Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

Dr. Helen Pluut heeft een artikel gepubliceerd in het gerenommeerde tijdschrift Organizational Behavior and Human Decision Processes (OBHDP) in samenwerking met Remus Ilies (National University of Singapore), Petru Curşeu (Open Universiteit en Babeş-Bolyai University) en Yukun Liu (University of Western…

Before the large scale use of renewable energy sources can be implemented in our society, the storage of electrical energy needs to be tackled. Storage the energy as hydrogen via the reduction of protons is a good option.

Vinasse is a major by-product generated by the sugarcane biofuel industry. It is a source of microbes, nutrients and organic matter and often it is recycled as fertilizer.

AI wordt veel gebruikt in HR-processen, maar we weten nog weinig over de bijdrage van deze applicaties aan eerlijke en inclusieve beslissingen. Leids onderzoeker Carlotta Rigotti is betrokken bij BIAS, een groot consortiumonderzoeksproject om de rol van AI te verduidelijken én een nieuwe app voor HR-professionals…

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.

We explored the Universe using weak gravitational lensing, a phenomenon that occurs when light from distant galaxies is bent by the gravitational fields of closer cosmic objects, much like how a lens distorts light.

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.

Continuous optimization is never easy: the exact solution is always a luxury demand and the theory of it is not always analytical and elegant.

De onderzoeksgroep ‘Governance of Crises’ bestudeert verschijnselen, dynamiek en spelers als het gaat om crisisbeheersing. Het Crisis Research Center (CRC) van de Universiteit Leiden maakt deel uit van deze onderzoekgroep.

This dissertation focuses on developing new mathematical and statistical methods to properly represent time-varying covariates and model them within the context of time-to-event analysis.

In multi/many-core System-on-Chips (SoCs), the performance is almost linearly scaling with the number of processing elements.

Self-assembly is an abundant process in nature and is vital to many processes in living organisms.

Membrane fusion is a vital process in living organisms and is mediated by zipper-like proteins.

Tin electrodeposition applications have rapidly evolved in the past 25 years.

Drug development is a time- and resource-consuming process that starts with the discovery and validation of a (protein) target that contributes to pathogenesis or disease progression.

Radiography is an important technique to inspect objects, with applications in airports and hospitals. X-ray imaging is also essential in industry, for instance in food safety checks for the presence of foreign objects.
