Kavli Affiliate: Leon Balents | First 5 Authors: Bin Gao, Tong Chen, Chunxiao Liu, Mason L. Klemm, Shu Zhang | Summary: In magnetically ordered insulators, elementary quasiparticles manifest as spin waves – collective motions of localized magnetic moments propagating through the lattice – observed via inelastic neutron scattering. In effective spin-1/2 systems where geometric frustrations […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Saining Zhang, Baijun Ye, Xiaoxue Chen, Yuantao Chen, Zongzheng Zhang | Summary: Robust and realistic rendering for large-scale road scenes is essential in autonomous driving simulation. Recently, 3D Gaussian Splatting (3D-GS) has made groundbreaking progress in neural rendering, but the general fidelity of large-scale road scene renderings […]
Kavli Affiliate: Mark Bowick | First 5 Authors: John Berezney, Sattvic Ray, Itamar Kolvin, Mark Bowick, Seth Fraden | Summary: We use the chaotic flows generated by a microtubule-based active fluid to assemble self-binding actin filaments into a thin elastic sheets. Starting from a uniformly dispersed state, active flows drive the motion of actin filaments, […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Yang Wang, Danni Wang, Liting Zhong, Yi Zhou, Qing Wang | Summary: Photoacoustic tomography (PAT) enables non-invasive cross-sectional imaging of biological tissues, but it fails to map the spatial variation of speed-of-sound (SOS) within tissues. While SOS is intimately linked to density and elastic modulus of tissues, […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Zeyu Wang, Qitong Wang, Xiaoxing Cheng, Peng Wang, Themis Palpanas | Summary: Graph-based indexes have been widely employed to accelerate approximate similarity search of high-dimensional vectors. However, the performance of graph indexes to answer different queries varies vastly, leading to an unstable quality of service for downstream […]

Kavli Affiliate: Yi Zhou | First 5 Authors: Rui Yang, Jiahao Zhu, Jianping Man, Hongze Liu, Li Fang | Summary: Knowledge graph completion (KGC) focuses on identifying missing triples in a knowledge graph (KG) , which is crucial for many downstream applications. Given the rapid development of large language models (LLMs), some LLM-based methods are […]
Kavli Affiliate: Yi Zhou | First 5 Authors: Lili Du, Yi Zhou, , , | Summary: In the previous work [Interfaces Free Bound., 19, 351-369, 2017], de Queiroz and Shahgholian investigated the regularity of the solution to the obstacle problem with singular logarithmic forcing term begin{equation*} -Delta u = log u , chi_{{u>0}} quad text{in} […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Baoping Cheng, Peng Lei, Xiaoyan Xie, Tao Fu, Yukun Zhang | Summary: To improve the quality of experience (QoE) in video communication over lossy networks, this paper presents a transmission method that jointly optimizes buffer delay and Hybrid Automatic Repeat request (HARQ), referred to as BD-HARQ. This […]
Kavli Affiliate: Cheng Peng | First 5 Authors: Yiqian Chen, Lang Cheng, Peng Wang, Haitang Yang, | Summary: In this paper, we study the observational signatures of traversable Simpson-Visser wormholes illuminated by luminous celestial spheres and orbiting hot spots. We demonstrate that when light sources and observers are on the same side of the wormholes, […]
