Applied Sciences, 2018 We investigated particulate flows by coupling simulations of the three-dimensional incompressible Navier–Stokes equation with the immersed boundary method (IBM). The results obtained from the two-way coupled simulation were compared with those of the one-

Peroxidasin enables melanoma immune escape by inhibiting natural killer cell cytotoxicity
Molecular Oncology, EarlyView.Peroxidasin (PXDN) is secreted by melanoma cells and binds the NK cell receptor NKG2D, thereby suppressing NK cell activation and cytotoxicity. PXDN depletion restores NKG2D signaling and enables effective NK cell–mediated melanoma killing. These findings identify PXDN as a previously unrecognized immune evasion factor and a potential target to improve

Pulsing corals: A story of scale and mixing
Biomath, 2017 Effective methods of fluid transport vary across scale. A commonly used dimensionless number for quantifying the effective scale of fluid transport is the frequency based Reynolds number, Re, which gives the ratio of inertial to viscous forces in a fluid

Immersed, virtually-embedded, boundary slopes
Topology and its Applications, 2000 Let \(M\) be the exterior of the figure eight knot. In this paper the authors prove that every slope with even numerator is realized as the boundary curve of an immersed, incompressible, \(\partial\)-incompressible surfacc in \(M\). This immersed surface is covered by an imbedded, incompressible, \(\partial\)-incompressible surface in some finite ...

Approximate imposition of boundary conditions in immersed boundary methods [PDF]
International Journal for Numerical Methods in Engineering, 2009 AbstractWe analyze several possibilities to prescribe boundary conditions in the context of immersed boundary methods. As basic approximation technique we consider the finite element method with a mesh that does not match the boundary of the computational domain, and therefore Dirichlet boundary conditions need to be prescribed in an approximate way ...

The volume-filtering immersed boundary method
Journal of Computational Physics, 2023 We present a novel framework to deal with static and moving immersed boundaries (IB). In this strategy, called Volume-Filtering Immersed Boundary (VFIB) method, transport equations are derived by filtering the Navier-Stokes equations and accounting for stresses at the solid-fluid interface.

Regularized Stokes Immersed Boundary Problems in Two Dimensions: Well‐Posedness, Singular Limit, and Error Estimates [PDF]
Communications on Pure and Applied Mathematics, 2019 Inspired by the numerical immersed boundary method, we introduce regularized Stokes immersed boundary problems in two dimensions to describe regularized motion of a 1‐D closed elastic string in a 2‐D Stokes flow, in which a regularized δ‐function is used
