Spatial log-periodicity of symmetric first-passage times in finite Sierpinski graphs: geometric frequency, stability, and extrapolation

We investigate how the mean time for a random walker to first reach a target depends on source–target separation in three finite Sierpinski graph families: planar, tetrahedral, and scale-three planar. After removing the leading growth with distance, we examine small oscillations...

Macroecological invisibility in apple snails (Gastropoda: Ampullariidae): uneven occurrence and molecular coverage across public repositories

Abstract Apple snails (Ampullariidae) are freshwater gastropods of ecological and economic importance, but their digital representation remains uneven across taxa, regions and data types. Using a 171-species taxonomic reference, we integrated global occurrence and molecular data...

Modulation of Advanced Glycation End Products and Oxidative Stress by Hesperetin-7-O-Glucoside and Diosmetin-7-O-Glucoside Complexed with Cyclodextrins

Background/Objectives: Chronic complications of diabetes mellitus are closely associated with increased oxidative stress and the formation of advanced glycation end products (AGEs). This study aimed to investigate the antioxidant and antiglycation potential of hesperetin-7-O-gluc...
