The blind watermark extraction algorithms based on discrete cosine transform need some the priori knowledge. To overcome this problem, in this paper, two kinds of blind extraction algorithms using wavelet transform are presented with out prior knowledge. Firstly, this paper proposed an extraction algorithm based on discrete wavelet transform. The low(More)
Human-induced pluripotent stem cells (hiPSCs) have great potential for future use in therapeutic regenerative medicine. Based on the current protocol for deriving hiPSCs, invasive procedures such as skin biopsies and venipuncture are required for obtaining donor samples. Herein, we present a detailed protocol for deriving hiPSCs from human finger-prick (FP)(More)
In vitro generation of red blood cells (RBCs) from human embryonic stem cells and human induced pluripotent stem cells appears to be a promising alternate approach to circumvent shortages in donor-derived blood supplies for clinical applications. Conventional methods for hematopoietic differentiation of human pluripotent stem cells (hPSC) rely on embryoid(More)
