Aim: To develop and enable application of a practical, flexible, user-friendly platform to provide the scientific community with a tool to generate land surface products and its associated uncertainties and exploit these for data-intensive science.

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

What are the behaviours of plant traits throughout various points in the growing season in a radiative transfer model framework and how well can this knowledge be integrated through data assimilation to provide priors for robust local and global vegetation products and analysis?

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

The main aim of this project is to investigate the various ways in which language categorizes possession, how these are morphosyntactically encoded across and within languages, and how this distinction should be represented in a model of the language faculty.

Building a Deep Cross-media Transfer Network to extract visual relations that relieve the problem of insufficient training data for visual tasks.

The studies described in this thesis deal with glycosidases, in particular alpha-galactosidases.

Biosynthetic gene clusters (BGCs) for natural products are widespread in microbial genomes, and they are rapidly exchanged. This research assesses the factors that control the spread of BGCs and resistance genes in nature. This includes risk assessment for the spread of engineered DNA in nature.

In this study, Tessa Dool and Thijs Bosker estimate the microplastic uptake of two odontocetes in the Mediterranean Sea and the Norteast Atlantic.

How we think about and act on the usefulness of scientific research has epistemological and political implications: what knowledge consists of, how it comes about and to what ends. In this dissertation, I situate the usefulness of scientific research in concrete places for knowledge exchange. The exchange…

PNAS publication on protein encounter complexes

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

This research will investigate which aspects of On the sublime received attention in the intellectual milieu of the seventeenth century and how the sublime found its way in the political and artistic discourse of that time. Thus I aim to shed light on the role of art in politics and society in this…

Chemists developed a new graphene-transferring method which makes use of cyclohexane. This new method leaves less impurities on graphene, is easier to handle than current methods and is widely applicable in graphene research. The publication will be on the cover of the journal ACS Central Science late…

The rapidly increasing commercial application of metallic nanoparticles within products will inevitably enhance the amount of NPs being released into soil.

The suspects of the fatal assault on Mallorca will be investigated in the Netherlands. If the Dutch Public Prosecution Service sees sufficient reason to prosecute the suspects, then a Dutch court will consider the case.

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

Over eighty percent of all Dutch requests to send asylum seekers back to the country where they should have requested asylum lead to nothing. This is shown by recent figures that Dutch broadcasting corporation NOS requested from the Ministry of Justice. That percentage applies to 2020, the year for…

The research group Politics, Culture and National Identities 1789-present investigates a wide range of national political cultures in Europe and the Americas in the 19th and 20th centuries. Instead of only analyzing high politics (the acts of governments and political parties), the research group focuses…

The Grotius Centre Working Paper Series is an occasional series through which researchers in the Grotius Centre can publish the unedited versions of manuscripts that have been accepted for publication by journals and books.
