One of the key quests in astronomy is to study the growth and evolution of galaxies across cosmic time. Radio observations provide a powerful means of studying the formation of stars and subsequent buildup of distant galaxies, in a way that is unbiased by the presence of dust.

The applications of studying the early development of insects range from agriculture to material science.

Phosphorylation affects all four major biomolecules – proteins, lipids, carbohydrates and nucleic acids – and plays a pivotal role in the most fundamental cellular functions.

The next generation of high-contrast imaging instruments on space-based observatories requires sophisticated wavefront sensing and control in addition to a high-performance coronagraph.

In this dissertation, the synthesis and characterization of a series of iron complexes based on different ligand platforms are described.

Antibiotic-resistant bacteria pose a major health threat. Addressing this challenge requires among others the development of new antibacterial compounds. The research described in this thesis focuses on discovering novel antibiotics from soil bacteria, specifically Streptomyces and Paenibacillus.Despite…

In 2018, the number of mobile phone users will reach about 4.9 billion. Assuming an average of 5 photos taken per day using the built-in cameras would result in about 9 trillion photos annually.

Growth hormone profiles are pulsatile and highly variable between individuals, limiting the implementation of mathemathical models to quantify an individual's secretion.

In this thesis, we present new laboratory data of interstellar dust analogues.

Understanding how galaxies form, interact, and evolve comes largely from comparing theory predictions with observational data. Numerical simulations of galaxies provide the most accurate approach to testing the theory, as they follow the non-linear evolution of gas and dark matter in great detail and…

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 elementary excitations of magnets are called spin waves, and their corresponding quasi-particles are known as magnons. The rapidly growing field of Magnonics aims at using them as information carriers in a new generation of electronic devices, (almost) free of electric currents.

In this thesis, I targeted the orchid genus Lepanthes, one of the six genera of angiosperms that surpasses 1,000 species in the Neotropics, as a study model to investigate the evolutionary processes that promoted species diversifications.

Streptomyces are prolific producers of enzymes and secondary metabolites, including more than 50% of all clinical antibiotics. This makes them highly attractive for medical, biotechnological, and industrial purposes.

With the dramatic growth of the image data on the web, there is an increasing demand of the algorithms capable of understanding the visual information automatically.

Optimization tasks in practice have multifaceted challenges as they are often black box, subject to multiple equality and inequality constraints and expensive to evaluate.

The formation and evolution of galaxies is fundamentally driven by the formation of new stars out of cold gas.

This thesis presents pioneering work on the panchromatic emission of some of the most luminous galaxies in the early Universe: star forming galaxies and active galactic nuclei.

In this PhD-thesis several new and existing data science application are described that are particularly focused on applications for tax administrations.

De afgelopen decennia verrasten terroristen regelmatig met onverwachte en spectaculaire aanvallen, zoals bijvoorbeeld de aanslag op het World Trade Centre in New York. Hoe kunnen de veiligheidsdiensten deze terroristen een stapje voor zijn? Ga eens te rade bij Charles Darwin en Steven Spielberg, adviseert…

Van steden die soms afwijken van het nationale buitenlandbeleid tot de directe invloed van geopolitiek op lokale ontwikkelingen: promovendus Pieter Jeroense, directeur van VNG International, onderzocht zeventig jaar internationalisering van Nederlandse gemeenten en zag opvallende ontwikkelingen.

Het was lastig om ambtenaren van de eerste Trump-administratie zover te krijgen te spreken over hun ervaringen op werk, maar het lukte socioloog Jaime Lee Kucinskas. Het beeld dat daaruit is ontstaan, is volgens haar niet al te best. ‘Hoe meer ik met ze sprak, hoe meer emoties ik zag. Ze waren ontzettend…
