Existing point cloud semantic segmentation approaches do not perform well on details, especially for the boundary regions.However, supervised-learning-based methods depend on costly artificial annotations for performance improvement.In this paper, we bridge this gap by designing a self-supervised pretext task applicable to point clouds.Our main inn
Introduction: Opiate (including heroin) use prevalence is 1.2% of the world population according to the last report of UNOCD.In Iran about 2 million people of population are drug abusers.Heroin reduces gastric motility and prolongs gastric emptying time and it can cause gastric dilation which can be a reason for gastric ischemia.Gastric ischemia is
Proteins for elongation of very long-chain fatty acids (ELOVLs) are critical for the synthesis of long-chain polyunsaturated fatty acids (LC-PUFAs), and they are one group of the rate-limiting enzymes responsible for the initial condensation reaction within the fatty acid elongation.Elovl8 is a newly identified member of the ELOVL protein family, a
