Dispersion-managed solitons at normal average dispersion [PDF]

open access: possibleNonlinear Optics '98. Materials, Fundamentals and Applications Topical Meeting (Cat. No.98CH36244), 1998
We find that in a dispersion-managed fiber, in which the strength of the dispersion management is above some threshold, solitons can exist with normal average dispersion. When the normal average dispersion is below some limiting value there exist two soliton solutions with the same pulse duration and different pulse energies.

On the Dispersion of Resistivity and Dielectric Constant of Some Semiconductors at Audiofrequencies

, 1951
Semiconducting ${\mathrm{Ni}}_{0.4}$${\mathrm{Zn}}_{0.6}$${\mathrm{Fe}}_{2}$${\mathrm{O}}_{4}$, prepared in different ways, has been investigated. It appeared that the ac resistivity and the apparent dielectric constant of the material show a dispersion ...

Molecular‐Level Dispersion of Graphene into Poly(vinyl alcohol) and Effective Reinforcement of their Nanocomposites

, 2009
Despite great recent progress with carbon nanotubes and other nanoscale fillers, the development of strong, durable, and cost‐efficient multifunctional nanocomposite materials has yet to be achieved.

Solid dispersion of poorly water-soluble drugs: early promises, subsequent problems, and recent breakthroughs.

Journal of Pharmacy and Science, 1999
Although there was a great interest in solid dispersion systems during the past four decades to increase dissolution rate and bioavailability of poorly water-soluble drugs, their commercial use has been very limited, primarily because of manufacturing ...

Anomalous transit-time dispersion in amorphous solids

, 1975
Measurements of the transient photocurrent I(t) in an increasing number of inorganic and organic amorphous materials display anomalous transport properties, The long tail of I(t) indicates a dispersion of carrier transit times.

The Dispersion of Physicians

JAMA: The Journal of the American Medical Association, 1982
In this issue ofThe Journal(p 2392), Newhouse and colleagues demonstrate the rapid geographic diffusion of physicians in most specialties during the period from 1970 to 1979. This demonstration will probably come as no surprise, since it confirms the personal observation of many physicians, who have watched the influx of more and more young colleagues

The Dispersion of Surface Waves on Multilayered Media

, 1953
A matrix formalism developed by W. T. Thomson is used to obtain the phase velocity dispersion equations for elastic surface waves of Rayleigh and Love type on multilayered solid media.

Fundamentals of the hydrodynamic mechanism of splitting in dispersion processes

, 1955
The splitting of globules is an important phenomenon during the final stages of disintegration processes. Three basic types of deformation of globules and six types of flow patterns causing them are distinguished.
