The physical consequences of sperm gigantism
Jasmin Imran Alsous, Brato Chakrabarti, Bryce Palmer +1
The male fruit fly produces ~1.8 mm long sperm, thousands of which can be stored until mating in a ~200 micron sac, the seminal vesicle. While the evolutionary pressures driving su…
Smooth-Rigid-Body Contact as a ReLCP: A Recursively Generated Linear Complementarity Problem
Bryce Palmer, Hasan Metin Aktulga, Tong Gao
This paper reformulates complementarity-based time-stepping for frictionless nonsmooth contact between smooth rigid bodies as a recursively generated linear complementarity problem…
Correlations, mean-field limits, and transition to the concentrated regime in motile particle suspensions
Bryce Palmer, Scott Weady, Michael O'Brien +2
Suspensions of swimming particles exhibit complex collective behaviors driven by hydrodynamic interactions, showing persistent large-scale flows and long-range correlations. While…
Mechanics and morphology of proliferating cell collectives with self-inhibiting growth
Scott Weady, Bryce Palmer, Adam Lamson +3
We study the dynamics of proliferating cell collectives whose microscopic constituents' growth is inhibited by macroscopic growth-induced stress. Discrete particle simulations of a…
OpenRAND: A Performance Portable, Reproducible Random Number Generation Library for Parallel Computations
Shihab Shahriar Khan, Bryce Palmer, Christopher Edelmaierd +1
We introduce OpenRAND, a C++17 library aimed at facilitating reproducible scientific research through the generation of statistically robust and yet replicable random numbers. Open…
Hydrodynamic instabilities and collective dynamics in activity-balanced pusher-puller mixtures
Bryce Palmer, Wen Yan, Tong Gao
Microorganisms living in microfluidic environments often form multi-species swarms, where they can leverage collective motions to achieve enhanced transport and spreading. Neverthe…
