The lipid matrix of the skin's stratum corneum plays a key role in the barrier function, which protects the body from desiccation. The lipids that make up this matrix consist of ceramides, cholesterol, and free fatty acids, and can form two coexisting crystalline lamellar phases: the long periodicity…

This thesis aimed to investigate core cross-linked polymeric micelles (CCPMs) and expand their potential for the delivery of hydrophobic drugs and co-factors.

On the 15th of July Sawako Takemura successfully defended a doctoral thesis and graduated.

The four possible segments A, T, C and G that link together to form DNA molecules, and with their ordering encode genetic information, are not only different in name, but also in their physical and chemical properties.

The outermost layer of the skin, the stratum corneum (SC), is responsible for the skin barrier function, protecting the body from pathogens, chemicals and other unwanted substances from the external environment. The SC lipid matrix provides the only continuous pathway through the SC and is considered…

Psychologist Bernadet Klaassens initiated a large fMRI study on the effect of drugs on brain networks in aging and Alzheimer's disease. It generated a unique data set and insight into a new method to develop drugs for patients with Alzheimer's.

Form and Function in Greek Grammar. Linguistic Contributions to the Study of Greek Literature is a new book, written by Albert Rijksbaron. Rijksbaron is internationally known as one of the leading scholars of the Ancient Greek language, whose work has exerted a strong and lasting influence on the scholarly…

In this thesis, I study 1) metabolic alterations in tuberculosis related to wasting syndrome in human patients as well as in rodent and fish animal models. 2) effects of the mutation of the leptin gene on cachexia and diabetes in rodent and zebrafish animal models.

To argue that people can control the relative contributions of goal-driven and stimulus-driven processes to decision-making and action selection.

This study is the first to directly relate brain development to sex differences and school performance. The results debunk the myth that brain development is slower in boys.

To what end and how does Plautus constantly underline the Helleni(sti)c provenance of his art? How does this aspect relate the author’s originality?

The aim of this thesis was to study the link between hearing loss, language skills, and social functioning in deaf and hard of hearing (DHH) children. Sufficient language skills are an essential prerequisite to develop appropriate communication skills, in order to join in conversations with others.…

On the 20th of June, Camil Staps successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Camil on this achievement!

What are the precise identities, possibilities and current practice examples of the various time frames in music and what bearings do they have individually and in combinations on the speed of the music?

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.

An international partnership of brain researchers from 35 research centres - from the US to China - including the Leiden Institute for Brain and Cognition (LIBC), has collected resting-state functional MRI data from more than 1400 healthy volunteers and put the information online so that it is available…

Are disturbances to the brain, such as Alzheimer's or autism, linked to specific defects in the underlying communication networks in the brain? If this is the case, subtle changes in the networks can act as a marker for brain disturbances. Neuroscientist Serge Rombouts will be investigating this, together…

In this thesis, deep learning is studied from a statistical perspective. Convergence rates for the worst case risk bounds of neural network estimators are obtained in the classification, density estimation and linear regression model.

Within the field of astronomy, understanding how galaxies grow and evolve from the Big Bang to the present day is a challenging and complex question.

The formation of stars and planets happens over multiple scales, which can interact. In particular, planet formation happens in the dense, complex environment of star forming regions.

This project incorporates spatiality into the discussion of medieval demography, allowing for a more nuanced view on medieval town populations. It establishes a maximum population count for towns for periods prior to 1400 and provides a means to compare the ranking of towns using size and density instead…

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

Together with a large international team of scientists, researchers Peter van Bodegom and Nadia Soudzilovskaia of the Leiden Institute of Environmental Sciences (CML) have created maps of variability in plant trait distribution across the globe. The new maps have been published in Proceedings of the…

PURPOSE: To monitor the biodistribution of IgG1 aggregates upon subcutaneous (SC) and intravenous (IV) administration in mice and measure their propensity to stimulate an early immune response.

One of the most important correlation functions in physics, especially in cosmology, is the energy density, which describes how much energy is present at each point in spacetime due to matter fields. A key contribution to the energy density of the primordial universe comes from gravitational waves (GWs),…

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.
