Abstract: A variety of refueling devices, systems and methods are disclosed for use in in-flight refueling. In one example one such device is towed by a tanker aircraft via a fuel hose at least during in-flight refueling, and has a boom member with a boom axis. The boom member enables fuel to be transferred from the fuel hose to a receiver aircraft along the boom axis during in-flight refueling. The device maintains a desired non-zero angular disposition between the boom axis and a forward direction at least when the refueling device is towed by the tanker aircraft in the forward direction via the fuel hose.

Abstract: Techniques for providing dependency resolution for lazy snapshots in a storage cluster with a delta log-based architecture. The techniques include creating a dependency relationship between a parent metadata page and a child metadata page, receiving one or more new delta updates of the parent metadata page, and writing, to a metadata delta log, the new delta updates of the parent metadata page as specialized delta update entries that preserve or maintain the new delta update values and their corresponding original (old) delta update values. By preserving or maintaining both the new delta update values and the corresponding old delta update values of the parent metadata page in the metadata delta log, constraints pertaining to the order of de-staging the delta updates of the parent and child metadata pages can be reduced.

Abstract: In at least one embodiment, processing can include acquiring a spinlock on a cached copy of a metadata (MD) page includes a field stored in two cache lines; updating a register to include an updated value of the field; determining whether a first portion of the updated value of the register is non-zero, wherein two portions of the updated value of the field as stored in the register correspond to the two cache lines; and responsive to determining that the first portion of the updated value of the register is non-zero, performing processing including: storing the first portion of the updated value of the field from the register in the first cache line; and subsequent to performing storing the first portion, storing the second portion of the updated value of the field as stored in the register in the second cache line.

Abstract: A method is used for improving performance in a storage system during deduplication. A processor receives a request to write data. A determination is made that the data can be deduplicated. A non-exclusive lock for a page in storage with a reference count of the data may be obtained, and an instruction to increment the reference count for the data may be stored in a metadata journal. The non-exclusive lock for the page may be released.

Abstract: A multi-analyte sensor includes a body having a proximal end and a distal end. A plurality of strips is connected to one end of the body and a plurality of electrical conductors run through the body and into the plurality of strips. Exposed portions of first and second electrical conductors running through first and second strips are coated with analyte-responsive materials, such as a first molecular imprinted polymer (MIP) and a second MIP, respectively. The first MIP has binding sites for a first target analyte and the second MIP has binding sites for a second target analyte. The multi-analyte sensor may be part of a sensing device that also includes a controller and a data store.

Abstract: Among other things, a stimulation strategy can be customized for a cochlear implant implanted in an individual by testing at least a pair of electrodes selected from an array of electrodes associated with the cochlear implant. Testing the at least a pair of electrodes includes applying a first stimulation to the at least a pair of electrodes using a first pair of pulse trains that are out of phase, and applying a second stimulation to the at least a pair of electrodes using a second pair of pulse trains that are out of phase. A determination is made on whether the at least a pair of electrodes stimulate the same neural population based on a sensitivity of the individual to detect a perceived difference between the two pairs of pulse trains. The one or more electrodes of the array of electrodes are selectively stimulated based on the determination.
