Hamiltonian cycles on bicolored random planar maps
We study the statistics of Hamiltonian cycles on various families of bicolored random planar maps (with the spherical topology). These families fall into two groups corresponding to two distinct universality classes with respective central charges c=−1 ...

The COVID-19 pandemic has affected the mental health of regular basic education teachers. Despite the fact that in recent months the number of infections has decreased significantly, the return to face-to-face classes is of great concern to teachers due ...

Variations of Landau’s theorem for p-regular and p-singular conjugacy classes [PDF]
The well-known Landau's theorem states that, for any positive integer $k$, there are finitely many isomorphism classes of finite groups with exactly $k$ (conjugacy) classes. We study variations of this theorem for $p$-regular classes as well as $p$-singular classes.

Enjoyment is one of the most important factors for the maintenance of regular physical activity. The present study investigated if cooperative games in physical education classes (grades 6-9) can increase students' enjoyment of physical activity.

School-based programmes have shown promising results in the reduction of aggressive behaviour, but the effectiveness of physical activity modalities among adolescents remains to be determined.

$$L^p$$ Regularity Estimates for a Class of Integral Operators with Fold Blowdown Singularities [PDF]
We prove sharp $L^p$ regularity results for a class of generalized Radon transforms for families of curves in a three-dimensional manifold associated to a canonical relation with fold and blowdown singularities. The proof relies on decoupling inequalities by Wolff and Bourgain-Demeter for plate decompositions of thin neighborhoods of cones and $L^2 ...

Two Classes of Linear Codes From Weil Sums
In this article, we consider two classes of $p$ -ary linear codes. This article is a generalization of the recent construction methods given by Jian, Lin and Feng (2019).

A Unified View of Graph Regularity via Matrix Decompositions
We prove algorithmic weak and \Szemeredi{} regularity lemmas for several classes of sparse graphs in the literature, for which only weak regularity lemmas were previously known.

The aim of the study was to investigate the effects of eight weeks of regular physical education classes supplemented with high intensity interval cycle exercise (HIIE) or continuous cycle exercises of moderate intensity (CME).

The Prevalence of Myopia in Schoolchildren in Some Regions of Russia
The frequency of myopia reached 26 % among of school graduates in 2000. In case of graduates from gymnasiums and lyceums — 50 %. The share of severe form of myopia 10–12 %. A pilot study was conducted.
