Born this way: Does variation in perinatal limb bone morphology predict adult locomotor repertoire in primates?

open access: yesThe Anatomical Record, EarlyView.
Abstract Primates show a high degree of locomotor diversity that engenders similar variance in limb bone cross‐sectional geometry and bending strength: leaping primates have stronger hindlimb bones whereas suspensory species have stronger forelimb bones.

Forming limit curves for quasi-static and dynamic working-media-based forming processes [PDF]

open access: yes, 2018
The production of complex, multi-functional, high-strength components is becoming increasingly important in the sheet metal industry. Especially with small batch sizes, quasi-static working-media-based forming processes (WMF), such as hydromechanical ...

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

open access: yesThe 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.

From Prediction to Decision Making: PBPK and QSP as Regulatory‐Grade NAMs

open access: yesClinical Pharmacology &Therapeutics, EarlyView.
New approach methodologies (NAMs) encompass a diverse and rapidly evolving set of experimental and computational tools designed to generate human‐relevant mechanistic data for use in drug development and regulatory decision making. Experimental NAMs provide insights into drug disposition, pharmacological activity, and disease biology that are difficult

Optimal Lithium‐Ion Battery—Supercapacitor Energy Storage System Capacity for Off‐Grid Intermittent Renewable Energy Mini‐Grids

open access: yesEnergy Science &Engineering, EarlyView.
Deployment of an aging‐based controller during designing of optimal lithium‐ion battery—supercapacitor (LB‐Sc) hybrid energy storage system (HESS) capacity, in off‐grid IREMGs, improves performance of the LB and reduces its aging rate. Also, annualised cost of the LB‐Sc HESS improves by 33.15% in relation to optimal LB SESS.

Artificial neural network-based prediction of complete forming limit curves for steel in sheet metal forming

open access: yesJournal of Alloys and Metallurgical Systems
Forming Limit Curve (FLC) is crucial for predicting material formability and preventing defects in the sheet metal forming industry. Traditionally, FLCs are determined through Nakajima and Marciniak tests, which assess the material's response to various ...
