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 ...

Diagnostic Performance of Comprehensive Point‐of‐Care Ultrasound for Pediatric Tuberculosis in Spain: A Prospective Observational Study

Journal of Clinical Ultrasound, EarlyView.
In children with presumptive tuberculosis, comprehensive point‐of‐care (cPOCUS) identified key thoracic abnormalities with high specificity and excellent inter‐reader reliability. Although diagnostic sensitivity was modest and examinations often incomplete, cPOCUS shows promise as a complementary, radiation‐free imaging tool.

Home telemonitoring in high‐risk pregnancies: A Finnish retrospective cohort study

Acta Obstetricia et Gynecologica Scandinavica, EarlyView.
This retrospective study suggests that home telemonitoring may provide an acceptable approach for managing selected high‐risk pregnancies. Safe and effective implementation requires careful patient selection and adherence to evidence‐based clinical protocols.

Search for Classical Cepheids in Galactic Open Clusters and Calibration of the Period–Wesenheit–Metallicity Relation in the Gaia Bands

The Astronomical Journal
It is beneficial to calibrate the period–Wesenheit–metallicity relation (PWZR) of Delta Cephei stars (DCEPs), i.e., classical Cepheids, using accurate parallaxes of associated open clusters (OCs) from Gaia data release 3 (DR3).

The luminosity scale of Cepheid variable stars - A revison

The Astrophysical Journal, 1984
The period-luminosity-color relation for classical Cepheids is discussed in terms of a recent redeterminations of the distance moduli of open clusters with Cepheid members. The distance moduli of eight clusters with well established Cepheid members were determined from Stromgren four-color and Hp photometry of the B stars.

HIV drug resistance and treatment success in the Republic of Congo: Implications for optimized treatment

HIV Medicine, EarlyView.
Abstract Objectives Increasing rates of HIV‐1 drug resistance (HIVDR) threaten the effectiveness of antiretroviral therapy (ART) programmes in sub‐Saharan Africa, particularly among children, adolescents and young adults, who face limited treatment options.

Mass of Cepheid V350 Sgr Incorporating Interferometry and the Companion Mass

The Astrophysical Journal
The system V350 Sgr has a classical Cepheid for the primary. Interferometry is presented for the system, and the full orbit is determined. The mass of the companion has been determined from an International Ultraviolet Explorer spectrum and comparison ...

Zwicky Transient Facility and Globular Clusters: The Period–Luminosity and Period–Wesenheit Relations for Anomalous Cepheids Supplemented with Large Magellanic Cloud Sample

The Astronomical Journal, 2022
We present the first gri -band period–luminosity (PL) and period–Wesenheit (PW) relations for the fundamental mode anomalous Cepheids. These PL and PW relations were derived from a combined sample of five anomalous Cepheids in globular cluster M92 and ...

Real‐world progression‐free survival and overall survival in patients with HR+/HER2− advanced breast cancer treated in first‐line with ribociclib, endocrine monotherapy or chemotherapy: Results from the observational RIBANNA study

International Journal of Cancer, Volume 159, Issue 1, Page 210-223, 1 July 2026.
What's New? The CDK4/6 inhibitor ribociclib in combination with an endocrine‐based therapy has demonstrated significant progression‐free and overall survival benefits in patients with advanced/metastatic HR+/HER2‐ breast cancer in the pivotal MONALEESA trials.

New variable and multiple stars in the lower part of the Cepheid instability strip [PDF]

, 2005
We obtained high-resolution spectra for 33 A-type stars during 4 consecutive nights. All our targets are Hipparcos programme stars located in the lower part of the Cepheid instability strip which show hints for variability in radial velocity of a yet ...
