Hate networks revisited: time and user interface dependence study of user emotions in political forum
Hate networks time user interface user emotions political forum
2011/8/4
Abstract: The paper presents analysis of time evolution within am Internet political forum, characterized by large political differences and high levels of emotions. The study compares samples of disc...
Huge broadening of the crystal-fluid interface for sedimenting colloids
the crystal-fluid interface sedimenting colloids Huge broadening
2011/8/17
Abstract: For sedimenting colloidal hard spheres, the propagation and broadening of the crystal-fluid interface is studied by Brownian dynamics computer simulations of an initially homogeneous sample....
The NStED Periodogram Service and Interface for Public CoRoT Data
Periodogram Service Interface Public CoRoT
2011/9/30
As part of the NASA-CNES agreement, the NASA Star and Exoplanet Database (NStED) serves as the official US portal for the public CoRoT data products. NStED is a general purpose archive with the aim of...
On modeling and simulation of surfactants in diffuse interface flow
modeling and simulation surfactants interface flow
2011/9/29
An existing phase- eld model of two immiscible uids with a single soluble surfactant present is discussed in detail. We analyze the well-posedness of the model and show that it is mathematically ill-p...
A New Type of Traveling Interface Modulations in a Catalytic Surface Reaction
Traveling Interface Modulations spatially separated domains
2011/7/6
A new type of traveling interface modulations has been observed in the NH$_3$ + O$_2$ reaction on a Rh(110) surface. A model is set up which reproduces the effect, which is attributed to diffusional m...
Spiky development at the interface in Rayleigh-Taylor instability: Layzer approximation with second harmonic
Layzer second harmonic
2011/8/30
Layzer’s approximation method for investigation of two fluid interface structures associated with Rayleigh Taylor instability for arbitrary Atwood number is extended with the inclusion of second harmo...
On the moments and the interface of the symbiotic branching model
Symbiotic branching model mutually catalytic branching
2011/1/19
In this paper we introduce a critical curve separating the asymptotic behavior of the moments of the symbiotic branching model,introduced by Etheridge and Fleischmann [Stochastic Process. Appl.114 (20...
Energy stable and momentum conserving interface stabilised finite element method for the incompressible Navier-Stokes equations
Finite element method stabilised finite element methods
2011/3/3
An interface stabilised finite element method for the incompressible Navier-Stokes
equations is presented. The method inherits the attractive stabilising mechanism of upwinded discon-tinuous Galerkin...
Carleman estimates for elliptic operators with jumps at an interface: Anisotropic case and sharp geometric conditions
Carleman estimate elliptic operator non-smooth coecient quasimode
2011/2/21
We consider a second-order selfadjoint elliptic operator with an anisotropic di usion matrix having a jump across a smooth hypersurface. We prove the existence of a weight-function such that a Carlema...

Discrete breathers at the interface diatomic monoatomic granular chain
2010/12/28
In the present work, we develop a systematic examination of the existence, stability and dynamical properties of a discrete breather at the interface between a diatomic and a monoatomic granular chain...
New structural model for GeO2/Ge interface: A first-principles study
New structural model for GeO2/Ge interface first-principles study
2010/11/24
First-principles modeling of a GeO2/Ge(001) interface reveals that sixfold GeO2, which is derived from cristobalite and is different from rutile, dramatically reduces the lattice mismatch at the inter...
Bosonic enhancement of spontaneous emission near an interface
Bosonic enhancement spontaneous emission
2010/11/24
We show how the spontaneous emission rate of an excited two-level atom placed in a trapped Bose-Einstein condensate of ground-state atoms is enhanced by bosonic stimulation. This stimulation depends o...
