Abstract: Presented are embodiments of methods and systems for library-based compilation and dispatch to automatically spread computations of a program across heterogeneous cores in a processing system. The source program contains a parallel-programming keyword, such as mapreduce, from a high-level, library-oriented parallel programming language. The compiler inserts one or more calls for a generic function, associated with the parallel-programming keyword, into the compiled code. A runtime library provides a predicate-based library system that includes multiple hardware specific implementations (“variants”) of the generic function. A runtime dispatch engine dynamically selects the best-available (e.g., most specific) variant, from a bundle of hardware-specific variants, for a given input and machine configuration.

Abstract: The invention relates to a method of estimating symbols carried by a digital signal that is received by a receiver over a communication channel (5), said symbols being multiplexed on orthogonal frequency sub-carriers. The inventive method comprises the following steps in relation to each symbol carried by the digital signal, consisting in: performing at least two transforms towards the frequency domain (8,9) on a portion of the received signal essentially corresponding to the symbol, said transforms being performed with a determined time lag (10) therebetween; estimating the parameters (r0, r1, . . . , rn, r?0, r?1, . . . , r?n) of the communication channel from pre-determined binary information contained in the digital signal; and estimating the symbol from a combination of the result of each of the transforms performed and the estimated communication channel parameters.

Abstract: A test circuit used for determining a fault in a memory device. The test circuit includes a read circuit configured to read memory cell contents in a memory device at a first time instant and second time instant. The test circuit includes a comparator that compares the contents at the first and second time instants. If the contents are different from one another, the comparator indicates that a fault has occurred. Test methods are also used to determine if a fault has occurred in a memory cell.

Abstract: Hitless Switching provides a method of delivering data to a remote point in a reliable fashion. However, no guarantee or acknowledgement is provided that data has been written to a remote storage device. This is problematic for remote data mirroring. Apparatus and methods are provided to guarantee that data arriving at a remote terminal is correctly stored. Interaction with hitless switching and remote optical mirroring systems are described.

Abstract: Novel growth peptides derived from protein factors having molecular weights of about 22 and 45 kDa stimulate mitogenic activity of epithelial, but not fibroblastic cells, in particular, kidney epithelial cells. A source of the factors is scrape-wounded kidney epithelial cells in culture. Synthetic peptides having sixteen amino acids or less, in particular a hexapeptide, YPQGNH (SEQ ID NO: 2) maintain the mitogenic activity. The peptide AQPYPQGNHEASYG (14-Ser) (SEQ ID NO: 15) is effective in reversing acute renal failure in animals. The growth-promoting characteristics of the 22 and 45 kDa proteins and the peptides are useful in treating and diagnosing patients with kidney disease. Nucleotide sequences that encode the factor are useful to develop probes to locate similar factors, to identify genetic disorders involving the factor, and to produce the factor by genetic recombinant methods. The nucleotide sequences and fragments thereof, are also useful for diagnosis and treatment of kidney disorders.

Abstract: An autocrine crystal adhesion inhibitor called CAI is an anionic, sialic acid-containing glycoprotein secreted by kidney epithelial cells that blocks adhesion of calcium oxalate monohydrate (COM) crystals to the cell surface. Novel amino acid sequences are shown for the amino-acid terminus and 6 interval fragments. Persons may be classified according to risk of developing kidney stones, by measuring the amount of CAI in a biological sample. Treatment efficacy is also monitored by this method. CAI is administered in vivo to prevent nephrolithiasis. A rapid, simple assay to detect agents that inhibit adhesion of COM crystals to the surface of kidney epithelial cells is characterized.

Abstract: A column flotation cell includes a fluid vessel, an exteriorly mounted microbubble generator, conduits for conducting a pressurized mixture of bubbles and liquid from the generator to the vessel, features for inhibiting the coalescence and enlargement of the bubbles prior to their introduction into the vessel, and an arrangement for introducing the bubble/liquid mixture into the vessel and for distributing the mixture uniformly throughout the vessel cross-section. Coalescence and enlargement of the bubbles are inhibited by limiting the length of the mixture-conducting conduits, and by designing the conduits so as to provide a substantially uniform and continuous flow diameter. The uniform and continuous nature of the flow diameter reduces local disturbances of fluid flow which would otherwise occur at discontinuities in the flow path, tending to cause coalescence and enlargement of the bubbles.

Abstract: In a conventional sewing machine, as the take-up lever is driven by the take-up lever crank, the take-up lever does not keep its uppermost position during the feed motion of a work fabric. Accordingly, the length of the thread path extending from the thread supply source to the eye of the needle varies remarkably during feed motion, and thus the needle thread equivalent to the amount consumed by stitch feed motion cannot be extracted from the supply source. In the present automatic needle thread supply control system, during a specific period from a time before finishing of each feed motion to a time when the needle reaches the throat plate, the take-up lever is held at its uppermost position. During a given period corresponding to the comparatively latter half of the specified period, thread supply stopping is released, whereby the needle thread equivalent to the amount consumed by each stitch feed motion can be extracted certainly from the supply source toward the take-up lever.

Abstract: A fuel cap for use in a vehicle fuel system filler neck is provided. The fuel cap includes a closure for closing the filler neck and a pressure relief valve that is movable between a filler neck-venting position and a non-venting position. A roll-over control assembly is provided for selectively utilizing liquid fuel and fuel vapor in the filler neck to exert a closing force on the pressure relief valve so that the pressure relief valve is moved to its non-venting position to block discharge of liquid fuel to the atmosphere through the pressure relief valve during vehicle rollover. The roll-over control assembly cooperates with the pressure relief valve to define a venting control chamber for containing fuel and a fuel vapor in a predetermined region to permit the fuel and fuel vapor to exert the closing force on the pressure relief valve. A passageway is provided for establishing communication of fuel and fuel vapor in the filler neck with the venting control chamber.

Abstract: A roll-over valve is provided for use in a vehicle fuel system having an outlet for discharging fuel vapor. The roll-over valve includes a hollow valve member that terminates in a distal tip and includes a side wall. The distal tip is formed to include a top aperture and the side wall is formed to include at least one side aperture. The top aperture and side aperture cooperate to prevent the formation of a low pressure area that might otherwise be formed over the distal tip to prevent the hollow valve member from prematurely sealing the outlet. A roll-over ball is provided for moving the distal tip from an outlet-opening position to an outlet-closing position in response to tilting of the hollow valve member during vehicle roll-over conditions. A ball is provided in the hollow valve member for closing the top aperture during a selected first range of tilting positions of the hollow valve member.

Abstract: A keyed lever handle for a cylindrical lock comprises a handle body which is rotatably mounted by its neck on the knob sleeve of the lock and is removably held by a retainer and is connected for rotation with the sleeve by a driver which releases under excess torque, either yieldingly or by break-away of a driver lug. An outward-extending body shell telescopically receives and supports an outer handle shell integral with a handle lever. The outer shell has an inward-extending end flange spaced from the end face of the body shell to define therebetween an inward-opening groove which receives a retainer for an end face closure mounted in the cylindrical open end of the assembled shells. The retainer may be a separate snap ring or an integral flange on the closure. The closure member receives a key-operated and removable core, and its rotative mounting permits different orientations to suit the hand of the door, and also permits the lever handle to rotate when drive is released under excess torque.
