VAE+DDPG: An Attention‐Enhanced Variational Autoencoder for Deep Reinforcement Learning‐Based Autonomous Navigation in Low‐Light Environments

Advanced Intelligent Systems, EarlyView.
Variational Autoencoder+Deep Deterministic Policy Gradient addresses low‐light failures of infrared depth sensing for indoor robot navigation. Stage 1 pretrains an attention‐enhanced Variational Autoencoder (Convolutional Block Attention Module+Feature Pyramid Network) to map dark depth frames to a well‐lit reconstruction, yielding a 128‐D latent code ...

Edge Information‐Augmented Auxiliary Diagnosis Method for Cervical Cancer in Medical Decision‐Making Systems

Advanced Intelligent Systems, EarlyView.
To address the problems of insufficient utilization of multiscale features and inefficient feature sharing between tasks in the model, this study proposes an edge‐enhanced intelligent cervical cancer screening method that achieves feature reuse and improves efficiency by jointly optimizing nucleolus segmentation and lesion classification.

Active Shell Engineering for Efficient Cascade Triplet Energy Transfer in Lanthanide Heterostructures

Angewandte Chemie, EarlyView.
Active shell engineering resolves the trade‐off between surface passivation and molecular sensitization in lanthanide nanoparticles. NaYbF4@Ca0.8F2:Nd0.2@ACA heterostructures transform inert shells into energy conduits, enabling cascade triplet transfer with near‐unity efficiency.

Device‐Level Implementation of Reservoir Computing With Memristors

Advanced Intelligent Systems, EarlyView.
Reservoir computing (RC) is an emerging computing scheme that employs a reservoir and a single readout layer, which can be actualized in the nanoscale with memristors. As a comprehensive overview, the principles of RC and the switching mechanisms of memristors are discussed, followed by actual demonstrations of memristor‐based RC and the remaining ...

Aminal‐linked Covalent Organic Frameworks for Light Energy Upconversion

Angewandte Chemie, EarlyView.
Aminal‐linked covalent organic frameworks incorporating anthracene units are introduced as solid‐state platforms for triplet–triplet annihilation upconversion. The crystalline materials retain chromophore electronic properties and exhibit fluorescence quantum yields of up to 40%.

Asymmetric Electrolytes Govern Tetrahydroxozincate Dynamics for Stable Alkaline Zinc Batteries

Angewandte Chemie, EarlyView.
This research tackles the limitations of alkaline zinc batteries by designing a series of metalloporphyrin molecules (Co‐4N, Co‐3N‐O, Co‐3N‐S) as electrolyte additives. The asymmetric structures, particularly Co‐3N‐O, accelerate the Zn(OH)42− decomposition via a modulated metal center and control Zn2+ transport through carboxyl groups.
