Maximum Entropy Reasoning via Model Counting in (Description) Logics that Count

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference
In previous work it was shown that the logic ALCME,  which extends the description logic (DL) ALC with probabilistic conditionals, has domain-lifted inference.

Unary negation [PDF]

open access: yesLogical Methods in Computer Science, 2013
We study fragments of first-order logic and of least fixed point logic that allow only unary negation: negation of formulas with at most one free variable.

Monadic Second-Order Logic and Bisimulation Invariance for Coalgebras [PDF]

open access: yes, 2015
Generalizing standard monadic second-order logic for Kripke models, we introduce monadic second-order logic interpreted over coalgebras for an arbitrary set functor.

Modal Logics with Hard Diamond-Free Fragments [PDF]

open access: yesJournal of Logic and Computation, 2015
AbstractWe investigate the complexity of modal satisfiability for a family of multi-modal logics with interdependencies among the modalities. In particular, we examine four characteristic multi-modal logics with dependencies and demonstrate that, even if we restrict the formulae to be diamond-free and to have only one propositional variable, these ...

Adding Path-Functional Dependencies to the Guarded Two-Variable Fragment with Counting [PDF]

open access: yesLogical Methods in Computer Science, 2017
The satisfiability and finite satisfiability problems for the two-variable guarded fragment of first-order logic with counting quantifiers, a database, and path-functional dependencies are both ExpTime-complete.

A Variant of Material Connexive Logic

open access: yesBulletin of the Section of Logic, 2021
The relationship between formal (standard) logic and informal (common-sense, everyday) reasoning has always been a hot topic. In this paper, we propose another possible way to bring it up inspired by connexive logic.

A Logic for True Concurrency [PDF]

open access: yes, 2014
We propose a logic for true concurrency whose formulae predicate about events in computations and their causal dependencies. The induced logical equivalence is hereditary history preserving bisimilarity, and fragments of the logic can be identified which

An Efficient Algorithm for Monitoring Practical TPTL Specifications

open access: yes, 2016
We provide a dynamic programming algorithm for the monitoring of a fragment of Timed Propositional Temporal Logic (TPTL) specifications. This fragment of TPTL, which is more expressive than Metric Temporal Logic, is characterized by independent time ...

Languages of Dot-depth One over Infinite Words [PDF]

open access: yes, 2011
Over finite words, languages of dot-depth one are expressively complete for alternation-free first-order logic. This fragment is also known as the Boolean closure of existential first-order logic.

An upstream open reading frame regulates expression of the mitochondrial protein Slm35 and mitophagy flux

open access: yesFEBS Letters, EarlyView.
This study reveals how the mitochondrial protein Slm35 is regulated in Saccharomyces cerevisiae. The authors identify stress‐responsive DNA elements and two upstream open reading frames (uORFs) in the 5′ untranslated region of SLM35. One uORF restricts translation, and its mutation increases Slm35 protein levels and mitophagy.
