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

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

Predictive maintenance (PdM) is a maintenance policy that uses the past, current, and prognosticated health condition of an asset to predict when timely maintenance should occur.

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.

Doordat markten in toenemende mate zijn geïnternationaliseerd, zijn (sub-)nationale toezichthouders ook steeds vaker internationaal actief. Binnen vormen van internationale netwerksamenwerking wisselen deze toezichthouders onderling informatie uit en onderhandelen ze over internationale standaarden…

This thesis seeks to combine two different research topics; Multi-Objective Optimization and Complex Network Analysis.

This thesis applies data mining in commercial settings in the telecommunications industry.

Parkinson's disease is the second most common neurodegenerative disease in the world. One of its symptoms is the loss of dopaminergic neurons in the substantia nigra pars compacta.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Constraint multi-objective optimization with a limited budget for function evaluations is challenging. This thesis tackles this problem by proposing new optimization algorithms. These algorithms are applied on holistic ship design problems. This helps naval architects balance objectives like cost, efficiency,…

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

Stars and planets form within cold, dense clouds of gas and dust drifting through interstellar space. Although dust makes up only a small fraction of this material, it plays a key role in shaping the chemical evolution of these environments.

The field of exoplanet research is rapidly advancing through the development of new technology, observing techniques, and post-processing methods.

Immunotherapies for cancer are an emerging class of therapeutic strategies which aim to treat cancer via augmentation of the immune system.

This thesis is concerned with the constitution of chiral responsive matrix assemblies that may undergo light-driven conformational changes and self-select vibrations to develop vibronic states for driving semi-classical coherent transfer with nearly 100% yield in a lossless NCAP process.

Het onderzoek van de Intelligence and Security Studies Group naar inlichtingen en veiligheid draagt bij aan academische kennis, voedt de publieke discussie, ondersteunt ons onderwijs en de ontwikkeling van professionele praktijk.

On the largest scale, the Universe resembles a cosmic spiderweb. Most galaxies coexist in small groups within the threads of this web. At the nodes of the threads are enormous groups of galaxies forming the largest structures in the universe still held together by gravity: clusters of galaxies.

Artful Mathematics: The Heritage of M. C. Escher

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

This thesis investigates a pharmacological challenge model induced by Toll-like receptor 7 (TLR7) activation, focusing on skin inflammation and its implications for early drug development.

The type-IV secretion system (T4SS) is a machinery able to transfer DNA and proteins between bacteria and in certain cases also to eukaryotic cells.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

This thesis describes the genetic and prokaryotic diversity of giant barrel sponges.

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

In de onderzoekslijn Geneesmiddelenonderzoek werken we voornamelijk met knaagdieren. Knaagdieren, zoals muizen, worden veel gebruikt als proefdier. Deze kleine zoogdieren zijn makkelijk te houden en planten zich snel voort.

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

Optical projection tomography (OPT) is a tomographic 3D imaging technique used for specimens in the millimetre scale.

Deze uitgave is het eerste integrale overzichtswerk op het gebied van fraude en fraudebestrijding waarin wetenschappers én praktijkmensen de belangrijkste aspecten van fraude, fraudepreventie en fraudebestrijding analyseren.

Dissolving microneedles are a subgroup of microneedle types that completely dissolve within the skin. During this dissolving process the vaccine, stored in the needle matrix, is released into the skin.

This thesis utilises the exceptional sensitivity and resolution of LOFAR to explore the low-frequency Universe, while simultaneously advancing the telescope's capabilities to enable new scientific discovery.

The recently introduced nature-originated deep eutectic solvents, so-called natural deep eutectic solvents (NADES) are considered as truly green solvents, which composed of natural ingredients found abundantly in organisms.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.
