Abstract Background: Acellular tubular artery scaffolds offer structural support for vascular regeneration but are inherently limited by poor anticoagulant properties, which increases the risk of thrombus formation following implantation. This thrombogenicity remains a major obstacle to their clinical application, particularly in small-diameter vascular grafts. Methods: To address this challenge, the present study investigates the use...

Abstract This article tackles the ill-posed challenge of solving a nonlinear heat transfer equation in backward form. Traditional regularization methods (Tikhonov, quasi-reversibility, quasi-boundary value, truncation, etc.) exist, but we introduce a novel approach based on nonlocal diffusion equations with a rescaled convolution kernel. We will provide error estimates and demonstrate the accuracy of this technique...

Abstract This study investigates and compares the characteristics and potential sources of carbonaceous aerosols in fine particulate matter (PM2.5) between urban and suburban areas of Hanoi. Daily samples were collected at two sites in Hanoi, Vietnam, including HUCE (urban) and Thuong Tin (suburban), during June, July, and August 2024, corresponding to the summer period in...
