Diffusion Equation with Riemann–Liouville Derivative in the Angular Domain

This paper is concerned with a boundary value problem for a fractional-order diffusion equation involving the Riemann–Liouville fractional derivative with respect to time in an angular domain. The distinctive feature of the formulation is that the lower limit of the fractional op...

The Epoxybenzooxocine Core of Integrastatins and Analogs: A Comprehensive Review of Structure, Synthetic Approaches, and Biological Applications

Abstract Integrastatins and their biogenetic counterparts possess a rare heterotetracyclic framework containing an unprecedented [6/6/6/6]-tetracyclic skeleton and a central [3/3/1]-bicyclic ketal core with high pharmaceutical potential, particularly due to their potent anti-HIV-...

Structural Evolution of RAFT-Modified Unsaturated Polyester Copolymers: Effects of CPDT Concentration, Acidic Comonomer Structure, and Polyester Matrix Architecture

Unsaturated polyester resins (UPRs) represent challenging systems for reversible-deactivation radical polymerization (RDRP) because chain propagation, branching, and localized gelation may occur concurrently. This study systematically investigates the influence of the concentrati...

Anti-Biofilm Activity of (+)-Endo-Borneol Against Streptococcus mutans: Experimental Evaluation, Virulence Gene Expression Analysis, and Molecular Docking

Streptococcus mutans is the primary etiological agent of dental caries due to its ability to form acidogenic biofilms on tooth surfaces. Natural monoterpenes have attracted considerable interest as potential antibiofilm agents for oral healthcare. The present study investigated t...
