String Theory Modifies Quantum Mechanics

We argue that the light particles in string theory obey an effective quantum mechanics modified by the inclusion of a quantum-gravitational friction term, induced by unavoidable couplings to unobserved massive string states in the space-time foam. This term is related to the $W$-symmetries that couple light particles to massive solitonic string states in black hole backgrounds, and has a formal similarity to simple models of environmental quantum friction. It increases apparent entropy, and may induce the wave functions of macroscopic systems to collapse.Comment: 18 pages, CERN-6595/9

Influence of scattering processes on electron quantum states in nanowires

In the framework of quantum perturbation theory the self-consistent method of calculation of electron scattering rates in nanowires with the one-dimensional electron gas in the quantum limit is worked out. The developed method allows both the collisional broadening and the quantum correlations between scattering events to be taken into account. It is an alternativeper seto the Fock approximation for the self-energy approach based on Green’s function formalism. However this approach is free of mathematical difficulties typical to the Fock approximation. Moreover, the developed method is simpler than the Fock approximation from the computational point of view. Using the approximation of stable one-particle quantum states it is proved that the electron scattering processes determine the dependence of electron energy versus its wave vector

Quasi freestanding graphene on SiC 0001 via cobalt intercalation of zero layer graphene

Modification of the electronic and crystal structure of zero layer graphene grown on 6H SiC 0001 after Co intercalation is reported. Using a wide range of techniques including angle resolved photoelectron spectroscopy, x ray photoelectron spectroscopy, Raman spectroscopy, low energy electron diffraction, we found that zero layer graphene on SiC transforms into graphene monolayer as a result of cobalt intercalation. The Dirac cone of amp; 960; band characteristic of quasi freestanding graphene is observed. In combination with high resolution transmission electron microscopy and atomic force microscopy data, we conclude that ultrathin silicide CoSi CoSi2 structure is formed between graphene and SiC substrate. Investigation of magnetic properties reveals ferromagnetic behavior with open hysteresis loop. The results of this work are the basis for further implementation of magneto spin orbit graphene on a semiconducting substrate and are important for the future application of such graphene in spintronic

“Aut Fitness” — a Technology for Organizing Classes on Adaptive Physical Education for Children with ASD

The motor sphere in children with ASD is frequently affected in association with low social and communicative skills. This makes development of individually tailored physical education programs especially important. We present the results of contemporary foreign studies of the motor abilities of children with ASD that point to the efficiency of adaptive physical activities for motor development as well as acquiring everyday social and communicative skills. We present the first part of adaptive physical education technology &ldquo;Aut Fitness&rdquo;. The technology is based on the principles of organization of motions by N.A. Bernstein, the concepts of sensory integration and sensori-motor correction. The technology provides a comprehensive curriculum for physical ability and motor skills development of a child with ASD, from the diagnostic assessment to conceptualization of a training route to be implemented in close collaboration with the parents. The theoretical and methodological support is provided together with the aims of the technology for formation of motor skill and correction of behavior typical for ASD. The specifics of motor activity disorders in children with ASD and additional factors that make it difficult to study in physical education classes are described. Targets in the areas of general development, adaptation, health, well-being and age-specific advancement are identified and described. These are the development of strength, dexterity, endurance, coordination abilities; training in breathing exercises and elements of sports games; prevention and correction of posture disorders. The stages of the implementation of programs developed using the &ldquo;Aut Fitness&rdquo; technology are described These are a system of classes aimed at the harmonious motor and communicative development of children with ASD, taking into account their level of physical fitness.</p
