Fractional order generalized Richards growth model with delay arguments on coupled networks [PDF]

Computational Ecology and Software
This study aims to examine the dynamical behavior of Caputo fractional order generalized Richards growth model with delay. In order to transition from continuous time model to a discrete version, piecewise constant arguments are added to the model and ...

Harnessing machine learning and optimization for informed chemical engineering decisions: A styrene reactor analysis

The Canadian Journal of Chemical Engineering, EarlyView.
This study shows that integrating multiple machine learning models with optimization and decision‐making improves chemical process design, and that a consensus‐based strategy across models provides more robust and reliable operating recommendations than any single model, especially under limited or noisy data conditions.

Copula‐based joint modelling of emergency department visits with time‐varying dependence

Canadian Journal of Statistics, EarlyView.
Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

Vine copula knockoffs for variable selection in gene expression studies

Canadian Journal of Statistics, EarlyView.
Abstract Identifying clinical and genetic markers is essential for stratifying cancer patients by survival outcomes and guiding personalized treatment strategies. However, gene expression studies often involve high‐dimensional predictors with mixed data types and complex dependence, which complicates reliable variable selection.

Do Firms Disclose Financially Material ESG Risks? Evidence From Japanese Food and Beverage Firms Using a Text Match Pretrained Transformer

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT This study develops a financial materiality‐oriented measure of ESG disclosure and examines how sustainability disclosures respond to evolving regulatory frameworks. Focusing on listed food and beverage firms in Japan from 2020 to 2024, we apply the Text Match Pretrained Transformer (TMPT) to assess the semantic relevance between disclosures ...

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Feeling Better Before, Not After: An Ecological Momentary Assessment of Affect Around Exercise in Women With Eating Disorders

International Journal of Eating Disorders, EarlyView.
ABSTRACT Objective Maladaptive exercise includes excessive, compulsive, or compensatory exercise and is a common eating‐disorder (ED) symptom associated with increased severity, slower rates‐of‐recovery, and faster rates‐of‐relapse. Affect‐regulation theories posit that maladaptive exercise functions to reduce high negative affect (NA), although ...
