A Non‐Parametric Framework for Correlation Functions on Product Metric Spaces

open access: yesInternational Statistical Review, EarlyView.
Summary We propose a non‐parametric framework for analysing data defined over products of metric spaces, a versatile class encountered in various fields. This framework accommodates non‐stationarity and seasonality and is applicable to both local and global domains, such as the Earth's surface, as well as domains evolving over linear time or time ...

Computation of General Inner-Outer and Spectral Factorizations [PDF]

open access: yes, 2000
In this paper, we solve two problems in linear systems theory: the computation of the inner-outer and spectral factorizations of a continuous-time system considered in the most general setting.

Green Bond Paper Topics, Journal Metrics and Post‐publication Diffusion

open access: yesJournal of Economic Surveys, EarlyView.
ABSTRACT Green bonds are important financial instruments in sustainable finance, generating a rapidly expanding academic literature. This paper identifies the topics analyzed in green bond academic research and examines how these topics are associated with journal and post‐publication diffusion metrics. Using 1048 paper abstracts published between 2015

Bayes linear covariance matrix adjustment [PDF]

open access: yes, 1995
In this thesis, a Bayes linear methodology for the adjustment of covariance matrices is presented and discussed. A geometric framework for quantifying uncertainties about covariance matrices is set up, and an inner-product for spaces of random matrices ...

Weak Exogeneity, Driving Trends and Non‐Causality. Is Dynamic Adjustment Informative About Causality?

open access: yesOxford Bulletin of Economics and Statistics, EarlyView.
ABSTRACT In VECMs (or CVARs), the weak exogeneity of some of the variables (for the long‐run parameters) is related to the equilibrium adjustment dynamics. This has sometimes led to the statistical concept of weak exogeneity being given a causal interpretation.

Superstatistical generalisations of Wishart-Laguerre ensembles of random matrices [PDF]

open access: yes, 2008
Using Beck and Cohen's superstatistics, we introduce in a systematic way a family of generalized Wishart–Laguerre ensembles of random matrices with Dyson index β = 1, 2 and 4. The entries of the data matrix are Gaussian random variables whose variances η

TAMAVAQ/Q‐TAMAVAQ: Fubini–study CTQW graph transport and constrained margin‐based ranking for neoantigen candidate prioritization in lower‐grade glioma and glioblastoma

open access: yesClinical and Translational Discovery, Volume 6, Issue 6, December 2026.
Abstract Background Personalized neoantigen vaccine design for glioma requires the integration of mutation‐derived peptide evidence, molecular properties, HLA coverage and finite manufacturing capacity. TAMAVAQ/Q‐TAMAVAQ combines quantum‐geometric descriptor representation with graph transport and auditable peptide‐panel assembly.

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

open access: yesThe International Journal of Health Planning and Management, Volume 41, Issue 6, Page 1159-1173, December 2026.
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 ...

Beyond General Creativity: The Role of STEM‐Specific Creative Activities in Shaping Career Interest

open access: yesThe Journal of Creative Behavior, Volume 60, Issue 4, December 2026.
ABSTRACT Despite growing consensus among educators and scholars that creativity is essential to student achievement in science, technology, engineering, and mathematics (STEM) fields, institutions of higher education rarely focus on developing key indicators of student creativity.

Data‐Driven Spectral Prediction for Accelerating Large‐Scale Electronic Structure Calculations

open access: yesProceedings in Applied Mathematics and Mechanics, Volume 26, Issue 4, December 2026.
ABSTRACT Simulating large molecular systems comprising thousands of atoms requires highly scalable methodologies. While modern Density Functional Theory (DFT) codes exhibit linear scaling, solving the associated large, sparse generalized eigenproblems remains a critical computational bottleneck on exascale architectures.
