DuckyDog: An Erect Amphibious Robot with Variable‐Stiffness Legs and Passive Fins
Advanced Intelligent Systems, EarlyView.DuckyDog, a quadruped amphibious robot using erect posture, is proposed with dog‐inspired tendon‐driven compliant legs for walking and paddling, a duck‐inspired body for buoyancy, and passive fins to increase propulsion. It achieves maximum speeds of 0.4 body lengths per second on land and 0.3 on water, demonstrating the ability to navigate in complex ...

Toward Natural Limb Function: A New Era in Prosthetic Innovation
Annals of Neurology, EarlyView.The past decade has witnessed groundbreaking clinical implementation of neuroprosthetic limbs driven by signals from peripheral targets (eg, nerves and muscle) and the brain to restore limb function for individuals with limb loss or impairment. In this review, we highlight recent key clinical trials in peripheral neuroprosthetic interfaces directly ...

Axion‐Like Interactions and CFT in Topological Matter, Anomaly Sum Rules and the Faraday Effect
Advanced Physics Research, EarlyView.This review investigates the connection between chiral anomalies and their manifestation in topological materials, using both perturbative methods based on ordinary quantum field theory and conformal field theory (CFT). It emphasizes the role of CFT in momentum space for parity‐odd correlation functions, and their reconstruction by the inclusion of a ...

Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
The Anatomical Record, EarlyView.Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),
