Interventions to Reduce Loneliness in Informal Caregivers of People With Dementia: A Systematic Review

Journal of Clinical Nursing, EarlyView.
ABSTRACT Aim To summarize the current evidence on reducing loneliness among informal caregivers of people with dementia, such as family members or friends. Design A systematic review. Methods The methodological quality was evaluated using the revised Cochrane risk‐of‐bias tool for randomized controlled trials and the revised JBI critical appraisal ...

Episodic Star Formation. I. Overview and Scatter of the Star-forming Main Sequence

The Astrophysical Journal
There is mounting evidence for episodic star formation cycles in both high- and low-redshift galaxies. This paper aims to understand the detailed physical processes behind such behaviors and investigate how such an episodic star-forming scenario can ...

Impact of the invasive diatom species Cymbella janischii on riverine microbial biofilm communities and a potential role of bacterially produced zeatin

Journal of Phycology, EarlyView.
Abstract The diatom Cymbella janischii is an invasive species in Japan, causing nuisance blooms by forming thick mats in rivers. To date, there are no documented studies on the microbiome associations in C. janischii mats or the processes that drive bloom formation.

A Close Look at Lyα Emitters with JWST/NIRCam at z ≈ 3.1

The Astrophysical Journal
We study 10 spectroscopically confirmed Ly α emitters (LAEs) at z ≈ 3.1 in the Ultra Deep Survey field, covered by the James Webb Space Telescope/NIRCam in the Public Release Imaging for Extragalactic Research program. All LAEs are detected in all NIRCam

Raman analysis of organic refractory materials after energetic processing: Evidence for amorphous carbon on TNOs and comets

Meteoritics &Planetary Science, EarlyView.
Abstract Amorphous carbon (αC) is found in various extraterrestrial particles, including those thought to originate from the outer Solar System. αC can form through two main processes involving C‐rich materials: exposure to energetic charged particles and thermal processing.

What Is the Nature of Little Red Dots and what Is Not, MIRI SMILES Edition

The Astrophysical Journal
We study 31 little red dots (LRD) detected by JADES/NIRCam and covered by the SMILES/MIRI survey, of which ∼70% are detected in the two bluest MIRI bands and 40% in redder MIRI filters.

Nanoscale space weathering features in mature lunar soil revealed by TEM and APT

Meteoritics &Planetary Science, EarlyView.
Abstract Space weathering significantly alters the optical, chemical, and structural properties of lunar regolith at micro‐ and nanoscales; yet detailed nanoscale variability within individual soils remains underexplored. Here we apply transmission electron microscopy (TEM) and atom probe tomography to four mineral grains (olivine, ilmenite, and two ...

Testing a New Star Formation History Model from Principal Component Analysis to Facilitate Spectral Synthesis Modeling

The Astrophysical Journal
The spectrum of a galaxy is a complicated convolution of many properties of the galaxy, such as the star formation history (SFH), initial mass function, and metallicity.

The 40K‐K dating system: 1. Improving data interpretation using new model calculations

Meteoritics &Planetary Science, EarlyView.
Abstract The 40K‐K cosmic‐ray exposure (CRE) dating system offers a promising method for determining exposure ages of iron meteorites by combining the radioactive cosmogenic 40K with the stable cosmogenic isotopes 39K and 41K. However, earlier applications relied on semi‐empirical production models and inconsistent analytical data sets, limiting their ...

FEAST: JWST/NIRCam View of the Resolved Stellar Populations of the Interacting Dwarf Galaxies NGC 4485 and NGC 4490

The Astrophysical Journal
We present new JWST/NIRCam observations of the interacting dwarf galaxy system NGC 4485–NGC 4490 (aka Arp 269), obtained as part of the Cycle 1 Feedback in Emerging Extragalactic Star Clusters (FEAST) program. NGC 4485 and NGC 4490 form the closest known
