Postseismic deformation and body forces shaping the Apennines and adjacent sedimentary basins in Umbria-Marche
Viscoelastic relaxation Aseismic slip Body forces Normal faults
2015/9/1
The geodynamic complexity of the Apennines and adjacent sedimentary basins in Umbria-Marche (North-Central Italy) makes the dynamics of the present day deformation and its relationships with the seism...
Fast computation of optimal contact forces
Calculation of point-contact friction model power optimization problem semidefinite programming
2015/8/10
We consider the problem of computing the smallest contact forces, with point-contact friction model, that can hold an object in equilibrium against a known external applied force and torque. It is kno...
A fast solver for the Stokes equations with distributed forces in complex geometries
Stokes equations Fast solvers Integral equations Double-layer potential Fast multipole methods Embedded domain methods Immersed interface methods Fictitious domain methods Cartesian grid methods Moving boundaries
2015/7/14
We present a new method for the solution of the Stokes equations. The main features of our method are: (1) it can be applied to arbitrary geometries in a black-box fashion; (2) it is second-order accu...
Analysis of land cover change and its driving forces in a desert oasis landscape of Xinjiang, northwest China
Drought warming land cover extreme drought desert oasis the landsat images traditional vegetation
2015/1/6
The combined effects of drought, warming and the changes in land cover have caused severe land degradation for several decades in the extremely arid desert oases of southern Xinjiang, northwest China....
Non-pairwise intervortex interaction forces
Superconducting vortex and vortex compact vortex two-component type superconductor
2014/12/18
We demonstrate the existence of a new kind of non-pairwise multivortex interaction forces, which are present between superconducting vortices along with pairwise vortex interactions. We show that the ...
Singular parabolic p-Laplacian systems under non-smooth external forces. Regularity up to the boundary
Initial-boundary value problems p-Laplacian parabolic singular systems regularity up to the boundary
2012/6/30
We study the regularity of the solutions to initial-boundary value problems for N-systems of the p-Laplacian type, in $n\geq 3$ space variables, with square-integrable external forces in the space-tim...
Relativistic forces in Lagangian mechanics
Relativistic forces Lagangian mechanics Mathematical Physics
2012/6/27
We give a general definition of \emph{relativistic force} in the context of Lagrangian mechanics. Once this is done we prove that the only relativistic forces which are linear on the velocities are th...
Study on Correlation of Tidal Forces with Global Great Earthquakes
Tidal Force Earthquake Run Test Seismic Belt
2013/3/7
The correlation between the celestial tidal forces and earthquakes has been a controversial problem, although its research history is very long. This paper analyzes the relation between the tidal forc...
Modelling pulsar glitches with realistic pinning forces: a hydrodynamical approach
Modelling pulsar glitches realistic pinning forces hydrodynamical approach
2011/10/17
Although pulsars are one of the most stable clocks in the universe, many of them are observed to 'glitch', i.e. to suddenly increase their spin frequency (\nu) with fractional increases that range fro...
Three-nucleon forces (3NF) are investigated from two-flavor lattice QCD simulations. We utilize the Nambu-Bethe-Salpeter (NBS) wave function to determine two-nucleon forces (2NF) and 3NF in the same f...

Coulomb Forces Scattering Amplitude on Its Residue
2011/7/20
Explicit expressions of the vertex constant for the decay of a nucleus into two charged particles for an arbitrary orbital momentum $l$ are derived for the standard expansion of the effective-range fu...

2011/9/15
Abstract: We prove propagation of chaos for a system of particles interacting with a singular interaction force of the type $1/|x|^\alpha$, with $\alpha <1$ in dimension $d \geq 3$. We also recover th...
