Virtual reality intervention alleviates dyspnoea in patients recovering from COVID-19 pneumonia

Olaf Blanke, Bruno Herbelin, Oliver Alan Kannape, Sylvain Cardin, Sophie Jacqueline Andrée Betka, Jemina Fasola, Florian Lance

Background Immersive virtual reality (iVR)-based digital therapeutics are gaining clinical attention in the field of pain management. Based on known analogies between pain and dyspnoea, we investigated the effects of visual respiratory feedback on persiste ...

Inter- and intra-individual variability in CO2 production and metabolic rate

Dolaana Khovalyg, Mohamad Rida

Carbon dioxide generated by the human body and exhaled (VCO2) is commonly used for ventilation controls, while the metabolic rate (i.e., energy expenditure EE) is an important parameter defining human thermal comfort in buildings. These two parameters are ...

Shear and Breathing Modes of Layered Materials

Nicola Marzari, Giovanni Pizzi, Marco Gibertini

Layered materials (LMs), such as graphite, hexagonal boron nitride, and transition-metal dichalcogenides, are at the center of an ever-increasing research effort, due to their scientific and technological relevance. Raman and infrared spectroscopies are ac ...

Deep learning architectures for estimating breathing signal and respiratory parameters from speech recordings

Mathew Magimai Doss, Zohreh Mostaani

Respiration is an essential and primary mechanism for speech production. We first inhale and then produce speech while exhaling. When we run out of breath, we stop speaking and inhale. Though this process is involuntary, speech production involves a system ...

On The Relationship Between Speech-Based Breathing Signal Prediction Evaluation Measures And Breathing Parameters Estimation

Mathew Magimai Doss, Zohreh Mostaani

The respiratory system is one of the major components of the speech production system. Any alteration in breathing can result in changes in speech. Specific breathing characteristics, such as breathing rate and tidal volume, can indicate a person's patholo ...

Electronic Multi-material Fibers and Textiles: Novel Designs and Applications

Chaoqun Dong

Flexible electronics and particularly soft fibers and textiles are becoming key components in rapidly developing fields such as robotics, health and personal care, sensing, or implantable and wearable devices. Thus far however, the ability to impart soft a ...

Mechanisms of the breathing contribution to bodily self‐consciousness in healthy humans: Lessons from machine‐assisted breathing?

Olaf Blanke, Bruno Herbelin, Oliver Alan Kannape, Elisa Canzoneri, Sophie Jacqueline Andrée Betka, Javier Bello Ruiz

Previous studies investigated bodily self‐consciousness (BSC) by experimentally exposing subjects to multisensory conflicts (i.e., visuo‐tactile, audio‐tactile, visuo‐cardiac) in virtual reality (VR) that involve the participant's torso in a paradigm known ...

Rapid measurement and correction of spatiotemporal B-0 field changes using FID navigators and a multi-channel reference image

Tobias Kober

Purpose To measure spatiotemporal B-0 field changes in real time using FID navigators (FIDnavs) and to demonstrate the efficacy of retrospectively correcting high-resolution T2*-weighted images using a novel FIDnav framework. Methods A forward model of the ...

Photo-physical Properties of Perovskites on Curved Surfaces

Konstantins Mantulnikovs

Organic-inorganic metal halide perovskites (MHPs) have recently attracted increasing attention as highly-efficient light-harvesting materials for photovoltaic applications. The technical ease of solution processing of these materials is one of their major ...

Interferences between breathing, experimental dyspnoea and bodily self-consciousness

Olaf Blanke, Bruno Herbelin, Javier Bello Ruiz, Elisa Canzoneri

Dyspnoea, a subjective experience of breathing discomfort, is a most distressing symptom. It implicates complex cortical networks that partially overlap with those underlying bodily self-consciousness, the experience that the body is one's own within a giv ...

Compact Drop-on-Demand Apparatus Using Light Actuation Through Optical Fibers

Demetri Psaltis, Christophe Moser, Paul Delrot

A drop delivery system comprising a light source; an optical waveguide bringing light from the light source; and a liquid supplying means configured to bring a liquid at a tip of the optical waveguide, wherein the light source and the optical waveguide are ...

A new robust oxygen-temperature sensor for aquatic eddy covariance measurements

Alfred Johny Wüest

The fragility of thin Clark-type glass microelectrodes used in aquatic eddy covariance measurements of benthic oxygen fluxes is a challenge when using this powerful technique. This study presents a new fast-responding dual oxygen-temperature sensor for edd ...

Sleep Disordered Breathing During Live High-Train Low in Normobaric Versus Hypobaric Hypoxia

Jean-Marc Vesin, Grégoire Millet, Sibylle Fallet, Mattia Bertschi

The present study aimed to compare sleep disordered breathing during live high-train low (LHTL) altitude camp using normobaric hypoxia (NH) and hypobaric hypoxia (HH). Sixteen highly trained triathletes completed two 18-day LHTL camps in a crossover design ...

Repeated Double-Poling Sprint Training in Hypoxia by Competitive Cross-country Skiers

Jean-Marc Vesin, Grégoire Millet

Purpose Repeated-sprint training in hypoxia (RSH) was recently shown to improve repeated-sprint ability (RSA) in cycling. This phenomenon is likely to reflect fiber type-dependent, compensatory vasodilation, and therefore, our hypothesis was that RSH is ev ...

Electrical impedance tomography system based on active electrodes

Peter Seitz

Electrical impedance tomography (EIT) can image the distribution of ventilated lung tissue, and is thus a promising technology to help monitor patient breathing to help selection of mechanical ventilation parameters. Two key difficulties in EIT instrumenta ...
