Autophagy in the retinal neurovascular unit: New perspectives into diabetic retinopathy 视网膜神经血管单元自噬:糖尿病视网膜病变的新视角

open access: yesJournal of Diabetes, Volume 15, Issue 5, Page 382-396, May 2023., 2023
HighlightsAutophagy is closely related to retinal neurovascular units in diabetes retinopathy. Different cells participate in the occurrence and development of diseases through autophagy, and targeted autophagy may be a new direction of treatment in the future. Emphasized the close relationship between diabetic retinopathy (DR) and autophagy Summarized

“互联网+”智慧能源的再认识:基于熵视域 [PDF]

open access: yes全球能源互联网, 2023
“互联网+智慧能源”(即能源互联网)的发展理念,集中体现着数字化技术对能源系统的设计、运行和发展的全局优化。从能源系统热力学熵和信息系统信息熵的理论及视域,阐释能源互联网综合能源系统及其对应能源物联网的熵增与熵减机制。首先,在熵视域下揭示能源互联网所体现出的信息熵与热力学熵之间的内在关联,即通过信息的引入充分激发能量系统的自组织性,减少能源网络的无序程度。同时,以能源互联网范畴中的多能互补综合能源系统和数字孪生能源物联网为对象,以熵理论揭示信息物理融合系统中信息流与能量流的协同作用 ...
