In this article, Samuels focuses on the active fostering of subjunctivity in processes of narrative worldmaking. Drawing extensively from the narrative of an HIV‐positive woman in Indonesia, she shows that by subjunctively leaving open multiple narrative trajectories and future possibilities, individuals…

Balsaminaceae is a diverse plant family characterized by a huge floral morphological diversity.

This thesis considers multi-prover commitment schemes whose security is based on restrictions on the communication between the provers.

This thesis describes the genetic and prokaryotic diversity of giant barrel sponges.

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

To address the fundamental questions of how life on Earth emerged and how common life may be in the Universe, it is crucial to know the chemical composition of the planet-forming material.

Inverse problems are problems where we want to estimate the values of certain parameters of a system given observations of the system. Such problems occur in several areas of science and engineering. Inverse problems are often ill-posed, which means that the observations of the system do not uniquely…

Shape and biological function are tightly connected. Physical descriptions are used to connect the shape of a biological system with its function.

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

Synthesis and application of chemical biology tools to study immunomodulatory signaling lipids.

Hydrodesulfurization (HDS) is an ubiquitous part of oil refining that ensures that fuels are cleaned of impurities and environment release of pollutants such as SOx and NOx gasses are minimized.

The effective treatment of tuberculosis (TB) remains a major challenge to global health.

Graphene nanoribbons (GNRs) are used as a current carrying substrate in investigation of current-induced forces in a low-temperature STM (chapter 2).

The application of nanomaterials in industrial processes and consumer products provides many societal benefits, but can also lead to the release of nanomaterials into the environment. The work in this dissertation aims to provide insights into the potential environmental impacts that may follow from…

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.

Errors are everywhere, and mechanical failures are especially common: buckled grain silos and cracked support columns are, justly, seen as an issue to be avoided.

This thesis focuses on amyloid proteins, a class of proteins that convert into amyloid fibrils.

Over the past years it has been discovered that the population of extra-solar planets is large and diverse.

CMLCA is a software tool that supports the technical steps of the Life Cycle Assessment. The focus of the program is on advanced computational aspects of life cycle inventory calculations.

The extensive use of electronic communication channels and other devices has opened new possibilities for collecting data on human behavior. This information is sometimes openly accessible, but largely part of administrative registration systems that are not open to the broader public. The data provides…

How can we broaden youth participation in STEM Learning

In deep reinforcement learning, searching and learning techniques are two important components. They can be used independently and in combination to deal with different problems in AI, and have achieved impressive results in game playing and robotics. These results have inspired research into artificial…

Plants are colonized by an astounding number of microorganisms that can provide different life-support functions, including nutrient acquisition and protection against (a)biotic stresses like drought or pathogen attack.

The key purpose of this project is to study tautological relations on the level of closed differential forms or even integral cochains (i.e. we don't take classes in cohomology).
