Dimension- and Facet-Dependent Altermagnetic Biferroics and Ferromagnetic Biferroics and Triferroics in CrSb
Long Zhang, Guoying Gao
Altermagnets have recently garnered significant interest due to their vanishing net magnetic moment and non-relativistic momentum-dependent spin splitting. However, altermagnetic (…
Asymmetric stress engineering of dense dislocations in brittle superconductors for strong vortex pinning
Meng Han, Chiheng Dong, Chao Yao +17
Large lossless currents in high-temperature superconductors (HTS) critically rely on dense defects with suitable size and dimensionality to pin vortices, with dislocations being pa…
Scavenger+: Revisiting Space-Time Tradeoffs in Key-Value Separated LSM-trees
Jianshun Zhang, Fang Wang, Jiaxin Ou +7
Key-Value Stores (KVS) based on log-structured merge-trees (LSM-trees) are widely used in storage systems but face significant challenges, such as high write amplification caused b…
Scavenger: Better Space-Time Trade-Offs for Key-Value Separated LSM-trees
Jianshun Zhang, Fang Wang, Sheng Qiu +6
Key-Value Stores (KVS) implemented with log-structured merge-tree (LSM-tree) have gained widespread acceptance in storage systems. Nonetheless, a significant challenge arises in th…
When Energy and Information Revolutions Meet 2D Janus
Long Zhang, Ziqi Ren, Li Sun +4
The depletion of energy sources, worsening environmental issues, and the quantum limitations of integrated circuits for information storage in the post-Moore era, are pressing glob…
STEPC: A Multi-energy Nonuniform Response Calibration Framework for Photon-Counting Micro-CT in Multi-material Imaging
Enze Zhou, Wenjian Li, Wenting Xu +6
Photon-counting computed tomography has demonstrated significant advancements in recent years; however, micro photon-counting CT (Micro-PCCT) systems are still limited by pixel-wis…
