Negative Spectrum of Non-local Operators with Periodic Potential

The paper deals with spectral analysis of non-local operators arising in population dynamics models. We consider negative periodic perturbations of non-local operators of the convolution type. Such operators describe evolutions of the first correlation function in the stochastic...

Thematic Structure of Clinical Rehabilitation Research in the Early Post-Pandemic Period: An LDA-Based Analysis of Publications from 2022 to 2025

Background/Objective: Recent advances in scientometric topic modeling have enhanced the capacity to rapidly assess evolving research priorities. This study aimed to characterize the thematic reorganization of clinical rehabilitation research during the early post-pandemic period...

Multiple spiking functionalities in annealing-optimized Ag/Hf0.5Zr0.5O2-based memristive neurons

Rapid progress of artificial neural network applications in recent years has led to the issue of unprecedented energy consumption. It can be solved by the implementation of energy-efficient hardware based on non-von Neumann architectures, which requires the development of electro...

From volatile to nonvolatile resistive switching in a ferroelectric second-order memristor

Ferroelectric memristors are promising candidates for neuromorphic computing, yet their practical application is hindered by the trade-off between the volatile synaptic plasticity required for learning and the nonvolatile retention needed for long-term data storage. Here, we demo...

Conformal blocks of Wess-Zumino-Witten model from its free-field representation

A bstract A powerful approach to the celebrated Wess-Zumino-Witten (WZW) model is provided by its free-field realization. However, explicit calculations of conformal blocks are not described in the literature in full detail. We begin this study with the simplest cases of the $$ \...

Systemic induced plant resistance genes expression in winter wheat under treatment with antagonistic bacteria of Fusarium sp .

Fusarium oxysporum and Fusarium graminearum are pathogenic fungi responsible for diseases in wheat, leading to mycotoxins accumulation in wheat grains and significant yield losses. The use of plant growth-promoting rhizobacteria (PGPR) represents a promising, sustainable biocontr...

Beyond majority voting: a new framework for evaluating AI diagnostic systems against expert consensus

The integration of artificial intelligence (AI) into medical diagnostic workflows requires robust and consistent evaluation methods to ensure reliability, clinical relevance, and the inherent variability in expert judgments. Traditional metrics like precision and recall often fai...

Metaphor in population-based AI

Abstract English serves as the primary source language for Artificial Intelligence terminology, playing a pivotal role in shaping the metaphorical expressions that underpin specialized lexicons and facilitate knowledge transfer. This study investigates the patterns of metaphorica...
