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 | 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 significantly deeper than previous photographic surveys. Our median/95th percentile cumulative exposure time per field is 58.1/86.8 hours, and […]

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: Ke Wang | First 5 Authors: Ke Wang, Ke Wang, , , | Summary: Pair-density-wave (PDW) states — exotic superconductors with spatially modulated order — are a long-sought-after phase of quantum materials, with the potential to unravel the mysteries of high-$T_c$ cuprates and other strongly correlated superconductors. Yet, surprisingly, a key signature of […]

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 […]

Kavli Affiliate: Luis C. Ho | First 5 Authors: Xi Yan, Xi Yan, , , | Summary: We report the first robust evidence for a co-spatial sub-parsec acceleration and collimation zone (ACZ) in the twin jets of the nearby low-luminosity active galactic nucleus (LLAGN) NGC 4261. This result is derived from multifrequency Very Long Baseline […]

Kavli Affiliate: Xian Chen | First 5 Authors: Chenbo Zhang, Xian Chen, , , | Summary: Composition-temperature phase diagrams are crucial for designing ferroelectric materials, however predicting them accurately remains challenging due to limited phase transformation data and the constraints of conventional methods. Here, we utilize natural language processing (NLP) to text-mine 41,597 research articles, […]

Kavli Affiliate: Xian Chen | First 5 Authors: Ka Hung Chan, Xinyue Huang, Nobumichi Tamura, Xian Chen, | Summary: Understanding the grain morphology, orientation distribution, and crystal structure of nanocrystals is essential for optimizing the mechanical and physical properties of functional materials. Synchrotron X-ray Laue microdiffraction is a powerful technique for characterizing crystal structures and […]

Kavli Affiliate: Huawei Zhang | Summary:We present a catalog of 8,440 candidate very metal-poor (VMP; [Fe/H] < -2.0) main-sequence turn-off (MSTO) and red giant stars in the Milky Way, identified from low-resolution spectra in LAMOST DR10. More than 7,000 of these candidates are brighter than G ~ 16, making them excellent targets for high-resolution spectroscopic […]
