Layering a distributed storage system into storage groups and virtual chunk spaces for efficient data recovery
Technology is disclosed for storing data in a distributed storage system using a virtual chunk service (VCS). In the VCS based storage technique, a storage node (“node”) is split into multiple VCSs and each of the VCSs can be assigned a unique ID in the distributed storage. A set of VCSs from a set of nodes form a storage group, which also can be assigned a unique ID in the distributed storage. When a data object is received for storage, a storage group is identified for the data object, the data object is encoded to generate multiple fragments and each fragment is stored in a VCS of the identified storage group. The data recovery process is made more efficient by using metadata, e.g., VCS to storage node mapping, storage group to VCS mapping, VCS to objects mapping, which eliminates resource intensive read and write operations during recovery. |

Redo log for append only storage scheme
A new snapshot of a storage volume is created by suppressing write requests. Once pending write requests from the computing nodes are completed, storage nodes create a new snapshot for the storage volume by allocating a new segment to the new snapshot. Data is written in segments and Metadata is stored in the segments indicating LBAs of data stored therein and offsets within the segments at which data for LBAs are stored. For write requests, index entries are stored in an index buffer for a segment and written to the segment when the buffer is full. A redo entry is created in a redo buffer for multiple storage volumes and slices for each write request. Write requests are acknowledged when the redo buffer is written to redo segments on a storage device. On restart, index buffers are reconstructed from the redo segments if needed. |

The presently disclosed subject matter provides methods using mass spectrometry for direct profiling of N-linked glycans from a biological sample. In addition, the embodiments of the present invention also disclose novel methods, known as targeted analyte detection (TAD), for improving the detection limit of MALDI-MS. These methods take advantage of the carrier effect of the added standard analytes, which occurs due to the generic sigmoidal shape of the calibration curve.

At certain ranges of exogenous concentration, the increment in the sensitivity overcomes the standard deviation, resulting in an improved LOD. Theoretically, exogenous concentrations approximately at 1 LODorig would generate the optimum LOD improvement. TAD is a cost-effective LOD improvement method, which is not limited to a certain group of analytes, or detection methods or instruments. It can be applied to enhance the detection of any analyte with different detection methods, provided that the analyte of interest can be extracted or is available in synthetic form. |

Morris 80 plastic apollo bolt
When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for small game hunting, pistol crossbow fishing, recreational shooting and competition shooting. The major fault of the standard bolt commonly used with a pistol crossbow is, they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, because of their irretrievability from any commonly used target, they cannot be found and scored in any type of shooting competition. This ten inch bolt is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to securely hold the bow string in place. Standard pistol crossbow bolts do not have a nock. It has two ROUNDED WINGS and a stabilizing TAIL which creates an accurate and stable bolt flight. No other pistol crossbow bolt has rounded wings and a tail. These features allow this bolt to be easily viewed in flight. The shaft has a THREADED TIP to accept almost any type metal point. The major advantage of this new bolt over other patented bolts of this size is the rounded wings. The rounded wings gives this bolt added body weight. This added body weight requires additional point weight to balance with that heavier body weight. This heavier bolt body gives this bolt the added weight needed for knock-down power in small game hunting and, the necessary added weight for better water penetration when used for pistol crossbow fishing. |
