This dissertation presents new cryptographic protocols, which can be divided into two families.

The Standard Model (SM) of particle physics fails to explain several observed phenomena and is incomplete. In order to resolve this problem, one may extend the SM by adding new particles.

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

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…

This proposed research uses ego-documents from visual artists that were not intended for publication to reassess the scholarly debate on the demise of the Russian Avant-garde aesthetic in the twenties and early thirties of the 20th century.

Low-mass main-sequence stars like our Sun are continuous sources of outflowing hot magnetised plasma. In the case of the Sun, this is known as the solar wind, whereas for other stars they are called stellar winds.

There is concern about the threat that nanoplastics (NPs) may pose to both wildlife and humans. This thesis explores the mechanisms of toxicity of polystyrene nanoparticles (PS-NPs) in chicken embryo.

Marine sponges are important members of reef ecosystems, as they play ecological roles that are essential for the health of the reef.

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

Science is typically a patchwork of research contributions without much coordination. Especially in clinical trials, the follow-up studies that we do fail to be the most promising.

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

Natural resources often stretch across borders that separate modern nation states. This can create conflict and limit opportunities for regulated consumption of their goods and services, but also provide opportunities for joint multinational efforts that exceed single country capabilities.

One of the main challenges in the development of an effective anti-cancer vaccine is the generation of an adequate and directed cellular immune response.

Streptomyces are bacteria abundant in soil that participate in diverse and complex interactions. These bacteria are the main producers of the antibiotics we currently use in the clinic.

Technologies that help to enhance our educational environments can be found everywhere.

In today's volatile market environments, companies must be able to continuously innovate. In this context, innovation does not only refer to the development of new products or business models but often also affects the entire organization, which has to transform its structures, processes, and ways of…

Human language is constantly evolving with its linguistic structure being shaped by language users at both individual and population levels. Focusing on the interplay between processes of language acquisition and communicative need in shaping human languages, this thesis introduces a novel computational…

Met de verkiezingen in aantocht doen politici regelmatig gewaagde uitspraken voor electoraal gewin. Leidse journalistiekstudenten checken in hoeverre die beweringen kloppen.

De onderzoeksgroep Cyber Security Governance bestudeert de impact van moderne technologie op governance, soevereiniteit, wetshandhaving en internationale betrekkingen, en levert toonaangevend academisch onderzoek en beleidsinzichten.

Climate change is a challenge for both current and future generations. New biological resources have to be developed in order to meet the demand for energy as well as the demand for food.

In this project of the Center for Public Values & Ethics (CPVE) ongoing research is conducted on the history of advice to Dutch central government by so-called State committees from 1814 to 2014. State committees have been installed by Dutch central government since 1814 to provide expert advice, research…
