Synthetic aperture radar image segmentation with quantum annealing

IET Radar, Sonar & Navigation
In image processing, image segmentation is the process of partitioning a digital image into multiple image segments. Among state‐of‐the‐art methods, Markov random fields can be used to model dependencies between pixels and achieve a segmentation by ...

Utilising Benford's Law in the Validation of Precipitation Datasets

International Journal of Climatology, EarlyView.
This study demonstrates Benford's Law as a robust diagnostic tool for precipitation data integrity. Global monthly precipitation consistently conforms to the law, regardless of origin, while regional data requires appropriate temporal granularity for adherence.

A Novel Map Matching Method Based on Improved Hidden Markov and Conditional Random Fields Model

International Journal of Digital Earth
Aiming at the inherent “labeling bias” problem of Hidden Markov Models (HMMs) in the process of low-frequency sampling rate GPS trajectory map matching, this paper proposes a map matching method that combines HMMs and Conditional Random Field Models ...

Elevated quinolizidine alkaloid content in grains of sweet narrow‐leaved lupins when intercropped with oats

Journal of the Science of Food and Agriculture, EarlyView.
Abstract BACKGROUND Narrow‐leaved lupins (NLL, Lupinus angustifolius L.) is recognized as a climate‐resilient protein crop but its use in food and feed is frequently limited by toxic quinolizidine alkaloids (QAs). The effect of intercropping with spring oat (Avena sativa L.) on grain QA content has not yet been quantified.

Desertification Risk: Bibliometric Analysis and Future Research Directions

Land Degradation &Development, EarlyView.
ABSTRACT Desertification, driven by climatic and anthropogenic factors, is one of the most pressing global environmental challenges, causing significant economic, ecological, and social consequences. A bibliometric analysis was performed to identify research trends and gaps in the desertification risk topic.

Extending the hyper‐logistic model to the random setting: New theoretical results with real‐world applications

Mathematical Methods in the Applied Sciences, EarlyView.
We develop a full randomization of the classical hyper‐logistic growth model by obtaining closed‐form expressions for relevant quantities of interest, such as the first probability density function of its solution, the time until a given fixed population is reached, and the population at the inflection point.

High-risk human papillomavirus cervical infection prevalence: a nationwide retrospective study comparing opportunistic and organised screening, France, 2020 to 2023

Eurosurveillance
BACKGROUND In France, cervical cancer screening for females aged 30­–65 years primarily tests for high-risk (HR) human papillomavirus (HPV) infections. AIM We aimed to map the prevalence of cervical infections caused by HPV16 and/or 18, or by any of 12 ...

On the Mean‐Field Limit of Consensus‐Based Methods

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Consensus‐based optimization (CBO) employs a swarm of particles evolving as a system of stochastic differential equations (SDEs). Recently, it has been adapted to yield a derivative free sampling method referred to as consensus‐based sampling (CBS). In this paper, we investigate the “mean‐field limit” of a class of consensus methods, including
