Transposable Element Dynamics Drive the Genomic Evolution and Phenotypic Diversification of Allotetraploid Common Carp

open access: yesAdvanced Science, EarlyView.
By integrating 516 whole‐genome resequencing datasets and 236 transcriptomes of allotetraploid common carp, this study establishes the first population‐scale atlas of transposable element (TE) variation in teleost species. TE bursts, relaxed purifying selection, and lineage‐specific loss of ancient insertions shape genome evolution and phenotypic ...

The Araucaria project. Precise physical parameters of the eclipsing binary IO Aquarii [PDF]

open access: yes, 2015
Aims. Our aim is to precisely measure the physical parameters of the eclipsing binary IO Aqr and derive a distance to this system by applying a surface brightness – colour relation.

Line of sight errors in eclipsing binary stars

open access: yes, 2022
This paper will illustrate the line of sight errors in eclipsing binary stars. Due to this error, the eclipsing binary stars will not actually along be along the line of sight when the observer sees them as eclipsing. This is due to the longer time taken

Modelling of W UMa-type variable stars

open access: yesSouth African Journal of Science, 2009
W Ursae Majoris (W UMa)-type variable stars are over-contact eclipsing binary stars. To understand how these systems form and evolve requires observations spanning many years, followed by detailed models of as many of them as possible.

KM UMa: An Active Short-period Detached Eclipsing Binary in a Hierarchical Quadruple System

open access: yesThe Astrophysical Journal
The first detailed photometric and spectroscopic analysis of the G-type eclipsing binary KM UMa is presented, which indicates that the system is a short-period detached eclipsing binary.

Thermal Shifts Dominate Single‐Gene Responses to Transcription‐Targeting Antibiotics

open access: yesAdvanced Science, EarlyView.
Thermal shifts reshape bacterial responses to transcription‐targeting antibiotics. In E. coli, temperature can dominate antibiotic‐induced genome‐wide expression, particularly outside 30°C–39°C, through changes in adenosine triphosphate (ATP), nucleoid organization, and drug‐target engagement.

An Engineered Supramolecular Pathway for Enhanced Electrochemiluminescence

open access: yesAdvanced Science, EarlyView.
A supramolecular electrochemiluminescent (ECL) system is presented in which cucurbit[7]uril (CB7) is covalently linked to [Ru(bpy)3]2+, forming a recognition‐responsive emitter. Host‒guest preorganization of tri‐n‐propylamine enables intramolecular ECL, boosting intensity by 162% compared to the standard system.

Eclipse Depth Variations in Seven Eclipsing Binaries as Observed by KELT and TESS

open access: yesThe Astronomical Journal
A set of eclipsing binary systems exhibit a changing inclination over time due to the gravitational influence of a third stellar companion. These changing inclinations manifest in photometric observations over time as eclipse depth variations.

LigHTS: Biomimetic Hydrogel Photo‐Fabrication for Imaging‐Based Ultra‐High‐Throughput Screening

open access: yesAdvanced Science, EarlyView.
LigHTS removes a key bottleneck for ultra‐high‐throughput screening (UHTS) by enabling biomimetic hydrogel microenvironments to be manufactured directly in standard multiwell plates. A single, collimated UV exposure with formulation‐tuned light penetration patterns an entire plate with UHTS‐grade uniformity (<20% CV), producing structured GelMA films ...

A Note on the Physical Quantities of Eclipsing Binary Stars [PDF]

open access: yes, 2016
publisherIn the research activities of high school students, they derive the period of luminosity variation from the light curve of eclipsing binary stars and often consider the aspects of the eclipsing binary stars in phenomenological terms. In addition
