A method and apparatus are disclosed for improving the processing time of reduced complexity sequence estimation techniques, such as reduced state sequence estimation (RSSE). The possible values for the branch metrics in the RSSE are precomputed to permit pipelining and the shortening of the critical path. The computational load of the precomputations is reduced for multi-dimensional trellis codes by precomputing each dimension of the multi-dimensional trellis code separately. Prefiltering techniques are used to reduce the computational complexity by shortening the channel memory. A hybrid survivor memory architecture is disclosed for RSSE for a channel having a channel memory of length L, where the survivors corresponding to the L past decoding cycles are stored in a register exchange architecture, and survivors corresponding to later decoding cycles are stored in a trace-back architecture (TBA) or register exchange architecture (REA). Symbols are mapped to information bits to reduce the word size before being moved from the first register exchange architecture to the trace-back architecture (TBA) or the second register exchange architecture.

The present invention provides a novel approach for storing, analyzing, and / or accessing biological data in a cloud computing environment. Sequence data generated by a particular sequencing device may be uploaded to the cloud computing environment during a sequencing run, which reduces the on-site storage needs for the sequence data. Analysis of the data may also be performed in the cloud computing environment, and the instructions for such analysis may be set at the originating sequencing device. The sequence data in the cloud computing environment may be shared according to permissions. Further, the sequence data may be modified or annotated by authorized secondary users.

A technique is disclosed for sample management for use in conjunction with sequencing devices that sequence biological samples, e.g., DNA and RNA. A sequencing device or a network of sequencing devices may be scheduled according to the characteristics of the samples in queue and the capabilities and availability of sequencing devices. Biological samples may be automatically queued and loaded via a sample distribution system. A sample distribution system may be used to reduce operator intervention.

A first pulse sequence is executed on an imaging portion of an object to be examined using a multiple receiving coils including a plurality of receiving coils to obtain sensitivity images 701 to 703, each of n in number, which is smaller than the number of examination image. When those sensitivity images are calculated, NMR signals are measured only in a low-frequency region of a k space. Next, a second pulse sequence is executed while phase encoding steps are thinned out to acquire examination images 704 and 705, each of m in number (m>n), of the object with each receiving coil. When sensitivity distributions 707 and 708 are generated on the basis of sensitivity images 701 to 703, if a sensitivity distribution on a slice corresponding to examination images 704 and 705 is not yet measured, it is calculated with a slice interpolation processing on the basis of sensitivity distributions 701 to 703, and an aliasing artifact in examination images 704 and 705 are removed using sensitivity distributions 707 and 708 with a matrix calculation.

This invention relates to a method of encoding a path in layered form so as to allow partial decoding and progressive rendering while decoding. The path is made of an original sequence of original draw commands, each corresponding to an original portion of a drawing. The method of encoding includes transforming at least one original draw command into an approximating draw command according to a geometrical approximation of the corresponding original portion of a drawing, to obtain a reduced sequence, encoding the reduced sequence into an encoded reduced sequence, and encoding a reconstruction information set representing the difference between the reduced sequence and the original sequence.

Methods, compositions, systems and kits to introduce a controlled-number of molecular barcodes onto DNA fragments by reducing redundant molecular barcodes formed in template-dependent primer extension reactions, and to find variant frequencies from both strands of DNA. The methods, compositions, systems and kits described herein may include, or include the use of, one or more single-stranded DNA specific nucleases that cleave the single-stranded regions containing unmatched base pairs in amplification products.
