The Carrier Phase Shifted (CPS) strategy is conventional for cascaded multilevel inverter, because it can naturally ensure all cascaded cells to output balanced power. However, in point of spectra of the output line voltage, CPS is suboptimal to Phase Disposition (PD) strategy, because the latter can not naturally ensure power balance. This paper presents an improved PD strategy, inspiration from the disposition of CPS strategy triangle carriers. Just reconstructing the triangle carriers of PD strategy, it can not only reserve the waveform quality of the line voltage to be optimal, but also naturally ensure the output power of each cascaded cells to be balanced.

According to the body-specificity hypothesis, people with different kinds of bodies should think differently. Since this hypothesis was proposed, a growing body of experimental evidences support it. However, the types of physical or empirical characteristics involved at present are relatively limited, and handedness is the main one, while other bodily traits are seldom studied. In addition, most of the current studies have only found the correlation between physical characteristics and cognition, while the causal relationship between them has not been extensively and deeply studied. This article reviews the major studies that have shown body-specificity effects on different bodily traits and make some recommendation for further research.
