[en] In the late nineteenth century, the Japanese seismologist Omori discovered the first law of earthquake physics, which states that the rate of aftershocks decreases hyperbolically with time. Over the years since then, there has been a vast amount of literature on this law, and the significance of its discovery has been universally recognized. There is, however, a profound division of opinion as to the interpretation of the law. Some argue that Omori just proposed a simple data-fitting formula and replace this formula by a power-law one with a negative fractional exponent, whereas for others the Omori law makes physical sense. The paper describes the history and essence of Omori’s discovery, with special attention paid to interpretational questions. It is shown that Omori’s original formulation of the law correlates well with the current understanding of the rock destruction mechanism at the earthquake focus. (from the history of physics)

[en] Neutron beam guides are very convenient when the experiments require high-intensity cold-neutron beams. In this paper it is discussed the propagation of a cold-neutron beam through a guide suitably bent, taking into account the effects due to the guide curvature and those produced by the gravity. The main features of the propagated neutron beam are discussed

[en] The experimental status of neutrino oscillation searches at accelerators is presented. Results and limits on mass differences and mixing angles from different experiments are given. Perspectives on future projects to explore larger region of mass difference and mixing parameters space are discussed

[en] A method is presented, based on transport matrix operators, intended to study cold neutron propagation in neutron beam guides. These transport operators have been calculated for guides of arbitrary length and curvature taking into account the effects of gravity and the effective reflectivity at the guide walls. This technique was applied to the ILL H53 neutron beam used in the Grenoble neutron-antineutron oscillation experiment showing a good agreement between the calculations and the experimental data.

[en] Prospects for neutrino oscillation experiments with neutrino factories based on muon decay and high-energy neutrino superbeams are discussed with a special emphasis on the neutrino beam properties. In particular production of a ν superbeam of very high intensity and low energy has been considered

[en] The predictions of meson production by 450 GeV/c protons on Be using the Monte Carlo FLUKA standalone and GEANT-FLUKA and GEANT-GHEISHA in GEANT are compared with available experimental measurements. The comparison enlightens the improvements of the hadronic generator models of the present standalone code FLUKA with respect to the 1992 version which is embedded into GEANT-FLUKA. Worse results were obtained with the GHEISHA package. A complete simulation of the SPS neutrino beam line at CERN showed significant variations in the intensity and composition of the neutrino beam when FLUKA standalone instead of the GEANT-FLUKA package is used to simulate particle production in the Be target
