Reliability and criterion validity of measurements using a smart phone-based measurement tool for the transverse rotation angle of the pelvis during single-leg lifting

ABSTRACT Objective: The purposes of this study were to determine the intra-rater test–retest reliability of a smart phone-based measurement tool (SBMT) and a three-dimensional (3D) motion analysis system for measuring the transverse rotation angle of the pelvis during single-leg lifting (SLL) and the criterion validity of the transverse rotation angle of the pelvis measurement using SBMT compared with a 3D motion analysis system (3DMAS). Method: Seventeen healthy volunteers performed SLL with their dominant leg without bending the knee until they reached a target placed 20 cm above the table. This study used a 3DMAS, considered the gold standard, to measure the transverse rotation angle of the pelvis to assess the criterion validity of the SBMT measurement. Intra-rater test–retest reliability was determined using the SBMT and 3DMAS using intra-class correlation coefficient (ICC) [3,1] values. The criterion validity of the SBMT was assessed with ICC [3,1] values. Result: Both the 3DMAS (ICC = 0.77) and SBMT (ICC = 0.83) showed excellent intra-rater test–retest reliability in the measurement of the transverse rotation angle of the pelvis during SLL in a supine position. Moreover, the SBMT showed an excellent correlation with the 3DMAS (ICC = 0.99). Conclusion: Measurement of the transverse rotation angle of the pelvis using the SBMT showed excellent reliability and criterion validity compared with the 3DMAS.
A Novel Approach towards Video Compression for Mobile Internet using Transform Domain Technique

As the era, in the internet applications, is of mobile internet, the use of the internet on the cell-phone networks and other mobile networks is increased so much. Also the data rates available on any mobile networks are limited so that the multimedia file transfers on the mobile networks require more time and cost. To reduce the data rates required to transfer multimedia files on the mobile networks, we require one compression algorithm which gives us higher compression with easiness of implementation. So here the paper present one algorithm which is much simpler to implement, as it is based on MPEG-2 then also gives compression in considerable amount, which is comparable to MPEG-4 techniques. The algorithm is implemented on MATLAB version 7.10. 0.499a platform. The input to the encoder is in uncompressed ‘. avi’ format. The testing of the compressed videos is done using MSU video quality measurement tool. General Terms Video compression algorithm useful for mobile internet applications
Health literacy and willingness to use online health information by teens with asthma and diabetes.

OBJECTIVE This study measured health literacy in a population of teens in treatment for asthma or diabetes and tested the association between health literacy and willingness to use online health resources. MATERIALS AND METHODS About 180 patients aged 13-18 years treated for asthma or diabetes in specialty care clinics completed assessments of demographic characteristics, health literacy, and Internet access and use. Teens were provided a resource page listing selected publically available health-related Web sites and asked about perceived ease of use, perceived usefulness, and intent to use the listed Web sites. The relationship between demographic characteristics, health literacy, and online health information use was tested using chi-squared or Fisher's exact test. Predictors of intent to use resource page Web sites were assessed using bivariate and multivariate ordinal logistic regression. RESULTS About 92% of participants had adequate health literacy. Over 50% of participants had previously searched online for health information. Older age was the only significant predictor of health information search. Most teens (79%) reported intent to use at least one Web site from the resource page at least occasionally within the next 3 months. Higher health literacy (odds ratio [OR]=6.24, p<0.01) and stronger perceived usefulness (OR=1.74, p=0.01) were associated with greater intent for regular use, after controlling for demographic and Internet access variables. CONCLUSIONS Teens with lower health literacy searched online for health information as often as peers with higher literacy, but were less likely to express the intent to use recommended sites. Belief in the usefulness of a Web site is the strongest attitudinal predictor of intended future use.
Workload-adaptive process tuning strategy for power-efficient multi-core processors

As more devices are integrated with technology scaling, reducing the power consumption of both high-performance and low-power processors has become the first-class design constraint. Reducing power consumption while satisfying required performance is critical for increasing the operating time of mobile devices and lowering the operating cost of offices and data centers. Meanwhile, dynamic voltage and frequency scaling (DVFS) and clock-gating (CG) techniques have been widely used for two of the most powerful techniques to reduce the power consumption of such processors. Depending on performance and power demands, a processor runs at various performance and power states to trade power with performance. In this paper, we propose process tuning strategy to minimize the average power consumption of multi-core processors that use the DVFS and CG techniques, while providing the same maximum performance. The proposed optimization method incorporates with workload characteristics of commercial high-performance and low-power multi-core processors. The experimental results show that our optimized 32nm technologies for workstation, mobile, and server multi-core processors minimize the average power by up to 13, 18, and 9%, respectively.
Sub-band Implementation of Adaptive Nonlinear Filter for Adaptive Nonlinear Echo Cancellation

The adaptive Volterra filter has been successfully applied in nonlinear acoustic echo cancellation (AEC) systems and nonlinear line echo cancellation systems, but its applications are limited by its required computational complexity and slow convergence rate, especially for systems with long memory length. In this paper, we first apply a more general nonlinear filter, the function expansion nonlinear filter, in the acoustic echo cancellation - the Volterra filter can be regarded as special case of the function expansion nonlinear filter. Then by leveraging to a multi-channel configuration of the function expansion nonlinear filter and the sampling theory for nonlinear systems, we extend linear sub-band delay-less adaptive filter techniques to develop an efficient sub-band implementation of the adaptive function expansion nonlinear filter. The developed sub-band configuration of the adaptive nonlinear filter can greatly improve the convergence rate and reduce the computational complexity of nonlinear echo cancellers, which is shown by analyses and simulations.
The empirical content of theories in judgment and decision making: Shortcomings and remedies

According to Karl Popper, we can tell good theories from poor ones by assessing their empirical content (empirischer Gehalt), which basically reflects how much information they convey concerning the world. “The empirical content of a statement increases with its degree of falsifiability: the more a statement forbids, the more it says about the world of experience. ” Two criteria to evaluate the empirical content of a theory are their level of universality (Allgemeinheit) and their degree of precision (Bestimmtheit). The former specifies how many situations it can be applied to. The latter refers to the specificity in prediction, that is, how many subclasses of realizations it allows. We conduct an analysis of the empirical content of theories in Judgment and Decision Making (JDM) and identify the challenges in theory formulation for different classes of models. Elaborating on classic Popperian ideas, we suggest some guidelines for publication of theoretical work.
Nonlinear Time-Varying Controllers for Uniform Stabilization

This paper is devoted to the topic of (robust) uniform stabilizability of families of linear time-invariant (LTI) plants arising from additive and multiplicative descriptions of unstructured uncertainty. Our results extend some previous work reported in [9], and show that there is no advantage in using general nonlinear time-varying (NLTV) controllers over LTI ones for certain problems of (robust) uniform stabilization. Some auxiliary results on L¿-norm approximation theory are also obtained.
Multinomial Dirichlet Gaussian Process Model for Classification of Multidimensional Data

— We present probabilistic multinomial Dirichlet classification model for multidimensional data and Gaussian process priors. Here, we have considered efficient computational method that can be used to obtain the approximate posteriors for latent variables and parameters needed to define the multiclass Gaussian process classification model. We first investigated the process of inducing a posterior distribution for various parameters and latent function by using the variational Bayesian approximations and important sampling method, and next we derived a predictive distribution of latent function needed to classify new samples. The proposed model is applied to classify the synthetic multivariate dataset in order to verify the performance of our model. Experiment result shows that our model is more accurate than the other approximation methods.
Disambiguating Discourse Connectives for Statistical Machine Translation

This paper shows that the automatic labeling of discourse connectives with the relations they signal, prior to machine translation (MT), can be used by phrase-based statistical MT systems to improve their translations. This improvement is demonstrated here when translating from English to four target languages-French, German, Italian and Arabic-using several test sets from recent MT evaluation campaigns. Using automatically labeled data for training, tuning and testing MT systems is beneficial on condition that labels are sufficiently accurate, typically above 70%. To reach such an accuracy, a large array of features for discourse connective labeling (morpho-syntactic, semantic and discursive) are extracted using state-of-the-art tools and exploited in factored MT models. The translation of connectives is improved significantly, between 0.7% and 10% as measured with the dedicated ACT metric. The improvements depend mainly on the level of ambiguity of the connectives in the test sets.
Sperm competition in bats

Sperm competition is a widespread phenomenon influencing the evolution of male anatomy, physiology and behaviour. Bats are an ideal group for studying sperm competition. Females store fertile sperm for up to 200 days and the size of social groups varies from single animals to groups of hundreds of thousands. This study examines the relationship between social group size and investment in spermatogenesis across 31 species of microchiropteran bat using new and published data on testis mass and sperm length. In addition to male competition, I examined the effects of female reproductive biology on characteristics of spermatogenesis. Comparative studies indicate that relative testis mass is positively related to sperm competition risk in a wide range of taxa. Social group size may also influence the level of sperm competition, and one of the costs of living in groups may be decreased confidence of paternity. I used comparative analysis of independent contrast (CAIC) to control for phylogeny. Using two possible phylogenies and two measures of social group size, I found a significant positive relationship between social group size and testis mass. There was no relationship between testis mass and the dimension of the female reproductive tract or oestrus duration. Sperm length was not significantly related to body mass or group size, nor was it related to oestrus duration.
Exploring the Relationship between Money Attitudes and Maslow's Hierarchy of Needs

This study explores the relationship between basic human needs and money attitudes in a university-age cohort utilizing Maslow's theory of hierarchical needs. Results confirmed relationships between needs and money attitudes. Specifically, all of Maslow's needs appear to be strongly related to the money attitudes of evaluation and anxiety. In addition, men's and women's needs are highly correlated with obsession, budget, anxiety and particularly evaluation. Findings support existing literature and point to the importance of understanding money attitudes and level of need satisfaction among individuals and families, particularly from a counselling and educational standpoint. Implications and possible areas for future research are discussed.
Effects of Social Categorization and Belief Similarity Upon Intergroup Behavior

Recent research has shown that intergroup discrimination occurs with little pretext (e.g., Billig and Tajfel, 1973). The mere categorization of subjects into groups on the basis of a trivial task is sufficient to elicit intergroup discrimination. In Tajfel’s procedure subjects were divided into two groups allegedly on the basis of their preferences for paintings. They were than given the opportunity to divide rewards between members of their own group (ingroup) and members of the other group (outgroup). Subjects displayed a significant tendency to bias their assignment of rewards to favor ingroup persons at the expense of outgroup per-
Sensitivity analysis for phase inductances in Flux-Switching PM machines

This paper investigates the sensitivity of phase inductances to the changes in rotor position and armature current in Flux-Switching PM machines (FSPM). FSPMs exhibit combined advantages of both Switched Reluctance Machines (SRM) and Double Salient PM machines (DSPM). Energy conversion in a FSPM is based on the change of phase inductances, which depends not only on phase current but also on the presence of PMs. To obtain more insight, phase inductances are calculated as functions of both position and current in a 3-phase 12/10 FSPM. Using Finite Element Method (FEM), static (absolute) and incremental (dynamic) inductances are compared for nonlinear operation of the FSPM. A unique behaviour of dq-axes inductances in FSPM is observed, which requires a review of their definitions due to their crucial importance for control systems. Saturation and cross-coupling effects are accounted for in all calculations.
Ontology Alignment: An annotated Bibliography

topics in this research. We talked about types of heterogeneity between ontologies, various mapping representations, classified methods for discovering methods both between ontology concepts and data, and talked about various tasks where mappings are used. In this extended abstract of our talk, we provide an annotated bibliography for this area of research, giving readers brief pointers on representative papers in each of the topics mentioned above. We did not attempt to compile a comprehensive bibliography and hence the list in this abstract is necessarily incomplete. Rather, we tried to sketch a map of the field, with some specific reference to help interested readers in their exploration of the work to-date.
Zur interindividuellen Variabilität affektiver Reaktionen im Verlauf von Freizeit- und Gesundheitssportprogrammen

Positive Effekte sportlicher Aktivitat auf das aktuelle Befinden sind meta-analytisch gut dokumentiert. Eine Generalisierung der Befunde wird dadurch eingeschrankt, dass zunehmend eine hohe interindividuelle Variabilitat beobachtet wird und Prozesse wahrend der Aktivitat defizitar berucksichtigt wurden. Dieser Beitrag geht den Fragen nach, wie gros das Ausmas interindividueller Variabilitat affektiver Reaktionen im Verlauf von gruppenbasierten Freizeit- und Gesundheitssportaktivitaten ist und welchen Einfluss personale Voraussetzungen (Fitnesszustand) und Faktoren der Auseinandersetzung mit der Aktivitat (Beanspruchungserleben, Kompetenzwahrnehmung, positives Gruppenerleben) nehmen. Speziell interessiert, inwieweit affektive Reaktionen in Abhangigkeit vom Zeitpunkt sowie in Abhangigkeit der Intensitat von unterschiedlichen Faktoren beeinflusst werden. Dazu wurden 110 Universitatsangestellte (M = 49.5 Jahre) wiederholt im Rahmen von mehrwochigen Programmen befragt. An insgesamt sechs Terminen wurden Handhe.
Benchmarking the performance of Bhutanese students with the performance of the students from the OECD's PISA countries

Setting international benchmarks for education systems of the Organisation for Economic Co-operation and Development (OECD) countries is one of the goals of the OECD's Programme for International Student Assessment (PISA). However, some countries are not able to participate in PISA, despite their desire to set international benchmarks for their education systems. This article presents a method of setting international benchmarks for a country's school education system, without necessarily participating in PISA, by designing a test using the test items released by PISA for public consumption. The method has been implemented in a study that involved 1,500 Grade 10 students across 60 schools in Bhutan. The students were administered a mathematics test constructed from the PISA Mathematical Literacy test items. The study showed that the performance of Bhutanese students was comparable with the performance of the students from the countries that participated in PISA 2003 and that Bhutan could learn from both high- and low-performing school education systems of those countries.
Foo: a minimal modern OO calculus

We present the Flyweight Object-Oriented (Foo) calculus for the modeling of object-oriented languages. Foo is a simple, minimal class-based calculus, modeling only essential computational aspects and emphasizing larger-scale features (e.g., inheritance and generics). Foo is motivated by the observation that recent language design work focuses on elements not well-captured either by traditional object calculi or by language-specific modeling efforts, such as Featherweight Java. Foo integrates seamlessly both nominal and structural subtyping ideas, leveraging the latter to eliminate the need for modeling object fields and constructors. Comparing to recent formalization efforts in the literature, Foo is more compact, yet versatile enough to be usable in multiple settings modeling Java, C#, or Scala extensions.
Genetic risk of age-related maculopathy. Population-based familial aggregation study.

OBJECTIVE To investigate to what extent age-related maculopathy (ARM) is genetically determined. DESIGN AND SETTING Familial aggregation study based on probands derived from the population-based Rotterdam Study. PARTICIPANTS First-degree relatives of 87 patients with late ARM, i.e., atrophic or neovascular macular degeneration, were compared with first-degree relatives of 135 control subjects without ARM. MAIN OUTCOME MEASURES Presence and stage of ARM as diagnosed on fundus transparencies, odds ratio, lifetime risk, risk ratio, and population-attributable risk. RESULTS Independent of other risk factors, the prevalence of early (odds ratio = 4.8, 95% confidence interval [CI] = 1.8-12.2) and late (odds ratio = 19.8, 95% CI = 3.1-126.0) ARM was significantly higher in relatives of patients with late ARM. The lifetime risk estimate of late ARM was 50% (95% CI = 26%-73%) for relatives of patients vs 12% (95% CI = 2%-16%) for relatives of controls (P < .001), yielding a risk ratio of 4.2 (95% CI = 2.6-6.8). Relatives of patients expressed the various features of ARM at a younger age. The population-attributable risk related to genetic factors was 23%. CONCLUSIONS First-degree relatives of patients with late ARM developed ARM at an increased rate at a relatively young age. Our findings indicate that approximately one fourth of all late ARM is genetically determined and suggest that genetic susceptibility may play an important role in determining the onset of disease.
Calcium-independent stimulation of membrane fusion and SNAREpin formation by synaptotagmin I

Ñeurotransmitter release requires the direct coupling of the calcium sensor with the machinery for membrane fusion. SNARE proteins comprise the minimal fusion machinery, and synaptotagmin I, a synaptic vesicle protein, is the primary candidate for the main neuronal calcium sensor. To test the effect of synaptotagmin I on membrane fusion, we incorporated it into a SNARE-mediated liposome fusion assay. Synaptotagmin I dramatically stimulated membrane fusion by facilitating SNAREpin zippering. This stimulatory effect was topologically restricted to v-SNARE vesicles (containing VAMP 2) and only occurred in trans to t-SNARE vesicles (containing syntaxin 1A and SNAP-25). Interestingly, calcium did not affect the overall fusion reaction. These results indicate that synaptotagmin I can directly accelerate SNARE-mediated membrane fusion and raise the possibility that additional components might be required to ensure tight calcium coupling.
Interpolating physical exercise between instigation to aggress and aggression: the role of irritability and emotional susceptibility

Two studies were conducted using the Buss aggression machine paradigm to investigate the mediational role of physical exercise with respect to subsequent aggression in relation to the presence or absence of previous instigation. The irritability level of subjects was taken into account in the first study, and the subject' emotional susceptibility level in the second study. In both studies sex differences were also considered so that each study resulted in a 2 × 2 × 2 × 2 design with ten subjects in each cell. As far as irritability is concerned, experimental subjects (pedaling on a bicycle ergonometer) delivered higher shocks than controls (who just waited out the 10 min the experimental subjects were pedaling), independent of irritability level or of the presence or absence of previous instigation. When emotional susceptibility was taken into consideration, physical exercise associated with high level of emotional susceptibility and previous instigation resulted in increased intensity of the shocks subsequently delivered. These findings are discussed in terms of the importance of stable personality characteristics that may differentially mediate aggression.
Topoisomerase II and histone deacetylase inhibitors delay the G2/M transition by triggering the p38 MAPK checkpoint pathway

When early prophase PtK1 or Indian muntjac cells are exposed to topoisomerase II (topo II) inhibitors that induce little if any DNA damage, they are delayed from entering mitosis. We show that this delay is overridden by inhibiting the p38, but not the ATM, kinase. Treating early prophase cells with hyperosmotic medium or a histone deacetylase inhibitor similarly delays entry into mitosis, and this delay can also be prevented by inhibiting p38. Together, these results reveal that agents or stresses that induce global changes in chromatin topology during G2 delay entry into mitosis, independent of the ATM-mediated DNA damage checkpoint, by activating the p38 MAPK checkpoint. The presence of this pathway obviates the necessity of postulating the existence of multiple “chromatin modification” checkpoints during G2. Lastly, cells that enter mitosis in the presence of topo II inhibitors form metaphase spindles that are delayed in entering anaphase via the spindle assembly, and not the p38, checkpoint.
An iterative voting method based on word density for text classification

In this paper we present an iterative voting (IV) method using the density based weighting for text classification. An in-class word density is used to weight for each word in a topic, so that the word in documents has an array of weights to vote for given topics, and the highest scored topic will be labeled. During the voting process, the iteration strategy is applied for improving the classification effectiveness. This method shows the competitive performance against SVM, NB, KNN, and it has better time efficiency.
