Low frequency vibrations disrupt left-right patterning in the Xenopus embryo. [PDF]

open access: yesPLoS ONE, 2011
The development of consistent left-right (LR) asymmetry across phyla is a fascinating question in biology. While many pharmacological and molecular approaches have been used to explore molecular mechanisms, it has proven difficult to exert precise ...

Human tremor model considering randomness of refractory period

open access: yesNihon Kikai Gakkai ronbunshu, 2017
Even in a state that the person is resting, the person vibrates with a small amplitude. This vibration is called human tremor. For example, when performing precise work such as watch assembly or surgical operation, the tremor will have an influence on ...

ON ACTIVE SYNCHROPHASING CONTROL OF VIBRATION FOR A FLOATING RAFT VIBRATION ISOLATION SYSTEM

open access: yes, 2015
A floating raft vibration isolation system installed on a flexible hull-like structure is described in this paper. Four vibration exciters, in which two counter rotating shafts with the same balanced masses are driven by a phase asynchronous motor, are ...
