Discovering group dynamics in coordinated time series via hierarchical recurrent switching-state models

Posted by dbos MIT

Kavli Affiliate: Eric Miller | First 5 Authors: Michael T. Wojnowicz, Kaitlin Gili, Preetish Rath, Eric Miller, Jeffrey Miller | Summary: We seek a computationally efficient model for a collection of time series arising from multiple interacting entities (a.k.a. "agents"). Recent models of spatiotemporal patterns across individuals fail to incorporate explicit system-level collective behavior that […]

Discovering group dynamics in synchronous time series via hierarchical recurrent switching-state models

Posted by klaurent MIT

Kavli Affiliate: Eric Miller | First 5 Authors: Michael Wojnowicz, Preetish Rath, Eric Miller, Jeffrey Miller, Clifford Hancock | Summary: We seek to model a collection of time series arising from multiple entities interacting over the same time period. Recent work focused on modeling individual time series is inadequate for our intended applications, where collective […]

Modeling the wavelength dependence of pixel response non-uniformity of a CCD sensor

Posted by dbos Peking

Kavli Affiliate: Hu Zhan | First 5 Authors: Zun Luo, Wei Du, Baocun Chen, Xianmin Meng, Hu Zhan | Summary: Precision measurements in astronomy require stringent control of systematics such as those arising from imperfect correction of sensor effects. In this work, we develop a parametric method to model the wavelength dependence of pixel response […]

On the Scarcity of Dense Cores ($n>10^{5}$ cm$^{-3}$) in High Latitude Planck Galactic Cold Clumps

Posted by dbos Peking

Kavli Affiliate: Ke Wang | First 5 Authors: Fengwei Xu, Ke Wang, Tie Liu, David Eden, Xunchuan Liu | Summary: High-latitude ($|b|>30^{circ}$) molecular clouds have virial parameters that exceed 1, but whether these clouds can form stars has not been studied systematically. Using JCMT SCUBA-2 archival data, we surveyed 70 fields that target high-latitude Planck […]

Luminosity Functions of the Host Galaxies of Supernova

Posted by dbos Tokyo

Kavli Affiliate: Naoki Yasuda | First 5 Authors: Zhuoxi Liang, Nao Suzuki, Mamoru Doi, Masayuki Tanaka, Naoki Yasuda | Summary: We present the luminosity functions and stellar mass functions of supernova (SN) host galaxies and test if they differ from the functions of normal field galaxies. We utilize homogeneous samples consisting of 273 SNe Ia […]

An experimental census of retrons for DNA production and genome editing

Posted by dbos UCSF

Kavli Affiliate: Seth Shipman | Authors: Asim G. Khan, Matías Rojas-Montero, Alejandro González-Delgado, Santiago C. Lopez, Rebecca F. Fang and Seth L. Shipman | Summary: Abstract Retrons are bacterial immune systems that use reverse transcribed DNA as a detector of phage infection. They are also increasingly deployed as a component of biotechnology. For genome editing, […]

Geometry of anisotropic contextual interactions in the visual cortex places fundamental limits on spatial vision

Posted by klaurent Yale

Kavli Affiliate: Anirvan Nandy | Authors: Mitchell P. Morton, Sachira Denagamage, Nyomi V. Hudson and Anirvan S. Nandy | Summary: Crowding, the impaired ability to accurately recognize a target stimulus among distractors, is a major bottleneck in visual perception. The spatial configuration of distractors in relation to the target profoundly influences perceptual fidelity. Notably, when […]
