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.

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

Humans perceive the real world through their sensory organs: vision, taste, hearing, smell, and touch. In terms of information, we consider these different modesalso referred to as different channels of information or modals.

Ice, the solid state of water, plays an important role on our planet as well as the entire universe.Despite the fact that an individual water molecule has a very simple structure, its chemical bonding in the solid phase can be surprisingly complex.

This thesis studies the geometry of representation varieties and character stacks. These are spaces parametrizing the representations of a finitely generated group, typically the fundamental group of a compact manifold, into an algebraic group G.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

The focus throughout this thesis will be on gathering fundamental studies of the detailed structure and composition of the electrode/electrolyte interface effect on the rate and mechanism of key electrocatalytic reactions.

Humans can see the world through the eyes of other humans and imagine what they know, want, and intend. This competence is known as Theory of Mind.

Building a Deep Cross-media Transfer Network to extract visual relations that relieve the problem of insufficient training data for visual tasks.

In this thesis I highlight the applications of Oxford Nanopore Technologies (ONT) sequencing. This technique is a relatively new approach in the sequencing field, where nanopores are embedded in a membrane, DNA molecules are pulled through nanopores and an electrical current serving as the sequencing…

This thesis considers multi-prover commitment schemes whose security is based on restrictions on the communication between the provers.

The aromatic infrared bands (AIBs) seen throughout the interstellar medium (ISM) are generally thought to be carried by polycyclic aromatic hydrocarbons (PAHs) and their nitrogen analogues (PANHs).

Cardiovascular disease is the leading cause of death worldwide.

The marine shipping industry is one of the strongest emitters of nitrogen oxides (NOx), a pollutant detrimental to ecology and human health. Over the last 20 years, the pollution produced by power plants, the industry sector, and cars has been decreasing.

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

In this thesis we explore machine and deep learning approaches that address keychallenges in high dimensional problem areas and also in improving accuracy in wellknown problems. In high dimensional contexts, we have focused on computational fluid dynamics (CFD) simulations.

The overarching goal of this thesis is to set the foundations, but also make the first essential steps towards establishing a comprehensive, mesoscopic, hydrodynamic theory of epithelial tissues. The stage is set by an exhaustive study of topological defects in passive p-atic liquid crystals, singularities…

Drug-induced liver injury (DILI) is one of the main reasons for drug attrition during pre-clinical and clinical phases of drug development as well as for drug withdrawal post-marketing.

Over de hele wereld staan koraalriffen onder druk. Zarinah Waheed onderzocht de riffen in Maleisië en komt tot de conclusie dat de bescherming van koraalriffen beter kan. Promotie op 22 november.

De Leidse masterstudent Arend Moerman heeft een tien gekregen voor zijn afstudeeronderzoek naar de simulatie van de chaotische interacties van drie zwarte gaten. Uit de simulaties blijkt dat lichtere zwarte gaten elkaar meestal wegslingeren, terwijl zwaardere vooral samensmelten. Het onderzoek, een…

The book ‘Bestrijdingsmiddelen en Milieu' gives a transparent overview of facts and figures concerning pesticide use in the Netherlands and the impact of pesticides on the environment.

This work describes the use of click-to-release chemistry to get spatiotemporal control over immunocytokine activity. Until now, immunocytokines (cytokines coupled to a tumor-targeting-moiety) remained active throughout the body, being able to bind their respective receptors, causing mild to severe…

While ecosystems have concrete benefits for human society, these benefits are typically overlooked in decision-making.

The first steps are made in personalised cancer vaccination strategies, which aim to induce a more specific immune response with fewer side effects. The activation of cytotoxic T cells is crucial for an effective immune response.

Microscopic insight on lipid-based nanomedicine in vivo remains limited to the perception of the knowledge that could be obtained: if we interpret only what we see, then we only believe to know. Although believing to know encapsulates an undefined amount of uncertainty in the exploration of lipid-based…

This thesis advances our understanding of lipid uptake, a vital first step in lipid metabolism, by developing innovative click chemistry-based tools to study how immune cells internalize lipids.
