摘要:
A bank of input/output buffers are configured such that each input buffer in the bank may select from a plurality of voltage references during single-ended operation. Similarly, the pad associated with each input buffer may serve to supply one of the voltage references for other input buffers within the bank.

An electronic circuit with programmable terminations includes a circuit block, signal pads coupled to the circuit block, programmable termination circuits each associated with a corresponding one of the signal pads, and a reference circuit operative to generate one or more control signals for application to the programmable termination circuits. A given one of the programmable termination circuits is configurable independently of at least one of the other programmable termination circuits into one of a plurality of termination states. Preferably, the programmable termination circuits are each independently configurable to provide a particular termination resistance and a particular supply terminal connection type for the associated signal pad. The invention is particularly well suited for use in integrated circuit applications, such as, for example, those involving FPGAs, FPSCs and ASICs.
摘要:
Telomerase reverse transcriptase is part of the telomerase complex responsible for maintaining telomere length and increasing the replicative capacity of progenitor cells. Telomerase activity is turned off in mature differentiated cells, but is turned back on again in hyperplastic diseases, including many cancers. This disclosure provides regulatory elements that promote transcription in cells that express telomerase reverse transcriptase (TERT). The disclosure also provides systems using TERT promoter sequences for identifying compounds that can be used to modulate telomerase expression

A fringed splash guard used to decoratively protect a vehicle against materials which may be thrown from a vehicles tire. A fringed splash guard can be used on vehicles such as tractor tralers trucks, pick up trucks, vans, cars, and motorcycles. Also provided is a fringed trim and used on a vehicle as a decoration. This fringed trim can also be used as a small splash guard and used to accommodate small vehicles such as motorcycles, a cart, trailers, all terrain, and bicycles.

A joining arrangement is provided for use in the construction of stud frame which includes a releasable attachment/detachment feature. The first member (plate) includes in at least one side wall a formation which, when members are joined, engages a corresponding formation in at least one wall of the second member (stud). The formation, such as a V-shaped protrusion, is/are disposed at an angle to the longitudinal axis of the member and the formation on the second member is disposed generally parallel to its longitudinal axis such that upon engagement of the first and second members, the respective formations in the first and second members engage such that they are in alignment, thereby, securing the first member to the second. Additionally, a plurality of protrusions, which provide a gripping feature, may be formed on the upper surface of web for inhibiting the stud from sliding, slipping, moving and/or migrating within the plate.

The present invention is directed to methods, assays and compositions for implementing such methods and assays for assessing efficacy of individual components in multi-component vaccines and for assessing efficacy of a vaccine against a pathogen. In one aspect, the method of assessing efficacy of a vaccine against a pathogen is a quick assay that tests for an activity correlated with efficacy such as binding in an ELISA rather than requiring the time and expense of an assay that detects actual bactericidal activity. In another aspect, the method for testing the efficacy of an individual component in a multi-component vaccine includes obtaining an immune sample from a subject inoculated with the multi-component vaccine; blocking the portion of the immune sample that recognizes the individual component such as by addition of the individual component, and testing the efficacy of the immune sample to respond to the pathogen.
摘要:
A method for forming a joining profile in a structural member comprises providing an assembly having a base member, a forming body and a pair of side anvils having profiles formed therewithin. The method further comprises mounting the structural member on the base member, advancing the forming body toward the structural member such that the structural member is clamped to the base member, urging the side anvils toward flanges of the structural member, forming a profile in each of the flanges, and engaging protrusions of the side anvils with the web such that opposing portions of the web are forced upwardly by the protrusions at locations adjacent to each one of the flange profiles in order to accommodate formation of the flange profiles in the structural member. Formation of the joining profiles in the structural members allows for detachable engagement thereof with another member having a corresponding mating profile.
摘要:
Recombinant production of immunogenic West Nile Virus (WNV) proteins is described. These proteins, heterodimers comprising the proteins, fusions thereof, polynucleotides encoding the proteins, and combinations thereof, as well as antibodies produced therefrom, can be used in immunogenic compositions for preventing, treating and diagnosing WNV infection. Also described are highly sensitive ELISA and strip immunoassay methods for detecting the presence of WNV in biological samples.
