Sharpened lower bounds for cut elimination [PDF]

open access: yes, 2010
We present sharpened lower bounds on the size of cut free proofs for first-order logic. Prior lower bounds for eliminating cuts from a proof established superexponential lower bounds as a stack of exponentials, with the height of the stack proportional ...

Multirole Logic (Extended Abstract) [PDF]

open access: yes, 2017
We identify multirole logic as a new form of logic in which conjunction/disjunction is interpreted as an ultrafilter on the power set of some underlying set (of roles) and the notion of negation is generalized to endomorphisms on this underlying set.

On Combining Intuitionistic and S4 Modal Logic

open access: yesBulletin of the Section of Logic
We address the problem of combining intuitionistic and S4 modal logic in a non-collapsing way inspired by the recent works in combining intuitionistic and classical logic.

Multirole logic and multiparty channels [PDF]

open access: yes, 2017
We identify multirole logic as a new form of logic in which conjunction/disjunction is interpreted as an ultrafilter on the power set of some underlying set (of roles), and the notion of negation is generalized to endomorphisms on this underlying set. In

Tautology Elimination, Cut Elimination, and S5

open access: yesLogic and Logical Philosophy, 2017
Tautology elimination rule was successfully applied in automated deduction and recently considered in the framework of sequent calculi where it is provably equivalent to cut rule. In this paper we focus on the advantages of proving admissibility of tautology elimination rule instead of cut for sequent calculi.

Comparison of the pharmacokinetic profiles of three triterpenoids after oral administration of a cucurbitacin tablet and nanosuspension by UHPLC-MS/MS

open access: yesFrontiers in Pharmacology
IntroductionCucurbitacin, a class of triterpenoid compounds isolated from Pedicellus Melo, possesses various biological activities and is the primary active component of cucurbitacin tablets (CUT) used to treat chronic hepatitis and primary liver cancer.
