    Language and thought are not the same thing: evidence from neuroimaging and neurological patients

    Is thought possible without language? Individuals with global aphasia, who have almost no ability to understand or produce language, provide a powerful opportunity to find out. Surprisingly, despite their near-total loss of language, these individuals are nonetheless able to add and subtract, solve logic problems, think about another person's thoughts, appreciate music, and successfully navigate their environments. Further, neuroimaging studies show that healthy adults strongly engage the brain's language areas when they understand a sentence, but not when they perform other nonlinguistic tasks such as arithmetic, storing information in working memory, inhibiting prepotent responses, or listening to music. Together, these two complementary lines of evidence provide a clear answer: many aspects of thought engage distinct brain regions from, and do not depend on, language

    The influence of the Council of Europe's policy on the development of legal regulation of the Russian transport system

    Get PDF
    In recent decades, not only public opinion but also the majority of State’s national legislation and international agreements aimed at modernizing transport systems of the members of the Council of Europe, with a view to improve the spatial organization. The most important factor in determining the particular attention of the Council of Europe to transport problems, is to enhance the safety and quality of transport services and finally to increase the importance of environmental criteria. This article discusses the issues of formation and development of the transport legislation of Russia on the basis of international and European standards.peer-reviewe

    Dielectric response due to stochastic motion of pinned domain walls

    Full text link
    We study the contribution of stochastic motion of a domain wall (DW) to the dielectric AC susceptibility for low frequencies. Using the concept of waiting time distributions, which is related to the energy landscape of the DW in a disordered medium, we derive the power-law behavior of the complex susceptibility observed recently in some ferroelectrics below Curie temperature.Comment: 5 pages, 2 figures, revtex

    ON THE METHODOLOGY OF THE DESIGN OF TRANSPORT AND ECONOMIC BALANCE

    Get PDF
    The article contains a critical analysis of existing methods of forecasting of volumes of transport services on the basis of the analysis of the dynamics of volumes of commodity fl ows at the regional and Federal levels. The recommendations on use of diff erent methods of forecasting for the development of transport and economic balance are presented

    Effect of the medium on the equilibrium between stereoisomeric six- and seven-membered cyclic chair-like acetals. Role of nonspecific and specific interactions

    Get PDF
    Principles for establishing the nature of solvation effects in stereoisomeric equilibria have been formulated. Using 1H NMR spectroscopy, the equilibrium constants have been determined in 12 solvents for the endo and exo isomers of 1,9,10,11,12,12-hexachloro-4,6-dioxatricyclo[7.2.1.02,8]dodec-10-ene which is characterized by a high barrier to stereoisomeric transformations. The results of correlation analysis have shown that solvation of the conformers with dissimilar orientations of the hexachloronorbornene fragment with respect to the chair-like acetal moiety is determined by the polarity and proton-acceptor properties of the medium. Comparison with the data on solvent effect on the equilibrium between 2-isopropyl-5-methoxy1,3-dioxane epimers suggests that the formation of H-complexes is controlled by electronic and conformational factors

    Critical Behaviour of 3D Systems with Long-Range Correlated Quenched Defects

    Full text link
    A field-theoretic description of the critical behaviour of systems with quenched defects obeying a power law correlations xa\sim |{\bf x}|^{-a} for large separations x{\bf x} is given. Directly for three-dimensional systems and different values of correlation parameter 2a32\leq a \leq 3 a renormalization analysis of scaling function in the two-loop approximation is carried out, and the fixed points corresponding to stability of the various types of critical behaviour are identified. The obtained results essentially differ from results evaluated by double ϵ,δ\epsilon, \delta - expansion. The critical exponents in the two-loop approximation are calculated with the use of the Pade-Borel summation technique.Comment: Submitted to J. Phys. A, Letter to Editor 9 pages, 4 figure
