In this thesis we use Josephson and noise scanning tunneling microscopy for the study of conventional, unconventional (iron-based) and disordered superconductors. On the one hand, Josephson scanning tunneling microscopy allows us to directly visualize the superfluid density with high spatial resolut…

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

1. To what extent do metallic NPs added to soil extractions change the activity, abundance, or community composition of microbes? 2. How do the effects of metallic NPs on soil microbes differ from the effects of the ions shedding from corresponding NPs?

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

How presence, abundance and enzymatic activities of AM and EM fungi differently affect soil carbon sequestration processes?

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

All life on earth contains DNA, which is used to store biological information. Organisms compact their DNA in order for it to fit inside their cell(s).

This project, South American population history revisited: multidisciplinary perspectives on the Upper Amazon (SAPPHIRE), investigates population dynamics in western South America on the basis of traces in the geographical, genetic, archaeological, ethnological, and linguistic record.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.

The lipids in the uppermost layer of the skin, the stratum corneum (SC), play an important role in the skin barrier function. The three main SC lipid classes are ceramides (CER), cholesterol and free fatty acids.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

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

This thesis addresses questions on effectively using variational quantum circuits for machine learning tasks.

How are links between macro-invertebrate diversity and ecosystem functioning influenced by anthropogenic pressures?

Unconstrained day-to-day activities are difficult to quantify and how the corresponding movements shape the brain remain unclear. Read more

Can we distinguish the effects of pesticides from other abiotic and biotic factors that occur in the field? And how do these factors interact with pesticides?

The soil ecosystem consists of the largest reservoir of biodiversity on Earth.

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

The thesis mainly contributes to the characterization of Majorana fermions as they appear in the Condensed Matter context.

This thesis describes the role of pollution, specifically neonicotinoid insecticides, as an actor of the ongoing biodiversity decline.

Lysosomal glycosidases are acid hydrolases that fragment glycoconjugates in lysosomes.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

Spectroscopic studies on fluorescent single molecules in organic condensed matter does not only provide information about the molecule itself, but also its near environment. By suppression of phonon-induced broadening of spectral lines through cooling to low temperatures, small changes in the spectral…

Met ingang van 1 april 2018 is Erik Danen benoemd tot hoogleraar Cancer drug target discovery bij het Leiden Academic Centre for Drug Research (LACDR). Zijn vakgebied is celbiologie van kanker, waarin hij zich richt op de achterliggende mechanismen bij uitzaaiingen en resistentie voor behandelingen.

Op 18 september 2019 verdedigde Huw Llewellyn zijn proefschrift 'An Institutional Perspective on the United Nations Criminal Tribunals: Governance, Independence and Impartiality'. Het promotieonderzoek is begeleid door promotoren prof.dr. N.M. Blokker en prof.dr. L.J. van den Herik.

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

Nature uses a special class of histone proteins, histone variants, to modulate the properties of chromatin at defined genomic locations.

The research described in this thesis combines the latest insights in lysosomal function with lysosome centred cell signalling.

Anthropogenic noise has been shown to affect marine animals in various ways, this may have fitness consequences at individual and population level. This thesis aims to increase insight into the quantification of sound-induced behavioural responses that are relevant to fitness, and into factors that…
