<p>The article reflects various approaches of philosophy and programming to methods for solving the technical problem creating software implementation artificial consciousness (AC). Various purposes creation basic determining nature AC are described. To solve an AC, architecture is proposed that includes ten levels, starting from level collecting systematizing information about external world ending with upper influence on it, agreed person decision-making. The features delimitation...
<div><p>The article deals with the problem of ternary logic, in which, except for states “yes” and “no” (inherent traditional binary logic), is introduced “third state” U—“Unknown”, also addresses issues technical mathematical problems that arise this case. To do this, logic Stephen Kleene has been corrected, implementation calculations using probabilistic polynomials over field real numbers proposed. The authors analyze process addition to regard approach Kleene, who an...
As a stabilizer for low-temperature superconductors, Al has found limited use due to the metallurgical difficulty and low melting point of Al. However, now that processing MgB2 wires at 600 °C been demonstrated, all advantages stabilization can be realized. With in mind, we describe situ powder-in-tube 'low temperature processing' mixed Mg+B powders an tube lined with protective Fe barrier. Reaction heat treatment °C, up 3 h, led complete formation; furthermore, no reaction between barrier...
We study N=2, d=4 attractor equations for the quantum corrected two-moduli prepotential $\mathcal{F}=st^2+iλ$, with $λ$ real, which is only correction preserves axion shift symmetry and modifies geometry. In classical case black hole effective potential known to have a flat direction. found that in presence of D0-D6 branes exhibits direction as well. It corresponds non-BPS $Z\neq 0$ solutions equations. Unlike case, acquire non-zero values field. For cases D0-D4 D2-D6 reduces separate...
We construct a two-dimensional N=8 supersymmetric quantum mechanics which inherits the most interesting properties of N=2, d=4 Yang–Mills theory. Analyzing superfield constraints, we show that only complex scalar fields from N=2,d=4 vector multiplet become physical bosons in d=1. The rest bosonic components are reduced to auxiliary fields, thus giving rise (2,8,6) supermultiplet general action for this and demonstrate it possesses duality symmetry extended fermionic sector also explicitly...
We propose a unified superfield formulation of $N=4$ off-shell supermultiplets in one spacetime dimension using the standard superspace. The main idea our approach is gluing together two linear along their fermions. functions defining such obey system equations. Each solution this provides new supermultiplet, or nonlinear, modulo equivalence transformations. In way we reproduce all known and nonlinear $N=4$, $d=1$ some ones. Particularly interesting an explicit construction hypermultiplets.
The attractor mechanism in five dimensional Einstein-Maxwell Chern-Simons theory is studied. expression of the five-dimensional rotating black object potential depending on Taub-Newman-Unti-Tamburino, electric and magnetic charges as well all scalar gauge fields, investigated. first order formalism $d=5$ constructed analyzed. We derive a general defining fake superpotential which valid for charge configurations. An explicit constructed, very special geometries, case vanishing...
The article discusses the insufficiency of “leading families fl ora” (“spectrum leading flora”) analysis – a simple list ranked by species richness. authors call such pseudo-analysis “accounting-bureaucratic”, since these fi gures themselves do not carry any biological meaning. limitations imposed on possibility comparing different approaches to ora’s volume are considered. It is indicated that A.P. Khokhryakov’s approach focusing family, ranking third in number helps attributing zonality...
We demonstrate that two-dimensional N=8 supersymmetric quantum mechanics which inherits the most interesting properties of $N=2, d=4$ SYM can be constructed if reduction to one dimension is performed in terms basic object, i.e. vector multiplet. In such a only complex scalar fields from multiplet become physical bosons $d=1$, while rest bosonic components are reduced auxiliary fields, thus giving rise {\bf (2, 8, 6)} supermultiplet $d=1$. construct general action for this with all possible...
We demonstrate that in $N=8$ supersymmetric mechanics with linear and nonlinear chiral supermultiplets one may dualize two auxiliary fields into physical ones such a way the bosonic manifold will be hyper-K\"ahler one. The key point of our construction is about different dualizations components. One them turned standard through its replacement by total time derivative some field. other field which obeys condition ${\ensuremath{\partial}}_{t}(\mathrm{Im}A+\mathrm{Im}B)=0$ dualized Lagrange...
We construct a new two-dimensional N=8 supersymmetric mechanics with nonlinear chiral supermultiplet. Being intrinsically this multiplet describes 2 physical bosonic and 8 fermionic degrees of freedom. the most general superfield action sigma-model type propose its simplest extension by Fayet-Iliopoulos term. The interesting property constructed system is geometry in subsector, which different from special Kahler one characterizing case linear
The motion of a particle near the Reissner-Nordstr\"om black hole horizon is described by conformal mechanics. In this paper we present an extended one-dimensional analysis $N=4$ superconformal mechanics coupled to $n$ copies $N=8$, $d=1$ vector supermultiplets. scalar manifold multiplet sector constructed system possesses supersymmetry and, therefore, special K\"ahler type. Coupling multiplets dilaton superfield makes theory invariant under symmetry, thus reducing number supersymmetries...
The effects of magnetic nanoparticle doping on superconductivity MgB2/Fe wires have been investigated. Fe2B and SiO2-coated particles with average diameters 80 150 nm, respectively, were used as dopands. MgB2 different contents (0, 3, 7.5, 12 wt.%) sintered at temperature 750°C. magnetoresistivity critical current density Jc measured in the range 2–40 K field B ≤ 16 T. Both transport determined. Superconducting transition Tc doped decreases quite rapidly level (~ 0.5 per wt.%). This results...
