Activation volume in superpressed glass-formers. [PDF]
AbstractIn pressurized glass-forming systems, the apparent (changeable) activation volume Va(P) is the key property governing the previtreous behavior of the structural relaxation time (τ) or viscosity (η), following the Super-Barus behavior: $${\boldsymbol{\tau }}{\boldsymbol{(}}{\boldsymbol{P}}{\boldsymbol{)}}{\boldsymbol{,}}{\boldsymbol{\eta ...

Activation volume of selected liquid crystals in the density scaling regime. [PDF]
In this paper, we demonstrate and thoroughly analyze the activation volumetric properties of selected liquid crystals in the nematic and crystalline E phases in comparison with those reported for glass-forming liquids.

Transition-State Compressibility and Activation Volume of Transient Protein Conformational Fluctuations [PDF]
Proteins are dynamic entities that intermittently depart from their ground-state structures and undergo conformational transitions as a critical part of their functions.

Strong obstacles can greatly impede the motion or transmission of dislocations, which can be reflected by strain rate sensitivity and activation volume. In this study, the strain rate sensitivity and activation volume of overaged Al-Zn-Mg-Cu alloys with ...

Active Volume Regulation in Adhered Cells [PDF]
Significance Living cells regulate their volume using a diverse set of mechanisms to maintain their structural and functional integrity. The most widely used mechanism to control cell volume is active ion transport. Recent experiments on adhered cells reveal that their volume is significantly reduced as their basal area is increased ...

The Effect of Strain Rate on the Deformation Processes of NC Gold with Small Grain Size
The strength of nanocrystalline (NC) metal has been found to be sensitive to strain rate. Here, by molecular dynamics simulation, we explore the strain rate effects on apparent Young’s modulus, flow stress and grain growth of NC gold with small size. The

Stress relaxation behavior of low carbon steel at different temperatures
In this paper, the stress relaxation behavior of Q235 with the initial tensile stress of 70, 85 and 100 MPa were investigated at different temperature. Based on the thermal activation theory, the stress relaxation model of Q235 steel was established, and

Topological Active Volumes [PDF]
The topological active volumes (TAVs) model is a general model for 3D image segmentation. It is based on deformable models and integrates features of region-based and boundary-based segmentation techniques. Besides segmentation, it can also be used for surface reconstruction and topological analysis of the inside of detected objects. The TAV structure
