Forces and torques on rotating spirochete flagella.
Spirochetes are a unique group of motile bacteria that are distinguished by their helical or flat-wave shapes and the location of their flagella, which reside within the tiny space between the bacterial cell wall and the outer membrane (the periplasm). In Borrelia burgdorferi, rotation of the flagella produces cellular undulations that drive swimming. How these shape changes arise due to the fo...
متن کاملExpressions for forces and torques in molecular simulations using rigid bodies
Abstract Expressions for intermolecular forces and torques, derived from pair potentials between rigid nonspherical units, are presented. The aim is to give compact and clear expressions, which are easily generalised, and which minimise the risk of error in writing molecular dynamics simulation programs. It is anticipated that these expressions will be useful in the simulation of liquid crystal...
متن کاملMicroscopic Calculation of Spin Torques and Forces
Spin torques, that is, effects of conduction electrons on magnetization dynamics, are calculated microscopically in the first order in spatial gradient and time derivative of magnetization. Special attention is paid to the so-called β-term and the Gilbert damping, α, in the presence of electrons’ spin-relaxation processes, which are modeled by quenched magnetic impurities. Two types of forces t...
متن کاملOptical Forces and Torques Acting on Non-spherical Metallic Nanoparticles
Metallic nanoparticles (NPs) are nowadays used in various areas of biology, chemistry or physics, e.g. they are used as a heat source causing hybridization of DNA or probes for surface enhanced Raman spectroscopy. Focused laser beams, so-called optical tweezers [1], are widely used to manipulate dielectric particles or even living cells. Optical tweezers may be used as well to manipulate metall...
متن کاملWorn Tool Forces Based on Ploughing Stresses
Recent work in modeling of the ploughing mechanism in basic metal machining may provide a means of estimating the additional forces to be expected when cutting with a worn tool. The results predict the rubbing stresses due to the finite radius of an unworn tool edge. Since an unworn tool can be thought of as a worn tool with a wear land width VB = 0, these stresses can make up part of a strateg...
