What political factors affect the speed or duration of EU legislative decision-making?

Understanding DNA repair mechanisms is essential for advancing plant biotechnology and crop improvement. This study investigates how double-strand breaks (DSBs), induced by CRISPR/Cas systems, are repaired in the model plant Arabidopsis thaliana, and how these processes influence Agrobacterium tumefaciens…

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.

The increasing competition in the automotive industry requires the tailored, swift development of technologically sophisticated vehicles. Therefore, the computationally expensive state-of-the-art simulation technologies are combined with optimization algorithms. An example of a real-world optimization…

Poly(lactic-co-glycolic acid) (PLGA) particles have been extensively studied as biodegradable delivery system to improve the potency and safety of protein-based vaccines. In this study we analyzed how the size of PLGA particles, and hence their ability to be engulfed by dendritic cells (DC), affects…

Artificial intelligence could help make the work of public sector organisations, professionals, policy- and decision makers more effective, more efficient, and ideally could make it more rationalised and evidence-based.

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

Organic amendments applied to agricultural fields can partially offset our carbon emissions to the atmosphere and improve the resilience of agriculture to the effects of climate change. Driving these benefits, however, are complex and poorly understood interactions between organic amendment properties,…

Cyber security is one of the critical challenges in our inter-connected world. Organizations are being constantly targeted by adversaries. Various critical systems become exposed on the Internet. Users can find that their data has been stolen from a company that they were not even aware of.

This article argues that opposition to government green investments is conditional on the method of financing.

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…

Reducing greenhouse gas emissions is one of the most pressing challenges that humanity faces in the coming decades.

This dissertation consists of two parts, each of which considers a different research area related to random interval maps. In the first part we are interested in random interval maps that are critically intermittent.

Urbanization brings benefits like housing and jobs but also challenges like biodiversity loss. CML's Urban research program uses science to create sustainable cities, focusing on the built environment (circular economy, urban mining) and enhancing urban nature for biodiversity and human benefits.

Metal-containing molecules combine geometrical features and a reactivity that are inherently different from that of organic molecules. My research focuses on light-activatable metal-based anticancer drugs and metal-functionalized liposomes. Light is a very selective way to activate photosensitive drugs…

Huub de Groot is professor in Biophysical Organic Chemistry. With his team he works in the field of photosynthesis and artificial photosynthesis. The molecular basis for photosynthesis is formed by protein complexes and organelles that contain chlorophyll molecules. The antenna systems herein capture…

Optimally solving real-world expensive Black-Box Optimization (BBO) problems w.r.t. real-world constraints, such as wall-clock time and computational costs, is extremely difficult and tedious.
