Dynamical response of a rocking rigid block [PDF]
Chaos: An Interdisciplinary Journal of Nonlinear Science, 2021 This paper investigates the complex dynamical behavior of a rigid block structure under harmonic ground excitation, thereby mimicking, for instance, the oscillation of the system under seismic excitation or containers placed on a ship under periodic acting of sea waves. The equations of motion are derived, assuming a large frictional coefficient at the

Shaking table tests on seismic response of rocking frame structure considering foundation uplift
Yantu gongcheng xuebao, 2021 The separation of structural foundation and foundation soil, namely the foundation uplift, is inevitable in strong earthquakes, so the concept of rocking isolation is gradually proposed.

Fluctuation-response relation in a rocking ratchet [PDF]
Physical Review E, 2004 The relationship between the positional fluctuation and mechanical response for a thermal ratchet at a nonequilibrium steady state was investigated experimentally and considered theoretically. We constructed a ratchet system using a scanning optical trapping system and microbeads (0.20 microm diameter), which is interpreted as a realization of a ...

The exercise pressor response to indoor rock climbing [PDF]
Journal of Applied Physiology, 2020 This case study provides original data on the exercise pressor response to indoor rock climbing and associated training exercises through the use of an indwelling femoral arterial catheter. Our subjects exhibited systolic/diastolic blood pressures that exceeded values often reported during upper-limb resistance exercise.
