Write-behind optimization of covering cache
Data base performance is improved using write-behind optimization of covering cache. Non-volatile memory data cache includes a full copy of stored data file(s). Data cache and storage writes, checkpoints, and recovery may be decoupled (e.g., with separate writes, checkpoints and recoveries).

Aggregate writes reduce data file fragmentation and reduce the cost of snapshots. Performing write-behind operations in a background process with optimistic concurrency control may support improved database performance, for example, by not interfering with write operations to data cache. Data cache may store (e.g., in metadata) data cache checkpoint information and storage checkpoint information. A stored data file may store storage checkpoint information (e.g., in a file header). |

Generating copies through interoperability between a data storage management system and appliances for data storage and deduplication
Illustrative storage manager and media agent are enhanced to interoperate with deduplication appliances. Advantages are realized when making secondary and tertiary copies and also when restoring from a deduplication appliance. Tiered indexing minimizes how much data is retained and stored at media agents. Tiered indexing enables media agents to efficiently extract needed information from deduplication appliances to make tertiary copies and to restore backed up copies. Interoperability techniques include media agents generating separate data streams to the deduplication appliance. Each data stream carries a different kind of data, e.g., payload data, metadata content, or high-level index information. On initial backup, the media agent instructs the deduplication appliance to deduplicate the payload data stream but not the other data streams, thus intelligently applying resources to data most likely to benefit from deduplication. For tertiary copies (copies of pre-existing copies at the deduplication appliance), the media agent avoids handling payload data altogether. |

Transposase-mediated imaging of the accessible genome
Methods for labeling and imaging the accessible genome using a transposase are disclosed. In some embodiments, a bifunctional transposase complex or transposome is used to insert adaptors comprising chemical tags selectively at accessible sites in the genome where active regulatory DNA is located. Various chemical tags can be used for labeling DNA at insertion sites, including, for example, fluorescent dyes for fluorescence imaging, metal particles for electron microscopy or magnetic manipulation of DNA, isotopic labels, or biotin or other ligands, haptens, substrates, or inhibitors that are recognized by streptavidin, antibodies, enzymes, or receptors. Labeling DNA in this manner can be used to provide spatial information regarding the positioning of regulatory DNA in the genome and makes possible the imaging and sorting of cells based on the status of their regulatory DNA. |

Recombinant herpes simplex virus and use thereof
The invention relates to the field of virology and tumor therapy. In particular, the present invention provides a recombinant herpes simplex virus (HSV) capable of specifically replicating at a high level in a tumor cell and effectively killing the tumor cell, but replicating at low levels in normal cells, thereby the recombinant herpes simplex virus of the present invention not only has high lethality against tumor cells, but also has significantly decreased side effects (especially neurotoxicity). Further, the present invention relates to a viral vector constructed based on the recombinant herpes simplex virus, a pharmaceutical composition comprising the recombinant herpes simplex virus or the viral vector, and the use of the recombinant herpes simplex virus or the viral vector. The recombinant herpes simplex virus of the present invention can be used to infect and kill tumor cells, and can be used for gene drug delivery into tumor cells for gene therapy. |
