Catalog of Integrated-light Star Cluster Light Curves in TESS

The Astronomical Journal, 2023
We present the first integrated-light, TESS-based light curves for star clusters in the Milky Way, Small Magellanic Cloud, and Large Magellanic Cloud. We explore the information encoded in these light curves, with particular emphasis on variability.

Long‐term outcomes following a 5‐year recurrence‐free interval in non‐muscle‐invasive bladder cancer

BJU International, Volume 138, Issue 1, Page 125-132, July 2026.
Objective To describe the recurrence and progression trends of non‐muscle‐invasive bladder cancer (NMIBC) during a 14‐year period in Denmark between 2009 and 2022. Furthermore, to evaluate the risk of late recurrence with or without progression in patients who initially experience a 5‐year recurrence‐free interval (RFI).

Eros variable stars: A catalog of Cepheids in the Magellanic Clouds

, 1999
We present a catalog containing 290 LMC and 590 SMC Cepheids which have been obtained using the two 4k $\times$ 8k CCD cameras of the EROS~2 microlensing survey. The Cepheids were selected from 1,134,000 and 504,000 stars in the central regions of the LMC and SMC respectively, that were monitored over 150 nights between October 1996 and February 1997 ...

The Dependence of the Extinction Coefficient on Reddening for Galactic Cepheids

The Astrophysical Journal
Cepheids are fundamental distance indicators, playing a crucial role not only in the cosmic distance ladder but also in mapping the structure, kinematics, and extinction properties of the Milky Way.

Variable Stars in M13. III. The Cepheid Variables and their Relation to Evolutionary Changes in Metal-poor BL Her Stars

Acta Astronomica, 2019
New CCD photometry has been combined with published and unpublished earlier observations to study the three Cepheid variables in M13: V1, V2 and V6. The light curve characteristics in $B$, $V$ and $I_{\rm C}$ have been determined and the periods updated.

Bayesian Evaluation of Treatment Effect of Avelumab Plus Axitinib for Advanced Renal Cell Carcinoma

Cancer Medicine, Volume 15, Issue 6, June 2026.
ABSTRACT Background Despite not achieving statistical significance, the JAVELIN Renal 101 trial indicated a potentially clinically relevant effect size (hazard ratio [HR], 0.88; 95% confidence interval, 0.75 to 1.04) on overall survival (OS) favoring avelumab plus axitinib over sunitinib for advanced renal cell carcinoma (aRCC).

Variable stars towards the bulge of M31: the AGAPE catalogue

, 2004
We present the AGAPE astrometric and photometric catalogue of 1579 variable stars in a 14'x10' field centred on M31. This work is the first survey devoted to variable stars in the bulge of M31.

Female Genital Tuberculosis, Ghana: A Case Report

Clinical Case Reports, Volume 14, Issue 6, June 2026.
ABSTRACT Female genital tuberculosis is an underdiagnosed cause of infertility and amenorrhea in tuberculosis‐endemic regions. Hysteroscopy combined with histopathology can confirm the diagnosis even when molecular testing is negative. Clinicians should maintain a high index of suspicion and pursue multimodal diagnostic evaluation in women with ...

V659 Cen: System Members Updated

The Astronomical Journal
V659 Cen is a classical Cepheid which is part of a multiple system. Previous observations have shown that a hot companion dominates an ultraviolet spectrum and a cooler main-sequence star dominates an XMM-Newton spectrum. The Hubble Space Telescope Space
