Topological entropy and blocking cost for geodesics in riemannian manifolds
For a pair of points in a compact, riemannian manifold let
(resp. ) be the number of geodesic segments with length
joining these points (resp. the minimal number of point obstacles
needed to block them). We study relationships between the growth rates of
and as . We derive lower bounds on

strengthens the results of Burns-Gutkin \cite{BG06} and Lafont-Schmidt
\cite{LS}. For instance, by \cite{BG06,LS}, implies that is
unbounded; we show that grows exponentially, with the rate at least

Monocyte response in myocardial infarction in patients with type 2 diabetes
Aim. To reveal the features of monocyte response in myocardial infarction (MI) in patients with type 2 diabetes (T2D).Material and methods. The study included 121 patients with MI and T2D as follows: 76 — with target glycated hemoglobin (HbA1c), 45 — with elevated HbA1c values. In addition to the standard examination, all patients underwent a blood test for HbA1c on day 1 of MI, while on days 1, 3, 5, and 12±1, monocyte subpopulations were assessed by flow cytometry.Results. Patients with target HbA1c were older than patients with elevated HbA1c levels. In the group with target HbA1c, the number of CD16(+) monocytes on the 1st day of MI was significantly higher: 61,38 (39,2; 100,08) cells/µl vs 35,7 (28,98; 40,33) cells/µl, p=0,03; on the 3rd day of MI, the number of "intermediate" CD14(+)CD16(+) monocytes was higher: 74,82 (71,78; 83,2) cells/µl vs 25,90 (14,04; 57,12) cells/µl, p=0,03, while the CD16(-) to CD16(+) monocyte ratio on the 3rd day of MI was lower: 8,32 (6 ,87; 10,03) vs 10,81 (8,90; 21,10), p=0,04. At the same time, in the group of patients with target HbA1c values, the level of CD16(+) monocytes on the 3rd day of MI was significantly higher in patients aged <71 years compared with patients ≥71 years: 104,55 (63,64; 149,7) cells/µl vs 55,20 (36,92; 76,59) cells/µl, p=0,03.Conclusion. In patients with T2D and target HbA1c values, compared with patients with elevated HbA1c, the inflammatory response in MI is associated with higher levels of CD16(+) monocytes on days 1 and 3 of MI, which is more typical for people aged <71 years
Semiconducting end-perfluorinated P3HT–fullerenic hybrids as potential additives for P3HT/IC70BA blends
An efficient route to synthesise hybrid polymers consisting of a semiconducting polymer and a fullerene unit, for BHJ OPV devices is presented herein. The synthetic procedure is based on the in situ functionalisation of regioregular polythiophenes of various molecular weights with perfluorophenyl moieties at the ω end position of the polymeric chains, after the GRIM polymerisation reaction. Each of the perfluorophenyl moieties is then decorated with an azide group, and employed in a [3+2] cycloaddition reaction with fullerene species, i.e. C70 or IC70MA, yielding P3HT-fullerene hybrids covalently linked via aziridine bridges. The effectiveness of the purification procedures of the above organic and hybrid materials were evaluated by extended spectroscopic and chromatographic methods. The optical and electrochemical characterisation of the resulting hybrid structures revealed that the unique optoelectronic properties of the P3HT polymers are retained in the hybrid materials. Whereas the morphological properties are largely affected by the introduction of the C70 and IC70MA fullerenes. The enhanced and tunable nanophase separation observed in the polymerfullerene hybrid films coupled with their excellent optoelectronic properties makes them exciting potential polymeric additives for the P3HT:IC70BA active blends

Long-term management of patients with epilepsy. Organization of a service in the Tyumen Region
Epilepsy is a chronic brain disease that requires a long-term or lifelong follow-up of patients. The factors that influence the outcome of therapy are various; moreover, the key factors of them are the organization of care and the mode of patient follow-up. The necessity of optimizing the specialized health care to this category of patients stems from the poorer quality of life in the patients and their families and from the more frequentdevelopment of mental disorders and drug-resistant forms of the disease during ineffective therapy. These and other issues are considered in this paper with emphasis on the specific area – the south of the Tyumen Region. This underlines the importance of setting up not only highlevel epileptologic centers, but also a whole network that provides access to specialized epileptologic care. It seems today that it is more appropriate to solve problems in the organization of management for epileptic patients at the level of an administrative region, for this state structure has all necessary conditions for rapidly and rationally implementing the most successful developments of specialized care to the population
A comparison of the characteristics of extreme drought during the late 20 th and early 21st centuries over Eurasia and North America
The atmospheric general circulation character during summer droughts over Eastern Europe / Western Russia and North America from 1970-2020 is examined here. A criterion to examine atmospheric drought events encompassed the summer season was used to determine which years were driest using precipitation, evaporation, and areal coverage. The relationship between drought and atmospheric character using the Dzerzeevsky climatic classification scheme, atmospheric blocking, teleconnections, and information entropy are used to study the atmospheric dynamic
