Turko-Mongols of Central and Inner Asia: The Pleiades as Part of Folk Knowledge

Oriental Studies
Introduction. The The Pleiades star cluster was the most important asterism in the life of Inner and Central Asian nomads — of all the astral objects visible in the night sky — as a guide in time and space during the hours of darkness.

IN-SYNC. VII. Evidence for a decreasing spectroscopic binary fraction from 1 to 100 Myr within the IN-SYNC sample

, 2017
We study the occurrence of spectroscopic binaries in young star-forming regions using the INfrared Spectroscopy of Young Nebulous Clusters(IN-SYNC) survey, carried out in SDSS-III with the APOGEE spectrograph. Multi-epoch observations of thousands of low-

Affordable phenomics: Expanding access to enhancing genetic gain in plant breeding

The Plant Phenome Journal, Volume 8, Issue 1, December 2025.
Abstract Plant breeders need to evaluate large breeding populations rapidly and accurately to identify and assess genetic variation responsible for many traits, including yield, quality, resistance, and climate resilience. Although advanced molecular tools, including marker‐assisted selection, genomic selection, and gene editing, are being used to ...

Li I and K I Scatter in Cool Pleiades Dwarfs [PDF]

, 2010
We utilize high-resolution (R~60,000), high S/N (~100) spectroscopy of 17 cool Pleiades dwarfs to examine the confounding star-to-star scatter in the 6707 Li I line strengths in this young cluster.

What Was Homer Honing in the Odyssey?

Perspectives of Earth and Space Scientists, Volume 6, Issue 1, December 2025.
Abstract We summarize the data provided in Homer's the Odyssey concerning Odysseus' journey and suggest a completely new view of what was Homer trying to convey to us. We suggest that Homer was honing the idea of synergy between rules (determinism) and chance (randomness), an idea deeply rooted in natural processes as well in mathematics.

Contribution de l'imagerie Pléiades à la cartographie rapide des dégâts suite à des catastrophes majeures: retours d'expériences après deux ans d'actions de cartographie rapide localisées en Asie, en Afrique, en Europe et aux Caraïbes

Revue Française de Photogrammétrie et de Télédétection, 2015
Le lancement des deux satellites Pléiades 1A et 1B fin 2011 et 2012 a permis à la France de se doter de nouvelles capacités d'acquisition d'images optiques à très haute résolution, dans le domaine particulier de la gestion des crises mais aussi plus ...

AB Doradus C: Age, Spectral Type, Orbit, and Comparison to Evolutionary Models

, 2005
We expand upon the results of Close et al. 2005 regarding the young, low-mass object AB Dor C and its role as a calibration point for theoretical tracks. We present an improved spectral reduction and a new orbital solution with two additional epochs. Our

Angular Momentum Evolution of Stars in the Orion Nebula Cluster [PDF]

, 2001
(Abridged) We present theoretical models of stellar angular momentum evolution from the Orion Nebula Cluster (ONC) to the Pleiades and the Hyades. We demonstrate that observations of the Pleiades and Hyades place tight constraints on the angular momentum

Excitation Energy Transfer between Porphyrin Dyes on a Clay Surface: A Study Employing Multifidelity Machine Learning

Advanced Theory and Simulations, Volume 8, Issue 11, November 2025.
Inspired by natural light‐harvesting systems, this study computationally investigates a synthetic antenna by arranging cationic free‐base porphyrin molecules on an anionic clay surface. Using a multiscale quantum mechanics/molecular mechanics (QM/MM) approach combined with a multifidelity machine learning method, excitation energies are predicted ...
