The paper analyzes the present conditions of the Russian economy, existing and possible directions of its evolution in the context of global long-term development tendencies. Proceeding from the regularities of contemporary economic growth, the main problems and threats to the Russian economy development as well as the consequences of continuing tendencies of its structural degradation are assessed. A set of proposals for the formation of economic growth policy is substantiated. These proposals take into account the need to overcome existing disproportions and problems, possibilities of the activation of the competitive advantages and sources of growth.

The interfacial instability and intrinsic structural degradation of cathodes, which cause performance loss and even a safety hazard, are a critical challenge in Ni-rich cathodes during long-term cycling.

Abstract The basic regularities in deformation and fracture of pipe steel X65 are revealed by testing specimens from the pipe fragment cut during the repair of the “Soyuz” gas main after 30 years of operation. It is shown that the pipe steel slightly changes its properties when the gas main is operated under the influence of working stresses and environmental factors. Structural degradation and micro-defects accumulated in the pipe wall were scattered, indicating that the material retains sufficient plasticity that allows it to resist fracture processes and the nucleation of macrocracks.

AbstractNeurobiology-based interventions for mental diseases and searches for useful biomarkers of treatment response have largely failed. Clinical trials should assess interventions related to environmental and social stressors, with long-term follow-up; social rather than biological endpoints; personalized outcomes; and suitable cluster, adaptive, and n-of-1 designs. Labor, education, financial, and other social/political decisions should be evaluated for their impacts on mental disease.

AbstractRapid serial visual presentation (RSVP) of words or pictured scenes provides evidence for a large-capacity conceptual short-term memory (CSTM) that momentarily provides rich associated material from long-term memory, permitting rapid chunking (Potter 1993; 2009; 2012). In perception of scenes as well as language comprehension, we make use of knowledge that briefly exceeds the supposed limits of working memory.
