Whose Turn, Not Who's Best: Round-Robin Rotation Over A Boolean Liveness Predicate For Unranked Local Business Discovery, Thon Ly Sep 2026

Whose Turn, Not Who's Best: Round-Robin Rotation Over A Boolean Liveness Predicate For Unranked Local Business Discovery, Thon Ly

Defensive Publications Series

We specify an unranked local-business discovery system in which candidates are ordered by a publicly verifiable round-robin rotation (algorithm, per-cycle seed and recomputation tool published) and admitted by a boolean activity predicate instead of a ranking score. Admission asks only whether a participant's account balance has returned to zero within one published, global time window; amplitude and volume are excluded, so admission is a rate that cannot be accumulated or purchased. The discovery turn belongs to the payer, not the merchant: candidates are presented when a user spends from a forward-only, locality-restricted gratuity account, so the system has no merchant-facing …

Phosphoric Acid-Mediated Regeneration Of Sugarcane Bagasse Cellulose-Rich Fraction For Enzymatic Production Of Water-Soluble Cellulosic Oligomers, Chiou-Yeong Saw, David Agus Setiawan Wibisono, Tsung-Yen Wu, Yung Chang, Chi-Fai Chau

Journal of Food and Drug Analysis

An integrated strategy was developed to promote conversion of a sugarcane bagasse cellulose-rich fraction into water-soluble cellulosic oligomers (WCOs) through phosphoric acid-mediated regeneration and enzymatic hydrolysis. Alkaline pretreatment on sugarcane bagasse powder increased glucan content from 57.6 to 93.4 g/100 g sample and lowered Klason lignin to 6.1 g/100 g sample. Phosphoric acid-mediated regeneration was subsequently capable of reorganizing the structure of cellulose from sugarcane bagasse, resulting in a decrease of crystallinity from 72.9 to 64.0% and introducing cellulose II-like features. The hydration state of regenerated cellulose strongly influenced hydrolysis performance, as the hydrated form showed significantly higher solubilization (810.4 …
