Stratospheric NO and NO2 profiles at sunset from analysis of high-resolution balloon-borne infrared solar absorption spectra obtained at 33 deg N and calculations with a time-dependent photochemical model [PDF]

open access: yes
Simultaneous stratospheric vertical profiles of NO and NO2 at sunset were derived from an analysis of infrared solar absorption spectra recorded from a float altitude of 33 km with an interferometer system during a balloon flight.

On the equivalence of regularization schemes

open access: yes, 2001
We illustrated via the sunset diagram that dimensional regularization 'deforms' the nonlocal contents of multi-loop diagrams with its equivalence to cut-off regularization scheme recovered only after sub-divergence were subtracted.

Classification of Fog Life‐Cycle Phases Using Ground‐Based and Satellite‐Based Observations

open access: yesQuarterly Journal of the Royal Meteorological Society, EarlyView.
In this study, the life‐cycle phases of radiation fog events—formation, maturity, and dissipation—are automatically classified at a ground station in Southwest Germany based on visibility trends and thresholds. We demonstrate that visibility detects radiation fog phases effectively, while its combination with ceilometer data can detect the life‐cycle ...

Night lights from space: potential of SDGSAT‐1 for ecological applications

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Our study emphasizes the importance of advancing ALAN monitoring from space for ecology and conservation, and it highlights the novel opportunities of SDGSAT‐1. We discuss shortcomings that need to be resolved and identify promising avenues for sound ecological impact assessments of ALAN on ecosystems using space‐borne remote sensing.

Shifting Mycobacterial Serine Hydrolase Activity Visualized Using Multi-Layer In-Gel Activity Assays

open access: yesMolecules
The ability of Mycobacterium tuberculosis to derive lipids from the host, store them intracellularly, and then break them down into energy requires a battery of serine hydrolases. Serine hydrolases are a large, diverse enzyme family with functional roles

DuckNet: an open‐source deep learning tool for waterfowl species identification in UAV imagery

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Using drones with thermal‐RGB sensors and a deep learning model (RetinaNet with ResNet‐50), we surveyed non‐breeding waterfowl across restored wetlands in the Mississippi Alluvial Valley. Our model, DuckNet, achieved high accuracy and offers an open‐source, customizable tool for automated waterfowl detection to support conservation monitoring ...
