Extraction of attributes and knowledge rules for sport skill by TAM network

In this paper, we discuss sport technique evaluation of motion analysis modeled by TAM network as a kind of neural networks. We recorded continuous forehand strokes of each table tennis player into video frames, and analyzed the trajectory pattern of nine measurement markers attached at the body of players with the motion analysis model. We extracted input attributes and technique rules in order to classify the skill level of players of table tennis, i.e., expert player, middle level player and beginner. In addition, we analyzed movement of the markers in order to understand how to improve skill in table tennis technique.
The Jet-Disk Connection and Blazar Unification

We discuss the relation between the power carried by relativistic jets and the nuclear power provided by accretion for a group of blazars, including flat-spectrum radio quasars (FSRQs) and BL Lac objects. They are characterized by good-quality broadband X-ray data provided by the BeppoSAX satellite. The jet powers are estimated using physical parameters determined from uniformly modeling their spectral energy distributions. Our analysis indicates that for FSRQs the total jet power is of the same order as the accretion power. We suggest that blazar jets are likely powered by energy extraction from a rapidly spinning black hole (BH) through the magnetic field provided by the accretion disk. FSRQs must have large BH masses (108-109 M☉) and high, near-Eddington accretion rates. For BL Lac objects, the jet luminosity is larger than the disk luminosity. This can be understood within the same scenario if BL Lac objects have masses similar to FSRQs but accrete at largely subcritical rates, whereby the accretion disk radiates inefficiently. Thus, the "unification" of the two classes into a single blazar population, previously proposed on the basis of a spectral sequence governed by luminosity, finds a physical basis.
Dependency Theory: An Introduction

Dependency Theory developed in the late 1950s under the guidance of the Director of the United Nations Economic Commission for Latin America, Raul Prebisch. Prebisch and his colleagues were troubled by the fact that economic growth in the advanced industrialized countries did not necessarily lead to growth in the poorer countries. Indeed, their studies suggested that economic activity in the richer countries often led to serious economic problems in the poorer countries. Such a possibility was not predicted by neoclassical theory, which had assumed that economic growth was beneficial to all (Pareto optimal) even if the benefits were not always equally shared.
Advanced technology mapping for standard-cell generators

In this paper, a new algorithm for technology mapping aiming at standard-cell generators is proposed. The proposed method has features that explore several AND/OR circuit decompositions by using an n-ary tree representation of the circuit. In the covering step, the cell that leads to the smaller depth increase is chosen. Depth calculation is not limited to the subject tree and takes into account all previously mapped trees representing sub-expressions used as inputs. Experimental results show gains in circuit depth measured by the number of gates in series, as well as in area measured by transistor count when compared to SIS mapping approach using the same libraries. The gain in circuit depth translates to better timing as verified by SPICE simulations.
Immediate Implant Placement in the Anterior Maxilla with Customized Impression Coping: A Clinical Case Presentation

Implant placement in the anterior maxilla remains a challenge to even the most experienced clinician. Immediate implant placement is a risky procedure in itself and only successful in limited cases. To combine these modalities is expected to have a variety of complications and possible negative outcome. Due to the pressure of patients’ lifestyles and time constricting careers, there is an increased demand for combined procedures. Immediate implant placement have been researched extensively and with the increased success rate of dental implants it is becoming the preferred choice of treatment by clinician and patient. Optimal aesthetics is difficult to obtain after surgical implant placement, especially when treating the anterior maxillary incisor area. Various guidelines have been put in place with regards to the planning, surgical execution and restorative phases of implant treatments in order to optimize the clinical results. This clinical case study is representative of such instance, when following the correct guidelines, a successful outcome is made possible. The case report includes the planning, execution and outcome stages of an immediate implant in the anterior maxilla.
Comparison of Area-Based and Individual Tree-Based Methods for Predicting Plot-Level Forest Attributes

Approaches to deriving forest information from laser scanner data have generally made use of two methods: the area-based and individual tree-based approaches. In this paper, these two methods were evaluated and compared for their abilities to predict forest attributes at the plot level using the same datasets. Airborne laser scanner data were collected over the Evo forest area, southern Finland, with an averaging point density of 2.6 points/m2. Mean height, mean diameter and volume were predicted from laser-derived features for plots (area-based method) or tree height, diameter at breast height and volume for individual trees (individual tree-based method) using random forests technique. To evaluate and compare the two forest inventory methods, the root-mean-squared error (RMSE) and correlation coefficient (R) between the predicted and observed plot-level values were computed. The results indicated that both area-based method (with an RMSE of 6.42% for mean height, 10.32% for mean diameter and 20.90% for volume) and individual tree-based method (with an RMSE of 5.69% for mean height, 10.77% for mean diameter and 18.55% for volume) produced promising and compatible results. Increase in point density is expected to increase the accuracy of the individual tree-based technique more than that of the area-based technique.
Stress Detection for PTSD via the StartleMart Game

Computer games have recently shown promise as a diagnostic and treatment tool for psychiatric rehabilitation. This paper examines the positive impact of affect detection and advanced game technology on the treatment of mental diagnoses such as Post Traumatic Stress Disorder (PTSD). For that purpose, we couple game design and game technology with stress detection for the automatic profiling and the personalized treatment of PTSD via game-based exposure therapy and stress inoculation training. The PTSD treatment game we designed forces the player to go through various stressful experiences while a stress detection mechanism profiles the severity and type of PTSD via skin conductance responses to those in-game stress elicitors. The initial study and analysis of 14 PTSD-diagnosed veteran soldiers presented in this paper reveals clear correspondence between diagnostic standard measures of PTSD severity and skin conductance responses. Significant correlations between physiological responses and subjective evaluations of the stressfulness of experiences, represented as pair wise preferences, are also found. We conclude that this supports the use of the simulation as a relevant treatment tool for stress inoculation training. This points to future avenues of research toward discerning between degrees and types of PTSD using game-based diagnostic and treatment tools.
A New Temporal Error Concealment Scheme Based on Multiple Reference Frames

Abstract-H.264 adopts variable length coding and interprediction techniques, so compressed image is very sensitive to channel error. Meanwhile errors will influence subsequent frames, easily leading to the distortion of rebuilding images. To enhance the quality of reconstructed images, this text proposes a weighted outer boundary matching algorithms based on multiple reference frames, which exploits the characteristic of H.264 and improves outer boundary matching algorithm. The simulation results show that for video sequences with rapidly changing motions and various packet loss rate the proposed algorithm can highly improve the quality of reconstructed video and obtain a gain of about 0.2～1dB in PSNR，compared with error concealment algorithm in JM .
Handling drop‐out in longitudinal studies

Drop‐out is a prevalent complication in the analysis of data from longitudinal studies, and remains an active area of research for statisticians and other quantitative methodologists. This tutorial is designed to synthesize and illustrate the broad array of techniques that are used to address outcome‐related drop‐out, with emphasis on regression‐based methods. We begin with a review of important assumptions underlying likelihood‐based and semi‐parametric models, followed by an overview of models and methods used to draw inferences from incomplete longitudinal data. The majority of the tutorial is devoted to detailed analysis of two studies with substantial rates of drop‐out, designed to illustrate the use of effective methods that are relatively easy to apply: in the first example, we use both semi‐parametric and fully parametric models to analyse repeated binary responses from a clinical trial of smoking cessation interventions; in the second, pattern mixture models are used to analyse longitudinal CD4 counts from an observational cohort study of HIV‐infected women. In each example, we describe exploratory analyses, model formulation, estimation methodology and interpretation of results. Analyses of incomplete data requires making unverifiable assumptions, and these are discussed in detail within the context of each application. Relevant SAS code is provided.

Steep voltage gain quadratic boost converter with a switched-coupled inductor

This paper presents a new scheme of the very high voltage gain quadratic boost converter. The additional advantage of the proposed topology is the continuous input current. The scheme is based on a combination of the quadratic boost converter and switched-coupled-inductor. The study analyses the operation in continuous and discontinuous modes and obtains the basic fundamental relations in steady state including the formulas for the voltage stresses across the switch and the diodes. A 100 W laboratory prototype was built and verified. The experimental results confirmed the theoretical expectations.
Blockade of current through single calcium channels by Cd2+, Mg2+, and Ca2+. Voltage and concentration dependence of calcium entry into the pore

We studied the blocking actions of external Ca2+, Mg2+, Ca2+, and other multivalent ions on single Ca channel currents in cell-attached patch recordings from guinea pig ventricular cells. External Cd or Mg ions chopped long-lasting unitary Ba currents promoted by the Ca agonist Bay K 8644 into bursts of brief openings. The bursts appear to arise from discrete blocking and unblocking transitions. A simple reaction between a blocking ion and an open channel was suggested by the kinetics of the bursts: open and closed times within a burst were exponentially distributed, the blocking rate varied linearly with the concentration of blocking ion, and the unblocking rate was more or less independent of the blocker concentration. Other kinetic features suggested that both Cd2+ and Mg2+ lodge within the pore. The unblocking rate was speeded by membrane hyperpolarization or by raising the Ba concentration, as if blocking ions were swept into the myoplasm by the applied electric field or by repulsive interaction with Ba2+. Ca ions reduced the amplitude of unitary Ba currents (50% inhibition at approximately 10 mM [Ca]o with 50 mM [Ba]o) without detectable flicker, presumably because Ca ions exit the pore very rapidly following Ba entry. However, Ca2+ entry and exit rates could be resolved when micromolar Ca blocked unitary Li+ fluxes through the Ca channel. The blocking rate was essentially voltage independent, but varied linearly with Ca concentration (rate coefficient, 4.5 X 10(8) M-1s-1); evidently, the initial Ca2+-pore interaction is outside the membrane field and much faster than the overall process of Ca ion transfer. The unblocking rate did not vary with [Ca]o, but increased steeply with membrane hyperpolarization, as if blocking Ca ions were driven into the cell. We suggest that Ca is both an effective permeator and a potent blocker because it dehydrates rapidly (unlike Mg2+) and binds to the pore with appropriate affinity (unlike Cd2+). There appears to be no sharp dichotomy between "permeators" and "blockers," only quantitative differences in how quickly ions enter and leave the pore.
Value-based program characterization and its application to software plagiarism detection

Identifying similar or identical code fragments becomes much more challenging in code theft cases where plagiarizers can use various automated code transformation techniques to hide stolen code from being detected. Previous works in this field are largely limited in that (1) most of them cannot handle advanced obfuscation techniques; (2) the methods based on source code analysis are less practical since the source code of suspicious programs is typically not available until strong evidences are collected; and (3) those depending on the features of specific operating systems or programming languages have limited applicability. Based on an observation that some critical runtime values are hard to be replaced or eliminated by semantics-preserving transformation techniques, we introduce a novel approach to dynamic characterization of executable programs. Leveraging such invariant values, our technique is resilient to various control and data obfuscation techniques. We show how the values can be extracted and refined to expose the critical values and how we can apply this runtime property to help solve problems in software plagiarism detection. We have implemented a prototype with a dynamic taint analyzer atop a generic processor emulator. Our experimental results show that the value-based method successfully discriminates 34 plagiarisms obfuscated by SandMark, plagiarisms heavily obfuscated by KlassMaster, programs obfuscated by Thicket, and executables obfuscated by Loco/Diablo.
Adaptive Iterative Block-Delayed Partitioned Viterbi Algorithm

A new adaptive iterative block-delayed partitioned Viterbi algorithm (AIBD-PVA) receiver for the MIMO frequency-selective fading channel is proposed. In the classic PVA, tentative decisions are used for the feedback between the trellis detectors of each transmit antenna. The block-delayed PVA uses more reliable temporary decisions in the feedback loop. The proposed algorithm adapts the number of iterations used to improve the reliability of the feedback decisions depending on the detection conditions, thus resulting in an improved BER performance without adding unnecessary complexity. It is observed that MIMO systems with higher numbers of antennas have a more remarkable BER performance improvement, since they rely more on the feedback between the trellis detectors.
Burnout symptoms amongst drug and alcohol service employees: Gender differences in the interaction between work and home stressorS

Abstract The relationship between work and home-based stressors in predicting burnout symptoms was examined amongst 120 drug and alcohol service employees. Staff who reported high levels of burnout on the Maslach Burnout Inventory across all three scales of Emotional Exhaustion, Depersonalization and Personal Accomplishment were compared with a sample of low burnout employees. High burnout was associated with younger age, larger agency size, high levels of total work stressors, work overload, and daily hassles and a lower level of peer cohesion. Regression analyses revealed that male gender, younger age, work overload, role ambiguity and daily hassles were significant predictors of Emotional Exhaustion. Younger age was also a significant predictor of Depersonalization. Marked differences were found in the way in which males and females responded to work and non-work stressors and the interaction between these variables. For women, a significant interaction was found between total work stressors and home-b.
Signature Pedagogy: A Framework for Thinking about Management Education

This issue is about cases and projects, two staples of management education. As I pondered the issue I wondered what my editorial could contribute that would be new about these two venerable management pedagogies. Then one day, while reading in the field of the scholarship of teaching and learning (SOTL), I came across a new and intriguing concept: signature pedagogy. Reading about signature pedagogies left me with some questions about education for the management profession. In this editorial I will explain some of what I have learned from my reading and then go beyond the articles in this issue to raise a bigger question for our profession. According to Lee Shulman, former President of the Carnegie Foundation for the Advancement of Teaching, signature pedagogies are distinctive ways of teaching that characterize the educational process in a specific profession (Shulman, 2005a, 2005b) or discipline (Gurung, Chick & Haynie, 2009). They are also pervasive, cutting across programs, courses and institutions that offer training for that profession. Familiar examples include the Socratic method of case analysis in law, clinical rounds in medicine, student teaching in education, and studio pedagogy in architecture. Signature pedagogies also “nearly always entail public student performance” (Shulman, 2005, p. 57), making students both visible and accountable to teachers and to peers. Although signature pedagogies may differ across disciplines, they share three overarching learning goals. Professional education is a synthesis of three apprenticeships:
Determinants of wikipedia quality: the roles of global and local contribution inequality

The success of Wikipedia and the relative high quality of its articles seem to contradict conventional wisdom. Recent studies have begun shedding light on the processes contributing to Wikipedia's success, highlighting the role of coordination and contribution inequality. In this study, we expand on these works in two ways. First, we make a distinction between global (Wikipedia-wide) and local (article-specific) inequality and investigate both constructs. Second, we explore both direct and indirect effects of these inequalities, exposing the intricate relationships between global inequality, local inequality, coordination, and article quality. We tested our hypotheses on a sample of a Wikipedia articles using structural equation modeling and found that global inequality exerts significant positive impact on article quality, while the effect of local inequality is indirect and is mediated by coordination
UPV translation system for IWSLT 2009

In this paper, we describe the machine translation system developed at the Polytechnic University of Valencia, which was used in our participation in the International Workshop on Spoken Language Translation (IWSLT) 2009. We have taken part only in the Chinese-English BTEC Task. In the evaluation campaign, we focused on the use of our hybrid translation system over the provided corpus and less effort was devoted to the use of pre- and post-processing techniques that could have improved the results. Our decoder is a hybrid machine translation system that combines phrase-based models together with syntax-based translation models. The syntactic formalism that underlies the whole decoding process is a Chomsky Normal Form Stochastic Inversion Transduction Grammar (SITG) with phrasal productions and a log-linear combination of probability models. The decoding algorithm is a CYK-like algorithm that combines the translated phrases inversely or directly in order to get a complete translation of the input sentence.
Study on Quantum Parallel Processing by Adiabatic Quantum Computation in Bernstein-Vazirani Problem

Adiabatic quantum computation has been proposed as quantum parallel processing with adiabatic evolution by using a superposition state to solve combinatorial optimization problem, then it has been applied to many problems like satisfiability problem. Among them, Deutsch and Deutsch-Jozsa problems have been tried to be solved by using adiabatic quantum computation. In this paper, we modify the adiabatic quantum computation and propose to solve Bernstein-Vazirani problem more efficiently by a method with higher observation probability.

Performance Scalability of a Cooperative Coevolution Multiobjective Evolutionary Algorithm

Recently, numerous Multiobjective Evolutionary Algorithms (MOEAs) have been presented to solve real life problems. However, a number of issues still remain with regards to MOEAs such as convergence to the true Pareto front as well as scalability to many objective problems rather than just bi-objective problems. The performance of these algorithms may be augmented by incorporating the coevolutionary concept. Hence, in this paper, a new algorithm for multiobjective optimization called SPEA2-CC is illustrated. SPEA2-CC combines an MOEA, Strength Pareto Evolutionary Algorithm 2 (SPEA2) with Cooperative Coevolution (CC). Scalability tests have been conducted to evaluate and compare the SPEA2- CC against the original SPEA2 for seven DTLZ test problems with a set of objectives (3 to 5 objectives). The results show clearly that the performance scalability of SPEA2-CC was significantly better compared to the original SPEA2 as the number of objectives becomes higher.
CMBS Subordination, Ratings Inflation, and Regulatory‐Capital Arbitrage

Using detailed origination and performance data on a comprehensive sample of commercial mortgageâ€ backed security (CMBS) deals, along with their underlying loans and a set of similarly rated residential mortgageâ€ backed securities (RMBS), we apply reducedâ€ form and structural modeling strategies to test for regulatoryâ€ capital arbitrage and ratings inflation in the CMBS market. We find that the spread between CMBS and corporateâ€ bond yields fell significantly for ratings AA and AAA after a loosening of capital requirements for highly rated CMBS in 2002, whereas no comparable drop occurred for lower rated bonds (which experienced no similar regulatory change). We also find that CMBS rated below AA upgraded to AA or AAA significantly faster than comparable RMBS (for which there was no change in riskâ€ based capital requirements). We use a structural model to investigate these results in more detail and find that little else changed in the CMBS market over this period except for the rating agencies' persistent reductions in subordination levels between 1997 and late 2007. Indeed, had the 2005 vintage CMBS used the subordination levels from 2000, there would have been no losses to the senior bonds in most CMBS structures.
