We present a self-consistent model for explosive financial bubbles, which combines a mean-reverting volatility process and a stochastic conditional return which reflects nonlinear positive feedbacks and continuous updates of the investors' beliefs and sentiments. The conditional expected returns...

Aiming at the issues and defects triggered by the single power form of a traditional electric vehicle, a planetary gear-based master-slave electrohydraulic power-coupled electric vehicle (MS-EHPCV) was proposed. MS-EHPCV can decrease the peak torque during the frequent start-stop process and...

Abstract ; Nickel oxide (NiO x ) is one of the most promising inorganic hole transport layers for perovskite solar cells (PSCs), due to its low cost, high hole mobility, and superior stability. However, the mismatched energy level and undesirable chemical reaction at the NiO x /perovskite...
