A method, computer program product, and a data processing system for optimizing task throughput in a multi-processor system. A performance metric is calculated based on performance counters measuring characteristics of a task executed at one of a plurality of processor frequencies available in the multi-processor system. The characteristics measured by the performance counters indicate activity in the processor as well as memory activity. A performance metric provides a means using measured data at one available frequency to predict performance at another processor frequency available in the multi-processing system. Performance loss minimization is used to assign a particular task to a particular frequency. Additionally, the present invention provides a mechanism for priority load balancing of tasks in a manner that minimizes cumulative performance loss incurred by execution of all tasks in the system.

Compositions and methods for stabilizing rare cells in blood specimens, preserving the quality of blood specimens, and also serving as cell fixatives are disclosed which minimize losses of target cells (for example, circulating tumor cells) and formation of debris and aggregates from target cells, non-target cells and plasma components, thereby allowing more accurate analysis and classification of circulating tumor cells (CTC) and, ultimately, of tumor burdens in cancer patients. Stabilization of specimens is particularly desirable in protocols requiring rare cell enrichment from blood specimens drawn from cancer patients. Exposure of such specimens to potentially stressful conditions encountered, for example, in normal processing, mixing, shaking, delays due to transporting the blood, has been observed to not only diminish the number of CTC but also to generate debris and aggregates in the blood specimens that were found to interfere with accurate enumeration of target cells, if present. Stabilizers are necessary to discriminate between in vivo CTC disintegration and in vitro sample degredation.

Problems to be Solved: The present invention provides a simpler and less expensive method for purifying physiologically active proteins, especially antibodies, which can ensure removal of impurities such as DNA contaminants and viruses, and which can minimize a loss of physiologically active proteins. Means for Solving the Problems: A method for removing impurities in a physiologically active protein-containing sample, which comprises the following steps: 1) allowing the physiologically active protein-containing sample to be converted into an aqueous solution of low conductivity at a pH below the isoelectric point of the physiologically active protein; and 2) removing the resulting particles.

A system is disclosed for preventing air from entering a first catheter or cannula of a multi-catheter system. Air is prevented from entering the proximal end of the first catheter by an axially elongate chamber having an impeller, the chamber being affixed to the proximal end of the first catheter. The first catheter is affixed at an offset location, near the periphery of the chamber. The impeller is driven by a motor drive and imparts rotational energy to the fluid within the chamber forcing any air within the chamber to migrate to the center of the chamber by buoyancy effects. The air is removed through a port near the centerline of the chamber. Liquid removed with the air is returned to the chamber to minimize liquid loss during the procedure. Hemostasis valves or seals can be provided at the entrance and the exit of the chamber. A second catheter inserted through the chamber and into the first catheter is unable to entrain gas into the first catheter because any gas that enters the chamber is routed to the centerline of the chamber where it is removed. The first catheter can be a cannula or an introduction sheath, devices suited for endovascular access into the mammalian cardiovascular system where pressures may fall below ambient room pressure, a condition, which could encourage the possibility of air embolism to a patient. Inflow of fluid from an external pump scrubs the second catheter shaft of air bubbles attached by surface tension.

The present invention relates to improved methods of extinguishing fires or retarding fire propagation by forming a crosslinked water gel which is then applied to the fire or area to be protected. By forming a semi-solid crosslinked gel water can be conveyed over large distances while minimizing losses due to misting, thus making fire fighting from great distances possible and improving the efficiency of aerial drops. The crosslinked gel also has a particularly good adhesiveness and cohesiveness, giving it the ability to form one continuous blanket on the ground thereby smothering the fire and preventing re-ignition. The combination of these properties makes the crosslinked gel ideal for applications such as control and extinguishing of forest fires. In addition, the composition may include additional active ingredients such as herbicide, pesticide, fungicide fertilizer, or the like for soil remediation after the fire is extinguished.

The present invention is directed to a luminescent waveguide device, and methods of making thereof, that may be used to convert solar energy into electricity. In particular, the present invention relates to extracting and waveguiding luminescence generated in a scattering medium so as to improve luminescent concentrator performance. By stacking one or a pair of transparent plates of refractive index slightly smaller than that of luminescent plate but still larger than that of air, a much greater fraction of re-emitted light by the embedded luminescent particles can be extracted so that the detrimental effect of particle scattering can be minimized. Additionally, by additionally using a high-efficiency diffractive optic component in the structure to redirect the re-emitted photons with angles falling into the escape zone to much larger angles so these otherwise outgoing photons can be waveguided by total internal reflection. These improvements minimize the critical-angle loss and increase the output light intensity at the ends of the waveguide.
