Interannual SAM modulation of Antarctic sea ice extent does not account for its long‐term trends, pointing to a limited role for ozone depletion
(American Geophysical Union (AGU) / Wiley, 13 October 2021)The expansion of Antarctic sea ice since 1979 in the presence of increasing greenhouse gases remains one of the most puzzling features of current climate change. Some studies have proposed that the formation of the ozone ... -
Cross-validation based adaptive sampling for Gaussian process models
(Society for Industrial and Applied Mathematics, 2021)In many real-world applications, we are interested in approximating black-box, costly functions as accurately as possible with the smallest number of function evaluations. A complex computer code is an example of such a ... -
A large-scale brain network mechanism for increased seizure propensity in Alzheimer’s disease
(Public Library of Science, 11 August 2021)People with Alzheimer’s disease (AD) are 6-10 times more likely to develop seizures than the healthy aging population. Leading hypotheses largely consider hyperexcitability of local cortical tissue as primarily responsible ... -
Climate models generally underrepresent the warming by Central Africa biomass-burning aerosols over the Southeast Atlantic
(American Association for the Advancement of Science (AAAS), 8 October 2021)The radiative budget, cloud properties, and precipitation over tropical Africa are influenced by solar absorp- tion by biomass-burning aerosols (BBA) from Central Africa. Recent field campaigns, reinforced by new remote-sensing ... -
Solar Orbiter observations of the Kelvin-Helmholtz waves in the solar wind
(European Southern Observatory (ESO) / EDP Sciences, 2021)The Kelvin-Helmholtz instability (KHI) is a nonlinear shear-driven instability that develops at the interface between shear flows in plasmas. KHI has been inferred in various astrophysical plasmas and has been observed in ...
