Dynamic contact angle (DCA) and adhesion tension relaxation (ATR) for poly vinyl alkylate)s (PVA1s) were measured.
Stress remains tensile throughout during deposition and during relaxation, promoting film adhesion by preventing blisters.
This is explained by improved interfacial adhesion and associated slower chain relaxation dynamics.
It is shown that such stresses in ultra-low-k-based interconnect structures can experience relaxation either through interfacial adhesion failure or through the compliance of the porous dielectrics.
PAR2 activation reportedly causes blood vessel relaxation, increased vascular permeability, leukocyte adhesion [18], and release of pro-inflammatory cytokines (e.g. IL-1β, IL-6, IL-8, TNF-α) and Intracellular Cell Adhesion Molecules-1 (ICAM-1) from human blood monocytes [19], [20].
Could the authors more directly perturb the forces exerted on focal adhesions by vsf, e.g. with local relaxation of tension by laser ablation or local increase in tension by pulling on the cell (like in Riveline et al for instance)?
The combining effect of altered vascular relaxation, altered blood flow distribution, increased leucocyte adhesion and decreased coagulation modulation should significantly contribute to microcirculatory heterogeneity and lowered perfusion.
Residual stress relaxation in the polysilicon diaphragm and prevention of adhesion in the sensor cavity are carried out in the process of the sensor fabrication.
These responses are the composite effect of the typical timescales associated with internal and external stresses, the turnover of cytoskeletal proteins and relaxation times of cytoskeletal networks, and the regulation of intercellular adhesion, among other factors.
