Abstract: Disclosed is a phase-shifted square wave modulation technique for single-phase and three-phase IM2DC applications in HVDC/MVDC systems. A square wave based modulation waveform is applied to each cell of IM2DC and compared to the phase-shifted carrier waveforms to generate device gate signals. As a result, a higher equivalent switching frequency can be achieved, and square wave based arm and AC link waveforms will be generated. In addition, power flow of IM2DC can be controlled by a phase shift angle of the square modulation waveforms between HVS and LVS. The converter cell capacitors can be reduced in size because they are only required to smooth high switching frequency ripple components. In addition, lower TDR can be achieved due to the higher power transferring capability of square waves.

Abstract: The present invention provides a new therapeutic method for modeling neuronal responses. Human induced pluripotent stem cells (hiPSCs) emerge recently as alternative sources of primary brain cells to establish Alzheimer's disease (AD) models in vitro. While previous investigations demonstrate the potential of hiPSCs in modeling AD, the 2-D cultures used in these studies cannot fully recapitulate AD-associated neuropathology. 3-D cortical spheroids (forebrain-like structure) were derived from human induced pluripotent stem cells in a bioreactor culture, which can be used to recapitulate AD-associated neuropathology, to screen the therapeutic drugs and to predict neurotoxicity.
