In this thesis, we examine various systems through the lens of several numerical methods.

The objective of this study was to investigate the expression and function of GRHL2 in different breast cancer subtypes.

In this thesis we will explore the use of fuzzy systems theory for applications in bioinformatics.

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

This summer, Leiden, The Hague, Noordwijk and Delft will be hosting the ‘Sizzling Summer of Space’. To tie in with the international Space Studies Programme, all kinds of activities on space exploration are being organised, from a film evening to a Science Café and an exhibition of satellites to the…

On Friday 24 March, Prof. Amanda Perry-Kessaris (Kent Law School) will deliver the monthly Leiden Socio-Legal Lecture.

On January 29th, the first annual event of the SUPER MoRRI project will be held in the Lipsius building in Leiden and will be thematically organized around engaging the public with research and innovation. Registration is free; hope to see you there!

Lecture, Tuesday Talks: Science Insights

Combining different disciplines, researchers work together to formulate innovative solutions to societal problems.

In this thesis, several aspects of software debugging from automated crash reproduction to bug report analysis and use of contracts have been studied.

To increase clinical success rate of drugs, a better understanding of drug action mechanism and disease dynamics is required. Metabolomics, which studies small molecules involved in biochemical processes in organisms, has shown to be a useful tool for this better understanding.

The first of the two volumes of this co-authored study has just been published by Metzler. The study explores the history of the concept ‘barbarism’ from the 18th century to the present and illuminates its foundational role in modern European and Western identity.

Exploring the largest structures in the universe by looking at the tiniest particles? Lydia Stofanova, PhD candidate at Leiden Observatory and SRON Netherlands Institute for Space Research, dives into this intricate connection. In her PhD research, she explored how elements like oxygen influence the…

From telescopes to science fiction: in just one semester, students with no background in physics or astronomy get to explore the universe. The first group of students started last month in the new minor Our Universe.

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

Despite being the second largest transmembrane protein family after GPCRs, the SLC superfamily has only gained significant attention in early drug development over the past decade.

Human vocal communication and music perception represent advanced cognitive skills, seemingly innate and universal. These faculties encompass a range of perceptual and cognitive abilities. Cross-species research sheds light on the origins of musicality by investigating whether these traits are shared…

As a contribution to the changing legislation and evolving societal attitudes concerning environmental issues, this project aims to enhance and manipulate the plants’ own natural defense mechanisms against western flower thrips (WFT).

Neurodegenerative diseases pose a large medical and societal challenge. The etiology of these diseases is still poorly understood, which makes drug discovery for these diseases difficult.

This special issue of the peer-reviewed journal Amsterdamer Beiträge zur älteren Germanistik (Brill, 2021) brings together articles that explore new digital ways of analyzing and annotating Old English vocabulary.

How do urban residents in Brazil and the Netherlands (The Hague and Leiden) perceive the cultural benefits of urban forests? How are these benefits spatially distributed across cities? How do socio-demographic factors shape these perceptions, and do these differences vary between countries?

Currently the focus of the project is the development of a tool that utilizes dimensionality reduction techniques in order to analyze and interpret the lexical and phonological variation between different sign languages. Additionally, the application of deep learning techniques for the extraction of…

Until the 1990s, the only known planets were those in our Solar System. Three decades later, several thousand exoplanets have been discovered orbiting stars other than the Sun, and substantial efforts have been made to explore these strange new worlds through spectroscopic analyses of their atmosphe…

In the search for sustainable energy solutions, the idea of artificial photosynthesis has been proposed as an approach with which to use water and sunlight to produce hydrogen.

In the era of big data, extracting insights from complex datasets is a key challenge. This thesis demonstrates the superiority of graph-based methods over traditional clustering (e.g., k-means, DBSCAN) and outlier detection for analyzing high-dimensional and noisy data.

A project to explore the configuration of different types of settlement and its role in the evolution of landscape, both in pre-Roman times and in the so-called Colonial landscape. We used several techniques of field survey, pottery classification and other non-invasive approaches to the archaeological…

Glycoside hydrolases (glycosidases/GHs) are widely abundant enzymes in all kingdoms of life and are important biocatalysts that catalyze the hydrolysis of glycosidic linkages in oligo/polysaccharides, glycoproteins and glycolipids with tremendous efficiency

This thesis investigates reactive interfaces in surface science across three domains: heterogeneous catalysis, environmental nanoplastics, and two-dimensional materials.

Is our musicality unique? To find out, the Bird Singalong Project brings together singing parrots from all over the world. Do you have a parrot that sings or whistles along to songs and would you like to help us? Sing up now!

How do lipases in Mycobacterium tuberculosis help the bacteria survive, and can we target them to create new antibiotics?

Learning analytics tracks students’ online learning activities in order to support their learning. But what if most of their learning takes place offline, out of sight of digital eyes?

The research project of Yannis Patoukas proposes to explore the different intersections between experimental rock music of the 1960s and 1970s and electroacoustic music, with regard to studio practices and production techniques and their creative possibilities.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

Microscopic insight on lipid-based nanomedicine in vivo remains limited to the perception of the knowledge that could be obtained: if we interpret only what we see, then we only believe to know. Although believing to know encapsulates an undefined amount of uncertainty in the exploration of lipid-based…

Brussels, the heart of European diplomacy, offered MSc International Relations and Diplomacy (MIRD) students a two-day opportunity to explore NATO and the European External Action Service (EEAS), gaining valuable insights into their roles in shaping EU foreign policy and global security.
