Resonant photoluminescence studies of carrier localisation in c-plane InGaN/GaN quantum well structures.
In this paper we report on changes in the form of the low temperature (12 K) photoluminescence spectra of an InGaN/GaN quantum well structure as a function of excitation photon energy. As the photon energy is progressively...
Low complexity DSP for high speed optical access networking
A novel low-cost and energy-efficient approach for reaching 40 Gb/s signals is proposed for cost-sensitive optical access networks. Our proposed design is constituted of an innovative low-complex high-performance digital...
The extrudate swell singularity of Phan-Thien-Tanner and Giesekus fluids

The stress singularity for Phan-Thien-Tanner (PTT) and Giesekus viscoelastic fluids is determined for extrudate swell (commonly termed die swell). In the presence of a Newtonian solvent viscosity, the solvent stress dominates...

Numerical study of the stress singularity in stick-slip flow of the Phan-Thien Tanner and Giesekus fluids

Stick-slip flow is a challenging viscoelastic benchmark problem due to the presence of a separation or transition point at the die exit where a sudden change in flow boundary conditions occurs. We present numerical...

Litter removal in a tropical rain forest reduces fine root biomass and production but litter addition has few effects.

Nov 01, 2018
Many old-growth lowland tropical rain forests are potentially nutrient limited, and it has long been thought that many such forests maintain growth by recycling nutrients from decomposing litter. We investigated this by...
Polymer Microarrays for the Discovery and Optimization of Robust Optical-Fiber-Based pH Sensors

Polymer microarrays were utilized for the high-throughput screening and discovery of optimal polymeric substrates capable of trapping functional ratiometric fluorescence-based pH sensors. This led to the identification of...

Hurricane disturbance accelerated the thermophilization of a Jamaican montane forest
Thermophilization – changes in community composition towards greater relative abundances of species associated with warmer environments – has been described for plants and animals in many locations around the world. Disturbances...

Highly feminised sex ratio estimations for the world’s third largest nesting aggregation of loggerhead sea turtles

Despite being a fundamental life-history character, there is a paucity of populationwide, data-driven studies of primary sex ratios for any marine turtle species. The Republic of Cape Verde hosts the third-largest nesting...

Systematic Review of Evidence Pertaining to Factors That Modify Risk of Early Childhood Caries.
INTRODUCTION: A systematic review of evidence on the impact of modifiable risk factors on early childhood caries (ECC) was conducted to inform recommendations in a World Health Organization manual on ECC prevention. OBJECTIVES...
A hydrogel-based optical fibre fluorescent pH sensor for observing lung tumor tissue acidity

Technologies for measuring physiological parameters in vivo offer the possibility of the detection of disease and its progression due to the resulting changes in tissue pH, or temperature, etc. Here, a compact hydrogel-based...
