Recurrent sigmoidal neural networks with asymmetric weight matrices and recurrent neural networks with nonmonotone transfer functions can exhibit ongoing uctuations rather than settling into point attractors. It is, however, an open question if these uctuations are the sign of low dimensional chaos or if they can be considered as close to stochastic. We report on the calculation of the correlat...

Following the lead of a recent work we perform a variational principle model calculation for the nuclear caloric curve. A Skyrme type interaction with and without momentum dependence is used. The calculation is done for a large nucleus, i.e, in the nuclear matter limit. Thus we address the issue of volume fragmentation only. Nonetheless the results are similar to the previous, largely phenomeno...

Nowadays, marketing serves the purpose of maximizing customer lifetime value (CLV) and customer equity, which is the sum of the lifetime values of the company’s customers. But, CLV calculation encounters some difficulties which limit the usage of this technique. Nonetheless, companies looking for methods to know how to calculate their customers’ CLV. In this paper, fuzzy classification rules we...

We report on the results of our calculation of meson correlators in a finite volume. The calculation is carried out in the quenched approximation near the chiral limit (down to mq = 2.6 MeV) using the overlap fermion. For these small quark masses, the scalar and pseudo-scalar correlators are well approximated with a few hundred eigenmodes. The results for both connected and disconnected correla...

A new study is reported of a lattice QCD calculation of the K → ππ decay amplitude with the Wilson quark action in the quenched approximation at β = 6.1. The amplitude is extracted from the K → ππ Green function, and a conversion to the continuum value is made employing a recent one-loop calculation of chiral perturbation theory. The result is consistent with the experimental value if extrapola...

This note gives a short review of the statistical issues concerning upper limit calculation and claiming of discovery arising in the search for exotic physics with neutrino telescopes. Low sample sizes and significant instrumental uncertainties require special consideration. Methods for treating instrumental or theoretical uncertainties in the calculation of limits or discovery are described. S...

A model calculation of nucleon-nucleon scattering is presented, which results in an amplitude that in the elastic high energy limit realizes the Wu-Yang idea regarding the relation between the elastic form factor of the nucleon and the differential cross section; and which is consistent with the behavior of the differential cross section for the production of nucleon resonances. The calculation...
