Direct ultrafast parametric amplification pumped by a picosecond thin-disk laser

Posted by klaurent Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Jing Wang, Peng Yuan, Dongfang Zhang, Guoqiang Xie, Kainan Xiong | Summary: Optical quadratic nonlinearity is ultrafast in nature, while parametric interaction usually manifests only the broadband characteristic. Enormous progress has been made toward broadband phase-matching for parametric amplification and wide applications. In existing devices of broadband […]

A Lightweight Space-based Solar Power Generation and Transmission Satellite

Posted by klaurent Caltech

Kavli Affiliate: Ali Hajimiri | Summary:We propose a novel design for a lightweight, high-performance space-based solar power array combined with power beaming capability for operation in geosynchronous orbit and transmission of power to Earth. We use a modular configuration of small, repeatable unit cells, called tiles, that each individually perform power collection, conversion, and transmission. […]

Alexa Teacher Model: Pretraining and Distilling Multi-Billion-Parameter Encoders for Natural Language Understanding Systems

Posted by klaurent Caltech

Kavli Affiliate: Thomas Rosenbaum| First 5 Authors: Jack FitzGerald, Jack FitzGerald, , , | Summary:We present results from a large-scale experiment on pretraining encoders with non-embedding parameter counts ranging from 700M to 9.3B, their subsequent distillation into smaller models ranging from 17M-170M parameters, and their application to the Natural Language Understanding (NLU) component of a […]

Synaptic vesicle proteins and ATG9A self-organize in distinct vesicle phases within synapsin condensates

Posted by klaurent Yale

Kavli Affiliate: Pietro DeCamilli | Authors: Daehun Park, Yumei Wu, Aaron Baublis and Pietro De Camilli | Summary: Ectopic expression in fibroblasts of synapsin 1 and synaptophysin is sufficient to generate condensates of vesicles highly reminiscent of synaptic vesicle (SV) clusters and with liquid-like properties. We show that unlike synaptophysin, other major integral SV membrane […]

Angling for x-ray pulsar geometry with polarimetry

Posted by klaurent MIT

Kavli Affiliate: Herman L. Marshall | First 5 Authors: Victor Doroshenko, Juri Poutanen, Sergey Tsygankov, Valery Suleimanov, Matteo Bachetti | Summary: Using observations of X-ray pulsar Her X-1 by the Imaging X-ray Polarimetry Explorer, we report on a highly significant detection of the polarization signal from an accreting neutron star. The observed degree of the […]

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 […]

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 […]
