TL;DR: In this article, the authors identify factors associated with frequent exacerbations in a large well-characterized severe asthma population and determine whether factors differed in patients treated with and without maintenance oral corticosteroids (OCS).

TL;DR: In this paper, an optical fibre laser velocimeter of the Doppler difference type incorporating a fibre optic directional coupler for beam amplitude division has been constructed and satisfactorily demonstrated.

TL;DR: In this article, an all-fibre, passive scheme for making extended range interferometric measurements based on the dual wavelength technique is described, where the coherence tuned interferometer network is illuminated with a single superfluorescent fibre source at 1.55 μm and the two wavelengths are synthesised at the output by means of chirped fibre Bragg gratings.

TL;DR: In this paper, the use of a monomode optical fiber sensing element in the measurement of flow velocities by an interferometric technique is described, in which the operating principle is the flow induced oscillation of the fibre caused by vortex shedding.

TL;DR: Optical current sensors which exploit the Faraday effect have been intensively researched and developed for use in the power distribution industry for more than a decade [1, 2, the authors,.
