Abstract: A linker for a unimolecular FRET biosensor based on a principle of fluorescence resonance energy transfer, the linker including: a polypeptide containing 52 to 400 amino acids residues, wherein at least 45% of a total number of the amino acid residues are glycine, alanine, or both thereof, and at least 10% of the total number of the amino acid residues are alanine.

Abstract: A file management apparatus includes a file storage portion and a manipulation portion. The file storage portion stores a plurality of files therein. Each file includes one or more data structures. Each data structure includes one or more elements. The file storage portion further identifies each file with a file identifier and identifies each data structure within the file with an internal identifier and with the number of data structures contained in the file. The position of each data element and the number of data elements within a data structure are also identified. The manipulation portion manipulates the structure of the data stored in the file storage portion by employing the file identifier, the data structure identifier, and element position.

Abstract: A program developing system includes a plurality of graphic editors representing specification definition information a user inputs in representation formats different from each other and a mutual conversion unit for converting specification definition which the user described with a graphic editor into a representation format of another graphic editor. The mutual conversion unit activates another graphic editor to allow input of specification definition by the converted representation format. The graphic editors can hierarchically represent specifications and allows specification description at an arbitrary level.

Abstract: A data-driven type computer system including an input limiting section for monitoring a current number of packets existing in the circular pipeline of the system while being processed. The input limiting section is adapted to control packets from being inputted from the external unit when the current number of packets exceeds a specified threshold value which is greater than a minimum packet number existing in the circular pipeline and which allows the attainment of the highest possible throughput of the system. The input limiting section further includes a predictive control unit to preliminarily analyze a current data flow graph to be processed in the system and also to take order in rank a possible rate of increase in the quantity of packets generated by a copying operation as well as a possible rate of reduction in the prior processing by the system.

Abstract: In a data driven type information processing apparatus, an operation processing unit. The operation processing unit executes processing of a high function instruction on the basis of corresponding information stored in a specification data memory, and branches data packets, received from a pair data detecting unit, to a simple instruction processing unit. The apparatus further includes a junction unit for joining data packets outputted from the high function and the simple function instruction processing units to output them to an output unit.

Abstract: A system for actualizing a process of a multi-generation packet by managing the generations of the packet inputted in a firing process module of a data driven type processor. The firing process module includes a generation management unit for rearranging the disk order of a sequence relationship associated with a periodic circulation of the generation numbers of a packet inputted. Further included is a subsystem for separating an address space in hashing when obtaining an address of a queuing memory of the firing process module.

Abstract: An apparatus for manipulating a relational data base includes a unit for describing input data in a table format, a unit for describing all the operational manipulation with respect to the input data in a non-text format, and a unit for outputting data by referring to the relational data base based on the described input data and operational manipulation. The input data of a table format includes an input table and an output table. The input table includes an operational description region and the output table includes a region wherein a map relation between the respective items of the input and output table is described. The manipulation contents are described in the operation manipulation description region and the map relation description region. The operation flow is described and defined by a connection line with directiveness.
