The Evolutionary Statuses of Solar Type Detached Eclipsing Binary Stars [PDF]

Journal of Astronomy and Space Sciences, 2012
We presented fundamental stellar parameters and evolutionary statuses of six solar type detached eclipsing binaries whose masses are in the range of 0.97-1.43 M⊙. EK Cep and FL Lyr belong to the zero age main sequence.

Eclipsing binaries in extrasolar planet transit surveys: the case of SuperWASP [PDF]

Mon.Not.Roy.Astron.Soc. 367 (2006) 1103-1112, 2006
Using a comprehensive binary population synthesis scheme, we investigate the statistical properties of a sample of eclipsing binaries that is detectable by an idealised extrasolar planet transit survey with specifications broadly similar to those of the SuperWASP (Wide Angle Search for Planets) project.

Evaluation of AI‐based auto‐contouring tools in radiotherapy: A single‐institution study

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Background Accurate delineation of organs at risk (OARs) is crucial yet time‐consuming in the radiotherapy treatment planning workflow. Modern artificial intelligence (AI) technologies had made automation of OAR contouring feasible. This report details a single institution's experience in evaluating two commercial auto‐contouring software ...

The Mass and Angular Momentum Relation of Eclipsing Binaries [PDF]

Journal of Astronomy and Space Sciences, 1998
With a total 3780 eclipsing binary system in the Catalogue of Approximate Photometric and Absolute Elements of Eclipsing Variable Stars by Svechnikov & Kuznetsova (1990), the empirical relations between the systemic mass and orbital angular momentum have

Light Curves and Period Analysis of Beta Lyrae Stars

The Astronomical Journal, 2023
We present the light-curve period analysis of 36 Beta Lyrae stars from the OMC Archive. We check the reference period of the sample by applying the phase dispersion minimization periodogram.

Photodynamical Modeling of the Compact, Multiply Eclipsing Systems KIC 5255552, KIC 7668648, KIC 10319590, EPIC 220204960 [PDF]

arXiv, 2023
We present photodynamical models of four eclipsing binary systems that are members of higher-order multiple systems. We provide some radial velocities measurements and use recent TESS data for three of the systems. KIC 7668648 consists of an eclipsing binary (P=27.8 d) with late-type stars that has a low-mass star on a roughly coplanar outer orbit (P ...

THE G+M ECLIPSING BINARY V530 ORIONIS: A STRINGENT TEST OF MAGNETIC STELLAR EVOLUTION MODELS FOR LOW-MASS STARS [PDF]

, 2014
We report extensive photometric and spectroscopic observations of the 6.1 day period, G+M-type detached double-lined eclipsing binary V530 Ori, an important new benchmark system for testing stellar evolution models for low-mass stars.

Enhanced dose prediction for head and neck cancer artificial intelligence‐driven radiotherapy based on transfer learning with limited training data

Journal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose Training deep learning dose prediction models for the latest cutting‐edge radiotherapy techniques, such as AI‐based nodal radiotherapy (AINRT) and Daily Adaptive AI‐based nodal radiotherapy (DA‐AINRT), is challenging due to limited data.

The XO Planetary Survey Project - Astrophysical False Positives

, 2010
Searches for planetary transits find many astrophysical false positives as a by-product. There are four main types analyzed in the literature: a grazing-incidence eclipsing binary star, an eclipsing binary star with a small radius companion star, a blend

Nanoengineering of Chitosan Sponges Via Atomic Layer Deposition of ZnO for Water Remediation Technologies

Advanced Materials Interfaces, EarlyView.
Chitosan sponges are modified with ZnO through atomic layer deposition (ALD) to enhance water remediation. Characterization reveals the growth of defective ZnO, which improves the water stability of the sponges. The material's effectiveness is demonstrated through the removal of Direct Blue 78 dye and the photocatalytic degradation of Naproxen ...
