Can nonpartisan primaries boost turnout and lessen demographic disparities? [PDF]
PLoS ONEU.S. congressional general elections are largely uncompetitive, featuring candidates who emerge from low-turnout primaries. Voters in these primaries are unrepresentative of the broader electorate; primary voters tend to be older and wealthier.

Research on wear and grinding models of high-speed turnouts based on semi-Hertz contact [PDF]
Scientific ReportsIn order to reduce turnout rail wear, the paper establishes a coupled dynamics model and a turnout rail wear model that consider the true profile of the turnout rail, the vehicle’s continuous traction force while passing, and the operational resistance ...

Simulation of Train-Turnout Coupled Dynamics Using a Multibody Simulation Software
Modelling and Simulation in Engineering, 2018 With the advancements of computing power, multibody simulation (MBS) tool is used to study not only train dynamics but also more realistic phenomena such as train-track coupled dynamics. However, train-turnout coupled dynamics within MBS is still hard to
