13. Effect of contrast and gaps between Vernier stimulus elements on sweep visual evoked potential measurements of human cortical Vernier responses
The present paper focuses on a classic hyperacuity, Vernier acuity-the ability to discriminate breaks in the collinearity of lines or edges on the order of only arcseconds of visual angle. We measured steady-state sweep visual evoked potentials (sVEPs) in response to 6 Hz periodic breaks in collinearity (Vernier offsets) in horizontal squarewave gratings. Ve

14. Um estudo sobre o papel de medidas de similaridade em visualização de coleções de documentos / A study on the role of similarity measures in visual text analytics
Information visualization techniques, such as similarity based point placement, are used for generating of visual data representation that evidence some patterns. These techniques are sensitive to data quality, which depends of a very influential preprocessing step. This step involves cleaning the text and in some cases, detecting terms and their weights, as

15. Estudo avaliativo da informação mútua generalizada e de métricas clássicas como medidas de similaridade para corregistro em imagens fractais e cerebrais / Evaluative study of the generalized mutual information and classical metrics as similarity measures for coregistration of brain images and fractals.
A integração de diferentes modalidades de imagens médicas possibilita uma análise mais detalhada de seu conteúdo, visando-se um diagnóstico mais preciso da patologia presente. Este processo, conhecido como corregistro, busca o alinhamento das imagens através da transformação rígida (ou não rígida) das mesmas, por algoritmos matemáticos de distor

16. Estudo da influÃncia de diversas medidas de similaridade na previsÃo de sÃries temporais utilizando o algoritmo KNN-TSP / Study of the influence of similarity measures in Time Series Prediction with the kNN-TSP algorithm
SÃries temporais podem ser entendidas como qualquer conjunto de observaÃÃes que se encontram ordenadas no tempo. Dentre as vÃrias tarefas possÃveis com dados temporais, uma que tem atraÃdo crescente interesse, devido a suas vÃrias aplicaÃÃes, Ã a previsÃo de sÃries temporais. O algoritmo k-Nearest Neighbor - Time Series Prediction (kNN-TSP) Ã um

17. Morfometria radiográfica e tomográfica em dígitos de bovinos e bubalinos / Radiographic and tomographic morphometry in digiti of the cattle and buffaloes
Radiographic and computed tomography (CT) findings may contribute to the diagnosis and prognosis of diseases based on knowledge of digits morphometric reference values. Some breeds of cattle and buffaloes still require determinations of these values for the digits. Thus, the objective with this research was to compare and correlate the condyles and phalanges

18. Carriage frequency, phenotypic and genotypic characteristics of Staphylococcus aureus isolated from dialysis and kidney tranplant patients at a hosptial in northern Paraná
The objective of the present study was to determine the frequency of Staphylococcus aureus nasal carriage among dialysis and kidney transplant patients, to identify the antimicrobial resistance profile of these strains and to verify their genetic profiles with the RW3A primer. The study included 159 individuals, comprising 111 dialysis and 48 kidney transpla

19. Fractal analysis of agricultural nozzles spray
Fractal scaling of the exponential type is used to establish the cumulative volume (V) distribution applied through agricultural spray nozzles in size x droplets, smaller than the characteristic size X. From exponent d, we deduced the fractal dimension (Df) which measures the degree of irregularity of the medium. This property is known as 'self-similarity'.

20. A desigualdade em saúde e o baixo peso ao nascer : uma revisão sistemática com metanálise
Considering the hypothesis that an excessive use of new technologies and the lack of heath resources can present similar outcomes concerning low weight rates at birth (LWB), it was analyzed the association between the social standing, which was obtained from the maternal schooling, profession and income, and the low weight rates at birth. It deals with a lit

21. Recuperação de vídeos comprimidos por conteúdo / Content-based retrieval of compressed videos
Recent advances in the technology have enabled the increase of the availability of video data, creating large digital video collections. This has spurred great interest in systems that are able to manage those data in a efficient way. Making efficient use of video information requires the development of powerful tools to extract high-level semantics from low

22. Clinical and radiographic study of the morphology of the stylohyoid complex in patients with Temporomandibular Disorders and Orofacial Pain. / Estudo clínico e radiográfico dos aspectos morfológicos da cadeia estilo-hióidea em sujeitos com disfunção temporomandibular e dor orofacial
The relationship between temporomandibular disorders and Eagle\ s syndrome occurs due to the similarity of symptoms. The knowledge gained about the Eagle\ s syndrome shows that its symptoms can be very easily confused with other types of craniomandibular disorders and numerous other diseases found in regions of the skull, face and neck. The lack of informati

23. Polyclonal endemicity of Pseudomonas aeruginosa in a teaching hospital from Brazil: molecular typing of decade-old strains
Pseudomonas aeruginosa infections cause significant mortality and morbidity in health care settings. Strategies to prevent and control the emergence and spread of P. aeruginosa within hospitals involve implementation of barrier methods and antimicrobial stewardship programs. However, there is still much debate over which of these measures holds the utmost im

24. Consequências da barragem eclusa do Canal São Gonçalo para a ictiofauna do sistema Patos-Mirim / Consequences of the São Gonçalo channel s dam-lock to the ichthyofauna of the Patos-Mirim system
The present study aimed to investigate the consequences of the São Gonçalo channel dam-lock in the structure of the marine, estuarine and freshwater fish assemblies that inhabit the Patos-Mirim lagoon system. The study area was the São Gonçalo channel that connects the Patos Lagoon with the Mirim Lagoon. Sampling took place monthly during years 2005 (12
