Published in 2017 at "Geophysical Research Letters"

DOI: 10.1002/2017gl074678

Abstract: Radar echoes from the daytime equatorial ionospheric F1 region, popularly known as “150 km echoes,” have challenged ionospheric plasma physicists for several decades. Recent theoretical simulations showed that enhanced photoelectron fluxes can amplify the amplitude of… read more here.

Published in 2022 at "Drug testing and analysis"

DOI: 10.1002/dta.3335

Abstract: BACKGROUND Greater nicotine delivery is associated with higher nicotine concentrations in Electronic Nicotine Delivery System (ENDS) liquids. However, there is a current debate as to whether this leads to increased dependence and mitigates ENDS public… read more here.

Published in 2023 at "Ecology and Evolution"

DOI: 10.1002/ece3.10044

Abstract: Abstract The benefit of pollinators to crop production is normally calculated using “pollinator dependence ratios,” which reflect the proportion of yield lost (here reported as a value between 0 and 1) in the absence of… read more here.

Published in 2020 at "Ecology"

DOI: 10.1002/ecy.2997

Abstract: Why some species become invasive while others do not remains an elusive question. It has been proposed that invasive species should depend less on mutualisms, because their spread would then be less constrained by the… read more here.

Published in 2023 at "Ecology"

DOI: 10.1002/ecy.4021

Abstract: Applications of ecological theory to natural communities often assume that competitive, negative density-dependent processes are the only type of interaction important for diversity maintenance. Recent advances suggest that positive interactions within trophic levels (e.g. plant-plant)… read more here.

Published in 2020 at "Environmetrics"

DOI: 10.1002/env.2605

Abstract: The assessment of long‐term trends in environmental extremes is a challenging and important subject in the current discussion on global climate change. We propose a new approach for evaluating temporal trends and spatial homogeneity in… read more here.

Published in 2018 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.26812

Abstract: Water exchange exists between different neuronal compartments of brain tissue but is often ignored in most diffusion models. The goal of the current study was to demonstrate the dependence of diffusion measurements on echo time… read more here.

Published in 2022 at "Magnetic Resonance in Medicine"

DOI: 10.1002/mrm.29428

Abstract: The effective transverse relaxation rate ( R2*$$ {\mathrm{R}}_2^{\ast } $$ ) is influenced by biological features that make it a useful means of probing brain microstructure. However, confounding factors such as dependence on flip angle… read more here.
