Black phosphorus quantum dots for resistome mitigation: Mechanistic insights and rational engineering

The emergence of antibiotic resistance as a global environmental challenge has intensified the need for advanced strategies capable of addressing antibiotic contamination while reducing the environmental drivers of resistance dissemination. Although black phosphorus quantum dot (...

Probing dark matter and phantom field effects on neutrino oscillations around black holes

Abstract This study investigates how dark matter in the background of the phantom field (DMPF) near a black hole influences neutrino flavor oscillations using a two-flavor model. It is found that gravitational effects are cancelled for radially moving neutrinos, causing the oscil...

ABSTRACT The design and development of high‐performance electrocatalytic systems featuring multiple functionalities, excellent recyclability, and reusability constitute a vital and essential advancement in the field of green chemistry. Such innovative approaches significantly mit...

Explainable AI-assisted sustainable performance optimization of Nano-enhanced rapeseed oil blends in ci engines for optimized engine operation

This study investigates the influence of advanced fuel injection timing on the performance, combustion, and emission characteristics of a compression ignition engine fueled with a rapeseed oil emulsion–pentanol blend (70D25GS5P) supplemented with 150 ppm TiO₂ nanoparticles. Exper...

Circular-orbit dynamics and QPO constraints in static Einstein–scalar–Gauss–Bonnet black holes

Abstract Einstein–scalar–Gauss–Bonnet (EsGB) gravity provides a physically motivated framework for testing strong-field deviations from the Schwarzschild geometry through scalar hair. We study neutral-particle circular motion and high-frequency quasi-periodic oscillations (HF-QPO...

ELECTRONIC EVIDENCE IN CRIMINAL JUSTICE: CHALLENGES OF AUTHENTICITY AND ADMISSIBILITY

This article studies the problems of authenticity and admissibility of electronic evidence in criminal justice. Because digital technology is now used everywhere, electronic data such as emails, social media messages, bank records and video surveillance footage are increasingly u...

Energy extraction from a rotating Buchdahl star via magnetic reconnection

Abstract In this work, we investigate the magnetic reconnection (MR) process as a mechanism for energy extraction from a rapidly rotating Buchdahl star (BS), one of the most compact horizonless objects that can, in principle, possess a spin parameter exceeding the extremal limit...

Stress Management as a Systemic Process of Psychological Regulation

The aim of this study was to develop an integrated theoretical model of stress management based on a multi-level analysis of the mechanisms of psychological regulation under stress conditions. The research employed a systemic approach and utilised methods of scientific literature...

Hepatitis B and D burden in Uzbekistan: comprehensive analysis of seroprevalence and risk correlates from a countrywide study

Abstract Background Uzbekistan faces a substantial burden of hepatitis B and D virus (HBV and HDV) infections despite implementing universal hepatitis B vaccination in 1998. Regional variation in disease distribution and contemporary transmission dynamics remain inadequately char...

Wild Edible Morels in Uzbekistan: Ethnomycological Knowledge and Seasonal Use Across Wooded and Dryland Habitats

Wild edible morels are among the most recognisable spring fungi in Uzbekistan, yet their species‐level identity, locality‐based distribution and ethnomycological significance remain incompletely documented. This review synthesises evidence concerning Morchella esculenta (L.) Pers...

Multi-Target Modulation of Interconnected Pathogenetic Pathways by Natural Bioactive Compounds in Endometriosis

Background: Endometriosis is a chronic estrogen-dependent disease characterized by the presence of endometrial-like tissue outside the uterine cavity. Its pathogenesis involves interactions between inflammatory, angiogenic, hormonal, oxidative stress-related, and cell survival-as...

Multivariate characterization of foliar morpho-anatomical traits supporting adaptive trends and taxonomic resolution in halophytic grasses

Leaf morphology and epidermal traits of 15 salt-tolerant grasses belonging to 10 genera from the Bahadur Khel Salt Range were examined using a microscopic technique for the first time. Eight qualitative characters (epidermal cell shape, anticlinal wall patterns, type of stomata a...

Explainable Multi-Objective Quantum-Inspired Fuzzy Optimization of Rule Bases for Scalable Load Balancing in Multi-Factor Computing Environments

The rapid growth of cloud and distributed computing systems has increased the complexity of real-time request distribution under dynamic and multi-factor conditions. In such environments, load-balancing decisions must simultaneously consider uncertain and interdependent parameter...
