The method may further include removing at least a top portion and at least a bottom portion of the reaction effluent from the reactor vessel.

Abstract: Migrating data in a tiered storage system. The tiered storage system includes an upper tier with at least one storage device and a lower tier with at least one storage device. Data on a storage device includes one or more extents, and each extent contains one or more grains. I/O activity of grains is recorded during a predefined time interval. For each extent, a mean heat value over grains in the extent during the predefined time interval is calculated from the recorded I/O activity, where a heat value is a numerical indication of frequency of access of a grain, and a spike heat indicator, which measures non-uniformity of heat values of grains in the extent is calculated. Two extents with mean heat values that differ at most by a predefined threshold are identified, and the extent with a greater spike heat indicator is migrated to an upper tier.

The core of the nanofiber comprises a biocompatible polymer together with an antibacterial agent such as a quaternary ammonium compound, for example benzyl dimethyl tetradecyl ammonium chloride (BTAC). Surrounding the core is shell comprised of a bacterially degradable polymer, which is susceptible to break-down by bacterial enzymes such as lipase, or to acidic pH conditions. The shell may comprise, for example, polycaprolactone (PCL) and poly(ethylene succinate) (PES).

Abstract: A mechanism is provided in a data processing system for asynchronous replication. The mechanism creates a record in a write log in a host computing device for a write command and marking the record as uncommitted. The mechanism maintains a copy of data to be written by the write command at the host computing device. The mechanism issues the write command from the host computing device to a primary storage controller at the primary storage site. Responsive to receiving an acknowledgement from the primary storage controller that the data have been written to the primary storage site, the mechanism marks the record as unreplicated. Responsive to receiving an acknowledgement from the primary storage controller that the data have been replicated to a secondary storage site, the mechanism erases the record in the write log and deleting the copy of data.

A method can comprise: receiving raw image data from an image capture device, segregating the pixel data into a base layer portion and an enhanced layer portion, reconfiguring the base layer portion expressed in the first color space values from a raw capture format into a pseudo second color space compression mechanism compatible format, and compressing the reconfigured base layer portion of first color space values. The raw image data can include pixel data are expressed in first color space values. The segregation can be based upon various factors, including a compression benefits analysis of a boundary location between the base layer portion and enhanced layer portion. The reconfiguring the base layer portion can include separating the base layer portion based upon multiple components within the raw data; and forming base layer video frames from the multiple components.

Abstract: A wax composition can be incorporated into a biomass mixture, such as a woody biomass mixture, for formation of pellets, such as wood fuel pellets. The addition of wax compositions with suitable amounts of n-paraffins relative to the amount of oil-in-wax can result in biomass pellets with improved properties, such as improved durability and/or reduced tendency to uptake moisture during storage. Addition of a suitable wax composition can also allow for formation of biomass pellets with improved properties while also reducing or minimizing the power requirements during pellet formation.

A user is initially classified as a human or non-human agent based on user request properties. Sensor data is received from the user device and used to determine whether the user is to be reclassified as a human agent or non-human agent. Based on the sensor data, the user is then reclassified as a human agent or non-human agent. A service is adapted based on the classification.

Abstract: A data migration management apparatus includes a data migration module, a decompression module, and a consolidation module. The data migration module determines a plurality of compressed extents on a source controller are subject to a data migration process to a target controller. The decompression module receives an input/output request at a storage virtualization controller, from a host application, after the data migration process has begun. A response to the input/output request includes decompressing one of the plurality of compressed extents on the source controller not yet migrated. The consolidation module executes the response to the input/output request and writes to the target controller from a single decompressed extent.
