Response of Topside Ionospheric Electron Density During Solar Flares Using 2014–2024 Swarm Satellite Measurements

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract This paper presents a global statistical investigation into the topside ionosphere electron density response to X‐class solar flares during geomagnetically quiet conditions (Kp ≤ $\mathit{\le }$ 2) using Swarm satellites (462–511 km) data from 2014 to 2024.

The mitochondrial DNA markers for distinguishing Phalaenopsis species and revealing maternal phylogeny

open access: yesBiologia Plantarum, 2016
Moth orchids (Phalaenopsis) are among the top-traded blooming potted plants in the world. To explore mitochondrial DNA (mtDNA) markers for species identification, we located simple sequence repeats in the mtDNA of Phalaenopsis aphrodite subsp.

IGS Minisatellites Useful for Race Differentiation in Colletotrichum lentis and a Likely Site of Small RNA Synthesis Affecting Pathogenicity. [PDF]

open access: yesPLoS ONE, 2015
Colletotrichum lentis is a fungal pathogen of lentil in Canada but rarely reported elsewhere. Two races, Ct0 and Ct1, have been identified using differential lines. Our objective was to develop a PCR-probe differentiating these races.

Latitudinal Discrepancy Between Thermospheric Density and Temperature Associated With Neutral Composition Effect

open access: yesGeophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract In this study, multi‐source thermospheric observations and TIEGCM simulations were used to explore the latitudinal variations of thermospheric temperature and total mass density at equinoxes. At nighttime, temperature and density exhibit consistent latitudinal patterns, with higher values at high latitudes.

Effects of habitat fragmentation on the Eurasian badger (<em>Meles meles</em>) subpopulations in Denmark

open access: yesHystrix, the Italian Journal of Mammalogy, 2001
<strong>Abstract</strong> Genetic variation in five populations of the Eurasian badger from Denmark was screened, using the hyper-variable minisatellite DNA probe 33.15. Very low genetic variability was found within populations. This lack of

Isolation and Characterization of Mouse Minisatellites

open access: yesGenomics, 1998
Minisatellites provide the most informative system for analyzing processes of tandem repeat turnover in humans. However, little is known about minisatellites and the mechanisms by which they mutate in other species. To this end, we have isolated and characterized 76 endogenous mouse VNTRs.

First Results of a New Inversion Tool for Thermospheric Neutral Mass Density Computations During Severe Geomagnetic Storms

open access: yesAGU Advances, Volume 7, Issue 3, June 2026.
Abstract In Low Earth Orbit (LEO), atmospheric drag is the dominant source of trajectory prediction error below approximately 700 km altitude, primarily due to inaccuracies in thermospheric density models. This work presents a method for temporally deconvolving Energy Dissipation Rates (EDRs) to produce single‐satellite density estimates, which can be ...

Non-Canonical G-quadruplexes cause the hCEB1 minisatellite instability in Saccharomyces cerevisiae

open access: yeseLife, 2017
G-quadruplexes (G4) are polymorphic four-stranded structures formed by certain G-rich nucleic acids in vitro, but the sequence and structural features dictating their formation and function in vivo remains uncertain.

Advancing Heliophysics and Space Weather Modeling Through Open Science

open access: yesSpace Weather, Volume 24, Issue 6, June 2026.
Abstract We present a community‐wide effort to develop a strategy and action plan to advance heliophysics and space weather modeling through open science. While open science has the potential to enhance the quality and pace of scientific discovery, its application to scientific modeling requires more careful consideration regarding open data and open ...
