Convection Theory and Related Problems in Stellar Structure, Evolution, and Pulsational Stability II. Turbulent Convection and Pulsational Stability of Stars

Frontiers in Astronomy and Space Sciences, 2021
Using our non-local and time-dependent theory of convection and a fixed set of convective parameters (C1,  C2/C1 ,   C3)= (0.70,   0.50,   3.0) calibrated against the Sun, the linear non-adiabatic oscillations for evolutionary models with masses 1–20 M ...

The Araucaria Project. The Distance to the Local Group Galaxy WLM from Cepheid Variables discovered in a Wide-Field Imaging Survey

, 2007
We have conducted an extensive wide-field imaging survey for Cepheid variables in the Local Group irregular galaxy WLM. From data obtained on 101 nights, we have discovered 60 Cepheids which include 14 of the 15 Cepheid variables previously detected by ...

Urinary biomarkers in multicentric studies: Shaping the future of bladder cancer diagnosis and follow‐up

BJUI Compass, Volume 6, Issue 12, December 2025.
Abstract Background and Objective Bladder cancer (BC), a prevalent malignancy, poses significant diagnostic and surveillance challenges due to its high recurrence rates and reliance on cystoscopy, an invasive procedure for diagnosis and monitoring.

Comparison of Sofia 2 Respiratory Syncytial Virus Fluorescent Immunoassay to Real‐Time Polymerase Chain Reaction Assay in Children Under Two Years Old Hospitalized With Acute Respiratory Illness in Amman, Jordan: A Cross‐Sectional Study

Health Science Reports, Volume 8, Issue 12, December 2025.
ABSTRACT Background and Aims Respiratory syncytial virus (RSV) is a leading cause of acute respiratory infection (ARI) in children, particularly in low‐ and middle‐income countries. Rapid diagnosis is important for management and infection control. We aimed to evaluate diagnostic accuracy of Sofia 2 RSV fluorescent immunoassay (FIA) compared to reverse‐

Chicago–Carnegie Hubble Program: A Multiwavelength Search for the Effects of Metallicity on the Cepheid Distance Scale. I. Empirical Evidence

The Astrophysical Journal
Understanding the effects of metallicity on the multiwavelength properties of Cepheids is of continuing importance for their effective use as extragalactic distance indicators and an accurate measure of the Hubble constant, H _0 .

Very accurate Distances and Radii of Open Cluster Cepheids from a Near-Infrared Surface Brightness Technique

, 1997
We have obtained the radii and distances of 16 galactic Cepheids supposed to be members in open clusters or associations using the new optical and near-infrared calibrations of the surface brightness (Barnes-Evans) method given by Fouque & Gieren (1997).

Invasive disease‐free and overall survival after (neo)adjuvant chemotherapy in postmenopausal patients with hormone receptor‐positive, HER2‐negative early breast cancer treated with upfront letrozole: Experiences from the phase IV PreFace trial

International Journal of Cancer, Volume 157, Issue 11, Page 2363-2373, 1 December 2025.
What's New? Neoadjuvant chemotherapy (NACT) can be highly effective for patients with early‐stage breast cancer. Patients with hormone receptor‐positive (HRpos), HER2‐negative (HER2neg) breast cancer, however, may benefit less from NACT. Here, the authors investigated survival outcomes with adjuvant chemotherapy or NACT in a population of ...

The Cepheid Distance Scale: A Novel Method for Obtaining Mean Magnitudes from Single-epoch Observations

The Astronomical Journal
We present a novel technique for mapping single-phase observations of Cepheids in any given band into their time-averaged values, using strong priors on the known interrelations of the multiwavelength widths of Cepheid period–luminosity (PL) relations ...
