Systems are called real-time systems, if the correctness of the system does not only depend on the correctness of the system output but also on whether the output is delivered on time.

Onderzoek aan de Leiden University College (LUC) past in het overkoepelende kader van mondiale uitdagingen die ook centraal staan in het onderwijs van LUC. Hierin passen belangrijke maatschappelijke thema’s zoals Vrede en Recht, Diversiteit, Welvaart en Duurzaamheid.

Stars like the sun are born in large molecular clouds existing from gas and dust. During the formation process, the chemical composition of the material can be altered drastically by the changing physical conditions.

In this thesis, we have studied the potential of the zebrafish larval model in studying the ECS, as a complementary model to the existing rodent models.

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

This PhD research sets out to unravel and explain the socio-structural and cultural impacts of oil-industrialization on the local Bakhtiari community in general and the industrial laborers it provided in specific.

Hydrogen fuel cells are expected to be pivotal in the energetic transition towards renewable energy sources such as solar and wind power. However, their industrial scalability is severely hindered by the high cost and degradation rate of platinum catalysts, one of their key components. Addressing this…

This thesis focuses on important life history traits and their trade-offs using two hexapod models. Particularly, the trade-off between immune defense and embryonic developmental speed is a central theme of this study.

Bio-energie met koolstofafvang en -opslag is een veelbelovende methode om CO2 uit de atmosfeer te halen en tegelijkertijd energie op te wekken. Maar deze methode is controversieel, omdat er veel grond en water voor nodig is.

De herkomst van Surinaamse rijst, een digitale tweeling van de aarde en een groot big-data project aan de Chileense hemel: drie Leidse wetenschappers ontvangen een ENW-KLEIN subsidie voor vernieuwend, fundamenteel onderzoek.

Energie winnen uit zonlicht en water: dát zou een oplossing zijn voor ons grootste milieuprobleem. Elektrochemicus Marc Koper onderzoekt de basis voor een CO2-neutrale toekomst. Over zijn werk staat nu een dossier online.

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

This thesis studied in depth the energy use and CO2 emissions of the industrial sector in China.

The molecular mechanisms that instigate a healthy cell to become malignant are fueled by (epi)genetic alterations in so-called driver genes.

The progressive loss and degeneration of dopaminergic neurons is a major pathological hallmark of Parkinson's disease (PD). The onset and progression of PD can be triggered by multiple risk factors, for instance, genetic mutation, environmental exposure, and aging.

Cathodic corrosion is a relatively unknown phenomenon that can severely etch metallic electrodes at cathodic (negative) potentials.

There is an increasing amount of attention on EU and its Member States contributions to implementation of two landmark agreements: the Paris Climate Agreement and the UN Agenda 2030 with Sustainable Development Goals (SDGs). Absent from the current literature is an analysis of the political effect of…

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.

In this thesis, I focused on studying the above- and belowground interactions of J. vulgaris from a plant-soil feedback (hereafter, PSF) perspective. I investigated the temporal variation of negative PSF and examined the effects of root-associated bacteria on plant performance and aboveground herbiv…

There are many interpretations of quantum mechanics, and ultimately experiments are needed to verify or falsify these interpretations.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…
