We propose moving average threshold heterogeneous autoregressive (MAT-HAR) models as a novel combination of heterogeneous autoregression (HAR) and threshold autoregression (TAR). The MAT-HAR has multiple groups of lags of a target series, and a threshold term can appear in each group. The...

Continued use of retracted articles amplifies the adverse consequences of propagating questionable knowledge. Because traditional approaches have not been adequate in alleviating continued use of retracted articles, scholars have called for the use of social media to aid in disseminating...

The high temperature deformation behavior of a X30CrMoN15-1 high-nitrogen stainless steel (HNSS) has been investigated using uniaxial compression test in the temperature range of 850–1250 °C and strain rate of 0.001–10 [[EQUATION]] . An Arrhenius-based hyperbolic sine equation was used to...

This paper studies the problem of information design in a general security game setting in which multiple self-interested defenders attempt to provide protection simultaneously for the same set of important targets against an unknown attacker. A principal, who can be one of the defenders, has...
