ALMA CO Observations of Supernova Remnant N63A in the Large Magellanic Cloud: Discovery of Dense Molecular Clouds Embedded within Shock-Ionized and Photoionized Nebulae

open access: yes, 2019
We carried out new $^{12}$CO($J$ = 1-0, 3-2) observations of a N63A supernova remnant (SNR) from the LMC using ALMA and ASTE. We find three giant molecular clouds toward the northeast, east, and near the center of the SNR.

Comparative Analysis of High‐Throughput Phenotyping Techniques for Early Detection of Herbicide Stress

open access: yesWeed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT Early detection of herbicide‐induced stress is essential for optimising weed control, improving crop safety and advancing precision agriculture practices. While non‐destructive imaging technologies offer great potential for rapid stress diagnosis, direct comparisons of their performance across species, herbicides and application rates remain ...

Gravitational power from cosmic string loops with many kinks

open access: yes, 2011
We investigate the effect of a large number of kinks on the gravitational power radiated by cosmic string loops. We show that the total power radiated by a loop with N left-moving and right-moving kinks is proportional to N and increases with the typical

Quantifying Additive Manufacturing Vapor Plumes Using Laser‐Induced Breakdown Spectroscopy, Synchrotron X‐Ray Radiography and Simulations

open access: yesAdvanced Science, Volume 13, Issue 12, 27 February 2026.
This study presents a novel in situ laser‐induced breakdown spectroscopy system for monitoring metal vapors produced by the intense laser‐metal interactions in laser powder bed fusion additive manufacturing and laser welding. The insights from this new technique reveal changes in alloy compositions and provide the first in situ validation of multi ...

Support‐Driven Acidity and Interfacial Effects in Mo2C Catalysts for Glycerol Hydrodeoxygenation to LPG

open access: yesChemCatChem, Volume 18, Issue 3, 12 February 2026.
Mo2C nanoparticles, supported on Nb2O5, γ‐Al2O3, or TiO2, under optimized conditions and DFTB insights, are crucial for efficient Liquefied Petroleum Gas (LPG) production, representing a promising advance in glycerol conversion into renewable fuels. ABSTRACT This study explores the hydrodeoxygenation (HDO) of glycerol into liquid petroleum gas (LPG ...

Joint Decoding of LDPC Codes and Finite-State Channels via Linear-Programming

open access: yes, 2011
This paper considers the joint-decoding (JD) problem for finite-state channels (FSCs) and low-density parity-check (LDPC) codes. In the first part, the linear-programming (LP) decoder for binary linear codes is extended to JD of binary-input FSCs.

Epstein‐Barr Virus Infection at Single‐Cell Resolution

open access: yesJournal of Medical Virology, Volume 98, Issue 2, February 2026.
ABSTRACT Epstein‐Barr virus (EBV) infection has been studied at single‐cell resolution for six decades and counting. Such investigations can reveal virus‐host interactions and their dependence on viral strain, cellular niche, infection program, immune response regulation, and time.

Costas loop lock detection in the advanced receiver [PDF]

open access: yes
The advanced receiver currently being developed uses a Costas digital loop to demodulate the subcarrier. Previous analyses of lock detector algorithms for Costas loops have ignored the effects of the inherent correlation between the samples of the phase ...

How Far Are Two Symmetric Matrices From Commuting? With an Application to Object Characterisation and Identification in Metal Detection

open access: yesMathematical Methods in the Applied Sciences, Volume 49, Issue 3, Page 1914-1942, February 2026.
ABSTRACT Examining the extent to which measurements of rotation matrices are close to each other is challenging due measurement noise. To overcome this, data is typically smoothed, and the Riemannian and Euclidean metrics are applied. However, if rotation matrices are not directly measured and are instead formed by eigenvectors of measured symmetric ...
