Photometric Metallicity of Galactic RR Lyrae Stars in the Gaia DR3 Era

Galaxies
RR Lyrae stars are pulsating variables crucial for distance determination and galactic structure studies. Metallicities of fundamental-mode (RRab) RR Lyrae stars are commonly derived from photometry using empirical relations involving the Fourier ...

Inhibition of Ornithine Decarboxylase 1 Mitigates Denervation‐Induced Muscle Atrophy by Suppressing Proteolysis and Preserving Muscle Stem Cell Homeostasis

Cell Proliferation, EarlyView.
Polyamine metabolism is innervation responsive and involved in denervation‐induced muscle atrophy. Inhibition of polyamine metabolism attenuates muscle atrophy by restraining proteolysis and preserving MuSCs homeostasis. Denervation‐induced activation of FAP‐derived FGF7 drives premature MuSCs activation, while DFMO suppresses this paracrine cue to ...

Methodology for assessing the suitability of immature stages of Lepidoptera for nocturnal surveying using ultraviolet flashlights

Ecological Entomology, EarlyView.
Lepidoptera are highly sensitive to changes in their surroundings, making them excellent indicators of ecosystem health; however, surveying adult butterflies of certain species presents challenges. Nocturnal surveying of larvae and pupae using ultraviolet light (UV) is gaining popularity as a simple, inexpensive, and non‐invasive method.

Ice chemistry that can be unveiled with the JWST: SynthIceSpec, a synthetic spectrum generator to test spectral limits

Astronomy & Astrophysics
As the James Webb Space Telescope (JWST) pursues its observing journey, several thousands of icy-grain spectra are expected to be measured and analysed.

The commercialization of labour markets: Evidence from wage inequality in the Middle Ages

The Economic History Review, EarlyView.
Abstract This paper moves beyond the focus on ‘average’ wage trends in pre‐industrial economies by examining the broad diversity of pay rates and forms of remuneration across occupations and regions in medieval England. We find that whilst some workers enjoyed substantial growth in wage rates after the Black Death, there was a large group who ...

Asymptotic giant branch-stars in the GLIMPSE database

Astronomy & Astrophysics
Aims. In the preceding paper (paper I) we showed that the GLIMPSE database contains millions of asymptotic giant branch (AGB) stars. Their nature follows from two properties: the objects have the same color after correction for interstellar extinction ...

Anthropogenic and natural factors are associated with bird dawn chorus onset in subtropical East Asia

Ibis, EarlyView.
Anthropogenic factors such as artificial lighting at night (ALAN) and natural factors including temperature and moonlight can affect the dawn chorus pattern in birds. However, most studies are conducted in temperate regions. We investigated the effect of anthropogenic and natural factors on dawn chorus timing in eight species of bird across Hong Kong ...

Shedding light on the environmental efficiency of the public light service: minimising light pollution through the global Malmquist–Luenberger index

International Transactions in Operational Research, EarlyView.
Abstract The search for evidence in public management and the implementation of good management by public bodies is becoming increasingly important, and the principles of effectiveness and efficiency should be reinforced. Therefore, this paper aims to analyse the change in efficiency in the provision of public lighting services by local governments ...
