Background: High-velocity carbon ion beams represent the most advanced tool for radiotherapy of deep-seated tumors. Currently, the superiority of carbon ion therapy is more prominent on lung cancer or hepatomas. Materials and Methods: The data for lateral straggling and projected range of monoenergetic 290 MeV/u (3.48 GeV) carbon ions in muscle tissue were obtained from the stopping and range o...

Several formalisms for implementing organizational policies that assign specij2 roles to agents in a MAS have been proposed like the contract net protocol (CNP), the social reasoning mechanism (SRIM), and the distributed computational economy (DCE). Organization self design (OSD) had been proposed to achieve load balancing in a distributed environment. In this paper we propose an adaptive organ...

An algorithm has been developed for the GEANT4 Monte-Carlo package for the efficient computation of screened Coulomb interatomic scattering. It explicitly integrates the classical equations of motion for scattering events, resulting in precise tracking of both the projectile and the recoil target nucleus. The algorithm permits the user to plug in an arbitrary screening function, such as Lens-Je...

The reciprocal f ∗(x) of a polynomial f(x) of degree n is defined by f ∗(x) = xf(1/x). A polynomial is called self-reciprocal if it coincides with its reciprocal. The aim of this paper is threefold: first we want to call attention to the fact that the product of all self-reciprocal irreducible monic (srim) polynomials of a fixed degree has structural properties which are very similar to those o...

Abstract We have developed and successfully tested a low-pressure Time Projection Chamber (TPC) with Gas Electron Multiplier (GEM) readout for Accelerator Mass Spectrometry (AMS). AMS facility in Novosibirsk has problem of separating isobar ions different chemical elements that the same atomic mass. The typical example is radioactive isotopes 10 Be B are used to date geological objects at time ...

In this paper, the investigation of structural and radiation shielding characteristics natural bentonite zeolite was presented. XRD (X-ray diffraction) SEM (scanning electron microscopy) were used to examine properties morphologies minerals. The Electron-Photon Interaction Cross Sections 2017 (EPICS2017) library through EpiXS software obtain photon – including mass attenuation coefficients, mea...

This study aimed to assess the radiation shielding properties of ten low-density high-entropy alloys (LWHEAs) using Phy-X/PSD software analyze various parameters, such as attenuation coefficients (μm and μ), mean free path (λ), effective atomic number (Zeff), removal cross-section (ΣR), in energy range . A comprehensive evaluation was performed compare outcomes provided by HEAs with a materials...

The effect of ionisation quenching for ions is critical experiments relying on the measurement low energy recoils, such as direct Dark Matter searches. We present factor estimates over a range energies protons, $\alpha$-particles, and heavier in H$_{2}$, CH$_{4}$, N$_{2}$, Ar, CO$_{2}$, C$_{3}$H$_{8}$ gases, estimated from respective reference W-value measurements. resulting factors are compare...
