DOTA‐grafted Cationic Polymers Behaving as Powerful Macromolecular Resistance‐reversal Agents (MRRAs) Combating Against New Delhi Metallo‐β‐lactamase (NDM)‐producing Bacteria

Advanced Science, Volume 13, Issue 27, 13 May 2026.
Two macromolecular resistance‐reversal agents (MRRAs)—linear (MRRAL) and nanostructured (MRRAN) polymers were fabricated by integrating DOTA motifs into tunable polycationic scaffolds. MRRAs exhibit superior antibacterial potency once combined with meropenem (MEM) through (i) bacterial membrane disruption via localized cationic charge and ...

Fundamentalization of Periods for First- and Second-overtone Classical Cepheids

The Astrophysical Journal Letters
Almost half of all classical Cepheids do not pulsate in fundamental mode, and nowadays, the fundamentalization of their higher-mode periods is frequently applied to increase the sample size in astrophysical investigations and allow for comparison with ...

VLA observations of Cepheid variables

The Astronomical Journal, 1988
The 3-sigma, 5 GHz flux-density upper limits between 120 and 180 microJy have been obtained for the classical Cepheids FF Aql, Eta Aql, SU Cas, Delta Cep, and T Mon, and the Type II Cepheids CS Cas and SW Tau using the VLA. On the basis of assumptions outlined in the main text, upper limits for the ionized mass-loss rates of order 10 to the -9th to 10 ...

Paediatric and Adult Solid Tumours Exhibiting NTRK Gene Fusions in Australia, 2020–2044: A Population‐Based Statistical Modelling Study

Cancer Medicine, Volume 15, Issue 5, May 2026.
We projected 1‐year to 5‐year cancer prevalence associated with NTRK gene fusions in Australia, from 2020 to 2044, for all paediatric cancers combined (age < 18 years at diagnosis), all adult solid cancers combined, 18 cancer types/groups, and 5 cancer sub‐types relevant to current Australian government subsidies of TRK inhibitors.

Systematics in the Cepheid and TRGB Distance Scales: Metallicity Sensitivity of the Wesenheit Leavitt Law

The Astrophysical Journal
Using an updated and significantly augmented sample of Cepheid and tip of the red giant branch (TRGB) distances to 28 nearby spiral and irregular galaxies, covering a wide range of metallicities, we have searched for evidence of a correlation of the zero-

Faint (and bright) variable stars in the satellites of the Milky Way

EPJ Web of Conferences, 2017
I describe two ongoing projects related with variable stars in the satellites of the MilkyWay. In the first project, we are searching for dwarf Cepheid stars (a.k.a δ Scuti and/or SX Phe) in some of the classical dwarf spheroidal galaxies. Our goal is to

Extended Genotyping as Triage of HPV Positive Screened Women in Low‐and‐Middle Income Countries

Journal of Medical Virology, Volume 98, Issue 5, May 2026.
ABSTRACT Cervical cancer screening coverage in low‐ and middle‐income countries is low, and many screened women are lost to follow‐up. Point‐of‐care testing that allows same‐day treatment could reduce the incidence of this cancer, but same‐day triage testing is required to prevent overtreatment and minimise loss‐to‐follow‐up before treatment.

OGLE-IV Period–Luminosity Relation of the LMC: An Analysis Using Mean and Median Magnitudes

The Astronomical Journal
The Period–Luminosity (PL) relation for Cepheid variable stars in the LMC is crucial for distance measurements in astronomy. This study analyzes the impact of using the median rather than the mean of the PL relation’s slope and zero-point.

Factors Associated With Adult Incarceration Among People With Opioid Use Disorder in New South Wales, Australia

Drug and Alcohol Review, Volume 45, Issue 4, May 2026.
ABSTRACT Introduction People with opioid use disorder (OUD) are at elevated risk of incarceration. Understanding factors linked to this risk may support more targeted prevention and intervention efforts. This study used cross‐sectional survey data to examine associations with time to first incarceration and repeated incarceration among individuals with

Converging on the Cepheid Metallicity Dependence: Implications of Nonstandard Gaia Parallax Recalibration on Distance Measures

The Astrophysical Journal
By comparing Cepheid brightnesses with geometric distance measures including Gaia EDR3 parallaxes, most recent analyses conclude metal-rich Cepheids are brighter, quantified as γ ∼ −0.2 mag dex ^−1 .
