The sensitivity of the Durham mk6 ground-based atmospheric cherenkov telescope to very high energy gamma-ray sources [PDF]

open access: yes, 2001
The subject of this thesis is a determination of the sensitivity of the Durham Mk6 ground based Imaging Atmospheric Cherenkov Telescope (lACT), an instrument which uses the imaging atmospheric Cherenkov technique to detect Very High Energy (VHE) gamma ...

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

High Lithium Concentrations in Covalently Bonded Germanium Nanoparticle Assembled Layers

open access: yesAdvanced Energy and Sustainability Research, Volume 7, Issue 7, July 2026.
Germanium nanoparticles have a promising volumetric lithium storage capacity and are here synthesized by magnetron sputtering and lithiated to high concentrations to study the robustness against cracking. A detailed structural investigation following electrochemical lithium intercalation, using Raman spectroscopy, AFM, and XAFS provided detailed ...

Deep-Learning-Based Cosmic-Ray Mass Reconstruction Using the Water-Cherenkov and Scintillation Detectors of AugerPrime

open access: yes
At the highest energies, cosmic rays can be detected only indirectly by the extensive air showers they create upon interaction with the Earth’s atmosphere.

A Nonlinear Quantitative Model for Measuring Concentration Ratios From Raman Intensities

open access: yesJournal of Raman Spectroscopy, Volume 57, Issue 7, Page 1254-1266, July 2026.
Estimating concentration from Raman intensity ratios is complicated by cross‐contributions from overlapping peaks, causing measured ratios to deviate from the linear behavior assumed in conventional quantitative models. This nonlinear method fully accounts for cross‐contributions, allowing estimation of concentration over several orders of magnitude ...

Molecular shocks and the gamma-ray clouds of the W28 supernova remnant

open access: yes, 2017
Interstellar medium clouds in the W28 region are emitting gamma-rays and it is likely that the W28 supernova remnant is responsible, making W28 a prime candidate for the study of cosmic-ray acceleration and diffusion.

Data fusion of gamma and x‐ray spectra via Common Dimensions for soil erosion characterization

open access: yesSoil Science Society of America Journal, Volume 90, Issue 4, July/August 2026.
Abstract This study explores the synergistic application of energy dispersive x‐ray fluorescence (EDXRF) and gamma‐ray spectrometry (GRS) raw spectra to characterize soil redistribution. The evaluation employs Common Dimensions (ComDim), a multiblock non‐supervised machine‐learning technique, to identify shared latent patterns across nuclear and atomic

Assessing the Worth of Noble Gas Tracer Concentrations in Alluvial River‐Aquifer Systems Using Data Space Inversion

open access: yesWater Resources Research, Volume 62, Issue 7, July 2026.
Abstract Alluvial systems are dynamic, structurally complex environments. Groundwater that is extracted from these systems is widely used for domestic consumption. Numerical models play an important role in the management of this extraction. To provide support for decision‐making, models must assimilate data that inform the spatial and temporal ...
