Euclid: Cosmology forecasts from the void-galaxy cross-correlation function with reconstruction
Frédéric Courbin, Georges Meylan, Yi Wang, Richard Massey
We have investigated the cosmological constraints that can be expected from measurement of the cross-correlation of galaxies with cosmic voids identified in the Euclid spectroscopic survey, which will include spectroscopic information for tens of millions ...
EDP SCIENCES S A2023Euclid : Effects of sample covariance on the number counts of galaxy clusters
Georges Meylan, Yi Wang, Richard Massey
Aims. We investigate the contribution of shot-noise and sample variance to uncertainties in the cosmological parameter constraints inferred from cluster number counts, in the context of the Euclid survey. Methods. By analysing 1000 Euclid-like light cones, ...
EDP SCIENCES S A2021Experimental Observation of Topological Fano Resonances for Audible Sound
Romain Christophe Rémy Fleury, Farzad Zangeneh Nejad
The Fano resonance is a widespread wave scattering phenomenon observed in many different systems, from cold atom physics, to electromagnetics, electronic circuits, and acoustics. It is characterized by a very sharp and asymmetric scattering cross-section s ...
2019Decoding the Grasping Intention from Electromyography during Reaching Motions
Aude Billard, Iason Batzianoulis, Nili Eliana Krausz
Background: Active upper-limb prostheses are used to restore important hand functionalities, such as grasping. In conventional approaches, a pattern recognition system is trained over a number of static grasping gestures. However, training a classifier in ...
2018Experimental demonstration of ray-rotation sheets
We have built microstructured sheets that rotate, on transmission, the direction of light rays by an arbitrary, but fixed, angle around the sheet normal. These ray-rotation sheets comprise two pairs of confocal lenticular arrays. In addition to rotating th ...
2018Gaze and discomfort glare, Part 1: Development of a gaze-driven photometry
Marilyne Andersen, Jan Wienold, Mandana Sarey Khanie
Discomfort glare is a major challenge for the design of workplaces. The existing metrics for discomfort glare prediction share the limitation that they do not take gaze direction into account. In order to overcome this limitation, we developed a ‘gaze-driv ...
2017Gauging nonrelativistic field theories using the coset construction
Alexander Monin, Georgios Karananas
We discuss how nonrelativistic spacetime symmetries can be gauged in the context of the coset construction. We consider theories invariant under the centrally extended Galilei algebra as well as the Lifshitz one, and we investigate under what conditions th ...
Amer Physical Soc2016Learning Reach-to-Grasp Motions From Human Demonstrations
Reaching over to grasp an item is arguably the most commonly used motor skill by humans. Even under sudden perturbations, humans seem to react rapidly and adapt their motion to guarantee success. Despite the apparent ease and frequency with which we use th ...
EPFL2014Simple and easily controllable parabolic-shaped microlenses printed on polymeric mesas
Jürgen Brugger, Cristina Martin Olmos, Joo Yeon Kim
A simple and easy shape-controllable approach is demonstrated for the fabrication of parabolic-shaped polymer microlenses (mu-lenses), which are widely used in bio-imaging systems such as microfluidic and lab-on-a-chip systems for improving the image quali ...
Royal Soc Chemistry2013Barrier effects in non-retinotopic feature attribution
When objects move in the environment, their retinal images can undergo drastic changes and features of different objects can be inter-mixed in the retinal image. Notwithstanding these changes and ambiguities, the visual system is capable of establishing co ...
