One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

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 experiments described in this thesis employ local lentiviral knockdowns in brain areas of female zebra finches followed by behavioural assays consisting of preference and Go/Nogo tasks.

In analogy to mathematical proofs, the goal of a proof system is for a prover to convince a verifier of the correctness of a claim.

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

This research delves into the unique cultural approach of the Tenggerese people, an Indigenous community in East Java, Indonesia, regarding elderly care. It focuses on their traditional practices of bakti (‘filial piety’) and sayan (‘mutual aid’), deeply ingrained in the community's lifestyle and va…

Detecting planets during their formation stages is crucial for understanding the history and diversity of fully developed planetary systems like our own. However, observing young planets directly is challenging because they are often deeply embedded within their host protoplanetary discs, rich in gas…

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.

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

On a structural level, the properties featured by a majority of mechanical metamaterials can be ascribed to the finite number of soft internal degrees-of freedom allowing for low-energy deformations.

Less than 1 in 10 drug candidates that enter phase 1 clinical trials actually gets approved for human use.

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

The plant hormone auxin plays a central role in the growth and development of plants. Auxin acts in a concentration dependent manner and polar cell-to-cell transport of this hormone determines its distribution in the tissues of plants. This polar auxin transport is mediated by several families of auxin…

Time-series forecasting through modelling sequences of temporally dependent observations has many industrial and scientific applications. While machine learning models have been widely used to create time-series forecasting models, creating efficient and performant time-series forecasting models is…

The work described in this dissertation contributes to a better mechanistic understanding of nanoparticles in vivo. To achieve that goal, we used the zebrafish as a highly predictive pre-screening model of nanoparticles.

To gain more insight into the evolutionary development of orchid flowers and fruits, the orchid species Erycina pusilla was studied. The evolutionary origin of the median petaloid sepal, the callus on the labellum, and the stelidia was studied.

In het LLP Kenniscafé stonden geen bier en bitterballen op het menu, maar communicatievaardigheden als luisteren, conflicten oplossen en feedback geven. ‘Leer je écht te luisteren, dan word je een betere leider en leukere vriend.’

Moet de achtergrond van dit schilderij blauw blijven of terug gerestaureerd worden naar het oorspronkelijke goud? Buitenpromovendus Liselore Tissen gaat aan de slag met 3D-prints en eyetrackingsoftware om die vraag te beantwoorden. Ze ontvangt er een beurs van het NICAS van 18.000 euro voor.

Postdoc en taalwetenschapper Evelyn Bosma ontvangt voor haar proefschrift de Keetje Hodshonprijs. Voor haar onderzoek over meertaligheid van Friese kinderen won Bosma eerder al de Klokhuis Wetenschapsprijs en de Wetenschapsprijs Campus Fryslân.

The Economics and Governance specialisation of the Master in Public Administration teaches you to formulate problem-solving approaches to concrete policy issues found at the intersection between economics and public administration. This specialisation is a unique joint offering of the Department of…

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.

Sinds 2021 is de master ook in deeltijd te volgen, een parttime opleiding van 2-3 dagen per week, waarvan één vaste, verplichte dag op vrijdag.

This report investigates the different approaches in the authorization process of GMOs for commercial use in the European Union and the United States of America. Three main aspects are considered and analyzed as potential causes of differences in the authorization process of GMOs for commercial use.…

In this dissertation non-parametric Bayesian methods are used in the application of robotic vision.

How can we, together international experts, define future needs of R+D contributions for innovations in the field of risk-based management of chemicals and products in a global perspective using alternative testing strategies to minimize animal tests?

A single self-assembled semiconductor quantum dot in a high-finesse optical microcavity - the subject of this thesis - is an interesting quantum-mechanical system for future quantum applications. For instance, this system allows trapping of an extra electron and thus can serve as a spin quantum memory,…

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.

Over several decades, a variety of computational methods for drug discovery have been proposed and applied in practice. With the accumulation of data and the development of machine learning methods, computational drug design methods have gradually shifted to a new paradigm, i.e. deep learning methods…
