A pattern‐oriented simulation for forecasting species spread through time and space: a case study on an ecosystem engineer on the move

Ecography, EarlyView.
Modelling the spread of introduced ecosystem engineers is a conservation priority due to their potential to cause irreversible ecosystem‐level changes. While existing models predict potential distributions and spread capacities, new approaches that simulate the trajectory of a species' spread over time are needed.

Associations Between Socioeconomic, Spatial and Educational Factors and Midlife Periodontal Disease Risk: Evidence From ‘High School and Beyond’

Journal of Clinical Periodontology, EarlyView.
ABSTRACT Background Periodontal disease (PD) is a prevalent, preventable and treatable oral infection associated with substantial morbidity globally. There is little information from population‐representative cohort studies about the sociodemographic, educational and other early life factors that stratify PD risk.

A Mixture Transition Distribution Modeling for Higher‐Order Circular Markov Processes

Journal of Time Series Analysis, EarlyView.
ABSTRACT This study considers the stationary higher‐order Markov process for circular data by employing the mixture transition distribution modeling. The underlying circular transition distribution is based on Wehrly and Johnson's bivariate joint circular models.

Automatic tiny crack positioning and width measurement with parallel laser line‐camera system

Computer-Aided Civil and Infrastructure Engineering, EarlyView.
Abstract Quantifying tiny cracks is crucial for assessing structural conditions. Traditional non‐contact measurement technologies often struggle to accurately measure tiny crack widths, especially in hard‐to‐access areas. To address these challenges, this study introduces an image‐based, handheld parallel laser line‐camera (PLLC) system designed for ...
