Ratcheting droplet pairs [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2018 Millimetric droplets may be levitated on the surface of a vibrating fluid bath. Eddi et al. [Europhys. Lett. 82, 44001 (2008)] demonstrated that when a pair of levitating drops of unequal size are placed nearby, they interact through their common wavefield in such a way as to self-propel through a ratcheting mechanism.

Ratcheting behavior of Eurofer97 at 550 °C
Nuclear Materials and Energy, 2018 The components in reactor are usually exposed to cyclic loading caused by frequent startups, shutdown and load fluctuations which lead to ratcheting effect.

Ratcheting-Fatigue Behavior of Harmonic-Structure-Designed SUS316L Stainless Steel
Metals, 2021 Stainless steels with harmonic-structure design have a great balance of high strength and high ductility. Therefore, it is imperative to investigate their fatigue properties for engineering applications.

CRYOGENIC RATCHETING OF PRESTRAINED AUSTENITIC STAINLESS STEEL S30408
Jixie qiangdu, 2020 Taking advantage of the EUM-25 K20 tension-torsion fatigue testing machine by CARE,the cryogenic uniaxial ratcheting tests were carried out for the S30408 specimens with and without weld,and with 0%,8%,and 12% pre-strains at110 K.

Biomechanical investigation of a novel ratcheting arthrodesis nail [PDF]
Journal of Orthopaedic Surgery and Research, 2010 Background Knee or tibiotalocalcaneal arthrodesis is a salvage procedure, often with unacceptable rates of nonunion. Basic science of fracture healing suggests that compression across a fusion site may decrease nonunion.

EPL (Europhysics Letters), 2009 We present a generic formalism to describe Brownian motion of particles with intrinsic asymmetry and give predictions for the drift behavior in unbiased time-dependent force fields. Our findings are supported by molecular dynamics simulations.

Ratcheting up the ratchet: on the evolution of cumulative culture [PDF]
Philosophical Transactions of the Royal Society B: Biological Sciences, 2009 Some researchers have claimed that chimpanzee and human culture rest on homologous cognitive and learning mechanisms. While clearly there are some homologous mechanisms, we argue here that there are some different mechanisms at work as well. Chimpanzee cultural traditions represent behavioural biases of different populations, all within the species ...

Optimal Ratcheting of Dividends in a Brownian Risk Model [PDF]
, 2020 We study the problem of optimal dividend payout from a surplus process governed by Brownian motion with drift under the additional constraint of ratcheting, i.e. the dividend rate can never decrease.

Cancer Cell, 2008 In this issue of Cancer Cell, Murphy et al. describe a mouse model designed to examine the biological effects of different levels of deregulated c-myc expression. They provide evidence that distinct threshold levels of Myc are required for increased proliferation and for apoptosis in different tissues.
