Abstract: Pre-Charge Static Logic (PCSL), is an asynchronous-logic Quasi-Delay-Insensitive architecture based on Static-Logic, featuring fully-range Dynamic Voltage Scaling including robust operation in the sub-threshold voltage regime, with simultaneous low hardware overheads, high-speed and yet low power dissipation. The invented PCSL logic circuit achieves this by integration of the Request sub-circuit into the Static-Logic cell. During the initial phase, the output of Static-Logic cell (within the PCSL logic circuit) is pre-charged. During the evaluate phase, the Static-Logic cell computes the input and the PCSL logic circuit outputs the computation.

Abstract: A modified natural rubber particle having carbon-carbon double bands assigned to multifunctional vinyl monomers graft-copolymerized onto the surface of the modified natural rubber particle, which is prepared by graft-copolymerization of multifunctional vinyl monomers having two or more carbon-carbon double bonds onto natural rubber particles or deproteinized natural rubber particles. One of the methods for producing a modified natural rubber particle includes the steps of: forming inclusion complex of the multifunctional vinyl monomers having two or more carbon-carbon double bonds with a guest-protecting agent to protect at least one of the double bonds of the multifunctional vinyl monomers; graft-copolymerizing the resulting inclusion complex onto natural rubber particles or deproteinized natural rubber particles; and deprotecting the protected double bonds by removing the guest-protecting agent from the obtained graft-copolymer.

Abstract: A novel group of gastrokines called Gastric Antrum Mucosal Protein is characterized. A member of the group is designated AMP-18. AMP-18 genomic DNA, cDNA and the AMP-18 protein are sequenced for human, mouse and pig. The AMP-18 protein and active peptides derived from it are cellular growth factors. Surprisingly, peptides capable of inhibiting the effects of the complete protein, are also derived from the AMP-18 protein. Cytoprotection and control of mammalian gastro-intestinal tissue growth and repair (restitution) is facilitated by the use of the proteins, making the proteins candidates for therapies in inflammatory bowel disease and gastric ulcers.

Abstract: Artificial control of a prosthetic device is provided. A brain machine interface contains a mapping of neural signals and corresponding intention estimating kinematics (e.g. positions and velocities) of a limb trajectory. The prosthetic device is controlled by the brain machine interface. During the control of the prosthetic device, a modified brain machine interface is developed by modifying the vectors of the velocities defined in the brain machine interface. The modified brain machine interface includes a new mapping of the neural signals and the intention estimating kinematics that can now be used to control the prosthetic device using recorded neural brain signals from a user of the prosthetic device. In one example, the intention estimating kinematics of the original and modified brain machine interface includes a Kalman filter modeling velocities as intentions and positions as feedback.

Abstract: A communication method of coordinated multi-point transmission systems. Based on the Zadoff-Chu sequences, multiple training sequences are implemented, and the training sequences are a set of robust orthogonal training sequence (ROTS). Preamble signals that use the set of training sequences can be transmitted from multiple base stations/relay stations at the same time. In the case with the mixture signal of multiple preamble signals, user equipment can still use the received signal to estimate multiple carrier frequency offsets of the corresponding base stations/relay stations.
