The endoplasmic reticulum (ER) is a site of protein biogenesis in eukaryotic cells. Perturbing ER homeostasis activates stress programs collectively called the unfolded protein response (UPR). The UPR enhances production of ER-resident chaperones and enzymes to reduce the burden of misfolded proteins....
(non-shear) can erroneously predict frictional shear stresses in excess of the flow stress of the material when the normal stresses are large ;To avoid numerical problems with the friction discontinuity Based on an arc-tan function Ft = m Fn * [2/p atan(vr /C)] st = m sn * [2/p ...
