Spectral element method simulation of three-dimensional sedimentary basin under reverse-fault earthquakes

地震科学进展, 2020
Near-fault ground motion can cause serious earthquake disaster in the near-field area，especially when there is sedimentary topography in the area. At present，there are no reports on the ground motion response of sedimentary basins under the action of ...

Evaluation of underground blast-induced ground motions through near-surface low-velocity geological layers

Journal of Rock Mechanics and Geotechnical Engineering, 2023
Surface ground motion produced by underground blasts is significantly influenced by near-surface geological conditions. However, near-surface low-propagation velocity layers were always ignored in past analyses of ground motions due to their thin ...

Effects of Topography on Seismic-Wave Propagation: An Example from Northern Taiwan [PDF]

, 2009
Topography influences ground motion and, in general, increases the amplitude of shaking at mountain tops and ridges, whereas valleys have reduced ground motions, as is observed from data recorded during and after real earthquakes and from numerical ...

Time after time – circadian clocks through the lens of oscillator theory

FEBS Letters, EarlyView.
Oscillator theory bridges physics and circadian biology. Damped oscillators require external drivers, while limit cycles emerge from delayed feedback and nonlinearities. Coupling enables tissue‐level coherence, and entrainment aligns internal clocks with environmental cues.

Biomechanical analysis of the penalty-corner drag-flick of elite male and female hockey players [PDF]

, 2010
The aim of this study was to analyse the kinematic sequencing in the penalty-corner drag-flicks of elite male and female field hockey players of international calibre. Thirteen participants (one skilled male drag-flicker and six male and six female elite

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
