OB associations are loose groups of young, massive stars. They constitute the last stage of the massive starformation process, and the context in which new stars are formed.

Stellar feedback is a crucial ingredient in the evolution of galaxies.

The Role and Effectiveness of the G20. In this article, published in The Changing Global Order part of the United Nations University Series on Regionalism book series, author Jaroslaw Kantorowicz discusses the evolution of the G20.

I have studied the hot, diffuse gas around and between galaxies. Specifically, I have used the EAGLE numerical simulations of galaxy formation to predict the properties of this gas, and I have used those properties to predict specific observables: soft X-ray absorption and emission lines.

The relative simplicity of the bacterial cell, short generation times and well defined and inexpensive culturing conditions have significantly contributed to our understanding of many complex biological systems. Yet the workings of the bacterial genome, seemingly impossibly compressed within a tiny…

Protein–protein complexes are formed via transient states called encounter complexes that greatly influence the formation of the stereospecific complex.

Following the Big Bang, structure in the Universe started collapsing under the force of gravity. This resulted in the formation of the first stars, galaxies and clusters of galaxies.

Organisms often need to adapt more efficiently and devise new strategies for surviving difficult ecological circumstances.

GLOBALINT is a pioneering study of intelligence in the Global South. It asks ‘how do (un)democratic shifts in political governance impact intelligence services in contexts of violent conflict?

English The purpose of this research is to identify and examine the challenges faced by African States in the field of foreign investment with a view to contribute not only to the academic debate, but also to foster awareness and develop the capacities of these States with regard to the drafting, negotiation…

Freshwater is an important resource, but at a great risk of species decline due to habitat loss, pollution and over-exploitation, and invasive alien species.

Understanding the formation and evolution of planetary systems is one of the most fundamental challenges in astronomy. To directly image and study young exoplanets and the circumstellar disks they form from, dedicated high-contrast imaging instruments are built.

This is special issue of the journal Language & Communication. The papers of this issue delve into the multifaceted realm of (non)belonging.

This thesis utilises the exceptional sensitivity and resolution of LOFAR to explore the low-frequency Universe, while simultaneously advancing the telescope's capabilities to enable new scientific discovery.

Nowadays, it is well known that hydrogen and helium (and small traces of lithium and beryllium) were created shortly after the Big Bang, while the heavier elements are created in the cores of stars at different evolutionary stages. When these stars explode as supernovae, they expel metals synthesised…

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

This book rovides an economic history of Portugal over the course of eight centuries, from 1143 through to 2010 and situates Portugal's economic growth within the context of European development. It also responds to fundamental questions about when, how and why the economy expanded, stagnated or co…

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.

Japan's Occupation of Java in the Second World War draws upon written and oral Japanese, Indonesian, Dutch and English-language sources to narrate the Japanese occupation of Java as a transnational intersection between two complex Asian societies, placing this narrative in a larger wartime context of…

Why do black holes emit thermal radiation? And how does a closed quantum system thermalize?

This book contextualizes the use of terror as part of wider movements of political contention, demonstrating that terroristic innovation occurs as part of wider historical processes rather than in a vacuum.

Multiple stars, that is two or more stars composing a gravitationally bound system, are common in the universe.

Can international organisations be held responsible for violations of international law by peacekeepers in a peacekeeping operation?

Besides the Hortus being a beautiful place where visitors can relax and learn more about plants, we also facilitate botanical research. At the botanic garden, our ‘Living Botany’ research group investigates (plant) biodiversity and the relationship between plants and people.

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…

Slavoj Žižek is one of the most prominent public intellectuals of the left. His central claim holds that “today, it is more crucial than ever to continue to question the very foundations of capitalism as a global system”.

This thesis investigates how quantum, quantum-inspired, and hybrid quantum-classical computation can enhance key points of the automated machine learning (AutoML) pipeline under the constraints of noisy intermediate-scale quantum (NISQ) devices.

The Copenhagen interpretation of quantum mechanics states that a measurement collapses a wavefunction onto an eigenstate of the corresponding measurement operator.
