This paper presents a high performance vision-based system with a single static camera for traffic surveillance, for moving vehicle detection with occlusion handling, tracking, counting, and One Class Support Vector Machine (OC-SVM) classification. In this approach, moving objects are first segmented from the background using the adaptive Gaussian Mixture Model (GMM). After that, several geometric features are extracted, such as vehicle area, height, width, centroid, and bounding box. As occlusion is present, an algorithm was implemented to reduce it. The tracking is performed with adaptive Kalman filter. Finally, the selected geometric features: estimated area, height, and width are used by different classifiers in order to sort vehicles into three classes: small, midsize, and large. Extensive experimental results in eight real traffic videos with more than 4000 ground truth vehicles have shown that the improved system can run in real time under an occlusion index of 0.312 and classify vehicles with a global or , , and of up to 98.190%, and an of up to 99.051% for midsize vehicles.

A therapeutic study of JNPL3 mice with chronic treatment from 7-12 months of age inhibited the progression of tau aggregation and improved motor coordination.

Unlabelled: This study aims to create a fatigue recognition system that utilizes electroencephalogram (EEG) signals to assess a driver's physiological and mental state, with the goal of minimizing the risk of road accidents by detecting driver fatigue regardless of physical cues or vehicle attributes. A fatigue state recognition system was developed using transfer learning applied to partial ensemble averaged EEG power spectral density (PSD). The study utilized layer-wise relevance propagation (LRP) analysis to identify critical cortical regions and frequency bands for effective fatigue discrimination.

Objective: To test the safety and efficacy of combination treatment for pleural mesothelioma (PM) with intracavitary cisplatin-fibrin (cis-fib) plus hemithoracic irradiation (IR) applied after lung-sparing surgery in an orthotopic immunocompetent rat model.
Methods: We randomized male F344 rats into 5 groups: cis-fib (n = 9), 10 Gy IR (n = 6), 20 Gy IR (n = 9), cis-fib+10 Gy IR (n = 6), and cis-fib+20 Gy IR (n = 9). Subpleural tumor implantation was performed on day 0 with 1 million syngeneic rat mesothelioma cells (IL45-luciferase).
