Solitons in one-dimensional nonlinear Schrodinger lattices with a local inhomogeneity
Flow characteristics discrete nonlinear schrodinger equation linear point defects focusing on the lattice defects
2014/12/25
In this paper we analyze the existence, stability, dynamical formation, and mobility properties of localized solutions in a one-dimensional system described by the discrete nonlinear Schrödinger ...
Collisional-inhomogeneity-induced generation of matter-wave dark solitons
Dark soliton condensate numerical simulation of the space is not uniform shear wave scattering length one-dimensional BEC 2 d
2014/12/24
We propose an experimentally relevant protocol for the controlled generation of matter-wave dark solitons in atomic Bose–Einstein condensates (BECs). In particular, using direct numerical simulations,...
Effects of boundaries and density inhomogeneity on states of vortex matter in Bose-Einstein condensates at finite temperature
Quantum vortices 3 d eddy current condensate vortex entanglement
2014/12/19
Most of the literature on quantum vortices predicting various states of vortex matter in three dimensions at finite temperatures in quantum fluids is based on the assumption of an extended and homogen...
Particle drift in turbulent flows: the influence of local structure and inhomogeneity
turbulent structures particle dispersion drift PDF approach
2012/5/31
The way particles interact with turbulent structures, particularly in regions of high vorticity and strain rate, has been investigated in simulations of homogeneous turbulence and in simple flows whic...
Inhomogeneity of the phase space of the damped harmonic oscillator under Levy noise
Inhomogeneity of the phase space damped harmonic oscillator Levy noise Statistical Mechanics
2012/4/19
The damped harmonic oscillator under symmetric L\'{e}vy white noise shows inhomogeneous phase space, which is in contrast to the homogeneous one of the same oscillator under the Gaussian white noise, ...
Influence of Filter Inhomogeneity on Air Filtration of Nanoparticles
Collection efficiency Diffusional regime Fiber packing inhomogeneity Pressure drop
2016/3/28
Thermal rebound of nanoparticles on the surface of fibers is of big concern in collecting nanoparticles. Another factor
influencing the collection of nanoparticles is the inhomogeneity of fiber packi...
Adaptation to anisotropy and inhomogeneity via dyadic piecewise polynomial selection
Adaptation to anisotropy inhomogeneity via dyadic piecewise polynomial selection
2011/3/23
This article is devoted to nonlinear approximation and estimation via piecewise polynomials built on partitions into dyadic rectangles. The approximation rate is studied over possibly inhomogeneous an...

2011/3/22
This article is devoted to nonlinear approximation and estimation via piecewise polynomials built on partitions into dyadic rectangles. The approximation rate is studied over possibly inhomogeneous an...
Lorentz invariance, nonzero minimal uncertainty in position, and inhomogeneity of space at the Planck scale
Lorentz invariance nonzero minimal uncertainty
2010/12/24
The suspicion that the existence of a minimal uncertainty in position measurements violates Lorentz invariance seems unfounded. It is shown that the existence of such a nonzero minimal uncertainty in...
Effect of Inhomogeneity of Light from Light Curing Units on the Surface Hardness of Composite Resin
Light curing unit Light intensity Knoop hardness number
2009/9/11
This study investigated the characteristics of output light from different types of light curing units, and their effects on polymerization of light-activated composite resin. Three quartz-tungsten-ha...
Intensity inhomogeneity (IIH) is often encountered in MR imaging, and a number of techniques have been devised to correct this artifact. This paper attempts to review some of the recent developments i...
Joint Brain Parametric T1-Map Segmentation and RF Inhomogeneity Calibration
Brain Parametric T1-Map Segmentation RF Inhomogeneity Calibration
2009/9/4
We propose a constrained version of Mumford and Shah's (1989) segmentation model with an information-theoretic point of view in order to devise a systematic procedure to segment brain magnetic resonan...
Influence of Tissue Inhomogeneity on Eddy Current Distribution in Magnetic Stimulation Therapy for Urinary Incontinence—Using Threedimensional Experimental and Computer Models—
magnetic stimulation current distribution inhomogeneity abdomen model
2009/6/9
The effect of magnetic stimulation for the treatment of urinary incontinence has been explained as a re-activation of lost functions of the pelvic floor muscles. A model study was used to investigate ...
Comparison of high-latitude line-of-sight ozone column density with derived ozone fields and the effects of horizontal inhomogeneity

2009/1/8
Extensive ozone measurements were made during the second SAGE III Ozone Loss and Validation Experiment (SOLVE II). We compare high-latitude line-of-sight (LOS) slant column ozone measurements from the...
Physical controls on orographic cirrus inhomogeneity
Physical control orographic cirrus inhomogeneity
2008/12/15
Optical depth distributions (P(σ)) are a useful measure of radiatively important cirrus (Ci) inhomogeneity. Yet, the relationship between P(σ) and underlying cloud physical processes remains unclear. ...
