In this work, we deal with blind source separation of a class of nonlinear mixtures. The proposed method can be regarded as an adaptation of the solutions developed in [1, 2] to the considered mixing system. Also, we provide a local stability analysis of the employed learning rule, which permits us to establish necessary conditions for an appropriate convergence. The validity of our approach is...

Axion-photon mixing has been proposed as an alternative to acceleration as the explanation for supernovae dimming. We point out that the loss of photons due to this mixing will induce a strong asymmetry between the luminosity, dL(z), and angular-diameter distance, dA(z), since the latter is unaffected by mixing. In a first search for such asymmetry we introduce an amplitude A, such that A = 1 i...

Thermodynamic consistency test of isothermal vapor-liquid equilibrium (VLE) data of various binary systems containing Carbon dioxide (CO2)/Room temperature ionic liquids (RTILs) have been investigated in wide ranges of pressures in each isotherm precisely. In this paper Generic van der Waals (GvdW) equation of state (EoS) coupled with modified van der Waals Berthelot mixing rule has ...

The objective of this contribution was to explore the effect of thermodynamic model selection on predicting the solubility of hydrogen in Pyrolysis Gasoline (PYGAS). In order to do this, different combinations of cubic equations of state (EOS), cohesion functions and mixing rules were compared, using both own algorithms and those implemented in the PRO/II 8.0 process simulation software. The mo...

In bilingual communities, mixing languages is avoided in formal schooling: even if two languages are used on a daily basis for teaching, only one language is used to teach each given academic subject. This tenet known as the one subject-one language rule avoids mixing languages in formal schooling because it may hinder learning. The aim of this study was to test the scientific ground of this as...

This paper gives a comparative study of the K-means algorithm and the mixture model (MM) method for clustering normal 7 data. The EM algorithm is used to compute the maximum likelihood estimators (MLEs) of the parameters of the MM model. These parameters include mixing proportions, which may be thought of as the prior probabilities of different clusters; the maximum 9 posterior (Bayes) rule is ...

We study realistic 3D laser cooling of positronium (Ps) in the presence a magnetic field. Triplet and singlet states mixing due to field, dynamical Stark effect, generally produce higher annihilation rates than zero-field case. is efficient only at very low field $B\ensuremath{\lesssim}50\phantom{\rule{0.16em}{0ex}}\mathrm{mT}$ high values $B⪆0.7\phantom{\rule{0.16em}{0ex}}\phantom{\rule{0.16em...

the critical properties of a solute are required for modeling of the solubility by the equation of state. for many compounds, the critical properties are not available. so, group contribution method is utilized as a common method to estimate these properties. but, it leads to the consecutive errors in calculations of the solubility modeling. in this study, soave-redlish-kowang (srk) and peng-ro...

We summarize three alternative extensions of the quark-valence picture of nucleon strangeness and spin, including (1) gluon spin in QCD, (2) Bjorken sum rule and QCD, (3) D–E meson mixing and tadpole leakage. All three approaches suggest that ∼ 40% of the nucleon’s spin (as well as its momentum) resides with quarks, but that less than 6% is due to strange quarks.

B → πlν decay is studied in the effective theory of heavy quark with infinite mass limit. The leading order heavy flavor-spin independent universal wave functions which parameterize the relevant matrix elements are evaluated via light cone sum rule method in the effective theory. The important quark mixing matrix element |V ub | is then extracted via B → πlν decay mode.
