THE SIGNIFICANCE OF USING HIGHER ORDER POLYNOMIALS TO DESCRIBE THE (O-C) DIAGRAMS OE ECLIPSING BINARIES

Odessa Astronomical Publications, 2017
The principal aim of the present study is to underline the significance of using higher order polynomials to describe the (O-C) diagrams of eclipsing binary systems.

Free Charge Generation in Organic Photoconversion Devices–the Impact of Electrostatic Potentials

Advanced Energy Materials, EarlyView.
Free charge generation in organic photovoltaic and photodetector devices typically requires an external driving force to separate bound excitons formed upon photoexcitation. This review details how electrostatic potentials, arising from molecular charge distributions in organic semiconductors, can impact interfacial energetic landscapes and promote ...

Precision photometry with difference imaging in the WTS

EPJ Web of Conferences, 2013
The Wide Field Camera Transit Survey is a pioneer program aimed to search for extra-solar planets in the near-infrared. The standard data reduction pipeline of the program uses aperture photometry to construct the light curves. We alternatively apply the

Data‐Driven High‐Throughput Volume Fraction Estimation From X‐Ray Diffraction Patterns

Advanced Intelligent Discovery, EarlyView.
Long exposure times and the need for manual evaluation limit the use of X‐ray diffraction in high‐throughput applications. This study presents a data‐driven approach addressing both issues. HiVE (a method for High‐throughput Volume fraction Estimation) performs composition estimation for high‐noise XRD patterns produced using polychromatic emission ...

The spin─orbit alignment of five long period eclipsing binary systems

We present a joint analysis of TESS photometry and MINERVA-Australis radial velocity data for five long-period eclipsing binary systems with late-F to early-G primaries: TIC 28051929, TIC 49899799, TIC 89045042, TIC 410314066, and TIC 446872386.

Eclipsing Millisecond Pulsars with He Star Companions

The Astrophysical Journal
Eclipsing millisecond pulsars (MSPs) are a type of pulsar binaries with close orbits (≲1.0 day). They are important objects for studying the accretion history of neutron stars (NSs), pulsar winds, and the origin of isolated MSPs, etc.

A Generative AI Framework to Predict Cardiomyocyte Contraction Function From Single Static Images

Advanced Intelligent Discovery, EarlyView.
A single static hiPSC‐cardiomyocyte image is fed into a U‐Net‐GAN framework, which directly predicts a pixel‐resolved contraction heatmap without time‐lapse imaging. StyleGAN2‐generated synthetic cell–heatmap pairs augment training, improving prediction fidelity (SSIM = 0.84).

Characterization of Eclipsing Binary System EPIC 211982753 [PDF]

, 2023
We present the physical parameters of an eclipsing binary system EPIC 211982753 derived through photometric and radial velocity data modeling. We make use of photometric data from NASA's K2 mission, ASAS-SN, and 1.3-m Devasthal Fast Optical Telescope ...

3D Closed‐Loop Navigation of Magnetic Microswimmers Using Vision‐Derived Depth Feedback

Advanced Intelligent Systems, EarlyView.
A planar magnetic microswimmer is navigated in three dimensions under a standard microscope. Image defocus supplies a real‐time depth cue, and model‐predictive control with A* planning steers the body on surfaces and in free swimming. Axial position is regulated by propulsion alone, without magnetic field gradients or extra cameras.

A Photometric and Spectroscopic Investigation of 11 TESS Eclipsing Contact Binaries

The Astrophysical Journal
By cross-matching the eclipsing binary catalog provided by A. Prša et al. with Large Sky Area Multi-Object Fiber Spectroscopic Telescope medium-resolution spectra, we obtained 11 targets.
