Multiple Self‐Controlled Case Series for Large‐Scale Longitudinal Observational Databases
Shawn E. Simpson,David Madigan,Ivan Zorych,Martijn J. Schuemie,Patrick B. Ryan,Marc A. Suchard +5 more
TL;DR: A regularized multiple SCCS approach that incorporates potentially thousands or more of time‐varying confounders such as other drugs is proposed, which successfully handles the high dimensionality and can provide a sparse solution via an L1 regularizer.

Mechanical responses of the periodontal ligament based on an exponential hyperelastic model: a combined experimental and finite element method
TL;DR: The good agreement between the simulated results and experimental data demonstrates that the V–W model is capable of describing the mechanical behavior of the PDL, and the model and its implementation into FE code are validated.
Journal ArticleDOI
Development and parameter identification of a visco-hyperelastic model for the periodontal ligament.
TL;DR: The present study developed and implemented a new visco-hyperelastic model that is capable of predicting the time-dependent biomechanical behavior of the periodontal ligament and simulated results are in good agreement with the experimental data.

A New Method to Determine Material Parameters from Machining Simulations Using Inverse Identification
TL;DR: In this article, the authors use a parameter identification method to identify Johnson-Cook material parameters from machining simulations, which is able to correctly reproduce the target simulations for different target materials with a small number of FEM simulations.

A modified parallel-sided shear zone model for determining material constitutive law
TL;DR: In this paper, a modified parallel-sided shear zone model at primary zone is presented for determining J-C parameters, based on the assumption of nonequidistant primary zone, the distribution of velocity, strain rate, strain, and temperature is successfully predicted.

Regression with missing X’s: A review
TL;DR: The literature of regression analysis with missing values of the independent variables is reviewed in this article, where six classes of procedures are distinguished: complete case analysis, available case methods, least squares on imputed data, maximum likelihood, Bayesian methods, and multiple imputation.
