Applying Manifold Calculus To Totally Nonparallel Immersions
(2025)Manifold calculus provides a way to approximate functors from the open sets of a manifold to spaces by a tower of polynomial functors. In this thesis, we explain how this works in detail for the functor of embeddings, a ... -
The Presence and Development of the Liking Gap among Chinese Female and Male Adolescents
(2025)Abstract People tend to believe they like others more than the other likes them, a phenomenon known as the Liking Gap. This research focuses on its presence and development during adolescence. Given that the increase in ... -
Maternal feelings of anxiety and depression and the development of self-regulation in early childhood: The role of parental support
(2025)Many mothers of young children experience symptoms of anxiety and depression, which not only affect their own well-being, but can also influence their child’s development. Increasing evidence suggests that maternal distress ... -
Compulsive social media use and need for autonomy satisfaction in Dutch adolescents, mediated by self-concept clarity
(2025)This study examined whether compulsive social media use among Dutch adolescents was associated with the need for autonomy satisfaction and if self-concept clarity mediated this relationship. Based on Self-Determination ... -

To what extent do pinball experiences facilitate emotional self-disclosure in male children
(2025)There has been a recent sharp decline in young people’s mental health, and an increase in emotional problems among the youth. Good social relationships are crucial to cope with the challenges in life. And emotional ... -
An Agent-Based model for Physical Climate Risk, Insurance Claim Management, and its Impact on the Real Estate Market
(2025)Extreme weather events can cause significant damage to properties and infrastructure. One of the most impactful events is heavy rainfall, which can result in either fluvial or pluvial flooding, causing damages both inside ... -
Language Development Starts at Home: The Role of Parental Support and Siblings in Early Childhood Language Development
(2025)Early language development is critical for a child’s language and overall development. Strong language skills provide the foundation for communication, social interaction, learning and future academic success. Language ... -
Sterile neutrinos and neutrinoless double beta decay
(2025)This thesis investigates sterile neutrinos in neutrinoless double beta decay within the minimal extension of the Standard Model. After introducing neutrino mass generation and decay mechanisms, we implement active and ... -
Signatures of phase transition in binary neutron star mergers
(2025)Binary neutron star (BNS) mergers are a promising testing ground for warm highly dense states of matter. During a binary merger, densities are expected to easily exceed the nuclear saturation density. This invites the ... -
The Role of Matter Loops and Kinetic Mixing in Higgs Portal Inflation
(2025)Cosmological inflation has emerged as a cornerstone of modern cosmology because it elegantly accounts for the Universe’s large scale homogeneity, flatness and the nearly scale invariant spectrum of primordial fluctuations, ... -
Beyond the horizon
(2025)This paper investigates holographic reconstructions of black hole interiors. It begins by presenting the historical evolution of the black hole information paradox, highlighting the main challenges in achieving a coherent ... -
Cosmological Perturbations Induced by Ultralight Scalar Dark Matter: A Quantum Field Theoretic Perspective.
(2025)The inhomogeneities in the early universe grow during the matter-dominated era, eventually giving rise to the large-scale structures we observe today. This growth is primarily driven by dark matter, which, at the onset ... -
The influence of bioturbation on geochemical cycles at Blakeney salt marsh, Norfolk: an analysis using lipid biomarkers
(2025)A redox dichotomy is seen in the pond sediments of the salt marshes in East Anglia, Norfolk, U.K. At Blakeney salt marsh, ponds contain two sediment types: bioturbated sediments are iron-rich and contain burrowing organisms, ... -
Soliton solutions for the electron flow in graphene.
(2025)In the past decades, graphene is a material of great interest. Due to its purity, electrons can move through the lattice with very low resistance. Therefore the well known Navier Stokes equations can be applied to model ... -
Probabilistic Path Integrals in Quantum and Statistical Physics
(2025)In this thesis, we explore the mathematical techniques for rigorously constructing path integral measures in quantum mechanics, statistical field theory, and relativistic quantum field theory. We begin with the quantum ...
