Foreign body ingestions in children and adolescents: A position paper of the European Society for Pediatric Gastroenterology, Hepatology, and Nutrition (ESPGHAN) endoscopy special interest group

Journal of Pediatric Gastroenterology and Nutrition, Volume 83, Issue 3, Page 539-554, September 2026.
Abstract Foreign body (FB) ingestion is a relatively frequent occurrence in the pediatric population with multiple potential sequelae. Appropriate intervention may range from urgent endoscopic retrieval to watchful waiting, with multiple variables influencing the decision.

The Evolution in Coma Molecular Composition of Comet C/2017 K2 (PanSTARRS) across the H2O Sublimation Zone: ALMA Imaging of a H2O-dominated Coma

The Planetary Science Journal
We report a survey of molecular emission from cometary volatiles using the Atacama Large Millimeter/submillimeter Array toward comet C/2017 K2 (PanSTARRS) carried out on UT 2022 September 21, 22, and 23 at a heliocentric distance ( r _H ) of 2.1 au ...

Dust–dust collisions in cometary comas: applications to comet 67P/Churyumov–Gerasimenko

Monthly Notices of the Royal Astronomical Society
ABSTRACT Silica has emerged as a crucial component within inner comet comas. This work investigates silica dust aggregates and their interactions within cometary comas. We study the probability that aggregates in the size range 1–100 µm collide with each other in the coma and analyse the outcomes of such collisions by using the ...

The composition and size distribution of the dust in the coma of Comet Hale–Bopp

Icarus, 2005
We discuss the composition and size distribution of the dust in the coma of comet Hale-Bopp. We do this by fitting simultaneously the infrared emission spectrum measured by the infrared space observatory (ISO) and the measured degree of linear polarization of scattered light at various phase angles and 12 different wavelengths.

Graded traumatic brain injury severity differentially modulates microglial and astrocytic polarization states and response to minocycline

Neuroprotection, Volume 4, Issue 3, Page 275-294, September 2026.
Schematic diagram of the experimental design and key findings of traumatic brain injury (TBI) with varying severities. Mild, moderate, and severe TBI were induced in the right motor cortex of mice using the controlled cortical impact (CCI) method, with impact depths of 0.5, 1.0, and 2.0 mm, respectively. A subset of severe TBI mice received minocycline

Impacts of Transient Critical Zone Evolution on Landslide Susceptibility and Hazard Across the Utuado Batholith, Puerto Rico

Journal of Geophysical Research: Earth Surface, Volume 131, Issue 9, September 2026.
Abstract Landscapes in humid climates often experience rapid chemical and mechanical weathering that can change groundwater fluxes, drainage pathways, and frictional strength via alterations in subsurface mineral composition and matrix porosity. These changes to hillslope critical zone structure and strength should control landslide susceptibility ...

Activity-induced Near-infrared Spectral Variability at 29P/Schwassmann–Wachmann 1, 2017–2022

The Planetary Science Journal
29P/Schwassmann–Wachmann 1 (SW1) is both the first-discovered active Centaur and the most outburst-prone comet known. The nature of SW1’s many outbursts, which regularly brighten the comet by 5 mag or more, and what processes power them has been of ...

Model Sensitivities of Biomass‐Burning Aerosol Chemical Aging, Sulfate Formation, and Cloud Droplet Activation in the Southeastern Atlantic Using CESM and E3SM

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 15, 16 August 2026.
Abstract Biomass‐burning smoke drives large uncertainty in climate projections of the Earth's radiative balance. This is due to the chemical and physical evolution of smoke and its impact on clouds and radiation. Here we focus on the southeastern Atlantic region and its inflow of African biomass‐burning smoke during August 2017.

Major factors influencing local dust radiative forcing [PDF]

, 2008
In conclusion, it is shown in this paper that surface albedo variations over desert regions can have a significant influence on the solar and net radiative forcing of desert dust.

Fungal microbiota from rain water and pathogenicity of Fusarium species isolated from atmospheric dust and rainfall dust [PDF]

, 2010
In order to determine the presence of Fusarium spp. in atmospheric dust and rainfall dust, samples were collected during September 2007, and July, August, and October 2008.
