  • Patent number: 10373661
    Abstract: A stacked semiconductor device includes a plurality of semiconductor dies stacked in a vertical direction, first and second signal paths, a transmission unit and a reception unit. The first and second signal paths electrically connect the plurality of semiconductor dies, where each of the first signal path and the second signal path includes at least one through-substrate via. The transmission unit generates a first driving signal and a second driving signal in synchronization with transitioning timing of a transmission signal to output the first driving signal to the first signal path and output the second driving signal to the second signal path. The reception unit receives a first attenuated signal corresponding to the first driving signal from the first signal path and receives a second attenuated signal corresponding to the second driving signal from the second signal path to generate a reception signal corresponding to the transmission signal.

  • Publication number: 20180170966
    Abstract: The peptide of the present invention performs a function, which is the same as or similar to that of natural interleukin (IL)-3, and has superior skin permeability due to the small size thereof. In addition, the peptide of the present invention suppresses the activation of NF-?B and nuclear transition by inhibiting the receptor activator of nuclear factor kappa-B ligand (RANKL)-RANK signaling pathway, and suppresses the expression of a RANKL or an inflammatory cytokine-induced tartrate-resistant acid phosphatase (TRAP), cathepsin K, or TNF receptor type 1 or type 2, thereby inhibiting osteoclast differentiation depending on the treatment concentration. Moreover, the peptide of the present invention can contribute to osteoblast differentiation by promoting the expression of osteoblast differentiation markers such as osteocalcin (OCN), osteoprotegerin (OPG), bone sialoprotein (BSP), or osteopontin (OPN).
