Ubiquitous Argonium, ArH⁺, in the Diffuse Interstellar Medium [PDF]

, 2014
ArH+ is isoelectronic with HCl. The J = 1-0 and 2-1 transitions of 36ArH+ near 617.5 and 1234.6 GHz, respectively, have been identified very recently as emission lines in spectra obtained with Herschel toward the Crab Nebula supernova remnant.1 On Earth,

DMSO solvates of tert‐butylcalix[6]arene and related multisolvent structures

Acta Crystallographica Section B, EarlyView.
This study highlights how solvent properties, host–guest interaction energies and packing preferences govern the solid‐state organization of tert‐butylcalix[6]arene, a macrocycle of importance in separation, molecular recognition and supramolecular chemistry.tert‐Butylcalix[6]arene (TBC6) exhibits a rich crystal energy landscape, with structural ...

Genomic Signatures and Demographic History of the Widespread and Critically Endangered Yellow‐Breasted Bunting

Molecular Ecology, EarlyView.
ABSTRACT Population declines may have long‐term genetic consequences, including genetic erosion and inbreeding depression, which could affect species' evolutionary potential and increase their risk of extinction. Small populations are more vulnerable to genetic threats than common species, but even species with large populations can also be at risk of ...

Effect of Supernovae on the Local Interstellar Material

, 2017
A range of astronomical data indicates that ancient supernovae created the galactic environment of the Sun and sculpted the physical properties of the interstellar medium near the heliosphere.

Hamas's October 7 Attack: Analysis of an “Antagonistic” Crisis

Public Administration Review, EarlyView.
ABSTRACT The aim of the article is to interpret the Hamas attack of October 7, 2023 in light of crisis management theories, seeking to draw from this event some general lessons about the nature of crises, their determinants, and how they are managed. More specifically, the article addresses three questions: (1) Why did Israel underestimate the warning ...

Review of the anatomical basis for predicting plutonium alpha particle radiation induced osteogenic cancers

The Anatomical Record, Volume 308, Issue 12, Page 3197-3229, December 2025.
Abstract Plutonium was discovered and first synthesized in the early 1940's. Several isotopes of plutonium are used in nuclear technologies, 238Pu for heat generation and 239Pu for energy production and weapons. Both isotopes emit alpha particles, which pose a significant radiation hazard when incorporated into the body.

Neutrino oscillations in magnetically driven supernova explosions

, 2009
We investigate neutrino oscillations from core-collapse supernovae that produce magnetohydrodynamic (MHD) explosions. By calculating numerically the flavor conversion of neutrinos in the highly non-spherical envelope, we study how the explosion ...

A Small Pathbreaking Spacecraft: Giants of Space Research (Bernard Blake, Dieter Hovestadt, and Edward Stone)

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract The Solar, Anomalous, and Magnetospheric Explorer (SAMPEX) mission launched in July 1992 was the first NASA “Small Explorer” project. It had the goal to show how space missions could be developed much more rapidly than had become the situation in the 1980s and 1990s.

Radar Polarimetry in Glaciology: Theory, Measurement Techniques, and Scientific Applications for Investigating the Anisotropy of Ice Masses

Reviews of Geophysics, Volume 63, Issue 4, December 2025.
Abstract Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, associated with ice‐crystal orientation fabric (COF), or extrinsic, associated with material heterogeneity, such as bubbles, fractures, and ...
