Research on correlation between regional seismic characteristics and coal mine rockburst in Hegang

Gong-kuang zidonghua
Natural earthquakes and coal mine rockbursts are both transient fracturing processes of stress release in crustal rock mass. Current research primarily investigates the correlation between earthquakes and rockbursts from either the geodynamic environment

The effect of propagation in air on the filament spectrum [PDF]

, 2012
Filamentation studies traditionally start from letting a beam focus in air. We present filament studies with control over the preparation propagation, in air or vacuum, using an aerodynamic window. The spectral content of the filament strongly depends on

Constraint on the focal mechanism of the 2011 Tohoku earthquake from the radial modes

Geodesy and Geodynamics
Different from other normal modes of the Earth's free oscillation that depend on all the six components (Mrr, Mtt, Mpp, Mrt, Mrp, and Mtp) of the centroid moment tensor, the amplitudes of the radial modes depend on the Mrr component (e.g., scalar moment (

Microbunching And Coherent Acceleration Of Electrons By Subcycle Laser Pulses [PDF]

, 1997
The pick up and acceleration of all plasma electrons irradiated by an intense, subcyclic laser pulse is demonstrated via analytical and numerical calculations.

Entanglement, intractability and no-signaling

, 2010
We consider the problem of deriving the no-signaling condition from the assumption that, as seen from a complexity theoretic perspective, the universe is not an exponential place.

Exact off-resonance near fields of small-size extended hemielliptic 2-D lenses illuminated by plane waves [PDF]

, 2009
The near fields of small-size extended hemielliptic lenses made of rexolite and isotropic quartz and illuminated by E- and H-polarized plane waves are studied.

Coupling biochemistry and mechanics in cell adhesion: a model for inhomogeneous stress fiber contraction

, 2007
Biochemistry and mechanics are closely coupled in cell adhesion. At sites of cell-matrix adhesion, mechanical force triggers signaling through the Rho-pathway, which leads to structural reinforcement and increased contractility in the actin cytoskeleton.

Mechanisms of growth inhibition of primary prostate epithelial cells following gamma irradiation or photodynamic therapy including senscence, necrosis, and autophagy, but not apoptosis [PDF]

, 2015
In comparison to more differentiated cells, prostate cancer stem-like cells are radioresistant, which could explain radio-recurrent prostate cancer. Improvement of radiotherapeutic efficacy may therefore require combination therapy.

Effects of pyruvate administration on infarct volume and neurological deficits following permanent focal cerebral ischemia in rats [PDF]

, 2003
Recent experimental evidences indicate that pyruvate, the final metabolite of glycolysis, has a remarkable protective effect against different types of brain injury.

Characteristics of focal mechanisms in Chile subduction

Geodesy and Geodynamics, 2012
We use the Centroid Moment Tensor (CMT) solution of the earthquakes occurred in Chile subduction to analyze the characteristics of focal mechanisms. We define the angle between P, B, and T axes of focal mechanisms and three stress axes of tectonic stress
