Canonical calculi with (n,k)-ary quantifiers [PDF]

open access: yesLogical Methods in Computer Science, 2008
Propositional canonical Gentzen-type systems, introduced in 2001 by Avron and Lev, are systems which in addition to the standard axioms and structural rules have only logical rules in which exactly one occurrence of a connective is introduced and no ...

Cut-Elimination for SBL

open access: yes, 2020
In this paper we give a terminating cut-elimination procedure for a logic calculus SBL. SBL corresponds to the second order arithmetic Pi^{1}_{2}-Separation and Bar Induction.

Linear Abelian Modal Logic

open access: yesBulletin of the Section of Logic
A many-valued modal logic, called linear abelian modal logic \(\rm {\mathbf{LK(A)}}\) is introduced as an extension of the abelian modal logic \(\rm \mathbf{K(A)}\). Abelian modal logic \(\rm \mathbf{K(A)}\) is the minimal modal extension of the logic of

Partial cut elimination for combinations of propositional multi-modal logics with past time

open access: yesLietuvos Matematikos Rinkinys, 2011
We consider combinations of nine propositional multi-modal logics with propositional discrete linear time temporal logic with past time. For these combinations, we present sound and complete Gentzen-type sequent calculi with a restricted cut rule.

On Multiplicative Linear Logic, Modality and Quantum Circuits [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2012
A logical system derived from linear logic and called QMLL is introduced and shown able to capture all unitary quantum circuits. Conversely, any proof is shown to compute, through a concrete GoI interpretation, some quantum circuits.

Composite power system reliability evaluation using modified minimal cut set approach

open access: yesAlexandria Engineering Journal, 2018
The composite power system reliability analysis is generally based on minimal path or cut enumeration, tracing of power flow paths from which the related reliability indices are calculated.

An Investigation into the Multi-Pass Radial-Mode Micro Abrasive Air Jet Turning of Fused-Silica Rods

open access: yesMachines, 2023
With the increased requirement of miniaturization structures on hard and brittle substrates, micro abrasive air jet turning technology has become a promising machining technology for manufacturing miniaturization structures.

Structural cut elimination

open access: yesProceedings of Tenth Annual IEEE Symposium on Logic in Computer Science, 2000
Presents new proofs of cut elimination for intuitionistic, classical and linear sequent calculi. In all cases, the proofs proceed by three nested structural inductions, avoiding the explicit use of multi-sets and termination measures on sequent derivations.

On the non-confluence of cut-elimination

open access: yesThe Journal of Symbolic Logic, 2011
AbstractWe study cut-elimination in first-order classical logic. We construct a sequence of polynomial-length proofs having a non-elementary number of different cut-free normal forms. These normal forms are different in a strong sense: they not only represent different Herbrand-disjunctions but also differ in their prepositional structure.This result ...

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system

open access: yesFEBS Letters, EarlyView.
Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.
