Abstract:
Polypeptides comprising all or part of a variant integrin α subunit A domain and its flanking region are described. In solution or in membrane-associated form, the A domain polypeptides of the invention exists predominantly in a high affinity conformation. In the polypeptides of the invention, referred to as variant integrin polypeptides, a crucial isoleucine or glutamic acid residue is altered. For example, the glutamic acid can be either deleted or replaced with different amino acids residue, e.g., glutamine, aspartic acid, or alanine The variant integrin polypeptides of the invention selectively impair binding of activation-dependent ligands, but not independent ligands. They are useful in screening assays for the identification of molecules that enhance binding of variant polypeptides with impaired binding. In addition, they are useful in distinguishing between activation-dependent ligands and activation-independent ligands. They are also useful for generating antibodies, e.g., monoclonal antibodies, which bind to the impaired form of an integrin. Some such antibodies recognize an epitope that is either not present or not accessible on an integrin that is in the high affinity conformation. The variant integrin polypeptides of the invention can be derived from any integrin α subunit that could be used therapeutically.

Abstract:
The invention discloses a mechanical performance testing device and a hydraulic control system thereof. The instrument comprises a base, a fixing means, a first testing means and a second testing means. Wherein the base is connected with the fixing means, each of the first testing means and the second testing means is configured to cause the fixing means to move in various directions. And the instrument can simultaneously apply multiple forces and torques on the element, such that the different stiffness characteristics of the element can be tested simultaneously. The hydraulic control system comprises fuel tank, oil pump and control valves. And the fuel tank, the oil pump and the control valves connect successively. The mechanical performance testing device with hydraulic control system can improve efficiency of the test, reduce the working intensity of inspector, increase the security in detection process, and improve the accuracy of measurement results.
Abstract:
It is provided a dedicated winding tester for composite wire rod-type specimens for effectively measuring the minimum winding radius of the wire rod-type specimens being made with carbon fiber or glass fiber reinforced composites in various diameters or textures via automatically gripping specimens, tightly winding, and sequentially proceeding sustained load in time, thereby supplying test data and design consideration in actual use and transport of the wire rod-type specimens being made of carbon fiber or glass fiber reinforced composites that comprises a shield, a specimen receiver and a winding device being arranged within said shield, as well as a programmable controller being arranged outside the shield.
Abstract:
Techniques for categorizing item listings based on parsing item listing titles are described. According to various embodiments, listing titles of one or more item listings on a marketplace website are accessed, the item listings being associated with a particular product category in a product category structure of the marketplace website. Words in each of the listing titles may then be converted to semantic tokens in a token symbol space, based on a tokenization process. Thereafter, n-gram modeling may be performed on the tokens corresponding to each of the listing titles of the item listings in the particular product category. One or more dominant n-gram models associated with the listing titles of the item listings in the particular product category may then be identified.
Abstract:
The present invention provides a system and method of managing traffic traversing an intermediary based on a result of end point auditing. An authentication virtual server of an intermediary may determine a result of an end point analysis scan of a client. Responsive to the determination, the traffic management virtual server can obtain the result from the authentication virtual server. Further, the traffic management virtual server may apply the result in one or more traffic management policies to manage network traffic of a connection of the client traversing the intermediary. In some embodiments, the authentication virtual server may receive one or more expressions evaluated by the client. The one or more expressions identifies one or more attributes of the client. The traffic management virtual server can also determine a type of compression or encryption for the connection based on applying the one or more traffic management policies using the result.
