This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

Large carnivores and humans, along with their livestock, have co-existed for thousands of years. However, human population growth and an increase in economic activities are modifying the landscape for large carnivores and their prey.

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

S.S. Kolipaka’s thesis questions and investigates the survival prospects of reintroduced tigers and their offspring’s in the human dominated landscape of Panna tiger reserve in India.

This thesis introduces a relational interaction model and a practical tool for describing, visualising and generating interactive dialogues.

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

Mycoheterotrophy is a particular mode of life in which plants obtain carbohydrates from their associated fungal partners, instead of by using photosynthesis.

Biological cells, the basic building blocks of all life forms, are surrounded by a lipid membrane. More than half of the membrane is occupied by membrane proteins, which can regulate the cell functionality through specific arrangements.

The aim of this thesis is to study cell-cell interactions and the development of an assay to explore and quantify the exchange of membrane compounds.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

The lipid membrane is a basic structural component of all living cells. Embedded in this nanometer-thin barrier, membrane proteins shape the membrane and at the same time respond to the shape of the membrane.

This multidisciplinary minor provides students with knowledge on how and why humans became the way they are. The minor focuses on the evolution of the species Homo sapiens from other hominin lineages and animal ancestors, and on the various factors shaping this process. Not only is human evolution of…

Large carnivore population is globally declining as a result of the fragmentation of habitat, large prey depletion and retaliatory killing by pastoralists.

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

Ethiopian wolves are endangered diurnal Afroalpine rodent hunters. I investigated the interaction between wolves, rodents and human land use in Borena Sayint National Park (BSNP), Abune Yosef and Aboi Gara in Ethiopia.

In this project, researchers from computer science, law, psychology, and public administration research in practice how artificial intelligence (AI) can be leveraged to make decision-making in the security domain more effective, while also keeping it safe and accountable.

Cardiovascular disease is the leading cause of death worldwide.

Novel entities may pose risks to humans and the environment. The small particle size and relatively large surface area of micro- and nanoparticles (MNPs) make them capable of adsorbing other novel entities, leading to the formation of aggregated contamination.

Despite substantial progress in understanding tuberculosis (TB), the eradication of the TB epidemic is still far from reach.

Toll-like receptors (TLRs) are central components of the innate immune system, functioning as pattern recognition receptors that detect microbial- and damage-associated molecular patterns and initiate antimicrobial and inflammatory responses.

Duurzaamheid is een van de centrale aandachtspunten van de Universiteit Leiden en speelt een steeds grotere rol binnen het onderwijs en onderzoek van de Faculteit der Rechtsgeleerdheid. Binnen deze context levert de afdeling Sociaal Recht een belangrijke bijdrage aan het debat en onderzoek rondom Business…

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

The studies presented in the work show the potential of the integrative use of biophysical data in defining the structural basis of protein interactions.

Heart failure is a major health care problem with high mortality.

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.

This thesis is devoted to an in-depth examination of the various effects of disorder in the cuprate high-temperature superconductors.

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.

The mycorrhizal symbiosis is among the most widespread species interactions on Earth⁠. This thesis focuses on orchid mycorrhiza, a unique mycorrhizal type that has caught scientists’ attention for centuries⁠.

The thesis describes the use of electron paramagnetic resonance (EPR) spectroscopy, in continuous wave and pulse modes, to address the interaction of α-Synuclein (αS) with membranes and the aggregation of αS.

Human AI is waar kunstmatige intelligentie en machine learning samenkomen met filosofie, cognitieve wetenschap en de creatieve kunsten.

This dissertation aims to advance understanding of amoeboid single cell migration under the influence of changing physicochemical environmental properties. The particular focus is on the relatively unknown influence of differing physical properties in the extracellular environment, such as the migratory…

Een nieuw onderzoek van de Leidse archeologe Anastasia Nikulina en een internationaal team uit Frankrijk, Denemarken, het Verenigd Koninkrijk en Nederland, weerlegt het idee dat jager-verzamelaars vóór de opkomst van de landbouw een verwaarloosbare impact hadden op hun leefomgeving.
