Wouter Verschoof-van der Vaart verfijnt een kunstmatige intelligentie-systeem dat zelfstandig archeologische objecten op digitale beelden kan detecteren en classificeren. Zo’n systeem is broodnodig, want menselijke archeologen worden wereldwijd overspoeld met data.

Een lijst met wetenschappelijke publicaties samengesteld door het team van het TRIXY Expertisecentrum.

Net als de profwielrenners van Team Jumbo-Visma kan ook de amateurwielrenner straks zijn prestaties analyseren en verbeteren. Leidse datawetenschappers die samenwerken met de wielerploeg stellen hun slimme datamodel beschikbaar, zodat voortaan elke serieuze wielrenner kan bijhouden hoe fit hij of zij…

Zeven bachelorstudenten Informatica aan de Universiteit Leiden werken mee aan een onderzoeksproject rond big data en eventmanagement. Hun werk moet uiteindelijk resulteren in een systeem dat gebruikt kan worden bij de finish van de Volvo Ocean Race in Den Haag in juni volgend jaar.

Workshop

Een mix van dataonderzoek, kunstmatige intelligentie en archeologie zorgde op 31 januari voor levendige discussies. Op die dag vond het seminar ‘AI & Data Science @ Archaeology’ plaats, waar het Data Science Onderzoeksprogramma (DSO), SAILS en de Faculteit Archeologie hun krachten bundelen.

How were the Russians, under early modern conditions, able to incorporate this distant, undeveloped and, because frequent nomadic attacks, dangerous territory? And what role did the Kolyvan-Voskresensk plants play in this process?

Een interdisciplinair consortium van Universiteit Leiden, de Universiteit van Amsterdam (UvA) en het Centraal Bureau voor de Statistiek (CBS) ontvangt 1 miljoen euro voor de aanleg van een open digitale infrastructuur voor netwerkanalyse van de gehele Nederlandse bevolking. Dit stelt wetenschappers…

Cardiovascular diseases are among the most frequent causes of death in the world. The main underlying pathology of cardiovascular diseases is the development of atherosclerosis in the medium and large-sized arteries.

Understanding DNA repair mechanisms is essential for advancing plant biotechnology and crop improvement. This study investigates how double-strand breaks (DSBs), induced by CRISPR/Cas systems, are repaired in the model plant Arabidopsis thaliana, and how these processes influence Agrobacterium tumefaciens…

Carbonaceous asteroids preserve a record of early solar system processes, where minerals and organic molecules, like polycyclic aromatic hydrocarbons (PAHs), offer clues to planetary evolution and prebiotic chemistry.

An Active Galactic Nucleus (AGN) is a highly luminous region at the center of a galaxy, powered by the accretion into a supermassive black hole and emitting energy from radio waves to gamma rays, often outshining the host galaxy.

Ferritin is a spherical metalloprotein, capable of storing and releasing iron in a controllable way. It is composed of a protein shell of about 12 nm and within its cavity, iron is stored in a mineral form.

International trade has played a major role in defining the modern global economy. Trade, however, entangles the environmental pressures of economic sectors, giving the illusion of environmental improvements, while the opposite may be occurring.

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.

Barrier function is the natural role of the skin. The lipid matrix present in the outermost layer of the skin, the stratum corneum is important for this function.

Bacteria have the ability to alter their morphology in order to adapt to changing environments.

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.

This thesis describes the development and optimization of the first molecular tools to study the enzyme PLA2G4E.

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.

The human body consists of hundreds, perhaps thousands of different types of cells, each with different morphologies and functions, despite having the same genome.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

In the current global context, there is a pressing need to address sustainable energy supplies to safeguard our Planet and its ecosystems. The choices made by human society have a significant impact on genetic evolution and climate.

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

Catharanthus roseus (Madagascar periwinkle) produces valuable monoterpenoid indole alkaloids (MIAs) such as vincristine and vinblastine, crucial for cancer treatment.

Prostate cancer (PCa) is one of the most prevalent cancer in males.

This thesis investigates opinion dynamics on random graphs through the lens of the voter model, a classical interacting particle system used to describe how consensus emerges in networks.

Kinase inhibitors are key therapeutic agents, particularly in oncology, yet their clinical efficacy is often hampered by off-target effects and limited understanding of their cellular target profiles.

In this thesis, rational points on K3 surfaces are studied. In the first part of Chapter 1 the Brauer group and the the Brauer-Manin obstruction are introduced.

Advanced UHF MRI techniques provide powerful tools for studying the zebrafish brain, an emerging model in neurological research. In this work, various MRI and localized MRS methods are optimized and employed for UHF strength for studying the zebrafish brain.

The research aims to explore the evolutionary adaptability of enzymes and the impact of temperature on protein evolution pathways, using M. tuberculosis β-lactamase BlaC as the object of study. Enzymes inherently embody a delicate balance between activity and stability, and the acquisition of new enzymatic…
