Highly Sensitive FBG Strain Sensor With Enhanced Measurement Range Based On Higher Order FWM
IEEE Photonics Journal, 2020 To meet the simultaneous requirement of high sensitivity and high measurement range is an uphill task in the development of fiber Bragg grating (FBG) strain sensor. A unique scheme of highly sensitive FBG strain sensor is proposed based on nonlinear four

Functional tooth unit, periodontal status, and association with weight change in older adults
Journal of Periodontology, Volume 97, Issue 8, Page 1807-1818, August 2026.Abstract Background Literature reports that having fewer teeth is associated with reduced chewing capacity, which in turn may lead to weight changes due to diminished oral functionality. This study aims to assess the association between functional tooth units (FTU) and periodontal status and weight change among older adults participating in the Health,

Birefringence effects in fibre-based polarisation-insensitive FWM systems
, 2022 We present a quantitative study of the effects of birefringence in polarisation-insensitive orthogonal-pump four-wave mixing (FWM) systems, that ultimately advises on appropriate fibre length selection for minimised polarisation dependent ...
