1. IntroductionEstablishing an efficient, reliable, and flexible maritime logistics system has been a focal point for numerous scholars, as maritime transportation plays a crucial role in global trade and supply chain networks. Within this domain, the berth allocation problem (BAP) is a key challenge, as it directly impacts the operational efficiency of ports, which are critical nodes in maritime logistics.

Mobile metal atoms underlying reactionsIn heterogeneous catalysis, it is often assumed that adsorbates have minimal effects on the bonding between surface metal atoms at low temperatures and pressures. Xu et al. used density functional theory to find conditions in which adsorbed molecules can scavenge transition metal atoms by breaking bonds at the surface.
