Changes in Physical Activity and Psychological Variables Following a Web-Based Motivational Interviewing Intervention: Pilot Study

Background Web-based interventions for enhancing physical activity participation are in demand for application in health care settings. Recent research suggests Web-based interventions that are based on motivational interviewing are effective to increase physical activity. It is unclear whether motivational interviewing can influence targeted psychological variables such as perceived readiness, willingness, and ability to participate in physical activity. Objective The aims of this study were to determine whether there were changes in physical activity and psychological variables associated with readiness, willingness, and perceived ability to participate in physical activity following completion of a novel Web-based intervention. The goal of the motivational interviewing–based intervention was to increase physical activity. Methods Twenty-three underactive or inactive urban dwelling adults were recruited at a medical office for participation in a 4-session Web-based intervention lasting approximately 15 minutes per week. Sessions were based on principles of motivational interviewing. Assessment of physical activity was conducted using pedometers immediately prior to intervention participation (pre) and immediately post intervention (post1). Self-report assessments of physical activity and psychological variables were conducted using online surveys at pre, post1, and again at one month following intervention participation (post2). Results Comparisons of pre and post1 pedometer recordings revealed significant increases in steps per day (t 22=2.09, P=.049). There were also significant changes in total physical activity energy expenditure per week (χ2 2=8.4, P=.02) and in moderate intensity physical activity energy expenditure per week (χ2 2=13.9, P<.001) over time following participation in the Web-based intervention. Significant changes in psychological variables following participation in the Web-based intervention included: (1) change in stage classification over time (χ2 2=21.5, P<.001), where the percentage of participants classified in the action or maintenance stages of change in physical activity increased over time (pre=25% [6/24], post1=71% [17/24], post2=68% [15/22]); (2) decreases in self-reported decisional balance cons (F 2,42=12.76, P<.001); (3) increases in self-reported decisional balance pros (F 2,42=16.19, P<.001); (4) increases in physical activity enjoyment (F 2,20=3.85, P=.04); and (5) increases in self-efficacy (F 2,42=3.30, P=.047). Conclusions The Web-based intervention piloted in this study shows preliminary promise as a tool to promote physical activity in health care settings. Additional research is needed to test the effectiveness of motivational interviewing compared to a control condition and to refine content by considering mediation by psychological variables in a larger sample.
A New Subband Adaptive Filtering Algorithm for Sparse System Identification with Impulsive Noise

This paper presents a novel subband adaptive filter (SAF) for system identification where an impulse response is sparse and disturbed with an impulsive noise. Benefiting from the uses of -norm optimization and -norm penalty of the weight vector in the cost function, the proposed -norm sign SAF (-SSAF) achieves both robustness against impulsive noise and remarkably improved convergence behavior more than the classical adaptive filters. Simulation results in the system identification scenario confirm that the proposed -norm SSAF is not only more robust but also faster and more accurate than its counterparts in the sparse system identification in the presence of impulsive noise.
Nanofluidic reverse electrodialysis platform using controlled assembly of nanoparticles for high power energy generation

This paper presents a novel microplatform for high power energy generation based on reverse electrodialysis. The effective cation-selective membrane for power generations is realized between two microfluidic channels using geometrically controlled in situ self-assembled nanoparticles with cost-effective and simple way. Nano-interstices between the assembled nanoparticles have a role as the collective three-dimensional nanochannel networks and they can increase the generated power, significantly. The proposed system can contributes to supply power sources to miniaturized devices and be also used to studies and investigate nanoscale electrokinetics by changing sizes, materials, and shape of the assembled nanoparticles, or geometry control of microchannel.

Breast conservation therapy for stage I or stage II breast cancer: a meta-analysis of randomized controlled trials.

BACKGROUND We carried out a meta-analysis to determine the effectiveness of breast conservation therapy (BCT) or mastectomy (MT) for stage I or stage II breast cancer. METHODS A fully recursive literature search was conducted in the Cochrane Controlled Trials Register Databases, Medline, EMBASE and Chinese Biomedical Literature Database in any language. Randomized controlled trials (RCTs) were considered for inclusion. Analyses were carried out using RevMan software. RESULTS In all, 18 RCTs including a total of 9388 patients were included. The meta-analysis showed that the overall survival in 3, 5, 10, 15 and 20 years and the locoregional recurrence rate in 3, 5, 15 and 20 years were not statistically significantly different between group BCT and group MT, but 10-year locoregional recurrence rate increased in group BCT. The sensitivity analysis indicated that both overall survival and locoregional recurrence rate were not statistically significant difference between group BCT and group MT. In the subgroup analysis, there was no significant difference in OS and locoregional recurrence rate between group BCT and group MT, but 20-year locoregional recurrence rate was statistically significantly higher in group BCT than group MT for women with tumors 2 cm or smaller. CONCLUSION BCT was better choice than MT for women with stage I or stage II breast cancer.
Efficiency of a second‐generation HIV‐1 protease inhibitor studied by molecular dynamics and absolute binding free energy calculations

A subnanomolar inhibitor of human immunodeficiency virus type 1 (HIV‐1) protease, designated QF34, potently inhibits the wild‐type and drug‐resistant enzyme. To explain its broad activity, the binding of QF34 to the wild‐type HIV‐1 protease is investigated by molecular dynamics simulations and compared to the binding of two inhibitors that are used clinically, saquinavir (SQV) and indinavir (IDV). Analysis of the flexibility of protease residues and inhibitor segments in the complex reveals that segments of QF34 were more mobile during the dynamics studies than the segments of SQV and IDV. The dynamics of hydrogen bonding show that QF34 forms a larger number of stable hydrogen bonds than the two inhibitors that are used clinically. Absolute binding free energies were calculated with molecular mechanics–generalized Born surface area (MM–GBSA) methodology using three protocols. The most consistent results were obtained using the single‐trajectory approach, due to cancellation of errors and inadequate sampling in the separate‐trajectory protocols. For all three inhibitors, energy components in favor of binding include van der Waals and electrostatic terms, whereas polar solvation and entropy terms oppose binding. Decomposition of binding energies reveals that more protease residues contribute significantly to the binding of QF34 than to the binding of SQV and IDV. Moreover, contributions from protease main chains and side chains are balanced in the case of QF34 (52:48 ratio, respectively), whereas side chain contributions prevail in both SQV and IDV (main‐chain:side‐chain ratios of 41:59 and 45:55, respectively). The presented results help explain the ability of QF34 to inhibit multiple resistant mutants and should be considered in the design of broad‐specificity second‐generation HIV‐1 protease inhibitors.

Experiencia de pérdida de un ser querido

Desde el momento en que venimos al mundo hasta el dia en que nos vamos de el, invariablemente pasaremos por experiencias de muerte. La asumimos como una realidad inevitable, universal y unica en nuestra vida. Muy frecuentemente, nos encontramos con personas que llegan a ser abatidas profundamente en su estructura emocional, llegando incluso a quedarse en este estado de una manera extendida y autodestructiva, otros en cambio tienen una experiencia menos dolorosa y con menor gasto energetico. Como se refirio antes, a traves del tiempo estas experiencias de perdida han sido exhaustivamente estudiadas y en consecuencia existen multiples aportaciones bibliograficas y guias clinicas sobre las diferentes intervenciones; sin embargo la intencion de este trabajo de investigacion es documentar la experiencia de perdida de las personas adultas que han perdido un ser querido, explicado desde una teoria donde se prioriza a la persona y pretende comprender la experiencia desde su propia vivencia y su mundo privado.
Design and implementation of a network application architecture for thin clients

This paper explores the issues and the techniques of enabling multimedia applications for the thin client computing. Our study on the network applications over thin clients is devoted to the universal plug-in architecture which supports multimedia applications over thin clients. With the proposed architecture, the universal plug-in technique is devised to shift jobs from thin clients to a supporting server, thus reducing the computing overhead required by the thin clients. In addition, this plug-in architecture is implemented and empirically evaluated It is shown by our experiments that the proposed architecture not only significantly enhances the multimedia capability of thin clients but also reduces the memory consumed by the clients for various applications, showing the very advantage of the universal plug-in architecture for thin clients of limited resources.
Depression and anxiety among elderly earthquake survivors in China

This study investigated depression and anxiety among Chinese elderly earthquake survivors, addressing relevant correlations. We sampled one earthquake-prone city, utilising the Geriatric Depression Scale and Beck Anxiety Inventory. In addition, explorative factor analysis and structural equation model methods were used. Results indicated elderly earthquake survivors exhibited symptoms of moderate depression and anxiety; depression and anxiety are highly positively correlated. The overlap between these two psychological problems may be due to subjective fear and motoric dimensions; subjective fear and motoric dimensions of Beck Anxiety Inventory are more strongly related to Geriatric Depression Scale domains. The two scales exhibit high reliability and validity.
Desenvolvimento de antenas planares reconfiguráveis em estruturas com metasuperfícies

No Brasil e no mundo, a evolucao do setor de telecomunicacoes tem sido cada vez mais requisitada como uma clara consequencia do crescimento exponencial da demanda por sistemas de comunicacao sem fio. Neste cenario, a integracao de multiplos padroes wireless em uma unica plataforma, antena reconfiguravel, tambem conhecida como antena sintonizavel, esta atraindo muita atencao. Estruturas metasurfaces tem sido extensivamente utilizadas nos ultimos anos para alcancar o aperfeicoamento de antenas, dentre eles, a reconfiguracao. Uma metasuperficie (tambem referida como um metafilm) e o equivalente de uma superficie metamaterial. Mais precisamente, um metafilm e uma superficie com uma distribuicao de pequenos dispersores arranjados ao longo de uma regiao do espaco, de modo a obter comportamentos eletromagneticos desejaveis. Para muitas aplicacoes, metasuperficies podem ser usadas no lugar de metamateriais, pois possuem como vantagem principal ocupar menos espaco fisico do que as estruturas tridimensionais dos metamateriais, oferecendo a possibilidade de perdas reduzidas, o que tem gerado grande interesse. Neste contexto, esta dissertacao de mestrado apresenta a simulacao, o projeto e a implementacao de estruturas de antenas planares acopladas a estruturas de metasurfaces a fim de realizar reconfiguracao de antenas em frequencia, polarizacao e multibanda, para aplicacoes em comunicacoes sem fio. A analise das estruturas das antenas e realizada com o auxilio de ferramentas computacionais. Prototipos sao construidos e medidos, para fins de comprovacao experimental. Os resultados obtidos em medicoes e simulacoes apresentam uma boa concordância.
Recommender systems for UML class diagrams.

Modelos UML sao usados de varias formas na engenharia de software. Eles podem modelar desde requisitos ate todo o software, e compreendem varios diagramas. O diagrama de classes, o mais popular dentre os diagramas da UML, faz uso de varios elementos UML e adornos, tais como abstracao, interfaces, atributos derivados, conjuntos de generalizacao, composicoes e agregacoes. Atualmente, nao ha maneira facil de encontrar este tipo de diagrama com base nestas caracteristicas para a reutilizacao ou a aprendizagem por tarefas de exemplo. Por outro lado, Sistemas de Recomendacao sao ferramentas e tecnicas que sao capazes de descobrir os elementos mais adequados para um usuario, dentre muitos outros. Existem varias tecnicas de recomendacao, que usam informacoes dos elementos de varias maneiras, ao uso da opiniao de outros usuarios. Sistemas de recomendacao ja foram utilizados com sucesso em varios problemas de engenharia de software. Este trabalho tem como objetivo propor e avaliar (i) uma representacao baseada em conteudo para diagramas de classe e as preferencias do usuario,(ii) um novo algoritmo de recomendacao baseado no conhecimento, (iii) a aplicacao deste algoritmo e outros dois outros do estado da arte para a recomendacao de diagramas de classe UML e (iv) uma avaliacao destas abordagens contra uma sugestao aleatoria. Para atingir este objetivo, foi realizado um estudo de caso com estudantes de ciencia da computacao e egressos. Depois de comparar os algoritmos, os nossos resultados mostram que, para o nosso conjunto de dados, todos eles sao melhores do que uma recomendacao aleatoria.

We demonstrated photorefractive time-domain differential phase detection method with Sb: Sn<inf>2</inf>P<inf>2</inf>S<inf>6</inf> (SPS) which has very fast response speed. SPS crystal can improve the phase detection speed in holographic data storage than the other photorefractive material.
Intraoperative application of geometric three-dimensional mitral valve assessment package: a feasibility study.

OBJECTIVE To study the feasibility of using 3-dimensional (3D) echocardiography in the operating room for mitral valve repair or replacement surgery. To perform geometric analysis of the mitral valve before and after repair. DESIGN Prospective observational study. SETTING Academic, tertiary care hospital. PARTICIPANTS Consecutive patients scheduled for mitral valve surgery. INTERVENTIONS Intraoperative reconstruction of 3D images of the mitral valve. RESULTS One hundred and two patients had 3D analysis of their mitral valve. Successful image reconstruction was performed in 93 patients-8 patients had arrhythmias or a dilated mitral valve annulus resulting in significant artifacts. Time from acquisition to reconstruction and analysis was less than 5 minutes. Surgeon identification of mitral valve anatomy was 100% accurate. CONCLUSIONS The study confirms the feasibility of performing intraoperative 3D reconstruction of the mitral valve. This data can be used for confirmation and communication of 2-dimensional data to the surgeons by obtaining a surgical view of the mitral valve. The incorporation of color-flow Doppler into these 3D images helps in identification of the commissural or perivalvular location of regurgitant orifice. With improvements in the processing power of the current generation of echocardiography equipment, it is possible to quickly acquire, reconstruct, and manipulate images to help with timely diagnosis and surgical planning.
The role of holistic face processing in acquired prosopagnosia: evidence from the composite face effect

ABSTRACT Faces are processed more holistically than other objects, and it has been suggested that the loss of holistic face processing causes acquired prosopagnosia. Support for this hypothesis comes from several cases who failed to show holistic face effects as well as the absence of reports of prosopagnosics with unequivocally normal holistic face perception. The current study examines the relationship between holistic face processing and prosopagnosia by testing seven acquired prosopagnosics with the face composite task, a classic measure of holistic face processing. To enhance the robustness of the findings, each prosopagnosic was tested with two versions of the composite task showing upright faces. We also tested an inverted condition to exclude the possibility that more general factors account for composite effects for upright faces. Four of the seven acquired prosopagnosic participants showed consistent upright face composite effects with minimal inverted face composite effects. We conclude that severe face processing deficits can co-occur with intact holistic face processing and that factors other than a loss of holistic processing contribute to the perceptual and recognition deficits in acquired prosopagnosia.
Multicast routing infrastructure in ATM networks

Communication via computer networks has been growing rapidly. Technology has gained momentum. Industry, international organizations, and businesses, have started relying on networks to provide reliable, supportive, fast, and easy methods to maintain transactions between their branches. Issues such as bandwidth, scalability, and efficiency became pertinent parameters that had to be configured at all costs. Also, information needs to be sent from one site to several sites. All of this is happening on packet switched networks. With the introduction of asynchronous transfer mode (ATM), the speed and quality of service of networks have increased tremendously. Still, the necessity of sending one information to several sites instantaneously has been unresolved. This research paper broadens this perspective, and introduces a new architecture for the future that will enable multicast routers to route packets. This paper also reviews the current state of multicast protocols, highlights the missing features, motivates the design, and develops the enhanced multicast protocols. A new architecture is based upon a hybrid system of distributed databases and a centralized server. Simulation and results of the proposed architecture are also described in detail.
Estudo da influência de diversas medidas de similaridade na previsão de séries temporais utilizando o algoritmo KNN-TSP

Series temporais podem ser entendidas como qualquer conjunto de observacoes que se encontram ordenadas no tempo. Dentre as varias tarefas possiveis com dados temporais, uma que tem atraido crescente interesse, devido a suas varias aplicacoes, e a previsao de series temporais. O algoritmo k-Nearest Neighbor - Time Series Prediction (kNN-TSP) e um metodo nao-parametrico de previsao de series temporais que apresenta como uma de suas vantagens a facilidade de aplicacao, quando comparado aos metodos parametricos. Apesar da maior facilidade na determinacao de seus parâmetros, algumas questoes relacionadas continuam em aberto. Este trabalho esta focado no estudo de um desses parâmetros: a medida de similaridade. Esse parâmetro foi avaliado empiricamente utilizando diversas medidas de similaridade em um grande conjunto de series temporais que incluem series artiﬁciais, com caracteristicas sazonais e caoticas, e varias series reais. Foi realizado tambem um estudo de caso comparativo entre a precisao da previsao do algoritmo kNN-TSP e a dos metodos de Medias Moveis (MA), Auto-regressivos de Medias Moveis Integrados Sazonais (SARIMA) univariado e SARIMA multivariado, em uma serie de ﬂuxo diario de pacientes na Area de Emergencia de um hospital coreano. Neste trabalho e ainda proposta uma abordagem para o desenvolvimento de uma medida de similaridade hibrida, que combine caracteristicas de varias medidas. Os resultados obtidos neste trabalho demonstram que as medidas da Norma Lp apresentam vantagem sobre as demais medidas avaliadas, devido ao seu menor custo computacional e por apresentar, em geral, maior precisao na previsao de dados temporais utilizando o algoritmo kNN-TSP. Apesar de na literatura, em geral, a medida Euclidiana ser adotada como medida de similaridade, a medida Manhattan pode ser considerada candidata interessante para deﬁnir a similaridade entre series temporais, devido a nao apresentar diferenca estatisticamente signiﬁcativa com a medida Euclidiana e possuir menor custo computacional. A medida proposta neste trabalho, nao apresenta resultados signiﬁcantes, mas apresenta-se promissora para novas pesquisas. Com relacao ao estudo de caso, o algoritmo kNN-TSP, com apenas o parâmetro de medida de similaridade otimizado, alcanca um erro consideravelmente inferior a melhor conﬁguracao com MA, e pouco maior que as melhores conﬁguracoes dos metodos SARIMA univariado e SARIMA multivariado, sendo essa diferenca inferior a um por cento.
Approche neuronale pour l’estimation des transferts thermiques dans un fluide frigoporteur diphasique

La propriété associative des réseaux neurologiques artificiels et de leur capacité inhérente d’apprendre et identifier des rapports fortement non linéaires et complexes, les trouve idéalement convenus à une étendue des applications large dans le domaine du froid direct et indirect. Cet article traite les applications potentielles des réseaux neurones artificiels dans la particularité des problèmes thermiques soulevés par l’utilisation des fluides frigoporteurs diphasiques, tels que les coulis de glace (mélange de solutions binaires aqueuses et de cristaux de glace) dans les installations de distribution du froid. L’utilisation de ce type d’installation permet de diminuer, les quantités des fluides frigorigènes traditionnels, ainsi que les problèmes qu’ils engendrent, de réduire les volumes de stockage et les consommations d’électricité. La stratégie d’obtention du RN s'articule sur l'élaboration d'un programme sur MATLAB, comportant plusieurs boucles où on fait varier les algorithmes d’apprentissages, les fonctions d’activations, le nombre de couches cachées et le nombre de neurones dans chaque couche, afin de minimiser la fonction du coût sous contrainte d’une erreur relative fixée. Le modèle neuronal conçu a permis d’une part de reproduire avec une très bonne précision les données expérimentales tirées directement de littérature et d’autre part une estimation meilleure et plus précise des valeurs calculées par rapport aux modèles classiques (basé sur la formulation générale de la méthode enthalpique) des transferts thermiques dans le cas des solutions binaires dispersées sous forme d’émulsions ou de mini-émulsions subissant un changement de phase tirées directement de littérature.
