An independence property for general information

The aim of this paper was a generalization of independence propery proposed by Kampè de Fèriet and Forte in Information Theory withou probability, called "general infromation". Therefore, its application to fuzzy sets has been presented

General information conditioned by a variable event

The aim of this paper is to present, by axiomatic way, an idea about the general conditional information of a single, fixed fuzzy set when the conditioning fuzzy event is variable. The properties of this conditional information are translated in a system of functional equations. Some classes of solutions of this functional system are founded

General conditioned and aimed information on fuzzy setting

In this paper our investigation on aimed information, started in 2011, will be completed on fuzzy setting. Here will be given a form of information for fuzzy setting, when it is conditioned and aimed. This information is called "general", because it is defined without using probability or fuzzy measure

Renormalization of the Spin-dependent WIMP scattering off nuclei

We study the amplitude for the spin-dependent WIMP scattering off nuclei by including the leading long-range two-body currents in the most important isovector contribution. We show that such effects are essentially independent of the target nucleus and, as a result, they can be treated as a mere renormalization of the effective nucleon cross section or, equivalently, of the corresponding effective coupling with values around 25%.Comment: 15 pages, 4 figures, 2 tables. arXiv admin note: text overlap with arXiv:1211.321

Heavy sterile neutrino in dark matter searches

Sterile neutrinos are possible dark matter candidates. We examine here possible detection mechanisms, assuming that the neutrino has a mass of about 50 keV and couples to the ordinary neutrino. Even though this neutrino is quite heavy, it is non relativistic with a maximum kinetic energy of 0.1 eV. Thus new experimental techniques are required for its detection. We estimate the expected event rate in the following cases: i) Measure electron recoils in the case of materials with very low electron binding. ii) Low temperature crystal bolometers. iii) Spin induced atomic excitations at very low temperatures, leading to a characteristic photon spectrum. iv) Observation of resonances in antineutrino absorption by a nucleus undergoing electron capture. v) Neutrino induced electron events beyond the end point energy of beta decaying systems, e.g. in the tritium decay studied by KATRIN.Comment: 17 pages, 8 figures ; revised figures, corrected typos, additional comments ; results unchange

On two conditional entropies without probability

We generalize the conditional entropy without probability given by Benvenuti in [1] and we recognize that this form is the most general compatible with the given properties. Then we compare our form of conditional entropy given in [4] with Benvenuti’s one.Peer Reviewe
