Accurate gas leak detection using tuneable diode lidar systems
Patent published on the 2026-05-21 in US under Ref US20260140258 by QLM TECH LTD [GB] (Ai Xiao [gb], Titchener James Graham [gb], Reed Murray Keith [gb])
Abstract: When using spectroscopic diode lidar to detect a gas of interest such as methane (CH4), detecting high concentration pathlength (CPL) values of the gas of interest may not actually indicate a plume or leak. In areas such as a refinery, where ambient gas levels may be routinely high, absorption from ambient gas measured over a long pathlength may produce the same CPL value as a much closer gas leak, leading to a false positive. By collecting and using lidar distance information in tandem with the[...]
Our summary: Tuneable diode lidar systems enhance gas leak detection accuracy. High concentration pathlength values can mislead detection in high ambient gas environments. Integrating lidar distance data with CPL values improves reliability and alarm triggering for gas leaks.

Intrinsic radial superconducting diode effect
Published on 2026-03-12 by Chuan-Shuai Huang, Weinan Lin and Xiancong Lu @IOP SCIENCE
Abstract: Using Ginzburg–Landau theory, we investigate the angular dependence of the intrinsic superconducting diode effect (SDE) in systems with mixed conventional Rashba and radial Rashba (RR) spin–orbit couplings (SOC), characterized by the so-called Rashba angle . Our results show that the admixture of the tangential and radial spin-textures introduces a pronounced phase shift in the dependence of diode efficiency η on magnetic field angle —a hallmark of the radial SDE arising from RR SOC. Impo[...]
Our summary: This study investigates the intrinsic superconducting diode effect using Ginzburg–Landau theory. It reveals a pronounced phase shift in diode efficiency due to mixed Rashba spin-orbit couplings. Higher-order magnetic field corrections show a distinct non-sinusoidal angular dependence, indicating the potential for optimizing diode devices.

Abstract: Photovoltaic (PV) systems play a significant role in renewable energy production. Due to the nonlinear and multi-modal nature of PV models, using accurate model parameters is crucial. In recent years, metaheuristic algorithms have been utilized to estimate these parameter values. While established metaheuristics like Genetic Algorithms (GAs) incorporate mechanisms such as mutation and selection to maintain diversity, they may still encounter challenges related to premature convergence when navig[...]
Our summary: This study evaluates the Bipolar Improved Roosters Algorithm (BIRA) for estimating photovoltaic parameters. BIRA is compared with established algorithms like Genetic Algorithms and Particle Swarm Optimization. Results show BIRA significantly outperforms its competitors in accuracy and reliability for PV parameter estimation.
