SDSS-IV MaNGA: Spatial Evolution of Gas-phase Metallicity Changes Induced by Galaxy Interactions

open access: yesThe Astrophysical Journal
Gas-phase metallicity in interacting and merging galaxies offers key insights into their star formation processes and evolutionary histories. This study investigates the spatial evolution of gas-phase metallicity (i.e., oxygen abundance, 12 + log(O/H ...

Impact of stellar population models on the estimated physical properties of galaxies

open access: yesAstronomy & Astrophysics
Context. Accurate estimates of fundamental physical properties of galaxies, such as star formation rates (SFRs) or stellar masses, are essential for testing and constraining models of galaxy formation and evolution.

Modular training resources for bioimage analysis

open access: yesJournal of Microscopy, EarlyView.
Abstract Modern microscopy enables us to measure structural and dynamical properties of many biological processes and is therefore an indispensable research tool. However, the amount and complexity of the produced imaging data is steadily increasing.

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

open access: yesJournal 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 ...

Deep Swift/UVOT Observations of GOODS-N and the Evolution of the Ultraviolet Luminosity Function at 0.2 < z < 1.2

open access: yesThe Astrophysical Journal
We present Swift Ultraviolet Optical Telescope (UVOT) observations of the deep field GOODS-N in four near-UV filters. A catalog of detected galaxies is reported, which will be used to explore galaxy evolution using UV emission.

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

open access: yesJournal 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.

Mutual Outsourcing in a Vertically Related Market With Strategic Environmental Corporate Social Responsibility

open access: yesThe Manchester School, EarlyView.
ABSTRACT This study considers mutual outsourcing firms in a vertically related market and examines their strategic adoption of environmental corporate social responsibility (ECSR) activities. We demonstrate that ECSR adoption reduces mutual outsourcing firms' profits, resulting in a prisoner's dilemma situation, but enhances welfare regardless of ...

Faint galaxy photometry and cosmology [PDF]

open access: yes, 1985
Deep galaxy catalogues have been constructed from automatic measurements of photographic plates by the COSMOS machine at the Royal Observatory Edinburgh. The plates were taken by the 1.2m UK Schmidt telescope (UKST) and 4m Anglo-Australian telescope (AAT)

Noble gases and nitrogen in material from asteroid Bennu

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract We report the elemental and isotopic abundances of all stable noble gases (helium, neon, argon, krypton, and xenon) in eight particles from asteroid Bennu returned by NASA's OSIRIS‐REx mission. We also report nitrogen abundances and isotopic ratios that were analyzed alongside neon and argon in four additional Bennu particles.
