How to reduce sampling error in species population monitoring: from theory to methods
Ecography, EarlyView.Progress towards national and international targets to halt and reverse declines in species' abundances will be assessed using multispecies indicators (MSIs). A distinction must be drawn between two MSIs. One is the ideal, but unobserved, MSI that would have been measured had all species and sites within the scope of the target been sampled.

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.A physics‐informed machine learning approach successfully decodes the complex catalytic activity of high‐entropy alloys for ammonia oxidation. By revealing a synergistic mechanism involving lattice and electronic couplings, the study identifies a superior “isolated‐surrounded” platinum motif.

International Journal for Numerical Methods in Fluids, EarlyView.Employing the moving least‐squares aided finite element method (MLS‐FEM) allows detailed thermal analysis in complex porous structures, such as polymeric foams, where the conductive heat transfer mechanism governs in the solid matrix and the convective mechanism dominates within the gas‐filled voids.

Advancing Mathematics at the Intersection of Operator Theory and Non-Associative Algebra
Journal of Operator and Non-Associative AlgebrasThis editorial introduces the inaugural issue of the Journal of Operator and Non-Associative Algebras (JONAA), a new platform dedicated to research at the intersection of operator methods and non-associative algebraic structures. It highlights the motivations for establishing the journal, emphasizing the growing need for a unified venue where ...

Operational Mathematics in Operator Algebras: A Complete Extension from Numbers to Operators
This work establishes a comprehensive theory of Operational Mathematics within the framework of operator algebras, including both commutative and noncommutative cases. The central idea is to extend the number of repetitions of basic mathematical operations (addition, multiplication, exponentiation, tetration, and higher-order hyperoperations) from ...

Immersed Boundary Projection Method for Boundaries With Slip Velocities
International Journal for Numerical Methods in Fluids, EarlyView.A formulation of the immersed boundary method for incompressible flow over arbitrarily‐shaped bodies with surface slip described by the Navier boundary condition is presented. The wall slip velocity and the boundary force are determined implicitly through a projection to satisfy both the boundary condition and the divergence‐free condition of the ...

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 ...

This monograph presents a complete, self-contained extension of Operational Mathematics– the theory of extending the repetition count of basic mathematical operations (addition,multiplication, exponentiation, tetration, and higher hyperoperations) from natural numbers to integers, rational numbers, real numbers, and complex numbers– to the setting of ...

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 ...

Meta-Operational Mathematics on Operator Algebras: From Commutative to Noncommutative Settings
This paper develops a systematic extension of Meta-Operational Mathematics to the realm of operator algebras, encompassing both commutative and noncommutative settings. We elevate operations on C*-algebras and von Neumann algebras to the status of independent mathematical objects, and study meta-operations---composition, involution, exponentiation ...
