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.

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.

Chemotherapy‐Induced Nausea and Vomiting in Early Breast Cancer Patients Receiving Adjuvant Chemotherapy With Fluorouracil, Epirubicin, Cyclophosphamide Followed by Docetaxel Versus an Anthracycline‐Free Regimen With Docetaxel, Cyclophosphamide—Results From a Randomized Clinical Trial

International Journal of Cancer, Volume 159, Issue 8, Page 1990-2003, 15 October 2026.
Chemotherapy‐induced nausea and vomiting (CINV) remains a significant clinical problem despite modern antiemetics. In particular, antiemetic strategies for emerging cancer therapies lack detailed evaluation. This randomized trial analyzed hourly CINV data for patients with early breast cancer who received either docetaxel plus cyclophosphamide (TC) or ...

Clinical Validation of Four Point‐of‐Care High‐Risk HPV Assays, Including Two Reduced‐Valency Assays, for Cervical Cancer Screening in Low‐Resource Settings

International Journal of Cancer, Volume 159, Issue 8, Page 2004-2014, 15 October 2026.
High‐risk human papillomavirus (hrHPV) testing improves cervical cancer screening by facilitating earlier detection and prevention. In low‐resource settings, however, cost and increased referrals limit its use. At the same time, many new and more affordable assays lack validation.

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).

Resource‐Adapted Triage Strategies for Women Testing HPV Positive With Self‐Collected Vaginal Samples in Cameroon

International Journal of Cancer, Volume 159, Issue 8, Page 1949-1961, 15 October 2026.
Although human papillomavirus (HPV) testing is recommended for cervical cancer screening in low‐ and middle‐income countries, optimal management of HPV‐positive women remains undetermined, particularly in resource‐limited settings. Here, using data from the 3T study involving women in Cameroon, the authors evaluated the ability of extended HPV ...

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 ...

Emergence of a Novel, Phenotypically Difficult‐to‐Detect Vancomycin‐Resistant Enterococcus faecium Clone (ST117/CT7799)

MicrobiologyOpen, Volume 15, Issue 5, October 2026.
A newly emerged vanB‐VREfm clone (ST117/CT7799) causes an ongoing outbreak in southeastern Austria. The cluster is highly homogenous, even for isolates sampled months apart. Resistance is easily missed via disk diffusion, gradient tests, and microdilution. VITEK 2 testing reliably detects vancomycin‐resistance.
