1. Otobone®: Three-dimensional printed Temporal Bone Biomodel for Simulation of Surgical Procedures
Abstract Introduction The anatomy of the temporal bone is complex due to the large number of structures and functions grouped in this small bone space, which do not exist in any other region in the human body. With the difficulty of obtaining anatomical parts and the increasing number of ear, nose and throat (ENT) doctors, there was a need to create altern

2. Genomic and phylogenetic evidence of VIPER retrotransposon domestication in trypanosomatids
Transposable elements are important residents of eukaryotic genomes and eventually the host can domesticate them to serve cellular functions. We reported here a possible domestication event of the vestigial interposed retroelement (VIPER) in trypanosomatids. We found a large gene in a syntenic location in Leishmania braziliensis, L. panamensis, Leptomanas py

3. Spider species composition in the tree-shrub strata of riparian forests and its microhabitats in southern Brazil
ABSTRACT The composition of the spider fauna of riparian forests is insufficiently known. These forests, adjacent to both aquatic and terrestrial environments, are recognised as having important ecosystem functions. We compare the composition of spider assemblages of four riparian forests in different drainage basins, along with their microhabitats (edges an

4. Searching for convergent evolution in manganese superoxidase dismutase using hydrophobic cluster analysis
There are numerous examples of convergent evolution in nature. Major ecological adaptations such as flight, loss of limbs in vertebrates, pesticide resistance, adaptation to a parasitic way of life, etc., have all evolved more than once, as seen by their analogous functions in separate taxa. But what about protein evolution? Does the environment have a stron

5. Optimizing similarity queries in metric spaces meeting user\ s expectation / Otimização de operações de busca por similaridade em espaços métricos
The complexity of data stored in large databases has increased at very fast paces. Hence, operations more elaborated than traditional queries are essential in order to extract all required information from the database. Therefore, the interest of the database community in similarity search has increased significantly. Two of the well-known types of similarit

6. 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

7. Monitoring sugar cane crops through dtw-based method for similarity search in NDVI time series.
Brazil is an important sugar cane producer, which is the main resource for ethanol production, a renewable source of energy. Due to the strategical importance of this agricultural commodity, it is necessary to improve models that assist the crops monitoring process. Recently, remote sensing images have also been used to crops monitoring. Vegetation index ima

8. Seleção de características por meio de algoritmos genéticos para aprimoramento de rankings e de modelos de classificação / Feature selection by genetic algorithms to improve ranking and classification models
Content-based image retrieval (CBIR) and classification systems rely on feature vectors extracted from images considering specific visual criteria. It is common that the size of a feature vector is of the order of hundreds of elements. When the size (dimensionality) of the feature vector is increased, a higher degree of redundancy and irrelevancy can be obse

9. Stochastic texture analysis for measuring sheet formation variability in the industry
Several continuous manufacturing processes use stochastic texture images for quality control and monitoring. Large amounts of pictorial data are acquired, providing important information about both the materials produced and the manufacturing processes involved. However, it is often difficult to measure objectively the similarity among such industrial stocha

10. Protein structure comparison via contact map alignment / Protein structure comparison via contact map alignment
Proteins are primary components in almost all biological processes in living organisms. It is known that the variety of protein functions is a result of the differences in protein structures. Therefore, understanding and comparing the structure of proteins is a major challenge in modern molecular biology. The structural alignment and comparison of proteins b

11. MHC class I loci of the Bar-Headed goose (Anser indicus)
MHC class I proteins mediate functions in anti-pathogen defense. MHC diversity has already been investigated by many studies in model avian species, but here we chose the bar-headed goose, a worldwide migrant bird, as a non-model avian species. Sequences from exons encoding the peptide-binding region (PBR) of MHC class I molecules were isolated from liver ge

12. A FRAMEWORK FOR THE CONSTRUCTION OF MEDIATORS OFFERING DEDUPLICATION / UM FRAMEWORK PARA A CONSTRUÇÃO DE MEDIADORES OFERECENDO ELIMINAÇÃO DE DUPLICATAS
As Web applications that obtain data from different sources (Mashups) grow in importance, timely solutions to the duplicate detection problem become central. Most existing techniques, however, are based on machine learning algorithms, that heavily rely on the use of relevant, manually labeled, training datasets. Such solutions are not adequate when talking a
