Prediction of Astrometric and Timing Microlensing Events with Pulsars by ATNF Catalog and Gaia DR3

open access: yesThe Astrophysical Journal
Determining the mass of neutron stars is crucial for understanding their formation, evolution, and interior structure. Currently, only a few dozen neutron stars have had their masses measured, and most of them belong to binary systems. However, there are

Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research

open access: yesMass Spectrometry Reviews, EarlyView.
Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

A Systematic Search for Redback and Black Widow Candidates Based on the 4FGL-DR3 Unassociated Sources and the Zwicky Transient Facility Data

open access: yesThe Astrophysical Journal
Spider pulsars represent a unique subclass of radio millisecond pulsars in binaries, and are further categorized into black widows and redbacks according to the mass of the low-mass companion.

Nesting ecology of an ice‐associated seabird, Kittlitz's murrelet, at the northern edge of its range

open access: yesWildlife Society Bulletin, EarlyView.
We studied the Kittlitz's murrelet, an ice‐associated seabird of conservation concern, at the northern edge of its range. Over a 2‐year period, we estimated nest density and success at 2 sites, captured and telemetered nesting murrelets, and tested the use of a thermal camera to improve nest detection.

On the Contribution of Unresolved Pulsars to the Ultra-high-energy Galactic Diffuse Gamma-Ray Emission

open access: yesThe Astrophysical Journal Letters
The ultra-high-energy (UHE) Galactic diffuse gamma-ray emission holds important information on the propagation of cosmic rays in the Galaxy. However, its measurements suffer from a contamination from unresolved sources whose contribution remains unclear.

Reciprocal transport of carbon and nitrogen between plants and the hyphosphere microbiome in a temperate grassland

open access: yesNew Phytologist, EarlyView.
Overview of the experimental design and 13CO2 pulse‐labeling approach in the field. Summary Despite its relevance for plant nutrient acquisition, the role of the hyphosphere in structuring fungal–bacterial networks and mediating carbon–nitrogen (C–N) exchange under field conditions remains unclear.

Analysis of the fast optical variability and flaring activity of the transitional millisecond pulsar PSR J1023+0038

open access: yes, 2022
openSi ritiene che le millisecond pulsar (MSP) siano stelle di neutroni piuttosto vecchie ed in rapida rotazione, formate in sistemi binari e accelerate fino a periodi di rotazione dell'ordine del millisecondo durante una fase di accrescimento dalla ...

Intracerebroventricular injection of neuropeptide Y suppresses luteinizing hormone pulses in mice

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 9, September 2026.
Abstract Stress impairs reproduction, at least in part, by inhibition of Kisspeptin/Neurokinin B/Dynorphin (KNDy) cells and suppression of gonadotropin secretion. However, the mechanism for this inhibition is not clear. Neuropeptide Y (NPY) is a pleiotropic molecule that is produced in neurons throughout the brain and mediates several physiological ...

Iron‐Substituted Zn‐Al LDH‐Derived Mixed Oxides: Tailoring Structure, Composition and Redox Properties for Efficient CO2‐to‐Olefins Conversion

open access: yesChemCatChem, Volume 18, Issue 15, 14 August 2026.
LDH‐derived Zn‐Fe‐Al mixed oxides exhibited 40% CO2 conversion and 10.6% yield of light olefins. The composition and the properties of the mixed oxides strongly influenced the selectivity of products, while ZnFe2O4 and iron carbide structure promoted the conversion and the selectivity of light olefins.

Signals of the QCD Phase Transition in the Heavens [PDF]

open access: yes, 2007
The modern phase diagram of strongly interacting matter reveals a rich structure at high-densities due to phase transitions related to the chiral symmetry of quantum chromodynamics (QCD) and the phenomenon of color superconductivity.
