Comparative Analysis of Nuclear Matrix Elements of 0νβ+β+ Decay and Muon Capture in 106Cd
2021
Comparative analyses of the nuclear matrix elements (NMEs) related to the 0νβ+β+ decay of 106Cd to the ground state of 106Pd and the ordinary muon capture (OMC) in 106Cd are performed. This is the first time the OMC NMEs are studied for a nucleus decaying via positron-emitting/electron-capture modes of double beta decay. All the present calculations are based on the proton-neutron quasiparticle random-phase approximation with large no-core single-particle bases and realistic two-nucleon interactions. The effect of the particle-particle interaction parameter gpp of pnQRPA on the NMEs is discussed. In the case of the OMC, the effect of different bound-muon wave functions is studied. peerRevie…
The micro-macro link in understanding sport tactical behaviours: Integrating information and action at different levels of system analysis in sport
2015
Les liens micro-macroscopiques sont centraux dans les sciences du mouvement humain dans la mesure ou ils correspondent aux coordinations et aux echelonnages des comportements moteurs a differents niveaux d’analyse des systemes complexes. Cet aspect de la complexite est un point cle permettant de considerer decision et action comme un comportement de transition a differents niveaux lors de la realisation d’une performance. Les transitions exprimees en termes de bifurcations sont une part importante du mecanisme universel de decision. Les transitions de phase fournissent aussi un moyen de comprendre les liens micro-macro. Dans cet article de synthese, nous developpons un point de vue qui expl…
The micro-macro link in understanding sport tactical behaviours: Integrating information and action at different levels of system analysis in sport
2015
The micro-macro link is a central issue of human movement sciences because it directly refers to coordination and scalability of movement behaviour at different levels of analysis in a complex system. This feature of complexity is a key feature to consider decisions and actions as transitional behaviours at different levels during performance. Transitions expressed through bifurcations are an important part of a universal decisionmaking process. Here we explain how individuals perform decision-making behaviours in a minimal social performance unit ( competing dyads), and how these two levels are linked in a sports team. Finally we discuss some applications of the micro-macro links for the d…

Effect of doping and crystallite size on the electrochemical performance of Li4Ti5O12
2016
Defect spinel phase lithium titanate (Li4Ti5O12) has been suggested as a promising negative electrode material for next generation lithium ion batteries. Flame spray pyrolysis has been shown to be a viable fast, one-step process for synthesis of nanoparticulate Li4Ti5O12. However, due to the rapid quenching that is integral to the process the crystallite size remain very small and non-uniform. To overcome this shortcoming a vertical flow tube furnace was used to increase the high-temperature residence time. This resulted in an increase in the crystallite size and crystallinity of the product. As a result of this increase the electrochemical performance of the Li4Ti5O12 was markedly improved…

A software receiver adaptive phase lock loop method
2009
The aim of this paper is to introduce a new and relatively simple algorithm which is capable to tune the parameters of the loop filter in a phase lock loop, like the one that can be found in a global navigation satellite system receiver. The parameters are chosen while the system is running, in order to make the bandwidth of the filter adaptive with respect to the signal dynamic and strength. A wider bandwidth is obtained to make the filter more reactive when searching the carrier, while the bandwidth gets narrower when the system is in the tracking state, in order to cut off as much noise as possible. The algorithm is based on the observation of the estimated variance of the phase lock loo…
Improvement of partition coefficients determination of aroma compounds in food matrices by the phase ratio variation method
2011
The Phase Ratio Variation (PRV) method is a very valuable method commonly used for liquid/vapor partition coefficients data acquisition of aroma compounds. Nevertheless, some limits are linked to this method, especially for volatile compounds. A careful examination of the PRV equation leads us to propose the following expression: 1/Cvap-real =(nliq/n0) x 1/Cvap-ideal = (nliq/n0) x (1/KC0 + (1/Co) b), We performed an examination for two cases of K values (K1=0.001 and K2=0.05), putting forward that a carefully choice of b range values is crucial for reliability of the regression calculation 1/A versus b.
