This thesis explores Breaking of Ensemble Equivalence (BEE) in random graph models by examining the spectral properties of adjacency matrices. The goal is to identify spectral characteristics that differentiate random graph ensembles, enhancing the understanding of complex network structures and beh…

Sewer pipes are an essential infrastructure in modern society and their proper operation is important for public health. To keep sewer pipes operational as much as possible, periodical inspections for defects are performed.

From 19 to 21 September 2018 the third annual conference of the Law and Development Research Network (LDRN) will take place at Leiden University. The theme of the conference will be 'Interfaces'.

In the research project ‘Furthering public leadership’ the Leiden Leadership Centre collaborates with several public organisations in order to obtain academic insights on public leadership and to develop leadership in practice. This allows for evidence-based development of public leadership and direct…

How did Google's computer programme AlphaGo become so powerful? On June 29, developer Aja Huang elaborated on this during a lecture in the Gorlaeus building.

The contributions in this volume seek to highlight the atypical features of the Hanse, and place them in a wider context of common roots, influences and parallel developments.

In this thesis we explore machine and deep learning approaches that address keychallenges in high dimensional problem areas and also in improving accuracy in wellknown problems. In high dimensional contexts, we have focused on computational fluid dynamics (CFD) simulations.

Stochastic resetting is simple enough to be approached analytically, yet modifies stochastic processes in a non-trivial way.

Mariana Gkliati participates as a PhD representative and member of the Steering Committee to the Netherlands Network for Human Rights Research (NNHRR), the development of the long-existing Netherlands School of Human Rights Research.

Decision makers are faced with dilemmas as result of the corona crisis. Dr. Jeroen Wolbers, Assistant Professor Crisis Governance at the Crisis Research Center explains the existing dilemmas and what makes the corona crisis unique when compared to other crises.

No less than 33 project received a Leiden Kiem grant in 2023. How did they fare? Olga Bogolyubova shares experiences from her project ‘Interdisciplinary Approaches to the Study of Safety and Danger in the Digital World’.

Complex Organic Molecules (COMs) have been detected in objects across different stages of stellar evolution.

Tracking early human behaviour through plant processing and -exploitation.

Plants and their pollinators form complex interaction networks. Within these networks, species differ widely in the number of species they interact with.

The Collective Experience of Empathic Data Systems (CEEDs) consortium developed novel integrated technologies that support experiencing, analysing and understanding of very large datasets.

Lecture

What socio-cultural transformations did indigenous communities in the Lesser Antilles undergo from the late precolonial to the early colonial period in response to Amerindian­ European-African cultural encounters? How did Amerindian populations realign themselves in response to the colonisation…

Five questions about PREPARE, the new research project funded by the EU and led by Joana Cook. Cook is Assistant Professor of Terrorism and Political Violence at the Institute of Security and Global Affairs and lead investigator on PREPARE.

Workshop

How can we promote more durable solutions to protracted refugee situations and which roles can connectivity and mobility of displaced people play to improve protection and resilience?

Classical statistical methods, such as p-values, are difficult for researchers to apply correctly. They for example do not allow drawing conclusions from a study early, or for extending a study with extra research groups that want to make their data available later.

The majority of scientists, from archaeologists through to zoologists, collect huge volumes of data. Their massive databases contain large amounts of information which is difficult for humans to filter. With a solid grounding in statistics, we can develop algorithms for analysing and identifying patterns…

A biographical approach to material cultural interactions between Caribbean communities and Europeans across the historical divide (AD 1000-1800)

A new type of tripodal squaramide-based supramolecular hydrogels is developed and studied.

If you are interested in studying stochastics, the following information will help you to choose the right path.

Mathematics forms the basis of many innovations in technology, the service industry and science, such as data analysis and coding, artificial intelligence, weather or climate change modelling or understanding molecular processes. The researchers from the Mathematical Institute (MI) are constantly developing…

Microbiome composition of the spermosphere and the rhizosphere of wild and modern bean accessions grown in an agricultural and a native soil from Colombia was characterized by metagenomics and cultivation-dependent approaches.

Research in the POD-group addresses all features of random phenomena – modelling, structuring, analysis, control, optimisation – and covers both fundamental and applied aspects.

Xander, student Public Administration, did an internship at the Marine Corps Training Centre. During his internship, he worked on automating the system of logistics requests. Now he is working as a working student for the training centre.
