Elevated physical weathering exceeds chemical weathering of clays during the Paleocene-Eocene Thermal Maximum in the continental Bighorn Basin (Wyoming, USA)

Ji, Kaipeng (author), Wang, C. (author), Hong, Hanlie (author), Yin, Ke (author), Zhao, Chenlei (author), Prins, Maarten (author), Lourens, Lucas J. (author), Gingerich, Philip D. (author), Abels, H.A. (author)

The Paleocene-Eocene Thermal Maximum (PETM) global warming event at ∼56 million years before present changed catchment weathering and erosion. Increased chemical weathering of silicate minerals is thought to be an important process removing CO₂ from the atmosphere. However, changes in clay mineralogy can often be explained by...

Changed sediment composition prevents recovery of macrobenthic community four years after a shoreface nourishment at the Holland coast

Wijsman, Jeroen W.M. (author), Prins, Theo C. (author), Moons, J. J.Simeon (author), Herman, P.M.J. (author)

Sand nourishment is a widespread management strategy to protect sandy coasts against erosion. Nourishments can impact the benthic fauna directly by burial and indirectly by changing environmental conditions such as bottom shear stress and/or sediment composition (grain size distribution). The macrobenthic community in soft-bottom environments...

Comparative analysis of bore propagation over long distances using conventional linear and KdV-based nonlinear Fourier transform

Brühl, M. (author), Prins, Peter J. (author), Ujvary, Sebastian (author), Barranco, Ignacio (author), Wahls, S. (author), Liu, Philip L.-F. (author)

In this paper, we study the propagation of bores over a long distance. We employ experimental data as input for numerical simulations using COULWAVE. The experimental flume is extended numerically to an effective relative length of x/h=3000, which allows all far-field solitons to emerge from the undular bore in the simulation data. We apply the...

Reliable computation of the eigenvalues of the discrete KdV spectrum

Prins, Peter J. (author), Wahls, S. (author)

We propose a numerical algorithm that computes the eigenvalues of the Korteweg–de Vries equation (KdV) from sampled input data with vanishing boundary conditions. It can be used as part of the Non-linear Fourier Transform (NFT) for the KdV equation. The algorithm that we propose makes use of Sturm-Liouville (SL) oscillation theory to guaranty...

An accurate O(N^2) floating point algorithm for the Crum transform of the KdV equation

Prins, Peter J. (author), Wahls, S. (author)

We present an algorithm to compute the N-fold Crum transform (also known as the dressing method) for the Korteweg–de Vries equation (KdV) accurately in floating point arithmetic. This transform can be used to generate solutions of the KdV equation, e.g. as a part of the inverse Non-linear Fourier Transform. Crum transform algorithms that...

The Fine-Structure Constant as a Ruler for the Band-Edge Light Absorption Strength of Bulk and Quantum-Confined Semiconductors

Prins, P. Tim (author), Alimoradi Jazi, M. (author), Killilea, Niall A. (author), Evers, W.H. (author), Geiregat, Pieter (author), Heiss, Wolfgang (author), Houtepen, A.J. (author), Delerue, Christophe (author), Hens, Zeger (author), Vanmaekelbergh, Daniel (author)

Low-dimensional semiconductors have found numerous applications in optoelectronics. However, a quantitative comparison of the absorption strength of low-dimensional versus bulk semiconductors has remained elusive. Here, we report generality in the band-edge light absorptance of semiconductors, independent of their dimensions. First, we...

Circular economy and real estate: the legal (im)possibilities of operational lease

Ploeger, H.D. (author), Prins, M. (author), Straub, A. (author), Van den Brink, Robert (author)

Purpose: A paradigm in circular economy (CE) is that suppliers retain ownership of their products and materials, and that the users “only” pay for services. In many legal systems, however, elements incorporated in a building are considered to be fixtures, and therefore legally part of the building. This means that ensuring multi-cyclic...

Maximizing Authentic Learning and Real-World Problem-solving in Health Curricula Through Psychological Fidelity in a Game-Like Intervention: Development, Feasibility, and Pilot Studies

Kuipers, Derek A. (author), Terlouw, Gijs (author), Wartena, B.O. (author), Prins, Jelle T. (author), Pierie, Jean Pierrre E.N. (author)

High fidelity is regarded as a hallmark of educational games and simulations for health education. Mainly physical and functional fidelity are associated with authenticity, resulting in the pursuit of a true-to-life simulation and suggesting the imposition of a generally accepted and often unintentional design rationale that assumes that the...

Soliton phase shift calculation for the Korteweg–de Vries equation

Prins, Peter J. (author), Wahls, S. (author)

Several non-linear fluid mechanical processes, such as wave propagation in shallow water, are known to generate solitons: localized waves of translation. Solitons are often hidden in a wave packet at the beginning and only reveal themselves in the far-field. With a special signal processing technique known as the non-linear Fourier transform ...

A network approach to prioritize conservation efforts for migratory birds

Habitat loss can trigger migration network collapse by isolating migratory bird breeding grounds from nonbreeding grounds. Theoretically, habitat loss can have vastly different impacts depending on the site's importance within the migratory corridor. However, migration‐network connectivity and the impacts of site loss are not completely...

Fast nonlinear Fourier transform algorithms using higher order exponential integrators

Chimmalgi, S. (author), Prins, Peter J. (author), Wahls, S. (author)

The nonlinear Fourier transform (NFT) has recently gained significant attention in fiber optic communications and other engineering fields. Although several numerical algorithms for computing the NFT have been published, the design of highly accurate low-complexity algorithms remains a challenge. In this paper, we present new fast forward NFT...

Façade Leasing: Drivers and barriers to the delivery of integrated Façades-as-a-Service

Azcarate Aguerre, J.F. (author), Klein, T. (author), den Heijer, A.C. (author), Vrijhoef, R. (author), Ploeger, H.D. (author), Prins, M. (author)

The construction and renovation of the building envelope represents a significant fraction of a project’s life-cycle costs. It also has a determinant effect on the potential reduction in energy use, as well as on the improvement of the building’s indoor comfort. Nevertheless, the challenge of a low rate and depth in building energy renovations...

FNFT: A software library for computing nonlinear Fourier transforms

Wahls, S. (author), Chimmalgi, S. (author), Prins, Peter J. (author)

The conventional Fourier transform was originally developed in order to solve the heat equation, which is a standard example for a linear evolution equation. Nonlinear Fourier transforms (NFTs)1 are generalizations of the conventional Fourier transform that can be used to solve certain nonlinear evolution equations in a similar way (Ablowitz et...

The effect of hippocampal function, volume and connectivity on posterior cingulate cortex functioning during episodic memory fMRI in mild cognitive impairment

Objectives: Diminished function of the posterior cingulate cortex (PCC) is a typical finding in early Alzheimer’s disease (AD). It is hypothesized that in early stage AD, PCC functioning relates to or reflects hippocampal dysfunction or atrophy. The aim of this study was to examine the relationship between hippocampus function, volume and...

There is evidence for a beneficial effect of aerobic exercise on cognition, but underlying mechanisms are unclear. In this study, we test the hypothesis that aerobic exercise increases cerebral blood flow (CBF) in patients with vascular cognitive impairment (VCI). This study is a multicenter single-blind randomized controlled trial among 80...
