Abstract 4D printing is widely used in soft actuators, flexible electronic devices, and robotics. However, existing printed architectures suffer from drawbacks such as long shape‐deformation response time or low sensitivity to external stimuli, which greatly limit their applications. To address these shortcomings, electromagnetic (EMAs) with both ultra‐fast highly‐sensitive detection capabilities have been proposed this study. The EMA composed of a polymeric scaffold, along magnetic...
The model-driven power allocation (PA) algorithms in the wireless cellular networks with interfering multiple-access channel (IMAC) have been investigated for decades. Nowadays, data-driven model-free machine learning-based approaches are rapidly developing this field, and among them deep reinforcement learning (DRL) is proved to be of great potential. Different from supervised learning, DRL takes advantages exploration exploitation maximize objective function under certain constraints. In...
Emerging memories have been developed as new physical infrastructures for hosting neural networks owing to their low-power analog computing characteristics. However, accurately and efficiently programming devices in an analog-valued array is still largely limited by the intrinsic non-idealities of devices, thus hampering applications in-situ training networks. Here, we demonstrate a passive electrochemical memory (ECRAM) with many important characteristics necessary accurate programming....

For low microwave band, the size of substrate integrated waveguide (SIW) couplers still need to be further reduced though other advantages profile, insertion loss, cost etc. are very remarkable. In this letter, novel folded (SIFW) narrow-wall single-slot and double-slot directional designed implemented. The measured results in good agreement with simulations. A corresponding SIW coupler is also for comparison. SIFW keeps almost all nearly a half reduction size.
