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

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

This dissertation contains four works during my PhD. Different biomaterials have been designed based on coiled-coil peptides. These biomaterials have a range of applications, inclusing drug delivery, cell sorting to cell-cell fusion.

The work in this thesis describes the fundamental role of Lkb1 as a conductor of metabolism-related processes in zebrafish larvae.

Carbohydrates, alongside proteins and nucleic acids, constitute a crucial and versatile family of biomolecules present in all life forms. They manifest as monosaccharides, oligosaccharides, and polysaccharides, covalently bonded to proteins and fats. Carbohydrates are integral to plant and arthropod…

In this work we describe three methods to improve the performance of Quantum Field Theory calculations.

This thesis focused on the exploration of monolayer graphene as a membrane in direct methanol fuel cell (DMFC) applications, with improvements achieved through plasma exposure or damage- free chemical functionalization.

The work in this thesis has been focused on two subjects. The first is the assembly of alginate oligosaccharides and the generation of building blocks for the enzymatic synthesis of alginate, and the second is the total synthesis of large fragments of the zwitterionic SP1 polysaccharide.

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

This thesis focuses on data found in the field of computational drug discovery. New insight can be obtained by applying machine learning in various ways and in a variety of domains. Two studies delved into the application of proteochemometrics (PCM), a machine learning technique that can be used to…

Many of our department’s staff members are actively involved in the Empirical Legal Studies lab and strive towards publishing impactful empirical legal research.

Dr. Bela Bode ontvangt van de Alexander von Humboldt-stichting de Feodor Lynen onderzoeksbeurs voor de ontwikkeling van nieuwe methoden voor verbetering van het signaal in de vaste stof NMR. Hij streeft naar een specifiek analytisch instrument voor oppervlakte-studies en onderzoek over membranen en…

Urbanisation is steadily increasing with estimates expecting that 68% of the global population will live in cities by 2050. To accommodate the rural to urban transition, large quantities of land are transformed from natural to urban lands.

This interdisciplinary minor addresses sustainabilty challenges from a systems perspective, and investigates ways to sustain society within planetary boundaries.

How does one become a guest author for Nobel Prize winner Dr. Denis Mukwege Foundation? One of our alumni, Mariasole Forlani, can tell you all about it.

How and to what extent the historic house (re-)constructs identity through image-making in China.

Aan de Universiteit Leiden worden cursussen over papyri en papyrologie aangeboden voor beginners en gevorderden (BA en MA), zowel op basis van teksten in vertaling als in de originele brontalen, van Egyptisch tot Grieks, Latijn en Arabisch.

Every organisms in the tree of life faces the same challenge: the length of its DNA exceeds the volume of the cell it needs to fit in. Several strategies have evolved to solve this problem, one of them being the expression of proteins that bind and organize the DNA.

During post-embryonic development into adults, animals face an environment that fluctuates constantly. For example, in nutrient availability, temperature, and osmolarity (e.g., salt concentration).

This dissertation studies the Asymptotics of Bayesian nonparametric inference for Gaussian linear models.

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.

This thesis describes a study from both a theoreticaL and an experimental point of view.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

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

In times of hardships or crisis, local people know how to deal with it using their resourcefulness. Although efforts are sometimes made by the government to help them, they are fully aware that community support is at least equally important.

This dissertation is about Bayesian learning from data. How can humans and computers learn from data?

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.
