Independent analysis of μδ data of ILS and INDLS catalogs to obtain the spin of the bright Gaia DR2 reference frame [PDF]

open access: yesSerbian Astronomical Journal, 2021
The Gaia DR2 reference frame should be without relative rotation to the quasars (QSOs) and consistent with the International Celestial Reference System (ICRS).

CTHP: Selection for adoption of open‐source bioinformatics software based on a customised ISO 25010 quality model, three‐way decision and Delphi hierarchy process

open access: yesIET Software, Volume 17, Issue 4, Page 496-508, August 2023., 2023
A customised decision method for evaluation, comparison, and adoption of the Open Source Software (OSS) frameworks is proposed in this study. The important attributes of a framework such as reliability, maintainability, and documentation concerning project requirements and priorities can be obtained by customising the ISO 9126 quality model in terms of

Prediction of protein–protein interactions using sequences of intrinsically disordered regions

open access: yesProteins: Structure, Function, and Bioinformatics, Volume 91, Issue 7, Page 980-990, July 2023., 2023
Abstract Protein–protein interactions (PPIs) play a crucial role in numerous molecular processes. Despite many efforts, mechanisms governing molecular recognition between interacting proteins remain poorly understood and it is particularly challenging to predict from sequence whether two proteins can interact.

The hyperluminous X‐ray source population

open access: yesAstronomische Nachrichten, Volume 344, Issue 4, May 2023., 2023
Abstract We have recently published a catalog of 1843 candidate ultraluminous X‐ray sources (ULXs). This is the largest catalog of ULXs to date and was built by cross‐correlating recent serendipitous source catalogs from the XMM‐Newton, Swift, and Chandra observatories with a large sample of galaxies, primarily from HyperLEDA.

Harnessing Unresolved Lensed Quasars: The Mathematical Foundation of the Fluctuation Curve

open access: yesThe Astrophysical Journal, 2023
Strong gravitational lensed quasars (QSOs) have emerged as powerful and novel cosmic probes as they can deliver crucial cosmological information, such as a measurement of the Hubble constant, independent of other probes. Although the upcoming LSST survey

Multicellular Quadruple Colorectal Cancer Spheroids as an In Vitro Tool for Antiangiogenic Potential Evaluation of Nanoparticles

open access: yesAdvanced Therapeutics, Volume 6, Issue 4, April 2023., 2023
Colorectal cancer occupies the third position worldwide in terms of incidence and is the second cause of cancer‐related deaths. Preclinical models that mimic the complexity of colorectal cancer are explored in the literature. This study takes an unprecedented approach to explore a quadruple co‐culture model to evaluate the antiangiogenic activity of ...

A Bias-free Cosmological Analysis with Quasars Alleviating H 0 Tension

open access: yesThe Astrophysical Journal Supplement Series, 2023
Cosmological models and their parameters are widely debated because of theoretical and observational mismatches of the standard cosmological model, especially the current discrepancy between the value of the Hubble constant, H _0 , obtained by Type Ia ...

High-z Universe Probed via Lensing by QSOs (HULQ). I. Number Estimates of QSO–QSO and QSO–Galaxy Lenses

open access: yesThe Astrophysical Journal, 2020
Abstract It is unclear how galaxies and their central supermassive black holes coevolve across cosmic time, especially for the nonlocal universe (z ≳ 0.5). The High-z Universe probed via Lensing by QSOs project proposes to utilize quasi-stellar object (QSO) host galaxies acting as gravitational lenses (QSO lenses) to investigate this ...

Effect of the metallicity of the intergalactic medium in the Lyman‐α forest correlation function

open access: yesAstronomische Nachrichten, Volume 344, Issue 1-2, January-February 2023., 2023
Abstract The Lyman‐α (Lyα) forest allows to constraint cosmological parameters at redshifts above 1.8$$ 1.8 $$ using the technique of standard rulers determined by baryon acoustic oscillations. This makes it an important tracer for the study of the universe at high redshift.
