An apparatus, system, and method are disclosed for caching data on a solid-state storage device. The solid-state storage device maintains metadata pertaining to cache operations performed on the solid-state storage device, as well as storage operations of the solid-state storage device. The metadata indicates what data in the cache is valid, as well as information about what data in the nonvolatile cache has been stored in a backing store. A backup engine works through units in the nonvolatile cache device and backs up the valid data to the backing store. During grooming operations, the groomer determines whether the data is valid and whether the data is discardable. Data that is both valid and discardable may be removed during the grooming operation. The groomer may also determine whether the data is cold in determining whether to remove the data from the cache device. The cache device may present to clients a logical space that is the same size as the backing store. The cache device may be transparent to the clients.

A method and apparatus for synchronizing a client-side information store with a server-side database in a client/server architecture are disclosed. The method includes receiving data and receiving a script. The script defines a function of a control, and the function allows the control to perform an operation using the data.

For a text message received by a mobile terminal, some or all of the message is converted to voice-based content, depending upon the user's preference or upon the capability of the wireless device's display. When the display of the mobile terminal is too small to accommodate a large text-based message, a software module converts the text-based content to voice-based content. The voice-based content is then output to a speaker in the wireless device. For received messages of more than one type of content, only the portions of the message that are within the capabilities of the receiver are outputted, or converted to another type of content if possible.

The method comprises the steps that issuing verification equipment receives an education degree issuing affair; the issuing verification equipment obtains a historical blockchain identification from a degree blockchain of a degree stakeholder, and receives a compliance verification demand of the education degree issuing affair; the issuing verification equipment obtains a digital signature and an effective token of an issuer; the issuing verification equipment generates an effective block according to the compliance verification demand; finally the issuing verification equipment issues the effective block to the degree blockchain and carriesout the updating of the education blockchain. The method can solve a problem that the degree information querying efficiency is low.

A database management and indexing technique provides coherent access to and update of dynamic configuration information stored in a database associated with a multiprocessing environment of an aggregation router. The multiprocessing environment comprises a forwarding engine configured as a computing matrix of processors that operate on packets in a parallel as well as a pipeline fashion. A unique handle, i.e., a virtual common coherency index (VCCI) value, is associated with an interface regardless of whether it is a virtual or a physical interface. When a packet enters the computing matrix, it is classified and assigned a VCCI value based upon the interface over which it is received at or transmitted from the router. The assigned VCCI value is then passed along with the packet to each feature that processes the packet.

The invention is concerned with the multiple address accessing method, it includes: selecting the forecast outburst launching time slot during the interception channel in spare; monitoring the some micro-time slots before the forecast outburst launching time slot, it is available, transmits one or more of the forecast outburst grouping begin with it, otherwise, repeating the first step; the interception channel time slot transmit the operation grouping if no other forecast outburst grouping received, otherwise, repeating the first step. The invention improves the speed of the channel connection, the throughput volume of the net and reduces the collision ratio, the grouping delay, and insures the fairness.

A high-performance gridded database protocol for storing, arranging, and extracting gridded data includes associating values for a single grid cell and storing them together to extract as many useful values as possible from a single read operation. Gridded data is stored in a geographically-indexed cylindrical grid that permits efficient data extraction for a particular location while maximizing efficiency of read operations. Cylinders of values are built by grouping grids that are related to each other so that when data for a location is to be extracted, a minimal number of read operations is needed to retrieve an entire stack of data relevant to the location.

The present invention provides an apparatus and method to reduce the memory footprint of a processor architecture by structuring processor code to be stored in an external device, and transferring into the processor certain code and associated data as it is needed. The processor code or algorithm is divided into a controlling piece and a working piece. The controlling piece can be located on a low-MIPS, high memory-footprint device, whereas the working piece can be located on a high-MIPS, low memory-footprint device. The working piece can also be broken down into phases or segments, which are put in a data store. The segments are then transferred, on an as-needed basis along with associated data, from the store into the constrained memory of the low memory-footprint device. Transfer is facilitated by a segment manager which can be processed from the low-MIPS device, or alternatively from the high-MIPS device.

The invention provides a virus vector capable of realizing polygene editing of plants as well as a construction method and application of the virus vector, and relates to the technical field of gene editing of the plants. According to the virus vector, tRNA and sgRNA are sequentially linked to form unit sequences, and the unit sequences are linked with vectors pCE2; a target sequence of a target gene is inserted between the tRNA and sgRNA of each unit sequence by virtue of a ''golden-gate'' cloning method, the multiple unit sequences are linked and arrayed in series to form a series-wound sequence, the series-wound sequence is inserted into a TRV2 virus vector, after plants capable of overexpressing Cas9 proteins are infected by TRV, and a tRNA-sgRNA expression sequence unit assembled withdifferent unit sequences is transcribed, thereby finishing a polygene editing process, so that editing of multiple genes or combined editing of different genes according to targets can be realized. According to the construction method, the expression quantity of mRNA capable of being translated into normal protein sequences in the plants is lower, a gene silencing phenotype is relatively stable,and meanwhile, multiple genes can be precisely knocked out in a targeting manner.

The invention provides an emergency power conversion system of a transformer substation. A mobile emergency power conversion device and a primary cable transferring device are timely dispatched to a designated position through a management center. After the mobile emergency power conversion device and the primary cable transferring device are dispatched to the designated position, a main transformer-mobile emergency power conversion device-primary cable transferring device-feeder line cable wiring loop can be formed quickly. By virtue of the wiring loop, an access preparation work can be madebefore a feeder line (user) is powered off, so that the outage influence on the feeder line (user) is reduced to the minimum. Therefore, the emergency power conversion system of the transformer substation can be quickly and effectively connected, the power failure time of the user is reduced, and the problems of difficulty in power failure, long construction period and wide power failure range caused by transformation of the transformer substation equipment are effectively solved.
