Biophysics at the coffee shop: lessons learned working with George Oster
Oleg Igoshin, Jing Chen, Jianhua Xing +9
Over the past 50 years, the use of mathematical models, derived from physical reasoning, to describe molecular and cellular systems has evolved from an art of the few to a cornerst…
Swimming speeds of filaments in nonlinearly viscoelastic fluids
Henry C. Fu, Charles W. Wolgemuth, Thomas R. Powers
Many microorganisms swim through gels and non-Newtonian fluids in their natural environments. In this paper, we focus on microorganisms which use flagella for propulsion. We addres…
Kinematics of the swimming of Spiroplasma
Jing Yang, Charles W. Wolgemuth, Greg Huber
\emph{Spiroplasma} swimming is studied with a simple model based on resistive-force theory. Specifically, we consider a bacterium shaped in the form of a helix that propagates trav…
Beating patterns of filaments in viscoelastic fluids
Henry C. Fu, Charles W. Wolgemuth, Thomas R. Powers
Many swimming microorganisms, such as bacteria and sperm, use flexible flagella to move through viscoelastic media in their natural environments. In this paper we address the effec…
Theory of swimming filaments in viscoelastic media
Henry C. Fu, Thomas R. Powers, Charles W. Wolgemuth
Motivated by the swimming of sperm in the non-Newtonian fluids of the female mammalian reproductive tract, we examine the swimming of filaments in the nonlinear viscoelastic Upper…
Dynamic supercoiling bifurcations of growing elastic filaments
Charles W. Wolgemuth, Raymond E. Goldstein, Thomas R. Powers
Certain bacteria form filamentous colonies when the cells fail to separate after dividing. In Bacillus subtilis, Bacillus thermus, and cyanobacteria, the filaments can wrap into co…
