Stability of the Einstein static universe in modified theories of gravity
Einstein static universe modified theories of gravity
font style='font-size:12px;'>
2010/3/17
We present a brief overview of the stability analysis of the Einstein static universe in various modified theories of gravity, like f(R) gravity, Gauss-Bonnet or f(G) gravity, and Horava-Lifshitz grav...
Towards a more exact value of deflection of light due to static gravitational mass
static gravitational mass deflection of light
font style='font-size:12px;'>
2010/3/17
The deflection of a ray of light passing close to a gravitational mass, is generally calculated from the null geodesic which the light ray (photon) follows. However, there is an alternate approach, wh...
Gravitational instability of the inner static region of a Reissner-Nordstrom black hole
Gravitational instability black hole inner static region
font style='font-size:12px;'>
2010/3/17
Reissner--Nordstr\"om black holes have two static regions: $r > \ro$ and $0 < r < \ri$, where $0 < \ri < \ro$ are the inner and outer horizon radii. The stability of the exterior static region has bee...

The quasi-static approximation of the spring-slider motion
quasi-static approximation spring-slider motion
font style='font-size:12px;'>
2009/11/16
The spring-slider is a simple dynamical system consisting in a massive block sliding with friction and pulled through a spring at a given velocity. Understanding the block motion is fundamental for st...
Faults self-organized by repeated earthquakes in a quasi-static antiplane crack model
Faults self-organized by repeated earthquakes quasi-static antiplane crack model
font style='font-size:12px;'>
2009/11/13
We study a 2D quasi-static discrete crack anti-plane model of a tectonic plate with long range elastic forces and quenched disorder. The plate is driven at its border and the load is transferred to al...

Width dependent collisionless electron dynamics static fields shock ramp Phase space portrait
font style='font-size:12px;'>
2009/11/13
We study numerically in detail the behaviour of electrons in the strongly inhomogeneous static magnetic and electric fields, which are typical for thin quasiperpendicular collisionless shocks. We pay ...

Width dependent collisionless electron dynamics static fields shock ramp
font style='font-size:12px;'>
2009/11/13
We study the collisionless dynamics of electrons in the shock ramp using the numerical trajectory analysis in the model electric and magnetic fields of the shock. Even with very modest assumptions abo...

A mechanical model of the quasi-static interface of a mode I crack between a rigid and a pressure-sensitive viscoelastic material was established to investigate the mechanical characteristic of ship-b...
Non-static Quantum Bit Commitment
Non-static Quantum Commitment
font style='font-size:12px;'>
2010/4/8
Quantum bit commitment has been known to be impossible by the independent proofs of Mayers, and Lo and Chau, under the assumption that the whole quantum states right before the unveiling phase are sta...
Stochastic emergence of multiple intermediates detected by single-molecule quasi-static mechanical unfolding of protein

font style='font-size:12px;'>
2010/12/2
Experimental probing of a protein-folding energy landscape can be challenging, and energy landscapes comprising multiple intermediates have not yet been defined. Here, we quasi-statically unfolded sin...
