Coal Mining as a Driver of Land Use and Land Cover Change and Degradation: A Case in Moatize City, Mozambique

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Coal remains a major global energy source despite ongoing environmental controversies, particularly, regarding climate change and landscape transformation. This study investigates the spatiotemporal dynamics of land use and land cover (LULC) in the Moatize Coal Basin (MCB), Mozambique, between 1990 and 2024, with a specific focus on land ...

Sensitivity‐Tunable Complex Permittivity Sensing Enabled by Bound States in the Continuum in a Waveguide‐Resonator System

open access: yesLaser &Photonics Reviews, EarlyView.
This work introduces two types of bound states in the continuum (BICs) and their merging in a waveguide‐resonator system, which significantly enhances the quality factor (Q$Q$). Benefiting from the high‐Q$Q$ characteristics of quasi‐BICs, a sensitivity‐tunable complex permittivity sensor is developed based on this system, achieving improvements of 93 ...

Mapping rail wear transitions [PDF]

open access: yes, 2003
This paper outlines work carried out to produce maps of\ud rail material wear coefficients taken from laboratory\ud tests run on twin disc and pin-on-disc machines as well\ud as those derived from measurements taken in the field.\ud Wear transitions are identified using the maps and\ud defined in terms of slip and contact pressure.

Loop Quantum Photonic Chip for Coherent Multi‐Time‐Step Evolution

open access: yesLaser &Photonics Reviews, EarlyView.
A loop quantum photonic chip (Loop‐QPC) enabling efficient multi‐step quantum simulation in a single run is demonstrated. Combining recirculating loops with cycle‐or‐measure control, Loop‐QPC eliminates repeated reprogramming and reduces loss. Experimental demonstration of three‐step unitary evolution confirms high‐fidelity operation, showcasing the ...
