Universal neural field computation

Turing machines and G\"odel numbers are important pillars of the theory of computation. Thus, any computational architecture needs to show how it could relate to Turing machines and how stable implementations of Turing computation are possible. In this chapter, we implement universal Turing computation in a neural field environment. To this end, we employ the canonical symbologram representation of a Turing machine obtained from a G\"odel encoding of its symbolic repertoire and generalized shifts. The resulting nonlinear dynamical automaton (NDA) is a piecewise affine-linear map acting on the unit square that is partitioned into rectangular domains. Instead of looking at point dynamics in phase space, we then consider functional dynamics of probability distributions functions (p.d.f.s) over phase space. This is generally described by a Frobenius-Perron integral transformation that can be regarded as a neural field equation over the unit square as feature space of a dynamic field theory (DFT). Solving the Frobenius-Perron equation yields that uniform p.d.f.s with rectangular support are mapped onto uniform p.d.f.s with rectangular support, again. We call the resulting representation \emph{dynamic field automaton}.Comment: 21 pages; 6 figures. arXiv admin note: text overlap with arXiv:1204.546

Holistic competence level of Corporate governance bodies in the selection process in the Czech Republic

The main objective of the paper has been based on two-phased research to compare the level of holistic competence in selecting the members of governance bodies (Managing Board and Supervisory Board) between the two periods. Holistic competence was defined based on a holistic model of competence by Porvaznik (2008) and implementation of the model was subsequently described in the Corporate Governance based on a study by Taraba, Bartosikova and Bilikova (2014). Using methods of descriptive statistics and spider charts two data files were compared. Data were collected by questionnaire survey conducted among members of the Corporate Governance bodies operating in the Czech Republic in the period from April 2012 to April 2013 (Phase I) and in the period from September 2013 to February 2014 (Phase II.). There is also discussion as a part of paper conclusion which formulates the underlying causes of changes in the holistic assessment of competence in the selection of the members of corporate governance bodies and the recommendations made in this area

A search for free quarks in deep inelastic muon scattering

A search was made at the CERN SPS for long-lived fractionally charged particles produced in deep inelastic muon interactions on a Be target using the existing muon beam line as a spectrometer. No such particles were found, leading to upper limits for the production cross section of the order of 10-36 cm2 for 200 GeV incident muon momentum and quark masses below 9 GeV for the 2 3 charge and 15 GeV for 1 3 charge. © 1983

MEASUREMENT OF THE DEUTERON STRUCTURE FUNCTION F2 AND A COMPARISON OF PROTON AND NEUTRON STRUCTURE

The deuteron structure function F2d has been measured in 280 GeV μ+ d interactions. Existing measurements of F2p, made with the same apparatus, are used to calculate F2p-F2n and F2n F2p. The ratio F2n F2p has a similar x dependence to that of earlier measurements at lower Q2. © 1983
