Less than 1 in 10 drug candidates that enter phase 1 clinical trials actually gets approved for human use.

Decentralized plug and play systems for energy production are the future picture of our society. Artificial photosynthetic systems are used for this purpose.

To study how planetary systems come into existence we study much younger systems still in formation.

The global agri-food system plays a critical role in food security and environmental issues.

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,…

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…

SEAtrans: an interdisciplinary research project that aims at studying the dynamics and processes of transitions in society-nature interactions in Southeast Asian societies.

Politicologen Rebekah Tromble en Michael Meffert (Universiteit Leiden) analyseren waarom sommige media frames aanhouden, terwijl andere frames snel in de vergetelheid geraken. Zij ontwikkelen een methode die is ontleend aan event-history. De casus die Tromble en Meffert bekijken, is de verslaglegging…

As a virtually inexhaustible source, solar energy plays a major role in future global energy scenarios.

De onderzoeksgroep Business, Technology & Public Policy van de afdeling Bedrijfswetenschappen van Universiteit leiden houdt zich bezig met het onderzoeken van de dynamische wisselwerking tussen ‘nieuwe’ technologieën en de verschillende belanghebbenden die hiermee interacteren, waaronder consumenten,…

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.

HEPGAME is a research project that combines the world’s fastest computer algebra system for High Energy Physics equations, FORM, with insights from artificial intelligence. The name combines High Energy Physics and Games.

Immunotherapies for cancer are an emerging class of therapeutic strategies which aim to treat cancer via augmentation of the immune system.

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

Vitamin A or retinol is essential in embryonic development, the visual cycle and the immune system.

Het onderzoeksproject van Prof.Dr. Arjen Doelman ‘Adaptive Semi-Strong Ecosystem Dynamics’ is geselecteerd voor financiering als een van de 7 onderzoeksprojecten binnen het programma Mathematics of Planet Earth (MPE) van NWO.

This thesis contains results on the arithmetic and geometry of del Pezzo surfaces of degree 1.In Chapter 1 we give the necessary background, assuming the reader is familiar with algebraic geometry.

Het seminar op 30 november jl. over schijnconstructies en intra EU arbeidsmigranten trok veel belangstellenden en was een succes. Deze bijeenkomst werd georganiseerd vanuit het onderzoeksproject Solidarity under Strain (SOLID), onderdeel van de Research Focus Area 'Interaction between Legal Systems…

One of the effects of climate change is the phenomenon of desertification, a process that occurs in semi-arid and arid areas and causes land degradation as well as vegetation loss. Due to the lack of resources, vegetation self-organizes to sustain itself by forming large-scale spatial patterns.

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…

Glucocorticoids (GCs) are widely prescribed as anti-inflammatory drugs due to their well-established immunosuppressive effects.

Modeling and analysis of cyber-physical systems are still challenging. One reason is that cyber-physical systems involve many different parts (cyber or physical), of different nature (discrete or continuous), and in constant interaction via sensing and actuating.

A large diversity of exoplanetary systems has been found, but it is still unclear what drives this diversity.

Inspired by natural photosynthesis, perovskite-based photoelectrochemical (PEC) systems are being developed for artificial photosynthesis, aiming to enhance solar-to-hydrogen conversion for green energy.
