The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

We introduce a simple model incorporating dynamically accessible free volume regions as a key driver of polymer mobility, effectively capturing the (anti-)plasticization of elastic properties. We show that accessibility of free volume regions is enabled by connectivity of additive-accessible volume regions.

C2weakest assumption

That the decomposition of elastic moduli into polymer-polymer and polymer-water interaction contributions from MD simulations accurately reflects real molecular behavior, and that the introduced free volume model captures this competition without post-hoc adjustments or unstated fitting.

C3one line summary

A model of dynamically accessible free volume regions connected through additive-accessible volumes explains the antiplasticization followed by plasticization of elastic properties in chitosan-water mixtures.
