Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

open access: yesJournal of Field Robotics, Volume 43, Issue 3, Page 1646-1660, May 2026.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Electrical spin protection and manipulation via gate-locked spin-orbit fields

open access: yes, 2014
The spin-orbit (SO) interaction couples electron spin and momentum via a relativistic, effective magnetic field. While conveniently facilitating coherent spin manipulation in semiconductors, the SO interaction also inherently causes spin relaxation.

Assessing Deposit‐Derived Pyroclastic Flow Hazard at Stromboli (Italy): 2. Probabilistic Invasion Maps

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 5, May 2026.
Abstract This study presents a new method to assess the hazard of deposit‐derived pyroclastic density currents (PDC), a critical threat on volcanic islands and on populated slopes of active volcanoes, considering the exemplary case study of Stromboli (Italy).

Transport of Water in a Transient, Impact‐Generated Atmosphere on Mercury

open access: yesJournal of Geophysical Research: Planets, Volume 131, Issue 5, May 2026.
Abstract Mercury's polar cold traps host water ice deposits that are likely populated with impact‐delivered water via Mercury's exosphere. However, Mercury's near‐sun location experiences an extremely high photodestruction rate that rapidly destroys water with a timescale of only ∼3.5 hr.

A new model of heart failure with preserved ejection fraction using external radiation therapy in male rats

open access: yesPhysiological Reports, Volume 14, Issue 9, May 2026.
Abstract Heart failure with preserved ejection fraction (HFpEF) accounts for nearly half of heart failure cases and is characterized by diastolic dysfunction, myocardial fibrosis, inflammation, and endothelial alterations. However, relevant preclinical models remain limited.

Fast dynamic voluntary contractions enhance corticospinal facilitation of the human diaphragm: A transcranial magnetic stimulation study

open access: yesPhysiological Reports, Volume 14, Issue 9, May 2026.
Abstract In limb muscles, corticospinal excitability is modulated by motor context, with greater facilitation during movement initiation and dynamic contractions than during sustained isometric activation. Whether this applies to the human diaphragm remains uncertain, given the hybrid automatic‐voluntary control and continuous activity of respiratory ...
