We study the lateral and transverse diffusion of amphiphiles in two-component bilayer membranes, using a coarse-grained model for amphiphilic molecules and combined Monte Carlo-Molecular Dynamics simulations. Membrane structural properties, such as the mean thickness, are also measured. The dependence of...
The crack band model, which is easier to implement and is used in commercial codes (e.g., DIANA, SBETA) [49], is, for localized cracking or fracture, nearly equivalent to the cohesive crack model ([BP], [97]), provided that the effective (average) transverse strain in the crack band...
The extent to which the VS signal looks like a reward prediction error, rather than a simple coding of reward, depends on the strength of connection (measured by diffusion MRI tractography) between the VS and the dopaminergic midbrain [44]. Collectively, these studies demonstrate its key role ...
sequence, based on marked changes in seismicity rates and on measured peak ground velocities (PGVs) and peak dynamic strains, both exhibiting local maxima in their map distributions. The causes of the delayed triggering may be related to the well-known geothermal field in central/north Evia and ...
This suggests an additional sebum effect may be specific to ZnPT which could be explained by its propensity to undergo molecular transformations.;High lateral to transverse diffusion ratios signify that ZnPT is able to migrate laterally on the skin surface to exert biocidal activity prior to ...
Diffusion tractography can also detect significant white matter changes (i.e., reduced fractional anisotropy and increased mean diffusivity) along thalamo-cortical connections from the mediodorsal thalamic nucleus in chronic schizophrenic patients (Oh et al., 2009) but not in first-episode psychosis (...
Identifying structure–function correspondences is a major goal among biologists, cognitive neuroscientists, and brain mappers. Recent studies have identified relationships between performance on cognitive tasks and the presence or absence of small, shallow indentations, or sulci, of the human brain. Buil...
This has motivated the recent diffusion of works in the literature, focusing on the mechanical behavior of FG and/or homogenous nano-sized beams. A nonlocal elasticity theory, for example, was suggested by Peddieson et al. [90] to study the nonlocal behavior of Benoulli/Euler beams. In ...
Since each GUV forms a closed system with negligible lipid exchange between GUVs during cooling, and since diffusion of the bilayer components is restricted to the two-dimensional plane, diffusion may be the rate-limiting step in crystallization, promoting the dendritic growth of bolapolyphile-DPPC...
(8) η∇u · n = 0 on ΓBC (9) In addition, the following convection–diffusion equation is for the concentration c of the dissolved substances in the fluid: u · ∇c = ∇ · (D∇c) in Ω (10) where c and D are, respectively, the concentration and the diffusion ...
