Statistical Auroral Absorption Model Parameterized by AE Index

Journal of Geophysical Research: Space Physics, Volume 131, Issue 1, January 2026.
Abstract Energetic electron precipitation, often in association with enhanced geomagnetic activity, leads to increased D‐region ionization in the auroral region causing auroral absorption. A statistical auroral absorption model is presented for high‐latitudes (poleward of 50° magnetic latitude) based on data collected from 2010 to 2019 from 13 wide ...

RDA, or, The Long Journey of the Catalog to the Digital Age

JLIS.it, 2016
RDA was created in response to complaints about the Anglo-American Cataloguing Rules, especially the call for a more international, principle-based content standard that takes the perspective of the conceptual models of FRBR (Functional Requirements for ...

Wall conditions in WEST during operations with a new ITER grade, actively cooled divertor

Nuclear Materials and Energy
Future fusion reactors like ITER and DEMO will have all-tungsten (W) walls and long pulses. These features will make wall conditioning more difficult than in most of the existing devices.

Two-temperature Steady State Thermodynamics for a Radiation Field

, 2005
A candidate for a consistent steady state thermodynamics is constructed for a radiation field in vacuum sandwiched by two black bodies of different temperatures.

Cooling of a mirror by radiation pressure [PDF]

, 1999
We describe an experiment in which a mirror is cooled by the radiation pressure of light. A high-finesse optical cavity with a mirror coated on a mechanical resonator is used as an optomechanical sensor of the Brownian motion of the mirror.

Mozambique's Colonial‐Era Non‐Human Primate Collection at the National Museum of Natural History and Science of Lisbon: Taxonomy, Provenance, and Historical Context

American Journal of Biological Anthropology, Volume 188, Issue 4, December 2025.
ABSTRACT Objectives This study reviews Mozambique's non‐human primate collection housed at the National Museum of Natural History and Science (MUHNAC) in Lisbon. The collection originates from the Zoological Missions of Mozambique (1948 and 1955) carried out under Portuguese colonial administration. The objectives of this work were to: i.

The time step constraint in radiation hydrodynamics

, 2019
Explicit radiation hydrodynamic simulations of the atmospheres of massive stars and of convection in accretion discs around white dwarfs suffer from prohibitively short time steps due to radiation.

An Evolutionary Mosaic Challenges Traditional Monitoring of a Foundation Species in a Coastal Environment—The Baltic Fucus vesiculosus

Molecular Ecology, Volume 34, Issue 23, December 2025.
ABSTRACT During periods of environmental change, genetic diversity in foundation species is critical for ecosystem function and resilience, but it remains overlooked in environmental monitoring. In the Baltic Sea, a key species for monitoring is the brown seaweed Fucus vesiculosus, which forms sublittoral 3D habitats providing shelter and food for fish

Three Dimensional Hydrodynamic Simulations of Multiphase Galactic Disks with Star Formation Feedback: I. Regulation of Star Formation Rates

, 2013
The energy and momentum feedback from young stars has a profound impact on the interstellar medium (ISM), including heating and driving turbulence in the neutral gas that fuels future star formation.
