Enforcing strong stability of explicit Runge--Kutta methods with superviscosity
Zheng Sun, Chi-Wang Shu
A time discretization method is called strongly stable, if the norm of its numerical solution is nonincreasing. It is known that, even for linear semi-negative problems, many expli…
Reply to "Absence of Evidence for the Ultimate Regime in Two-Dimensional Rayleigh-Bénard Convection"
Xiaojue Zhu, Varghese Mathai, Richard J. A. M. Stevens +2
Rely to the comment by Doering et al. in Phys. Rev. Lett. 123, 259401 (2019)
First Season MWA Phase II EoR Power Spectrum Results at Redshift 7
W. Li, J. C. Pober, N. Barry +44
The compact configuration of Phase II of the Murchison Widefield Array (MWA) consists of both a redundant subarray and pseudo-random baselines, offering unique opportunities to per…
Finding the Mode of a Kernel Density Estimate
Jasper C. H. Lee, Jerry Li, Christopher Musco +2
Given points in , how do we find a point which maximizes ? In other words, how do we find the maxim…
Stability of stochastic finite-size spiking-neuron networks: Comparing mean-field, 1-loop correction and quasi-renewal approximations
Dmitrii Todorov, Wilson Truccolo
We examine the stability and qualitative dynamics of stochastic neuronal networks specified as multivariate nonlinear Hawkes processes and related point-process generalized linear…
Individual predictions matter: Assessing the effect of data ordering in training fine-tuned CNNs for medical imaging
John R. Zech, Jessica Zosa Forde, Michael L. Littman
We reproduced the results of CheXNet with fixed hyperparameters and 50 different random seeds to identify 14 finding in chest radiographs (x-rays). Because CheXNet fine-tunes a pre…
