Geometry-based control of instability patterns in cellular soft matter

Janbaz, S. (author), Weinans, H. (author), Zadpoor, A.A. (author)

Recent research has shown the potential of rationally designed geometrical features for controlling the functionality of advanced materials. Of particular recent interest has been the use of geometry for controlling the buckling behaviour of soft materials under compression. However, the effects of geometry may be mixed with those of the...

Crossing Total Occlusions: Navigating Towards Recanalization

Sakes, A. (author), Regar, E. (author), Dankelman, J. (author), Breedveld, P. (author)

Chronic total occlusions (CTOs) represent the “last frontier” of percutaneous interventions. The main technical challenges lies in crossing the guidewire into the distal true lumen, which is primarily due to three problems: device buckling during initial puncture, inadequate visualization, and the inability to actively navigate through the CTO....

From big data to rich data: The key features of athlete wheelchair mobility performance

van der Slikke, R.M.A. (author), Berger, MAM (author), Bregman, DJJ (author), Veeger, H.E.J. (author)

Quantitative assessment of an athlete׳s individual wheelchair mobility performance is one prerequisite needed to evaluate game performance, improve wheelchair settings and optimize training routines. Inertial Measurement Unit (IMU) based methods can be used to perform such quantitative assessment, providing a large number of kinematic data. The...

Background: Suriname is a middle-income country with a multi-ethnic population. Urbanization and ethnicity may be associated with incidence of cerebrovascular disease, but so far this has not been documented for Suriname. The objective of this study was to examine the prevalence of stroke in the capital of Suriname, and its association with...

Anatomical parameters for musculoskeletal modeling of the hand and wrist

Mirakhorlo, M (author), Visser, J.M.A. (author), Goislard de Monsabert, B.A.A.X. (author), van der Helm, F.C.T. (author), Maas, H. (author), Veeger, H.E.J. (author)

A musculoskeletal model of the hand and wrist can provide valuable biomechanical and neurophysiological insights, relevant for clinicians and ergonomists. Currently, no consistent data-set exists comprising the full anatomy of these upper extremity parts. The aim of this study was to collect a complete anatomical data-set of the hand and wrist,...

Wireless instrumented klapskates for long-track speed skating

van der Kruk, E. (author), Den Braver (student), O. (author), Schwab, A.L. (author), van der Helm, F.C.T. (author), Veeger, H.E.J. (author)

In the current project, we aim to provide speed skaters with real-time feedback on how to improve their skating performance within an individual stroke. The elite skaters and their coaches wish for a system that determines the mechanical power per stroke. The push-off force of the skater is a crucial variable in this power determination. In...

Airway segmentation and centerline extraction from thoracic CT: Comparison of a new method to state of the art commercialized methods

Reynisson, P.J. (author), Scali, M. (author), Smistad, E. (author), Hofstad, E.F. (author), Leira, H.O. (author), Lindseth, F. (author), Nagelhus Hernes, T.A. (author), Amundsen, T. (author), Sorger, H. (author), Lango, T. (author)

Our motivation is increased bronchoscopic diagnostic yield and optimized preparation, for navigated bronchoscopy. In navigated bronchoscopy, virtual 3D airway visualization is often used to guide a bronchoscopic tool to peripheral lesions, synchronized with the real time video bronchoscopy. Visualization during navigated bronchoscopy, the...

A novel ultrasound technique for detection of osteochondral defects in the ankle joint: A parametric and feasibility study

Sarkalkan, N. (author), Loeve, A.J. (author), Van Dongen, K.W.A. (author), Tuijthof, G.J.M. (author), Zadpoor, A.A. (author)

(Osteo)chondral defects (OCDs) in the ankle are currently diagnosed with modalities that are not convenient to use in long-term follow-ups. Ultrasound (US) imaging, which is a cost-effective and non-invasive alternative, has limited ability to discriminate OCDs. We aim to develop a new diagnostic technique based on US wave propagation through...

Delays in admittance-controlled haptic devices make simulated masses feel heavier

Kuling, I.A. (author), Smeets, J.B.J. (author), Lammertse, P. (author), Onneweer, B. (author), Mugge, W. (author)

In an admittance-controlled haptic device, input forces are used to calculate the movement of the device. Although developers try to minimize delays, there will always be delays between the applied force and the corresponding movement in such systems, which might affect what the user of the device perceives. In this experiment we tested whether...

NeuroControl of movement: System identification approach for clinical benefit

Meskers, C.G.M. (author), De Groot, J. (author), De Vlugt, E. (author), Schouten, A.C. (author)

Progress in diagnosis and treatment of movement disorders after neurological diseases like stroke, cerebral palsy (CP), dystonia and at old age requires understanding of the altered capacity to adequately respond to physical obstacles in the environment. With posture and movement disorders, the control of muscles is hampered, resulting in...

Fast long-distance control of spin qubits by photon-assisted cotunneling

Stano, P. (author), Klinovaja, J. (author), Braakman, F.R. (author), Vandersypen, L.M.K. (author), Loss, D. (author)

We investigate theoretically the long-distance coupling and spin exchange in an array of quantum dot spin qubits in the presence of microwaves. We find that photon-assisted cotunneling is boosted at resonances between photon and energies of virtually occupied excited states and show how to make it spin selective. We identify configurations that...
