Broadway is the most famous street of New York City. It follows the island of Manhattan along its whole length and through many of its vernacular regions. Field research of functional, social-economic, architectural and mental differentiation of the street from Bowling Green to 142 Street in Spanish Harlem shaped the methods of linear zoning and revealed 16 unique regions in the researched segment. These regions turned out to be functional, but their borders and composition are based on the vernacular regions of Manhattan. It appears that Broadway, as a major trade and social thruway, forms the surrounding urban landscape. But the role of vernacular regions, through which street passes, remains important and sometimes even crucial.
Verification of the PREFAB database containing golden standard protein alignments was performed. It has revealed a significant number of differences between the sequences from PREFAB and PDB databases. It was shown that, compared with the sequences given in the PDB, 575 alignments referred to a sequence with a gap; such alignments were excluded. Furthermore, compared with the PDB sequences, single substitutions or insertions were found for 440 amino acid sequences from PREFAB; these sequences were edited. SCOP domain analysis has shown that only 502 alignments in the resulting set contain sequences from the same family. Finally, eliminating duplicates, we have created a new golden standard alignment database PREFAB P based on PREFAB; the PREFAB P database contains 581 alignments.
Housing construction in Moscow agglomeration is a key mechanism stimulating migration inflow because it forms a downward pressure on housing prices, which are the most important barrier for migration. Positive feedback between extensive way of development of the Moscow agglomeration and migration inflow into the capital region stimulates hyperconcentration of the population and economic activity. Theoretical analysis shows that there is equilibrium between housing construction and migration inflow to the Moscow region. According to our estimates, in the 2000-s the relation of migration inflow to housing construction volume (capability of the Moscow agglomeration to accumulate migration) has halved in comparison to the 1990s. Mathematical modeling and empirical data show that this shift was determined by the increase in natural rent distributed in Russia and in agglomeration economies in other major cities of the country. Especially favorable for migration inflow is oil-spot-style extensive way of development of the agglomeration due to the dominance of large greenfield projects of affordable housing in the 30-km zone outside the Moscow Ring Road in housing construction. It is shown that the development of this zone is a key regulator of the migration balance at the national level. Extensive way of development is subsidized by the government through multiple channels, primarily investments in transport infrastructure, what contradicts official goals of the regional policy and the government efforts to mitigate interregional inequality through the fiscal redistribution.
The generalized Wiedemann-Franz law for a nonisothermal quasi-neutral plasma with developedion-acoustic turbulence and Coulomb collisions has been proven. The results obtained are used to explain the anomalously low thermal conductivity in the chromosphere-corona transition region of the solar atmosphere. Model temperature distributions in the lower corona and the transition region that correspond to well-known experimental data have been determined. The results obtained are useful for explaining the abrupt change in turbulent-plasma temperature at distances smaller than the particle mean free path.
The influence of nonlinear interaction of oppositely directed nonlinear waves in a shallow basin is studied theoretically and numerically within the nonlinear theory of shallow water. It is shown that this interaction leads to a change in the phase of propagation of the main wave, which is forced to propagate along the flow induced by the oncoming wave. The estimates of the undisturbed wave height at the time of interaction agree with the theoretical predictions. The phase shift during the interaction of undisturbed waves is sufficiently small, but becomes noticeable in the case of the propagation of breaking waves.
The mathematical modelling is performed to study the effect of the permeability of the Casparian bands to water and solutes on the formation of the root pressure. It is shown that the pressure in the xylem vessels which stops the flow across a root cut (root pressure) decreases with increase in the permeability of the Casparian bands to solutes at a fixed hydraulic conductivity. However, if the Casparian bands are permeable to water alone and impermeable to solutes, then changes in the root pressure changes are not observed.
The article analyses the effects of new transport infrastructure on transport systems of the 2018 FIFA World Cup host cities. The choice of cities is based on the scale of planned transport infrastructure – Saransk, Kaliningrad and Ekaterinburg experienced substantial interventions. Analysis is conducted using open spatial data on population and street networks. All interventions in transport infrastructure were evaluated in terms of their effectiveness and usefulness for the cities after the 2018 FIFA World Cup – scale of improvements in street network connectivity and accessibility of key places in the cities. We identified that investments into new transport infrastructure of Saransk seems to be the most effective in terms of future use. We demonstrated the feasibility of conducting such analysis using only open data, but also identified some issues and pitfalls.
The article questions the thesis of the low migration activity of the Russian population in the way of in-country resettlement in comparison with foreign countries. Reasons prevented a direct comparison of data on internal migration in Russia and other countries had been analyzed. Mainly, they were related to differences in the size of units of administrative and territorial division and diversity in approaches to the definition of in-country migration. Based on the migration data of 2013-2014. it was concluded that Russia and several countries with advanced migration statistics differ substantially. Russia lags behind the leading countries about twice. However, it is superior to other countries, especially in eastern and southern Europe, in terms of migration intensity.
Analysis of internal migration flows by age shows that, in general, Russia and other developed countries have similar age migration profiles. in contrast to other comparable countries, Russian peak at the age of 15-29 years is more clearly defined and biased to the youngest age. It is related to a greater compactness in the life path of socio-demographic events, which leads to migration movements. Differences between the age profile of migration in Russia and other countries in the rest of the age groups do not correspond to our expectations, they are not great.
