Machine learning regression on hyperspectral data to estimate multiple water parameters

open access: yes, 2018
In this paper, we present a regression framework involving several machine learning models to estimate water parameters based on hyperspectral data. Measurements from a multi-sensor field campaign, conducted on the River Elbe, Germany, represent the ...

The first 25 years of satellite carbonate sedimentology: What have we learned?

open access: yesThe Depositional Record, EarlyView.
Observations of the suspension and transport of carbonate sediments from reefs, banks and shallow shelves have been made by satellite instruments for ca 25 years. With an increasing number of instruments in space, providing advanced observational capabilities, remarkable insights have been gained concerning carbonate sedimentological processes. Details

Most young leaves pale in comparison to mature leaves: delayed greening is neither binary nor tropical

open access: yesEcography, EarlyView.
Delayed greening, the phenomenon in which expanding leaves appear red, blue or pale green due to low chlorophyll content, has long intrigued ecologists. However, little is known about what type of species are most likely to delay greening or which environmental conditions are associated with delayed greening.

The time of acquisition of multispectral predictors matters: the role of seasonality in bird species distribution models

open access: yesEcography, EarlyView.
Species distribution models (SDMs) analyse the relationships between species occurrences and environmental predictors. Their efficacy largely depends on the selection of ecologically relevant predictors, with remote sensing (RS) data being one of the most commonly used sources. The usability of multispectral predictors is influenced by temporal changes

Sunlight‐Driven, Catalyst‐Free Synthesis of Cyclobutanes by [2+2] Cycloaddition of Fluorinated Heterochalconoids in Solution

open access: yesEuropean Journal of Organic Chemistry, Accepted Article.
A cyclobutane ring constitutes an interesting scaffold for the development of new materials and drugs. In this work we describe the [2+2] cycloaddition of chalconoid precursors bearing fluorinated and heterocyclic moieties to produce cyclobutane derivatives in solution.
