Differential Game Analysis of Cross-Border E-Commerce Supply Chains Under Dual Trade Barriers

This study examines a two-echelon cross-border e-commerce (CBEC) supply chain under the joint constraints of technical barriers to trade (TBTs) and tariffs. To capture the cumulative nature of foreign-market access, the degree of trade barrier breakthrough is modeled as a continu...

Enantioselective Convergent Synthesis of Heterohelicenes via Copper-Catalyzed Propargylic Annulation/Acid-Promoted Aromatization

Abstract Heterohelicenes combine helical chirality with tunable electronic properties, making them attractive for applications in chiral materials and optoelectronics. However, their enantioselective synthesis, particularly for five-membered heterohelicenes, remains a long-standi...
