Retorica is overal. In de Tweede Kamer, in de rechtbank, en in de collegezaal; maar ook op de markt, op Twitter, en op Facebook. Mensen proberen elkaar steeds weer te overtuigen met argumenten, te verleiden met emoties, en te imponeren met een gunstige zelfpresentatie. De minor Retorica bestudeert de…

Voltammetry plays a crucial role in modern scientific research by offering valuable insights into the electrochemical properties of materials, with wide-ranging applications in fields such as materials science, energy storage, corrosion studies, and sensor development.

In this PhD study, I aim to deepen our understanding of the influence of major mycorrhizal types, namely arbuscular mycorrhizae (AM) and ectomycorrhizae (EM), on the global soil carbon cycle and their potential distribution changes under future environmental shifts.

Acute cardiovascular syndromes, including myocardial infarction or stroke, are the principal cause of death in the Western society. The main underlying pathology of cardiovascular diseases is atherosclerosis, which is caused by the accumulation of lipids and inflammatory cells in the vessel wall, in…

We find ourselves in an era of transition, not just towards a more computing- and data-driven society but also away from unsustainable fossil fuels as an energy source.

Leiden is een echte studentenstad met een sfeervol en compact centrum waar je alles vindt wat je in je studentenleven nodig hebt. Den Haag is een internationale studentenstad en biedt jou een mooie mix voor een rijk en gevarieerd studentenleven.

In some condensed matter systems, such as the surface of a 3D topological insulator, the electrons are effectively massless and we must necessarily use the massless Dirac equation to describe them.

Leiden is een echte studentenstad en heeft alles in huis om van jouw studententijd een onvergetelijke tijd te maken. En als internationaal georiënteerde studentenstad biedt Den Haag jou een mooie mix voor een geweldige studententijd.

Begin april trad Ton van Haaften aan als nieuwe Dean van de Honours Academy. Het is nu aan hem om de pioniersfase om te zetten in een consolidatiefase en het honoursonderwijs daarmee een standaardonderdeel van het Leidse onderwijsaanbod te maken. Nu zijn eerste maanden er op zitten, blikt hij vooruit…

The origin and evolution of galaxies are closely tied to the cyclic feedback processes between stars and the interstellar medium (ISM).

In recent decades, climate change has led to more frequent and severe drought events, causing serious consequences such as increased forest mortality and significant crop yield losses. Understanding how drought affects plants, especially economically important herbaceous species, is crucial for predicting…

Hot astrophysical plasma is ubiquitous in the Universe, from comets in our Solar system to the largest scale structures -- the cosmic web filaments. These hot plasmas, with the temperature of a few millions of degrees, are often observed in the X-ray wavelength range.

Catalysis is of extreme relevance in the production of everyday materials and plays a central role in many aspects of our life.

S.S. Kolipaka’s thesis questions and investigates the survival prospects of reintroduced tigers and their offspring’s in the human dominated landscape of Panna tiger reserve in India.

Indicators to measure progress in de-linking economic growth and environmental pressure.

Streptomyces are multicellular, Gram-positive bacteria in the phylum of actinobacteria which produce a high amount of bioactive natural products of which the expression is tightly coordinated with the life cycle.

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…

A sustainable resource management is an essential aspect to satisfy the current human needs without compromising the needs of future generations.

Machine Learning is becoming a more and more substantial technology for industry.

The electrochemical oxygen reduction reaction (ORR) is an essential half-reaction for the utilization of hydrogen as a sustainable fuel, via the conversion of hydrogen to electrons and protons facilitated by the ORR. In the most common fuel cells, the ORR is requires high loadings of non-abundant platinum…

The thesis addresses the long-term dynamical evolution of hierarchical multiple systems.

In this work, we investigate the minute circular dichroism effects of single nanoparticles.To this aim, we apply photothermal imaging with a polarization-modulated heating beam.

A modern ship design process is subject to a wide variety of constraints such as safety constraints, regulations, and physical constraints.

Large areas of space are filled by molecular clouds that consist of gas and dust grains that are the remnants of dead stars. When these clouds start collapsing, the decreasing temperature and increasing density cause gas particles to start accreting onto dust grain surfaces.

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

Soil is a home for an unbelievable diversity and abundance of microbial life that is essential for supporting life on our planet.

Plant exudates appeared long time ago in the history line of life in the early Devonian. They are typical saps produced by specialized cells.

During embryonic growth, cells proliferate, differentiate, and collectively migrate to form different tissues at the right position and time in the body.

Cholesterol influences many pathways, including serving as precursor for adrenal steroidogenesis. Imbalance of cholesterol levels has been implicated in several diseases including cardiovascular diseases and its underlying pathology, atherosclerosis.

Learning from small data sets in machine learning is a crucial challenge, especially when dealing with data imbalances and anomaly detection. This thesis delves into the challenges and methodologies of learning from small datasets in machine learning, with a particular focus on addressing data imbalances…
