Solving Complex Nanostructures With Ptychographic Atomic Electron Tomography

Posted by klaurent Berkeley

Kavli Affiliate: Alex Zettl | First 5 Authors: Philipp M Pelz, Sinead Griffin, Scott Stonemeyer, Derek Popple, Hannah Devyldere | Summary: Transmission electron microscopy (TEM) is a potent technique for the determination of three-dimensional atomic scale structure of samples in structural biology and materials science. In structural biology, three-dimensional structures of proteins are routinely determined […]

ATOMS: ALMA Three-millimeter Observations of Massive Star-forming regions — XI. From inflow to infall in hub-filament systems

Posted by klaurent Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Jian-Wen Zhou, Tie Liu, Neal J. Evans II, Guido Garay, Paul F. Goldsmith | Summary: We investigate the presence of hub-filament systems in a large sample of 146 active proto-clusters, using H$^{13}$CO$^{+}$ J=1-0 molecular line data obtained from the ATOMS survey. We find that filaments are ubiquitous […]

Self-Supervised Contrastive Pre-Training For Time Series via Time-Frequency Consistency

Posted by klaurent Berkeley

Kavli Affiliate: Xiang Zhang | First 5 Authors: Xiang Zhang, Ziyuan Zhao, Theodoros Tsiligkaridis, Marinka Zitnik, | Summary: Pre-training on time series poses a unique challenge due to the potential mismatch between pre-training and target domains, such as shifts in temporal dynamics, fast-evolving trends, and long-range and short cyclic effects, which can lead to poor […]

The Atari Disk, a Metal-Poor Stellar Population in the Disk System of the Milky Way

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Mohammad K. Mardini, Anna Frebel, Anirudh Chiti, Yohai Meiron, Kaley V. Brauer | Summary: We have developed a chemo-dynamical approach to assign 36,010 metal-poor SkyMapper stars to various Galactic stellar populations. Using two independent techniques (velocity and action space behavior), $Gaia$ EDR3 astrometry, and photometric metallicities, we […]

Adaptive Algorithm for Quantum Amplitude Estimation

Posted by klaurent Berkeley

Kavli Affiliate: Feng Wang | First 5 Authors: Yunpeng Zhao, Haiyan Wang, Kuai Xu, Yue Wang, Ji Zhu | Summary: Quantum amplitude estimation is a key sub-routine of a number of quantum algorithms with various applications. We propose an adaptive algorithm for interval estimation of amplitudes. The quantum part of the algorithm is based only […]

Cold Gas Reservoirs of Low- and High-mass Central Galaxies Differ in Response to Active Galactic Nucleus Feedback

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Hong Guo, Michael G. Jones, Jing Wang, , | Summary: The growth of supermassive black holes, especially the associated state of active galactic nuclei (AGNs), is generally believed to be the key step in regulating star formation in massive galaxies. As the fuel of star formation, the […]
