A Densely Connected End-to-End Neural Network for Multiscale and Multiscene SAR Ship Detection

IEEE Access, 2018
Synthetic aperture radar (SAR) images have been widely used for ship monitoring. The traditional methods of SAR ship detection are difficult to detect small scale ships and avoid the interference of inshore complex background.

Astrocytic FDX1 Contributes to Copper Dyshomeostasis‐associated Synaptic Dysfunction in Depression and Is Modulated by Exercise

Advanced Science, EarlyView.
Chronic stress disrupts copper homeostasis and promotes copper accumulation in the prelimbic cortex, leading to astrocytic FDX1 upregulation. Elevated astrocytic FDX1 impairs calcium signaling, induces structural atrophy, and disrupts synaptic function, contributing to depressive‐like behaviors. Physical exercise reverses these alterations by restoring

Molecularly Engineered Wing‐Shaped Azobenzene Memristors for Logic‐in‐Memory and Edge Visual Intelligence

Advanced Science, EarlyView.
Rational engineering of terminal substituents in symmetric azobenzene‐based molecules enables precise control over conformationally coupled charge‐transfer processes. This design yields tunable nonvolatile resistive memory behaviors, ranging from write‐once‐read‐many‐times (WORM) to rewritable switching.

Microprotein MP104 Promotes Malignant Progression of Colorectal Cancer Through Regulating Protein Translation

Advanced Science, EarlyView.
A previously unrecognized microprotein, MP104, encoded by ZEB1‐AS1, emerges as a critical driver of colorectal cancer progression. MP104 links ubiquitin‐mediated protein degradation with translational reprogramming via the UBE2O–AMPKα2–mTOR–EIF4B axis, revealing an unrecognized layer of oncogenic regulation.
