Brain tumors are a leading cause of mortality worldwide, with early and accurate diagnosis being essential for effective treatment. Although Deep Learning (DL) models offer strong performance in tumor detection segmentation using MRI, their black-box nature hinders clinical adoption due to lack interpretability. We present hybrid AI framework that integrates 3D U-Net Convolutional Neural Network MRI-based radiomic feature extraction. Dimensionality reduction is performed machine learning, an...
Among all the tumors that can affect brain, gliomas are most frequent, thus is important to get a correct characterization and delimitation of this malformation provide best diagnosis treatment possible. Nevertheless, there some issues when dealing with segmenting tumors, it be long tedious labor, which makes prone mistakes. To solve those problems, several techniques were proposed, including automatic semiautomatic segmentation. In work, we propose use U-net architecture-based deep neural...
This article analyses the character of XIXth c. chilean liberalism. On one hand, it was successful in placing economy into world period and modernization enfraestructure. other although there were important improvements related to institutional framework economic activities, no changes social structure. In comparative perspective, author stresses need look experiences past for better understanding present.
In this study, we applied an evolutionary perspective to analyze the relationship between aggressiveness, academic performance, and sociality in a population of 528 adolescents both sexes. men, expect physical aggression (PA) be negative predictors performance. However, women, PA would predictor positive one. Our results report association performance As expected, social effect derived from use seems different for each sex, where men could display rebellious attitude increase chances finding...
