Kavli Affiliate: Jia Liu | First 5 Authors: Jia Liu, Wenjie Xuan, Yuhang Gan, Juhua Liu, Bo Du | Summary: Existing deep learning-based change detection methods try to elaborately design complicated neural networks with powerful feature representations, but ignore the universal domain shift induced by time-varying land cover changes, including luminance fluctuations and season changes […]
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: Yi Zhou | First 5 Authors: Shaocong Ma, Ziyi Chen, Yi Zhou, Kaiyi Ji, Yingbin Liang | Summary: Conventional machine learning applications typically assume that data samples are independently and identically distributed (i.i.d.). However, practical scenarios often involve a data-generating process that produces highly dependent data samples, which are known to heavily bias […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Simultaneously sensing and resolving the position of measurands along an optical fiber enables numerous opportunities, especially for application in environments where massive sensor deployment is not feasible. Despite significant progress in techniques based on round-trip time-of-flight measurements, the […]
Kavli Affiliate: Alireza Marandi | First 5 Authors: Luis Costa, Zhongwen Zhan, Alireza Marandi, , | Summary: Fiber optic distributed sensors typically demand bidirectional propagation in optical fibers to localize each point of measurement. This imposes barriers to their deployment in long-haul, amplified telecommunication links and prevents massive range enhancement through in-line amplification, due to […]
Kavli Affiliate: Michael F. Crommie | First 5 Authors: Jinwoong Hwang, Kyoo Kim, Canxun Zhang, Tiancong Zhu, Charlotte Herbig | Summary: Monolayers of two-dimensional van der Waals materials exhibit novel electronic phases distinct from their bulk due to the symmetry breaking and reduced screening in the absence of the interlayer coupling. In this work, we […]
Kavli Affiliate: Kerry J. Vahala | First 5 Authors: Joel Guo, Charles A. McLemore, Chao Xiang, Dahyeon Lee, Lue Wu | Summary: Lasers with hertz-level linewidths on timescales up to seconds are critical for precision metrology, timekeeping, and manipulation of quantum systems. Such frequency stability typically relies on bulk-optic lasers and reference cavities, where increased […]
Kavli Affiliate: Craig Hogan | First 5 Authors: Craig Hogan, , , , | Summary: Quantum field theory, which is generally used to describe the origin of large-scale gravitational perturbations during cosmic inflation, has been shown to omit an important physical effect in curved space-time, the nonlocal entanglement among quantized modes from their gravitational effect […]
Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, , , , | Summary: We point out that some questions in quantum field theory are undecidable in a precise mathematical sense. More concretely, it will be demonstrated that there is no algorithm answering whether a given 2d supersymmetric Lagrangian theory breaks supersymmetry or not. […]
