Eigen‐Swarm: Swarm's Thermospheric Mass Density Modeling via Eigen‐Decomposition

open access: yesSpace Weather, Volume 23, Issue 7, July 2025.
Abstract Precise thermospheric mass density (TMD) prediction is essential for satellite orbital tracking, reentry calculations, and upper atmospheric processes under varying solar and magnetospheric conditions. In this paper, we construct an empirical model of TMD at 450 km altitude with accelerometer‐derived (ACC) TMD observations from the Swarm‐C ...

Self‐Consistent Optimization of Electron and Neutral Densities in a Physics‐Based Model Toward Ionosphere‐Thermosphere Forecast

open access: yesSpace Weather, Volume 23, Issue 6, June 2025.
Abstract In this study, we aimed to explore whether electron and neutral densities could be simultaneously optimized while keeping the ionosphere‐thermosphere (IT) system self‐consistent. We used ionospheric and thermospheric observations, either alone or together, as constraints to adjust uncertain parameters in a physics‐based model. Our results show

Telomere‐to‐telomere genome assembly reveals insights into the adaptive evolution of herbivore‐defense mediated by volatile terpenoids in Oenanthe javanica

open access: yesPlant Biotechnology Journal, Volume 23, Issue 6, Page 2346-2357, June 2025.
Summary Releasing large quantities of volatiles is a defense strategy used by plants to resist herbivore attack. Oenanthe javanica, a perennial herb of the Apiaceae family, has a distinctive aroma due to volatile terpenoid accumulation. At present, the complete genome and genetic characteristics of volatile terpenoids in O.

An unusual wheat insertion sequence (WIS1) lies upstream of an alpha-amylase gene in hexaploid wheat, and carries a "minisatellite" array

open access: yes, 1989
Comparison of the 5' flanking regions of three alpha-amylase genes from chromosome 6B of hexaploid wheat by heteroduplex and sequence analysis revealed the presence of a 1.6 kb stem-loop insertion sequence (WIS1) in one of them.

Multiple-locus variable-number tandem-repeat analysis of the swine dysentery pathogen, Brachyspira hyodysenteriae

open access: yes, 2010
The spirochete Brachyspira hyodysenteriae is the causative agent of swine dysentery, a severe colonic infection of pigs that has a considerable economic impact in many swine-producing countries.

Finding new human minisatellite sequences in the vicinity of long CA-rich sequences.

open access: yes, 1999
International audienceMicrosatellites and minisatellites are two classes of tandem repeat sequences differing in their size, mutation processes, and chromosomal distribution. The boundary between the two classes is not defined.

Investigation of distal repetitive sequences in the genus allium

open access: yes, 2009
PhDThe telomere is a DNA/protein structure required to maintain the ends of linear chromosomes. Usually the DNA component comprises a highly conserved tandemly repeated minisatellite sequence.

Variable tandem repeats accelerate evolution of coding and regulatory sequences

open access: yes, 2010
Genotype-to-phenotype mapping commonly focuses on two major classes of mutations: single nucleotide polymorphisms (SNPs) and copy number variation (CNV). Here, we discuss an underestimated third class of genotypic variation: changes in microsatellite and
