High‐Brightness and Ultra‐Long‐Lifetime Spin Quantum Dot Light‐Emitting Diodes Enabled by Efficient Injection of Spin‐Polarized Holes Through a Hybrid Hole Transport Layer

Advanced Science, EarlyView.
This work employs a hybrid hole transport layer to enhance hole transport efficiency, resulting in improved performance for the final device. It achieves an external quantum efficiency of 6.68%, a circularly polarized electroluminescence asymmetry factor of 0.026, and a high luminance of 14,370 cd/cm2, representing the highest luminance reported to ...

A Spatiotemporal Single‐Cell Atlas Uncovers Dysregulated ECM Dynamics and Septal Remodeling Arrest in Human Ventricular Septal Defects

Advanced Science, EarlyView.
Integrating single‐cell and spatial transcriptomics reveals human ventricular septal defect (VSD) as a disease of microenvironmental insufficiency and structural remodeling arrest. Attenuated endothelial‐fibroblast crosstalk, alongside downregulated THBS1/TGF‐β1 and MMP2 signaling networks, impairs the endothelial‐to‐mesenchymal transition (EndoMT) and

Real‐Time Multicolor Fluorescence Microscopy via Cross‐Channel Acquisition and Deep‐Learning‐Based Inference

Advanced Intelligent Discovery, EarlyView.
Sequential multicolor fluorescence imaging in dynamic microsystems is constrained by acquisition speed and excitation dose. This study introduces a real‐time framework to reconstruct spectrally separated channels from reduced cross‐channel acquisitions (frames containing mixed spectral contributions).

From Swarm to Individual: Emergent Individuality in Light‐Mediated Robot Collectives

Advanced Intelligent Systems, EarlyView.
Can individuality emerge from a swarm? Using nominally homogeneous phototactic robots, we show that collective light conditions reorganize robot‐level behavioral profiles. Global illumination amplifies persistent differences in state occupancy, while robot‐mounted local light cues reduce fixed differentiation and favor transient high‐switching profiles.

1,4‐Brook Rearrangement of β‐Silyl Allylic Alcohols: Trisubstituted Alkenes by Copper‐Mediated Stereoretentive ipso‐Substitution Reactions

Angewandte Chemie, EarlyView.
To fully leverage the power of the ruthenium‐catalyzed trans‐hydrosilylation of propargyl alcohols, it was necessary to develop a practical and robust method for the activation of those products that carry the silyl group distal to the hydroxy substituent.

Toward Complex In‐Car Environment Human–Vehicle Interactions Through Smart Glasses and sEMG‐Based Gesture Recognition

Advanced Intelligent Systems, EarlyView.
This study proposes a novel weighted random forest multimodal fusion method that combines smart glasses and sEMG data for in‐vehicle gesture interaction. It realizes stable performance in dim, occluded, and other constrained scenarios, providing feasible solutions and laying a foundation for universal human–machine interaction.

A Generalizable Framework for Building Executable Domain‐Specific Large Language Models Under Data Scarcity: Demonstration on Semiconductor Technology Computer‐Aided Design Simulation

Advanced Intelligent Systems, EarlyView.
A schema‐first alignment framework builds compact, executable domain‐specific language models under data scarcity. Large‐scale synthetic question‐answer generation instills domain knowledge, and a code‐centric IR‐to‐DPO pipeline aligns generation with tool‐executable syntax.
