Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

open access: yesJournal of Combinatorial Designs, EarlyView.
ABSTRACT A Hamming shell construction is a two‐level array obtained by taking every binary vector of a given Hamming weight a prescribed number of times, for each weight in turn. Such arrays are invariant under all permutations of the factors, and they are strength‐two orthogonal arrays exactly when the multiplicities satisfy three linear constraints ...

Transdiagnostic and symptom‐domain associations between mental illnesses and future self‐connectedness versus future self‐valence

open access: yesJCPP Advances, EarlyView.
Abstract Background Future time perspective dimensions have been linked to various mental illnesses. Given the tendency for mental illnesses to co‐occur, it is necessary to disentangle associations between future‐oriented constructs and shared versus symptom‐domain‐specific psychopathology.

A Structural Description of Zykov and Blanche Descartes Graphs

open access: yesJournal of Graph Theory, EarlyView.
ABSTRACT Around 1950, Zykov and Blanche Descartes proposed the two first explicit constructions of triangle‐free graphs with arbitrarily large chromatic number. We define a Zykov (resp. Blanche Descartes) graph as any induced subgraph of a graph created using Zykov's construction (resp. Blanche Descartes's).

Inter‐Group Agreement in Chest Radiographic Quality Assessment: Comparing Final‐Year Students and Experienced Radiographers Across Three Quality Assessment Domains During the COVID‐19 Pandemic

open access: yesJournal of Medical Radiation Sciences, EarlyView.
Final‐year radiography students and experienced radiographers assessed 70 chest radiographs using structured criteria for positioning, sharpness and anatomical visibility. The level of agreement was good to excellent across all three domains, with an overall ICC of 0.90.
