In this Ph.D. thesis, we characterized two novel upstream regulators of JUB1, HB40, and HB22, in Arabidopsis thaliana. In Chapter 2, we described functions of HB40 in modulating growth and development via the regulation of JUB1 and GA inactivation genes GA2OXs.

This thesis describes the development of improved formulations and alternative delivery strategies for polio vaccination.

Bacterial biocatalysis constitutes a sustainable alternative for high-value chemicals production by enabling the utilization of renewable feedstocks.

Retorica is overal. In de Tweede Kamer, in de rechtbank, en in de collegezaal; maar ook op de markt, op Twitter, en op Facebook. Mensen proberen elkaar steeds weer te overtuigen met argumenten, te verleiden met emoties, en te imponeren met een gunstige zelfpresentatie. De minor Retorica bestudeert de…

Begin april trad Ton van Haaften aan als nieuwe Dean van de Honours Academy. Het is nu aan hem om de pioniersfase om te zetten in een consolidatiefase en het honoursonderwijs daarmee een standaardonderdeel van het Leidse onderwijsaanbod te maken. Nu zijn eerste maanden er op zitten, blikt hij vooruit…

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

Indicators to measure progress in de-linking economic growth and environmental pressure.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

DNA carries various forms of information. Out of these forms of information the most well-known is classical genetic information.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

G protein-coupled receptors (GPCRs), one of the largest families of membrane proteins, are responsive to a diverse set of physiological endogenous ligands including hormones and neurotransmitters.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

Bacteria often experience external challenges, such as changes in environmental conditions or attacks by bacteriophages.

Invasive lobular carcinoma (ILC) is the second most common type of breast cancer.

The idea of citizens and public professionals collaborating to provide public services has widely spread in several countries around the globe. Co-production is often presented as the go-to solution for challenges like a legitimacy crisis of both the government and the market, and financial concerns.…

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

This thesis investigates the application of deep learning techniques in image analysis across various domains, focusing on four main themes: feature extraction, classification, segmentation, and integration, demonstrating the transformative potential of these technologies.

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

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.
