Full abstraction for fair testing in CCS (expanded version) [PDF]

open access: yesLogical Methods in Computer Science, 2014
In previous work with Pous, we defined a semantics for CCS which may both be viewed as an innocent form of presheaf semantics and as a concurrent form of game semantics.

A Coinductive Reformulation of Milner's Proof System for Regular Expressions Modulo Bisimilarity [PDF]

open access: yesLogical Methods in Computer Science, 2023
Milner (1984) defined an operational semantics for regular expressions as finite-state processes. In order to axiomatize bisimilarity of regular expressions under this process semantics, he adapted Salomaa's proof system that is complete for equality of ...

Counterfactuals, counteractuals, and free choice [PDF]

open access: yes, 2021
In a recent paper, Pruss proves the validity of the rule beta-2 relative to Lewis’s semantics for counterfactuals, which is a significant step forward in the debate about the consequence argument.

A Perturbed Milne’s Quadrature Rule for n-Times Differentiable Functions with Lp-Error Estimates

open access: yesAxioms, 2023
In this work, a perturbed Milne’s quadrature rule for n-times differentiable functions with Lp-error estimates is derived. One of the most important advantages of our result is that it is verified for p-variation and Lipschitz functions.

The Structural Rule Distinguishing a Superfold: A Case Study of Ferredoxin Fold and the Reverse Ferredoxin Fold

open access: yesMolecules, 2022
Superfolds are folds commonly observed among evolutionarily unrelated multiple superfamilies of proteins. Since discovering superfolds almost two decades ago, structural rules distinguishing superfolds from the other ordinary folds have been explored but

The right superior temporal gyrus plays a role in semantic-rule learning: Evidence supporting a reinforcement learning model

open access: yesNeuroImage, 2023
In real-life communication, individuals use language that carries evident rewarding and punishing elements, such as praise and criticism. A common trend is to seek more praise while avoiding criticism.

Robustness of the -Rule for an Unreliable Single-Server Two-Class Queueing System with Constant Retrial Rates

open access: yesMathematics, 2023
We study the robustness of the cμ-rule for the optimal allocation of a resource consisting of one unreliable server to parallel queues with two different classes of customers.

Graph Based Feature Selection for Reduction of Dimensionality in Next-Generation RNA Sequencing Datasets

open access: yesAlgorithms, 2022
Analysis of high-dimensional data, with more features (p) than observations (N) (p>N), places significant demand in cost and memory computational usage attributes. Feature selection can be used to reduce the dimensionality of the data.

Structured Operational Semantics for Graph Rewriting [PDF]

open access: yesScientific Annals of Computer Science, 2012
Process calculi and graph transformation systems provide models of reactive systems with labelled transition semantics (LTS). While the semantics for process calculi is compositional, this is not the case for graph transformation systems, in general ...

Characterization of All Graphs with a Failed Skew Zero Forcing Number of 1

open access: yesMathematics, 2022
Given a graph G, the zero forcing number of G, Z(G), is the minimum cardinality of any set S of vertices of which repeated applications of the forcing rule results in all vertices being in S.
