Integrated elastomer-based device for measuring the mechanics of adherent cell monolayers

Herbert Shea, Cristina Martin Olmos, Alexandre Poulin, Francesca Sorba

Cells in the body collectively sustain mechanical deformations in almost all physiological functions. From the morphogenesis stage, cells' ability to sustain stress is essential for the body's well-being. Several pathologies have been associated with abnor ...

Dynamics of fracturing saturated porous media and self-organization of rupture

Carlo Peruzzo, Enrico Milanese

Analytical solutions and a vast majority of numerical ones for fracture propagation in saturated porous media yield smooth behavior while experiments, field observations and a few numerical solutions reveal stepwise crack advancement and pressure oscillati ...

Spectral Purification of Microwave Signals with Disciplined Dissipative Kerr Solitons

Tobias Kippenberg, Hairun Guo, Erwan Guillaume Albert Lucas, Wenle Weng

Continuous-wave-driven Kerr nonlinear microresonators give rise to self-organization in terms of dissipative Kerr solitons, which constitute optical frequency combs that can be used to generate low-noise microwave signals. Here, by applying either amplitud ...

Brain-actuated functional electrical stimulation elicits lasting arm motor recovery after stroke

Hua Zhang, José del Rocio Millán Ruiz, Robert Leeb, Inaki Asier Iturrate Gil, Serafeim Perdikis, Andrea Biasiucci, Tiffany Corbet, Thomas Schmidlin, Dragana Viceic

Brain-computer interfaces (BCI) are used in stroke rehabilitation to translate brain signals into intended movements of the paralyzed limb. However, the efficacy and mechanisms of BCI-based therapies remain unclear. Here we show that BCI coupled to functio ...

Controlling motion artefact levels in MR images by suspending data acquisition during periods of head motion

Purpose: Head movements are a major source of MRI artefacts. Prospective motion correction techniques significantly improve data quality, but strong motion artefacts may remain in the data. We introduce a framework to suspend data acquisition during period ...

Compact laser-assisted tools for high-resolution additive manufacturing

Paul Delrot

Micro-additive manufacturing has become an enabling technology in biomedical research as it allows for instance creating functional microstructures or studying cellular interactions at the microscale. Among the various manufacturing techniques laser-actuat ...

All-optically induced quasi phase matching in SiN waveguides for second harmonic generation enhancement

Tobias Kippenberg, Camille Sophie Brès, Martin Hubert Peter Pfeiffer, Davide Grassani, Svyatoslav Kharitonov, Adrien Billat

We report more than 30dB second harmonic generation enhancement in SiN waveguide by all-optical writing of a persistent χ(2) grating. Phase matching peaks are observed for different writing wavelengths. ...
