''Isokinetic intervention in microtraumatic shoulder instability: an update''
2012
Gremeaux, V. | Croisier, J. L. | Forthomme, B.; International audience; ''Aim. Aim of the present study was to carry out a critical analysis of the use of isokinetic dynamometers for evaluation and rehabilitation in microtraumatic shoulder instability. Methods. A non-systematic literature review was conducted on Medline using the following key words: "isokinetics", "shoulder instability", "evaluation", "rehabilitation". We also analyzed the related articles, and compiled a database of expert opinion. Results. Despite a lack of consensus on testing modalities, lateral and medial rotator muscle strength can be safely and reliably assessed on isokinetic devices in subjects presenting with micr…
Dead-time impact on the harmonic distortion and conversion efficiency in a three-phase five-level Cascaded H-Bridge inverter: mathematical formulatio…
2023
To avoid leg short-circuit in inverters, dead time must be introduced on leg gate signals. Dead time affects the inverter output voltage fundamental harmonic amplitude, voltage harmonic distortion and inverter efficiency by introducing additional voltage drops. In this regard, dead time effects have been widely investigated for traditional two-level three-phase voltage source inverters in the literature but not extensively for multilevel topology structures. This paper provides a detailed analysis of dead time impact on the harmonic distortion and efficiency of Cascaded H-Bridges Multilevel Inverters (CHBMIs). For this purpose, a general mathematical formulation to determine voltage drop du…
A genome-wide view of Caenorhabditis elegans base-substitution mutation processes
2009
Knowledge of mutation processes is central to understanding virtually all evolutionary phenomena and the underlying nature of genetic disorders and cancers. However, the limitations of standard molecular mutation detection methods have historically precluded a genome-wide understanding of mutation rates and spectra in the nuclear genomes of multicellular organisms. We applied two high-throughput DNA sequencing technologies to identify and characterize hundreds of spontaneously arising base-substitution mutations in 10 Caenorhabditis elegans mutation-accumulation (MA)-line nuclear genomes. C. elegans mutation rate estimates were similar to previous calculations based on smaller numbers of m…
Modulation of lipid metabolism and colonic microbial diversity of high-fat-diet C57BL/6 mice by inulin with different chain lengths
2019
Abstract The physicochemical properties, biological functions and microbial degradation of inulins differ according to their degree of polymerization. However, the relationship between inulin activities and its effect on gut microbiota remains unknown. In this study, high fat diet with inulin (1 or 5 g/kg·bw), either with short or long chains groups were administered to different groups of mice (n = 10) for 10 weeks in order to investigate the effect of inulin on the microbial diversity of the animals. Litchi pericarp procyanidins (LPPC) were used for comparison purposes. Furthermore, the lipid metabolism and key regulator genes in mice were determined. The results indicated that natural in…
Grip Force Adjustments Reflect Prediction of Dynamic Consequences in Varying Gravitoinertial Fields
2018
International audience; Humans have a remarkable ability to adjust the way they manipulate tools through a genuine regulation of grip force according to the task. However, rapid changes in the dynamical context may challenge this skill, as shown in many experimental approaches. Most experiments adopt perturbation paradigms that affect only one sensory modality. We hypothesize that very fast adaptation can occur if coherent information from multiple sensory modalities is provided to the central nervous system. Here, we test whether participants can switch between different and never experienced dynamical environments induced by centrifugation of the body. Seven participants lifted an object …
uMemristorToolbox: Open source framework to control memristors in Unity for ternary applications
2020
This paper presents uMemristorToolbox, a novel open source framework that reads and writes non-volatile ternary states to memristors. The Unity (C#) framework is a port of the open source Java project Memristor-Discovery and adds a closed-loop ternary memory controller to enable both PC and real-time embedded ternary applications. We validate the closed-loop ternary memory controller in an embedded system case study with 16 M+SDC Tungsten dopant memristors. We measure an average switching speed of 3 Hz, worst case energy usage of 1 μW per switch, 0.03% random write error and no decay in (non-volatile) state retention after 15 minutes. We conclude with observations and open questions when wo…
Estimation of power supply harmonic impedance using a controlled voltage disturbance
2002
A novel method for power system impedance estimation is presented. The method employs a power converter to inject a voltage transient onto the supply system. The impedance is estimated through correlation of the measured voltage and current transients. Simulations and experimental results demonstrate the effectiveness of this measurement technique.
A metabolism of Adam and Eve: Damien Hirst meets Edvard Munch
2016
Sari Kuuva, University of Jyvaskyla Sari Kuuva, PhD (in cognitive science, 2007 and art history, 2010) is a post-doctoral researcher who works at the Department of Art and Cultural Studies at the University of Jyvaskyla. She has studied the relationship between art, aesthetics and psychology, particularly the concept of the symbol and the problematics of experiencing and creating visual art. Among Kuuva’s main publications relating to the art of Edvard Munch are: Symbol, Munch and Creativity: Metabolism of Visual Symbols (University of Jyvaskyla 2010); ‘Emotional creativity in art: case scream’ in Mind and Matter: Selected Papers of Nordic 2009 Conference for Art Historians (Helsinki, Socie…
Il catalano nella Corte Aragonese di Napoli, riflesso in documenti bilingui della cancelleria di Ferrante. Uno studio storico-sociale
2013
Riassunto: Nel presente lavoro viene analizzato il fenomeno del code switching in una prospettiva storico-sociale. In particolare, focalizzeremo la nostra attenzione su cinque lettere bilingui del Codice Aragonese (1458-1460), un registro cancelleresco della corte aragonese a Napoli, in cui si passa dal catalano o dal castigliano al napoletano e viceversa. Analizzando il contesto storico e sociale nel quale le lettere sono state scritte, proveremo a trarre delle conclusioni sulle motivazioni per cui si è realizzato il rispettivo cambio di codice linguistico. Nello stesso modo cercheremo di spiegare la tendenza di esprimersi in catalano in situazioni emozionali o di tensione politica, ma anc…
