Could Low-Frequency Electromyostimulation Training be an Effective Alternative to Endurance Training? An Overview in One Adult
2014
This preliminary study aimed to investigate the effects of a six-week low-frequency electromyostimulation training (10Hz) on the cardiovascular, respiratory and muscular systems. To that purpose, aerobic capacity, knee extensor muscles strength and architecture, muscle sympathetic nervous activity, blood pressure and heart rate have been evaluated in one healthy male subject (33 year-old, 1.73 m, 73 kg). Results showed improvement of aerobic capacity (+4.5% and +11.5% for maximal oxygen uptake and ventilatory threshold) and muscle strength (+11% and +16% for voluntary and evoked force). Moreover, for the first time, this study demonstrated low-frequency training effects on muscle architectu…
Theoretical estimates of supernova-neutrino cross sections for the stable even-even lead isotopes: Charged-current reactions
2016
A detailed study of the charged-current supernova electron neutrino and electron antineutrino scattering off the stable even-mass lead isotopes A = 204, 206, and 208 is reported in this work. The proton-neutron quasiparticle random-phase approximation (pnQRPA) is adopted to construct the nuclear final and initial states. Three different Skyrme interactions are tested for their isospin and spin-isospin properties and then applied to produce (anti)neutrino-nucleus scattering cross sections for (anti)neutrino energies below 80 MeV. Realistic estimates of the nuclear responses to supernova (anti)neutrinos are computed by folding the computed cross sections with a two-parameter Fermi-Dirac distr…
Effect of energy density on liking and on caloric adjustment conditioning after sweet beverage exposure in children aged 8-11 y
2014
The contribution of sweet beverages to weight gain in children and adolescents is controversial. The present study was conducted to study, in 8-11 year-old children, the influence of energy conditioning on liking and on caloric adjustment after sweet beverages exposure. We also studied the stability of the conditioning effects after a period without exposure and an extinction period. Children (n = 44) were exposed to 2 flavored sweetened beverages: a high energy version (HE: 150kcal) and a no energy version (NE: 0kcal). During a 4-wk conditioning period, children were exposed either 2 or 7 times to each beverage. During a 3-wk stability period children were not exposed to any beverage. Duri…
LASSO regression via smooth L1-norm approximation
2010
This paper discusses estimation of regression model with LASSO penalty when the L1-norm is replaced with its parametric smooth approximation. The resulting parameter estimators are more manageable than those from standard LASSO, standard errors are easy computed via a sandwich formula, and the model degrees of freedom may be computed straightforwardly. Moreover the resulting objective function may be minimized using usual optimization algorithms for regular models, for instance Newton-Raphson or iterative least squares.
Production of (anti-)He-3 and (anti-)H-3 in p-Pb collisions at √sNN = 5.02 TeV
2020
The transverse momentum (p(T)) differential yields of (anti-)He-3 and (anti-)H-3 measured in p-Pb collisions at √sNN = 5.02 TeV with ALICE at the Large Hadron Collider (LHC) are presented. The ratios of the p(T)-integrated yields of (anti-)He-3 and (anti-)H-3 to the proton yields are reported, as well as the pT dependence of the coalescence parameters B-3 for (anti-)He-3 and (anti-)H-3. For (anti-)He-3, the results obtained in four classes of the mean charged-particle multiplicity density are also discussed. These results are compared to predictions from a canonical statistical hadronization model and coalescence approaches. An upper limit on the total yield of (4)(He) over bar is determine…
An antique lead coffin discovered in Évreux (Eure): a multidisciplinary study
2013
The Roman cemetery of le Clos au Duc in Évreux (Eure) lasted from the 1st to the 4th c. AD. The most common funerary practice in the 1st c. AD was cremation. From the beginning of the 2nd c. AD this rapidly gave place to inhumation burials. By the end of the 3rd c. lead coffins could be found in burials, but it remained a minority practice reserved for an elite. The 2010 excavation in Évreux allowed the recovery of an example of these. It was incomplete, but the good preservation of its remains made a multidisciplinary study possible. Apart from the bones of a young woman, the lead coffin contained coins, textile, fur, calcite (CaCO3) and insects. These results make it possible to retrace t…
Liturgie anlässlich der Staatsund Nationalfeierlichkeiten in Polen Geschichte, Probleme und Herausforderungen
2018
Historia, problemy i wyzwania. Historia Polski od przyjęcia chrztu w 966 r. pokazuje, jak pewne wydarzenia społeczne łączono z celebracjami liturgii. W artykule została podjęta próba pokazania nie tylko historii tego zjawiska, ale też problemów, jakie się z nim wiązały. Łączenie wątków religijnych ze świętowaniem wydarzeń narodowych miało miejsce wtedy, gdy pojawiało się zagrożenie wewnętrzne lub zewnętrzne. Przykładem są tzw. śluby lwowskie króla Jana Kazimierza, który 1 kwietnia 1656 r. uroczystym aktem religijno-państwowym oddał Rzeczpospolitą pod opiekę Matki Bożej, którą ogłosił Patronką oraz Królową Królestwa Polskiego i wszystkich jego ludów. Fakt ten przyczynił się zdecydowanie do t…
Low-rank approximation based non-negative multi-way array decomposition on event-related potentials
2014
Non-negative tensor factorization (NTF) has been successfully applied to analyze event-related potentials (ERPs), and shown superiority in terms of capturing multi-domain features. However, the time-frequency representation of ERPs by higher-order tensors are usually large-scale, which prevents the popularity of most tensor factorization algorithms. To overcome this issue, we introduce a non-negative canonical polyadic decomposition (NCPD) based on low-rank approximation (LRA) and hierarchical alternating least square (HALS) techniques. We applied NCPD (LRAHALS and benchmark HALS) and CPD to extract multi-domain features of a visual ERP. The features and components extracted by LRAHALS NCPD…
Glottal Source Features for Automatic Speech-Based Depression Assessment
2017
Depression is one of the most prominent mental disorders, with an increasing rate that makes it the fourth cause of disability worldwide. The field of automated depression assessment has emerged to aid clinicians in the form of a decision support system. Such a system could assist as a pre-screening tool, or even for monitoring high risk populations. Related work most commonly involves multimodal approaches, typically combining audio and visual signals to identify depression presence and/or severity. The current study explores categorical assessment of depression using audio features alone. Specifically, since depression-related vocal characteristics impact the glottal source signal, we exa…
