Oligomerization and phase separation in globular protein solutions.
We have chemically crosslinked a globular protein, gamma IIIb-crystallin, to produce a system of well-defined oligomers: monomers, dimers, trimers and a mixture of higher n-mers. Gel electrophoresis, size exclusion chromatography, quasielastic light scattering spectroscopy, and electrospray ionization mass spectrometry were used to characterize the oligomers formed. The liquid-liquid phase sepa...
متن کاملPhase separation driven by surface diffusion: a Monte Carlo study.
We propose a kinetic Ising model to study phase separation driven by surface diffusion. This model is referred to as Model S, and consists of the usual Kawasaki spin-exchange kinetics (Model B) in conjunction with a kinetic constraint. We use multispin coding techniques to develop fast algorithms for Monte Carlo simulations of Models B and S. We use these algorithms to study the late stages of ...
متن کاملmodeling loss data by phase-type distribution
بیمه گران همیشه بابت خسارات بیمه نامه های تحت پوشش خود نگران بوده و روش هایی را جستجو می کنند که بتوانند داده های خسارات گذشته را با هدف اتخاذ یک تصمیم بهینه مدل بندی نمایند. در این پژوهش توزیع های فیزتایپ در مدل بندی داده های خسارات معرفی شده که شامل استنباط آماری مربوطه و استفاده از الگوریتم em در برآورد پارامترهای توزیع است. در پایان امکان استفاده از این توزیع در مدل بندی داده های گروه بندی ...
Texturising by phase separation.
The most common food processing operations, thermal and mechanical treatments, both affect phase state and texture of foods. The phase separation threshold for food biopolymer mixtures is usually below their concentrations characteristically found in food. Phase-separation underpins texturisation processes during food processing and digestion. The distribution of water between the phases, the a...
متن کاملMechanically-driven phase separation in a growing bacterial colony.
Secretion of extracellular polymeric substances (EPSs) by growing bacteria is an integral part of forming biofilm-like structures. In such dense systems, mechanical interactions among the structural components can be expected to significantly contribute to morphological properties. Here, we use a particle-based modeling approach to study the self-organization of nonmotile rod-shaped bacterial c...
