On the 10th of January, Astrid van Winden successfully defended a doctoral thesis. The Leiden University Centre for Linguistics congratulates Astrid on this achievement!

The ultimate aim of the project is to find out whether there are such things as

Leidse milieuwetenschappers doen onderzoek naar microplastics, bestrijdingsmiddelen en bemesting. En binnenkort naar lichtvervuiling en nieuwe materialen uit de nanotechnologie.

Artin L-functions associated to continuous representations of the absolute Galois group G_K of a global field K capture a lot of information about G_K as well as arithmetic properties of K.

Unmanned aerial vehicles (UAVs), often referred to as drones, have become easy and inexpensive to buy, and it is generally expected that the use of drones by private individuals, businesses and public authorities will increase tremendously in the coming years. This raises questions as to what is technologically…

Is the quality of the current supervision and enforcement by the government such that companies that work with large quantities of hazardous substances are brought into compliance with legislation and regulations?

Biodiversity enables ecosystems to thrive through the synergy of functional differences among organisms. While human well-being strongly depends on biodiversity-driven ecosystem services, human actions are also at the root of current unprecedented biodiversity declines.

Our ability to learn and control movements is essential for engaging in goal-directed behaviour. From buttoning your shirt and driving a car, to cooking dinner and brushing your teeth -- our actions in daily life rely on this ability.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

When a physical system possesses symmetries, these are often accompanied by a representation of the symmetry group on a Hilbert space. Group representations on Hilbert spaces have been extensively studied.

On 12 April 2022 Alok Oak successfully defended a doctoral thesis and graduated.

To what extent did The Netherlands' attitude towards European integration change after the 2005 referendum on the European Constitution?

Globally and regionally, biodiversity is declining and there are shifts in species’ occurrences and functional traits.

Wetland plants are distinguished from plants of other terrestrial ecosystems by their adaptations to specific habitat stresses, including waterlogged and flooding and the subsequent abundance of phytotoxic compounds.

In this thesis, time-lapse fluorescent microscopy plays a pivotal role in investigating functional materials within living cells as well as the migratory behaviour of neural progenitor cells.

Due to their central physiological roles in living organisms, retaining beta-glycosidases have been the subject of tremendous research efforts to examine their structure/function relation using numerous biophysical and biochemical approaches.

Acidobacteria is a widely distributed phylum but their functional roles in ecosystem processes are still largely elusive.

Single-layer graphene (SLG) has attracted considerable interest as a proton exchange membrane for direct methanol fuel cells (DMFCs), owing to its atomic thickness, mechanical robustness, and unique proton permeability.

Metals surfaces form a group of effective catalysts for the reaction of small molecules such as hydrogen (H2).

The work presented in this thesis addresses the role of the locus coeruleus (LC) - norepinephrine (NE) system in various aspects of human cognition, and the modulation of brain state.

Managing Diversity: Supervising Functions in Managing Colonial Workplaces

This publication by Cornelis van Tilburg, will be published at Sidestone Press on September 28, 2022. It discusses various aspects of city gates in the Western Roman Empire: Italy, Spain, Gaul, Germany and Britain.

This thesis describes our search to identify and understand possible regulatory mechanisms of integrin α6β4 in cell-matrix adhesion and intracelular signaling.

Advanced sensing techniques require graphene with high quality and well-controlled surface chemistry.

How do plants lure microscopically small 'support teams' into their roots for protection against diseases? And what functions are activated in the microbes and the plants?

The factors that dynamically sculpt the inter-regional correlation of brain patterns are poorly understood. Here, we test the hypothesis that they are shaped by the catecholaminergic neuromodulators norepinephrine and dopamine.

This dissertation presents the results of the importance of creativity for ICT-students of Dutch universities of applied sciences (in Dutch: hogescholen), and the functioning of training courses that aim to promote creative abilities is highlighted.

The function of TLRs in innate immunity has aroused worldwide attention soon after its discovery. Because of the broad functions of TLR2 in innate immunity, the drive for the development of TLR2-targeted vaccines or therapeutic treatments has accelerated in the last decades.

In light of climate change, it is crucial to determine whether plant species can adapt to future climates to avoid extinction. Plants adapt to various conditions by altering their functional traits, such as leaf size or photosynthetic rate. Some traits appear linked and vary together between species,…

Bacteriophages, or phages for short, are the most abundant biological entity in nature. They shape bacterial communities and are a major driving force in bacterial evolution.

My PhD thesis investigates the ecological significance of resistance against drought-induced air bubble formation inside the water conduits of plants (embolism), and the plasticity and functional aspects of stem anatomical traits in woody and herbaceous species.

Green infrastrucuture (GI) like urban farm and green roofs could provide many beneficial functions in cities. These include for example food production, flood prevention or increasing biodiversity. MultiGreen project aims at developing an integrated modelling tool to support…
