A unidade informacional de introdutor locutivo no português brasileiro: uma análise baseada em corpus

Este estudo tem como objetivo a analise da unidade informacional usada para sinalizar que o espaco locutivo subsequente apresenta um ponto de vista unitario que difere do restante do texto. Esta unidade e denominada Introdutor Locutivo segundo a Teoria da Lingua em Ato, base teorica deste estudo. A Teoria da Lingua em Ato parte da Teoriados Atos de Fala de Austin e analisa a estrutura informacional de um enunciado levando em consideracao a interface prosodica entre locucao e ilocucao. O enunciado e entendido neste estudo como a menor sequencia linguistica interpretavel pragmaticamente, ou seja, qualquer expressao que possua autonomia pragmatica para realizar uma ilocucao. Portanto, o enunciado independe de uma composicionalidadesintatica e de uma autonomia semântica. Para este estudo foi analisado um subcorpus composto de 10 textos de cerca de 1500 palavras cada, extraidos do C-ORAL-BRASIL, corpus de fala espontânea do Portugues Brasileiro representativo da diatopia mineira e portador da maior variacao diafasica possivel, com o objetivo de obter, assim, umagama variada de ilocucoes e estruturacoes informacionais. O corpus C-ORAL-BRASIL possui a mesma arquitetura e os mesmos criterios de segmentacao do C-ORAL-ROM, corpora de 4 linguas românicas europeias: frances, espanhol, italiano e portugues. Neste trabalho sao descritas as caracteristicas funcionais, distribucionais, prosodicas,morfossintaticas e lexicais da unidade de Introdutor Locutivo em Portugues Brasileiro e tais caracteristicas sao comparadas as caracterististicas da unidade em italiano, lingua a qual ja foi aplicada a mesma base teorica. Para as analises prosodicas foram utilizadosos softwares WinPitch e Praat, atraves dos quais foram feitas medicoes relativas a variacao da media de F0 e da velocidade de elocucao da unidade em estudo em relacao ao restante do enunciado. Algumas conclusoes que emergem do estudo sao as de que o Introdutor Locutivo e mais usado em Portugues Brasileiro do que em italiano e de quena maioria dos casos a unidade introduz a meta-ilocucao de discurso reportado. Os resultados obtidos a partir deste trabalho, alem de contribuirem para o estudo da estrutura informacional da fala espontânea em Portugues do Brasil e para a comparacao interlinguistica com as linguas as quais ja foi aplicada a mesma base teorica aqui utilizada, enfatiza tambem a relevância da abordagem pragmatica para a analise de fenomenos linguisticos dificilmente explicaveis a luz de uma abordagem sintatica.

Rereading of the genetic origins of cancer: the puzzle of all eras

This is a scientific introduction to review the concept of cancer from a purely genetic perspective in which we try to link the development of tumors by the driving force of the evolution of living beings: the mutations. And to prove the assumption that cancer diversity has a parallel route instead of the whole development process of the cell. Calling for expanding the rolling concept of cancer and tumors definition in general. Which may contribute to altering the angle of our vision to this dangerous biological phenomenon. This call is based on the hypothesis that cancer is a genetic phenomenon that has arisen on the margins of the evolution process, that has continued since the beginning of creation. The pieces of evidence and indications that support this view were presented successively.
rORAL: computational platform for the acquisition and remote assessment of images in oral health

The evolution of mobile devices and their general availability creates an opportunity for their use in mobile health scenarios (mHealth). One of the possible use cases includes the use of mobile devices in capturing pictures to document clinical conditions. In oral care, this can be used to enable remote assessment of the oral cavity, for example, for oral health screening in the population. In this work we propose a digital platform to enable studies in oral care, which includes the capture of oral cavity photographs with mobile devices like smartphones, near the subject of care, and the posterior review by experts, using a web application. The proposed platform, named rORAL, consists in an Android application and two web applications. The Android application is used for image acquisition. One of the web applications is for studies management and the other is to manage worklists and to review the clinical cases. The system has been implemented in a functional prototype and was validated in the use case of oral care education with community practice.
Trap assisted tunneling modelling for aSi contact stacks in IBC-SHJ

Interdigitated back contact silicon heterojunction (IBC-SHJ) solar cells have demonstrated 26.6\% world record efficiency by combining outstanding passivation of Si thin film layers with the absence of front shading contact in the crystalline silicon (c-Si) absorber bulk. Furthermore, this type of solar cell merges advantages of c-Si with Si thin film technology that allows for adjustment and tuning of bandgap and Fermi energy in deposited layers, and thus, modifying material properties that also impact the carrier collection. As heterointerfaces tailor to band offset and potential barriers for collecting carriers, the transport is described by thermionic emission and tunneling mechanisms. Moreover, Si thin film layers typically exhibit a defective matrix with characteristic traps and charge distribution that affect solar cell external parameters. Such phenomena involves the so called trap assisted tunneling (TAT) together with trap recombination mechanisms in a complex physical system. In this work, the effect of TAT mechanisms on IBC-SHJ is studied by means of numerical simulations based on TCAD Sentaurus. Firstly, the TAT model is implemented as non-local process. It was found that TAT exhibits a negligible effect on electron collection, but dominates transport mechanisms in case of hole contact. Such an effect depends on band alignment at the doped layer/transparent conductive oxide (TCO) interface, where band-to-band tunneling in combination with TAT describe the transport of holes. In particular, TCO carrier concentration in combination with activation energy of deposited layer allows the collection by either TAT or band-to-band tunneling. In more detail, the density of traps described typically as dangling bond improves the transport of collecting carriers. Thus, the collection of carriers is evaluated in terms of energy and trap concentration, demonstrating that traps with an energy level of 0.5 to 0.7eV over the valence band enhances the FF, and thus, the solar cell performance. Finally, the complete model is calibrated by comparing measured with simulated external parameters from a reference solar cell with and without TAT mechanisms. From this analysis, it is demonstrated that solar cell external parameters deploys more consistent values for Shockley-Read-Hall (SRH) recombination associated to bulk lifetime and surface recombination velocity using TAT model.

Hygrothermal/UV Aging Effect on Visual Aspect and Mechanical Properties of Non-Woven Natural-Fiber Composites

This work aims at studying the effect of hygrothermal and UV cyclic aging on the tensile properties and esthetic characteristics of non-woven composites. The composite materials were thermo-compressed from non-woven mats made up of PP and flax or kenaf fibers. This works included evaluating the change in color appearance and analyzing the variations in tensile properties and damage mechanisms, depending on the aging time. The presence of the UV protection film on the composite surface showed its effectiveness against aging. From visual observations and measurement of colorimetric parameters, it has been proved effective in the reduction of the bleaching and yellowing of the composites. As regards the tensile tests, the UV protection film enabled to stabilize the Young’s modulus after 1-week aging for Kenaf/PP and after 3weeks for Flax/PP. After 4-weeks aging, it halved the number of acoustic emission events related to interfacial decohesion and fiber slippage/pull out for Flax/PP and Kenaf/PP composites.
Autonomous Cars: Research Results, Issues, and Future Challenges

Throughout the last century, the automobile industry achieved remarkable milestones in manufacturing reliable, safe, and affordable vehicles. Because of significant recent advances in computation and communication technologies, autonomous cars are becoming a reality. Already autonomous car prototype models have covered millions of miles in test driving. Leading technical companies and car manufacturers have invested a staggering amount of resources in autonomous car technology, as they prepare for autonomous cars’ full commercialization in the coming years. However, to achieve this goal, several technical and nontechnical issues remain: software complexity, real-time data analytics, and testing and verification are among the greater technical challenges; and consumer stimulation, insurance management, and ethical/moral concerns rank high among the nontechnical issues. Tackling these challenges requires thoughtful solutions that satisfy consumers, industry, and governmental requirements, regulations, and policies. Thus, here we present a comprehensive review of state-of-the-art results for autonomous car technology. We discuss current issues that hinder autonomous cars’ development and deployment on a large scale. We also highlight autonomous car applications that will benefit consumers and many other sectors. Finally, to enable cost-effective, safe, and efficient autonomous cars, we discuss several challenges that must be addressed (and provide helpful suggestions for adoption) by designers, implementers, policymakers, regulatory organizations, and car manufacturers.
Pig farming is a wonderful mixture of scientific precision and massive ignorance

Simulation modeling is an active part of animal nutrition. These complex programs rely on mathematical functions to predict the performance of an animal. The Gompertz equation is a simple, but accurate function that fits animal growth data well. In conjunction with allometry, the growth of a specific genotype can be predicted. Only three parameters are needed to sufficiently describe a genotype, viz. protein weight at maturity (Pm), the Gompertz growth rate parameter (B) and the lipid to protein ratio at maturity (LPRm), These descriptors are lacking for commercial pig genotypes in South Africa, and this hinders the use of models in simulating nutrient requirements. It is the aim of this thesis to estimate these parameters in six South African pig genotypes. Thirty pigs from each of six commercial genotypes were analysed using a serial slaughter method in which pigs were slaughtered at 4 and 14 days of age, and at 30, 40, 70, 80, 90 and 100kg live weight. The animals were choice fed and were houseq in conventional housing facilities, Analyses for protein, lipid, water, and ash contents of the empty body at the respective weights were performed. The results indicated that there were no significant differences between the six genotypes in terms of mature weights or B of the various body chemical components, or between the B values estimated for all components across genotypes. The mean of the estimated values for Pm, Band LPRm were 38,8 ± 2.1 kg, 0.012 ± 0.004 day -1, and 1.16 kg/kg respectively and can therefore be used to adequately describe all six genotypes. The assumption made that all body components have a similar B value is supported.
From Strangers to Friends: Tie Formations and Online Activities in an Evolving Social Network

The authors study how strangers become friends within an evolving online social network. By modeling the coevolution of individual users’ friendship tie formations (when and with whom) and their concurrent online activities, the authors uncover important drivers underlying individuals’ friendship decisions and, at the same time, quantify the resulting peer effects on individuals’ actions. They estimate their model using a novel data set capturing the continuous development of a network and users’ entire action histories within the network. The results reveal that similarity (homophily) with a potential friend, the properties of a potential friend's network, and the potential friend’s domain expertise all play a role in friendship formation. Via prediction exercises, the authors find that stimulating anime watching is the most effective sitewide intervention, which leads to the highest overall site traffic and the largest number of active users, and that recommending a friend of a friend as a potential friend is the most effective strategy in stimulating friendship tie formation. In contrast to the common finding for static networks, the results indicate that seeding to users with the most friends is not the most effective strategy to increase users’ activity levels in an evolving network.
UvA-DARE ( Digital Academic Repository ) Adherence to technology-mediated insomnia treatment : a meta-analysis , interviews , and focus groups

Background: Several technologies have been proposed to support the reduction of insomnia complaints. A user-centered assessment of these technologies could provide insight into underlying factors related to treatment adherence. Objective: Gaining insight into adherence to technology-mediated insomnia treatment as a solid base for improving those adherence rates by applying adherence-enhancing strategies. Methods: Adherence to technology-mediated sleep products was studied in three ways. First, a meta-analysis was performed to investigate adherence rates in technology-mediated insomnia therapy. Several databases were queried for technology-mediated insomnia treatments. After inclusion and exclusion steps, data from 18 studies were retrieved and aggregated to find an average adherence rate. Next, 15 semistructured interviews about sleep-support technologies were conducted to investigate perceived adherence. Lastly, several scenarios were written about the usage of a virtual sleep coach that could support adherence rates. The scenarios were discussed in six different focus groups consisting of potential users (n=15), sleep experts (n=7), and coaches (n=9). Results: From the meta-analysis, average treatment adherence appeared to be approximately 52% (95% CI 43%-61%) for technology-mediated insomnia treatments. This means that, on average, half of the treatment exercises were not executed, suggesting there is a substantial need for adherence and room for improvement in this area. However, the users in the interviews believed they adhered quite well to their sleep products. Users mentioned relying on personal commitment (ie, willpower) for therapy adherence. Participants of the focus groups reconfirmed their belief in the effectiveness of personal commitment, which they regarded as more effective than adherence-enhancing strategies. Conclusions: Although adherence rates for insomnia interventions indicate extensive room for improvement, users might not consider adherence to be a problem; they believe willpower to be an effective adherence strategy. A virtual coach should be able to cope with this “adherence bias” and persuade users to accept adherence-enhancing strategies, such as reminders, compliments, and community building.
