Simulating an isolated dwarf galaxy with multichannel feedback and chemical yields from individual stars [PDF]
Monthly notices of the Royal Astronomical Society, 2018 In order to better understand the relationship between feedback and galactic chemical evolution, we have developed a new model for stellar feedback at grid resolutions of only a few parsecs in global disk simulations, using the adaptive mesh refinement ...

Roll‐To‐Roll Production of Smart Dressings for Wound Monitoring
Advanced Healthcare Materials, EarlyView.This study presents a roll‐to‐roll manufactured smart wound dressing capable of visually monitoring key wound biomarkers, including pH, humidity, and temperature. By integrating colorimetric sensors into flexible dressing substrates, the device offers real‐time, equipment‐free insights for infection detection and wound management, representing a ...

Overmerging and M/L ratios in phenomenological galaxy formation models
, 1999 We show that the discrepancy between the Tully-Fisher relation and the luminosity function predicted by most phenomenological galaxy formation models is mainly due to overmerging of galaxy haloes.

Inflow, Outflow, Yields, and Stellar Population Mixing in Chemical Evolution Models [PDF]
, 2016 Chemical evolution models are powerful tools for interpreting stellar abundance surveys and understanding galaxy evolution. However, their predictions depend heavily on the treatment of inflow, outflow, star formation efficiency (SFE), the stellar ...

Thermochromic Gires‐Tournois Resonators with Tellurium for Battery Thermal Runaway Warning
Advanced Materials, EarlyView.A thermochromic Gires‐Tournois (GT) resonator with a thin tellurium layer enables rapid, reversible, and untethered detection of battery surface temperature <80 °C. Exploiting tellurium's refractive index change driven by a thermally induced phase transition between solid and quasi‐liquid states, the GT resonator visualizes heat propagation, providing ...

Modeling the Ages and Chemical Abundances of Elliptical Galaxies
The Astrophysical JournalSpectroscopic studies of elliptical galaxies show that their stellar population ages, mean metallicity, and α enhancement traced by [Mg/Fe] all increase with galaxy stellar mass or velocity dispersion.

Chemical Evolution of Galaxies
, 1987 We review some of the present ideas on chemical evolution of irregular galaxies and disks of spiral galaxies. Based on the O abundances in stars and H II regions we present a discussion of the yield; we also discuss the effects of large scale mass flows and of cold dark matter to explain variations in the observed yield. The C, N, O observed abundances

Galaxy simulation with the evolution of grain size distribution [PDF]
Monthly notices of the Royal Astronomical Society, 2019 We compute the evolution of interstellar dust in a hydrodynamic simulation of an isolated disc galaxy. We newly implement the evolution of full grain size distribution by sampling 32 grid points on the axis of the grain radius. We solve it consistently

Advanced Materials Interfaces, EarlyView.This study examines how different laser‐patterned copper and brass surfaces, including copper coatings, affect the survival of vancomycin‐resistant Enterococcus faecium. Using microscopy and genome analysis, the results show that copper tolerance varies between strains and can increase after vancomycin exposure.
