All Puffed Up: Exploring Ultra-diffuse Galaxy Origins Through Galaxy Interactions
The Astronomical JournalWe present new follow-up observations of two ultra-diffuse galaxies (UDGs) selected for their distorted morphologies and tidal features, suggestive of tidal influence.

Advanced Science, EarlyView.A real‐time, non‐contact photoplethysmography (PPG) system based on InAs colloidal quantum dots (CQDs) synthesized via a seedless injection synthesis is demonstrated. The measured oxygen saturation shows considerable agreement with commercial PPG devices.

The Subtle Effects of Mergers on Star Formation in Nearby Galaxies
The Astrophysical Journal, 2023 Interactions and mergers play an important role in regulating the physical properties of galaxies, such as their morphology, gas content, and star formation rate (SFR).

Effects of galaxy--satellite interactions on bar formation
, 2017 Aims. We aim to show how encounters with low-mass satellite galaxies may alter the bar formation in a Milky Way-like disc galaxy. Methods. We use high-resolution N-body simulations of a disc galaxy prone to mild bar instability.

Interacting galaxies and mergers
Nature Astronomy, 2019 Two landmark papers in the 1970s contributed strongly to establishing the importance of galaxy interactions and mergers in the formation and evolution of galaxies, using only gravity, and the ensuing dynamical friction.

The dilution peak, metallicity evolution, and dating of galaxy interactions and mergers [PDF]
, 2010 Strong inflows of gas from the outer disk to the inner kiloparsecs are induced during the interaction of disk galaxies. This inflow of relatively low-metallicity gas dilutes the metallicity of the circumnuclear gas.

The Geography of Success: A Spatial Analysis of Export Intensity in the Italian Wine Industry
Agribusiness, EarlyView.ABSTRACT This paper investigates the paradox of how Italy's fragmented, SME‐dominated wine industry achieves global export success. Moving beyond purely firm‐centric explanations, we test whether export intensity is spatially dependent, clustering geographically in regional ecosystems.

Tracing the Formation History of Intrahalo Light with Horizon Run 5
The Astrophysical JournalWe investigate the formation history of intrahalo light (IHL) using the high-resolution (∼1 kpc), large-scale (∼1 Gpc) cosmological hydrodynamical simulation Horizon Run 5 (HR5).

Global environmental effects versus galaxy interactions [PDF]
, 2009 We explore properties of close galaxy pairs and merging systems selected from the Sloan Digital Sky Survey Data Release 4 in different environments with the aim to assess the relative importance of the role of interactions over global environmental ...

Humanized immune system animal models and their recent applications
Animal Models and Experimental Medicine, EarlyView.In this review, we provide an updated and comprehensive overview of the current state of humanized immune system animal model research. We discuss the variety of techniques used to produce humanized mice with their respective strengths and weaknesses, and evaluate the advantages and limitations of these models, including issues with incomplete immune ...
