Multi-band neural network classification of ZTF light curves as LSST proxies

Astronomy & Astrophysics
Context. Current and near-future sky survey programmes, such as the Legacy Survey of Space and Time (LSST) of the Vera C. Rubin Observatory, will produce vast amounts of data that will need new techniques to process them on reasonable timescales. Machine-

Interpreting the effects of DNA polymerase variants at the structural level

Molecular Oncology, EarlyView.
Using MAVISp and molecular dynamics simulations, we analyzed over 60 000 missense variants in POLE and POLD1 from ClinVar, COSMIC, cBioPortal, and saturation mutagenesis. Identified mechanistic indicators, including stability, binding, and long‐range, enable structural interpretation, providing ACMG‐like evidence for possible reclassification of VUS ...

Variable stars toward the bulge of M 31: the AGAPE catalogue [PDF]

, 2004
journal articleWe present the AGAPE astrometric and photometric catalogue of 1579 variable stars in a 14\u27 × 10\u27 field centred on M 31. This work is the first survey devoted to variable stars in the bulge of M 31. The R magnitudes of the objects and

Establishing Baselines for Six Short-period δ Scuti Variables

The Astronomical Journal
As part of our variable star follow-up program, we have examined a number of stars from the Asteroid Terrestrial-impact Last Alert System (ATLAS) survey. Using a combination of our own data, ATLAS data, and other archival data, we confirmed the published

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Photometric Search for variable stars in the field of two Northern open clusters, DOLIDGE 14 and NGC 1960

, 2023
The aim of present work is extract and analyses the light curves of the stars in the field of two clusters, NGC 1960 and DOLIDZE 14. The photometric calibration is performed by comprehensive method of secondary standard transformation and differential ...

The Long-term Photometric Behavior of 39 Semiregular Variable Stars

The Astronomical Journal
Photometric measurements of the light and color variations of 39 semiregular variable stars over a 30 yr time interval have been used to explore the systematics of these variations.

Metastasis on pause: How dormant tumor cells stay hidden within the tumor microenvironment and evade immune surveillance

Molecular Oncology, EarlyView.
Dormant cancer cells can hide in distant organs for years, evading treatment and the immune system. This review highlights how signals from the surrounding tissue and immune environment keep these cells inactive or trigger their reawakening. Understanding these mechanisms may help develop therapies to eliminate or control dormant cells and prevent ...

StarCLR: Contrastive Learning Representation for Astronomical Light Curves

The Astrophysical Journal
With the rapid development of time-domain surveys, the availability of large-scale light-curve data offers new opportunities for studying stellar evolution and variable-star classification, while simultaneously posing challenges for feature extraction ...
