Chunk concatenation evolves with practice and sleep-related enhancement consolidation in a complex arm movement sequence
Authors: Blischke Klaus , Malangré Andreas 
Published: July 2016

Abstract
This paper addresses the notion of chunk concatenation being associated with sleep-related enhancement consolidation of motor sequence memory, thereby essentially contributing to improvements in sequence execution speed. To this end, element movement times of a multi-joint arm movement sequence incorporated in a recent study by Malangré et al. (2014) were reanalyzed. As sequence elements differed with respect to movement distance, element movement times had to be purged from differences solely due to varying trajectory lengths. This was done by dividing each element movement time per subject and trial block by the respective “reference movement time” collected from subjects who had extensively practiced each sequence element in isolation. Any differences in these “relative element movement times” were supposed to reflect element-specific “production costs” imposed solely by the sequence context. Across all subjects non-idiosyncratic, lasting sequence segmentation was shown, and four possible concatenation points (i.e. transition points between successive chunks) within the original arm movement sequence were identified. Based on theoretical suppositions derived from previous work with the discrete sequence production task and the dual processor model (Abrahamse et al., 2013), significantly larger improvements in transition speed occurring at these four concatenation points as compared to the five fastest transition positions within the sequence (associated with mere element execution) were assumed to indicate increased chunk concatenation. As a result, chunk concatenation was shown to proceed during acquisition with physical practice, and, most importantly, to significantly progress some more during retention following a night of sleep, but not during a waking interval.

Authors: Turnagöl Hüseyin Hüsrev 
Published: July 2016

Abstract
The aim of this study was to compare whole and segmental body composition and bone mineral density of collegiate American football players by playing positions. Forty collegiate American football players voluntarily participated in this study. Participants were categorized by playing positions into one of five categories i.e., defensive linemen, offensive linemen, defensive secondary players, offensive secondary players and receivers. Whole body composition and bone mineral density were measured by dual x-ray absorptiometry. Offensive and defensive linemen had higher body mass, a body mass index, lean mass and a fat mass index compared to the remaining three positions and a higher lean mass index compared to offensive secondary players and receivers. Offensive linemen had a higher body fat percentage and lower values of upper to lower lean mass than offensive and defensive secondary players and receivers, and higher total mass to the lean mass ratio and fat mass to the lean mass ratio compared to the other players. Offensive linemen had a higher fat mass index and fat mass to the lean mass ratio than defensive linemen. However, in all other measures they were similar. Offensive and defensive secondary players and receivers were similar with respect to the measured variables. Bone mineral density of the players was within the normal range and no difference in lean mass was observed between the legs. In conclusion, findings of this study showed that the total and segmental body composition profile of collegiate American football players reflected the demands of particular playing positions.

Published: July 2016

Abstract
The study aimed to determine the values of selected aerobic and anaerobic capacity variables, physical profiles, and to analyze the results of on-ice tests performed by ice-hockey players relegated to a lower league. Performance of 24 ice-hockey players competing in the top league in the 2012/2013 season was analysed to this end. In the 2013/2014 season, 14 of them still played in the top league (the control group), while 10 played in the first league (the experimental group). The study was conducted one week after the end of the playoffs in the seasons under consideration. The results revealed that only in the experimental group the analysed variables changed significantly between the seasons. In the Wingate test, significant changes were only noted in mean relative power (a decrease from 9.91 to 9.14 W/kg; p=0.045) and relative total work (a decrease from 299.17 to 277.22 J/kg; p=0.048). The ramp test indicated significantly lower power output in its final stages (364 compared with 384 W; p=0.034), as well as a significant decrease in relative VO2max (from 52.70 to 48.30 ml/min/kg). Blood lactate concentrations were recorded at the 3rd, 6th, 9th and 12th min of recovery after the ramp test. The rate of post-exercise recovery, ∆LA, recorded after the ramp test turned out to be significantly lower. The times recorded in the on-ice “6x30 m stop” test increased from 32.18 to 33.10 s (p=0.047). The study showed that playing in a lower league where games were less intensive, training sessions shorter and less frequent, had an adverse effect on the performance level of the investigated players. Lower VO2max recorded in the study participants slowed down their rates of post-exercise recovery and led to a significantly worse performance in the 6x30 m stop test, as well as lower relative power and relative total work in the Wingate test.

Abstract
The purpose of this study was to investigate the effects of serve and return game situations on physiological responses and match characteristics in professional male tennis players during one hour-long simulated singles tennis matches. Ten internationally ranked tennis players (age 22.2 ± 2.8 years; body height 180.7 ± 4.4 cm; body mass 75.9 ± 8.9 kg) participated in this study. Their physiological responses were measured using two portable analyzers during indoor hard court matches. Ratings of perceived exertion were also determined at the end of the game. The variables describing the characteristics of the matches determined from video recordings were: (a) duration of rallies; (b) rest time; (c) work-to-rest ratio; (d) effective playing time; and (d) strokes per rally. Significant differences (p<0.05) were found between serving and returning conditions in an hour-long simulated singles tennis match in terms of oxygen uptake, a heart rate, ratings of perceived exertion, pulmonary ventilation, respiration frequency and a respiratory gas exchange ratio. In addition, both the heart rate and ratings of perceived exertion responses were moderately correlated with the duration of rallies and strokes per rally (r = 0.60 to 0.26; p<0.05). Taken together, these results indicate that the serve game situation has a significant effect on the physiological response in an hour-long simulated tennis match between professional male tennis players. These findings might be used for the physiological adaptations required for tennis-specific aerobic endurance.
Efficacy of the “pick and roll” offense in top level European basketball teams

Published: July 2016

Abstract
Team offense in basketball games consists of a set of offensive actions carried out with the cooperation of two or more players. Of these actions, the most commonly used in the last decade is the on-ball screen called the “pick and roll.” The aim of this study was to analyze all of the pick and rolls conducted in the Euroleague championship from all of the 24 participating teams and to investigate the possible relationships between success in the pick and roll and overall success of the teams. For this purpose, 12,376 pick and rolls from 502 matches were analyzed and classified in categories according to the end result of the offensive possession. The results showed that the most effective type of pick and roll offense was when a shot was attempted after 2 passes from the pick and roll occurrence, followed by the screener’s shot when he rolled to the basket. Additionally, linear regression analysis confirmed that pick and roll effectiveness could predict the final classification of the teams. Conclusively, coaches of the high level European clubs should focus on training the players to the most efficient phases of the pick and roll offense, so that the chances of winning the championship to be maximized.

Abstract
The present work proposed to study the oxygen uptake slow component (VO2 SC) of breaststroke swimmers at four different intensities of submaximal exercise, via mathematical modeling of a multi-exponential function. The slow component (SC) was also assessed with two different fixed interval methods and the three methods were compared. Twelve male swimmers performed a test comprising four submaximal 300 m bouts at different intensities where all expired gases were collected breath by breath. Multi-exponential modeling showed values above 450 ml·min−1 of the SC in the two last bouts of exercise (those with intensities above the lactate threshold). A significant effect of the method that was used to calculate the VO2 SC was revealed. Higher mean values were observed when using mathematical modeling compared with the fixed interval 3rd min method (F=7.111; p=0.012; η2=0.587); furthermore, differences were detected among the two fixed interval methods. No significant relationship was found between the SC determined by any method and the blood lactate measured at each of the four exercise intensities. In addition, no significant association between the SC and peak oxygen uptake was found. It was concluded that in trained breaststroke swimmers, the presence of the VO2 SC may be observed at intensities above that corresponding to the 3.5 mM-1 threshold. Moreover, mathematical modeling of the oxygen uptake on-kinetics tended to show a higher slow component as compared to fixed interval methods.

Abstract
The aim of this study was to verify the power of VO2max, peak treadmill running velocity (PTV), and running economy (RE), unadjusted or allometrically adjusted, in predicting 10 km running performance. Eighteen male endurance runners performed: 1) an incremental test to exhaustion to determine VO2max and PTV; 2) a constant submaximal run at 12 km·h−1 on an outdoor track for RE determination; and 3) a 10 km running race. Unadjusted (VO2max, PTV and RE) and adjusted variables (VO2max
0.72, PTV0.72 and RE0.60) were investigated through independent multiple regression models to predict 10 km running race time. There were no significant correlations between 10 km running time and either the adjusted or unadjusted VO2max. Significant correlations (p < 0.01) were found between 10 km running time and adjusted and unadjusted RE and PTV, providing models with effect size > 0.84 and power > 0.88. The allometrically adjusted predictive model was composed of PTV0.72 and RE0.60 and explained 83% of the variance in 10 km running time with a standard error of the estimate (SEE) of 1.5 min. The unadjusted model composed of a single PVT accounted for 72% of the variance in 10 km running time (SEE of 1.9 min). Both regression models provided powerful estimates of 10 km running time; however, the unadjusted PTV may provide an uncomplicated estimation.
Energy-Efficient Routing and Spectrum Assignment Algorithm with Physical-Layer Impairments Constraint in Flexible Optical Networks
Authors: Zhao Jijun , Zhang Nawa , Ren Danping , Hu Jinhua 
Published: July 2016

AbstractThe recently proposed flexible optical network can provide more efficient accommodation of multiple data rates than the current wavelength-routed optical networks. Meanwhile, the energy efficiency has also been a hot topic because of the serious energy consumption problem. In this paper, the energy efficiency problem of flexible optical networks with physical-layer impairments constraint is studied. We propose a combined impairment-aware and energy-efficient routing and spectrum assignment (RSA) algorithm based on the link availability, in which the impact of power consumption minimization on signal quality is considered. By applying the proposed algorithm, the connection requests are established on a subset of network topology, reducing the number of transitions from sleep to active state. The simulation results demonstrate that our proposed algorithm can improve the energy efficiency and spectrum resources utilization with the acceptable blocking probability and average delay.

Simulative Investigation on the Effect of Different Parameters on the Performance of IsOWC System
Authors: Singh Mehtab 
Published: July 2016

AbstractInter-satellite communication links are very crucial between satellites orbiting around the earth in order to transmit information between them and also for the purpose of data relaying from one satellite station to other stations and ground stations. Inter-satellite optical wireless communication (IsOWC) links involve the application of optical wireless signals as compared to radio frequency signals used in traditional satellite communication systems. One of the major problems leading to the performance degradation of IsOWC link is the signal degradation due to satellite vibrations also known as pointing errors. In this paper, the performance of an IsOWC communication link has been investigated for different system parameters such as data transmission rates, antenna aperture diameter, transmission power levels, operating wavelength and responsivity of photodiode by analyzing
Spiritual Development through the Chakra
Progression
Authors: Drapkin Jennifer , McClintock Clayton , Lau Elsa , Miller Lisa 
Published: July 2016

Abstract
This pilot study investigates spiritual development as progressing in accordance with chakra
theory. Chakra theory posits that spirituality emerges in a developmental monotonic fashion with
increasing degrees of connection and spiritual awareness. People further into the progression generally
show greater mental health and stronger character virtues, while individuals in earlier stages of
development show greater pathology and lower levels of character virtues. Latent Class Analysis (LCA)
was used in a sample of 1633 adults from the United States to empirically derive five profiles of spiritual
connection, which reflected the monotonic progression predicted by the chakra theory. Participants who
were low on all five variables of spiritual connection (3% of participants) were labeled the “Disconnected”
class, and participants who were high on all five variables were labeled the “Highly Connected” class (16%
of participants). The Disconnected class showed the greatest psychopathology (depressive and anxious
symptoms) and lowest levels of positive psychology traits (gratitude, grit, satisfaction with life, selfcompassion,
and flourishing), while the Highly Connected class showed the lowest psychopathology and
highest levels of positive psychology traits. The other three classes, which fell between the Disconnected
class and the Highly Connected class, carried intermediate levels of psychopathology and character
strengths. Findings support future investigation on a universal progression of spiritual development
based upon chakra theory.
Developing enhanced magnetoimmunosensors based on low-cost screen-printed electrode devices

Published: July 2016

Abstract
Electrochemical magnetoimmunosensors combine a number of issues that guarantee extremely high performance and also compatibility with the study of complex sample matrices. First, analyte immunocapture exploits the high affinity and specificity of antibodies. Second, magnetic particles (MP) provide faster and more efficient immunocapture than binding on two-dimensional structures, separation from nontarget sample components, and concentration of the target analyte. Finally, electrochemical detection supplies sensitivity and fast signal generation using robust and potentially miniaturized measurement equipment and transducers. On the contrary, MP handling is slightly more complex for end-users and more difficult to integrate in point-of-care devices than the manipulation of a classical biosensor. Attempts have been made to automate immunomagnetic binding, and the first robotized systems and platforms for the fluorescent and spectrophotometric detection of magnetoimmunoassays have already reached the market. Among the different types of electrodes available, screen-printed electrodes (SPE) stand out because of their low production cost and yet acceptable performance and interdevice reproducibility, which make them an excellent choice for analytical applications. In addition, each SPE entails a whole electrochemical cell stamped on a planar physical substrate, which makes it possible detection in small volumes and is especially favorable for the magnetic confinement of MP and the integration of microfluidic structures. In this article, we discuss the advantages obtained by using SPE and MP for the production of electrochemical magnetoimmunosensors and the clues for the successful development of such devices. We then revise some of the most outstanding works published in the literature.
Les intuitions édusémiotiques des grands pédagogues : Engagement sémiotique, théorie de l’enquête et narrativité
Authors: Pesce Sébastien 
Published: July 2016

RésuméLes théories de référence de l’édusémiotique offrent un cadre puissant pour repenser l’éducation. Elles nous permettent d’envisager de nouvelles manières d’enseigner, et sont particulièrement heuristiques dans une logique de transfert de la théorie vers la pratique. Mais ce qui est remarquable est la cohérence entre les positions développées par l’édusémiotique et la pensée et les pratiques de certains des “grands pédagogues.” L’hypothèse que je propose d’explorer ici est qu’au travers de l’expérimentation, ces pédagogues ont élaboré des manières d’enseigner cohérentes avec une conception édusémiotique de la cognition, en rupture avec les conceptions transmissives et dualistes.
Egyetemi múzeumok és gyűjtemények Magyarországon, avagy sajátos helyzetű gyűjtemények bemutatása
Authors: Szilágyi Judit 
Published: July 2016

The history and relevance of those museums and collections – owned and maintained by institutions of higher education – leads back to the establishment of the first universities. However, for the last 3 decades, interest in them shows a tendency towards revivalism. The reason for the new attention to university museums can be found in inevitable changes in society and education, as well as in the new tendency for the appreciation of the past and heritage. The goal of this article is to lay down the important principles and knowledge about university museums in general and in Hungary specifically. It can contribute to a Hungarian professional discourse since that has not developed as yet. Thus I describe those fundamental differences that essentially define university museums and collections, such as the complicated and often problematic ownership of these entities and the different target audience that originates from the basic roles namely the apparent focus to teaching and research.
Referring to a survey that had been made between 2007–2011 I list the university museums and collections in Hungary by their registration, but I also found it important to introduce those collections and exhibitions which had not yet been registered. Furthermore I focus on the academic festive occasions, which nourishes the preservation and presentation of the heritage, and which later on can promote the establishment or further maintenance of these unregistered and thus „outlaw” exhibitions and collections.

A Klebelsberg Könyvtár Egyetemi Gyűjteményének küldetése: gyűjteni, feldolgozni, szolgáltatni és megőrizni mindazon dokumentumokat, amelyek a Szegedi Tudományegyetem (SZTE) múltjával és jelenével kapcsolatba hozhatók, és amelyek a jövő nemzedékének is értékes adalékokkal szolgálhatnak. Ennek megfelelően gyűjtőkörébe fényképek, sajtóközlemények, monográfiák (amelyeknek szerzője vagy tárgyköre az egyetemhez kapcsolható), disszertációk és tárgyi emlékek tartoznak. Ezekre épülve a gyűjtemény aktívan bekapcsolódik az egyetem történetére vonatkozó tájékoztató munkába, különféle egyetemtörténeti kiadványok összeállításába, évfordulós kiállítások installálásába, tárgyi emlékek felkutatásába. A gyűjtemény könyvállománya nem különül el egy helyen, nagyrészt a könyvtár raktáraiban található, így az érdeklődök számára nem szabadon hozzáférhető. Az egyéb dokumentumok használata szintén korlátozott feltételekhez kötött,
ugyanakkor az előzetes tájékozódást több elektronikus adatbázis segíti.

The University of Pécs and its predecessor institutions have already started the work around revealing and preserving the history between the two world wars: yearbooks, almanacs, works about the university history have been made. In connection with the academic anniversaries between 1967 and 1992 the collecting of the university history material also began. In 1992 an exhibition had been opened about the history of the medical training of the Medical University of Pécs, and in 2000 about the various detriments of the integrated University of Pécs, presented in the Vasváry House. The Pécs University History Collection 2010 was officially got the rank of public collection in 2010, and in this year the newly arranged, permanent interactive exhibition was opened. The five permanent exhibition halls of the exhibition guide the visitors through the medieval university in Pécs until today's modern university representing the history of higher education in Pécs. The main scope of activities of the University of Pécs History Museum is related to the processing and the history of the university documents, objects, numismatic and fine art, photographs, books and academic journals collection, and making these works available for the public. The institute’s wide collections of treasures are represented with the help of the databases and temporary exhibitions per year.
