Red Pigments in the Bronze Age Burials in the North Caucasus: Complex Analysis for Identification of Pyroprocessing of Iron Minerals

open access: yesВестник Волгоградского государственного университета. Серия 4. История, регионоведение, международные отношения, 2018
Ochre is a natural pigment of yellow or red color, mainly consisting of iron minerals. Along with determining the origin of mineral dyes, one of the main problems of studying natural pigments in archaeology is identifying the origin of the so-called “red”

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Application of upper estimates for products of inner radii to distortion theorems for univalent functions

open access: yesМатематичні Студії, 2023
In 1934 Lavrentiev solved the problem of maximum of product of conformal radii of two non-overlapping simply connected domains. In the case of three or more points, many authors considered estimates of a more general Mobius invariant of the form $$ T_{n}:

Intelligent Agents in Co-Evolving Knowledge Networks

open access: yesMathematics, 2021
We extend the agent-based models for knowledge diffusion in networks, restricted to random mindless interactions and to “frozen” (static) networks, in order to take into account intelligent agents and network co-evolution.
