With the advent of multicore processors and data centers, computer hardware has become increasingly parallel, allowing one to run multiple pieces of software at the same time on different machines. Coordination of these pieces is best expressed in a coordination language as an explicit interaction protocol…

This thesis describes how to scale down concepts of macroscopic mechanical metamaterials to the thermal scale using a system of flexibly-linked colloids.

This thesis is a (biased) journey through very different topics in astrophysics: quasars and new populations of active galactic nuclei, gravitational waves from merging black holes, and protoplanetary discs around young stars.

This dissertation investigates how the efficiency of Computed Tomography (CT) can be improved for dynamic scientific and industrial applications.

Dit academisch jaar zal de Leiden Socio-Legal Series (LSLS) van start gaan! In deze reeks van 10 lezingen zal maandelijks een jurist(e) aan de hand van zijn of haar eigen onderzoek aangeven op welke wijze het rechtssociologisch perspectief – in theoretische en/of methodologische zin – daarbij een rol…

Taalkundige Johan Rooryck gaat onderzoek doen naar leervermogen en kernkennissystemen, en hoe bezit in verschillende talen wordt uitgedrukt. Samen met collega-onderzoekers heeft hij twee NWO-subsidies van in totaal 2,75 miljoen euro ontvangen voor de onderzoeksprogramma’s ‘Knowledge and Culture’ en…

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 en instituten. Gedurende een seminar van een uur zullen twee of drie sprekers…

ILS organizes a new lunch seminar series where all researchers from Leiden Law School can present their research. The idea is to hear in a simple and nice way what researchers from other research programs and institutes are working on. During a seminar two or three speakers will present their research.…

Afgelopen weekend heeft Italië aan Nederland verzocht twee schepen terug te roepen die onder de Nederlandse vlag varen voor de Libische kust.

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

The research of the Applied Mathematics cluster is concerned with such diverse topics as dynamical systems, representation theory, differential equations and pattern recognition.

This thesis combines field and laboratory studies to address some of the most pressing questions in the field of microplastic research.

This thesis describes the implementation and on-sky demonstration of high-resolution integral-field spectroscopy for extreme adaptive optics systems that are used to find and characterize exoplanets.

When a star is born in our Galaxy, it is quite likely that it has formed within a massive cluster, which hosts numerous high-mass stars bathing their lower mass neighbours in UV radiation.

The research provides insight into disease behavior in both rural and semi-urban areas in Serengeti in Tanzania.

Artificial intelligence algorithms govern in subtle, yet fundamental ways, the way we live and are transforming our societies. The promise of efficient, low‐cost or ‘neutral’ solutions harnessing the potential of big data has led public bodies to adopt algorithmic systems in the provision of public…

Quantum computing represents a fundamentally new computational paradigm, capable of addressing problems that are intractable for classical computers.

The LIACS Media Lab has received a research grant from the worldwide leading graphics hardware company NVIDIA. The grant exists of newly developed hardware utilizing thousands of processors. LIACS researchers will use it to investigate deep learning in understanding imagery from sources such as MRI…

Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…

The path to rational drug and dose selection

This interdisciplinary minor addresses sustainabilty challenges from a systems perspective, and investigates ways to sustain society within planetary boundaries.

Op vrijdag 24 maart aanstaande zal Prof. Amanda Perry–Kessaris (Kent Law School) de maandelijkse Leiden Socio-Legal Lecture verzorgen.

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

Subproject of the ERC project 'Challenging the Liberal World Order from Within: The Invisible History of the United Nations and the Global South'.

This thesis presents the results of a study on the interfaces of insulating oxides with and without the insertion of a magnetic layer.

Cardiovascular disease is a major global burden and atherosclerosis is the main underlying pathological process.

Freshwater and brackish water ecosystems are arguably the most vulnerable ecosystems on earth, due to concentrated human developments in and around them. The Pontocaspian (PC) region located at the border of Europe and Asia contains a variety of brackish water ecosystems and unique inhabitants, known…

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.

We developed the bitterling as a unique, well-studied model organism in the area of the evolutionary ecology of brood parasitism. The bitterling-mussel relationship, interspecific mussel host preference, and mussel gill structure are studied in detail, to help understand the developmental adaptation…

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.

A complex community of microbes develops in the infant gut shortly after birth. We call this community the infant gut microbiota. The microbiota influences the health of the infant, which makes the composition and function of the infant gut microbiota an important topic to study.

This thesis is a collection of theoretical works aiming at adjusting quantum algorithms to the hardware of quantum computers.

The subject of this thesis, ‘Approach to Markov Operators on Spaces of Measures by Means of Equicontinuity’, combines an analytical and probabilistic approach to Markov operators.

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).
