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.

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.

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

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.

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

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…

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

The energy system is at the heart of two of the greatest challenges of the 21st century: decreasing CO2 emissions to meet the ambitions of the Paris agreement while fulfilling the growing energy demand associated with the economic aspirations of a growing world population.

Wanneer een fysisch systeem symmetrieën bezit gaan deze vaak gepaard met een representatie van de symmetriegroep op een Hilbertruimte. Groepsrepresentaties op Hilbertruimten zijn intensief onderzocht.

In this thesis, topics relating to the optimization of high-throughput pipelines used for imaging are discussed. In particular, different levels of implementation, i.e., conceptual, software, and hardware, are discussed and the thesis outlines how advances on each level need to be made to make gains…

An algorithm is discussed to compute the exponential representation of principal units in a finite extension field F of the p-adic rationals.

Kohei Suzuki and his co-authors reflect on their extensive scholarly experience teaching comparative public administration across diverse countries including Canada, the Netherlands, Qatar, and the United States.

Dit onderzoek gaat over hoe automatische gebarentaalherkenningstechnologie verder ontwikkeld kan worden om statische beelden en tekstuele beschrijvingen van gebaren te analyseren.

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…

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…

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.
