Meteorological impacts of the total solar eclipse of 21 August 2017 [PDF]

open access: yes, 2018
A solar eclipse presents many opportunities for examining the impact of the reduction in solar radiation upon meteorological conditions, particularly so as accurate predictions of the circumstances and extent of the eclipse well before the event enable ...

Assessing the growth kinetics and stoichiometry of Escherichia coli at the single‐cell level

open access: yesEngineering in Life Sciences, Volume 23, Issue 1, January 2023., 2023
Abstract Microfluidic cultivation and single‐cell analysis are inherent parts of modern microbial biotechnology and microbiology. However, implementing biochemical engineering principles based on the kinetics and stoichiometry of growth in microscopic spaces remained unattained.

The Standardisation and Sequencing of Solar Eclipse Images for the Eclipse Megamovie Project [PDF]

open access: yesSolar Physics, Volume 290, Issue 8, pp.2381-2391, 08/2015, 2015
We present a new tool, the Solar Eclipse Image Standardisation and Sequencing (SEISS), developed to process multi-source total solar eclipse images by adjusting them to the same standard of size, resolution, and orientation. Furthermore, by analysing the eclipse images we can determine the relative time between the observations and order them to create

Coronal Magnetic Field Topology from Total Solar Eclipse Observations [PDF]

open access: yesAstrophysical Journal, 2020
Measuring the global magnetic field of the solar corona remains exceptionally challenging. The fine-scale density structures observed in white-light images taken during total solar eclipses are currently the best proxies for inferring the magnetic field ...

New eclipsing binaries with mercury-manganese stars [PDF]

open access: yes, 2021
Eclipsing binary stars are rare and extremely valuable astrophysical laboratories that make possible precise determination of fundamental stellar parameters. Investigation of early-type chemically peculiar stars in eclipsing binaries provides important information for understanding the origin and evolutionary context of their anomalous surface ...
