Advanced Science, EarlyView.Lipoic acid synthase (lias) can regulate α‐KG levels through lipoylation, thereby negatively regulating HIF‐1α protein levels via PHD under hypoixa. The Hap2 allele of lias exhibits lower expression levels than Hap1, leading to the accumulation of more HIF‐1α protein and thereby enhancing hypoxia tolerance. ABSTRACT Hypoxia stress seriously affects the

Cteno‐Bot: An Untethered Metachronally Swimming Robot With Magnetoactive Propulsors
Advanced Intelligent Systems, EarlyView.We present Cteno‐bot, an untethered ctenophore‐inspired robot which swims using metachronally coordinated appendages. A single mechanism controls up to 216 magnetoactive propulsors via a dynamically varying magnetic field. We show that the swimming speed of the robot can be increased without a corresponding increase in power requirement, simply by ...

Active Classification: Theory and Application to Underwater Inspection [PDF]
, 2016 We discuss the problem in which an autonomous vehicle must classify an object based on multiple views. We focus on the active classification setting, where the vehicle controls which views to select to best perform the classification. The problem is formulated as an extension to Bayesian active learning, and we show connections to recent theoretical ...

One‐Shot Multimaterial 3D Printing of a Flexible Spine for a Robotic Fish Prototype
Advanced Intelligent Systems, EarlyView.A one‐shot multimaterial 3D printing approach enables a monolithic soft robotic fish integrating a compliant spine and rigid vertebrae. Electromagnetic linear actuators drive tendon‐based transmission, producing controlled tail oscillations. Finite element modeling and experiments show strong agreement, while optimized material selection improves ...

Small‐Scale Magnetic Peristaltic Soft Robot With Mobility and Transport Capabilities
Advanced Intelligent Systems, EarlyView.This study introduces a miniature, untethered soft magnetic microrobot with peristaltic capabilities for both locomotion and cargo transport. Eight helically magnetized elastomeric strips deform under rotating fields (10–80 mT, 1–5 Hz), enabling movement across rods and lumina at up to 4.1 body lengths min‐¹.

American Journal of Industrial Medicine, EarlyView.ABSTRACT Background Work‐related injury and occupational disease remain major public health challenges worldwide; South Korea continues to report comparatively high industrial accident rates among OECD countries. To strengthen managerial accountability for worker safety, the Korean government enacted the Serious Accidents Punishment Act (SAPA) in 2021,
