CHANGES IN SKILL AND PHYSICAL FITNESS FOLLOWING TRAINING IN TALENT‐IDENTIFIED VOLLEYBALL PLAYERS

This study investigated the effect of a skill-based training program on measurements of skill and physical fitness in talent-identified volleyball players. Twenty-six talented junior volleyball players (mean ± SE age, 15.5 ± 0.2 years) participated in an 8-week skill-based training program that included 3 skill-based court sessions per week. Skills sessions were designed to develop passing, setting, serving, spiking, and blocking technique and accuracy as well as game tactics and positioning skills. Coaches used a combination of technical and instructional coaching, coupled with skill-based games to facilitate learning. Subjects performed measurements of skill (passing, setting, serving, and spiking technique and accuracy), standard anthropometry (height, standing-reach height, body mass, and sum of 7 skinfolds), lower-body muscular power (vertical jump, spike jump), upper-body muscular power (over-head medicine-ball throw), speed (5-and 10-m sprint), agility (T-test), and maximal aerobic power (multistage fitness test) before and after training. Training induced significant (p < 0.05) improvements in spiking, setting, and passing accuracy and spiking and passing technique. Compared with pretraining, there were significant (p < 0.05) improvements in 5-and 10-m speed and agility. There were no significant differences between pretraining and posttraining for body mass, skinfold thickness, lower-body muscular power, upper-body muscular power, and maximal aerobic power. These findings demonstrate that skill-based volleyball training improves spiking, setting, and passing accuracy and spiking and passing technique, but has little effect on the physiological and anthropometric characteristics of players.
Sliding mode control for a ball and arc system

This paper considers the problem of designing and implementing a stabilizing controller for an electromechanical system, called the ball and arc system. This system is nonlinear and underactuated. Moreover, the equilibrium of this system is open-loop unstable. Stabilization of this system is a challenging task and it is suitable for serving as a testbed for research and education in nonlinear control systems. In this paper, the mathematical model of the system is derived to facilitate the controller design. Based on sliding mode control, a stabilizing controller is designed to achieve locally asymptotic stability of the system. The experimental apparatus is constructed, and the controller is implemented. The simulation and experimental results are given to demonstrate the effectiveness of the control scheme.
Ambulatory Blood Pressure Is Associated With Polymorphic Variation in P 2 X Receptor Genes

The P2X receptor gene family encodes a series of proteins that function as ATP-gated nonselective ion channels. P2X receptor channels are involved in transducing aldosterone-mediated signaling in the distal renal tubule and are potential candidate genes for blood pressure regulation. We performed a family based quantitative genetic association study in 248 families ascertained through a proband with hypertension to investigate the relationship between common genetic variation in the P2X4, P2X6, and P2X7 genes and ambulatory blood pressure. We genotyped 28 single nucleotide polymorphisms, which together captured the common genetic variability in the 3 genes. We corrected our results for multiple comparisons specifying a false discovery rate of 5%. We found significant evidence of association between the single nucleotide polymorphism rs591874 in the first intron of the P2X7 gene and blood pressure. The strongest association was found for nighttime diastolic blood pressure (P 0.0032), although association was present for both systolic and diastolic blood pressures measured by an observer during the day and at night. Genotypes were associated with a 0.2 SD ( 2.5 mm Hg) difference in night diastolic blood pressure per allele and accounted for 1% of the total variability in this measurement. Other suggestive associations were found, but these were nonsignificant after correction for multiple testing. These genetic data suggest that drugs affecting P2X receptor signaling may have promise as clinical antihypertensive agents. (Hypertension. 2008;52:980-985.)
Robust Photometric Stereo in a scattering medium via Low-Rank Matrix Completion and Recovery

Photometric Stereo is a popular method for 3D reconstruction from images due to its high level of details handling. However, when it is used in a scattering medium such as lakes and oceans, the recovery result will be negatively impacted by the light absorption, light scattering and the impurities in the water. In this paper, we present a new method to solve the problem of better 3D reconstruction via Low-Rank Matrix Completion and Recovery. First, we use the dark points, like shadows and darkness in the water to fit the scattering effect distribution and then remove the scattering from the image. Next, we use the Robust Principal Component Analysis method (RPCA) to recover the image by removing the sparse noise including shadows, impurities and some corrupted points caused by backscatter compensation. Finally, we combine the RPCA results and the least-squares (LS) results to get the surface normal and accomplish the 3D reconstruction. Extensive experimental results demonstrate that our method achieves more accurate estimates of surface normal and 3D reconstruction than previous techniques.
Comparison of the main sequence of reflexive saccades and the quick phases of optokinetic nystagmus

BACKGROUND/AIMS Abnormalities in the saccadic main sequence are an important finding and may indicate pathology of the ocular motor periphery or central neurological disorders. In young or uncooperative patients it can be difficult eliciting a sufficient number of saccades to measure the main sequence. It is often assumed that the quick phases of optokinetic nystagmus (OKN) are identical to saccades. If this were the case, it would be feasible to use OKN, an involuntary response that is easily evoked, as a simple way of eliciting many saccades. The aim of this study was to determine whether reflexive saccades and the quick phases of OKN are indeed identical, and whether OKN quick phases could have a clinical role in identifying patients with slow saccades. METHODS OKN and reflexive saccades were recorded from 10 healthy adults using an infrared limbus eye tracker and bitemporal DC electro-oculography simultaneously. OKN was stimulated by rotating a full field patterned curtain around the subject at 10–50°/s. Reflexive saccades were elicited to red LED targets at 5–20° eccentricity. RESULTS OKN quick phases tended to have a longer duration compared to saccades, but these differences were not significant. OKN quick phases had a slightly lower peak velocity compared to saccades, which was statistically significant (p<0.05). CONCLUSION The main sequence for duration is the same for reflexive saccades and OKN quick phases. The main sequence for peak velocity is slightly faster for reflexive saccades than OKN quick phases, but the difference is unlikely to be of clinical significance. As an illustration of the potential of this technique, the authors demonstrate that OKN quick phases show similar slowness to saccades in a child with brainstem pathology caused by Gaucher disease type III. It is concluded that recording OKN may be a simple clinical means for approximating the main sequence.
Evaluating methods for controlling depth perception in stereoscopic cinematography

Existing stereoscopic imaging algorithms can create static stereoscopic images with perceived depth control function to ensure a compelling 3D viewing experience without visual discomfort. However, current algorithms do not normally support standard Cinematic Storytelling techniques. These techniques, such as object movement, camera motion, and zooming, can result in dynamic scene depth change within and between a series of frames (shots) in stereoscopic cinematography. In this study, we empirically evaluate the following three types of stereoscopic imaging approaches that aim to address this problem. (1) Real-Eye Configuration: set camera separation equal to the nominal human eye interpupillary distance. The perceived depth on the display is identical to the scene depth without any distortion. (2) Mapping Algorithm: map the scene depth to a predefined range on the display to avoid excessive perceived depth. A new method that dynamically adjusts the depth mapping from scene space to display space is presented in addition to an existing fixed depth mapping method. (3) Depth of Field Simulation: apply Depth of Field (DOF) blur effect to stereoscopic images. Only objects that are inside the DOF are viewed in full sharpness. Objects that are far away from the focus plane are blurred. We performed a human-based trial using the ITU-R BT.500-11 Recommendation to compare the depth quality of stereoscopic video sequences generated by the above-mentioned imaging methods. Our results indicate that viewers' practical 3D viewing volumes are different for individual stereoscopic displays and viewers can cope with much larger perceived depth range in viewing stereoscopic cinematography in comparison to static stereoscopic images. Our new dynamic depth mapping method does have an advantage over the fixed depth mapping method in controlling stereo depth perception. The DOF blur effect does not provide the expected improvement for perceived depth quality control in 3D cinematography. We anticipate the results will be of particular interest to 3D filmmaking and real time computer games.
Nonlinear data analysis and multilayer perceptrons

The correspondence between multilayer perceptrons (MLPs) with linear processing elements and classical data analysis methods (principal component analysis, discriminant analysis) was shown by P. Galinari et al. (see Proc. IEEE ICNN-88, p.I-391-9, 1988). The authors extend their results to the nonlinear case and show that MLP with nonlinear elements approximates the nonlinear data analysis methods. The classical linear data analysis methods are first formulated and solved from the viewpoint of least mean squared error approximation. Nonlinear data analysis methods are then formulated and solved from the same viewpoint. The close relationship between the nonlinear MLP and backpropagation as well as the nonlinear data analysis methods are discussed, and some simulation results are given. <<ETX>>
On Computational Models of the Evolution of Music: From the Origins of Musical Taste to the Emergence of Grammars

Evolutionary computing is a powerful tool for studying the origins and evolution of music. In this case, music is studied as an adaptive complex dynamic system and its origins and evolution are studied in the context of the cultural conventions that may emerge under a number of constraints (e.g. psychological, physiological and ecological). This paper introduces three case studies of evolutionary modelling of music. It begins with a model for studying the role of mating-selective pressure in the evolution of musical taste. Here the agents evolve “courting tunes” in a society of “male” composers and “female” critics. Next, a mimetic model is introduced to study the evolution of musical expectation in a community of autonomous agents furnished with a vocal synthesizer, a hearing system and memory. Finally, an iterated learning model is proposed for studying the evolution of compositional grammars. In this case, the agents evolve grammars for composing music to express a set of emotions.
Physicochemical Characterization of Casein Phosphopeptide-Amorphous Calcium Phosphate Nanocomplexes*

Milk caseins stabilize calcium and phosphate ions and make them available to the neonate. Tryptic digestion of the caseins yields phosphopeptides from their polar N-terminal regions that contain clusters of phosphorylated seryl residues. These phosphoseryl clusters have been hypothesized to be responsible for the interaction between the caseins and calcium phosphate that lead to the formation of casein micelles. The casein phosphopeptides stabilize calcium and phosphate ions through the formation of complexes. The calcium phosphate in these complexes is biologically available for intestinal absorption and remineralization of subsurface lesions in tooth enamel. We have studied the structure of the complexes formed by the casein phosphopeptides with calcium phosphate using a range of physicochemical techniques including x-ray powder diffraction, scanning electron microscopy, transmission electron microscopy, and equilibrium binding analyses. The amorphous nature of the calcium phosphate phase was confirmed by two independent methods: x-ray powder diffraction and selected area diffraction. In solution, the ion activity product of a basic amorphous calcium phosphate phase was the only ion product that was a function of bound phosphate independent of pH, consistent with basic amorphous calcium phosphate being the phase stabilized by the casein phosphopeptides. Detailed investigations of calcium and calcium phosphate binding using a library of synthetic homologues and analogues of the casein phosphopeptides have revealed that although the fully phosphorylated seryl-cluster motif is pivotal for the interaction with calcium and phosphate, other factors are also important. In particular, calcium binding and calcium phosphate stabilization by the peptides was influenced by peptide net charge, length, and sequence.

Nowadays, mobile terminal has become an indispensable element in people’s daily life as the advent of post-PC era, the security issue of these mobile platforms plays a pivotal role in this information technology era. As Android accounts for approximately 80% in the third quarter of 2013, the importance of its potential security risks cannot be neglected. This research started from the critical analysis of the nature of threats from the perspectives of Google and mobile carrier, third-party security applications and user behavior. From these analysis results, a cross-sectional examination was used to derive several practical suggestions for the sake of solving the problems existing currently in the Android phones.
Depression and schizophrenia

Depressive symptoms commonly occur in schizophrenia and have a significant impact on the distress and burden of the illness. Yet they are often overlooked, inadequately characterised by current classification systems and not consistently integrated into treatment. We discuss nosology, practical and clinical implications of symptom differentiation, and the role of causal and confounding factors, including iatrogenic, as targets for therapeutic intervention. The evidence base of psychosocial and psychotropic management is reviewed, with recommendations for the treatment of established syndromal depression in people with schizophrenia.
Policy-based architecture to enable autonomic communications - a position paper

The increase in complexity of network management systems and a consequent lack of association to business requirements has driven the need for autonomic communications. By integrating context information, autonomic computing can provide more efficient means to counter technical problems found in complex network systems and at the same time address associated business requirements. In this paper, we propose an autonomic communications architecture that manages complexity through policy-based management where we incorporate a shared information model integrated with knowledge-based reasoning mechanisms to provide self- governaning behavior.
The Curse of Non-Investment Grade Countries . 1

Among the most influential theories of contagion, those based on liquidity arguments have received very little attention in the empirical work. This paper fills part of this gap. Mexico was upgrade from noninvestment to investment grade in March of 2000. This paper examines the impact of this event on the properties of the transmission of shocks between Mexico and several Latin American countries. The paper shows that there is a statistically significant change in the propagation of shocks around the time the upgrade was announced. Moreover, the change in the estimated coefficients can explain between one fourth and a third of the unconditional comovement that these assets experienced before the upgrade. This is strong evidence in favor of the theories of contagion based on market structure as the source of the propagation mechanism. From the methodological point of view, the paper extends existing identification procedures that solve the problem of estimation in linear simultaneous equations models. The methodology can be used in other Macro and Finance applications where the problem of endogenous variables becomes an important limitation. JEL Classification Numbers: F30, C32, C10
Wujud kebudayaan Masyarakat Adat Cikondang dalam melestarikan lingkungan

This study departs from human life lived long enough in a community, where the community will create a rule or a handle on life that can be used as a way of survival for the creation of a safe, serene and peaceful. The rule could be religious and also can be a culture. Indigenous peoples with all its potential able to be creative to build an environment that is completely self-contained and is also able to preserve the nature of the damage. As a result of the natural environment inhabited by indigenous communities today rescued from various natural disasters. This phenomenon, would be an interesting study material for study. The Society has a certain cultural values that differ from one another. The indigenous peoples are a society that is in life comes with a quirk inherited his ancestors, either in the form of a view of life, religious traditions and values of other cultures that sought to be maintained and implemented in his life as a commandment of life for the benefit of their ancestors The Cikondang society known as the Sunda ethnic and categorized as indigenous communities, because until now still cling to the traditions of his ancestors. It stands out that of the indigenous peoples Cikondang Cikondang is the persistence of indigenous peoples to preserve and utilize the environment to life. This can be seen, when the rainy season Cikondang region is not exposed to landslides, even a water source can be fully utilized for agriculture, so that agricultural produce in abundance. Likewise third dry season Cikondang indigenous peoples do not worry about lack of water even position in the hills of the mountains.
Permutation-Based Semi-Fragile Watermark Scheme

Tamper proofing is a crucial problem in the watermarking application. Aiming at the credibility of multimedia, we present a semi-fragile watermark based on the image permutation. Watermarking detection is performed without resorting to the host image and it is only controlled by secrete keys, thus the whole scheme does not have certain security gaps. The simulation experiments show that it can survive the JPEG compression and effectively specify the region of the image that has been modified maliciously.
Development of a Combined In Vitro Physiologically Based Kinetic (PBK) and Monte Carlo Modelling Approach to Predict Interindividual Human Variation in Phenol-Induced Developmental Toxicity

With our recently developed in vitro physiologically based kinetic (PBK) modelling approach, we could extrapolate in vitro toxicity data to human toxicity values applying PBK-based reverse dosimetry. Ideally information on kinetic differences among human individuals within a population should be considered. In the present study, we demonstrated a modelling approach that integrated in vitro toxicity data, PBK modelling and Monte Carlo simulations to obtain insight in interindividual human kinetic variation and derive chemical specific adjustment factors (CSAFs) for phenol-induced developmental toxicity. The present study revealed that UGT1A6 is the primary enzyme responsible for the glucuronidation of phenol in humans followed by UGT1A9. Monte Carlo simulations were performed taking into account interindividual variation in glucuronidation by these specific UGTs and in the oral absorption coefficient. Linking Monte Carlo simulations with PBK modelling, population variability in the maximum plasma concentration of phenol for the human population could be predicted. This approach provided a CSAF for interindividual variation of 2.0 which covers the 99th percentile of the population, which is lower than the default safety factor of 3.16 for interindividual human kinetic differences. Dividing the dose-response curve data obtained with in vitro PBK-based reverse dosimetry, with the CSAF provided a dose-response curve that reflects the consequences of the interindividual variability in phenol kinetics for the developmental toxicity of phenol. The strength of the presented approach is that it provides insight in the effect of interindividual variation in kinetics for phenol-induced developmental toxicity, based on only in vitro and in silico testing.
Chinese Tone and Vowel Processing Exhibits Distinctive Temporal Characteristics: An Electrophysiological Perspective from Classical Chinese Poem Processing

Classical Chinese poems have strict regulations on the acoustic pattern of each syllable and are semantically meaningless. Using such poems, this study characterized the temporal order of tone and vowel processing using event-related potentials (ERPs). The target syllable of the poem was either correct or deviated from the correct syllable at tone, vowel or both levels. Vowel violation elicited a negative effect between 300 and 500 ms regardless of the tone correctness, while tone violation elicited a positive effect between 600 and 1000 ms. The results suggest that the vowel information was available earlier than the tone information. Moreover, there was an interaction between the effect of vowel and tone violations between 600 and 1000 ms, showing that the vowel violation produced a positive effect only when the tone was correct. This indicates that vowel and tone processing interacts in the later processing stage, which involves both error detection and reanalysis of the spoken input. Implications of the present results for models of speech perception are discussed.
