Based on the thermodynamic concept of a reservoir, we investigate a computational model for interaction with unresolved degrees of freedom (a thermal bath). We assume that a finite restricted system can be modelled by a generalized canonical ensemble, described by a density which is a smooth function of the energy of the restricted system. A thermostat is constructed to continuously perturb the...

We investigated the relations between the yield stress of polar-molecule dominated electrorheological (PM-ER) fluids and the shape of ellipsoidal particles of the fluids. It is found that, when the short axis of an ellipsoidal particle is along an external electric field while the volume of the particle keeps constant, the shorter of the short axis is, the stronger the attraction between the tw...

The paper focuses on the data collected from the mixing of shear thinning non-Newtonian fluids in a cylindrical tank by a Rushton turbine. The data presented are obtained by using Computational Fluid Dynamics (CFD) simulation of fluid flow field in the entire tank volume. The CFD validation data for this study is reported in the research article 'Numerical investigation of hydrodynamic behavior...

Biochemical reactions in crowded fluids have been predicted to differ strongly from those in aqueous solutions. Both excludedvolume interactions with surrounding macromolecules and crowding-induced subdiffusion have been predicted to stabilize complex formation of reaction partners. Here we show that both facets of crowding strongly alter the stochastic opening and closing of a single-stranded ...

In recent years, aptamers have come to replace antibodies in high throughput multiplexed experiments. The aptamer-based biomarker screening technology, which kicked off in 2010, is capable of interrogating thousands of proteins in a very small sample volume. With this new technology, researchers hope to find clinically appropriate biomarkers for a myriad of illnesses by screening human body flu...

A finite-volume method is applied to the numerical simulation of flows of viscoelastic fluids in the benchmark confined-cylinder problem under creeping flow conditions. The fluids are modeled using the Oldroyd-B constitutive equation, the calculation of the polymer stress contribution is carried out using the logconformation methodology [1] and the results are compared with data using the stand...

We study the fingering instability of the interface between two miscible fluids, a colloidal suspension and its own solvent. The temporal evolution of the interface in a Hele-Shaw cell is found to be governed by the competition between the nonlinear viscosity of the suspension and an off-equilibrium, effective surface tension Γe. By studying suspensions in a wide range of volume fractions, ΦC, ...

We present a code for solving the coupled Einstein-hydrodynamics equations to evolve relativistic, selfgravitating fluids. The Einstein field equations are solved in generalized harmonic coordinates on one grid using pseudospectral methods, while the fluids are evolved on another grid using shock-capturing finite difference or finite volume techniques. We show that the code accurately evolves e...

Sepsis is a systemic inflammatory response to severe infection causing significant morbidity and mortality that costs the health care system $20.3 billion annually within the United States. It is well established that fluid resuscitation is a central component of sepsis management; however, to date there is no consensus as to the ideal composition of fluid used for resuscitation. In this review...
