To answer questions that look beyond individual entities, network science studies the interactions taking place in complex systems. These complex systems can often have temporal information on when an interaction occurs.

In astronomy, the interpration of observations and measurements plays a crucial role: we rely purely and fundamentally on the information that reaches us as observers. And 80% of all matter in the universe is undetectable directly.

The demand for neodymium-iron-boron (NdFeB) magnets is rapidly growing, while the neodymium supply chain is under pressure. Recycling can alleviate these issues. This thesis investigates the potential for deploying novel magnet recycling technologies and their environmental consequences.

Het Prisonproject gaat na in hoeverre een gevangenisstraf gevolgen heeft voor onder andere recidive, gezondheid, beroepsloopbanen en intieme relaties van (ex-)gedetineerden.

Schaatscoach en bewegingswetenschapper Jac Orie legt al vijftien jaar alles vast over de prestaties van 'zijn' schaatsers. Dankzij datawetenschapper Arno Knobbe, die de verzamelde data op nieuwe manieren doorberekent, kan Orie zijn team nog slimmer trainen in de aanloop naar de Olympische Winterspelen…

Gold nanorods are biocompatible nanoparticles that present an excellent two-photon signal that can be used to get high spatial resolution inside living cells. Gold nanorods are photostable and therefore can be followed inside cells for long time, with possible applications as trackers in live cells.

The deeper understanding of an organism's pathology is important for developing treatments. Over centuries of systematic research, clinical researchers have demonstrated that the more information they acquire about the cellular properties and their organisation in the tissue, the better they can understand…

The skin is our natural barrier and lipids are a key part of this barrier. In the outer skin layer, the stratum corneum (SC), lipids form a densely organized structure dependent on the composition of these lipids.

This thesis investigates the contribution of quantum computers to machine learning, a field called Quantum Machine Learning. Quantum Machine Learning promises innovative perspectives and methods for solving complex problems in machine learning, leveraging the unique capabilities of quantum computers…

The power of personalized nutrition lies in being able to conduct clinical research on healthy people while capturing metabolic markers sensitive to the impact of environmental and metabolic stressors (e.g. diet, changing sex hormones and the menstrual cycle).

Veel Nederlandse schaatsers en voetballers behoren tot de absolute wereldtop. Toch kunnen ze dankzij slimme statistische analyses wellicht nóg een beetje beter worden. De Universiteit Leiden werkt er samen met Delft en Amsterdam aan.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

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

Plants produce an astonishing variety of secondary metabolites (SMs) which are thought to play vital roles in the fitness of plants through ecological interactions.

Twee teams met taalwetenschappers deden onafhankelijk van elkaar onderzoek naar de identiteit van ‘Q’, de persoon van wie wordt verondersteld dat die de complottheorie heeft verspreid. Beide studies lijken te wijzen naar hetzelfde duo.

Woensdag 14 juli publiceerden Nederlandse astronomen een primeur in vakblad Nature. Het was hen als eersten ter wereld gelukt om isotopen te ontwaren in de damkring van een exoplaneet. Een ontdekking die ons meer kan leren over het ontstaan van planeten. Verschillende media schreven over de bijzondere…

This thesis describes how complex and real-world relevant analytical solutions can be found starting from a simple Nagumo problem posed on one or two-dimensional lattices.

Data theory research on the analysis on the multidimensional data

In the era of big data, extracting insights from complex datasets is a key challenge. This thesis demonstrates the superiority of graph-based methods over traditional clustering (e.g., k-means, DBSCAN) and outlier detection for analyzing high-dimensional and noisy data.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

The name ‘Jambi flora’ refers to fossil plants found as part of a rock formation from the Early Permian (296 million years old), located in the Jambi Province of Sumatra, Indonesia.

Real-life processes are characterized by dynamics involving time. Examples are walking, sleeping, disease progress in medical treatment, and events in a workflow.
