Millimeter-wave CO and SiO Observations toward the Broad-velocity-width Molecular Feature CO 16.134–0.553: A Smith Cloud Scenario?

open access: yesThe Astrophysical Journal
We report the results of the CO J = 1–0 and SiO J = 2–1 mapping observations toward the broad-velocity-width molecular feature (BVF) CO 16.134–0.553 with the Nobeyama Radio Observatory 45 m telescope.

How to Imagine Educational AI: The Filling of a Pail or the Lighting of a Fire?

open access: yesEducational Theory, Volume 76, Issue 3, Page 316-338, June 2026.
Abstract Recent advances in artificial intelligence (e.g., machine learning, generative AI) have led to increased interest in its application in educational settings. AI companies hope to revolutionize teaching and learning by tailoring material to the individual needs of students, automating parts of teachers' jobs, or analyzing educational data to ...

Segmenting Superbubbles in a Simulated Multiphase Interstellar Medium Using Computer Vision

open access: yesThe Astrophysical Journal
We developed a computer vision-based methodology to achieve precise 3D segmentation and tracking of superbubbles within magnetohydrodynamic simulations of the supernova-driven interstellar medium.

Double dissociation between conduction aphasia and conduction agraphia supports a ventro‐dorsal partition of the left arcuate fasciculus

open access: yesJournal of Neuropsychology, Volume 20, Issue 2, Page 502-509, June 2026.
Abstract We identified in two awake surgery cases a postoperative double dissociation between phonological and graphemic output buffer deficits. Using lesion‐symptom mapping from ischaemic mini‐strokes and preoperative tractography, we demonstrated that the phonological (resp. graphemic) disorder fitted with ventral (resp.

Combustion and Pyrolysis EA‐IRMS Techniques to Determine the δ2H of Diamonds

open access: yesRapid Communications in Mass Spectrometry, Volume 40, Issue 10, 30 May 2026.
ABSTRACT Rationale Diamonds are generally considered to be metasomatic minerals originating from the Earth's mantle. They formed through the interaction of carbon‐bearing fluids or melts with the surrounding deep lithology. Most knowledge about the formation of diamonds comes from studying their mineral inclusions or stable isotopes.

Inverse Raman Scattering and the Diffuse Interstellar Bands: An Exploration of the Systemic Interconnections between Spontaneous and Inverse Raman Scattering and Extended Red Emission, Red Rectangle Bands, and Diffuse Interstellar Bands

open access: yesThe Astrophysical Journal
First identified in 1964, inverse Raman scattering (IRS) is a nonlinear stimulated phenomenon that induces Raman-scattered absorptions where Raman emissions would be expected.

The Physics of the Interstellar Matter [PDF]

open access: yesHighlights of Astronomy, 1974
Some of the most striking recent discoveries about interstellar matter involve molecules. It has been known for a long time that there are atoms and ions in space - mainly hydrogen and helium, of course - but also heavier elements like sodium and calcium.

Detecting Dark Objects with Plasma Microlensing by Their Gravitational Wakes

open access: yesThe Astrophysical Journal
A moving mass makes a gravitational wake in the partially ionized interstellar medium, which acts as a lens for radio-frequency light. Consequently, plasma microlensing could complement gravitational microlensing in the search for invisible massive ...
