Embodiments relate to improving user experiences when executing binary code that has been translated from other binary code. Binary code (instructions) for a source instruction set architecture (ISA) cannot natively execute on a processor that implements a target ISA.

Methods of lowering the error rate of massively parallel DNA sequencing using duplex consensus sequencing
Next Generation DNA sequencing promises to revolutionize clinical medicine and basic research. However, while this technology has the capacity to generate hundreds of billions of nucleotides of DNA sequence in a single experiment, the error rate of approximately 1% results in hundreds of millions of sequencing mistakes. These scattered errors can be tolerated in some applications but become extremely problematic when “deep sequencing” genetically heterogeneous mixtures, such as tumors or mixed microbial populations. To overcome limitations in sequencing accuracy, a method Duplex Consensus Sequencing (DCS) is provided. This approach greatly reduces errors by independently tagging and sequencing each of the two strands of a DNA duplex. As the two strands are complementary, true mutations are found at the same position in both strands. In contrast, PCR or sequencing errors will result in errors in only one strand. This method uniquely capitalizes on the redundant information stored in double-stranded DNA, thus overcoming technical limitations of prior methods utilizing data from only one of the two strands. |

Method for preparing pluripotent stem cells
An object of the present invention is to provide a method capable of inexpensively and conveniently preparing cells having pluripotency and a very low risk of tumorigenic transformation. The cells can be prepared by suspension-culturing mammalian mesenchymal stem cells such as human mesenchymal stem cells from bone marrow (hMSC-BM) and human adipose tissue-derived mesenchymal stem cells (hAT-MSC) (also referred to as “human adipose-derived stem cells [hADSC]”), 7 types of human adherent mature cells (human hepatocyte cells [hHEP cells], human umbilical vein endothelial cells [HUVEC cells], human dermal lymphatic microvascular endothelial cells [HMVEC cells], human epidermal keratinocyte cells [NHEK cells], human bronchial epithelial cells [NHBE cells], human melanocyte cells [NHEM cells], and human smooth muscle cells [UASMC cells]), and 3 types of human adherent precursor cells (human dermal fibroblast cells [NHDF cells], human skeletal muscle myoblast cells [HSMM cells], and human osteoblast cells [NHOst cells]) to form cell masses (spheroids). |
