Low-altitude measurements of 2–6 MeV electron trapping lifetimes at 1.5 ≤ L ≤ 2.5 [PDF]

, 2007
During the Halloween Storm period (October–November 2003), a new Van Allen belt electron population was powerfully accelerated. The inner belt of electrons formed in this process decayed over a period of days to years. We have examined quantitatively the

Fluctuation of Lower Ionosphere Associated with Energetic Electron Precipitations during a Substorm

Atmosphere, 2021
In this paper, using the combined observations of the NOAA 16, LANL-01A, IMAGE satellites, VLF radio wave, and ground-based riometers, we study the fluctuation of lower ionosphere-associated precipitating energetic electrons during a geomagnetic storm on

Energetic, relativistic and ultra-relativistic electrons: Comparison of long-term VERB code simulations with Van Allen Probes measurements [PDF]

, 2015
In this study, we compare long-term simulations performed by the Versatile Electron Radiation Belt (VERB) code with observations from the Magnetic Electron Ion Spectrometer and Relativistic Electron-Proton Telescope instruments on the Van Allen Probes ...

James' Submodule Theorem and the Steinberg Module [PDF]

, 2017
James' submodule theorem is a fundamental result in the representation theory of the symmetric groups and the finite general linear groups. In this note we consider a version of that theorem for a general finite group with a split $BN$-pair.

Modulation of Energetic Electron Precipitation Driven by Three Types of Whistler Mode Waves

Geophysical Research Letters, 2023
Precipitation into the Earth's atmosphere due to pitch angle scattering by plasma waves has been recognized as one of the major loss mechanisms for energetic electrons.

Innate Immune Reprogramming Mediated by Endogenous Retroelement Dysregulation Drives Multiple Sclerosis Progression

Annals of Clinical and Translational Neurology, EarlyView.
Epigenetic reprogramming in hematopoietic stem and progenitor cells (HSPCs) and downstream myeloid cells, mediated by H3.3 downregulation and endogenous retroelement (ERE) overexpression, contributes to the progression of multiple sclerosis (MS). ABSTRACT Background Skewed myelopoiesis in the bone marrow has been identified as a key driver of multiple ...

Comparisons of Auroral Hiss Spectra Observed at Syowa and Mizuho Stations (c. Wave-Particle Interactions in the Magnetosphere) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)

Antarctic Record, 1980
Simultaneous observations of auroral hiss emissions have been carried out at Syowa and Mizuho Stations. The intensity of auroral hiss emissions was different from case by case at the two stations. However the spectral shapes of hiss emissions obtained at

Dual Satellite Observations of Auroral Hiss and Saucer Emissions above the Southern Auroral Zone [PDF]

, 1981
Global distributions of auroral hiss and VLF saucer emissions have been examined by using VLF data obtained from the three satellites, EXOS-A, ISIS-1 and -2. These VLF data were received at Syowa Station in Antarctica.

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

Advanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Supporting the learning of deaf students in higher education: a case study at Sheffield Hallam University [PDF]

, 1997
This article is an examination of the issues surrounding support for the learning of deaf students in higher education (HE). There are an increasing number of deaf students attending HE institutes, and as such provision of support mechanisms for these ...
