Velocity Spectrum Imaging Using Velocity Encoding Preparation Pulses

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose The goal of this article is to introduce a technique to measure the velocity distribution of water inside each voxel of an MR image. The method is based on the use of motion sensitizing gradients with changing first moment to encode velocity. As such, it is completely non‐invasive and requires no contrast injections.

Classification of Salivary Gland Tumors on Ultrasound Using Artificial Intelligence: A Systematic Review and Meta‐Analysis

open access: yesOtolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Accurate classification of salivary gland tumors is critical to guiding appropriate management. This study evaluates the diagnostic performance of artificial intelligence models in classifying salivary gland tumors on ultrasound. Data Sources A comprehensive search of CINAHL, PubMed, and Scopus was conducted through January 28, 2025.

Thermodynamic and microphysical properties of summertime marine fog observed from Sable Island

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
Atmospheric profiling and near‐surface fog and visibility measurements revealed synoptic‐scale forcing as the dominant factor in fog formation over Sable Island, with deep fog layers under low‐pressure systems and shallow fog layers under high‐pressure systems.

A Reproducible Workflow for Macrophage Membrane Isolation and Nanocore Selection Toward Bioinspired Nanoparticles Targeting Immunologically Cold Tumors

open access: yesSmall Methods, EarlyView.
A reproducible workflow is established for isolating macrophage membranes to enable the efficient preparation and characterization of membrane‐coated nanoparticles. By optimizing M2‐like nanovesicle stability and nanocore compatibility, this procedure advances the engineering of macrophage membrane‐coated nanoparticles with improved tumor targeting ...

High-resolution Simulations of the Interaction between the Nova/Supernova Ejecta and the Accretion Disk

open access: yesThe Astrophysical Journal
Many nova and Type Ia supernova (SN Ia) explosion scenarios involve accretion disks. However, direct numerical simulations of these explosive phenomena have barely addressed the question of the impact of ejecta−disk collision on the midterm evolution of ...

Multiwavelength studies of classical novae

open access: yes, 2018
Classical novae are transient astronomical events resulting from an eruption on the surface of an accreting white dwarf in interacting binary stars, namely cataclysmic variables. These eruptions and their progenitors are ideal astronomical events/objects to study a variety of interesting topics, such as mass-transfer mechanisms, binary evolution, and ...
