Stair‐Climbing Wheelchairs for Enhanced Mobility: A Comprehensive Review of Fundamental Mechanisms, Design Concepts, and Performance Analysis

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT People with physical disabilities face significant mobility challenges while climbing uneven surfaces and staircases. In these circumstances, traditional wheelchairs do not provide stable, safely controlled mobility, underscoring the importance of building superior stair‐climbing wheelchairs for both medical and infrastructure purposes.

Dynamic Cell Division for Interference Management in Satellite Direct‐to‐Cell Systems

open access: yesInternational Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Direct‐to‐cell (D2C) connectivity enables future non‐terrestrial networks to provide service directly to standard terrestrial user equipment (UE) when terrestrial networks (TN) are unavailable. In this work, the satellite system is considered as a secondary network that supplements existing TN coverage while minimizing interference to the ...

Schools That Educate Students Who Transform Businesses and Change the World: The Transformative Role of Education for the Circular Economy

open access: yesSustainable Development, EarlyView.
ABSTRACT The linear economic model continues to intensify environmental degradation and resource depletion, yet education for the circular economy (ECE) remains underdeveloped, particularly within basic education and in the Global South. This study evaluates the feasibility and effectiveness of an ECE Programme grounded in active learning methodologies,

Symbols of Climate Action: Audit Labor and the Production of Carbon Credits

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT Voluntary carbon markets (VCMs) are promoted as tools for financing climate mitigation, yet their effectiveness and credibility remain contested. This article examines how carbon credits are produced and destabilized as symbols of climate action, emphasizing the forms of ecological and audit labor that sustain their legitimacy.

Vine Tendril‐Inspired Cold‐Programmable Shape‐Memory Polymer Composites Using Sugar Beet Pulp

open access: yesSmall, EarlyView.
Vine tendrils inspire a bio‐derived, cold‐programmable shape‐memory polymer composite (SMPC). Magnetically guided sugar beet pulp creates mesoscale heterogeneity within a glassy matrix, producing built‐in mechanical asymmetry for rapid, solvent‐free programming by simple stretching.
