We generalize several propositional preprocessing techniques to higher-order logic, building on existing first-order generalizations. These eliminate literals, clauses, or predicate symbols from the problem, with aim of making it more amenable automatic proof search. also introduce a new technique, which we call quasipure literal elimination, that strictly subsumes pure elimination. The are imp...

Hydrate plugging in gas- and oil-production transport systems has long been a critical challenge. Traditional hydrate mitigation strategies through applying chemicals thermal destabilization are costly eco-unfriendly. Passive anti-hydrate surfaces with potential to enable self-removal of hydrates desired. Surprisingly, thin onion film peeled off from an bulb scale is found have low adhesion, th...
