Functional network properties derived from widefield calcium imaging differ with wakefulness and across cell type

Posted by klaurent Yale

Kavli Affiliate: Michael Crair | Authors: David O’Connor, Francesca Mandino, Xilin Shen, Corey Horien, Xinxin Ge, Peter Herman, Michael Crair, Xenophon Papademetris, Evelyn MR Lake and Robert Todd Constable | Summary: To improve bench-to-bedside translation, it is integral that knowledge flow bidirectionally from – animal models to humans, and vice versa. This will be facilitated […]

Possibilities and Limitations of Kinematically Identifying Stars from Accreted Ultra-Faint Dwarf Galaxies

Posted by klaurent MIT

Kavli Affiliate: Anna Frebel | First 5 Authors: Kaley Brauer, Hillary D. Andales, Alexander P. Ji, Anna Frebel, Mohammad K. Mardini | Summary: The Milky Way has accreted many ultra-faint dwarf galaxies (UFDs), and stars from these galaxies can be found throughout our Galaxy today. Studying these stars provides insight into galaxy formation and early […]

An entanglement perspective on the quantum approximate optimization algorithm

Posted by klaurent Berkeley

Kavli Affiliate: Joel E. Moore | First 5 Authors: Maxime Dupont, Nicolas Didier, Mark J. Hodson, Joel E. Moore, Matthew J. Reagor | Summary: Many quantum algorithms seek to output a specific bitstring solving the problem of interest–or a few if the solution is degenerate. It is the case for the quantum approximate optimization algorithm […]

ET White Paper: To Find the First Earth 2.0

Posted by klaurent Peking

Kavli Affiliate: Subo Dong | First 5 Authors: Jian Ge, Hui Zhang, Weicheng Zang, Hongping Deng, Shude Mao | Summary: We propose to develop a wide-field and ultra-high-precision photometric survey mission, temporarily named "Earth 2.0 (ET)". This mission is designed to measure, for the first time, the occurrence rate and the orbital distributions of Earth-sized […]

Sustained unidirectional rotation of a self-organized DNA rotor on a nanopore

Posted by dbos Delft

Kavli Affiliate: Cees Dekker | First 5 Authors: Xin Shi, Anna-Katharina Pumm, Jonas Isensee, Wenxuan Zhao, Daniel Verschueren | Summary: Flow-driven rotary motors drive functional processes in human society such as windmills and water wheels. Although examples of such rotary motors also feature prominently in cell biology, their synthetic construction at the nanoscale has thus […]
