Isolated DNA from Penaeus vannamei was digested with restriction enzymes, restriction fragments of genomic DNA inserted into a plasmid vector and screened for recombinant plasmids containing repeated sequences. Ten of the resulting isolates contained representatives of the same repeated element, a satellite sequence present in one or more blocks of tandemly repeated units. The cloned repeat units range in size from about 100 to 200 base pairs, more typically between about 139 to 188 base pairs. Embedded within each cloned repeat unit are 6 to 15 copies of a tandemly repeated pentanucleotide microsatellite. The genome of P. vannamei contains approximately one million copies of this satellite/microsatellite unit. The sequences are useful as markers for the selection of shrimp having a genetically-transmitted favorable growth characteristic, such as increased reproduction, enhanced growth rate, increased size, disease-resistance, and the ability to grow in colder waters, for improved aquacultured shrimp production. Hybridization of the marker to an isolated Peaneus shrimp mucleic acid molecule can be used to identify species, strains or individual shrimp having the desired characteristics. Once identified, these shrimps can be bred to shrimp having the same or an additional desired characteristic to produce a high quality, genetically superior seedstock or larvae useful for the economic production of farmed shrimp.

A first electronic representation of a financial instrument (10) complying with a first protocol is created (62). The first electronic representation is converted to a digital delivery format complying with a second protocol (74). The digital delivery format is delivered over an electronic data communication network (52). This enables information concerning the financial instrument to be delivered over the network in a predetermined format. The invention may be generally applied to a financial instrument such as a check (20).

A method and apparatus are provided for scheduling when each of a plurality of virtual connections supported by a transmit device will be serviced by the transmit device. The transmit device includes a transmission control unit that uses a plurality of calendars to schedule when each of the plurality of virtual connections will be serviced. Virtual connections with faster transfer rates are scheduled using higher granularity calendars, while virtual connections with slower transfer rates are scheduled using lower granularity calendars. Each entry in the calendars is associated with a time interval ('cell slot') during which the transmit device is able to service one virtual connection. During a given cell slot, linked lists associated with the calendar entries that correspond to the cell slot are added to a service queue, and the virtual connection at the head of the service queue is serviced. After a virtual connection is serviced, the next service time for the virtual connection is scheduled by attaching the virtual connection to the head of a linked list associated with the appropriate entry of the appropriate calendar. The appropriate entry is determined by incrementing a fixed-point 'desired service time' value that represents the cell slot for which the virtual connection was last scheduled, by a fixed-point inter-gap value that represents the how many cell slots ideally elapse between sequential service times of the virtual connection.

A mechanism for maintaining a consistent, periodically updated state in main memory without constraining normal computer operation is provided, thereby enabling a computer system to recover from faults without loss of data or processing continuity. In a typical computer system, a processor and input/output elements are connected to a main memory subsystem that includes a primary memory. In embodiments of the present invention, a read buffer is also appended to this main memory subsystem. During normal processing, a pre-image of data written to the primary memory may be captured by the read buffer. Data captured in the read buffer can restore the system to a previous checkpoint. This structure and protocol can guarantee a consistent state in main memory, thus enabling fault-tolerant operation.

A protection circuit inhibits saturation and damage of sensitive circuit elements (54) when an input signal goes out of a nominal input range. The protection circuit includes an out-of-range detector (52) which compares the input signal to reference levels to determine if it is within the range. If it is not, a control circuit (62, 64) substitutes a supplemental signal that is slightly out of range, but not so far out of range as to cause any substantial saturation. Supplemental signal sources that produce supplemental signals slightly outside the high and low ends of the range with error margins, not more than about 750 mV, that lie just outside the range; an out-of-range input is replaced by the supplemental signal with the closest value. The invention is particularly applicable to multi-step/subranging analog-to-digital/converters.

Polymeric films consisting of at least one layer of a thermoplastic polymer having thereon a layer of a dispersion of a particulate filler in a dispersant, the dispersant consisting of or containing a tackifier. The dispersion can form an outer layer or an internal layer of the films. Such films have good barrier properties to oxygen and other gases and are of particular use in the ensiling of vegetable matter such as hay and straw. If the dispersant is migratory and/or volatile it can enable the dispersion to concentrate, thereby enabling dispersions with low concentrations of filler to concentrate.
