Statistical distributions in LCA and converting between different representations of these distributions.

Settlement burials in the pagus Texandrië and the transformation of Merovingian society c. 700 AD (Southern Netherlands)

A novel mathematical model describes spatial-temporal drug distribution within one or more brain units, which are cubic representations of a piece of brain tissue with brain capillaries at the edges.

Another research line is the development of a spatial CNS drug distribution model, by ultimately including the 3-dimensional anatomical organization of the CNS.

This research focuses on the distribution of chemical elements in protoplanetary disks, the birthplaces of planets. These disks form around young stars and contain gas and dust, from which planets grow. Ice plays a crucial role in planet formation, aiding the clumping of dust particles and influencing…

Over the last decades, income inequality has increased globally. How do social policies affect this increasing trend? How do international trade and technological progress affect inequality? What is the profile of income inequality in China?

The book 'Dutch Income (Re)Distribution, trends 1977-2019' was published on the 14th of October. Files related to the project can be downloaded via this website.

The LOFAR radio telescope produces petabytes of data every year. Radio Astronomers use complex multi-step pipelines to process this data and produce scientific images.

The skin barrier function is provided by the stratum corneum (SC). The lipids in the SC are composed of three lipid classes: ceramides (CERs), cholesterol (CHOL) and free fatty acids (FFAs) which form two crystalline lamellar structures. In the present study, we investigate the effect of CER chain length…

The objective of this study is to better understand the distribution of microplastics in the environment. More specifically, we will quantify the abundance and distribution of microplastics on beaches.

Mycorrhizas are symbiotic associations between soil fungi and most plant species.

DSE 2.0 concerns research on DSE techniques for complex dCPS

The project aims to explore Eurasian elk's role in the ecosystems of the past and its relationship with humans through analysis of its distribution and habitat in the Netherlands.

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

The stratum corneum (SC) plays a fundamental role in the barrier function of the skin. The SC consists of corneocytes embedded in a lipid matrix.

A practical checklist with legal, technical and ethical points of view will from now on guide the data scientists when working in Artificial Intelligence: the AI Impact Assessment (AIIA). It has been developed by ECP (Platform of the Information Society) and nine other partners, among them the Leiden…

Buitelaar argues that IOs micro-level discourse adapts imperfectly to macro-level changes, balancing adaptation to pressures with commitment to values.

On the 21st of June, Marieke Meelen succesfully defended her PhD-thesis and graduated. LUCL congratulates Marieke on this great result.

On the 30th of September Christine Ketel successfully defended a doctoral thesis and graduated.

Dynamical systems describe the evolution of objects in a space over time and may be used to model physical phenomena. Due to this, much research is dedicated to understanding the mathematics of dynamical systems.

Political scientist Leila Demarest tells about her research to Nigeria’s National Assembly. How do politicians cooperate and how are public resources distributed among the different regions?

The central research question focuses on identifying shifts in the urban social network in terms of private, semi-public and public space by means of mapping the spatial distributions of wells and cesspits in the town of Haarlem in the course of the pre-industrial period (1200-1800). Shifts may be indicative…

Leiden and Austrian researchers have succeeded in further uncovering how a plant cell passes on the growth hormone auxin in a directional manner to the next cell. Three proteins that cling together in a bunch appear to be essential for this important transport process. ‘This discovery solves a crucial…

On the 25th of September, Alzenir Mendes Martins de Menezes successfully defended a doctoral thesis. Leiden University Centre for Linguistics congratulates Alzenir on this achievement!

This article presents an evidence-based investigation of spontaneous hospitalization and distribution of patients after the Manchester terrorist attack.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

We present an extensive study of methods for exactly solving stochastic constraint (optimisation) problems (SCPs) in network analysis. These problems are prevalent in science, governance and industry.

Galaxies form and live inside dark matter haloes. As a consequence, they are exposed to the tidal fields generated by the surrounding matter distribution: this imprints a preferential direction to the galaxy shapes, which leads to a coherent alignment on physically close galaxies, called intrinsic a…

This thesis examines the link between simple molecules and the underlying structure and chemistry within protoplanetary disks - the birthplaces of planets.

Social assistance and minimum income benefits are important instruments as a safeguard against low income and poverty. There have been major developments in minimum income benefits both in developed and developing countries over the last decades. Our study collects several empirical studies regarding…
