Modeling the Radial Distribution of Pulsars in the Galaxy

open access: yesThe Astrophysical Journal Letters
The Parkes 20 cm multibeam pulsar surveys have discovered nearly half of the known pulsars and revealed many distant pulsars with high dispersion measures.

Characterization of Fatty Acid Profiles and Nutritional Quality Indices in Commercial Spreadable Processed Cheeses: Comparative Analysis and Health Implications

open access: yesFood Safety and Health, EarlyView.
Natural processed cheeses showed a more favorable nutritional profile, including higher unsaturated fatty acids and better functional performance. A balanced fatty acid composition was identified as a key factor influencing meltability, oil separation, and overall quality of processed cheeses.

Marcasite at the Permian‐Triassic Transition

open access: yesGeophysical Monograph Series, Page 377-399., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Radial Wave in the Galactic Disk: New Clues to Discriminate Different Perturbations

open access: yesThe Astrophysical Journal
Decoding the key dynamical processes that shape the Galactic disk structure is crucial for reconstructing the Milky Way’s evolution history. The second Gaia data release unveils a novel wave pattern in the L _Z −〈 V _R 〉 space, but its formation ...

Food Contamination and Safety in Nigeria: A Systematic Synthesis of Heavy Metals, Microbial Pathogens, and Health Risk Metrics

open access: yesFood Safety and Health, EarlyView.
This is an infographic driver of food contaminants and health effects. ABSTRACT Food safety remains a critical challenge in Nigeria due to rapid urbanization and weak regulatory enforcement. This systematic review synthesizes empirical evidence from 2015 to 2025 to characterize food contaminant profiles and associated human health risks in Nigeria ...

Early Coformation of the Milky Way’s Thin and Thick Disks at Redshift z > 2

open access: yesThe Astrophysical Journal
The Milky Way serves as a template for understanding the formation and evolution of late-type massive disk galaxies since we can obtain detailed chemical and kinematic information for large samples of individual stars. However, the early formation of the

The Milky Way and its gas: Cold fountains and accretion

open access: yesEPJ Web of Conferences, 2012
The Milky Way is acquiring gas from infalling high-velocity clouds. The material enters a disk-halo interface that in many places is populated with HI clouds that have been ejected from the disk through processes linked to star formation. The Smith Cloud

Unveiling the roles of extracellular vesicles in hematologic malignancies: Pathogenesis, diagnostic tools, and clinical translation

open access: yesInterdisciplinary Medicine, EarlyView.
Extracellular vesicles play pivotal roles in both healthy hematopoiesis and hematologic malignancies. They not only regulate hematopoietic stem cell fitness but also drive cancer progression and drug resistance. Their clinical potential spans from serving as non‐invasive biomarkers to acting as innovative therapeutic platforms and drug delivery ...

A Radial Age Gradient in the Geometrically Thick Disk of the Milky Way

open access: yes
In the Milky Way, the thick disk can be defined using individual stellar abundances, kinematics, or age, or geometrically, as stars high above the midplane.

Mapping the Galactic Disk with the LAMOST and Gaia Red Clump Sample. VIII. Mapping the Kinematics of the Galactic Disk Using Mono-age and Mono-abundance Stellar Populations

open access: yesThe Astrophysical Journal
We present a comprehensive study of the kinematic properties of the different Galactic disk populations, as defined by the chemical abundance ratios and stellar ages, across a large disk volume (4.5 ≤ R ≤ 15.0 kpc and ∣ Z ∣ ≤ 3.0 kpc), by using the ...
