Double-cropping rice in South China continues to break the total yield record, but the yield potential of single-cropping rice is not being realized.Radiation use efficiency (RUE) has been singled out as an important determinant of grain yield in many cereal species.However, there is no information on whether the yield gaps in double-cropping rice
Symmetry is an important property found in a large number of nonlinear systems.The study of chaotic systems with symmetry is well documented.However, the literature is unfortunately very poor concerning the dynamics of such systems when their symmetry is altered or broken.In this paper, we investigate the dynamics of a simple jerk system with hyper
The main obstacle for the further development and commercialization of solid-state DC circuit breakers is the high ON-state power losses caused by the active power semiconductor devices.This paper presents an experimental evaluation of the electrical ON-state performance among several commercial high-power semiconductor device technologies rated at
