DOI: 10.1016/j.ijnonlinmec.2020.103632
Abstract: Abstract Aiming to isolate disturbance vibration for heavy payloads with low frequency, a novel hydro-pneumatic near-zero frequency vibration isolator is proposed, which possesses high-static and low-dynamic (HSLD) stiffness. And different from most isolators existing previously,… read more here.

DOI: 10.1088/1367-2630/abef28
Abstract: Metamaterials have demonstrated great potential for controlling wave propagation since they are flexibly adjustable. A new one-dimensional metamaterial model with both a negative effective moment of inertia and negative effective stiffness is proposed. A negative… read more here.

DOI: 10.1103/physrevd.100.045020
Abstract: The interplay between acceleration and radiation harbors remarkable and surprising consequences. One of the most striking is that the Larmor radiation emitted by a charge can be seen as a consequence of the Unruh thermal… read more here.

DOI: 10.1109/lsp.2019.2929442
Abstract: Epochs are the abrupt-closure events in vocal fold vibration during the production of voiced speech. Zero frequency filtering is a simple and effective technique used to estimate the glottal closure instants accurately from the speech… read more here.
