The role of complementary products on platform adoption : Evidence from the video console market

This paper studies the importance of the interdependences within platform-based markets. Specifically, the work examines the influence of complementary product portfolios on the adoption of platforms by individuals. The study analyzes data from a panel of 17 video game platforms in three regions (the US, Japan and Europe) for the period between 1989 and 2011. The results suggest that platform adop

The prevalence and determinants of anti-DFS70 autoantibodies in an international inception cohort of systemic lupus erythematosus patients

Autoantibodies to dense fine speckles 70 (DFS70) are purported to rule out the diagnosis of SLE when they occur in the absence of other SLE-related autoantibodies. This study is the first to report the prevalence of anti-DFS70 in an early, multinational inception SLE cohort and examine demographic, clinical, and autoantibody associations. Patients were enrolled in the Systemic Lupus International

Robust Phase-Based Positioning Using Massive MIMO with Limited Bandwidth

This paper presents a robust phase-based positioningframework using a massive multiple-input multiple-output(MIMO) system. The phase-based distance estimates of MPCstogether with other parameters are tracked with an ExtendedKalman Filter (EKF), the state dimension of which varies withthe birth-death processes of paths. The iterative maximumlikelihoodestimation algorithm (RIMAX) and the modeling of
