Abstract: The present invention provides a hydrogel platform using, as a substrate, hyaluronic acid (HA) conjugated to a pyrogallol (PG) moiety. The HA-PG conjugate of the present invention can be rapidly crosslinked by two different methods, in each of which an oxidizing agent is used or a pH is adjusted. The hydrogel of the present invention can not only have excellent biocompatibility, but also can have efficiently controlled physical characteristics such as a crosslinking rate, elasticity, and adhesive strength, depending on each crosslinking method. On the basis of such excellent stability and functionality, the hydrogel of the present invention can be used in various fields including drug delivery, biopharmaceutical materials such as a wound healing agent or anti-adhesive agent, medicines, and cosmetic products.

Abstract: In described embodiments, a multiple first-in, first-out buffer pointers (multi-FIFO pointers) alignment system includes synchronization circuitry to align multiple FIFO buffer operations. A FIFO read clock stoppage signal is generated by master logic that stops the read clock shared by all the transmit channels and then re-starts the read clock to align them. The FIFO read clock stoppage signal is applied to the read clock of all FIFOs which need to be aligned and, when rate change is needed, the FIFO read clock stoppage signal suspends the read clock, causing local write and read pointers to be reset. After the FIFO read clock stoppage signal is de-asserted, the read clock starts to all FIFOs concurrently, thereby aligning the channels.

Abstract: A latch circuit having reduced propagation delay and set-up and hold times comprises at least one set of cross-coupled transistor devices arranged between an upper supply terminal of the circuit and a lower supply terminal of the circuit. A first input transistor device is coupled in parallel with a first one of the transistor devices of the set of cross-coupled transistor devices, and a second input transistor device is coupled in parallel with a second one of the transistor devices of the set of cross-coupled transistor devices. The first and second input transistor devices are adapted for application of respective uncomplemented and complemented inputs thereto during an initialization mode of the latch circuit. Uncomplemented and complemented output signals are generated at corresponding output terminals associated with the set of cross-coupled transistor devices during an evaluation mode of the latch circuit.
