Detecting extrasolar moons akin to solar system satellites with an orbital sampling effect [PDF]
The Astrophysical Journal, 2014, Vol. 787, id 14 (15 pp), 2014 Despite years of high accuracy observations, none of the available theoretical techniques has yet allowed the confirmation of a moon beyond the solar system. Methods are currently limited to masses about an order of magnitude higher than the mass of any moon in the solar system.

Sains Malaysiana, 2020 Many astronomers have studied lunar crescent visibility throughout history. Its importance is unquestionable, especially in determining the local Islamic calendar and the dates of important Islamic events. Different criteria have been used to predict the

Closing the gap in plan quality: Leveraging deep‐learning dose prediction for adaptive radiotherapy
Journal of Applied Clinical Medical Physics, EarlyView.Abstract Purpose Balancing quality and efficiency has been a challenge for online adaptive therapy. Most systems start the online re‐optimization with the original planning goals. While some systems allow planners to modify the planning goals, achieving a high‐quality plan within time constraints remains a common barrier.

Effects of the evolving early Moon and Earth magnetospheres
Frontiers in Astronomy and Space Sciences, 2023 Recently it has been identified that our Moon had an extensive magnetosphere for several hundred million years soon after it was formed when the Moon was within 20 Earth Radii (RE) from the Earth.

Advanced Functional Materials, EarlyView.Effective electron transfer and stable enzyme immobilization, both between enzymes and host electrodes as well as between adjacent enzymes, are crucial for optimizing the biofuel cell (BFC) performance. Recently, efforts have focused on integrating these strategies with porous host electrodes.

Advanced Functional Materials, EarlyView.A laser‐driven strategy enables precise microstructural modulation of Mo₂C, achieving nanoscale grain control (15.6 ± 5 nm) and an ultrahigh grain boundary density (130 µm−1). Moreover, high‐angle grain boundaries enhance active sites, facilitate electron transport, and optimize hydrogen adsorption kinetics, significantly reducing overpotential.

What are we reading? Hot Topics and Authorship in Ecology Literature Across Decades
The Bulletin of the Ecological Society of America, Volume 104, Issue 1, January 2023., 2023 Abstract As the field of ecology evolves, analyses synthesizing trends in key topics addressed over the decades can provide historical context for the development of novel theories and methods, identify “hot topics” over time, and guide future research directions.

Global Instability of Exo-Moon System Triggered by Photo-Evaporation [PDF]
, 2016 Many exoplanets have been found in orbits close to their host stars and thus they are subject to the effects of photo-evaporation. Previous studies have shown that a large portion of exoplanets detected by the Kepler mission have been significantly eroded by photo-evaporation.
