Chinese materia medica (CMM), comprising a diverse array of natural substances from plants, animals, and minerals, has been integral to Traditional Chinese Medicine (TCM) throughout history. This study investigates the dynamic evolution of CMM, noting shifts in species for improved therapeutic effects…

The largest genus within the Phyllanthaceae family is a group called Phyllanthus L. Recent studies have shown, that Phyllanthus is paraphyletic with the genera Glochidion, Breynia and Synostemon nested within it.

In this thesis, I studied the origin and evolution of the non-thermal radiation in merging galaxy clusters.

Galaxies form and evolve through close interaction with their surroundings. As a result, the heavy elements ('metals') that are synthesized in stars, are found both inside and outside galaxies.

In this thesis new methodologies are developed for the detection and systematic study of radio sources in the early universe. This allows us to gain a deeper understanding of the formation and evolution of galaxies, the activity of supermassive black holes, and the final phase transition of our universe:…

In this thesis, we consider various (electro)chemical phenomena at surfaces and nanoparticles and their underlying atomistic processes, which we studied using first-principles methods such as density functional theory.

The Sun and all the stars in the night sky reside in the Milky Way galaxy. In the at-rest reference frame of the Galaxy, typical stars travel with velocities of about 100-200 kilometres per second.

Drie projecten met Leidse onderzoekers ontvangen van NWO een subsidie voor de bouw of vernieuwing van grootschalige onderzoeksfaciliteiten. Zij gaan werken aan elektronenmicroscopie, een X-omics initiatief en een röntgentelescoop. De projecten maken deel uit van de Nationale Roadmap voor Grootschalige…

Public Administration is a major refereed journal publishing articles on public administration, public policy and public management.

This problem analysis raises the importance of a two interlinked questions: (1) what are important digital skills in the public sector? and (2) how well do different organizational and individual factors explain differences in skills levels?

In onze eenjarige masteropleiding leer je hoe je het dagelijks leven van kwetsbare groepen - zowel in Nederland als wereldwijd - kunt bestuderen, en hoe je ze binnen de complexe processen van sociale en globale ontwikkeling kunt plaatsen.

The coursework within the Science Communication and Society (SCS) specialisation prepares students for internships and a career in communication about science and health.

In this project of the Center for Public Values & Ethics (CPVE) ongoing research is conducted on the history of advice to Dutch central government by so-called State committees from 1814 to 2014. State committees have been installed by Dutch central government since 1814 to provide expert advice, research…

Culturele Antropologie en Ontwikkelingssociologie in Leiden staat bekend om haar internationaal georiënteerde expertise. Met een breed scala aan theoretische, methodologische en regionale onderwerpen, biedt de opleiding een sterk gefundeerd en verdiepend programma.

CONSENT (Consumer sentiment regarding privacy on user generated content services in the digital economy) is a research project funded by the European Union under the 7th Framework Programme. The question central to this research is whether recent changes to consumer and commercial practices developed…

Groeiende gezondheidsverschillen, toenemende zorgkosten, de vergrijzing en het tekort aan zorgpersoneel zijn slechts enkele voorbeelden van uitdagingen waar de gezondheidszorg voor staat, zowel in Nederland als daarbuiten. Deze vraagstukken overstijgen de grenzen van de medische sector en raken aan…

Wetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which…

Dit thematische gebied richt zich op uitdagingen voor, en innovaties rondom, democratie en burgerschap in het licht van hedendaagse wereldwijde transformaties. Gelieerde onderzoekers onderzoeken deze vragen op verschillende schaalniveaus (lokaal, nationaal, regionaal, wereldwijd) en vanuit verschillende…

Publicaties die verschijnen in het kader van het onderzoeksproject Zelfredzaamheid en sociale bescherming over de levenscyclus.

This research delves into a region of space known as the interstellar medium (ISM), which is essentially the area between the stars filled with gas and dust.

The bacterial cell wall is a nearly universal structure that offers protection and gives the cell its shape. However, environmental stressors, such as cell wall-targeting antibiotics and hyperosmotic conditions, can induce bacteria to shift to a wall-deficient state. It is unknown whether the lack of…

This thesis is about the study of hydrocarbons via infrared spectroscopy.

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

This ecological community has long been known to affect host biology, and their diverse roles have been further clarified in recent years following numerous studies of animal:microbiota interactions in diverse systems.

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

We investigate the buildup of galaxies from various vantage points. The first two chapters focus on the stellar content of galaxies, especially the distribution of stellar masses at birth and potential variations therein in various galactic environments.

In this thesis, we use low-frequency and high-frequency radio observations to address the following questions regarding quasars: is the radio loud/quiet quasar dichotomy real?

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.

In this thesis, the research focuses on the properties of dark matter and dark matter haloes and how they connect with the galaxies we can observe in the Universe.

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

The high velocity tail of the total velocity distribution of stars provides essential insight into fundamental properties of the Galaxy.

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.

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.

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…
