Cortical surface electrical potentials are composed of multiple bandlimited frequency components, including high-gamma

Posted by klaurent July 23, 2022August 1, 2022UCSF

Kavli Affiliate: Kristofer Bouchard, Edward Chang | Authors: Jesse A Livezey, Ahyeon Hwang, Kseniya Usovich, Maximilian Dougherty, Edward F Chang and Kristofer E Bouchard | Summary: A common challenge in neuroscience is how to decompose noisy, multi-source signals measured in experiments into biophysically interpretable components. Analysis of cortical surface electrical potentials (CSEPs) measured using electrocorticography […]

Suboptimal phenotypic reliability impedes reproducible human neuroscience

Posted by klaurent July 23, 2022August 1, 2022Hopkins

Kavli Affiliate: Joshua Vogelstein | Authors: Aki Nikolaidis, Andrew An Chen, Xiaoning He, Russell Shinohara, Joshua Vogelstein, Michael Milham and Haochang Shou | Summary: Biomarkers of behavior and psychiatric illness for cognitive and clinical neuroscience remain out of reach. Suboptimal reliability of biological measurements, such as functional magnetic resonance imaging (fMRI), is increasingly cited as […]

Marginal Bayesian Statistics Using Masked Autoregressive Flows and Kernel Density Estimators with Examples in Cosmology

Posted by klaurent July 23, 2022Cambridge

Kavli Affiliate: George Efstathiou | First 5 Authors: Harry Bevins, Will Handley, Pablo Lemos, Peter Sims, Eloy de Lera Acedo | Summary: Cosmological experiments often employ Bayesian workflows to derive constraints on cosmological and astrophysical parameters from their data. It has been shown that these constraints can be combined across different probes such as Planck […]

Measurements of the branching fraction, isospin asymmetry, and lepton-universality ratio in $B to J/ψK$ decays at Belle II

Posted by klaurent Tokyo

Kavli Affiliate: T. Higuchi | First 5 Authors: Belle II Collaboration, F. Abudinén, I. Adachi, R. Adak, K. Adamczyk | Summary: We report a study of $B to J/psi(ell^{+}ell^{-})K$ decays, where $ell$ represents an electron or a muon, using $e^{+}e^{-}$ collisions at the $Upsilon(4S)$ resonance. The data were collected by the Belle II experiment at […]

Two-Stage Fine-Tuning: A Novel Strategy for Learning Class-Imbalanced Data

Posted by klaurent July 22, 2022Peking

Kavli Affiliate: Jing Wang | First 5 Authors: Taha ValizadehAslani, Yiwen Shi, Jing Wang, Ping Ren, Yi Zhang | Summary: Classification on long-tailed distributed data is a challenging problem, which suffers from serious class-imbalance and hence poor performance on tail classes with only a few samples. Owing to this paucity of samples, learning on the […]

Requirements for a processing-node quantum repeater on a real-world fiber grid

Posted by dbos July 21, 2022Delft

Kavli Affiliate: Stephanie Wehner | First 5 Authors: Guus Avis, Francisco Ferreira da Silva, Tim Coopmans, Axel Dahlberg, Hana Jirovská | Summary: We numerically study the distribution of entanglement between the Dutch cities of Delft and Eindhoven realized with a processing-node quantum repeater and determine minimal hardware requirements for verifiable blind quantum computation using color […]

Long-duration Gamma-ray Burst and Associated Kilonova Emission from Fast-spinning Black Hole–Neutron Star Mergers

Posted by klaurent July 21, 2022Peking

Kavli Affiliate: Zhuo Li | First 5 Authors: Jin-Ping Zhu, Xiangyu Ivy Wang, Hui Sun, Yuan-Pei Yang, Zhuo Li | Summary: Here we collect three unique bursts, GRBs,060614, 211211A and 211227A, all characterized by a long-duration main emission (ME) phase and a rebrightening extended emission (EE) phase, to study their observed properties and the potential […]

Spotting Temporally Precise, Fine-Grained Events in Video

Posted by klaurent July 20, 2022August 1, 2022UCSB

Kavli Affiliate: Matthew Fisher | First 5 Authors: James Hong, Haotian Zhang, Michaël Gharbi, Matthew Fisher, Kayvon Fatahalian | Summary: We introduce the task of spotting temporally precise, fine-grained events in video (detecting the precise moment in time events occur). Precise spotting requires models to reason globally about the full-time scale of actions and locally […]
