Noble gas solubility in silicate melts:a review of experimentation and theory, and implications regarding magma degassing processes
noble gases solubility degassing silicate melts
<
2015/9/10
Noble gas solubility in silicate melts and glasses has gained a crucial role in Earth Sciences investigations and
in the studies of non-crystalline materials on a micro to a macro-scale. Due to their...
Mathematical analogies in physics. Thin-layer wave theory
Thin layer Electromagnetism Viscoelasticity Reflection and transmission coefficient
<
2015/8/17
Field theory applies to elastodynamics, electromagnetism, quantum mechanics, gravitation and other similar fields of physics, where the basic equations describing the phenomenon are based on constitut...
Bayesian inversion for finite fault earthquake source models I—theory and algorithm
Bayesian inversion finite fault earthquake source model theory algorithm
<
2014/4/9
The estimation of finite fault earthquake source models is an inherently under determined problem: there is no unique solution to the inverse problem of determining the rupture history at depth as a f...
Each observable ballistic phenomenon of a spin-stabilized rifle bullet can be explained in terms of the acceleration of gravity and the total aerodynamic force acting on that bullet. In addition to th...
Geophysical turbulence data and turbulence theory
Geophysical turbulence data turbulence theory

2009/11/16
Many vital insights into the nature of turbulence in fluids have originated from experimental data obtained in geophysical flows. Geophysical data have often helped to stimulate the creation of new tu...
We study theoretically the physical origin of the proposed discrete scale invariance of earthquake processes, at the origin of the universal log-periodic corrections to scaling, recently discovered in...
Theory of localized bipolar wave-structures and nonthermal particle distributions in the auroral ionosphere

2009/11/13
Bipolar wave structures and nonthermal particle distributions measured by the FAST satellite in regions of downward current are interpreted in terms of the nonlinear evolution of a two-stream instabil...
Dissipation and wave-ion interaction in the solar wind:Links between fluid and kinetic theory
wave-ion interaction solar wind Links between fluid and kinetic theory
<
2009/11/13
In this paper we establish links between turbulence dissipation and wave-particle interactions in the solar corona and wind. Based on quasilinear theory, a set of anisotropic, multi-component fluid eq...
A theory of the Earth's magnetic field and of sunspots,based on a self-excited dynamo incorporating the Hall effect
