Kavli Affiliate: Kejia Lee | First 5 Authors: , , , , | Summary: In this study, we report multi-year polarization measurements of four repeating FRBs initially discovered by CHIME: FRBs~20190117A, 20190208A, 20190303A, and 20190417A. We observed the four repeating FRBs with FAST, detecting a total of 66 bursts. Two bursts from FRB~20190417A exhibit a […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Chen Zhang, Chen Zhang, , , | Summary: Some recent pulsar observations cannot naturally fit into the conventional picture of neutron stars: the compact objects associated with HESS J1731-347 and XTE J1814-338 have too small radii at the low-mass regime, while the secondary component of GW190814 is […]
Kavli Affiliate: Renxin Xu | First 5 Authors: Zhaosheng Li, Zhaosheng Li, , , | Summary: SRGA J144459.2$-$604207 is a newly confirmed accreting millisecond X-ray pulsar and type I X-ray burster. We present the broadband X-ray timing and spectral behaviors of SRGA J144459.2$-$604207 during its 2024 outburst. The data were collected from NICER, Einstein Probe, […]
Kavli Affiliate: Ran Wang | First 5 Authors: Fei Yuhuan, Fei Yuhuan, , , | Summary: Early detection and diagnosis of diabetic retinopathy is one of the current research focuses in ophthalmology. However, due to the subtle features of micro-lesions and their susceptibility to background interference, ex-isting detection methods still face many challenges in terms […]
Kavli Affiliate: Kejia Lee | First 5 Authors: Zhengli Wang, Zhengli Wang, , , | Summary: In this work, we observe the nearby pulsar, PSR B1929$+$10, using the Five-hundred-meter Aperture Spherical radio Telescope (FAST). We find, for the first time, two new emission components with an extremely weak observed flux density of about $10^-4$ of […]
Kavli Affiliate: Luis Ho | First 5 Authors: Jian-Fa Wang, Jian-Fa Wang, , , | Summary: We present observations of HCN J=4-3 and HCO^+ J=4-3 lines obtained with the James Clerk Maxwell Telescope as part of the MALATANG survey, combined with archival HCN J=1-0 and HCO^+ J=1-0 data from the Green Bank Telescope, to study […]
Kavli Affiliate: Jing Wang | First 5 Authors: Wen-Hao Bian, Wen-Hao Bian, , , | Summary: We systematically investigate how static symmetry-breaking perturbations and dynamic Floquet terms via a polarized light manipulate the topological phase transitions in the two-dimensional quadratic-band-crossing-point (QBCP) materials. The Berry curvature shows distinct behavior in such two situations. It is linearly […]
Kavli Affiliate: Ke Wang | First 5 Authors: Yiyao Wang, Yiyao Wang, , , | Summary: Direct volume rendering (DVR) is a fundamental technique for visualizing volumetric data, where transfer functions (TFs) play a crucial role in extracting meaningful structures. However, designing effective TFs remains unintuitive due to the semantic gap between user intent and […]
Kavli Affiliate: Ke Wang | First 5 Authors: Fanhao Shen, Yujie Ji, Debin Xiang, Yanzhe Wang, Ke Wang | Summary: Quantum random access memory (QRAM) enables efficient classical data access for quantum computers — a prerequisite for many quantum algorithms to achieve quantum speedup. Despite various proposals, the experimental realization of QRAM remains largely unexplored. […]
Kavli Affiliate: Jing Wang | First 5 Authors: Ruiming Chen, Junming Yang, Shiyu Xia, Xu Yang, Jing Wang | Summary: CLIP (Contrastive Language-Image Pre-training) has attracted widespread attention for its multimodal generalizable knowledge, which is significant for downstream tasks. However, the computational overhead of a large number of parameters and large-scale pre-training poses challenges of […]
