摘要:
Binding can automatically take place between controls and information sources at runtime. This minimizes an amount of code that is to be generated by a user and thus can lower errors from the code. In addition, some wizards that allow binding without code writing can become problematic since some information is not available at runtime (e.g., when the wizard operates prior to runtime.) Relevant information is received and at least one binding is created based off received information.

There is alteration of a late-bound expression produced by a compiler into an early-bound structure. Alteration of the late-bound expression can occur at runtime and a visitor pattern can be used to create the alteration. In one instance, a conversion from late-bound to early-bound takes place through replacing a late-bound property with a statically typed call. The early-bound structure can translate into an expression tree to enable an implementation of a store specific query operated upon storage.

Programmers typically like operating with databases through use of classes. Classes allow a user to function with a database through use of a non-database programming language. To ease use of the classes, a class context is generated at runtime that does not force a programmer to handle various source files that are a product of class generation. Therefore, the user can have the ease of using classes without having to perform extra actions.

The present invention relates to a system and methodology to facilitated data object persistence. An object schema is utilized to provide metadata for types in addition to what is provided by the type system for an underlying programming language. This metadata is then utilized by the system to translate data to and from user objects during a materialization or persistence process. The object schema provides information external to programming logic and type definitions. Consequently, the object schema can be deployed independent of an application thereby allowing the persistence storage of user objects to change without force the user to recompile and deploy application code.
摘要:
Systems, processes, and devices are provided which are useful for testing blood or plasma donations to detect those specific donations which are contaminated by a virus above a predetermined level. Samples are formed into pools which are subsequently tested for virus contamination by a high-sensitivity test such as PCR. The pools are tested in accordance with an algorithm by which a sample from each donation is mapped to each element of an N-dimensional matrix or grid. Each element of the matrix is identified by a matrix identifier, Xrcs, where rcs defines the dimensional index. An aliquot is taken from each sample, and subpools are formed, each subpool comprising aliquots of samples in which one dimensional index is fixed. All of the subpools are tested in one PCR test cycle. The dimensional indicia of each positive subpool is evaluated mathematically in accordance with a reduction by the method of minors, thereby unambiguously identifying a unique element in the grid, thereby unambiguously identifying a uniquely positive blood or plasma donation.
摘要:
A process is provided for preparing samples of blood, blood plasma, blood serum, or plasma proteins, including blood factor products, for PCR testing which minimizes contaminants which may interfere with the analysis. The process includes centrifugation of the initial sample to form a sample pellet, removing at least a portion of the supernatant from the pellet, and washing the pellet with an aqueous buffer. The buffer and washed pellet are then centrifuged, and a portion of the remaining supernatant is removed along with any contaminants contained therein. The clean, substantially contaminant-free pellet is then processed for PCR analysis.
摘要:
A method is provided for identifying viral positive biological fluid donations in the fewest number of test cycles. The method comprises providing biological fluid donations and defining an n-dimensional matrix comprising a multiplicity of elements, each element being identified by a matrix notation comprising an index for each dimension of the array. Samples are taken from each fluid donation and mapped to a matrix element with each sample identified by its corresponding element's notation; n aliquots being taken from each sample and subpools formed from the aliquots with each subpool containing an aliquot from all samples mapped to elements in which one of the dimensional indices is fixed. Subpools are tested for viral indication and the dimensional index of each subpool that returns a positive viral indication is determined. The dimensional indices are combined to identify a subset of matrix elements that contain a viral positive sample.
摘要:
A data mapping architecture for mapping between two or more data sources without modifying the metadata or structure of the data sources themselves. Data mapping also supports updates. The architecture also supports at least the case where data sources that are being mapped, are given, their schemas predefined, and cannot be changed. The architecture includes a mapping component that receives respective metadata from at least two arbitrary data models, and maps expressions between the data models.
摘要:
Systems, processes, and devices are provided which are useful for testing blood or plasma donations to detect those specific donations which are contaminated by a virus above a predetermined level. An apparatus and process is described which forms individual, separately sealed and connected sample containers from a flexible hollow tubing segment connected to a fluid donation container. The tubing segment is sealed at spaced-apart intervals along its length, with tubing segment portions in the intervals between the seals defining containers, each of which holds a portion of a plasma sample. The contents of the containers are formed into pools which are subsequently tested for virus contamination by a high-sensitivity test such as PCR. The pools are tested in accordance with an algorithm by which a sample from each donation is mapped to each element of an N-dimensional matrix or grid. Each element of the matrix is identified by a matrix identifier, Xrcs, where rcs defines the dimensional index. An aliquot is taken from each sample, and subpools are formed, each subpool comprising aliquots of samples in which one dimensional index is fixed. All of the subpools are tested in one PCR test cycle. The dimensional indicia of each positive subpool is evaluated mathematically in accordance with a reduction by the method of minors, thereby unambiguously identifying a unique element in the grid, thereby unambiguously identifying a uniquely positive blood or plasma donation.
