Abstract: A multiprocessing transaction recovery manager, operable with a transactional application manager and a resource manager, comprises a threadsafety indicator for receiving and storing positive and non-positive threadsafety data of at least one transactional component managed by one of the transactional application manager and the resource manager; a commit protocol component for performing commit processing for the at least one transactional component; and a thread selector responsive to positive threadsafety data for selecting a single thread for the commit processing to be performed by the commit protocol component. The thread selector is further operable to select plural threads for the commit processing to be performed by the commit protocol component responsive to non-positive threadsafety data.

Abstract: A rifle having a receiver formed of upper and lower receiver portions attached to one another has one or more elastic bodies positioned between facing surfaces of the upper and lower receiver portions. The elastic bodies reduce play or lost motion between the upper and lower receiver portions for improved accuracy.

Abstract: A compositionally graded semiconductor device and a method of making same are disclosed that provides an efficient p-type doping for wide bandgap semiconductors by exploiting electronic polarization within the crystalline lattice. The compositional graded semiconductor graded device includes a graded heterojunction interface that exhibits a 3D bound polarization-induced sheet charge that spreads in accordance with ??(z)=??·P(z), where ??(z) is a volume charge density in a polar (z) direction, and ? is a divergence operator, wherein the graded heterojunction interface is configured to exhibit substantially equivalent conductivities along both lateral and vertical directions relative to the graded heterojunction interface.

Abstract: The present invention provides compositions and methods for noninvasive delivery of therapeutic agents across an intact tympanic membrane. For example, the compositions include a penetration enhancer which increases the flux of a therapeutic agent (e.g., antibiotic) across the tympanic membrane. Such compositions are particularly useful in the treatment of otitis media. Additionally, the composition may include a sustained release agents that, in some embodiments form sustained release reservoirs, in situ, once administered to a patient.

Abstract: The invention provides an improved method for obtaining information about DNA analysis of samples of uncertain origin by establishing the likelihood that they arose in certain manners compared with other possible manners. In this way all of the analysis information is taken into account and likelihood ratios are provided to express the results. The invention is particularly useful in analysing small DNA samples or DNA samples where the contribution from one or more sources is small.

Abstract: A machine for accurately cutting tiles, blocks of concrete, clay, blocks of stone and stone materials, wood and wooden materials is described. It may include a support stand which at its top supports a removable bed structure. The bed includes a motor-driven cutting disc recessed-mounted axially along pillow blocks such that a substantial portion of the cutting disc is projected above the bed surface and its mode of rotation is about a fixed centralized axis. Trolley track rails situated on distal ends of both long sides of the bed allow for lateral movement of the trolley above the bed surface to facilitate the cutting operation. During operation the object secured safely on the trolley which is manually moved towards the cutting disc while a perforated shower head sprays water onto the work piece. Water is filtered and recycled back to the shower via the bin situated below the cutting disc and thence to the recycle and filter unit.

Abstract: A method for controlling injection of a reductant into an exhaust system of an internal combustion engine includes determining the temperature and pressure of reductant supplied to a reductant injector. The method also determines a maximum reductant flow rate as a function of the reductant temperature and pressure and controls operation of the injector as a function of the maximum reductant flow rate.

Abstract: An integrated circuit 2 comprises a functional circuit 4, 6 which is arranged to operate in response to an operational clock signal having an operational clock frequency. To conserve power, the clock signal is distributed across the integrated circuit 2 at a distribution clock frequency which is less than the operational clock frequency. A clock converter 10 is provided to convert the distribution clock signal into the operational clock signal for controlling operation of the functional circuit 4, 6.

Abstract: A trace module generates timestamps while tracing characteristics of a data processing apparatus or processing is performed by the data processing apparatus. When a predetermined event occurs, a timestamp request flag is set to indicate that a timestamp request is pending. Upon generation of a following trace packet, it is determined whether the timestamp request flag indicates that a timestamp request is pending, and if a request is pending then a timestamp is generated corresponding to the following trace packet, and the timestamp request flag is set to indicate that there is no pending timestamp request.

Abstract: A data processing apparatus is disclosed including trace logic for monitoring behavior of a portion of said data processing apparatus and prediction logic for providing at least one prediction as to at least one step of the behavior of the portion of the data processing apparatus. The trace logic monitors behavior of the portion of the data processing apparatus, determines from the monitored behavior whether the at least one prediction is correct, and outputs a prediction indicator indicating whether the at least one prediction is correct.

Abstract: A system and method for heating a purging fluid contained in a portable oil sump or reservoir, and pumping the hot purging fluid through a bearing housing in order to purge the bearing and bearing housing of accumulated hardened grease, sludge, and debris. The heated purging fluid can then be suctioned into the sump or reservoir, screened and filtered, and re-circulated through bearing housing to continue purging the bearing and bearing housing.
