Biophysical Journal, 2014 Following recent observations of large scale correlated motion of chromatin inside the nuclei of live differentiated cells, we present a hydrodynamic theory-the two-fluid model-in which the content of a nucleus is described as a chromatin solution with the nucleoplasm playing the role of the solvent and the chromatin fiber that of a solute. This system

HYDRODYNAMICS OF THE VACUUM [PDF]
International Journal of Modern Physics A, 2006 Hydrodynamics is the appropriate "effective theory" for describing any fluid medium at sufficiently long length scales. This paper treats the vacuum as such a medium and derives the corresponding hydrodynamic equations. Unlike a normal medium the vacuum has no linear sound-wave regime; disturbances always "propagate" nonlinearly.

Biophysical Journal, 2017 The Gram-negative Bdellovibrio bacteriovorus (BV) is a model bacterial predator that hunts other bacteria and may serve as a living antibiotic. Despite over 50 years since its discovery, it is suggested that BV probably collides into its prey at random. It remains unclear to what degree, if any, BV uses chemical cues to target its prey.

Physical Review Letters, 2013 We report the experimental observation of multi-bound-soliton solutions of the nonlinear Schrodinger equation (NLS) in the context of hydrodynamic surface gravity waves. Higher-order N-soliton solutions with N = 2, 3 are studied in detail and shown to be associated with self-focusing in the wave group dynamics and the generation of a steep localized ...

Recent Development in Hydrodynamic and Heat Transfer Characteristics in the Three-phase Fluidized-bed System [PDF]
Engineering and Technology Journal, 2022 Gas–liquid-solid fluidized beds are broadly utilized in the petrochemical, pharmaceutical, refining, food, biotechnology, and environmental industries. Due to complex phenomena, such as the particle-particle, liquid-particle, particle-bubble interactions,

Journal of High Energy Physics, 2013 We construct the hydrodynamics of quantum critical points with Lifshitz scaling. There are new dissipative effects allowed by the lack of boost invariance. The formulation is applicable, in general, to any fluid with an explicit breaking of boost symmetry.

Introduction to hydrodynamics [PDF]
International Journal of Modern Physics E, 2015 Hydrodynamics has been successful in providing a good description of the bulk dynamics in ultra-relativistic heavy ion collisions. In this brief review, we provide basics of the theory of viscous hydrodynamics. Topics covered include derivation of the 2nd order viscous hydrodynamics from the linear response theory and kinetic theory, viscous ...

Frontiers in Marine Science, 2021 This study explored the effects of interactions between waves and current on storm surge in the Pearl River Estuary (PRE) using a fully coupled wave–current model. The model was validated based on in situ observations during the traverse of super typhoon

Physical Review E, 2011 We show by nonequilibrium molecular dynamics simulations that the Navier-Stokes equation does not correctly describe water flow in a nanoscale geometry. It is argued that this failure reflects the fact that the coupling between the intrinsic rotational and translational degrees of freedom becomes important for nanoflows.

Hydrodynamics of resonances [PDF]
Nuclear Physics A, 2011 We derive system of equations describing fluidity of the medium consisting of non-relativistic particles with finite mass-widths. For that we use expressions for the kinetic Noether 4-current and the Noether energy-momentum tensor being conserved provided one uses self-consistent approximations to the gradient expanded Kadanoff-Baym equations.
