Spectra of atomic theories
نویسندگان
چکیده
For a countable structure B, the spectrum is the set of Turing degrees of isomorphic copies of B. For complete elementary first order theory T , the spectrum is the set of Turing degrees of models of T . We answer a question from [1], showing that there is an atomic theory T whose spectrum does not match the spectrum of any structure.

Monte Carlo calculation of shielding properties of newly developed heavy concretes for megavoltage photon beam spectra used in radiation therapy
Introduction: Globally, the need for radiotherapy as a part of cancer management increases every year. Thus, the shielding for megavoltage radiotherapy rooms is of great importance. Materials and Methods: In the present study, 14 types of developed high-density concrete with densities ranging from 2.45 to 5.11 were simulated by using Monte Carlo method. The linear attenuation coefficient and t...
متن کاملEvidence for Quantisation in Planetary Ring Systems
Absolute radial positions of the main features in Saturn’s ring system have been calculated by adapting the quantum theory of atomic spectra. Fine rings superimposed upon broad rings are found to be covered by a harmonic series of the form N α A(r) 1/2 , where N and A are integers. Fourier analysis of the ring system shows that the spectral amplitude fits a response profile which is characteris...

متن کاملMolecular structure, NBO analysis and vibrational spectra of 2-hydroxy-3-methoxy-N-(2-chloro-benzyl)-benzaldehyde-imine by ab-initio and density functional theory
Quantum chemical calculations have been performed to compute optimized molecular geometry, atomic charges and vibrational characteristics for 2-hydroxy-3-methoxy-N-(2-chloro-benzyl)-benzaldehyde-imine (C15H14O2NCl) in the ground state using restricted Hartree-Fock (RHF) and density functional theory (DFT) methods with 6-31+G** basis set. NBO analysis is also performed. The IR and Raman spectra ...
متن کاملStructures of Micro Films of TiN by Ab-initio Calculation: Implication to X-ray Absorption Near Edge Structure (XANES)
XANES (X-ray Absorption Near Edge Structure) of TiN and TiO2 layers on various substrates have been investigated by comparing the theoretical L3,2 edge of titanium and K edges of nitrogen and oxygen of various crystals, including TiN, TiO, and hcp Ti. The theoretical work is based on the relativistic spin-polarized density functional theory with generalized gradient approximation. XANES spectra...
