Statistical distributions in LCA and converting between different representations of these distributions.

In this thesis we examine certain phenomena in symplectic topology which are related to the theory of isolated singularities.

Dit boek, geschreven door prof. mr. Bob Wessels (em.) en Ilya Kokorin LLM, , beschrijft en analyseert de Europese insolventieverordening (herschikt) ('EIR 2017’) die inwerking is getreden in juni 2017.

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.

Bacteria are highly complex and diverse organisms that have adapted to survive in ecological niches ranging from the most extreme to the most heterogeneous environments.

Van zwarte gaten tot kunstmatige intelligentie en van medicijnonderzoek tot data science: welkom in de fascinerende wereld van de Faculteit der Wiskunde en Natuurwetenschappen. Geregeld geven onze onderzoekers, studenten en gasten publieke lezingen over hun werk. U bent van harte uitgenodigd.

This dissertation focused on computational methods based on first principles calculations using the Density Functional Theory (DFT) framework. Emphasis was laid on affordable methods that can provide a tradeoff between computational expense and accuracy.

Tijdens de IBL Spotlights bespreken onderzoekers van de afdeling Science Communication & Society hun nieuwste bevindingen en realisaties.

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…

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.

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

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.

Het Instituut Pedagogische Wetenschappen voert onderzoek uit gericht op 6 deelgebieden die gezamelijk het domein dekken van de studie naar normatieve en niet-normatieve ontwikkeling van gedrag, emoties en leren vanaf de jonge kindertijd tot aan de periode van jong-volwassenheid.

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.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

This dissertation revolves around the design and implementation of novel instrumentation and related measurement techniques, at the single molecule level, for use in biophysical research. Chapter 1 presents an introduction to the field of fluorescence-based single molecule measurements. In particular,…

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

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.

The research described in this thesis focused on identifying novel drug targets and synergistic combinations for triple-negative breast cancer (TNBC), a virulent subtype of breast cancer with a dismal prognosis and limited therapeutic options.

Human civilization consumes a huge amount of fossil fuels, which has resulted in an atmospheric CO2 level which has not been higher in over 800 millennia.

Surface acoustic waves (SAWs) are mechanical waves that travel along the surface of a material and find many applications in modern technologies due to the ease of excitation on piezoelectric substrates via interdigital transducers (IDTs).

Overall dispersion in LCA as result of inherent uncertainties, spread and unrepresentativeness.

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

Striga hermonthica, commonly known as witchweed, infests major cereal crops in Sub-Saharan Africa causing severe yield losses and threatening the livelihood of millions of resource poor farmers.

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…
