1. IntroductionDue to the diverse topography and geomorphology of China, mountains are particularly dominant, especially in the southern region. As a result, many transmission pylons are constructed on slopes, known as transmission pylons on side slopes. Transmission tower slopes are common geological environments in power transmission lines, and landslides often pose significant risks to transmission line safety, severely impacting their operation [1].

We show that a positive feedback loop between sodium current inactivation and wave-front ramp-up speed causes a saddle-node bifurcation to result in bistable planar and spiral waves in electrically excitable media, in which both slow and fast waves are triggered by different stimulation protocols. Moreover, the two types of spiral wave conduction may interact to give rise to more complex spiral wave dynamics.

Asymmetric fluorene-based fused-ring molecules acceptors (BTOFIC and BTFIC) were synthesized. BTOFIC and BTFIC were easily soluble in common organic solvents. The highest occupied molecular orbital energy levels (EHOMOs), the lowest unoccupied molecular orbital energy levels (ELUMOs) and the band gaps (Egs) of BTOFIC and BTFIC were -5.91, -3.87 and 2.04 eV, -5.72, -3.81 and 1.91 eV, respectively.
