The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

The elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

Utilizing the polymeric platform of polypept(o)ides, this thesis describes synthesis and investigation of novel triblock copolymers to obtain carrier systems with multiple compartments for efficient siRNA delivery. Although the individual microstructure of nanoparticles differs depending on the polymeric…

Het ondersteunen van onderwijsprofessionals in hun doorlopende professionele ontwikkeling zien wij als een belangrijke taak. Voor het leveren van kwalitatief goed onderwijs zijn didactische vaardigheden net zo essentieel als vakkennis. Om dit te ondersteunen bieden wij een breed scala aan trainings-…

Whilst government’s ability to design ‘context-specific’ regional innovation policy is generally assumed to depend on the region’s decision-making power, the aim of this study is to investigate how regional government matters. In order to open up the black box of policy design, the study develops a…

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

Dark matter is one of the biggest mysteries of the Universe. Its properties cannot be explained with the known laws of physics and elementary particles.

Over the last three decades, the discovery of exoplanets has revealed the boundless variety of worlds beyond our own Solar System⁠. Majority of planetary systems contain short-period planets that are larger than Earth but smaller than Neptune⁠.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

The complexity of an intelligence problem determines to a great extent the certainty that can be provided by intelligence and security services.

In design optimization problems, engineers typically handcraft design representations based on personal expertise, which leaves a fingerprint of the user experience in the optimization data. Thus, learning this notion of experience as transferrable design features has potential to improve the performance…

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

This thesis addresses the problem of designing performance and energy efficient embedded streaming systems, that is, systems which process a stream of input data coming from the environment and generate a stream of output data going into the environment.

LCA has become an important method to study environmental impacts of human activities. Still, there are several methodological issues in LCA that can adversely affect the results reliability.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Bacterial chemosensory arrays are protein assemblies that are the key structural and functional component for motile bacteria to sense their internal or environmental chemical signals.

Breeding for resistance becomes more and more important because we want to reduce the use of pesticides. A fast and cheap alternative can be to make use of morphological or chemical markers.

Possible improvements for the assessment of abiotic depletion in LCA.

The PID-directed shift in PIN polarity has been broadly accepted as one of the essential mechanisms for the regulation of auxin transport polarity.

Forgotten Lineages explores the paths through which generations of formally enslaved and their descendants gradually forgot their past of enslavement under Dutch and British imperial rule and became local subjects in Sri Lanka and South Africa. It explores why and how forgetting rather than memory became…

Een internationaal team van astronomen, onder wie drie Leidse sterrenkundigen, hebben een sterrenstelsel ontdekt op een recordafstand van 13,4 miljard lichtjaar. Het stelsel, dat in de richting van het sterrenbeeld Grote Beer staat, is uitzonderlijk helder, waardoor het mogelijk was het op deze recordafstand…
