The purpose of this study was to evaluate and compare the mechanical behavior of five nanofilled composites with dentin and enamel shades trough diametral tensile strength and knoop microhardness. 4 Seasons (Ivoclar Vivadent), Esthet X improved (Dentsply), Filtek Supreme (3M), Grandio (Voco) and Palfique Estelite (Tokuyama Dental Corp.) were used in this(More)
The purpose of this study was to evaluate the mechanical behavior of three composites with nanoparticles Filtek Z350 XT (3M ESPE), Esthet X (Dentsply), Grandio (Voco) in enamel and body shades (A2) trough nanohardness, elastic modulus, compressive strength test, flexural strength test, diametral tensile strength, flexural modulus, weight filler content and(More)
Haplotype information has a central role in the understanding and diagnosis of certain illnesses, and also for the evolution studies. Since that type of information is hard to obtain directly, computational methods to infer haplotype from genotype data have received great attention from the computational biology community. Unfortunately, this is a very hard(More)
We collect data from the HIV Resistance Drug Database and, based on CD4+ and viral load measures, together with RNA sequences of the reverse transcriptase and of the protease of the virus, we design models using machine learning techniques MultiLayer Perception (MLP), Radial Basis Function (RBF), and Support Vector Machine (SVM), to predict the patient's(More)
