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: 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 […]
Kavli Affiliate: Ran Wang | First 5 Authors: Yuxuan Wu, Tao Wang, Daizhong Liu, Qinghua Tan, Luis C. Ho | Summary: A significant population of quasars have been found to exist within the first Gyr of cosmic time. Most of them have high black hole (BH) masses ($M_{rm BH} sim 10^{8-10} M_{odot}$) with an elevated […]
Kavli Affiliate: Subo Dong | First 5 Authors: Evan Jennerjahn, Michael A. Tucker, Benjamin J. Shappee, Christopher S. Kochanek, Subo Dong | Summary: The ASAS-SN Low Surface Brightness Survey utilizes the $sim7$ years of g-band CCD data from ASAS-SN (The All-Sky Automated Survey for Supernovae) to create stacked images of the entire sky. It is […]
Kavli Affiliate: Ke Wang | First 5 Authors: Ke Wang, Qijin Chen, Rufus Boyack, K. Levin, | Summary: We study the superfluid density $n_s(T)$ of pair-density-wave (PDW) superconductors; this determines where they are unstable and establishes signatures of their unusual order. Here we compute $n_s(T)$ for the 2D unidirectional PDW superconducting phases that emerge from […]
Kavli Affiliate: Luis C. Ho | First 5 Authors: Xi Yan, Lang Cui, Kazuhiro Hada, Sandor Frey, Ru-sen Lu | Summary: We study the acceleration and collimation of the two-sided jets in the nearby low-luminosity active galactic nucleus NGC 4261 (3C 270) using archival multifrequency, multi-epoch Very Long Baseline Array data. By applying multiple analysis […]
