Low-cost predictive models of dementia risk using machine learning and exposome predictors
Purpose: Diagnosing dementia, affecting over 55 million people globally, is challenging and costly, often leading to late-stage diagnoses. This study aims to develop early, accurate, and cost-effective dementia screening ...
Evaluation metrics in medical imaging AI: fundamentals, pitfalls, misapplications, and recommendations
Robust assessment of artificial intelligence (AI) models in medical imaging is paramount for reliable clinical integration. This international collaborative review paper provides an overview of key evaluation metrics across ...
From pathological to paradigmatic: A retrospective on Eremenko and Lyubich's entire functions
This paper surveys the impact of Eremenko and Lyubich’s paper “Examples of entire functions with pathological dynamics”, published in 1987 in the Journal of the London Mathematical Society. Through a clever extension and ...
La casa de los números pequeños
Un número algebraico es un número complejo que es raíz de un polinomio con coeficientes enteros. Estos números forman un cuerpo que se denota por $\overline{\mathbb{Q}}$, que es el lugar natural donde se encuentran soluciones ...
A review of evaluation approaches for explainable AI with applications in cardiology
Explainable artificial intelligence (XAI) elucidates the decision-making process of complex AI models and is important in building trust in model predictions. XAI explanations themselves require evaluation as to accuracy ...
Homemade algebraic geometry: celebrating Enrique Arrondo’s 60th birthday
In this survey we recognize Enrique Arrondo’s contributions over the whole of his career, recalling his professional history and collecting the results of his mathematical production.
An assessment of the European Patient Summary for clinical research: a case study in cardiology
Introduction: The European Health Data Space (EHDS) initiative was launched to create a unified framework for health data exchange across Europe. Central to this initiative is the European Electronic Health Record Exchange ...
New imaging signatures of cardiac alterations in ischaemic heart disease and cerebrovascular disease using CMR radiomics
Background: Ischaemic heart disease (IHD) and cerebrovascular disease are two closely inter-related clinical entities. Cardiovascular magnetic resonance (CMR) radiomics may capture subtle cardiac changes associated with ...
Cardiac magnetic resonance radiomics reveal differential impact of sex, age, and vascular risk factors on cardiac structure and myocardial tissue
Background: Cardiovascular magnetic resonance (CMR) radiomics analysis provides multiple quantifiers of ventricular shape and myocardial texture, which may be used for detailed cardiovascular phenotyping. Objectives: We ...
Girth in GF(q)-representable matroids.
We prove a conjecture of Geelen, Gerards, and Whittle that for any finite field GF $(q)$ and any integer $t$, every cosimple GF ( $q$ )-representable matroid with sufficiently large girth contains either $M\left(K_t\right)$ ...
Boundedness for proper conflict-free and odd colorings.
The proper conflict-free chromatic number, $\chi_{\mathrm{pcf}}(G)$, of a graph $G$ is the least positive integer $k$ such that $G$ has a proper $k$-coloring in which for each non-isolated vertex there is a color appearing ...
Higher rank prioritary bundles on ruled surfaces and their global sections
Let $X$ be a ruled surface over a nonsingular curve $C$ of genus $g \geq 0$. The main goal of this paper is to construct simple prioritary vector bundles of any rank $r$ on $X$ and to give effective bounds for the dimension ...
Vascular surgery study of the CGuard MicroNet-covered stent in patients with indication to carotid revascularization: POLGUARD
BACKGROUND: In a recent randomized study, MicroNet-covered stent (CGuard) significantly reduced procedural and post-procedural cerebral embolism in relation to a single-layer CREST study carotid stent, but real-life clinical ...
DeBasher: a flow-based programming bash extension for the implementation of complex and interactive workflows with stateful processes
Background: Bioinformatics data analysis faces significant challenges. As data analysis often takes the form of pipelines or workflows, workflow managers (WfMs) have become essential. Data flow programming constitutes the ...
Enhancing point cloud semantic segmentation via scalable domain adaptation with LoRA-enabled PointNet++
Semantic segmentation of airborne LiDAR point clouds enables a broad range of urban and environmental applications. However, domain shifts between training and operational data, as well asthefrequentemergenceofnewsemanti ...
Strict rearrangement inequalities: nonexpansivity and periodic Gagliardo semi-norms
This paper deals with the behavior of the periodic Gagliardo seminorm under two types of rearrangements, namely under a periodic, and respectively a cylindrical, symmetric decreasing rearrangement. Our two main results are ...
Inter-and Intraobserver Variability in Bowel Preparation Scoring for Colon Capsule Endoscopy: Impact of AI-Assisted Assessment Feasibility Study
This study assessed the reliability of AI-assisted bowel cleansing scoring in colon capsule endoscopy using the CC-CLEAR scale. While interobserver agreement was excellent with manual scoring among experienced readers, ...
Periodic solutions to integro-differential equations: variational formulation, symmetry, and regularity
We consider nonconstant periodic constrained minimizers of semilinear elliptic equations for integro-differential operators in $\mathbb{R}$. We prove that, after an appropriate translation, each of them is necessarily an ...
On the Arnold Diffusion Mechanism in Medium Earth Orbit
Space debris mitigation guidelines represent the most effective method to preserve the circumterrestrial environment. Among them, end-of-life disposal solutions play a key role. In this regard, effective strategies should ...
