Quantifying External Energy Inputs for Giant Planet Magnetospheres

open access: yesGeophysical Research Letters
The long‐standing “energy crisis” at the giant planets refers to the anomalous heating of planetary thermospheres compared to the available energy from solar irradiance. The coupling between planetary magnetospheres and their upper atmospheres is thought

The Impact of a Visualized Steerable Sheath on Radiofrequency Catheter Ablation for First‐Time Atrial Fibrillation Ablation: A Prospective, Randomized, Single‐Blind Study

open access: yesCatheterization and Cardiovascular Interventions, EarlyView.
ABSTRACT Background A 3D electroanatomical mapping (3D‐EAM) visualized steerable sheath was designed to improve catheter placement and reduce radiation exposure during ablation, an established treatment for atrial fibrillation (AF). However, prospective randomized data comparing the procedural and clinical outcomes of visualized and non‐visualized ...

An Ultra‐Low‐Power Biopotential Acquisition Analog Front‐End Chip for Wearable Devices

open access: yesInternational Journal of Circuit Theory and Applications, EarlyView.
A 0.8‐V, 1.2‐μW biopotential AFE combines a chopper‐stabilized CCIA with dual‐time‐scale EDO management. The slow DSL preserves > 1 GΩ input impedance, whereas an event‐triggered fast‐recovery path shortens return to the linear range after abrupt electrode‐offset disturbances. ABSTRACT A 0.8‐V, 1.2‐μW biopotential analog front‐end (AFE) IC is presented

Programmable crack dynamics engineering enables flexible strain sensors with high linearity

open access: yesFlexMat, EarlyView.
First‐decoupling theoretical framework of crack evolution elucidating the control methods, mechanistic insights, and structure‐activity relationships is established. Crack propagation from uncontrollable randomness systematically evolves into spatially ordered states.

Recent advances in multifunctional soft robots: A materials–structures–systems co‐design perspective for synergistic integration

open access: yesFlexMat, EarlyView.
Abstract Soft robots, engineered from highly compliant materials, offer superior adaptability and safety in unstructured environments compared to their rigid counterparts. Recent advancements, fueled by bio‐inspiration and material programmability, have led to the rapid co‐evolution of their core modules: actuation, sensing, protection, energy, and ...

Multi‐synergistic strategy for dual‐sensing conductive hydrogels capable of simultaneous strain and temperature monitoring

open access: yesFlexMat, EarlyView.
In this study, a multicomponent synergistic strategy is utilized, which capitalizes on the “intersection” of multiple functional influencing factors to achieve the successful development of a multifunctional hydrogel. Through the construction of a unique three‐dimensional dynamic cross‐linked network, the material combines mechanical strength ...

Spiritual Cannibalism in HRD: How Workplace Spirituality Devours Sacred Traditions

open access: yesHuman Resource Development Quarterly, EarlyView.
ABSTRACT This paper interrogates how the discourse of workplace spirituality in human resource development (HRD) operates as a tool of colonization. Through a systematic review of 48 articles published between 1997 and March 2025, the study uncovers recurring patterns of spiritual appropriation in which non‐Western traditions are detached from their ...
