Development of a technical condition assessment algorithm for complex systems based on probabilistic failure estimation

open access: yesÌнформаційні технології та компʼютерна інженерія
The study aimed to provide a theoretical justification for the use of chaotic dynamical systems to enhance the strength of cryptographic keys. The research methodology was based on theoretical, comparative and critical analysis of scientific sources to ...

Simulating infrastructure networks in the Yangtze River Delta (China) using generative urban network models

open access: yesBelgeo, 2016
This paper explores the urban-geographical potential of simulation approaches combining spatial and topological processes. Drawing on Vértes et al.'s (2012) economical clustering model, we propose a generative network model integrating factors captured ...

Anselm's Temporal‐Ontological Proof

open access: yesNoûs, Volume 60, Issue 3, Page 645-660, September 2026.
ABSTRACT In his Reply to Gaunilo, Anselm presented two additional arguments for the existence of God beyond those that appear in the Proslogion. In “The Logical Structure of Anselm's Argument,” Robert M. Adams isolates each. One, he develops into a modal ontological argument along the lines of other 20th century ontological arguments (e.g., those of ...

Characterization of topological phase transitions via topological properties of transition points [PDF]

open access: yesPhysical Review B, 2015
We study topological properties of phase transition points of topological quantum phase transitions by assigning a topological invariant defined on a closed circle or surface surrounding the phase transition point in the parameter space of momentum and transition driving parameter.

Surface subgroups for cocompact lattices of isometries of H2n$\mathbb {H}^{2n}$

open access: yesJournal of Topology, Volume 19, Issue 3, September 2026.
Abstract We prove the existence of surface subgroups within any cocompact lattice Γ$\Gamma$ in SO(2n,1)$\mathrm{SO}(2n,1)$ for n⩾2$n\geqslant 2$. This result addresses the cases missing from the work of Hamenstädt in 2015, who constructed surface subgroups in cocompact lattices for all other rank‐1 simple Lie groups of noncompact type.

Photoinduced Topological Phase Transitions in Topological Magnon Insulators [PDF]

open access: yesScientific Reports, 2018
AbstractTopological magnon insulators are the bosonic analogs of electronic topological insulators. They are manifested in magnetic materials with topologically nontrivial magnon bands as realized experimentally in a quasi-two-dimensional (quasi-2D) kagomé ferromagnet Cu(1–3, bdc), and they also possess protected magnon edge modes.

On Local Aspects of Topological Transitivity and Weak Mixing in Set-Valued Discrete Systems

open access: yesDiscrete Dynamics in Nature and Society, 2013
Blanchard and Huang introduced the notion of weakly mixing subset, and Oprocha and Zhang gave the concept of transitive subset and studied its basic properties. In this paper our main goal is to discuss the weakly mixing subsets and transitive subsets in

Microbiological Mechanisms of Sand‐Mixed Soil Improvement in Continuously Cropped Soil

open access: yesLand Degradation &Development, Volume 37, Issue 13, Page 9390-9405, 15 August 2026.
ABSTRACT Sand‐mix soil is a widely adopted method for soil improvement in agricultural production. However, beyond the evident enhancement of physical structure, the mechanisms by which sand‐mix soil promotes crop root growth by influencing soil physicochemical properties and microbial communities remain insufficiently understood.

Characterization of neighborhood operators based on neighborhood relationships

open access: yesJournal of Intelligent Systems
Neighborhood relationships play a pivotal role in rough set theory, addressing the limitations of equivalence relations. This article focuses on defining upper and lower approximation operators using neighborhood relationships and exploring their ...
