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

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

An algorithm is discussed to compute the exponential representation of principal units in a finite extension field F of the p-adic rationals.

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

Freshwater biodiversity has been threatened by eutrophication due to excessive nutrients in the environment. Releasing the freshwater species from such pressures requires efforts from industry and manufacturers to avoid emissions to vulnerable and high-risk regions.

This thesis consists of three papers that are centered around the common theme of Hausdorff uo-Lebesgue topologies and convergence structures on vector lattices and on vector lattices and vector lattice algebras of order bounded operators.

The main object of study in this thesis is an Arakelov inequalitywhich bounds the degree of an invertible subsheaf of the direct image ofthe pluricanonical relative sheaf of a semistable family of curves.

Forming at the nodes of the Cosmic Web and growing hierarchically via mass accretion, galaxy clusters are the largest virialized halos in our universe, composed of dark matter (DM; ≥85%), ionized hot plasma in the intracluster medium (ICM; ≥10-15%), and galaxies (≥1-5%).

This thesis provides explicit expressions for the density functions of absolutely continuous invariant measures for general families of interval maps, that include random maps and infinite measure transformations, not necessarily number systems.

In this thesis, we aim to shed light on the diverse and often opposing roles of integrin α3β1 in cancer.

This thesis covers several aspects of quantum algorithms for near-term quantum computers and its applications to quantum chemistry and material science.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

Explaining treatment response variability between and within patients can support treatment and dosing optimization, to improve treatment of individual patients.

This thesis investigates the evolution and fate of gaseous exoplanets, which are continuously shaped by stellar activity across both short and long timescales.

Supply risks are not new. But the aggravation of power conflicts on the international stage coupled with global shifts towards energy transition and digitalization has triggered the next supply risk research era.

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.

Soil biodiversity is of great importance for the maintenance of multifunctionality in terrestrial ecosystems.

Quantum computers are a proposed fundamentally new type of computer. They aim to perform some computations much faster than previously possible by exploiting phenomena at the quantum scale, called superposition and entanglement.

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?

In this dissertation (titled: Exploring the Synergies between Transfer in Reinforcement Learning and Procedural Content Generation) we explore how the two research fields named in the title, namely Transfer in Reinforcement Learning (TRL) and Procedural Content Generation (PCG) can synergize togethe…

What are the pressing issues of our time, and how can different disciplines come together to address them? Studium Generale and Leiden University College (LUC) present the Global Challenges series: events that bring together researchers from LUC and experts from other disciplines to tackle a shared…

De Psychologie Research Seminars worden georganiseerd door en voor medewerkers van het instituut. Ze bieden de gelegenheid om kennis te delen, nieuwe inzichten op te doen en collega’s vanuit verschillende disciplines te ontmoeten.

Tijdens het najaarssemester (september-december) biedt het NIMAR een Engelstalige minor die zich richt op de studie van Marokko vanuit sociaalwetenschappelijk en geesteswetenschappelijk perspectief. Het semester onderwijst etnografische onderzoeksvaardigheden in een Marokkaanse omgeving.

It researches (the possibilities for) the development of a set of principles and best practices for insolvency office holders by comparing multilateral treaties and soft law recommendations and national legislation within Europe.

What is the effect of light at night on plant phenology and physiology, and how does this affect plant interactions with other species?

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.

Polycyclic aromatic hydrocarbons (PAHs) are the most abundant class of organic compounds in space. The PAH field evolves from the constant interaction between experimentalists, theorists, modellers and observers. While laboratory research and quantum chemical calculations together set up the molecular…

In human cells, a meter-long DNA is condensed inside a micrometer-sized cell nucleus. Simultaneously, the genetic code must remain accessible for its replication and transcription to functional proteins.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

In meta-analysis, heterogeneity often exists between studies. In such cases, it is essential to investigate the sources of heterogeneity and understand the relationship between effect size and study characteristics (i.e., moderators).

The study of orchid flowers, fruits, and inflorescences is crucial due to the remarkable diversity of orchid species and their unique adaptations to pollinators and seed dispersers. However, our understanding of the evolution and development of these organs within the orchid family remains limited.
