L‐Probe: New Approach for Spike Removal in Raman Hyperspectral Imaging Based on Local Prominence Peak Filtering

Journal of Chemometrics, Volume 40, Issue 8, August 2026.
ABSTRACT Raman hyperspectral imaging is an indispensable analytical technique that can provide simultaneous chemical and spatial information of a sample, enabling a higher comprehension and sampling of the analyzed material. However, a known challenge in processing large hyperspectral Raman datasets is the effective removal of spurious, high‐intensity ...

ML-Based Dual View Object Localization From Straight and Scattered Muon Rays

IEEE Access
Imaging methods based on the scattering of atmospheric muons use the natural flux of muons produced in the atmosphere. Muon tomography (MT) has emerged as a promising technology in various applications, including detecting contraband in border security ...

Spatial variability of denudation rates and transient landscape adjustment in low‐deforming mountains (the Strengbach catchment, Vosges Mountains, France)

Earth Surface Processes and Landforms, Volume 51, Issue 8, August 2026.
Erosion across the landscape is described at first order by a limited number (nine) of homogenous geomorphological and lithological domains. Using a dense set of basin wide denudation rates, it is possible to retrieve the contribution of each litho‐morpho‐domains as a function of their respective surface.

Gram‐Scale Synthesis of Perdeuterated Paracetamol

Journal of Labelled Compounds and Radiopharmaceuticals, Volume 69, Issue 10-11, August‐September 2026.
We report the synthesis of perdeuterated paracetamol on a multigram scale with an average deuterium incorporation of > 93% and no less than 78% at any individual position. ABSTRACT The synthesis of deuterated compounds is a major stumbling block in the field of neutron total scattering on disordered materials.

Latitude Survey of Neutrons and Muons to Determine Cosmic Ray Neutron Sensing Yield Functions

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract Cosmic Ray Neutron Sensing (CRNS) is a ground‐based technique that utilizes epithermal neutron measurements as a proxy for environmental hydrogen content. Similarly to other ground‐based cosmic ray detectors (e.g., neutron monitors), CRNS detectors are affected by the solar cycle and space weather events.

Simulation Study of 3D Imaging Method for Low and Medium Atomic Number Objects at Small Scale by Cosmic-ray Muon

Yuanzineng kexue jishu, 2022
Cosmic-ray muon imaging is a new non-destructive technique that uses highly penetrating natural muon to reconstruct objects with high atomic number (Z) or subjects hidden in something by applying muon scattering or transmission technique, respectively ...

Muon Tomography sites for Colombian volcanoes

Annals of Geophysics, 2020
By using a very detailed simulation scheme, we have calculated the cosmic ray background flux at 13 active Colombian volcanoes and developed a methodology to identify the most convenient places for a muon telescope to study their inner structure. Our simulation scheme considers three critical factors with different spatial and time scales: the geo ...

Status of the PRISM FFAG Design for the Next Generation Muon-to-Electron Conversion Experiment [PDF]

, 2012
The PRISM Task Force continues to study high intensity and high quality muon beams needed for next generation lepton flavour violation experiments. In the PRISM case such beams have been proposed to be produced by sending a short proton pulse to a ...

Study of prompt gamma and neutron emission for real‐time range verification in proton and carbon‐ion therapy

Medical Physics, Volume 53, Issue 7, July 2026.
Abstract Background Accurate range verification is crucial in hadrontherapy to fully exploit the ballistic advantages of charged particles and prevent damage to healthy tissues. Among the proposed approaches, prompt gamma imaging (PGI) has emerged as an effective technique for real‐time monitoring, but its performance is limited by the intense neutron ...

A Dialogue on Revolutions and Revolutionaries in Science: A Perspective From Quantum Mechanics

Natural Sciences, Volume 6, Issue 3, July 2026.
ABSTRACT We discuss the notions of scientific revolutions and revolutionaries in the context of the Relativity Revolution and of the First, Second, and Third Quantum Revolutions. We conclude that at the core of the question of what qualifies as a revolution and revolutionary is an assessment of the gradients of knowledge accumulation over time, both at
