  • Publication number: 20250090720
    Abstract: The present invention relates to a tubular scaffold and a method of manufacturing the same. The tubular scaffold has physical properties matching the characteristics of a tubular organ that bends or rotates when a double layer is formed by electrospinning nanofibers, and not only has excellent cell adhesion ability but may also maintain cell functions. Also, since such effects have been proven in an animal model, the tubular scaffold may be mass-produced and used as a highly functional tubular organ having various sizes and lengths.

  • Patent number: 12243609
    Abstract: An octo mode program and erase operation method to reduce test time in a non-volatile memory device. M/8 word lines corresponding to an octo row, among M word lines, are simultaneously selected, and a write voltage is applied to memory cells connected to M/8 word lines corresponding to the octo row. A voltage that is different from the write voltage is applied to memory cells connected to the rest of word lines, except for M/8 word lines corresponding to the octo row, when the octo signal is applied to an address decoder.
