Unlocking Zenith Electronic State of Ni Sites in Ligand‐Engineered COFs for Efficient •O 2 − ‐Driven Uranium Photoreduction

ABSTRACT Photocatalytic uranium reduction via the superoxide radical (•O 2 − ) pathway is a sustainable route, but its efficiency is constrained by rapid charge recombination and poor O 2 activation. Herein, we develop a ligand engineering strategy to construct a series of Ni‐dik...

Spectral radius and Hamiltonicity in generalized split graphs

A graph G ˆ is a split graph if its vertex set can be partitioned into a clique S and an independent set I , and the cross edges join a vertex in S to a vertex in I . A generalized split graph G is obtained from the split graph G ˆ by replacing each vertex v of I with a clique S...

TCSF-Net: Transformer-Cloth Simulation Filtering Fusion Network for Semantic Segmentation of Densely Vegetated River Levee LiDAR Point Clouds

Accurate semantic segmentation of LiDAR point clouds from urban river levees is critical for flood hazard assessment and infrastructure maintenance, yet dense vegetation cover severely occludes the terrain and introduces ambiguous return signatures, challenging conventional filte...

Cross-view geo-localization through consistency-guided transformer and adversarial feature alignment

Cross-view geo-localization aims to determine the geographic position of a query image by matching it with a geo-referenced remote sensing image database. In UAV-to-satellite localization, this task is particularly important for navigation, monitoring, and spatial perception unde...
