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’.

De eerste ILS Lunch Seminar van 2017 staat gepland voor maandag 30 januari. Tijdens de ILS Lunch Seminars kunnen alle onderzoekers van de faculteit hun onderzoek presenteren. Het doel is om op een toegankelijke en efficiënte manier op de hoogte zijn van onderzoeken van verschillende onderzoeksprogramma's…

Video games have emerged as one of the most interesting media of the turn of the century. The peculiar characteristic of video games is the biunivocal interaction between the computer and the human player.

The present thesis focuses on the pharmacological concept of drug-target interaction, which dates back to the beginning of modern pharmacology.

In analogy to mathematical proofs, the goal of a proof system is for a prover to convince a verifier of the correctness of a claim.

This thesis takes steps toward understanding the interaction between gas-phase and solid-state molecules in star- and planet-forming regions.

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

During the development of the (human) body from a single fertilized egg, organs and structures must form. The development and growth of biological forms is called morphogenesis.

In this book liposomes are explored as delivery system for allergen-specific immunotherapy. Both cationic and anionic formulations are prepared with Bet v 1, one of the allergens in birch pollen.

Schimmels die zich in vanilleplanten nestelen, spelen een rol bij het ontstaan van de smaak en geur van vanille. Dat blijkt uit onderzoek van Shahnoo Khoyratty van het Instituut Biologie Leiden. Promotie op 27 oktober.

The largest structures in the Universe are clusters of galaxies. Each can contain hundreds to thousands of galaxies.

In this thesis, I studied the origin and evolution of the non-thermal radiation in merging galaxy clusters.

Het Sport Data Center doet onderzoek binnen vijf thema's.

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

The aim of this thesis was to develop novel treatment strategies for different types of eye melanoma utilizing zebrafish models. We first establish orthotopic and ectopic xenograft models for uveal and conjunctival melanoma by engraftment of the immortalized cells derived from these tumors into zebrafish…

We use DNA strands to stabilize few-atom silver clusters, which show unique optical and chemical properties. This thesis involves the study of these constructs for various applications.

De Universiteit Leiden heeft heel veel te bieden. Kom kijken, we ontvangen u graag!

We showed that constitutive and inducible chemical and morphological defenses against Western flower thrips differ between tomato and chrysanthemum plants.

The aim of this thesis is to develop and study a robust and adaptable scaffold for supramolecular polymer self-assembly in water.

Gold nanoparticles show surprisingly strong interactions with light in the visible range, which can be divided into scattering, absorption, and photoluminescence.

Drug-target binding kinetics determine the time course of the central event in pharmacotherapy: Drug-target interaction.

This thesis focuses on two processes involved in fighting infections: metabolism and immune cell motility and navigation.

Pericytes, the mural cells of blood microvessels, are important regulators of vascular morphogenesis and function that have been postulated to mechanically control microvascular diameter through as yet unknown mechanisms.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Detecting nanoscopic objects plays an important role in nanoscience in particular, in the rapidly growing field of nanobiology. The forebear to modern super-resolution microscopy for single molecule investigation, is fluorescence microscopy.

In this work the reconstruction of a tau neutrino signal in the KM3NeT detector is discussed.

The research group Science Communication and Society aims to understand how science communication works to improve the interaction between science and society. Central themes are ‘Bridging the gap between experts and the general public’ and ‘Evaluating Science Communication’.

This work has described synthetic strategies towards well-defined structures resembling capsular polysaccharide (CPS) fragments, CPS mimics, teichoic acid (TA) fragments as well as a third-generation ring-closing tandem metathesis (RCM) linker to better exploit the potential of automated synthesis.

Langs de randen van de Afrikaanse Serengeti groeide de bevolking de afgelopen tien jaar met vierhonderd procent. Het aantal wilde dieren daarentegen nam drastisch af. Van sommige diersoorten bleven er minder dan een kwart over. Ecoloog Michiel Veldhuis onderzoekt of het tij nog te keren is. Hij vertelde…

How should jurisdictions, both on the national and on the supra-national level, handle the interaction between public and private law where it regards the regulation of financial markets?

How and to what extent the historic house (re-)constructs identity through image-making in China.

Atoms and molecules are the basic units of matter. If we keep dividing a bar of gold or a glass of water into smaller parts, at the end we are left with a single gold atom or a water molecule.

This thesis is a collection of experimental attempts to enhance photoluminescence of fluorescent molecules and quantum dots with single gold nanorods (GNRs) and relevant applications.

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.

The plant hormone auxin regulates plant growth and development through polar cell-to-cell transport-generated maxima and minima. PIN FORMED (PIN) auxin efflux carriers determine the direction of this auxin flow through their asymmetric placement on the plasma membrane (PM).

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Mechanical metamaterials are carefully engineered materials whose properties are controlled by their structure, not by their composition, which allows using metamaterials to study and control physical effects in detail⁠.

The effects of anthropogenic noise on interactions between predators and their prey are still little understood.
