The Muller’s Ratchet and Aging
Trends in Genetics, 2020 Aging entails an irreversible deceleration of physiological processes, altered metabolic activities, and a decline of the integrity of tissues, organs, and organ systems. The accumulation of alterations in the genetic and epigenetic spaces has been proposed as an explanation for aging.

Occurrence of plastic collapse under ratcheting due to gravity and seismic loading
Mechanical Engineering Journal, 2022 The most dominant failure mode of piping components under seismic loading is fatigue failure with ratcheting. While it was confirmed via the experimental tests in the past, the Primary stress limit is applied to seismic loading to prevent plastic ...

Ratcheting of Granular Materials [PDF]
Physical Review Letters, 2004 We investigate the quasi-static mechanical response of soils under cyclic loading using a discrete model of randomly generated convex polygons. This response exhibits a sequence of regimes, each one characterized by a linear accumulation of plastic deformation with the number of cycles.

Controlling heat ratchet and flow reversal with simple networks
Physical Review Research, 2023 We investigate ratcheting heat flow in simple networks consisting of a one-dimensional nonlinear chain with a self-coupled loop when the average thermal bias is zero.
