This work continues the studies of low-threshold field electron emission from thin (6 – 10 nm) films of refractory metals (Mo or Zr) deposited on flat Si substrates. Now, we have investigated the changes in the films’ morphology induced by thermo

We present an experimental setup for the study of thermoelectric effect in point contacts between different materials and in nanostructures. Point contacts of controlled size are formed with the use of an atomic force microscope (AFM), thermopower de

This paper is devoted to the study of the dynamics of vapor bubbles during water flow boiling in a graphene-coated minichannel. Graphene was synthesized directly on the surface of the boiling surface. It was found that applying a graphene film to a c

The authors in their study examined the forms of state support implemented in the Russian Federation to increase labor force and enhance the budgetary independence of the Russian Arctic regions. They investigated the impact of state support on busine

The implementation of the Northern Sea Route Development Programme aims to increase the permanent population of the Arctic zone of Russia. This problem cannot be solved without a corresponding enhancement of the food supply of the Arctic. The importa

At present, an upward trend in the field of studying the processes of hydrogen combustion in the combustion chambers of the ground-based gas turbine power plants is obvious. The use of pure hydrogen as a fuel gas would solve the problem of environmen

As AI systems become increasingly powerful, the need for safe AI has become more pressing. Humans are an attractive model for AI safety: as the only known agents capable of general intelligence, they perform robustly even under conditions that deviat

We present a method to engineer various zero-energy localized states on disorder-free hypercube graphs. Previous works have already indicated that disorder is not essential for observing localization phenomena in noninteracting systems, with some pro

The $k$-forest problem asks to find $k$ forests in a graph $G$ maximizing the number of edges in their union. We show how to solve this problem in $O(k^3 \min\{kn, m\} \log^2 n + k \cdot{\rm MAXFLOW}(m, m) \log n)$ time, breaking the $O_k(n^{3/2})$ c

We consider two problems for a directed graph $G$, which we show to be closely related. The first one is to find $k$ edge-disjoint forests in $G$ of maximal size such that the indegree of each vertex in these forests is at most $k$. We describe a min
