Broader, flatter optical spectra of passively mode-locked semiconductor lasers for a wavelength-division multiplexing source [PDF]

, 1997
Using the time domain master equation for a complex electric-field pulse envelope, we find analytical results for the optical spectra of passively mode-locked semiconductor lasers. The analysis includes the effect of optical nonlinearity of semiconductor

Regular and Singular Pulse and Front Solutions and Possible Isochronous Behavior in the Short-Pulse Equation: Phase-Plane, Multi-Infinite Series and Variational Approaches [PDF]

, 2014
In this paper we employ three recent analytical approaches to investigate the possible classes of traveling wave solutions of some members of a family of so-called short-pulse equations (SPE).

Wave Propagation in a Strongly Nonlinear Locally Resonant Granular Crystal

, 2017
In this work, we study the wave propagation in a recently proposed acoustic structure, the locally resonant granular crystal. This structure is composed of a one-dimensional granular crystal of hollow spherical particles in contact, containing linear ...

Pulse wave analysis and diabetes mellitus. A systematic review

Biomedical Papers, 2017
Cardiovascular (CV) disease is the primary cause of death in diabetic patients and one of the explanations may be increased arterial stiffness. Arterial stiffness assessment using pulse wave analysis, is a predictive factor of CV events.

Evidence of racial differences in peripheral blood pressure, central haemodynamics and arterial stiffness between young Black and White women

Experimental Physiology
Hypertension diagnosed via peripheral (brachial) blood pressure (pBP) is a strong independent predictor of overt cardiovascular disease (CVD). However, central (aortic) blood pressure (cBP), which is influenced by arterial stiffness, may be more strongly
