BackgroundEpithelioid trophoblastic tumor (ETT) is the rarest gestational trophoblastic tumor, with poor response to chemotherapy. Hysterectomy, as the cornerstone therapy for early ETT, is particularly challenging in reproductive-age women who often

This paper proposes a modeling and transient analysis method for quasi-resonant converter (QRC) based on the equivalent small parameter method (ESPM), with different time scale features being considered. Due to the existence of resonant and filtered

The equivalent small-parameter method (ESP), is usually applied to acquire the analytical solution of a nonlinear system, due to its significant advantages of combining disturbance and harmonic balance methods. When considering the mechanism of the c
