Further advances in magnetic hyperthermia might be limited by biological constraints, such as using sufficiently low frequencies and low field amplitudes to inhibit harmful eddy currents inside the patient's body. These incite the need to optimize th

Background. Taking into account the probable role that race/skin color may have for determining outcomes in maternal health, the objective of this study was to assess whether maternal race/skin color is a predictor of severe maternal morbidity. Metho

Optical Solitons in Fibers for Communication Systems
Autor: S. V. Latas, Mário F. S. Ferreira, M. H. Sousa, Margarida Facão
Publikováno v: Fiber and Integrated Optics. 24:287-313
A brief history of attempts to use solitons for optical fiber communications and of the technical developments toward making soliton transmission practical is reviewed. The main problems affecting long-distance soliton transmission, as well as techni

We review the research progress concerning some fundamental issues related to polarization-mode dispersion (PMD) in high-speed fiber-optic transmission systems. We pay particular attention to issues such as the PMD-induced pulse broadening, PMD measu

Analysis of the timing jitter of dispersion-managed solitons controlled by filters
Autor: M. H. Sousa, Mário F. S. Ferreira
Publikováno v: Laser Physics Letters. 1:491-494
Using a variational approach, an exact analytical expression is derived for the variance of the timing jitter of a dispersion-managed soliton in the presence of lumped narrow-band filters. The asymptotic timing jitter shows a linear dependence with d

Total suppression of the timing jitter in dispersion-managed soliton systems
Autor: M. H. Sousa, Mário F. S. Ferreira
Publikováno v: Laser Physics Letters. 1:602-604
An exact analytical solution is derived for the variance of the timing jitter of a dispersion-managed soliton in the presence of synchronous amplitude modulators and filters. We show that, for a given position of these control elements, a total suppr
