Role of Ascertainment Bias in Determining Case Fatality Rate of COVID-19

open access: yesJournal of Epidemiology and Global Health, 2021
Case fatality rate (CFR) is used to calculate mortality burden of COVID-19 under different scenarios, thus informing risk-benefit balance of interventions both pharmaceutical and nonpharmaceutical.

Fast and Accurate Coarsening Simulation with an Unconditionally Stable Time Step

open access: yes, 2003
We present Cahn-Hilliard and Allen-Cahn numerical integration algorithms that are unconditionally stable and so provide significantly faster accuracy-controlled simulation.

L'CO/LFIR Relations with CO Rotational Ladders of Galaxies Across the Herschel SPIRE Archive

open access: yes, 2016
We present a catalog of all CO (J=4-3 through J=13-12)), [CI], [NII] lines available from extragalactic spectra from the Herschel SPIRE Fourier Transform Spectrometer (FTS) archive combined with observations of the low-J CO lines from the literature and ...

Multilevel analysis of dendroclimatic series with the R-package BIOdry.

open access: yesPLoS ONE, 2018
The R-package BIOdry allows to model and compare fluctuations of Tree-ring Width (TRW) and climate, or dendroclimatic fluctuations, while accounting for source variability.

Data augmentation in Rician noise model and Bayesian Diffusion Tensor Imaging [PDF]

open access: yes, 2014
Mapping white matter tracts is an essential step towards understanding brain function. Diffusion Magnetic Resonance Imaging (dMRI) is the only noninvasive technique which can detect in vivo anisotropies in the 3-dimensional diffusion of water molecules ...

Data Cube Approximation and Mining using Probabilistic Modeling [PDF]

open access: yes, 2007
On-line Analytical Processing (OLAP) techniques commonly used in data warehouses allow the exploration of data cubes according to different analysis axes (dimensions) and under different abstraction levels in a dimension hierarchy.

Asymptotically Optimal Approximation Algorithms for Coflow Scheduling

open access: yes, 2018
Many modern datacenter applications involve large-scale computations composed of multiple data flows that need to be completed over a shared set of distributed resources. Such a computation completes when all of its flows complete.

flexsurv: A Platform for Parametric Survival Modeling in R

open access: yesJournal of Statistical Software, 2016
flexsurv is an R package for fully-parametric modeling of survival data. Any parametric time-to-event distribution may be fitted if the user supplies a probability density or hazard function, and ideally also their cumulative versions.
