Short-period Heartbeat Binaries from TESS Full-frame Images

The Astrophysical Journal Supplement Series
We identify 240 short-period ( P ≲ 10 days) binary systems in Transiting Exoplanet Survey Satellite data, 180 of which are heartbeat binaries. The sample is mostly a mix of A- and B-type stars and primarily includes eclipsing systems, where over 30% of ...

Identity Entanglement: Rethinking Marginality through the Intersectional, Liminal, and Antithetical

Symbolic Interaction, EarlyView.
While identity research has given sustained attention to marginality, intersectionality, and the effects of power on identity, the formal interactional dynamics through which identities are constituted remain limited. I present identity entanglement as a useful framework for better understanding and articulating the relational complexities of identity.

Light curve analysis of eclipsing binary stars using PHOEBE [PDF]

, 2018
publisherClose binary stars are important sources of astronomical information. Photometric data can be acquired from these stars using a small-aperture telescope, and the period, radius ratio, and ratio of the luminous intensities of the component stars ...

New periodic variable stars coincident with ROSAT sources discovered using SuperWASP [PDF]

, 2007
We present optical lightcurves of 428 periodic variable stars coincident with ROSAT X-ray sources, detected using the first run of the SuperWASP photometric survey. Only 68 of these were previously recognised as periodic variables.

Data privacy model using blockchain reinforcement federated learning approach for scalable internet of medical things

CAAI Transactions on Intelligence Technology, EarlyView.
Abstract Internet of Medical Things (IoMT) has typical advancements in the healthcare sector with rapid potential proof for decentralised communication systems that have been applied for collecting and monitoring COVID‐19 patient data. Machine Learning algorithms typically use the risk score of each patient based on risk factors, which could help ...

A Systematic Search for Big Dippers in ASAS-SN

The Open Journal of Astrophysics
Dipper stars are extrinsically variable stars with deep dimming events due to extended, often dusty, structures produced by a wide range of mechanisms such as collisions, protoplanetary evolution or stellar winds.

Paired CycleGAN‐based virtual staining for 3D X‐ray histology of bone‐implant systems

Journal of Synchrotron Radiation, EarlyView.
This work demonstrates virtual staining for 3D X‐ray histology using a modified CycleGAN trained on paired synchrotron radiation microtomography (SR‐µCT) and histology images of bone‐implant specimens. The method enables the generation of artificially coloured contrast resembling conventional histological staining from label‐free SR‐µCT data and is ...

Haunting the Historiography of Slaves in South Asia from the nineteenth century to the present

Gender &History, EarlyView.
ABSTRACT Using both English and Urdu‐language records, this article traces the career of a few African and Afro‐Asian women slaves in the household‐state of Awadh during the first half of the nineteenth century. Focusing on the same records, this article compares a master‐poet's recognition of the motherhood of the African and Afro‐Asian slaves to the ...
