Establishment of an MRI‐Based Diagnostic Approach to Identify Critical Pulpal Inflammation Zones in a Rat Caries‐Derived Pulpitis Model

International Endodontic Journal, Volume 59, Issue 8, Page 1664-1679, August 2026.
ABSTRACT Aim To establish a magnetic resonance imaging (MRI)‐based diagnostic approach for identifying ‘critical pulpal inflammation’ zones in a rat model of caries‐derived pulpitis. Methodology Caries‐derived pulpitis was induced in the molars of Sprague–Dawley rats using the caries‐derived pulpitis model.

Postfrontal Deep Convection Over the Southern Ocean and Orographic Precipitation Enhancement Over Tasmania

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The orographic precipitation enhancement (OPE) generated within wintertime post‐frontal air masses is a prominent climate feature of Tasmania. This study investigates a passage of a cold sector of a mid‐latitude cyclone over the Southern Ocean (SO) and Western Tasmania (WTAS) observed from 2100 UTC 11 July to 0300 UTC 13 July.

Contribution of Aloft Gravitational Sorting and Lower‐Part Coalescence to Precipitation Over the Southeastern Tibetan Plateau

Geophysical Research Letters, Volume 53, Issue 14, 28 July 2026.
Abstract Observational constraints on the vertical microphysical evolution of mixed‐phase precipitation across the melting layer over the high‐altitude of southeastern Tibetan Plateau remain scarce. Using collocated two‐dimensional video disdrometer and Micro Rain Radar measurements in rainy seasons of 2022–2025, we characterize the vertical ...

Adaptive TPHD Tracking for Individuals Within a Bird Flock Using Doppler Features

Remote Sensing
Tracking multiple targets within a group is a challenging task in the radar field, especially for a bird flock. Targets in a group are usually closely spaced and exhibit similar characteristics. Additionally, the tracking radar typically employs a narrow

The Synoptic, Microphysical, and Radar Characteristics of Upper Great Lakes Snow Events

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 14, 28 July 2026.
Abstract The upper Great Lakes region is well‐known for significant snowfall during the winter months. The microphysical characteristics of the snow depend to a great degree on snow particle formation and growth processes that are linked to regime‐dependent environmental conditions.
