Programmable Multifunctional Bistable Structures for Energy Transfer and Dissipation

open access: yesAdvanced Science, EarlyView.
Utilizing the energy conversion characteristics of asymmetric bistable beams, this study develops a programmable multifunctional system composed of multiple bistable beams for energy transfer and dissipation. The high energy density enables the system to demonstrate potential in transient scenarios such as target delivery and shock absorption ...

A Statistical Mechanics Model to Decode Tissue Crosstalk During Graft Formation

open access: yesAdvanced Science, EarlyView.
We introduce a statistical mechanics framework to decode the genomic crosstalk governing plant grafting. By integrating evolutionary game theory with transcriptomics, we reconstruct idopNetworks (informative, dynamic, omnidirectional, and personalized networks) that map scion–rootstock interactions.

Adriamycin-induced podocyte injury via the Sema3A/TRPC5/Rac1 pathway

open access: yesFrontiers in Medicine
Podocytopathies encompass kidney diseases where direct or indirect podocyte injury leads to proteinuria or nephrotic syndrome. Although Semaphorin3A (Sema3A) is expressed in podocytes and tubular cells in adult mammalian kidneys and has a common effect ...
