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

open access: yesMathematical 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.

Uncertainty, Sensitivity, and Efficiency Analysis of a Hybrid Piezoelectric–Electromagnetic Energy Harvester

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Digitalization and emerging technologies are increasing the demand for wireless sensing and the Internet of Things (IoT), which provide opportunities for autonomous sources of electricity in the form of energy harvesting systems. This paper focuses on the challenges in hybrid piezoelectric‐electromagnetic kinetic energy harvesting systems that

An Adaptive Multiple Shooting Strategy for Optimal Control

open access: yesOptimal Control Applications and Methods, EarlyView.
We study how multiple shooting affects the convergence of Newton‐type methods for optimal control, comparing several shooting strategies across 40 benchmark problems. The study covers interior‐point and sequential quadratic programming methods with both Quasi‐Newton approximations and exact Hessians.

Digital fire technologies and community networks: Cultivating just sociotechnical practices for living with planetary change

open access: yesPeople and Nature, EarlyView.
Abstract Fires are expanding in frequency and intensity worldwide due to climate change and land‐use transformations. At the same time, fire often plays a regenerative role in ecosystems. Traditional and cultural practices incorporate fire use for landscape management and landscape renewal. In this complex matrix of fire ecologies, digital technologies

Practical considerations for pathologists when selecting digital pathology systems: an ESDIP guide

open access: yesThe Journal of Pathology, EarlyView.
Abstract The implementation of digital pathology (DP) has been reported across academic, public, and private laboratory settings, providing valuable insights into workflow transformation. However, comparatively little guidance exists on how DP systems should be evaluated prior to acquisition and deployment.

Transforming Coastal Waste: Algae‐Based Recycled HDPE Composites for Enhanced Sustainability

open access: yesPolymer Engineering &Science, EarlyView.
Manufacturing and characterization of composites from beach‐cast algae waste combined with recycled high‐density polyethylene. ABSTRACT Growing environmental concerns are accelerating the development of more sustainable materials. This study successfully created a composite material by combining recycled high‐density polyethylene (HDPE) as the matrix ...
