With the rapid development of artificial intelligence and robotic engineering, traditional pre-programmed robot control systems can no longer adapt to complex, dynamic, and unstructured working environments. Robot autonomous learning has be...
Industrial mergers and acquisitions often involve complex ownership changes, debt restructuring, cross-border suppliers, asset transfers, related-party transactions, and post-merger integration pressure. Financing risk may rise after a tran...
Pulmonary vessel segmentation is often evaluated as a binary labeling problem, yet the anatomy to be recovered is a sparse, branching, multiscale network. A small break in a distal artery can have little influence on regional overlap while...
Data-platform agents operate in environments where schemas, APIs, organizational policies, and local practices change continuously. Static prompts and fixed tool descriptions therefore decay, while unconstrained learning from successful int...
Language-model assistants are frequently evaluated at the moment they generate SQL or transformation code, although production data engineering succeeds or fails across a much longer artifact lifecycle. Requirements are interpreted, sources...
The active sites of mixed-oxide catalysts often form dynamically under reaction conditions, making their identification difficult by ex situ characterization alone. Herein, first-principles thermodynamics and density functional theory were...

Low-temperature CO oxidation over inverse oxide–perovskite catalysts is governed by the mobility of active oxygen species at the interface. In this work, inverse CuOx/perovskite catalysts were prepared by depositing dispersed CuOx domains o...
Cu–ZrOx catalysts have attracted increasing attention for CO2 hydrogenation to methanol because the oxide–metal perimeter can simultaneously activate CO2-derived intermediates and dissociate hydrogen. In this work, density functional theory...

Understanding the dynamic nature of active sites is essential for improving Cu-based catalysts in CO2 hydrogenation to methanol. In this study, Cu–oxide catalysts were examined by operando X-ray absorption spectroscopy, in situ DRIFTS, H2-T...
