This thesis addresses the chemical processes that determine the compositions of giant planet atmospheres.

Streptomyces are filamentous bacteria that produce more than two-thirds of known antibiotics.

The European Council and the European Commission have a similar role in agenda setting. Both place issues on the EU agenda. However, these institutions have distinct designs. They have different political attributes (the European Council has considerably more political authority) and information-processing…

This thesis describes the functional analysis of the Arabidopsis AHL15 gene.

Low-carbon (LE) technologies have a significant potential to reduce the total carbon emissions in China.

Despite being the object of intense study, embryonic development has been difficult to model due to a number of reasons. First, complex tissues can be comprised of many cell types, of which we probably only know a subset.

In populations with a seed-bank, individuals can temporarily become dormant and refrain from reproduction until they can become active again. The repository of all dormant individuals in the population is called the seed-bank. Seed-banks are observed in many taxa, including plants, bacteria and other…

Lees hier over geneeskunde docenten die middels de column 'Daarom Docent' laten zien wie zij zijn en wat ze doen in relatie tot onderzoek en lesgeven.

Nietzsches beroemdste en beruchtste boek Aldus sprak Zarathoestra is misschien het meest gelezen, maar waarschijnlijk ook het minst begrepen boek uit Nietzsches oeuvre. Zelf beschouwde hij het als zijn hoogtepunt. Hij noemde het een symfonie, een heilig boek, een vijfde evangelie en zelfs het grootste…

One of the key limitations of the direct imaging of exoplanets at small angular separations are quasi-static speckles that originate from evolving non-common path aberrations (NCPA) to which the primary adaptive optics system is inherently blind. The main focus of this thesis is the development and…

We study the interplay of topology and geometry with chirality for several passive and active systems, employing both analytical and numerical methods.

Pharmaceutical companies, governments and the general public have become increasingly aware that animal models used in drug testing lack vital aspects to serve as an accurate representation of human biology. As models of the human body should become more physiologically relevant, animal models no longer…

Circumstellar discs are the reservoirs of gas and dust that surround young stars and have the potential to become planetary systems.

The genetic information of all living organisms is contained in their DNA. Cells modify the degree of DNA compaction by epigenetics, which largely determines what genes are read out and which genes are transcriptionally silent.

De Universiteit Leiden gedenkt haar slachtoffers van de oorlog en eert alle leden van de universitaire gemeenschap die in verzet kwamen tegen onrecht. Zoals Rudolph Cleveringa, de rechtendecaan die in 1940 een protestrede uitsprak na het ontslag van Joodse collega's. Met historisch onderzoek, Cleveringalezingen…

In this thesis, we will utilize embryonic zebrafish tumour models to understand the interaction between engrafted human cancer cells and macrophages from the host, test drug administration modalities and anti-cancer efficacies of newly-developed PDT and PACT compounds, and test a light-triggered liposomal…

How can we, together international experts, define future needs of R+D contributions for innovations in the field of risk-based management of chemicals and products in a global perspective using alternative testing strategies to minimize animal tests?

Lees hier alles over de geschiedenis van de Universiteit Leiden, de oudste universiteit van Nederland. De Academia Lugduna Batava werd opgericht in 1575 en heeft als motto: Libertatis Praesidium ('Bolwerk van vrijheid').

In this Yearbook you will find some fascinating examples of what was done in 2021, not only by ourselves, but also by our international colleagues.

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…

The research described in this thesis has, using the zebrafish as a model system, shed new light on the intricate relationship between TB and DM2, in particular on the role of leptin, SHP-1 and glucocorticoids.

This project, South American population history revisited: multidisciplinary perspectives on the Upper Amazon (SAPPHIRE), investigates population dynamics in western South America on the basis of traces in the geographical, genetic, archaeological, ethnological, and linguistic record.

A recent study on reintroduced tigers in Panna Tiger Reserve in India reveals that risks from tigers increased more because of human behaviour and people's livestock husbandry practices.
