JWST Census for the Mass–Metallicity Star Formation Relations at z = 4–10 with Self-consistent Flux Calibration and Proper Metallicity Calibrators

open access: yesThe Astrophysical Journal Supplement Series, 2023
We present the evolution of the mass–metallicity (MZ) relation at z = 4–10 derived with 135 galaxies identified in JWST/NIRSpec data taken from the three major public spectroscopy programs of ERO, GLASS, and CEERS.

Targeting Amastigote and Trypomastigote Phases: Multi‐Epitope Vaccine Strategy Against Trypanosoma cruzi

open access: yesBiotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Effective vaccines against Trypanosoma cruzi, the causative agent of Chagas disease, are urgently needed. Here, we report the design and in silico validation of a novel multiepitope vaccine construct targeting the key surface proteins ASP‐2 and gp82. Using a comprehensive immunoinformatics pipeline, we identified and selected 38 potent T‐cell (

Radial Gradients and Intrinsic Scatter in MaNGA Galaxies

open access: yesThe Astrophysical Journal Supplement Series
We derive stellar population parameters and radial gradients within 0.65 R _e for spatially resolved spectra of 2968 early-type galaxies from MaNGA, spanning stellar velocity dispersions ( σ ) of 50–340 km s ^−1 .

Rethinking Climate Change on the Role of Human Power Generation, Alternative Perspectives, Potential Solutions, and a Plea for Action

open access: yesChemie Ingenieur Technik, EarlyView.
All energy matters Let us broaden the discussion on solutions to climate change. Greenhouse gases have upset the delicate equilibrium of the Earth's energy balance. Consequently, all sources of heat affect the temperature of the Earth. Although the amount of additional heat generated by humans is a fraction of that produced by the sun, it is generated ...

Inside-out versus Upside-down: The Origin and Evolution of Metallicity Radial Gradients in FIRE Simulations of Milky Way-mass Galaxies and the Essential Role of Gas Mixing

open access: yesThe Astrophysical Journal
Within the Milky Way (MW), younger stellar populations exhibit steeper (more negative) metallicity radial gradients; the origin of this trend remains debated. The FIRE-2 cosmological simulations of MW-mass galaxies show the same trend as the MW, which in

Exploring the Relationship between Stellar Mass, Metallicity, and Star Formation Rate at z ∼ 2.3 in KBSS-MOSFIRE

open access: yesThe Astrophysical Journal
The metal enrichment of a galaxy is determined by the cycle of baryons in outflows, inflows, and star formation. The relative contribution and timescale of each process sets the relationship between stellar mass, metallicity, and the star formation rate (

Attitudes and behaviours of consumers towards plant‐based yoghurt alternatives: a cross‐cultural study

open access: yesJournal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Increased awareness of sustainable food production and vegan, vegetarian and flexitarian diets are driving the growth in dairy substitutes, particularly plant‐based yoghurts. To understand consumer perception or mind‐set and facilitate adoption of plant‐based yoghurt products, a multi‐phase study using both qualitative and ...

Two-process Model and Residual Abundance Analysis of the Milky Way Massive Satellites

open access: yesThe Astrophysical Journal
The “two-process model” is a promising technique for interpreting stellar chemical abundance data from large-scale surveys (e.g., the Sloan Digital Sky Survey IV/V and the Galactic Archeology with HERMES survey), enabling more quantitative empirical ...

Germanium‐Based Mid‐Infrared Integrated Photonics

open access: yesLaser &Photonics Reviews, EarlyView.
The mid‐infrared (mid‐IR) spectral range is a part of the electromagnetic spectrum in which most of the molecules have vibrational and rotational resonances. Photonics integration in this wavelength range have thus seen a burst of interest in the recent years, mainly driven by applications related with the detection of chemical and biological ...
