Kavli Affiliate: Lijing Shao | First 5 Authors: Zihang Wang, Lijing Shao, , , | Summary: The cosmological constant is not necessarily small in the early universe. If a scalar field obtains a vacuum expectation value after a phase transition (PT), a possibly large cosmological constant could present before PT. The early cosmological constant (ECC) […]
Kavli Affiliate: Subo Dong | First 5 Authors: Andrew Gould, Youn Kil Jung, Kyu-Ha Hwang, Subo Dong, Michael D. Albrow | Summary: We complete the survey for finite-source/point-lens (FSPL) giant-source events in 2016-2019 KMTNet microlensing data. The 30 FSPL events show a clear gap in Einstein radius, $9,mu{rm as}<theta_{rm E} <26,mu{rm as}$, which is consistent […]
Kavli Affiliate: Ke Wang | First 5 Authors: Wenhui Ren, Weikang Li, Shibo Xu, Ke Wang, Wenjie Jiang | Summary: Quantum computing promises to enhance machine learning and artificial intelligence. Different quantum algorithms have been proposed to improve a wide spectrum of machine learning tasks. Yet, recent theoretical works show that, similar to traditional classifiers […]
Kavli Affiliate: Li Xin Li | First 5 Authors: Qiuhong Shen, Lei Qiao, Jinyang Guo, Peixia Li, Xin Li | Summary: Unsupervised learning has been popular in various computer vision tasks, including visual object tracking. However, prior unsupervised tracking approaches rely heavily on spatial supervision from template-search pairs and are still unable to track objects […]
Kavli Affiliate: Ran Wang | First 5 Authors: Jianan Li, Bram P. Venemans, Fabian Walter, Roberto Decarli, Ran Wang | Summary: We present high spatial resolution (0.4", 2.2kpc) observations of the CO(6-5), CO(7-6) and [CI] lines and dust continuum emission from the interstellar medium in the host galaxy of the quasar J0305$-$3150 at $z=6.6$. These, […]
Kavli Affiliate: Ke Wang | First 5 Authors: Yao Yao, Bin Liu, Haoxun He, Dakui Sheng, Ke Wang | Summary: Input features play a crucial role in the predictive performance of DNN-based industrial recommender systems with thousands of categorical and continuous fields from users, items, contexts, and their interactions. Noisy features and inappropriate embedding dimension […]
Kavli Affiliate: Pau Amaro Seoane | First 5 Authors: Robert Stein, Simeon Reusch, Anna Franckowiak, Marek Kowalski, Jannis Necker | Summary: The Zwicky Transient Transient Facility (ZTF) performs a systematic neutrino follow-up program, searching for optical counterparts to high-energy neutrinos with dedicated Target-of-Opportunity (ToO) observations. Since first light in March 2018, ZTF has taken prompt […]
Kavli Affiliate: Ke Wang | First 5 Authors: Yuri A. Genenko, Sergey Zhukov, Maohua Zhang, Ke Wang, Jurij Koruza | Summary: Ferroelectrics are multifunctional smart materials finding applications in sensor technology, micromechanical actuation, digital information storage etc. Their most fundamental property is the ability of polarization switching under applied electric field. In particular, understanding of […]
Kavli Affiliate: Jing Wang | First 5 Authors: Quecheng Qiu, Shunyi Yao, Jing Wang, Jun Ma, Guangda Chen | Summary: Existing navigation policies for autonomous robots tend to focus on collision avoidance while ignoring human-robot interactions in social life. For instance, robots can pass along the corridor safer and easier if pedestrians notice them. Sounds […]
