GALACTIC AND EXTRAGALACTIC SUPERNOVA REMNANTS AS SITES OF PARTICLE ACCELERATION
Acta Polytechnica, 2013 Supernova remnants, owing to their strong shock waves, are likely sources of Galactic cosmic rays. Studies of supernova remnants in X-rays and gamma rays provide us with new insights into the acceleration of particles to high energies. This paper reviews

Potential for Supernova Neutrino Detection in MiniBooNE
, 2002 The MiniBooNE detector at Fermilab is designed to search for $\nu_\mu \to \nu_e$ oscillation appearance at $E_\nu \sim 1 {\rm GeV}$ and to make a decisive test of the LSND signal.

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 ...

The Self-Calibrating Hubble Diagram
, 2012 As an increasing number of well measured type Ia supernovae (SNe Ia) become available, the statistical uncertainty on w has been reduced to the same size as the systematic uncertainty.

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 ...

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.

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.

Supernova remnant S147 and its associated neutron star(s)
, 2005 The supernova remnant S147 harbors the pulsar PSR J0538+2817 whose characteristic age is more than an order of magnitude greater than the kinematic age of the system (inferred from the angular offset of the pulsar from the geometric center of the ...

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 ...
