Kavli Affiliate: Xiang Zhang | First 5 Authors: Natasha Hurley-Walker, Timothy J. Galvin, Stefan W. Duchesne, Xiang Zhang, John Morgan | Summary: We describe a new low-frequency wideband radio survey of the southern sky. Observations covering 72 – 231 MHz and Declinations south of $+30^circ$ have been performed with the Murchison Widefield Array "extended" Phase […]

Kavli Affiliate: Alessandra Lanzara | First 5 Authors: Maximilian Huber, Yi Lin, Nicholas Dale, Renee Sailus, Sefaattin Tongay | Summary: Charge density waves (CDW) are states of broken symmetry with a periodic modulation of charge and lattice typically leading to the opening of a gap in the band structure. In the model CDW system 1T-TiSe$_2$ […]

Kavli Affiliate: Feng Wang | First 5 Authors: Wen Feng, Wang Mei, Hu Xiaojie, , | Summary: Object detection is one of the most significant aspects of computer vision, and it has achieved substantial results in a variety of domains. It is worth noting that there are few studies focusing on slender object detection. CNNs […]

Kavli Affiliate: Ting Xu | First 5 Authors: Le Ma, Hejin Huang, Peter Ercius, Alfredo Alexander-Katz, Ting Xu | Summary: Co-assembly of inorganic nanoparticles (NPs) and nanostructured polymer matrix represents an intricate interplay of enthalpic or entropic forces. Particle size largely affects the phase behavior of the nanocomposite. Theoretical studies indicate that new morphologies would […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Long Lan, Xiao Teng, Haoang Chi, Xiang Zhang, | Summary: Unsupervised person re-identification is a challenging and promising task in the computer vision. Nowadays unsupervised person re-identification methods have achieved great improvements by training with pseudo labels. However, the appearance and label noise are less explicitly studied […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Long Lan, Xiao Teng, Jing Zhang, Xiang Zhang, Dacheng Tao | Summary: Unsupervised person re-identification is a challenging and promising task in computer vision. Nowadays unsupervised person re-identification methods have achieved great progress by training with pseudo labels. However, how to purify feature and label noise is […]

Kavli Affiliate: Alex Zettl | First 5 Authors: Dillan J. Chang, Colum M. O’Leary, Cong Su, Salman Kahn, Alex Zettl | Summary: We report the development of deep learning coherent electron diffractive imaging at sub-angstrom resolution using convolutional neural networks (CNNs) trained with only simulated data. We experimentally demonstrate this method by applying the trained […]

Kavli Affiliate: Xiang Zhang | First 5 Authors: Wenju Zhang, Xiang Zhang, Qing Liao, Long Lan, Mengzhu Wang | Summary: Nuclear norm maximization has shown the power to enhance the transferability of unsupervised domain adaptation model (UDA) in an empirical scheme. In this paper, we identify a new property termed equity, which indicates the balance […]

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Ann Rutt, Jimmy-Xuan Shen, Matthew Horton, Jiyoon Kim, Jerry Lin | Summary: Multivalent batteries are an energy storage technology with the potential to surpass lithium-ion batteries, however their performance has been limited by the low voltages and poor solid-state ionic mobility of available cathodes. A computational […]

Kavli Affiliate: Eli Yablonovitch | First 5 Authors: Sri Krishna Vadlamani, Tianyao Patrick Xiao, Eli Yablonovitch, , | Summary: There has been a recent surge of interest in physics-based solvers for combinatorial optimization problems. We present a dynamical solver for the Ising problem that is comprised of a network of coupled parametric oscillators and show […]
