Powers That Be: An Adventure in Metaphysics

Philosophical Investigations, EarlyView.
ABSTRACT This paper is an investigation into the increasingly popular trend amongst philosophers on the metaphysics of powers, exemplified by the statement: ‘To be real is to possess a power to affect (or to be affected by) other things’. First, I briefly trace the history of this idea (from the Eleatic dialectic of ancient times to present day quantum

Application of muon tomography in bauxite exploration

Journal of Applied Physics
Muon-based imaging, utilizing radiographic and tomographic techniques, is a powerful tool for detecting subsurface structures based on density contrasts. Unlike conventional geophysical methods, which are influenced by subsurface material properties, muography maps density along nearly straight muon paths, enabling high-resolution imaging even of small

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 ...

Muon tomography: Plans for observations in the Lesser Antilles

Earth, Planets and Space, 2010
The application of muon tomography to monitor and image the internal structure of volcanoes in the Lesser Antilles is discussed. Particular focus is directed towards the three volcanoes that fall under the responsibility of the Institut de Physique du Globe of Paris, namely La Montagne Pelee in Martinique, La Soufriere in Guadeloupe, and the Soufriere ...

Novel Muon Tomography Detector for the Pyramids

Journal of Advanced Instrumentation in Science, 2022
Cosmic-ray muons which impinge upon the Earth’s surface can be used to image the density of geologi-cal and man-made materials located above a muon detector. The detectors used for these measurements must be capable of determining the muon rate as a function of the angle of incidence.

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

Geant4 simulation study of low-Z material detection using muon tomography [PDF]

, 2023
Traditional X-ray scanning systems for cargo use ionising radiation which can be harmful to operators and the environment and requires shielding. Fully passive muon tomography is a promising alternative or a complementary approach to X-ray scanners. Muon
