Предлагается методика символического моделирования общественного развития на основе математической комбинаторики, обращения к теории эволюции, отбору вариантов интегральных моделей.
The daily-case numbers of Covid-19 were studied and an oscillatory pattern in the numbers was identified. And this oscillatory nature has been present throughout the pandemic data. Although the US has had four waves of varying amplitude,... more
The safety problem in structural engineering can be treated more rationally with probabilistic methods. These methods provide basic tools for evaluating structural safety quantitatively. Uncertainties in loads, material properties, and... more
Abstract In this invited lecture the biomechanical analysis of tactical tools utilized by top athletes in high level competition is presented. In the first part, the lecture starts with a very short summary of the researches carried... more
Flupyradifurone (FPF, Sivanto®) is a new butenolide insecticide that, like the neonicotinoids, is a systemic nicotinic acetylcholine agonist (nAChR). However, FPF is considered bee-safe (according to standard Risk Assessment tests), and... more

Статья посвящена символическому моделированию общественно-политических процессов в России (прежде всего на основе государственной символики – флага, герба, гимна, президента) в период с 1985 по 2008 гг. Выделяя символические элементы... more
Los efectos sociales de la materialización de la Carta de Atenas (1933) durante la posguerra fueron cuestionados por la siguiente generación de arquitectos, planteando conceptos como asociación, movilidad, identidad o crecimiento,... more
Using fundamental relationships in mathematics such as necessary conditions to root out fundamental relationships in mathematics such as foundations of set theory.
Обосновывается методика создания символических моделей общественного развития на основе математической комбинаторики, обращения к теории эволюции, отбору вариантов. Выбор ограниченного числа доминантных и недоминантных символических... more
En el aprendizaje de las matematicas se suelen observar problemas debido a que los conceptos involucrados resultan a menudo complejos por su alto nivel de abstraccion. Se han detectado problemas en el aprendizaje de los conceptos... more
In this paper, a semantic classification for Persian adjectival preverbs based on Conceptual Metaphor Theory is presented: adjectival preverbs that demonstrate metaphorical shift and adjectival preverbs which lack metaphorical shift. The... more

At the initial stage of language learning, when all the attention is focused on the use of phrases for communication, a particular approach is needed in order to solve one problem: what dosage of theoretical material of grammar is... more
We investigate the use of elastic hierarchies for representing trees, where a single graphical depiction uses a hybrid mixture, or" interleaving", of more basic forms at different nodes of the tree. In particular, we explore... more
Despite of many conjectures and partial results on three colorable planar graphs nal clue has not yet been discovered. Steinberg's three coloring conjecture which asserts that all planar graphs without four and ve cycles are 3-colorable... more
During a survey of the freshwater littoral diatom flora from lakes and ponds in the region of Petuniabukta on Spitsbergen (Svalbard Archipelago, High Arctic region), a new Achnanthidium species, A. petuniabuktianum sp. nov., has been... more
