Characterization of chromospheric activity based on Sun‐as‐a‐star spectral and disk‐resolved activity indices

Astronomische Nachrichten, Volume 343, Issue 5, June 2022., 2022
Abstract The strong chromospheric absorption lines Ca ii H & K are tightly connected to stellar surface magnetic fields. Only for the Sun, spectral activity indices can be related to evolving magnetic features on the solar disk. The Solar Disk‐Integrated (SDI) telescope feeds the Potsdam Echelle Polarimetric and Spectroscopic Instrument (PEPSI) of the ...

Pachyrhynchus Weevils Use 3D Photonic Crystals with Varying Degrees of Order to Create Diverse and Brilliant Displays

Small, Volume 18, Issue 20, May 19, 2022., 2022
3D photonic materials of varying order form the basis of the beautiful displays of many insects. This study characterises the ultrastructures and optical properties of the elytral scales found in a wide array of different Easter Egg weevils. The various mechanisms with which the species changes its colorful appearance are highlighted and linked to the ...

Local limit theorems for subgraph counts

Journal of the London Mathematical Society, Volume 105, Issue 2, Page 950-1011, March 2022., 2022
Abstract We introduce a general framework for studying anticoncentration and local limit theorems for random variables, including graph statistics. Our methods involve an interplay between Fourier analysis, decoupling, hypercontractivity of Boolean functions, and transference between ‘fixed‐size’ and ‘independent’ models.

SARS‐CoV‐2 infection and venous thromboembolism after surgery: an international prospective cohort study

Anaesthesia, Volume 77, Issue 1, Page 28-39, January 2022., 2022
Summary SARS‐CoV‐2 has been associated with an increased rate of venous thromboembolism in critically ill patients. Since surgical patients are already at higher risk of venous thromboembolism than general populations, this study aimed to determine if patients with peri‐operative or prior SARS‐CoV‐2 were at further increased risk of venous ...

Fast Retrieval of Cloud Optical Depth From Polarimetry and Multi‐Spectral Imagery That Accounts for Cloud Heterogeneity Using 3D Radiative Transfer

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 3, 16 February 2026.
Abstract We present a method for retrieving cloud optical depth that applies 3D radiative transfer to utilize the combination of polarimetry and multi‐spectral imagery that is newly available from satellite missions such as the Plankton, Aerosol, Cloud, Ocean, Ecosystem (PACE) Mission. Due to the approximate spectral invariance of scattering by clouds,

Feeding Mystus gulio Fry With Different Dietary Inclusion of Coccomyxa Sp.: Changes in Nutritional Profile, Pigments and Digestive Enzyme Activities

Aquaculture, Fish and Fisheries, Volume 5, Issue 4, August 2025.
ABSTRACT The aim of this study was to investigate the effects of Coccomyxa sp. on the survival, nutritional profile, pigments and digestive enzyme activities of Mystus gulio. A 75‐day feeding trial was performed during which the fish fry were fed with microalgae as a partial replacement for other nutritional components.

Understanding the Application of Plant Extracts in Wound Healing of Fish: A Comprehensive Review

Aquaculture, Fish and Fisheries, Volume 5, Issue 2, April 2025.
Abstract This review explores the latest developments in the use of plant extracts to promote fish wound healing. Healing from wounds is an essential part of maintaining fish health, especially in aquaculture where injuries can result in large losses. The potential therapeutic benefits of plant extracts, such as their antimicrobial, anti‐inflammatory ...

Essentially tight bounds for rainbow cycles in proper edge‐colourings

Proceedings of the London Mathematical Society, Volume 130, Issue 4, April 2025.
Abstract An edge‐coloured graph is said to be rainbow if no colour appears more than once. Extremal problems involving rainbow objects have been a focus of much research over the last decade as they capture the essence of a number of interesting problems in a variety of areas.

Climate Futures for Lizards and Snakes in Western North America May Result in New Species Management Issues

Ecology and Evolution, Volume 14, Issue 10, October 2024.
We assessed changes in fundamental climate‐niche space for lizard and snake species in western North America under modeled climate scenarios to inform natural resource managers of possible shifts in species distributions. Overall, reptile climate‐niche space was projected to move northward in the future. Sixty‐eight percent of species were projected to
