We analyse the link between media consumption and the attitudes toward people living with HIV/AIDS in Chile. We used data from a sample of 1000 people, obtained in the 2011 wave of the World Values Survey (WVS). We use a logistic binary regression model by maximum likelihood. Our results suggest that…

In the traditional theory of linear elasticity, superposition dictates that the response of a material does not depend on the sequence of the applied mechanical actuations.

The class-imbalance problem is a challenging classification task and is frequently encountered in real-world applications. Various techniques have been developed to improve the imbalanced classification performance theoretically and practically.

Single-Molecule Microscopy (SMM) techniques constitute a group of powerful imaging tools that enable researchers to study the dynamic behavior of individual molecules.

Dissochaeta Blume (Melastomataceae, tribe Dissochaeteae) is well-known as a scrambling plant genus found in Southeast Asia, where it is an inhabitant of the tropical rainforests or evergreen forests.

The intracluster medium (ICM) is a hot, tenuous and X-ray emitting gas that pervades galaxy clusters.

The first direct detection of gravitational waves opened the possibility of mapping the Universe via this new and independent messenger.

Neuraminidases are enzymes that cleave glycosidic linkages of sialic acid. These enzymes are involved in influenza infections as well as in many cellular processes in mammals and micro-organisms.

This thesis deals with the use of sound in interactions in the context of participatory systems and data sonification. We investigate an interactive environment where participants perceive information of the data through sound elements.

This thesis has three main parts. The first part gives an algorithm to compute Hilbert modular polynomials for ordinary abelian varieties with maximal real multiplication. Hilbert modular polynomials of a given level b give a way of finding all of the abelian varieties that are b-isogeneous to any given…

This thesis is about cosmological inflation and its relation to observations.

The outbreaks of AIDS and COVID-19 showed clearly how infectious viruses can influence people’s lives. Investigating the changes in the host metabolism may provide a paradigm shift to consider immune-metabolic interactions as therapeutic targets.

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

My PhD research is devoted to studies of the conjectural cluster-algebraic symmetry in the theory of topological string, which is the simplest, however already non-trivial sector in the theory of string.

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.

Nicotinamide adenine dinucleotide (NAD+) is the substrate used for the introduction of the ubiquitous and highly dynamic PTM in which either one or multiple adenosine diphosphate ribose (ADPr) moieties are covalently attached to a nucleophilic side chain of an specific amino acid in the target protein…

Digitale en fysieke realiteiten vervloeien zich steeds meer met elkaar. Jelle van Buuren vertelt over de uitdagingen voor ordehandhaving bij Het Parool.

Met de komst van socialemediakanalen als Twitter, Facebook en Instagram is het makkelijker dan ooit om informatie met elkaar te delen. Ook desinformatie. Tijdens zijn promotie ontwikkelde informaticus Xueqin Chen een nieuwe manier om nepnieuws te herkennen en te voorspellen hoe berichten zich binnen…

Voor de tiende, en voorlopig laatste keer is een onderzoeksteam van de Universiteit Leiden aan het werk in het dorpje Horvat Kur, in het noorden van Israël. Negen studenten, drie onderzoekers en ’camp manager’ Josine Heijnen leggen hier onder leiding van hoogleraar Antiek Jodendom en Vroeg Christendom…

We are very excited to announce our Sustainability Series for 2023-2024. Each month an interactive workshop will be organised that discusses a specific theme of sustainability. Interested about sustainability? Do not hesitate to sign up to our events !

Het beëindigen van het zevenenveertig jarige lidmaatschap van het Verenigd Koninkrijk (VK) met de Europese Unie (EU) heeft de relaties tussen de twee fundamenteel veranderd. Na jaren van tumultueuze onderhandelingen bepaalt internationaal recht nu weer de VK’s relatie met de EU. Dit heeft geresulteerd…
