Sound‐Based Assembly of Magnetically Actuated Soft Robots Toward Enhanced Release of Extracellular Vesicles

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Magnetic soft robots offer promise in biomedicine due to their wireless actuation and rapid response, but current fabrication methods are complex and have limited cellular compatibility. A new, contactless bioassembly strategy using hydrodynamic instabilities is introduced, enabling customizable, centimeter‐scale robots.

Dual Neural Network Framework with SPICE Integration for Fast and Accurate Transistor Modeling

open access: yesAdvanced Intelligent Systems, EarlyView.
Neural network (NN)‐based compact transistor models are often deployed and evaluated standalone due to the lack of compatibility with existing simulation program with integrated circuit emphasis (SPICE) software. Herein, the proposed dual‐NN framework with the best trade‐off between high speed and high accuracy is integrated into commercial SPICE ...

Secular Stagnation

open access: yes, 2014
This study analyzes the emergence of secular stagnation as the consequence of a rise in the preference for liquidity. Such a rise is caused by a persistent set of pessimistic expectations. This study also investigates the effectiveness of a broad range of demand-management policies in dealing with secular stagnation. To obtain these results, this study
