The depth of pseudotachylyte formation from detailed thermochronology and constraints on coseismic stress drop variability [PDF]

, 2012
Pseudotachylytes are accepted as recording paleo-seismicity in the rock record. However, the interpretation of the mechanics of faulting based on pseudotachylyte generation is often hindered because the depth at which they form is poorly constrained ...

Effect of Deviatoric Stress on Deformation Energy of Tectonic Coal: A Modified Energy Model Considering Nonlinearity

Energy Science & Engineering
The deformation energy stored in soil‐like tectonic coal plays a critical role in coal and gas outbursts. Unlike hard rocks, tectonic coal exhibits pronounced stress–strain nonlinearity, invalidating traditional elastic energy models.

Tectonic stress controls saucer-shaped sill geometry

, 2020
Saucer-shaped sills are common in sedimentary basins worldwide. The saucer shape relates to asymmetric stress distributions at the sill-tip during intrusion caused by bending of the overburden.

Lipopolysaccharide, high glucose and saturated fatty acids induce endoplasmic reticulum stress in cultured primary human adipocytes : salicylate alleviates this stress [PDF]

, 2010
Recent findings indicate that endoplasmic reticulum (ER) stress is significantly increased in adipose tissue of obese human subjects and is critical to the initiation and integration of pathways of inflammation and insulin action.
