A Model of a Buoyancy-Driven Heat Exchanger, with Implications for Optimal Design
Sylvie Bronsard, Charles S. Peskin
In this paper, we introduce a model for a buoyancy-driven, air-to-air heat exchanger. This model, derived from first principles, features a conservative boundary condition at inflo…
State change via one-dimensional scattering in quantum mechanics
Olivia Pomerenk, Charles S. Peskin
This study aims to address the nature of state change, measurement, and probabilistic outcomes in non-relativistic quantum mechanics. We consider a pair of particles that interact…
Convergence of the Immersed Boundary Method for an Elastically Bound Particle Immersed in a 2D Navier-Stokes Fluid Fluid
Alexandre X. Milewski, Charles S. Peskin
The immersed boundary (IB) method has been used as a means to simulate fluid-membrane interactions in a wide variety of biological and engineering applications. Although the numeri…
Muscle Crossbridge Theory With Internal Crossbridge Dynamics
Mengjian Hua, Charles S. Peskin
We describe in this paper a crossbridge model in which an attached crossbridge behaves like a linear spring with a variable rest length. We assume in particular that the rest lengt…
A model for contractile stress fibers embedded in bulk actomyosin networks
Mariya Savinov, Charles S. Peskin, Alex Mogilner
Contractile cytoskeletal structures such as fine actomyosin meshworks and stress fibers are essential force-generators for mechanical phenomena in live cells, including motility, m…
