The 2‐D Orthogonal Packing Problem With Multiple Levels of Prioritization: A Spatial Optimization Perspective

open access: yesNaval Research Logistics (NRL), Volume 73, Issue 8, Page 1279-1300, December 2026.
ABSTRACT This paper addresses two‐dimensional orthogonal packing within a confined space, integrating bin packing principles with facility layout concepts to address scenarios in which items must not only fit but also be arranged according to spatial priorities.

Per‐Channel Complex B1+$$ {B}_1^{+} $$ Mapping for Parallel Transmit Ultra‐High Field MRI

open access: yesNMR in Biomedicine, Volume 39, Issue 12, December 2026.
Transmit‐field inhomogeneities beset ultra‐high field (UHF) MRI scans using single‐channel transmission or circularly polarised (CP) mode. Parallel transmission mitigates these artefacts but requires accurate subject‐specific per‐channel complex (magnitude and phase) B1+$$ {B}_1^{+} $$ maps. We explain the theory of per‐channel complex B1+$$ {B}_1^{+} $

On the Complexity of the Paper Selection Problem for the Italian Research Quality Evaluation (VQR)

open access: yesNetworks, Volume 88, Issue 4, Page 437-452, December 2026.
ABSTRACT This work addresses the paper selection problem that each Italian university and department faced in the context of the research quality evaluation (VQR) of the Italian university system for the period 2020–2024. Given the set of researchers of a university and their associated papers, the problem consists of selecting a fixed number of ...

Statistical Monitoring of Multivariate Count Data From Real‐Time Particle Counters

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 8, Page 4765-4809, December 2026.
ABSTRACT In the pharmaceutical industry, production environments are monitored for bacterial contamination. Particle counters are increasingly investigated for real‐time monitoring of viable microorganisms using count data for different particle size intervals.

A Case Study to Monitor Parallel‐Connected Ni–Cd Batteries on EMU Trains Through Compositional Data Control Charts

open access: yesQuality and Reliability Engineering International, Volume 42, Issue 8, Page 5311-5326, December 2026.
ABSTRACT Electric multiple unit (EMU) trains, widely used in modern railway transportation, use Nickel–Cadmium (Ni–Cd) batteries to power auxiliary systems on board, including lighting, ventilation, control electronics, and emergency systems. These batteries are often connected in parallel to ensure a wider power supply range for electrical loads that ...

Spectroscopic Analysis of Hydration Structures in PEG‐ and PMPC‐Containing Hydrogels by Pressure‐Controlled ATR‐IR Combined With Multivariate Curve Resolution

open access: yesSurface and Interface Analysis, Volume 58, Issue 12, Page 1071-1080, December 2026.
ABSTRACT Hydration structures govern the properties and functions of hydrogels, yet selectively measuring hydration water in the presence of abundant bulk water remains analytically challenging. Here we applied pressure‐controlled attenuated total reflection infrared spectroscopy (ATR‐IR) combined with multivariate curve resolution (MCR) analysis, a ...

On the additive image of zeroth persistent homology

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract For a category X$X$ and a finite field F$F$, we study the additive image of the functor H0(−;F)∗:rep(X,Top)→rep(X,VectF)$\operatorname{H}_0(-;F)_* \colon \operatorname{rep}(X, \mathbf {Top}) \rightarrow \operatorname{rep}(X, \mathbf {Vect}_F)$, or equivalently, of the free functor rep(X,Set)→rep(X,VectF)$\operatorname{rep}(X, \mathbf {Set ...

Long‐time asymptotics of a full soliton gas for the Camassa–Holm equation

open access: yesTransactions of the London Mathematical Society, Volume 13, Issue 1, December 2026.
Abstract We investigate the long‐time asymptotics of a full soliton gas for the Camassa–Holm equation. The analysis starts from a pure‐soliton Riemann–Hilbert (RH) problem with 2N$2N$ poles and two distinct types of residue conditions. We prove that, as N→∞$N\rightarrow \infty$, this discrete RH problem converges to a limiting soliton gas RH problem ...
