In this research project Nizar Rohana analyzes and reflects on taqsīm recordings by two leading figures of ‘ūd playing who were pillars of modern Arabic music, namely the Egyptians Muḥammad al-Qaṣabjī (1898-1964) and Riyāḍ al-Sunbāṭī (1906-1981).

Cellular stress response pathways are activated upon exposure to chemicals and help organisms deal with various molecular dangers (e.g. oxidative stress). When these pathways become hyper-activated an adverse response takes place and cells die, which may lead to organism-level toxicity such as drug-induced…

In this thesis it is posed that the central object of preference discovery is a co-creative process in which the Other can be represented by a machine. It explores efficient methods to enhance introverted intuition using extraverted intuition's communication lines.

Multicellular giant algae Chara species have been widely used in physiological studies for decades.

We aim to gain a better understanding of the natural disease progression of ALS in order to improve clinical trial design and analysis and to support drug discovery and clinical development of new drugs.

What are the capabilities or limitations of traveling between islands and how does this reflect seasonal variation? Is it possible to show higher levels of connectivity between islands based on generated pathways between several sites on two separate islands?

How is inflammation in tuberculosis controlled by interplay between autophagy and inflammasome signalling?

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

In the first part, we introduce a new condition, called toric-additivity, on a family of abelian varieties degenerating to a semi-abelian scheme over a normal crossing divisor.

He’s a fast and animated speaker, which is only logical because Gerard van Westen is driving an express train. His destination? A virtual human, consisting of algorithms that predict what an administered substance will do in the body. The train is already a long way down the line and the pharmaceutical…

This thesis describes the use of the evolutionary approach in the study of language change, aiming to provide a better insight in the mechanisms that play a role in language change and to validate this approach in the field of language change.

Assessing the feasibility and legitimacy of the current model of global tax governance and the role of the OECD and EU in international tax law-making.

How can novel bioimaging technologies and vertebrate model species be used to gain a better understanding of early cellular behaviours with the ultimate goal to increase our understanding of human development and disease processes?

Chapter 1,contains the numerical verification of the Birch and Swinnerton-Dyer conjecture for hundreds of Jacobians of hyperelliptic curves of genus 2, 3, 4 and 5.

Fundamental understanding of molecular reactions on metal surfaces is important for improving heterogeneous catalysis.

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.

In this project, we aim to obtain a quantitative understanding of the role of the immune system in tumor regression, of the role of tumor cell heterogeneity in cancer growth and of tumor cell migration properties.

On 6 June 2019, Edward Donelan defended his thesis 'Regulatory Management Policies and a Universal Model for Public Policy Making, Legislative Drafting and Managing Stocks of Legislation'. The doctoral research was supervised by Prof. W.J.M. Voermans.

This project is a collaboration between Sanquin, LUMC and LIACS. It focuses on the development of meta-modelling methods and tools for the exchange, analysis, and publication of anonymised patient data. Measures are being constructed to evaluate both the level of privacy and the extent to which an anonymized…

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Clearance is the most important pharmacokinetic parameter for drug dose selection. Pharmacokinetic information is typically first available in the adult population, and in general only limited pharmacokinetic data are available in children when drugs enter into the market. It is therefore of the utmost…

The Repository from the Drug Disease Model Resources (DDMoRe) consortium provides a home to a collection of computational models of disease and drug action that have been used in pharmaceutical and/or academic research. This publically available open-access resource will make it easier for researchers…

We use zebrafish as a model organism to study human development and disease as well as animal welfare and environmental impact.

We are developing the conceptual framework, which is new to this taxonomic group, and evaluate the current state of the art with respect to all critical parameters and transfer functions for a fully developed Population Consequences of Acoustic Disturbance (PCAD) model.

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.

Simulation is a formal scientific method used to develop, compare and test hypotheses (models). In the last few decades the use of simulation has increased dramatically in virtually all scientific disciplines, but is still limited in archaeology due to the technological barrier – coding skills. Starting…

The availability of complete plant genome sequences together with the ever increasing amount of data on the molecular, cellular and physiological mechanisms of plant development require mathematical and computational models to obtain a complete overview of and generate new insights into the quantitative…

Electrical signals travel like a wave through our neural pathways. The mathematical models for these movements could not yet properly describe all the biological properties of the nerves. PhD student Willem Schouten-Straatman changed this by improving the existing models. ‘I hope that one day we will…

The kidneys play a major role in the elimination of drugs. In children, the exact age-related physiological changes underlying kidney function remain largely unknown.

The discussion on employability of higher education graduates has been around for several years, with more emphasis in the 21st century. Yet, universities are still challenged in the pursuit of providing work-ready graduates who can meet industry expectations.

When new features are being written into software code, errors can easily be made. This causes bugs, which leads to software appearing later and being more expensive. Michiel Helvensteijn, a PhD student from CWI and the Leiden Institute of Advanced Computer Science, studied how to prevent these kinds…

Matthijs van Leeuwen of the Leiden Institute of Advanced Computer Science develops methods to make computer models interactive. With interactive models, experts can combine information from raw data with their own knowledge to make predictions more accurate. 'In this way we hope to build models that…

Do medicines arrive in the right amount at the right spot in our brain? By making a model that depicts our brain in small 'brain blocks', Esmée Vendel tries to find an answer to this question. Her new, mathematical model predicts the concentration of medicines in the brain over time and space. Vendel…

The main objective of this thesis was to develop clinically relevant survival models for patients with high-grade soft tissue sarcoma of the extremities, in particular the development and validation of prediction models for use in clinical practice.

After 41 years, Meindert Danhof, Professor of Pharmacology, is leaving the Leiden Academic Centre for Drug Research on 31 March. A symposium in his honour, prior to his farewell lecture, will show what has been achieved in this period. Danhof takes a look back on his career.

Mechanical interactions between cells and their environment play an important role in many biological processes.

This study aims to make a practical contribution to a new understanding and use of 3D reconstructions, namely as ‘laboratories’ to test hypotheses and visualize, evaluate and discuss alternative interpretations.
