Model-based impurity emission front control using deuterium fueling and nitrogen seeding in TCV (vol 63, 026006, 2023)

Basil Duval, Christian Gabriel Theiler, Cristian Galperti, Artur Perek

In the published paper titled 'Model-based impurity emission front control using deuterium fueling and nitrogen seeding in TCV' (2023 Nucl. Fusion 63 026006), the legend of figure 5 shows the wrong colors: red and blue are switched. This corrigendum provid ...

Green processing and biotechnological potential of grape pomace: Current trends and opportunities for sustainable biorefinery

Edgard Gnansounou, Ranjna Sirohi

Grape pomace is a high quality biodegradable residue of the winery industry. It is comprised of grape seed, skin and stalks, and is blessed with substantial quantities of phenols, flavonoids and anthocyanins with high antioxidant potential. Currently, ther ...

Retina Color-Opponency Based Pursuit Implemented Through Spiking Neural Networks in the Neurorobotics Platform

Marc-Oliver Gewaltig, Egidio Falotico, Lorenzo Vannucci, Paul Levi, Georg Hinkel, Stefan Ulbrich, Alessandro Ambrosano, Ugo Albanese, Murat Kirtay

The 'red-green' pathway of the retina is classically recognized as one of the retinal mechanisms allowing humans to gather color information from light, by combining information from L-cones and M-cones in an opponent way. The precise retinal circuitry tha ...

Imaging Photoplethysmography: What are the Best Locations on the Face to Estimate Heart Rate?

Jean-Marc Vesin, Sibylle Fallet, Fabian Braun, Virginie Moser

The potential of imaging photoplethysmography for cardiovascular monitoring applications has been demonstrated recently. Various processing schemes have been proposed to extract heart rate (HR) from a defined region of interest (ROI) on the face. However, ...

What is the Space of Spectral Sensitivity Functions for Digital Color Cameras?

Sabine Süsstrunk

Camera spectral sensitivity functions relate scene radiance with captured RGB triplets. They are important for many computer vision tasks that use color information, such as multispectral imaging, color rendering, and color constancy. In this paper, we aim ...

It has long been known that colored images may elicit afterimages in complementary colors. We have already shown (Van Lier, Vergeer, & Anstis, 2009) that one and the same adapting image may result in different afterimage colors, depending on the test conto ...

Care. Emerging Natures

Pieter Versteegh

The work addresses research by design as a subject and a method. It explores theorizations, experimentations, and verifications, all of them engaged in writing, drawing and building. It is discovery-led, and starts from a blurry "state of the arts". It osc ...
