The Vallesian, 11.1-9 Ma, was a special time in the Vallès-Penedes basin near Barcelona, where a biodiversity hotspot existed. Europe had a subtropical climate, with rhinos, forest giraffes, lions, hyenas, flying squirrels and primates.

Visualizing the internal structure is a crucial step in acquiring knowledge about the origin, state, and composition of cultural heritage artifacts. Among the most powerful techniques for exposing the interior of cultural heritage objects is computed tomography (CT), a technique that computationally…

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

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

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.

Streptomyces bacteria are a valuable source of natural products, many of which are used in the clinic or in biotechnology.

This thesis investigates how quantum, quantum-inspired, and hybrid quantum-classical computation can enhance key points of the automated machine learning (AutoML) pipeline under the constraints of noisy intermediate-scale quantum (NISQ) devices.

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

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

Women Writing Mexico (WWM) is a network of women and men concerned with the human rights crisis in Mexico and more specifically, with the impact of structural forms of poverty, everyday violence, and discrimination based on gender, race, social class, and ethnicity, that particularly have an impact…

This thesis examines enzyme domain architecture and engineering to improve the breakdown of lignocellulose and starch, abundant biopolymers crucial for sustainable biofuel and biochemical production. Carbohydrate-active enzymes (CAZymes) facilitate this degradation, but the structural complexity of…

The overall objectives of my thesis are to investigate the dynamics of the sorghum root microbiome and to explore the beneficial effects of the root microbiome on sorghum growth and stress tolerance.

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

Plants and soils from natural ecosystems harbor great diversity of soil microorganisms, which could potentially contribute to the sustainability of horticulture. The knowledge about using wild plant species and soil from natural ecosystem to improve the crop health will advance the application of ecological…

This thesis describes the development and validation of new high-contrast imaging techniques, with the ultimate goal of enabling the next generation of instruments for ELT-class telescopes to directly image Earth-like extra-solar planets orbiting around nearby stars.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

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.

Anthropogenic noise negatively affects wildlife in a wide range of taxonomic groups.

This thesis explores how bees and hoverflies are distributed across the Dutch landscape and how ecological and landscape factors shape their occurrence.

This collection of papers was compiled in celebration of the remarkable academic career of Professor Wil Roebroeks, who has established himself as one of Europe’s leading figures in Palaeolithic archaeology over the past three decades and founded the Human origins research group at Leiden University…

Het Leiden University Centre for Linguistics (LUCL) is een gerenommeerd instituut op het gebied van taalkunde. Het biedt uitstekende onderzoeks- en onderwijsmogelijkheden in een breed scala aan talen van over de hele wereld.

Inzichten in opmerkelijke taalverschijnselen en gedetailleerde prijs- en handelsinformatie maken dit boek interessant voor zowel taalkundig geïnteresseerden als belangstellenden in sociale en economische geschiedenis.

Begin 2019 publiceerde de QANU (Quality Assurance Netherlands Universities) een rapport over het Leiden University Centre for Linguistics (LUCL). Deze toetsing vindt elke 6 jaar plaats als onderdeel van de algehele monitoring en borging van de onderzoekskwaliteit in Nederland.

Leiden University offers a unique range of summer courses where you can broaden or deepen your knowledge or share your expertise with fellow students. The choice of academic courses is very diverse, ranging from Law, Big Data, Languages and Linguistics to Maths and Natural Sciences, Biology, Biomedical…

Het boek behandelt de achtergronden van de Hamburgse migrantenfamilie Heusch, oorspronkelijk afkomstig uit Antwerpen, en de intrigerende taalcontactsituatie van de in het Nederlands geschreven brieven. Ook bevat het een uitgave van de brieven met inleiding en toelichting.
