Rapid learning of neural circuitry from holographic ensemble stimulation enabled by model-based compressed sensing

Posted by klaurent October 2, 2023October 16, 2023Columbia

Kavli Affiliate: Liam Paninski | Authors: Marcus A. Triplett, Marta Gajowa, Benjamin Antin, Masato Sadahiro, Hillel Adesnik and Liam Paninski | Summary: Abstract Discovering how neural computations are implemented in the cortex at the level of monosynaptic connectivity requires probing for the existence of synapses from possibly thousands of presynaptic candidate neurons. Two-photon optogenetics has […]

Hot electron diffusion, microwave noise, and piezoresistivity in Si from first principles

Posted by dbos October 2, 2023Caltech

Kavli Affiliate: Austin J. Minnich | First 5 Authors: Benjamin Hatanpää, Austin J. Minnich, , , | Summary: Ab-initio calculations of charge transport properties in materials without adjustable parameters have provided microscopic insights into electron-phonon interactions which govern charge transport properties. Other transport properties such as the diffusion coefficient provide additional microscopic information and are […]

SpinPSO: An agent-based optimization workflow for identifying global noncollinear magnetic ground-states from first-principles

Posted by klaurent October 2, 2023October 16, 2023Berkeley

Kavli Affiliate: Kristin A. Persson | First 5 Authors: Guy C. Moore, Matthew K. Horton, Kristin A. Persson, , | Summary: We propose and implement a novel hybrid meta-heuristic optimization algorithm for the identification of non-collinear global ground-states in magnetic systems. The inputs to this optimization scheme are directly from non-collinear density functional theory (DFT), […]
