A Geometry-Based Guidance Law to Control Impact Time and Angle under Variable Speeds

open access: yesMathematics, 2020
To provide a feasible solution for a variable speed unmanned aerial vehicle (UAV) to home on a target with impact time and angle constraints, this paper presents a novel geometry-based guidance law composed of trajectory reshaping and tracking.

Impact of Torsion Space-Time on $t\bar{t}$ observables at Hadron Colliders [PDF]

open access: yes, 2013
Starting from the effective torsion space-time model, we study its effects on the top pair production cross section at hadron colliders. We also study the effect of this model on top pair asymmetries at the Tevatron and the LHC.

Competition between random and correlated accumulation of primary damages in impact-loaded SiC ceramics

open access: yesJournal of Asian Ceramic Societies, 2016
Samples of SiC ceramics differing in porosity in the range 1–9% were damaged by a falling weight, and the fractoluminescence (FL) activity lasting up to 0.4 ms was detected with the time resolution of 10 ns. The recorded time series of the light emission

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...
