Regularities in discrete hierarchy seismo-acoustic mode in a geophysical field
geophysical field seismo-acoustic regime auto similarity fractal structure
2015/8/28
Some regularities in seismo acoustic mode have been studied during the preparation and development of dynamic events generated during the deformation at different scales in a geophysical field. The ti...
Mirror mode structures and ELF plasma waves in the Giacobini-Zinner magnetosheath
Mirror mode structures ELF plasma waves Giacobini-Zinner magnetosheath
2009/11/13
We show evidence for mirror mode structures at comet Giacobini-Zinner. These are plasma structures with alternating high ß and low ß regions driven unstable when ß /ß
We investigate trapping of mirror modes in a magnetic slab. This model is a simplification of a real situation in front of the magnetopause where mirror waves may become trapped in a region close to t...
Generation of second mode solitary waves by the interaction of a first mode soliton with a sill
second mode solitary waves first mode soliton sill
2009/11/12
Results of an experimental and theoretical study of the interaction of a first mode internal solitary wave with a localised bottom topography (sill) are presented. Laboratory experiments have been per...
A universal mirror wave-mode threshold condition for non-thermal space plasma environments
universal mirror wave-mode threshold condition non-thermal space plasma environments
2009/11/12
Magnetic fluctuations are recognized in a large variety of space plasmas by increasingly high resolution, in situ observations as mirror wave mode structures. A typical requirement for the excitation ...
The strange physics of low frequency mirror mode turbulence in the high temperature plasma of the magnetosheath
strange physics low frequency mirror mode turbulence high temperature plasma
2009/11/11
Mirror mode turbulence is the lowest frequency perpendicular magnetic excitation in magnetized plasma proposed already about half a century ago by Rudakov and Sagdeev (1958) and Chandrasekhar et al. (...
One-dimensional hybrid code simulations are presented, carried out in order both to study solitary waves of the slow mode branch in an isotropic, collisionless, medium-β plasma (βi=0.25) and to test t...

Seismo-ionospheric coupling correlation analysis earthquakes empirical mode decomposition
2009/10/30
Ionospheric variability as a result of earthquake events is a confirmed phenomenon as published in various seismo-ionospheric coupling studies. Generally, ionospheric variations resulting from earthqu...

Effectiveness of multi-mode surface wave inversion in shallow engineering site investigations
surface wave higher mode sensitivity phase velocity inversion multi-mode Vs structure
2009/3/5
Inversion of multi-mode surface-wave phase velocity for shallow engineering site investigation has received much attention in recent years. A sensitivity analysis and inversion of both synthetic and f...
Transition of mode II cracks from sub-Rayleigh to intersonic speeds in the presence of favorable heterogeneity
Dynamic fracture Supershear transition of earthquakes Crack mechanics Elastic material Boundary integral equations
2014/4/8
Understanding sub-Rayleigh-to-intersonic transition of mode II cracks is a fundamental problem in fracture mechanics with important practical implications for earthquake dynamics and seismic radiation...
