基于SfM-MVS的作物覆盖坡面微地形特征提取与分析

Shuitu Baochi Xuebao
目的为探究作物覆盖坡面地表微地形特征提取的可能性，实现作物覆盖条件下微地形三维建模与动态监测。方法采用SfM-MVS（structure from motion with multi-view stereo）方法，以玉米覆盖坡面为研究对象，裸坡作为对照，开展以裸坡及模拟微地形的标志物为基准，玉米覆盖条件下地表微地形构建提取和精度评估研究。结果1）玉米覆盖坡面控制点误差<0.002 m，稀疏点云与密集点云数量分别为裸坡的2.1、2.6倍。2）基于C2C（Cloud to Cloud）的结果表明 ...

Electrolyte–Framework Matching in High‐Voltage TEMPO‐COF Cathodes for Lithium Batteries

Advanced Science, EarlyView.
TEMPO‐functionalized covalent organic frameworks are investigated as high‐voltage cathodes for lithium batteries. Screening five electrolyte anions identifies lithium difluoro(oxalato)borate (LiDFOB) as the optimal electrolyte, balancing capacity, rate capability, and cycling stability, while buckypaper electrodes achieve high mass loading (40 mg cm−2)

Real‐Time Ferroelectric Domain Wall Dynamics During Electric Poling and Depoling

Advanced Science, EarlyView.
Real‐time visualization of domain wall dynamics during alternating‐current poling, direct‐current poling, and electrical depoling in relaxor‐PT ferroelectric single crystals reveals distinct field‐dependent pathways and strong path dependence. Instant polarized light microscopy uncovers reversible domain wall nucleation, motion, and reconfiguration ...

Cancer‐Associated BCL‐2 Mutants Reveal Mechanisms Towards Venetoclax Resistance

Advanced Science, EarlyView.
Venetoclax (VEN) resistance in chronic lymphocytic leukemia arises from diverse BCL2 mutations. We map mechanisms contributing to VEN resistance across common BCL‐2 variants. G101V and D103Y reduce drug binding and increase sequestration of pro‐apoptotic proteins. V156D blocks VEN allosterically.

MgP4/CNT‐Graphene Embedded in Hard Carbon Matrix as a High‐Capacity Anode for Next‐Generation Sodium‐Ion Batteries

Advanced Science, EarlyView.
Phosphorus‐rich MgP4 is introduced as a high capacity anode for sodium‐ion batteries (SIBs) via hybrid carbon matrix engineering. A sequential CNT/G assembly forms a conductive and mechanically robust network, delivering a high reversible capacity of 1386 mAh g−1 while stabilizing alloying reactions.
