Exploring High-Precision Non-Assembly Mechanisms: Design of a Vitrectome Mechanism for Eye Surgery

Lussenburg, K.M. (author), Scali, Marta (author), Stolk, Maarten (author), Robijns, D. (author), Sakes, A. (author), Breedveld, P. (author)

A vitrectome is a commonly used instrument in eye surgery, which is used to cut and aspirate the vitreous body out of the eye. The mechanism of the vitrectome consists of miniature components that need to be assembled by hand due to their size. Non-assembly 3D printing, in which fully functional mechanisms can be produced in a single production...

A Telecom Infrastructure Compatible Quantum Link Using NV-centers

Stolk, A.J. (author), van der Enden, K.L. (author), Röhsner, M. (author), te Raa, I. (author), Hagen, R.A.J. (author), Biemond, J.J.B. (author), Meskers, A.J.H. (author), Morits, J.P.J. (author), van Zwet, E.J. (author), Hanson, R. (author)

We show the latest progress towards establishing a solid-state, metropolitan quantum link, consisting of two remote Nitrogen Vacancy (NV)-centers and a central measurement station. The entanglement is generated by converting single emitted photons to the same frequency in the telecom L-band, guiding them to a central beamsplitter, where a joint...

Nocebo Hyperalgesia in Patients With Fibromyalgia and Healthy Controls: An Experimental Investigation of Conditioning and Extinction Processes at Baseline and 1-Month Follow-up

Karacaoglu, Merve (author), Peerdeman, Kaya J. (author), Numans, M.E. (author), Stolk, Martha R. (author), Meijer, Simone (author), Klinger, Regine (author), Veldhuijzen, Dieuwke S. (author), van Middendorp, Henriët (author), Evers, A.W.M. (author)

Nocebo effects are adverse treatment outcomes that are not ascribed to active treatment components. Potentially, their magnitude might be higher in patients with chronic pain compared to healthy controls since patients likely experience treatment failure more frequently. The current study investigated group differences in the induction and...

Experimental demonstration of entanglement delivery using a quantum network stack

Pompili, M. (author), Delle Donne, C. (author), te Raa, I. (author), van der Vecht, B. (author), Skrzypczyk, M.D. (author), Maciel Ferreira, G. (author), de Kluijver, L. (author), Stolk, A.J. (author), Hermans, S.L.N. (author), Pawełczak, Przemysław (author), Kozlowski, W. (author), Hanson, R. (author), Wehner, S.D.C. (author)

Scaling current quantum communication demonstrations to a large-scale quantum network will require not only advancements in quantum hardware capabilities, but also robust control of such devices to bridge the gap in user demand. Moreover, the abstraction of tasks and services offered by the quantum network should enable platform-independent...

(author), van Zwet, E.J. (author), Hanson, R. (author)

Entanglement distribution over quantum networks has the promise of realizing fundamentally new technologies. Entanglement between separated quantum processing nodes has been achieved on several experimental platforms in the past decade. To move toward metropolitan-scale quantum network test beds, the creation and transmission of...

A link layer protocol for quantum networks

Dahlberg, E.A. (author), Skrzypczyk, M.D. (author), Coopmans, T.J. (author), Wubben, L.C.J. (author), Rozpdek, Filip (author), Pompili, M. (author), Stolk, A.J. (author), Pawełczak, Przemysław (author), Knegjens, R.J. (author), de Oliveira Filho, J.A. (author), Hanson, R. (author), Wehner, S.D.C. (author)

Quantum communication brings radically new capabilities that are provably impossible to attain in any classical network. Here, we take the first step from a physics experiment to a quantum internet system. We propose a functional allocation of a quantum network stack, and construct the first physical and link layer protocols that turn ad-hoc...

The effect of particle size distribution on the bulk thermal conductivity of biomass pellets

Gilvari, H. (author), Eijssen, Dirk (author), IJzermans, Kasper (author), Stolk, Maarten (author), Homsma, Thom (author), de Jong, W. (author), Schott, D.L. (author)

The large-scale storage of biomass pellets is challenging due to health issues, material loss, and the risk of fire and explosions. The thermal conductivity is a material property which plays a key role in determining the self-heating properties of biomass. Meanwhile, understanding the thermal conductivity and the affecting factors help to...

Dynamics of an orthopaedic team: Insights to improve teamwork through a design thinking approach

Caprari, E. (author), Porsius, J.T. (author), D'Olivo, P. (author), Bloem, R.M. (author), Vehmeijer, S.B.W. (author), Stolk, N. (author), Melles, M. (author)

Supporting teamwork in healthcare is a way to foster both the quality and safety of care, and better working conditions for all the team members. Although increasing attention is paid to this topic on a general level, there is less knowledge about its unfolding in orthopaedic units and its translation to interventions. OBJECTIVE: To identify...

Een complex-cognitieve benadering van stedebouwkundig ontwerpen

Stolk, E. (author)

De motivatie voor dit proefschrift is ontstaan in de stedebouwkundige praktijk. Ten eerste vanuit een verbazing over de complexiteit van de opgaven waarvoor stedebouwkundigen wordt gesteld, en de manieren die ze in hun loopbaan ontwikkelen om met deze complexiteit om te gaan. Ten tweede vanuit een verbazing over de hoge mate van ongrijpbaarheid...

Degrees of sustainable location of railway stations: Integrating space syntax and node place value model on railway sations in the province of North Holland's strategic plan for 2010-2040

Van Nes, A. (author), Stolk, E. (author)

Mobility on rails is acknowledged to be one of the most sustainable means of transportation between cities and towns. Therefore, a railway station’s location in a built environment and its degree of accessibility is essential to reach as many travellers as possible. Even though there exist several writings on network cities and TOD principles...

Comparison of regional and gobal GRACE gravity field models at high latitudes

Gunter, B.C. (author), Wittwer, T. (author), Stolk, W. (author), Klees, R. (author), Ditmar, P. (author)

In this study we address the question of whether regional gravity field modeling techniques of GRACE data can offer improved resolution over traditional global spherical harmonic solutions. Earlier studies into large, equatorial river basins such as the Amazon, Zambezi and others showed no obvious distinction between regional and global...

Donnell, K.O. (author), Schober, S. (author), Stolk, M. (author), Marzocca, P. (author), De Breuker, R. (author), Abdalla, M. (author), Nicolini, E. (author), Gürdal, Z. (author)

This paper discusses modeling, simulations and experimental aspects of active aeroelastic control on aircraft wings by using Synthetic Jet Actuators (SJAs). SJAs, a particular class of zero-net mass-flux actuators, have shown very promising results in numerous aeronautical applications, such as boundary layer control and delay of flow separation...
