Distributed knowledge execution and entrepreneurial adaptability: extending knowledge management into autonomous digital ecosystems

Purpose This study aims to examine how distributed intelligence capabilities function as knowledge management mechanisms that support entrepreneurial innovation and strategic scalability in distributed digital ecosystems. Specifically, the study investigates how augmented intelli...

A multiplicative additive bias variational framework for accurate and interpretable brain MRI segmentation in cloud-based medical imaging systems

Abstract Accurate brain magnetic resonance imaging (MRI) segmentation remains challenging due to intensity inhomogeneity, acquisition-related bias fields, and ambiguous tissue boundaries. To address these challenges, a Multiplicative–Additive Bias Single-Function Dual-Level-Set (...

Influence of total occlusal convergence and auxiliary retentive features on regional marginal discrepancy in milled and 3D-printed short provisional crowns—an in-vitro study

This in-vitro study evaluated the influence of total occlusal convergence (TOC) (10°/20°) and auxiliary retentive features (ARF) (groove, proximal box) on regional marginal discrepancy in milled (CopraTemp PMMA) and 3D-printed (Asiga Dentatooth) short (3 mm) provisional crowns (P...

Bayesian Inference via Markov Iterative Methods for Generalized Progressive Hybrid Unit Bilal Censoring and Its Applications to Thermodynamics and Meteorology

The increasing availability of bounded lifetime observations in different disciplines has intensified the demand for flexible models capable of accommodating complex failure mechanisms. Motivated by this need, a comprehensive inferential framework is developed for the unit Bilal...

Multistream Vision Transformer Fusion with Stain-Physics Priors for Reliable Colorectal Histopathology Classification

Discriminating hyperplastic polyps from sessile serrated adenomas (SSA) in colorectal histopathology is clinically consequential, with documented interpathologist agreement of only κ≈0.56. Existing deep‑learning approaches treat hematoxylin and eosin (H&E) images as entangled RGB...

Femoral malrotation and patellofemoral osteoarthritis: cadaveric study

BACKGROUND: Femoral rotational alignment has been proposed as one factor that may influence patellar tracking and the distribution of patellofemoral joint loading. The present study explored whether characteristic patterns of patellar facet degeneration coexist with abnormally hi...

Green synthesis of Ni-doped ZnO nanoparticles using Salvia hispanica and their antibacterial, anticancer and anti-virulence activities

An environmentally benign approach was employed to synthesize nickel-doped zinc oxide (Ni–ZnO) nanoparticles employing Salvia hispanica extract as a biologically derived reductant and capping material. Phytochemical profiling confirmed the abundance of phenolic and flavonoid comp...

Vardenafil Alleviates Doxorubicin-Induced Cardiotoxicity Associated with Restoration of the AMPK/SIRT1 Signaling Pathway

Background: Doxorubicin-induced cardiotoxicity (DIC) is a major limitation of anthracycline chemotherapy and is characterized by oxidative stress, apoptosis, and myocardial remodeling. Dysregulation of AMP-activated protein kinase (AMPK) and its downstream effector sirtuin-1 (SIR...
