Interatomic force in systems with multibody interactions.
The system of particles (atoms) interacting via multibody interatomic potential of general form is considered. Possible variants of partition for the total force acting on a single particle into pair contributions are discussed. Two definitions for the force acting between a pair of particles are compared. The forces coincide only if the particles interact via pair or embedded-atom potentials. ...
متن کاملForce Measurement Enabling Precise Analysis by Dynamic Force Spectroscopy
Dynamic force spectroscopy (DFS) makes it possible to investigate specific interactions between two molecules such as ligand-receptor pairs at the single-molecule level. In the DFS method based on the Bell-Evans model, the unbinding force applied to a molecular bond is increased at a constant rate, and the force required to rupture the molecular bond is measured. By analyzing the relationship b...
متن کاملDynamic Measurement of Valve Lift Force
The paper describes tests carried out on disc valves in which the valve seat was withdrawn from the valve wh).le a pressure difference existed across the valve. Simultaneous measurements were made of the force on the valve, the pressure in the plenum chamber and the displacement of the seat from the valve. Force measurements are compared with values of force measured during continuous flow cond...
متن کاملNon-toxic antimicrobials that evade drug resistance
Drugs that act more promiscuously provide fewer routes for the emergence of resistant mutants. This benefit, however, often comes at the cost of serious off-target and dose-limiting toxicities. The classic example is the antifungal amphotericin B (AmB), which has evaded resistance for more than half a century. We report markedly less toxic amphotericins that nevertheless evade resistance. They ...
متن کاملmalWASH: Washing Malware to Evade Dynamic Analysis
Hiding malware processes from fingerprinting is challenging. Current techniques like metamorphic algorithms and diversity generate different instances of a program, protecting it against static detection. Unfortunately, all existing techniques are prone to detection through behavioral analysis – a runtime analysis that records behavior (e.g., through system call invocations), and can detect exe...
