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

Journal 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.

ADAPT: An Autonomous Forklift for Construction Site Operation

Journal of Field Robotics, EarlyView.
ABSTRACT Efficient material logistics are critical in controlling costs and schedules in the construction industry. However, manual material handling remains prone to inefficiencies, delays, and safety risks. Autonomous forklifts offer a solution to streamline on‐site logistics, reducing reliance on human operators and mitigating labor shortages.

SMTC Configuration and Window Adjustment Strategies for Beam Hopping in NR‐NTN

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT Beam hopping is an effective transmission strategy for nonterrestrial networks (NTNs), enabling satellites to allocate limited power and spectrum resources across different geographical regions over time. However, in NR‐based NTN systems, beam hopping complicates synchronization monitoring because synchronization signal block (SSB) arrivals ...

What Do We Mean When We Say Epistemic Agency? How Considering Multiple Facets of Epistemic Cognition Can Clarify a Murky Theoretical Construct

Science Education, EarlyView.
ABSTRACT Opening space for students to help shape knowledge building practices in the classroom—that is, epistemic agency—is necessary to achieve a variety of goals held by the science education community. As such, many scholars have explored how students might be positioned with, perceive, and take up epistemic agency.

Hidden Costs of Ethical Fashion: Sustainable Development Goals and Garment Worker Exploitation in Bangladesh

Sustainable Development, EarlyView.
ABSTRACT Across garment factories in the Global South, the promise of “ethical fashion” coexists with poverty wages and retaliation. This study examines why the global call for decent work has not improved labor conditions in Bangladesh's ready‐made garment industry.
