Compositions and methods for rapid and highly efficient characterization of genetic diversity in organisms are provided. The methods involve rapid sequencing and characterization of extrachromosomal DNA, particularly plasmids, to identify and isolate useful nucleotide sequences. The method targets plasmid DNA and avoids repeated cloning and sequencing of the host chromosome, thus allowing one to focus on the genetic, elements carrying maximum genetic diversity. The method involves generating a library of extrachromosomal DNA clones, sequencing a portion of the clones, comparing the sequences against a database of existing DNA sequences, using an algorithm to select said novel nucleotide sequence based on the presence or absence of said portion in a database, and identification of at least one novel nucleotide sequence. The DNA sequence can also be translated in all six frames and the resulting amino acid sequences can be compared against a database of protein sequences. The integrated approach provides a rapid and efficient method to identify and isolate useful genes. Organisms of particular interest include, but are not limited to bacteria, fungi, algae, and the like. Compositions comprise a mini-cosmid vector comprising a stuffer fragment and at least one cos site.

The mass spectrometer is preferably a Fourier Transform Ion Cyclotron Resonance mass spectrometer, and the resulting ion separation instrument may further include therein various combinations of ion fragmentation, ion mass filtering, ion trap, charge neutralization and / or mass reaction instrumentation.

A method of making a wall block and a mold box therefore. The wall block design maximizes the use of the mold box. The method produces wall blocks having a large surface area front face compared to the front face size of prior art blocks. The blocks have about one third more front surface area. This results in faster construction of walls and a faster construction sequence. The method of making the blocks makes efficient use of mold space and material, resulting in higher production yields and / or higher total daily production square footage.

A system and method for unorchestrated determination of data sequences using “sticky byte” factoring to determine breakpoints in digital sequences such that common sequences can be identified. Sticky byte factoring provides an efficient method of dividing a data set into pieces that generally yields near optimal commonality. This is effectuated by employing a rolling hashsum and, in an exemplary embodiment disclosed herein, a threshold function to deterministically set divisions in a sequence of data. Both the rolling hash and the threshold function are designed to require minimal computation. This low overhead makes it possible to rapidly partition a data sequence for presentation to a factoring engine or other applications that prefer subsequent synchronization across the data set.

The shape of nanopore overcomes nucleotide conformation effect on the identification as bases translocate through the nanopore.

An apparatus and method for rendering multiplanar reformatting (MPR) images of volume data to be displayed to a user. The apparatus may comprise a conventional personal computer system having a central processing unit (CPU) coupled to a system memory for storing the volume data and a graphics processing unit (GPU) having a GPU memory connected to the computer bus. The computer system CPU is configured to predict an MPR image which may be required for display at a future time and to identify blocks of voxels comprising the volume data which will be needed to render the predicted MPR image. The CPU is further operable to retrieve these blocks from the system memory and to queue them for transfer to the GPU memory. The transfer of blocks from the queue to the GPU memory is controlled by a scheduler such that at least some of the queued blocks are transferred to the GPU memory prior to the predicted MPR image becoming required for display. The GPU retrieves blocks from the GPU memory and renders corresponding image parts for assembly into the predicted MPR image should it become required for display.

A fuel injection valve for an internal combustion engines is proposed, in which the control of the fuel injection valve member is controlled through the control of the pressure of a control chamber (25). This chamber is either relieved by means of a control valve (31) or is subjected to a high pressure, which brings the fuel injection valve member into the closed position. At the same time as the relief of the control chamber, a valve member (33) of a safety valve (32) that controls the fuel supply to the fuel injection valve is opened so that upon opening of the fuel injection valve, high-pressure fuel simultaneously also can travel by way of a pressure line (12) from a high-pressure fuel reservoir (14) to the injection openings (8) of the fuel injection valve (1). After the end of the injection, the valve member (33) is closed again, together with the closing of the fuel injection valve member (5). Consequently, in the event of a malfunction, unwanted fuel is prevented from reaching injection for a long period of time and consequently possibly destroying the associated engine due to overdosing.

Described herein are inexpensive high throughput methods to convert a target single stranded DNA (ssDNA) such that each nucleotide (or base) adenine (A), thymine (T), guanine (G) and cytosine (C) is converted to a pre-determined oligonucleotide code, with the sequential order preserved in the converted ssDNA, or RNA. The method does not require the use of DNA polymerases during the cycles and involves the use of an oligonucleotide probe library with repeated cycles of ligation and cleavage. At each cycle, one or more nucleotides on one end (e.g., either the 5′ end or the 3′ end) of a target, e.g., ssDNA, are cleaved and then ligated with the corresponding oligonucleotide code at the other end of the target ssDNA.
