We discuss the phase behavior and in particular crystallization of a model globular protein (beta-lactoglobulin) in solution in the presence of multivalent electrolytes. It has been shown previously that negatively charged globular proteins at neutral pH in the presence of multivalent counterions undergo a ‘‘re-entrant condensation (RC)’’ phase behavior (Zhang et al., Phys. Rev. Lett., 2008, 10...

The phase unwrapping problem is always solved in the hypothesis that the variation rate of the phase function to be reconstructed is not too high, i.e. the phase fringes are not too dense, for significant large areas. There exist cases where this assumption is not true and the classical phase unwrapping approaches fail. For example, Synthetic Aperture Radar (SAR) differential interferometric me...

BACKGROUND Displacement Encoding with Stimulated Echoes (DENSE) encodes displacement into the phase of the magnetic resonance signal. Due to the stimulated echo, the signal is inherently low and fades through the cardiac cycle. To compensate, a spiral acquisition has been used at 1.5T. This spiral sequence has not been validated at 3T, where the increased signal would be valuable, but field inh...

Phase separation simulation study related to cellulose acetate-water-acetone has been done. Results show that porous asymmetric and symmetric membranes can be produced by changing the nonsolvent concentration or by the drying conditions without altering the polymer content using dry-casting process. Dry-casting process is the process in which complete evaporation of solvent and nonsolvent takes...

We describe the compression of a water-soluble polymer brush which undergoes compressioninduced phase transitions. The solution behavior of the polymer comprising the brush is described using the de Gennes “n-cluster” model which predicts a region of coexistence between dense and dilute phases. We show that compression of the brush can induce the formation of a dense coexisting phase or the eli...

the submodules with the property of the title ( a submodule $n$ of an $r$-module $m$ is called strongly dense in $m$, denoted by $nleq_{sd}m$, if for any index set $i$, $prod _{i}nleq_{d}prod _{i}m$) are introduced and fully investigated. it is shown that for each submodule $n$ of $m$ there exists the smallest subset $d'subseteq m$ such that $n+d'$ is a strongly dense submodule of $m$...

We introduce a microscopic model for particles with dissimilar patches which displays an unconventional "pinched" phase diagram, similar to the one predicted by Tlusty and Safran in the context of dipolar fluids [Science 290, 1328 (2000)]. The model-based on two types of patch interactions, which account, respectively, for chaining and branching of the self-assembled networks-is studied both nu...

We present a semianalytical free-energy model aimed at characterizing the thermodynamic properties of dense fluid helium, from the low-density atomic phase to the high-density fully ionized regime. The model is based on a free-energy minimization method and includes various different contributions representative of the correlations between atomic and ionic species and electrons. This model allo...

MRI provides a valuable tool for noninvasive evaluation of myocardial wall motion. Recently, multi-phase 2D DENSE MRI was developed to quantify cardiac strain in mice at high spatial and temporal resolution [1, 2]. DENSE methods for 3D displacement encoding have also been investigated [3]. Typically, these methods entail multiple acquisitions that are time consuming. In this project, we aimed t...
