The role of body flexibility in stroke enhancements for finite-length undulatory swimmers in viscoelastic fluids [PDF]
, 2016 The role of passive body dynamics on the kinematics of swimming micro-organisms in complex fluids is investigated. Asymptotic analysis of small amplitude motions of a finite-length undulatory swimmer in a Stokes-Oldroyd-B fluid is used to predict shape changes that result as body elasticity and fluid elasticity are varied. Results from the analysis are

Global weak solutions to a 3D/3D fluid-structure interaction problem including possible contacts [PDF]
arXiv, 2023 In this paper, we study an interaction problem between a $3D$ compressible viscous fluid and a $3D$ nonlinear viscoelastic solid fully immersed in the fluid, coupled together on the interface surface. The solid is allowed to have self-contact or contact with the rigid boundary of the fluid container. For this problem, a global weak solution with defect

Dynamic Many-Body Theory. II. Dynamics of Strongly Correlated Fermi Fluids
, 2010 We develop a systematic theory of multi-particle excitations in strongly interacting Fermi systems. Our work is the generalization of the time-honored work by Jackson, Feenberg, and Campbell for bosons, that provides, in its most advanced implementation,

Methylation Markers for the Identification of Body Fluids and Tissues from Forensic Trace Evidence
PLoS ONE, 2016 The identification of body fluids is an essential tool for clarifying the course of events at a criminal site. The analytical problem is the fact that the biological material has been very often exposed to detrimental exogenous influences.

Voronoi Glass-Forming Liquids : A Structural Study
, 2017 We introduce a new theoretical model of simple fluid, whose interactions, defined in terms of the Voronoi cells of the configurations, are local and many-body. The resulting system is studied both theoretically and numerically.

Smooth solutions for motion of a rigid body of general form in an incompressible perfect fluid [PDF]
arXiv, 2012 In this paper, we consider the interactions between a rigid body of general form and the incompressible perfect fluid surrounding it. Local well-posedness in the space $C([0, T); H_s)$ is obtained for the fluid-rigid body system.

Ground state of a polydisperse electrorheological solid: Beyond the dipole approximation
, 2002 The ground state of an electrorheological (ER) fluid has been studied based on our recently proposed dipole-induced dipole (DID) model. We obtained an analytic expression of the interaction between chains of particles which are of the same or different ...

On the motion of rigid bodies in a perfect fluid [PDF]
arXiv, 2019 We consider the problem of motion of several rigid bodies immersed in a perfect compressible fluid. Using the method of convex integration we establish the existence of infinitely many weak solutions with {\it a priori} prescribed motion of rigid bodies.
