A long period grating based directional flow sensor [PDF]
, 2008 A chirped long period grating (LPG) is used as a directional flow sensor by monitoring the change in the transmission spectrum upon immersion in an oil of refractive index higher than that of the fibre cladding. The change in profile of an attenuation

Incubation Period: Not well determined; may be as short as 1-3 days.
, 2014 Presumably until discharges of the mouth and nose no longer contain virulent pneumococci in significant numbers. Penicillin will render patients with susceptible strains noninfectious within 24-48 hours.

Another 'futile quest'? A simulation study of Yang and Land's Hierarchical Age-Period-Cohort model [PDF]
, 2013 Background: Whilst some argue that a solution to the age-period-cohort (APC) 'identification problem' is impossible, numerous methodological solutions have been proposed, including Yang and Land's Hierarchical-APC (HAPC) model: a multilevel model ...

Multiplexing of fiber-optic long-period grating-based interferometric sensors [PDF]
, 2007 Two long-period gratings (LPGs) fabricated in series in an optical fiber form a Mach-Zehnder interferometer, producing a sinusoidal channelled spectrum within the characteristic LPG attenuation bands, which has the appearance of an interference fringe ...

Modification of the refractive index response of long period gratings using thin film overlays. [PDF]
, 2005 The response of a fibre optic long period grating (LPG) to the surrounding refractive index is shown to be modified by the deposition of a thin film of thickness of order 100 nm onto the cladding.

Exploiting the critical perioperative period to improve long-term cancer outcomes
Nature Reviews Clinical Oncology, 2015 Evidence suggests that the perioperative period and the excision of the primary tumour can promote the development of metastases—the main cause of cancer-related mortality.

Optical fibre long period grating based selective vapour sensing of volatile organic compounds [PDF]
, 2010 The chemical sensing capabilities of an optical fibre long period grating (LPG) coated with a functional material are explored. The LPG period and coating thickness are chosen such that the mode transition region, characteristic of LPGs coated with ...
