The language of Stratified Sets is confluent and strongly normalising [PDF]

open access: yes, 2018
We study the properties of the language of Stratified Sets (first-order logic with $\in$ and a stratification condition) as used in TST, TZT, and (with stratifiability instead of stratification) in Quine's NF.

Investigating Hypoxic and Euxinic Area Changes Based on Various Datasets From the Baltic Sea

open access: yesFrontiers in Marine Science, 2022
The Baltic Sea is a coastal sea with the world’s largest anthropogenically induced hypoxic bottom area. Although hypoxia has periodically occurred during the sea’s 8,000-year history, the rapid rise in the population and intensified agriculture after ...

A more realistic representation of overshoot at the base of the solar convective envelope as seen by helioseismology [PDF]

open access: yes, 2011
The stratification near the base of the Sun's convective envelope is governed by processes of convective overshooting and element diffusion, and the region is widely believed to play a key role in the solar dynamo. The stratification in that region gives

Effect of wind on summer chlorophyll-a variability in the Yellow Sea

open access: yesFrontiers in Marine Science, 2023
Winds potentially affect primary production in shelf seas during the stratified season by enhancing upwelling and mixing. However, the exact extent and modalities of this effect in the Yellow Sea remain unclear.

Seasonal Stratification and Biogeochemical Turnover in the Freshwater Reach of a Partially Mixed Dredged Estuary

open access: yesFrontiers in Marine Science, 2021
The Elbe estuary is a substantially engineered tidal water body that receives high loads of organic matter from the eutrophied Elbe river. The organic matter entering the estuary at the tidal weir is dominated by diatom populations that collapse in the ...

Migration and Stratification [PDF]

open access: yesSSRN Electronic Journal, 2011
Migration and stratification are increasingly intertwined. One day soon it will be impossible to understand one without the other. Both focus on life chances. Stratification is about differential life chances - who gets what and why - and migration is about improving life chances - getting more of the good things of life.
