All the data stored and processed by our computers is encoded as sequences of zeros and ones, called bits. Quantum computers offer an alternative to this traditional way of encoding and manipulating information.

Evolution acts via mutations in amino acid sequences. Substitution of essential amino acids leads to a nonfunctional protein. l.

De Minister van Justitie van Sint Maarten heeft een onderzoek laten uitvoeren naar de jeugdcriminaliteit op Sint Maarten.

The prevalence of obesity (BMI >40 kg/m2) has increased rapidly over the recent years, not only in adults, but also in children and adolescents.

The haplolepideous mosses (Dicranidae) comprise about 4000 species distributed over a wide range of habitats, with great gametophytic and sporophytic morphological variation. Their monophyly is well supported by the results of several molecular phylogenetic studies, which shed light on their relationships…

This PhD thesis concerns the topic of arithmetic geometry. We address three different questions and each of the questions in some way is about counting how big some set is or can be.

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

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

Het doel van het RAISE Onderzoek is om te onderzoeken hoe veerkrachtige mensen omgaan met stress. We kijken specifiek naar hoe belangrijke biologische systemen, zoals de HPA-as en het immuunsysteem, samenwerken met de hersenen en de sociale omgeving om veerkrachtig functioneren na moeilijkheden in de…

The main subject of this thesis is the design and synthesis of paramagnetic molecules for protein studies with NMR and EPR spectroscopy.

What physics controls the properties of quantum matter, such as how electrons flow inside high-temperature superconductors? This question has captivated the physics community and industry for decades, in part due to the great technological potential such materials have, but also because they have resisted…

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

BlaC is the β-lactamase of Mycobacterium tuberculosis. We show that it can recover from inhibition by clavulanic acid and that phosphate helps it do so.

A structural investigation of coiled coil peptides used as membrane fusogens, mimicing naturally occuring coiled-coil fusion proteins. Synthetic modifications have been made to alter lipid attachment, secondary structure and to insert photoactive azobenzene moieties for active control over coiled coil…

Improvements of weak gravitational lensing shape measurements are presented and some used for data analysis.

Waarom kies je voor een master in Leiden? We vroegen het een paar van de bezoekers die op 10 oktober naar de Masterdag van W&N kwamen – soms van ver. Ze luisterden naar presentaties, bezochten de infomarkt, bekeken het gebouw. Ze wilden vooral vragen stellen, sfeer proeven en van studenten en docenten…

Het Leids Universitair Medisch Centrum (LUMC) start vanaf 1 september officieel met de bekostigde en reguliere masteropleiding Vitality and Ageing.

The aim of this thesis is to present novel techniques for proving cryptographic schemes secure against quantum adversaries. Most results are within the context of an idealized model called the ‘quantum random-oracle model’.

Leren samenwerken met mensen van andere disciplines, daar draait het om bij de Master Honours Challenges. In teams pakken studenten een vraagstuk aan voor een organisatie of de samenleving als geheel. Twee deelnemers vertellen wat hun vak bijzonder maakte. ‘Het geeft een bij vlagen ongemakkelijk, maar…

Electrons in a crystal lattice have properties that may differ from those of a free electron in vacuum.

Less than 1 in 10 drug candidates that enter phase 1 clinical trials actually gets approved for human use.

On 8 July, the symposium 'The digital reconstruction of the crucifixion of the Lindau master (ca. 1425)' will take place at the auditorium of Museum Catharijnecovent, from where it will also be broadcasted online.

Op dinsdag 16 april 2019 ontvingen de studievereniging JSV Liberi en de afdeling Jeugdrecht alumni van de master Jeugdrecht tijdens een carrièremiddag en alumni-avond.

Op maandag 1 februari is het tweede semester feestelijk ingeluid op de Sterrewacht. De Afdeling Jeugdrecht en JSV Liberi nodigden twee advocaten uit om te komen spreken over de belangen van de minderjarige in het gezondheids- en vermogensrecht.

Per 1 september 2024 is er geen predicaat cum laude meer voor de master Geneeskunde. Het College van Bestuur besloot onlangs een ontheffing te verlenen voor de faculteit geneeskunde van Universiteit Leiden/LUMC. Het besluit past in de lijn van andere geneeskunde opleidingen in Nederland.

We show that Kirchhoff ’s law of conservation holds for non-commutative graph flows if and only if the graph is planar. We generalize the theory of (Euclidean) lattices to infinite dimension and consider the ring of algebraic integers as such a lattice.

Make more fluid: In condensed matter systems, electrons can acquire unusual properties from their interaction with the atomic lattice.

n this thesis we study curves. In the first half, we study moduli spaces of curves and Gromov-Witten invariants, certain kinds of curves counts. We employ logarithmic geometry for this.

Clinical development of drugs for central nervous system (CNS) disorders has been particularly challenging and still suffers from high attrition rates.

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.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

Global healthcare is on the verge of an antibiotic availability crisis as bacteria have evolved resistance to nearly all known antibacterials. Identifying new antibiotics that operate via novel modes-of-action is therefore of high priority.

Phospholipase A/acyltransferase 3 (PLAAT3) and PLAAT4 are enzymes involved in the synthesis of bioactive lipids. Despite sequential and structural similarities, the two enzymes differ in activity and specificity.

Mechanical forces are known to play an important role in bacterial colonies. In this dissertation, we study the self-organization at various stages of growing bacterial colonies, and focus on the mechanical effects of cell growth.

β-Lactamases are enzymes that can break down β-lactam substrates, such as antibiotics, preventing the use of these antibiotics for the treatment of various infectious diseases. However, some compounds, β-lactamase inhibitors, can block these enzymes allowing for possible treatments using a combination…

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

The physical origin of the dozens of stellar-mass binaries, the mergers of which have been detected by the LIGO-Virgo-KAGRA collaboration via gravitational waves, is still unknown.
