Integrable sigma models with Haantjes structure on the H4 Lie group

Nuclear Physics B
By solving algebraic relations for the conditions of Haantjes structure on a Lie algebra G and by using the corresponding automorphism group we proceed to classify all inequivalent algebraic Haantjes structures on G.

A Multi‐Objective Periodic Vehicle Routing Model for Sustainable Healthcare Waste Collection

The International Journal of Health Planning and Management, EarlyView.
ABSTRACT The collection of infectious waste from healthcare facilities (HCF) constitutes a recurring operational challenge. Indeed, despite the inherent health risks posed by the storage and the transportation of infectious materials, most of the existing waste collection systems tends to prioritise cost optimization and to underaddress the safety ...

Economies of Scale to Consumption in Collective Households

Journal of Applied Econometrics, EarlyView.
ABSTRACT Browning et al. (2013) model collective‐household economies of scale in goods consumption by having each good be partly shared, instead of each good being public or private. We modify their model to achieve simple point identification and estimation of the economies of scale of consumption of each good, and we provide a new index of household ...

The Metric Dimension of Algebraic Constructed Graph of Dihedral Group Dn

Scientific Annals of Computer Science
In this article, we discusses the concept of metric dimension in graph theory and its applications in various scientific fields. Metric dimension is the minimum number of vertices in a graph that can uniquely identify all other vertices based on their ...

Catalan Bounds for Symmetric Strength‐Two Orthogonal Arrays

Journal 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 ...

Magnetic resonance imaging‐based axial‐plane analysis of lower extremity torsion with dedicated 3D planning software is reliable and efficient

Knee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose The reliability and efficiency of a dedicated 3D planning software were evaluated for magnetic resonance imaging (MRI)‐based measurement of femoral torsion, tibial torsion, knee version and whole‐lower extremity torsion compared with manual assessment.
