ObjectiveSeveral epidemiological and clinical reports associate fibromyalgia (FM) with seizure disorders, and clinical studies associate FM diagnosis with psychogenic non-epileptic seizures. However, these associations rely on self-reports of being d

Objective: Chronic fatigue syndrome (CFS) and fibromyalgia (FM) are disorders of unknown etiology and unclear pathophysiology, with overlapping symptoms of – especially muscular –fatigue and pain. Studies have shown increased muscle fiber conduct

Introduction: Fibromyalgia (FM) is a disorder of widespread muscular pain. We investigated possible differences in surface electromyography (sEMG) in clinically unaffected muscle between patients with FM and controls. Methods: sEMG was performed on t

On the effective wavelength in two-wavelength interferometry

Autor: René G Klaver, Hedser van Brug

Publikováno v: Pure and Applied Optics: Journal of the European Optical Society Part A. 7:1465-1471

A discussion on the effective wavelength in two-wavelength interferometry is given. A definition, different from the commonly adopted one, is presented and its validity is discussed. By adopting this new effective wavelength the range over which leng
