Parton distribution functions and strong coupling constant: MSHT

T. Cridge · L.A. Harland-Lang · M. Reader · R.S. Thorne

We present an overview of the MSHT family of global PDF fits. We describe the underlying methodology, including parameterisation choice, theoretical inputs and datasets included in the fit. We describe the impact of recent theoretical advances in the inclusion of higher order QCD and EW corrections on the fit and their...

The quaternionic moment problem

Taher, R. Ben · Schmüdgen, K. · Zerouali, E. H.

In this paper we develop an approach to the full quaternionic moment problem. We define a hierarchy $ \mathbb{H}^{k}[q^{*}, q]\subset \mathbb{H}^{k+1}[q^{*}, q]$, $k\in \mathbb{N}_{0}\cup \{\infty \}$, of two-sided $\mathbb{H}$-linear spaces of quaternionic polynomials which are invariant under conjugation of quaternio...

On the algebraic properties of the Böröczky configurations

Jake Kettinger · Shahriyar Roshan Zamir

The Böröczky configuration of lines and (multiple) points exhibits extremal behavior in commutative algebra and combinatorics. Examples of this appear in the context of the containment problem for ordinary and symbolic powers and the proof of the Dirac-Motzkin conjecture by Green and Tao. This paper studies the algebra...

Self-eXplainable AI for medical image analysis: A survey and new outlooks

Junlin Hou · Sicen Liu · Yequan Bie · Hongmei Wang · y 3 más

The increasing demand for transparent and reliable models, particularly in high-stakes decision-making areas such as medical image analysis, has led to the emergence of eXplainable Artificial Intelligence (XAI). Post-hoc XAI techniques, which aim to explain black-box models after training, have raised concerns about th...

Parameter estimation in stochastic differential equations via Wiener chaos expansion and stochastic gradient descent

Francisco Delgado-Vences · Jose Julian Pavon-Español · Arelly Ornelas

This study addresses the inverse problem of parameter estimation for Stochastic Differential Equations (SDEs) by minimizing a regularized discrepancy functional via Stochastic Gradient Descent (SGD). To achieve computational efficiency, we leverage the Wiener Chaos Expansion (WCE), a spectral decomposition technique th...

Relaxed greedy randomized Kaczmarz with signal averaging for solving doubly-noisy linear systems

Lu Zhang · Jinchuan Zeng · Hui Zhang

Large-scale linear systems of the form $Ax=b$ are often doubly-noisy, in the sense that both its measurement matrix $A$ and measurement vector $b$ are noisy. In this paper, we extend the relaxed greedy randomized Kaczmarz (RGRK) method to the doubly-noisy systems to accelerate convergence. However, RGRK fails to conver...

QCD for electroweak precision measurements: Foundations

George Sterman

The couplings of the strong to electroweak sectors of the Standard Model enable the exploration of each using our growing knowledge of the other. In this review, we will follow the sweep of history. Starting with QED as a precision theory, deep inelastic scattering served as a gateway to the strong interactions, follow...

Eigenvalues and equivalence classes of third-order symmetric tensors

Lishan Fang · Hua-Lin Huang · Shengyuan Ruan · Yu Ye

This paper demonstrates that third-order real symmetric tensors cannot be classified up to equivalence by their eigenvalues only, thereby resolving a problem posed by Qi in 2006. By applying Harrison's center theory, we derive equivalence classes of $2 \times 2 \times 2$ symmetric tensors via the one-to-one corresponde...

Bivariate multiple orthogonal polynomials of mixed type on the step-line

Manuel Mañas · Miguel Rojas · Jianwen Wu

This article studies bivariate multiple orthogonal polynomials of the mixed type on the step-line. The analysis is based on the LU factorization of a moment matrix specifically adapted to this framework. The orthogonality and biorthogonality relations satisfied by these polynomials are identified, and their precise mul...

Japanese Encephalitis Vaccine Preferences and Uptake in Western Travelers and Locals: Strategies to Enhance Vaccine Uptake

Punyisa, Asawapaithulsert · Nabin, Poudel · Chayanis, Kositamongkol · Saranath, Lawpoolsri · y 4 más

Understanding the preferences aids in improving Japanese encephalitis (JE) vaccine uptake among populations at risk. This study aimed to determine the preferences, willingness to pay (WTP), and acceptance for JE vaccines of Western travelers and Thai locals.A discrete choice experiment was embedded in a survey of 300 W...
