To an algebraic curve C over the complex numbers one can associate a non-negative integer g, the genus, as a measure of its complexity.

With the energy transition toward a renewable energy supply and a CO2-neutral economy, electrification of the energy system is rising in importance, which leads to the challenge of long-term storage of renewable electricity.

The aim of this project was to estimate emissions from lead products-in-use for the past, the present and the future and assess the development of toxicological risks associated with these products.

The ongoing increase in antimicrobial resistance combined with the low discovery of novel antibiotics is a serious threat to our health care.

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

Multi-objective evolutionary computation aims to find high quality (Pareto optimal) solutions that represent the trade-off between multiple objectives.

To limit the effects of climate change, global average temperature since pre-industrial measurements are to be kept well below 2 °C preferably even at 1.5 °C.

The experiments described in this thesis employ local lentiviral knockdowns in brain areas of female zebra finches followed by behavioural assays consisting of preference and Go/Nogo tasks.

In analogy to mathematical proofs, the goal of a proof system is for a prover to convince a verifier of the correctness of a claim.

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

This research delves into the unique cultural approach of the Tenggerese people, an Indigenous community in East Java, Indonesia, regarding elderly care. It focuses on their traditional practices of bakti (‘filial piety’) and sayan (‘mutual aid’), deeply ingrained in the community's lifestyle and va…

A management strategy has been developed for field margins to reduce pesticide drift to non-target areas and to promote biodiversity on arable land. To this end, 3 and 6 m wide strips along the edges of winter wheat, sugar beet and potato crops have been left unsprayed with herbicides and insecticides…

Op 11 juni 2020 verdedigde Sabine Witting haar proefschrift 'Child Sexual Abuse in the Digital Era: Rethinking Legal Frameworks and Transnational Law Enforcement Collaboration'. Het promotieonderzoek is begeleid door promotoren prof.mr. J.J. Sloth-Nielsen en prof.dr.mr. S. van der Hof.

Possible improvements for the assessment of abiotic depletion in LCA.

In the thesis the dynamics of strategies is studied from two perspectives.In the first part of the thesis strategies are considered to be opinions present in a community.

Interactive exploration of large volumes of data is increasingly common, as data scientists attempt to extract interesting information from large opaque data sets. This scenario presents a difficult challenge for traditional database systems, as (1) nothing is known about the query workload in advance,…

As a non-invasive genetic method, eDNA based approaches have become an important component of ecologists' and environmental managers' toolkits for biomonitoring in conservation and an increasingly important source of ecological knowledge.

In my research, we developed a method to distinguish knots. A knot is a mathematical depiction of the everyday knot that occurs in ropes and cords.

It is an established fact that the Standard Model has to be extended to explain the so-called Beyond the Standard Model (BSM) phenomena: dark matter, matter-antimatter asymmetry of the Universe and neutrino flavour oscillations.

In-use stocks of products can be considered as intermediaries between human needs and the physical world.

Time-series forecasting through modelling sequences of temporally dependent observations has many industrial and scientific applications. While machine learning models have been widely used to create time-series forecasting models, creating efficient and performant time-series forecasting models is…

Prof. Herman P. Spaink heeft een subsidie gekregen om te screenen voor nieuwe geneesmiddelen tegen tuberculose. Deze subsidie voor de verdere ontwikkeling van robottechnologie voor grootschalige geneesmiddelenscreening was mogelijk dankzij donaties van Leidse alumni.

Hoe kun de betrouwbaarheid en bruikbaarheid van het gevonden materiaal beoordelen?

Leidse onderzoekers hebben de DNA volgorde van de Europese paling bepaald. Kennis van de genetische code van deze primitieve vissoort is belangrijk om de soort te kunnen beschermen tegen uitsterven maar ook ten behoeve van visserij en aquacultuur. De gegevens zijn nu gepubliceerd in het vrij toegankelijke…

Dr. Annemarie H. Meijer van het Instituut Biologie Leiden gaat een nieuw Marie Curie trainingsnetwerk coördineren dat 3,7 miljoen subsidie ontvangt van de Europese Commissie. Het vierjarige project begint in januari 2012 en heet: “FishForPharma: Training Network on Zebrafish Infection Models for Pharmaceutical…

Het Antoni van Leeuwenhoek/Nederlands Kanker Instituut, het Leids Instituut voor de Chemie en het Pivot Park Screening Centre gaan kennis en infrastructuur delen in het Cancer Drug Discovery Initiative. Vrijdag 11 oktober tekenden ze een letter of intent.

Jelle van Buuren bespreekt bij Nieuwsuur hoe Syrische oorlogsmisdadigers in Nederland terecht kunnen komen.

Eén op de vijf Syrische vluchtelingen die via de Turkije-deal naar Nederland wil komen, mag ons land niet in. Er blijkt te worden gescreend op de denkbeelden van die vluchtelingen. Ondanks dat het geen nieuwe ontwikkeling is, is het toetsten op deze wijze officieel niet toegestaan, zo zegt hoogleraar…
