Deterministic relation between optical polarization and lattice symmetry revealed in ion-doped single microcrystals
Peng Li, Yaxin Guo, Ao Liu +5
Rare-earth ions doped crystals are of great significance for micro-sensing and quantum information, whilst the ions in the crystals emit light with spontaneous partial polarization…
Predicting Daily Trading Volume via Various Hidden States
Shaojun Ma, Pengcheng Li
Predicting intraday trading volume plays an important role in trading alpha research. Existing methods such as rolling means(RM) and a two-states based Kalman Filtering method have…
GRAPHSPY: Fused Program Semantic-Level Embedding via Graph Neural Networks for Dead Store Detection
Yixin Guo, Pengcheng Li, Yingwei Luo +2
Production software oftentimes suffers from the issue of performance inefficiencies caused by inappropriate use of data structures, programming abstractions, and conservative compi…
Detector tilt considerations in high-energy Bragg coherent diffraction imaging: a simulation study
Siddharth Maddali, Marc Allain, Peng Li +2
This paper addresses three-dimensional signal distortion and image reconstruction issues in x-ray Bragg coherent diffraction imaging (BCDI) in the event of a general non-orthogonal…
Learning Forward Reuse Distance
Pengcheng Li, Yongbin Gu
Caching techniques are widely used in the era of cloud computing from applications, such as Web caches to infrastructures, Memcached and memory caches in computer architectures. Pr…
