An Adipocyte MKK3–p38β Axis Preserves Insulin Responsiveness in Mice and Is Reciprocally Altered in Human Obesity

Advanced Science, EarlyView.
The adipocyte MKK3–p38β axis emerges as an adaptive stress‐response pathway during obesity. Human visceral adipose tissue analyses, adipocyte‐specific mouse models, and primary adipocytes show that the MKK3–p38β axis supports insulin responsiveness by restraining p70S6K‐dependent inhibitory IRS1 feedback and preserving AKT–GLUT4 signaling. This pathway

Physics‐Embedded Neural Network: A Novel Approach to Design Polymeric Materials

Advanced Science, EarlyView.
Traditional black‐box models for polymer mechanics rely solely on data and lack physical interpretability. This work presents a physics‐embedded neural network (PENN) that integrates constitutive equations into machine learning. The approach ensures reliable stress predictions, provides interpretable parameters, and enables performance‐driven, inverse ...

Highly Flexible and Conformable ZnO/FeGa Magnetoelectric Heterostructures for Skin wound Healing

Advanced Science, EarlyView.
The magnetic field‐induced electric field generated by a highly flexile ZnO(piezoelectric)/FeGa(magnetostrictive) magnetoelectric heterostructure embedded in the low Young's modulus elastomer PDMS has been used to stimulate the wound healing processes.

A discussion of some concepts in thermal aging test-thermal aging and thermal breakdown

ICSD'98. Proceedings of the 1998 IEEE 6th International Conference on Conduction and Breakdown in Solid Dielectrics (Cat. No.98CH36132), 2002
Based on the experimental and analytical research results, the thermal stress preprocess and its performance in a thermal aging test should be divided into two distinct physical phases: thermal aging (TA) and thermal breakdown (TB). This paper presents firstly the definitions of TA, TB, and some related concepts in a thermal aging test for winding ...

Thermal aging of polychloroprene

Journal of Polymer Science, 1961
AbstractThe aging of polychloroprene has been studied at normal and elevated temperatures in air, in oxygen, and in nitrogen. A comparison of the molecular weight distribution curves for fresh specimens and for specimens aged under various conditions showed that on aging the polymer becomes heterogeneous.

Impact of Ageing on Thermal Efficiency of Solar Thermal Collectors

2008
Today it is common practice to calculate the performance of solar thermal systems or solar collectors based on the results of a thermal performance test carried out with a new solar collector. However, for an integral assessment of solar thermal collectors and systems, it is necessary to consider the change of performance with time due to degradation ...

Thermally-Induced Cutaneous Vasodilatation in Aging

Journal of Gerontology, 1993
A decrease in heat-induced cutaneous vasodilatation has been implicated as the cause of increased heat stress in the elderly. We used laser Doppler techniques to study the skin blood flow response to local heat in 82 healthy volunteers. There were 39 young volunteers, mean age 29 +/- 1, and 43 elderly volunteers, mean age 76 +/- 1.
