Saravana Jothi, N. S. (author), Hunt, A. (author)Metamaterials are artificially structured materials and exhibit properties that are uncommon or non-existent in nature. Mechanical metamaterials show exotic mechanical properties, such as negative stiffness, vanishing shear modulus, or negative Poisson's ratio. These properties stem from the geometry and arrangement of the metamaterial unit...journal article 2022

Thorsen, R.Ø. (author), Hulleman, C.N. (author), Rieger, B. (author), Stallinga, S. (author)Combining orientation estimation with localization microscopy opens up the possibility to analyze the underlying orientation of biomolecules on the nanometer scale. Inspired by the recent improvement of the localization precision by shifting excitation patterns (MINFLUX, SIMFLUX), we have adapted the idea towards the modulation of excitation...journal article 2022

Guo, J. (author), Groeblacher, S. (author)The rapid development of high-Q<sub>M</sub> macroscopic mechanical resonators has enabled great advances in optomechanics. Further improvements could allow for quantum-limited or quantum-enhanced applications at ambient temperature. Some of the remaining challenges include the integration of high-Q<sub>M</sub> structures on a chip, while...journal article 2022

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...journal article 2022

Pols, C.F.J. (author), Dekkers, P.J.J.M. (author), de Vries, M.J. (author)Physics inquiry can be interpreted as the construction of a cogent argument in which students apply inquiry knowledge and knowledge of physics to the systematic collection of relevant, valid, and reliable data, creating optimal scientific support for a conclusion that answers the research question. In learning how to devise, conduct and evaluate...journal article 2022

Schaeken, Teun (author), Hoogerbrugge, L.A. (author), Verschuur, D.J. (author)The acoustic wave equation describes wave propagation directly from basic physical laws, even in heterogeneous acoustic media. When numerically simulating waves with the wave equation, contrasts in the medium parameters automatically generate all scattering effects. For some applications - such as propagation analysis or certain wave-equation...journal article 2022

Tielen, R.P.W.M. (author), Möller, M. (author), Vuik, Cornelis (author)The use of sequential time integration schemes becomes more and more the bottleneck within large-scale computations due to a stagnation of processor’s clock speeds. In this study, we combine the parallel-in-time Multigrid Reduction in Time method with a p-multigrid method to obtain a scalable solver specifically designed for Isogeometric...journal article 2022

Dutta, S. (author), Chen, Zhiyi (author), Kaiser, Elias (author), Malcolm Matamoros, Priscilla (author), Steeneken, P.G. (author), Verbiest, G.J. (author)Although it is well known that plants emit acoustic pulses under drought stress, the exact origin of the waveform of these ultrasound pulses has remained elusive. Here, we present evidence for a correlation between the characteristics of the waveform of these pulses and the dimensions of xylem conduits in plants. Using a model that relates the...journal article 2022

(author)Low-field MRI scanners are significantly less expensive than their high-field counterparts, which gives them the potential to make MRI technology more accessible all around the world. In general, images acquired using low-field MRI scanners tend to be of a relatively low resolution, as signal-to-noise ratios are lower. The aim of this work is...journal article 2022

De Vries, Laurens (author), Sanchez Jimenez, I.J. (author)Existing indicators of electricity system adequacy need to be supplemented with economic performance indicators. As power systems are decarbonized, energy storage technologies are being developed and demand is becoming more flexible. Reliability standards need to reflect the price elasticity of these sources of flexibility. During scarcity...journal article 2022

Pan, J. (author), Ferreira, Carlos (author), van Zuijlen, A.H. (author)This study investigates the implementation of the vortex particle method (VPM) with the goal of efficiently and accurately estimating the power performances and flow characteristics for a Savonius rotor. The accuracy and efficiency of simulation methods are critical for the reliable design of Savonius rotors. Among various approaches, VPM is...journal article 2022

Zhang, S. (author), Zhao, Xunyi (author), Wang, H. (author)Progress has been made in how to suppress epidemic spreading on temporal networks via blocking all contacts of targeted nodes or node pairs. In this work, we develop contact blocking strategies that remove a fraction of contacts from a temporal (time evolving) human contact network to mitigate the spread of a Susceptible-Infected-Recovered...journal article 2022

Kudina, O. (author)This paper explores the productive role that social network platforms such as Facebook, play in the practice of memory-making. While such platforms facilitate interaction across distance and time, they also solidify human self-expression and memory-making by systematically confronting the users with their digital past. By relying on the...journal article 2022

Saredi, E. (author), Sciacchitano, A. (author), Scarano, F. (author)The occurrence of data outliers in PIV measurements remains nowadays a problematic issue; their effective detection is relevant to the reliability of PIV experiments. This study proposes a novel approach to outliers detection from time-averaged three-dimensional PIV data. The principle is based on the agreement of the measured data to the...journal article 2022
