Bleeding‐Mimetic Damage‐Detecting and Self‐Healing Modular Skin for Inflatable Structures

open access: yesAdvanced Robotics Research, EarlyView.
A damage‐detecting and self‐healing system inspired by the human bleeding mechanism is developed for inflatable structures, using a liquid conductive elastomeric material enclosed in a small pouch. This material, composed of uncured elastomer, its curing agent, conductive particles, and a dispersant, solidifies only after being exposed to air and ...

NOX2 Contributes to High‐Frequency Outer Hair Cell Vulnerability in the Cochlea

open access: yesAdvanced Science, EarlyView.
This study first identifies NOX2 as a differentially expressed gene related to oxidative damage in the apical and basal turns through single‐cell RNA sequencing. NOX2 gene knockout mitigates OHCs damage caused by neomycin and noise and enhances Nrf2 expression and nuclear translocation.

Nonlinear convection in reaction-diffusion equations under dynamical boundary conditions

open access: yesElectronic Journal of Differential Equations, 2013
We study the blow-up phenomena for positive solutions of nonlinear reaction-diffusion equations including a nonlinear convection term $partial_t u = Delta u - g(u) cdot abla u + f(u)$ in a bounded domain of $mathbb{R}^N$ under the dissipative ...

Noetherian symbolic blow-ups

open access: yesJournal of Algebra, 1991
The following question was raised by Cowsik [Cw]: if P is a prime ideal in a regular local ring (R, n?), is the symbolic Rees ring Rep) := @,120 PC”’ a noetherian ring, where PC”’ is . the n-symbolic power of P (i.e., P’“‘= P”R, n R).

Cathepsin K Aggravates Pulmonary Fibrosis Through Promoting Fibroblast Glutamine Metabolism and Collagen Synthesis

open access: yesAdvanced Science, EarlyView.
CTSK plays a critical role in pulmonary fibrosis. Excessive CTSK accumulation interacts with SNX9 to enhance TGF‐β1‐induced SMAD3 activation and GLS1 expression in fibroblasts, driving glutamine metabolism for collagen biosynthesis and exacerbating pulmonary fibrosis.

A blow up condition for a nonautonomous semilinear system

open access: yesElectronic Journal of Differential Equations, 2006
We give a sufficient condition for finite time blow up of the nonnegative mild solution to a nonautonomous weakly coupled system with fractal diffusion having a time dependent factor which is continuous and nonnegative.
