Migrating and Nonmigrating Neutral Mass Density Tides From GRACE‐FO Observations for Solar Minimum Conditions

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract This study presents the migrating and nonmigrating thermospheric neutral mass density tides from the Gravity Recovery And Climate Experiment Follow‐On (GRACE‐FO) observations under solar minimum conditions (year 2020). The observed densities are first mapped to a reference altitude of 500 km using an empirical model (NRLMSIS 2.0) to remove the

Evaluation and selection of tandem repeat loci for a Brucella MLVA typing assay

BMC Microbiology, 2006
Background The classification of Brucella into species and biovars relies on phenotypic characteristics and sometimes raises difficulties in the interpretation of the results due to an absence of standardization of the typing reagents.

Unfolding of quadruplex structure in the G-rich strand of the minisatellite repeat by the binding protein UP1 [PDF]

Proceedings of the National Academy of Sciences, 2002
The mouse hypervariable minisatellite (MN) Pc-1 consists of tandem repeats of d(GGCAG) and flanked sequences. We have previously demonstrated that single-stranded d(GGCAG) n folds into the intramolecular folded-back quadruplex structure under physiological conditions.

Orbital Decay of the Three SNIPE CubeSats During the Super Geomagnetic Storm in May 2024

Space Weather, Volume 24, Issue 8, August 2026.
Abstract The Mother's Day (Gannon) geomagnetic superstorm of May 2024 produced extreme thermospheric heating and expansion, resulting in enhanced atmospheric drag on low Earth orbiting (LEO) satellites. We investigate storm‐time thermospheric drag and density variability using three satellites of the Small‐scale magNetospheric and Ionospheric Plasma ...

Analysis of a c₀t-1 library enables the targeted identification of minisatellite and satellite families in Beta vulgaris

BMC Plant Biology, 2010
Background Repetitive DNA is a major fraction of eukaryotic genomes and occurs particularly often in plants. Currently, the sequencing of the sugar beet (Beta vulgaris) genome is under way and knowledge of repetitive DNA sequences is critical for the ...

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

Geophysical 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.

A novel minisatellite repeat expansion identified at FRA16B in a Japanese carrier.

Genes & Genetic Systems, 2000
Previously, the allelic expansion of a 33-bp AT-rich minisatellite repeat has been reported to cause FRA16B, a distamycin A-inducible fragile site. Here, we identified a novel 35-bp minisatellite repeat at FRA16B in a Japanese carrier. The nucleotide sequence of the 35-bp minisatellite was highly AT-rich and nearly identical to the 33-bp one but with ...

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

AGU 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 ...
