Electropermanent Magnetic Muscles: Power‐Efficient, Low‐Voltage, Compact Magnetic Actuators to Power Wearables and Untethered Robots

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents compact, low‐voltage actuators based on electropermanent magnetic interactions. The actuators show good overall performance across key metrics and are implemented in wearable devices and untethered robots. Their ability to operate in different configurations and hold positions without energy input highlights their potential for ...

Myoelectric Origami‐Based Soft Robotic Knee Exoskeleton to Enhance Sit‐to‐Stand Assistance in Elderly Populations

open access: yesAdvanced Intelligent Systems, EarlyView.
This work presents a lightweight Miura‐origami soft knee exoskeleton powered by vacuum actuation and integrated with a multimodal physiological intent‐recognition system, providing real‐time assistance during sit‐to‐stand movement to reduce muscle effort and improve user comfort.

Refining Detection of Subclinical Epileptiform Activity in Alzheimer's Disease: A Case–Control Study and Call for a Consensus

open access: yesAnnals of Neurology, EarlyView.
Objective Sleep‐predominant network hyperexcitability is increasingly recognized as a potential disease‐accelerating comorbidity in Alzheimer's disease (AD). However, its prevalence and risk‐factors remain debated, largely due to cohort‐specific and methodological differences across studies.

Uncovering Archaeological Treasures at Saruq al‐Hadid, UAE: Insights From Ground Penetrating Radar and Magnetic Data

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT Saruq al‐Hadid, located at the edge of the Rub Al‐Khali desert near Dubai's southern border with Abu Dhabi, is among the region's richest archaeological sites. Renowned for its historical role in metallurgy, trade and human habitation, the site was occupied from the Umm an‐Nar period through the post–Iron Age. Despite its significance, much of

Attitude transfer assembly design for MAGSAT [PDF]

open access: yes
A description is given of a design for an instrument system that will monitor the orientation of a boom-mounted vector magnetometer relative to the main spacecraft body. The attitude of the magnetometer is measured with respect to X and Z axes lateral to

Hiding in Plain Sight: Rethinking the Size and Complexity of Iron Age Hillforts in NW Iberia Thanks to Aerial Archaeology and Geophysics

open access: yesArchaeological Prospection, EarlyView.
ABSTRACT This paper tackles one key limitation in the analysis of Iron Age communities in the Northwestern Iberian Peninsula: the limited exploration of areas beyond the fortified settlements known as castros (hillforts). The vast majority of archaeological studies have focused exclusively on the areas inside the walls of these settlements, which are ...

A targeted antiferromagnetic nanoprobe for ultra‐sensitive magnetic resonance imaging detection of sub‐millimeter esophageal tumors

open access: yesBMEMat, EarlyView.
We developed a cyclo‐RGD peptide‐conjugated antiferromagnetic nanoparticle (RANP) as a targeted T1 contrast agent. Under 9 T MRI conditions, RANP exhibited an r1 value of 1.88 mM−1 s−1 and a low r2/r1 ratio of 1.84, enabling the detection of esophageal tumors as small as 0.8 mm in vivo. Abstract Early, non‐invasive detection of esophageal cancer at sub‐
