Effects of Exogenous Electromagnetic Fields on a Simplified Ion Channel Model
In this paper, we calculate the effect of an exogenous perturbation (an electromagnetic field [EMF] oscillating in the range of microwave frequencies in the range of 1 GHz) on the flux of two ion species throu...

A General Learning Rule for Network Modeling of Neuroimmune Interactome
We propose a network model in which the communication between its elements (cells, neurons and lymphocytes) can be established in various ways. The system evolution is driven by a set of equations that encodes...

Fission of the44Ti,56Ni and74, 76Kr nuclei formed by heavy-ion reactions
The decay width, mean lifetime and fission probability of the44Ti,56Ni and74, 76Kr nuclei have been determined in the framework of the statistical model of nuclear reactions. A comparison is made with some experi...

Experimental evidence of a charge and energy scaling law for ion blocking in thin crystals
Blocking patterns for different ions elastically scattered by a very thin Si crystal have been measured. The dependence of the “volumes” and of the shapes of the experimental blocking dips on the ion character...

Crystal blocking measurement of time delays in the16O+28Si reaction
The blocking patterns around the 〈110〉 axis of a Si single crystal have been measured for the products of the reaction16O(100 MeV)+28Si atθ lab=30° withZ from 8 to 13. The experimental set-up and data reduction m...

High-speed Monte Carlo calculations of crystal blocking dips
A new method for the calculation of blocking dips in single-crystals is described. It makes use of the continuum model to generate the distribution of initial transverse energies and of a Monte Carlo sampling ...

Models for axial blocking in lifetime measurements
Three models based on the idea that thermal vibrations in the emitting atom are important in blocking phenomena, and that particles are detected within a solid angleΩ if emitted beyond a distancer c from the stri...

Experimental study of the α-12C elastic scattering.R-matrix analysis of the phase shifts and16O levels
Elastic scattering of alpha-particles from12C has been experimentally studied for16O excitation energies between 9.4 and 14.7 MeV. The phase shifts obtained from angular distributions have been analysed in terms ...

Blocking with realistic decay functions
In this paper we discuss the influence of a nonexponential decay on the determination of compound nuclear-reaction times by means of the blocking effect. In particular, with reference to the reaction92Mo(p, p′)92

Compound nuclear reaction times and level densities from a blocking experiment in molybdenum
The 〈111〉 axial blocking in a natural Mo crystal has been used to measure the92Mo(p,p′)92Mo* (1.5 MeV, 2+) reaction times at proton energies between 7.5 and 9.5 MeV. A computer simulation was employed to extract ...
