An Active Knee–Ankle–Foot Orthosis With Torque‐Dense, Low‐Impedance Knee Actuation

open access: yesAdvanced Intelligent Systems, EarlyView.
This article presents the simulation, design, and clinical validation of a robotic active KAFO with torque‐sensitive actuation. By passively and continuously adapting the transmission ratio in response to the knee torque, the torque‐sensitive actuator overcomes the tradeoff between torque, weight, and impedance observed in conventional robot actuators,

Australian Activists as Storytellers in Digital Spaces: Acquiring Skills, Producing Content and Getting the Message Out

open access: yesAustralian Journal of Social Issues, EarlyView.
ABSTRACT As modes of activism rapidly evolve, activists—both seasoned and emerging—must increasingly navigate a hybrid terrain of both digital and non‐digital engagement. This paper draws on the personal narratives of 16 nascent activists based in Australia to explore how they develop competencies related to digital storytelling, which is critical to ...

Animal stroke models and outcome evaluation: A review

open access: yesAnimal Models and Experimental Medicine, EarlyView.
Rodents are the preeminent stroke model species. Large animal models exist too, but are poorly standardized. Ischemic and hemorrhagic experimental models are available, with the intraluminal filament model being predominant. Outcomes are evaluated via quantifying subjects' sensorimotor impairment, cognitive memory faculties, degree of cellular ...

On the Impact of Mechanical Constraint on Band Structure and Photo‐Elastic Effect in Photonic Resonators

open access: yesAdvanced Physics Research, EarlyView.
We computationally investigate the mechanical, electronic, and optical properties of strained GeSn microdisks on silicon substrates. By combining photo‐elasticity, strain‐dependent band‐structure calculations, and optical mode analysis, we study how strain distribution, structural configuration, and temperature affect the electronic band structure and ...

Computational fluid dynamics simulations of airflow through the nasal passages of rhinolophoid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The nasal passages of bats that emit their echolocation call through their nostrils have adapted for sound emission as well as standard respiratory and olfactory functions. Rhinolophids, hipposiderids and rhinonycterids all use a high duty cycle (HDC) echolocation strategy.

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...
