Directional supercontinuum generation: the role of the soliton [PDF]
Journal of the Optical Society of America B, volume: 36, issue: 2
(Jan. 2019) pp. A131-A138, 2019 In this paper we numerically study supercontinuum generation by pumping a silicon nitride waveguide, with two zero-dispersion wavelengths, with femtosecond pulses. The waveguide dispersion is designed so that the pump pulse is in the normal-dispersion regime.

Dispersion-managed soliton in optical fibers with zero average dispersion [PDF]
Optics Letters v. 25 (#16), pp. 1144-1146 (2000)., 2000 The dispersion-managed (DM) optical system with step-wise periodical variation of dispersion is studied in the framework of path-averaged Gabitov-Turitsyn equation. The soliton solution is obtained by iterating the path-averaged equation. The dependence of soliton parameters on dispersion map strength is investigated together with the oscillating tails

Coal dust dispersion from a coal storage pile [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2020 Open coal storage piling is considered as pollution concerned activity because when the air is dry and windy, the coal dust can disperse and cover large area causing air pollution. Knowing in advance the concentration and area affected by the coal dust

A Relationship between Nuclear Black Hole Mass and Galaxy Velocity Dispersion [PDF]
, 2000 We describe a correlation between the mass Mbh of a galaxy's central black hole and the luminosity-weighted line-of-sight velocity dispersion σe within the half-light radius.

The Slope of the Black Hole Mass versus Velocity Dispersion Correlation [PDF]
, 2002 Observations of nearby galaxies reveal a strong correlation between the mass of the central dark object MBH and the velocity dispersion σ of the host galaxy, of the form log(MBH/M☉) = α + β log(σ/σ0); however, published estimates of the slope β span a ...

Moderated estimation of fold change and dispersion for RNA-seq data with DESeq2
Genome Biology, 2014 In comparative high-throughput sequencing assays, a fundamental task is the analysis of count data, such as read counts per gene in RNA-seq, for evidence of systematic changes across experimental conditions.

, 2017 We study a synchronous dispersion process in which $M$ particles are initially placed at a distinguished origin vertex of a graph $G$. At each time step, at each vertex $v$ occupied by more than one particle at the beginning of this step, each of these ...

Investigation of vegetation effects on radionuclide dispersion
Fushe yanjiu yu fushe gongyi xuebao, 2021 In this study, we analyzed a region where accidentally released radionuclides were affected by the surrounding vegetation. A radioactive leakage accident affecting shelterbelts located on both sides of a road was selected for modeling.
