalmáról és következtetéseiről. Ahhoz, hogy még teljesebb képet kapjunk a vizsgálat alapjául szolgáló modellekről, megemlítünk néhány vitát, melyek hozzájárultak az elméletek nem egyértelmű pontjának tisztázásához. Sorra veszünk továbbá olyan lehetőségeket a hipotézisek kiegészítésére, amelyeknek célja a leegyszerűsített, elvont, elméleti síkon jól működő teóriák valóságnak megfelelőbbé tétele.

Közgazdaságtan vagy közgazdaság-tudomány? I. rész
Authors: Móczár József 
Published: July 2016

A cikk alapvető kérdése: vajon tudomány-e a közgazdaságtan, és ha igen, akkor tekinthető-e önálló tudománynak. A választ az elmúlt század legfontosabb eredményeiből kiindulva keresi. A szerző arra a következtetésre jut, hogy napjaink főáramú közgazdasági elméletei nagyrészt Ramsey, Neumann és Haavelmo munkáira vezethetők vissza. Tudománnyá válását nagyban elősegítette a matematika és a természettudományok, főleg a fizika eredményeinek alkalmazása. Mindezt Roy E. Weintraub úgynevezett történeti rekonstrukciós módszerével és Lakatos Imre racionális rekonstrukciója segítségével mutatja meg.

Munkapiaci rugalmatlanság és a munkanélküliségi idősorok egységgyök-tulajdonsága: problémafelvetés
Authors: Kormos János , Czeglédi Pál 
Published: July 2016

A cikk a munkanélküliség idősorainak vizsgálatára vonatkozó irodalmat, illetve az e tesztek mögött meghúzódó közgazdasági magyarázatokat tekinti át. Választ keresünk arra, hogy mi az elméleti alapja a munkanélküliség idősoraiban az egységgyök létezését kutató teszteknek. Amellett érvelünk, hogy az e tesztek előtt álló egyik fő nehézséget a munkapiaci intézményrendszer megváltozása jelenti. A hagyományos egységgyöktesztek emiatt meglehetősen gyengévé válnak, míg a panel egységgyöktesztek a kérdés közgazdasági oldalát egyszerűsítik le. Következtetésünk, hogy az úgynevezett közel egységgyök-folyamatokra vonatkozó tesztek egyfajta kiutat jelenthetnek.

A foglalkoztatásban és termelékenységben bekövetkezett permanens szektorális változások
Authors: Mate Domicián 
Published: July 2016

A tanulmányban a hosszú távon jelentkező ún. „munkahelyetlen” növekedés (jobless growth) kérdésköréből kiindulva elsősorban a munkapiac foglalkoztatási és termelékenységi struktúrájában létrejövő permanens szektorális változásokra (sectoral shifts) koncentráltunk. Vizsgálódásaink során először arra a kérdésre kerestük a választ, hogy a foglalkoztatás struktúrájában bekövetkezett változások a térbeli (az EU-15 országaiban), avagy a szerkezeti (ágazati) tényezőkben játszottak jelentősebb szerepet a vizsgált (1990–2003) időszakban. Mindamellett a munkapiaci termelékenységben bekövetkezett elmozdulásokon keresztül néhány elméleti hipotézist teszteltünk, nevezetesen a strukturális változásokból adódó nyereségek és veszteség (structural bonus & burden) hipotéziseit az ún. hatásarány-elemzésen keresztül. További empirikus vizsgálatokban kitértünk még a szektorális termelékenységben bekövetkezett változásokra különböző képzettségbeli és technológiai összevetések tükrében.
