Regulation of the Heat-Shock Response [PDF]
Plant Physiology, 1998 The heat-shock response is a conserved reaction of cells and organisms to elevated temperatures (heat shock or heat stress). Whereas severe heat stress leads to cellular damage and cell death, sublethal doses of heat stress induce a cellular response, the heat-shock response, which (a ...

A Thermal Actuated Bistable Structure for Generating On-Chip Shock Loads
Micromachines, 2022 In this paper, we propose a bistable shock structure based on the thermal actuation principle, which overcomes the response time limitation of heating and cooling in typical thermal actuators and enables a rapid release of energy.

Bacterial Cold Shock Responses
Science Progress, 2003 As a measure for molecular motion, temperature is one of the most important environmental factors for life as it directly influences structural and hence functional properties of cellular components. After a sudden increase in ambient temperature, which is termed heat shock, bacteria respond by expressing a specific set of genes ...

Transient intracellular acidification regulates the core transcriptional heat shock response
eLife, 2020 Heat shock induces a conserved transcriptional program regulated by heat shock factor 1 (Hsf1) in eukaryotic cells. Activation of this heat shock response is triggered by heat-induced misfolding of newly synthesized polypeptides, and so has been thought ...

The Response of Normal Shocks in Diffusers [PDF]
AIAA Journal, 1983 The frequency response of a normal shock in a diverging channel is calculated for application to problems of pressure oscillations in ramjet engines. Two limits of a linearized analysis arc discussed: one represents isentropic flow on both sides of a shock wave; the other may be a crude appr'l'I;imation to the influence of flow separation induced hy

Atomic insights into the quasi-elastic response in shock reloading of shocked metals
Results in Physics, 2021 The quasi-elastic response has drawn much attention as an interesting phenomenon in physics of shock wave. It has been revealed that heterogeneity features such as defects on the mesoscale play important roles in the quasi-elastic response of shocked ...
