Holistic foreground–background guided feature learning for few-shot strip steel defect segmentation

Strip steel surface defect (S 3 D) segmentation has become an indispensable technique for surface inspection in strip steel production lines. However, the imbalance between the foreground and background, as well as the complex defect appearances, have become the main challenges i...

Recent Advances in Radiative Cooling Architectural Coatings: From Optical Principles to Building Energy Savings

Radiative cooling architectural coatings reject solar gains while emitting terrestrial heat toward the cold sky, offering a passive route to reduce envelope heat gain and mechanical cooling demand. Its central argument is that high solar-weighted reflectance and long-wave emittan...

Conductive Binder Integrated with Hydrogen Bonding and Coulombic Interactions Enables Self-Healing and Robust Silicon Anodes

Abstract The poor conductivity and severe volume effect of silicon anodes lead to sluggish lithiation/delithiation kinetics and electrode pulverization, largely impeding the cyclability of the batteries. A multifunctional binder system that can simultaneously address these issues...

Photo‐Enhanced Electronic Metal–Support Interaction Boosts Low‐Temperature Water–Gas Shift Reaction via Ni δ+ –O V –Ce 3+ Interfacial Redox Cycling

ABSTRACT Nickel (Ni) is an attractive non‐noble‐metal catalyst for the water‐gas shift reaction (WGSR), yet strong CO adsorption and competing methanation severely limit its activity and selectivity. Herein, we develop a series of NiCe layered double hydroxide‐derived catalysts (...

Text Cannot Remove a Memory from Context: Update, Retraction, and Access Control in Language Models

Language models increasingly serve as long-term memory, and systems update or retract stored facts by writing text into the context. What do these writes actually change? Across model scales (0.5B–7B) and a second architecture family, we find that, for a system that controls the...

Real‐Time Observation of Soliton Buildup and Self‐Organization in a GHz Harmonic Mode Locked Fiber Laser

ABSTRACT Ultrafast fiber lasers operating at GHz repetition rates are critical for applications requiring high‐speed optical pulse sources. To achieve such rates, passive harmonic mode locking (HML) constitutes a logical pathway, whose practical implementation is hampered by the...

Fouling, Deactivation, and Self-Healing of Coordinatively Unsaturated Metal Sites in MOF-Derived Catalysts During Real Water Treatment

Coordinatively unsaturated metal sites (CUSs) are central to the adsorption, electron transfer, and oxidant-activation steps that make metal–organic-framework (MOF)-derived catalysts attractive for water purification. Their open coordination environment, however, also creates an...

Visitor-Centric Public Space Network Analysis: A Revised Node Efficiency Model for Spatial Intervention

Conventional spatial network analysis relies on topological metrics that neglect visitor behavioral dimensions, leading to systematic mismatches between structural centrality and actual spatial vitality. This study proposed a revised node efficiency model that incorporated three...

Charge functions for all dimensional partitions

The charge functions for n n -dimensional partitions are known for n=2,3,4 n = 2 , 3 , 4 in the literature. In a recent work, we gave the expression for arbitrary odd dimension; here we further conjecture a formula for all even-dimensional cases. This conjecture is proved rigorou...

Ultrastable Wide-Range Capacitive Pressure Sensors with CNTs-Pinned PDMS Foam Composite Dielectrics for Intelligent Tactile Perception

Abstract Flexible capacitive pressure sensors have attracted considerable attention for wearable electronics, intelligent robotics, and human-machine interfaces, yet achieving high sensitivity, broad pressure detection, and long-term stability remains challenging. Herein, carbon...

Weyl-Transition-Driven Giant Reversible Orbital Hall Conductivity

Abstract The orbital Hall conductivity (OHC) is central to orbitronics, yet its microscopic control remains largely unexplored. Here we identify a general mechanism in which tilted Weyl crossings formed by orbitally distinct bands generate a strongly asymmetric orbital Berry curv...

In Situ Bioorthogonal Synthesis of PROTACs via Dual‐Responsive Cleavage for Synergistic Photo‐Immunotherapy

ABSTRACT Limited aqueous dispersibility and potential off‐target toxicity hinder the development and clinical translation of proteolysis‐targeting chimeras (PROTACs). Herein, a bioactive self‐delivering “Split Nano‐Assembly of Photosensitizers and Targeting Chimeras” (SNAP‐TAC) t...

The Strong Electronic Metal–Support Interactions Mediated Direct Three‐Electron Oxygen Reduction for Enhanced Hydroxyl Radical Generation

ABSTRACT Hydroxyl radical (·OH) production in the traditional electro‐Fenton process relies on the two‐electron oxygen reduction reaction (2e − ORR) to generate H 2 O 2 , followed by activation by ferrous ions, suffering from low efficiency and mass‐transfer limitations. Herein,...

A Conduction‐Nucleation‐Competition‐Guided 3D Adaptive Gradient Buffer for Dendrite‐Free All‐Solid‐State Lithium Metal Batteries

ABSTRACT The existing designs of buffer for all‐solid‐state Li‐metal batteries (ASSLMBs) are mostly limited to static optimization of single functions and lack systematic regulation of the dynamic competition among ionic conduction, electron distribution, and interfacial lithioph...
