The Mediterranean damselfish Chromis chromis is a species with a broad distribution found both in the Mediterranean Sea and Eastern Atlantic as far south as the coast of Angola. We hypothesized that the species may have significant functional morphological plasticity to adapt along a gradient of environmental conditions. It is a non-migratory zooplanktivorous species and spends the daytime sear...

We introduce a new computational method for embedding Lagrangian sink particles into an Eulerian calculation. Simulations of gravitational collapse or accretion generally produce regions whose density greatly exceeds the mean density in the simulation. These dense regions require extremely small time steps to maintain numerical stability. Smoothed particle hydrodynamics (SPH) codes approach thi...

First data reported by the STAR Collaboration at RHIC [1] has a significant meaning that the observed large magnitude of elliptic flow for charged hadrons is consistent with hydrodynamic predictions [2]. This suggests that large pressure possibly in the partonic phase is built at the early stage (τ ∼ 0.6 fm/c) in Au+Au collisions at sNN = 130 and 200 GeV. This situation at RHIC is in contrast t...

We discuss the underlying relativistic physics that causes neutron stars to compress and collapse in close binary systems as has been recently observed in numerical (311)-dimensional general relativistic hydrodynamic simulations. We show that compression is driven by velocity-dependent relativistic hydrodynamic terms which increase the self-gravity of the stars. They also produce fluid motion w...

W e introduce a software package integrated with the molecular dynamics software LAMMPS for fluctuating hydrodynamics simulations of fluid-structure interactions subject to thermal fluctuations. The package is motivated to provide dynamic thermostats to extend implicit-solvent coarse-grained (IS-CG) models by incorporating kinetic contributions from the solvent to facilitate their use in a wide...

Submitted for the MAR13 Meeting of The American Physical Society Hamiltonian Formulation of the Hydrodynamics with Quantum Anomalies GUSTAVO MONTEIRO, ALEXANDER ABANOV, Stony Brook University — The hydrodynamic limit of a charged massless chiral spinor under the presence of gauge field in 3 dimensions is consider in [1]. For this system, global gauge symmetry is anomalous. In order to satisfy t...

We have developed a new computer code, RAM, to solve the conservative equations of special relativistic hydrodynamics (SRHD) using adaptive mesh refinement (AMR) on parallel computers. We have implemented a characteristic-wise, finite difference, weighted essentially non-oscillatory (WENO) scheme using the full characteristic decomposition of the SRHD equations to achieve fifth order accuracy i...

where lmicro is a characteristic scale of microscopic processes in the system (e.g. a correlation length), and L is a typical size of the system. Hydrodynamic description becomes unreliable when the inequality (1) is not satisfied. Schwarzschild black holes do not correspond to any hydrodynamic regime in a (hypothetical) holographicaly dual description because in that case L ∼ 1/T ∼ lmicro. We ...
