Surface Reconstruction Limited Conductivity in Block-Copolymer Li Battery Electrolytes

Posted by klaurent Cornell

Kavli Affiliate: Ulrich Wiesner | Summary:Solid polymer electrolytes for lithium batteries promise improvements in safety and energy density if their conductivity can be increased. Nanostructured block copolymer electrolytes specifically have the potential to provide both good ionic conductivity and good mechanical properties. This study shows that the previously neglected nanoscale composition of the polymer electrolyte […]

Catalogues of Active Galactic Nuclei From Gaia and unWISE Data

Posted by klaurent Cambridge

Kavli Affiliate: R. G. McMahon | Summary:We present two catalogues of active galactic nucleus (AGN) candidates selected from the latest data of two all-sky surveys — Data Release 2 (DR2) of the emphGaia mission and the unWISE catalogue of the emphWide-field Infrared Survey Explorer (emphWISE). We train a random forest classifier to predict the probability […]

Microwave multiplexing on the Keck Array

Posted by klaurent Stanford

Kavli Affiliate: Ethan Karpel | Summary:We describe an on-sky demonstration of a microwave-multiplexing readout system in one of the receivers of the Keck Array, a polarimetry experiment observing the cosmic microwave background at the South Pole. During the austral summer of 2018-2019, we replaced the time-division multiplexing readout system with microwave-multiplexing components including superconducting microwave […]

Deep Learning for Estimating Synaptic Health of Primary Neuronal Cell Culture

Posted by klaurent Oxford

Kavli Affiliate: Noel Buckley | Summary:Understanding the morphological changes of primary neuronal cells induced by chemical compounds is essential for drug discovery. Using the data from a single high-throughput imaging assay, a classification model for predicting the biological activity of candidate compounds was introduced. The image recognition model which is based on deep convolutional neural […]

Independence Testing for Temporal Data

Posted by dbos Berkeley

Kavli Affiliate: Ting Xu | First 5 Authors: Cencheng Shen, Jaewon Chung, Ronak Mehta, Ting Xu, Joshua T. Vogelstein | Summary: Temporal data are increasingly prevalent in modern data science. A fundamental question is whether two time-series are related or not. Existing approaches often have limitations, such as relying on parametric assumptions, detecting only linear […]

Design and experimental demonstration of a laser modulation system for future gravitational-wave detectors

Posted by klaurent Tokyo

Kavli Affiliate: Takaaki Kajita | Summary:Detuning the signal-recycling cavity length from a cavity resonance significantly improves the quantum noise beyond the standard quantum limit, while there is no km-scale gravitational-wave detector successfully implemented the technique. The detuning technique is known to introduce great excess noise, and such noise can be reduced by a laser modulation […]
