Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, , , , | Summary: We show that every codimension one partially hyperbolic diffeomorphism must support on $mathbb{T}^{n}$. It is locally uniquely integrable and derived from a linear codimension one Anosov diffeomorphism. Moreover, this system is intrinsically ergodic, and the A. Katok’s conjecture about the […]
Kavli Affiliate: Paul Alivisatos | First 5 Authors: Jason J. Calvin, Amanda S. Brewer, Michelle F. Crook, Tierni M. Kaufman, A. Paul Alivisatos | Summary: Surface energy is a fundamental property of materials and is particularly important in describing nanomaterials where atoms or molecules at the surface constitute a large fraction of the material. Traditionally, […]
Kavli Affiliate: Paul Alivisatos | Summary:Surface energy is a fundamental property of materials and is particularly important in describing nanomaterials where atoms or molecules at the surface constitute a large fraction of the material. Traditionally, surface energy is considered to be a positive quantity, where atoms or molecules at the surface are less thermodynamically stable […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Tianchun Wan, Wei Cheng, Dongsheng Luo, Wenchao Yu, Jingchao Ni | Summary: Personalized Federated Learning (PFL) which collaboratively trains a federated model while considering local clients under privacy constraints has attracted much attention. Despite its popularity, it has been observed that existing PFL approaches result in sub-optimal […]
Kavli Affiliate: Alex Zettl | Summary:Four-dimensional scanning transmission electron microscopy (4D-STEM) has recently gained widespread attention for its ability to image atomic electric fields with sub-Ångstrom spatial resolution. These electric field maps represent the integrated effect of the nucleus, core electrons and valence electrons, and separating their contributions is non-trivial. In this paper, we utilized […]
Kavli Affiliate: Xiang Zhang | First 5 Authors: Junjie Xu, Enyan Dai, Xiang Zhang, Suhang Wang, | Summary: Graph neural networks (GNNs) have achieved great success in various graph problems. However, most GNNs are Message Passing Neural Networks (MPNNs) based on the homophily assumption, where nodes with the same label are connected in graphs. Real-world […]
Kavli Affiliate: Feng Wang | First 5 Authors: Daiheng Gao, Yuliang Xiu, Kailin Li, Lixin Yang, Feng Wang | Summary: Hand, the bearer of human productivity and intelligence, is receiving much attention due to the recent fever of digital twins. Among different hand morphable models, MANO has been widely used in vision and graphics community. […]
Kavli Affiliate: Paul Alivisatos | Summary:Semiconducting, core-shell nanocrystals (NCs) are promising building blocks for the construction of higher dimensional artificial nanostructures using oriented attachment. However, the assembly and epitaxial attachment steps critical to this construction introduce disorder and defects which inhibit the observation of desirable emergent electronic phenomena. Consequently, understanding defect formation and remediation in […]
Kavli Affiliate: Feng Wang | First 5 Authors: Feng Wang, Manling Li, Xudong Lin, Hairong Lv, Alexander G. Schwing | Summary: Recent advances in pre-training vision-language models like CLIP have shown great potential in learning transferable visual representations. Nonetheless, for downstream inference, CLIP-like models suffer from either 1) degraded accuracy and robustness in the case […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Jinwoong Hwang, Yeongrok Jin, Canxun Zhang, Tiancong Zhu, Kyoo Kim | Summary: The spontaneous formation of electronic orders is a crucial element for understanding complex quantum states and engineering heterostructures in two-dimensional materials. We report a novel $sqrt{19}timessqrt{19}$ charge order in few-layer thick 1T-TaTe$_2$ transition metal […]
