The time is now to use the tools we have to end AIDS in children

Journal of the International AIDS Society, Volume 28, Issue 11, November 2025.
Abstract Introduction Progress in reducing and eliminating vertical transmission of HIV in children has stagnated over recent years. Unfortunately, recent decisions in the global donor space are likely to lead to considerably lower funding available for HIV and other disease programmes in high‐burden low‐ and middle‐income settings.

The Cepheid distance to M96 and the Hubble constant [PDF]

Monthly Notices of the Royal Astronomical Society, 1999
ABSTRA C T HST WFPC2 observations of Cepheids in M96 (NGC 3368) are used to find a distance to that galaxy of 11:2 ^ 1:0 Mpc. This estimate is based on a calibration of the Cepheid period‐luminosity relation in the Large Magellanic Cloud, and includes a correction for the difference in metallicity between the two systems.

Rebound of Respiratory Virus Activity and Seasonality to Pre‐Pandemic Patterns

Journal of Medical Virology, Volume 97, Issue 11, November 2025.
ABSTRACT The emergence of SARS‐CoV‐2 and the implementation of non‐pharmaceutical interventions (NPIs) profoundly disrupted the transmission dynamics of respiratory viruses, altering their epidemiology and seasonality. However, comprehensive long‐term data on these shifts and their post‐pandemic implications remain limited.

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 ...

Treatment variations in localised prostate cancer in Australia and New Zealand: a registry study

BJU International, Volume 136, Issue S2, Page S62-S69, October 2025.
Objective To describe the patterns of care and factors associated with treatment uptake of localised prostate cancer, using the bi‐national Prostate Cancer Outcomes Registry–Australia and New Zealand (PCOR‐ANZ) database. Methods Data for 36 504 patients, diagnosed between 2015 and 2018, from New Zealand and seven Australian jurisdictions were evaluated.

A Novel q-PED Method: Precise Physical Properties of a Merger-origin Binary Cepheid OGLE-LMC-CEP-1347

The Astrophysical Journal Letters
Recently, a double-lined binary classical Cepheid, OGLE-LMC-CEP-1347, was discovered with the orbital period ( P _orb  = 59 days), 5 times shorter than that of any binary Cepheid known before.

PULSATIONAL AND ORBITAL PERIODS OF SMALL-AMPLITUDE CEPHEID SU CAS

Odessa Astronomical Publications, 2007
New seven high-resolutional spectra of small-amplitude Cepheid SU Cas have been obtained to determine its atmosphere parameters (Teff=6384 K; log g=2.4; Vt=3.3 km s-1) and to measure its radial velocities.

‘Why Didn't I Get That Choice?’: A Qualitative Exploration of How Cervical Screening Choices Are Understood and Experienced by Screen‐Eligible People in Australia, Two Years After Self‐Collection Became an Option for All

Health Expectations, Volume 28, Issue 4, August 2025.
ABSTRACT Background Australia's human papillomavirus (HPV)‐based National Cervical Screening Program guidelines state that anyone eligible for screening should be offered a choice of using self‐collection or clinician collection for initial screening. Aim To explore the awareness and experiences of women and people with a cervix who have been screened ...

On the Age Distribution of Classical Cepheids in the Galaxy

Astronomische Nachrichten, Volume 346, Issue 5, June 2025.
ABSTRACT We revisit the problem of the positive correlation between age and Galactocentric distance seen in Galactic Classical Cepheids, which at first sight may seem counter‐intuitive in the context of inside‐out galaxy formation. To explain it, we use the Besançon Galaxy Model and a simulation of star particles in the Galactic disc coupled with ...
