Dynamics and potential drivers of CO2 concentration and evasion across temporal scales in high-alpine streams

Tom Ian Battin, Asa Lovisa Viktoria Horgby, Nicolas Thomas Georges Escoffier, Luis Gómez Gener

Carbon dioxide (CO2) evasion from streams greatly contributes to global carbon fluxes. Despite this, the temporal dynamics of CO2 and its drivers remain poorly understood to date. This is particularly true for high-altitude streams. Using high-resolution t ...

Fast high-resolution brain metabolite mapping on a clinical 3T MRI by accelerated H-1-FID-MRSI and low-rank constrained reconstruction

Dimitri Nestor Alice Van De Ville, Michel Kocher, Matthieu Guerquin-Kern, Jeffrey Adam Kasten, François Lazeyras, Sébastien Courvoisier

Purpose: Epitomizing the advantages of ultra short echo time and no chemical shift displacement error, high-resolution-free induction decay magnetic resonance spectroscopic imaging (FID-MRSI) sequences have proven to be highly effective in providing unbias ...

On Problem Formulation, Efficient Modeling and Deep Neural Networks for High-Quality Ultrasound Imaging

Jean-Philippe Thiran, Dimitris Perdios, Marcel Arditi, Adrien Besson, Florian Martinez, Manuel Vonlanthen

Recently, many pulse-echo ultrasound (US) imaging methods have relied on the transmission of unfocused wavefronts. Such a strategy allows for very high frame rates at the cost of a degraded image quality. In this work, we present a regularized inverse prob ...

Crowd Dynamics in Small Teams in Higher Education

Christopher Tucci, Gianluigi Viscusi

This article aims to empirically study “crowd” dynamics in small teams and complement the work presented in Tucci et al. [2016], and Tucci and Viscusi [2017]. As in previous papers, we use as theoretical lens the framework and related typology of “crowd” d ...

Quality assessment of an HDR dual-layer backward-compatible codec compared to uncompromised SDR and HDR solutions

Touradj Ebrahimi, Martin Rerabek, Anne-Flore Nicole Marie Perrin

Broadcasting high dynamic range (HDR) video has been demonstrated as largely preferred when compared to standard dynamic range (SDR), mainly due to its capability of representing more details in dark and bright regions. Additionally, progress over the last ...

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 ...

Low-inertia vacuum-powered soft pneumatic actuator coil characterization and design methodology

Jamie Paik, Matthew Aaron Robertson

Recently developed soft pneumatic actuators (SPAs) powered by negative pressure have demonstrated great potential in the future of soft robotics for their high strength, intrinsic safety, low weight, and often simple design. The majority of these have only ...

A Hybrid Approach for Efficient Color Gamut Mapping

Ultra High Definition (UHD) and High Definition (HD) Television standard recommendations support different color gamuts with the HD gamut much smaller than that of the UHD one. To adapt UHD content to the restricted gamut of HD televisions, a process known ...

Crowd Dynamics and Crowd Capital in Small Teams: Insights from three crowdsourcing exercises in higher education

Christopher Tucci, Gianluigi Viscusi

In this work we aim to study “crowd” dynamics in small teams. To this end, we use the typology of crowds discussed in Viscusi and Tucci [2015] as an interpretive framework, arguing that other characteristics are relevant to identify crowds than the number ...

Multifractal Analysis of Snowfall Recorded Using a 2D Video Disdrometer

Alexis Berne, Timothy Hugh Raupach

Universalmultifractal (UM) analysiswas used to investigate the scaling properties of snowfall at high temporal and spatial resolutions. Snowfall datawere recorded using a 2Dvideo disdrometer (2DVD) in the SwissAlps. Six 1-h-long periods of snowfall, half i ...
