Siskins, M. (author), Kurdi, S. (author), Lee, M. (author), Slotboom, Benjamin J.M. (author), Xing, Wenyu (author), Mañas-Valero, Samuel (author), Coronado, Eugenio (author), Jia, Shuang (author), Han, Wei (author), van der Sar, T. (author), van der Zant, H.S.J. (author), Steeneken, P.G. (author)

Two-dimensional magnetic materials with strong magnetostriction are attractive systems for realizing strain-tuning of the magnetization in spintronic and nanomagnetic devices. This requires an understanding of the magneto-mechanical coupling in these materials. In this work, we suspend thin Cr₂Ge₂Te₆ layers...

Evidence of regional sea-level rise acceleration for the North Sea

Steffelbauer, D.B. (author), Riva, R.E.M. (author), Timmermans, Jos (author), Kwakkel, J.H. (author), Bakker, M. (author)

Global mean sea-level rise (SLR) has accelerated since 1900 from less than 2 mm yr-1 during most of the century to more than 3 mm yr-1 since 1993. Decision-makers in coastal countries, however, require information on SLR at the regional scale, where detection of an acceleration in SLR is difficult, because the long-term sea-level signal is...

Efficient tactile encoding of object slippage

Willemet, L. (author), Huloux, Nicolas (author), Wiertlewski, M. (author)

When grasping objects, we rely on our sense of touch to adjust our grip and react against external perturbations. Less than 200 ms after an unexpected event, the sensorimotor system is able to process tactile information to deduce the frictional strength of the contact and to react accordingly. Given that roughly 1,300 afferents innervate the...

Origin of the fractional derivative and fractional non-Markovian continuous-time processes

Van Mieghem, P.F.A. (author)

A complex fractional derivative can be derived by formally extending the integer k in the kth derivative of a function, computed via Cauchy's integral, to complex α. This straightforward approach reveals fundamental problems due to inherent nonanalyticity. A consequence is that the complex fractional derivative is not uniquely defined. We...

Wind tunnel tests of a wing at all angles of attack

Ma, Z. (author), Smeur, E.J.J. (author), de Croon, G.C.H.E. (author)

Tailsitters have complex aerodynamics that make them hard to control throughout the entire flight envelope, especially at very high angle of attack (AoA) and reverse flow conditions. The development of controllers for these vehicles is hampered by the absence of publicly available data on forces and moments experienced in such conditions. In...

Core–shell structured gold nanoparticles as carrier for ¹⁶⁶Dy/¹⁶⁶Ho in vivo generator

Wang, R. (author), Ponsard, Bernard (author), Wolterbeek, H.T. (author), Denkova, A.G. (author)

Background: Radionuclide therapy (RNT) has become a very important treatment modality for cancer nowadays. Comparing with other cancer treatment options, sufficient efficacy could be achieved in RNT with lower toxicity. β⁻ emitters are frequently used in RNT due to the long tissue penetration depth of the β⁻ particles....

Eltager, M.A.M.E. (author), Abdelaal, T.R.M. (author), Mahfouz, A.M.E.T.A. (author), Reinders, M.J.T. (author)

Motivation: Single-cell multi-omics assays simultaneously measure different molecular features from the same cell. A key question is how to benefit from the complementary data available and perform cross-modal clustering of cells. Results: We propose Single-Cell Multi-omics Clustering (scMoC), an approach to identify cell clusters from data...

The Fluid Dynamic Basis for Actuator Disc and Rotor Theories: Revised Second Edition

van Kuik, G.A.M. (author)

The first rotor performance predictions were published by Joukowsky exactly 100 years ago. Although a century of research has expanded the knowledge of rotor aerodynamics enormously, and modern computer power and measurement techniques now enable detailed analyses that were previously out of reach, the concepts proposed by Froude, Betz,...

Advances in Maintenance of Ports and Waterways: Water Injection Dredging

Kirichek, Alex (author), Cronin, K (author), de Wit, Lynyrd (author), van Kessel, Thijs (author)

The main objective of this chapter is to demonstrate developments in port maintenance techniques that have been intensively tested in major European ports. As regular port maintenance is highly expensive, port authorities are considering alternative strategies. Water Injection Dredging (WID) can be one of the most efficient alternatives. Using...

VC@Scale: Scalable and high-performance variant calling on cluster environments

Ahmad, T. (author), Al-Ars, Z. (author), Hofstee, H.P. (author)

Background Recently many new deep learning–based variant-calling methods like DeepVariant have emerged as more accurate compared with conventional variant-calling algorithms such as GATK HaplotypeCaller, Sterlka2, and Freebayes albeit at higher computational costs. Therefore, there is a need for more scalable and higher performance workflows of...

What motivates stakeholders to engage in collaborative innovation in the infrastructure megaprojects?

Chen, Xiaoyan (author), He, Qinghua (author), Zhang, Xinyue (author), Cao, Tingting (author), Liu, Y. (author)

Collaborative innovation has become an innovation paradigm to improve innovation performance and firms’ economic output. However, there is relatively little research investigating stakeholders’ drivers for engaging in collaborative innovation and the relative importance of drivers in infrastructure megaprojects. This research aims to address...

Cooling photon-pressure circuits into the quantum regime

Corveira Rodrigues, I.C. (author), Bothner, D. (author), Steele, G.A. (author)

Quantum control of electromagnetic fields was initially established in the optical domain and has been advanced to lower frequencies in the gigahertz range during the past decades extending quantum photonics to broader frequency regimes. In standard cryogenic systems, however, thermal decoherence prevents access to the quantum regime for...

Fast and accurate spectral-estimation axial super-resolution optical coherence tomography

de Wit, J. (author), Angelopoulos, Kostas (author), Kalkman, J. (author), Glentis, George Othon (author)

Spectral-estimation OCT (SE-OCT) is a computational method to enhance the axial resolution beyond the traditional bandwidth limit. However, it has not yet been used widely due to its high computational load, dependency on user-optimized parameters, and inaccuracy in intensity reconstruction. In this study, we implement SE-OCT using a fast...
