The inter-hemispheric symmetry of electroencephalographic (EEG) post-movement beta-event-related synchronization (PMBS) after movements on a drawing board was studied in eight acute stroke subjects with mild hemiparesis and eight normal subjects. A follow-up testing was conducted 3 months after the initial recordings with a twofold purpose: (1) to validate the reproducibility of the experimenta...

Flavor SU(3) symmetry breaking in the hyperon semileptonic decay formfactors is analyzed using the 1/Nc expansion. A detailed comparison with experimental data shows that corrections to f1 are approximately 10%, which agrees with theoretical expectations. Corrections to g1 are compatible with first-order symmetry breaking. A fit to the experimental data allows one to predict the g1 form factor ...

The phonon dynamics of LiV2O5 single crystals is studied using infrared and Raman spectroscopy techniques. The infrared-active phonon frequencies and dielectric constants are obtained by oscillator fitting procedure of the reflectivity data measured at room temperature. The Raman scattering spectra are measured at room temperature and at T=10 K in all nonequivalent polarized configurations. The...

Isobaric quintets provide the best test of isobaric multiplet mass equation (IMME) and can uniquely identify higher order corrections suggestive isospin symmetry breaking effects in nuclear Hamiltonian. The Generalized IMME (GIMME) is a novel microscopic interaction theory that predicts an extension to quadratic form IMME. Only $A=20, 32$ $T=2$ have exotic $T_z = -2$ member ground state determi...

We find fundamental solutions in closed form for a family of parabolic equations with two spatial variables, whose symmetry groups had been determined in an earlier paper by Ferdinando Finkel [12]. We show how these results can be applied in finance to yield closed form solutions for special affine and quadratic two factor term structure models as well as a new class of models with inverse squa...

[1] We compare, on a global scale, the degree of correlation between orientation of stream networks and topographic aspect on Mars and Earth. The orientation of streams on Earth is a reflection of local, underlying geology but, in general, it correlates with regional topographic aspect. However, the orientation of valley networks, prominent features on Mars, thought to be fossils of ancient str...

We rst describe a hierarchical, generative model that can be viewed as a non-linear generalisation of factor analysis and can be implemented in a neural network. The model performs perceptual inference in a probabilistically consistent manner by using top-down, bottom-up and lateral connections. These connections can be learned using simple rules that require only locally available information....
