Abstract: A method to provide information from a first information storage and retrieval system to a second information storage and retrieval system, where the first information storage and retrieval system comprises (N) PPRC adapters and information. The method generates and saves an Established Path Bitmap which recites the (N) PPRC adapters, and generates an Available Path Bitmap. If a PPRC adapter is in communication with the secondary storage system, then the method adds that adapter to the Available Path Bitmap. The primary information storage and retrieval system generates a PPRC task comprising a flag set to “off”. The method copies the Available Path Bitmap as a Working Bitmap, and generates a PPRC request comprising a flag set to “on”, selects one of the adapters recited in the Working Bitmap, and provides the PPRC request to that selected adapter. The method then once attempts to provide information to the second information storage and retrieval system using the selected adapter.

Abstract: Computer networks are provided with a resource efficient ability to generate link performance statistics. To calculate the average link utilization per I/O operation, a first counter accumulates the number of I/O operations processed by a link and a second counter accumulates the time required by the link to complete each I/O operation. The second value is then divided by the first value. The number of operations per second for a link may be computed by dividing the first number by a predetermined period of time and the average number of operations using the link may be computed by dividing the second number by the predetermined period of time. A third counter may be employed to accumulate the number of bytes transferred by a link during each I/O operation. Then, average size of an I/O operation may be computed by dividing the third number by the first number and the average bandwidth per link operation may be computed by dividing the third number by the predetermined period of time.

Abstract: A method and apparatus for and article of manufacture for simulating workloads experienced by multiple partitions in a virtualized system are provided. A master workload driver initiates, coordinates and regulates one or more workload drivers that execute one or more workload simulation tasks in a logical partition. Further, each workload driver may be configured to report a measure of performance regarding the workload to the master control driver where results of many workload drivers may be correlated and analyzed. A configuration file specifies the characteristics of each simulation. Further, the rate and nature of workloads may be adjusted dynamically during a given simulation to model the performance under different real-world scenarios of different computational loads that may be experienced by the virtualized system.

Abstract: Provided herein are conjugates, kits, articles of manufacture and methods for detection, diagnosis and treatment by photodynamic therapy of certain undesired biological substrate targets, including, but not limited to bacteria, viruses, and other pathogenic microorganisms, tumors and hyperproliferative tissue. In particular, the conjugates provided include a fluorophore or photosensitizer linked to a targeting moiety and a quenching agent in such a way that activation of the fluorophore or the photosensitizer is quenched unless the targeting moiety is bound to a target, whereupon the quenching agent dissociates or moves away from the photosensitizer, enabling activation of the photosensitizer upon irradiation with light of a suitable wavelength.

Abstract: A method of manufacture and medical apparatus that provides an apparatus useful in illuminating at least a portion of a lumen of a body. The apparatus includes an elongated flexible member and a polymer encasement portion encasing a plurality of light emitters. The light emitters may be electrically coupled to one another without the use of wire bonds, and in some embodiments may be coupled without intervening electrical paths or traces. A maximum cross-sectional dimension of the polymer encasement portion may be less than twice a dimension of one of the light emitters. In some embodiments the maximum cross-sectional dimension is less than or equal to the sum of the dimension of one of the light emitters and a marginal dimension by which an outer portion of the polymer encasement portion extends beyond the light emitter. Light emitters may be arranged linearly, helically or in partially overlapping back-to-back relation.

Abstract: A mechanical vessel may effectively and simultaneously displace a first undesired gas from within water with a second desired gas, and remove at least one alkaline species and oily matter from the water. The vessel raises the pH of the water and reduces the lime requirement for subsequent lime softening. The vessel receives the water containing the first gas and passes the water through a series of gasification chambers. Each gasification chamber may have a mechanism that ingests and mixes a second gas into the water thereby physically displacing at least a portion of the first gas into a vapor space at the top of each gasification chamber from which it is subsequently removed. There is an absence of communication between the vapor spaces of adjacent chambers. An acid is added to remove the alkaline species, where the first gas is an optional by-product that is also removed.

Abstract: It has been discovered that a mechanical flotation system (10) having only two cells (18, 20) can be nearly as efficient as one having more cells, yet provide an apparatus with a considerably smaller footprint, significantly reduced capital and operating costs, as well as be resistant to floating oil recovery platform wave effects. The dual-cell mechanical flotation system (10) has, in sequential order, an inlet chamber (16) and two gasification chambers or cells (18, 20), each with at least one gas ingestion and mixing mechanism (32), and a discharge chamber (24). A common primary skim collection channel (40) atop the partition (44) dividing the gasification chambers (18, 20) efficiently channels away the bulk of the floating collected matter.
