摘要:
A soluble receptor to IL-20 having two polypeptide subunits, IL-20RA (formerly called ZcytoR7) and IL-20RB (formerly called DIRS1). The two subunits are preferably linked together. In one embodiment one subunit is fused to the constant region of the light chain of an immunoglobulin, and the other subunit is fused to the constant region of the heavy chain of the immunoglobulin. The light chain and the heavy chain are connected via a disulfide bond.

A gearbox is placed between two clock domains to allow data to be transferred from one domain to the other. Although the two domains may operate at the same clock frequency, typically one domain has a faster clock speed than the other. The gearbox is disposed between the two clock domains to control timing of data transfer from one to the other, by selecting a pattern which identifies when data is made transparent for the transfer. The gearbox allows a number of clock ratios to be selected, so that a particular clock ratio between the two domains may be readily selected in the gearbox for the data transfer.

A spatial light modulator for use in projection display applications is provided. The spatial light modulator includes a substrate including a plurality of electrically active circuits and an electrode layer electrically coupled to at least one of the plurality of electrically active circuits. In one embodiment, the electrode layer includes a semi-continuous layer with at least one optical path. The spatial light modulator also includes a shielding layer electrically isolated from the electrode layer and disposed between the substrate and the plurality of electrically active circuits and an electrical connector coupling the shielding layer to a reference potential. In a specific embodiment, the shielding layer of the spatial light modulator converts incident light energy to electrical current and routes the current back to a source. In another specific embodiment, the shielding layer converts electrical field disturbance to electrical current and routes the current back to a source.

A first-in, first-out (FIFO) unit switches between strobe sources. The FIFO uses a multiplexer to switch between two or more strobes so that different data strobes may be used with the FIFO to strobe in the data. In one implementation, the FIFO uses four data latches to strobe in data bits and output a pair of data bits onto the internal bus each half clock cycle.

A node comprises at least one agent and an input/output (I/O) circuit coupled to an interconnect within the node. The I/O circuit is configured to communicate on a global interconnect to which one or more other nodes are coupled during use. Addresses transmitted on the interconnect are in a first local address space of the node, and addresses transmitted on the global interconnect are in a global address space. The first local address space includes at least a first region used to address at least a first resource of the node. The node is programmable, during use, to relocate the first region within the first local address space, whereby a same numerical value in the first local address space and a second local address space corresponding to one of the other nodes coupled to the global interconnect refers to the first resource in the node during use.

In a computer memory system, memory access operations are significantly enhanced by employing a data path between the read only memory (ROM) and the system processor that is separate and independent from the data path or paths between the system processor and the random access memory (i.e., RAM or DRAM). The separate ROM data path includes a full cache line buffer which stores the ROM data until the system data bus is available to transport the ROM data. With a separate ROM data path, that includes a full cache line buffer, memory access operations are more efficiently conducted because a RAM access (i.e., a read or write operation) and a ROM access (i.e., a read operation) can be executed concurrently.

A bus bridge circuit employs a dynamic allocation scheme that allows read transactions to be pipelined without deadlock and without the need for permanently reserving multiple buffer slots for read response transactions. The bus bridge circuit associates input and output buffers with a node and includes a state machine to monitor the number and type of transaction packets currently in slots that make up the buffers. In particular, the state machine monitors the number of transaction packets loaded in the output buffer slots, the number of outstanding read transactions for the node, and the number of read response transactions currently loaded in the output buffer. The state machine then allows the node to load a READ or WRITE transaction only if the monitored data indicates at least one of the buffer slots will be available to service a READ RESPONSE subsequently loaded by the node. The state machine launches READs to the node only when an unallocated buffer slot is available to service the corresponding READ RESPONSE.

Proteins having substantially the same biological activity as PDGF are provided. In one aspect, a protein homodimer having two polypeptide chains is disclosed, each of the chains being a mosaic of amino acid sequences substantially identical to portions of the A- and B-chains of PDGF, the protein being chemotactic or mitogenic for fibroblasts. Therapeutic compositions comprising such proteins in combination with a physiologically acceptable carrier or diluent are also provided. Such therapeutic compositions may be used within methods for enhancing the wound-healing process in warm-blooded animals.
