This study reported the multi-component decaying behavior on high-b-value diffusion-weighted MR images. Signal intensity was measured in different regions of the brain. Results showed that gray matter and cerebrospinal fluid exhibited single exponential decaying characteristics while multi-component decaying behavior was observed in some white matter areas with complicated neural fiber orientat...

The interplay of adhesion and phase separation is studied theoretically for two-component membranes that can phase separate into two fluid phases such as liquid-ordered and liquid-disordered phases. Many adhesion geometries provide two different environments for these membranes and then partition the membranes into two segments that differ in their composition. Examples are provided by adhering...

The structure of the ripple phase of phospholipid membranes remains poorly understood in spite of a large number of theoretical studies, with many experimentally established structural features of this phase unaccounted for. In this article we present a phenomenological theory of phase transitions in single- and two-component achiral lipid membranes in terms of two coupled order parameters: a s...
