Method for dynamic information technology infrastructure provisioning
Provisioning and management resources are drawn from an overall pool of resources. Management and managed resources are then dynamically associated on the network to securely perform requested on-demand management functions. Since the managing system controls the networking between the devices that are managed or provisioned, the linkage of resources incurs a minimal amount of network overhead. Since provisioning resources are themselves dynamically built and automatically associated with the resources being managed, a dramatically reduced management overhead is achieved. |

Decision feedback channel estimation and pilot tracking for OFDM systems
Current OFDM systems use a limited number of symbols and/or sub-channels to provide approximations for channel estimations and pilot tracking, i.e. phase estimations. For example, two training symbols in the preamble of a data packet are used to provide channel estimation. Four of the fifty-four sub-channels are reserved for providing phase estimation. However, noise and other imperfections can cause errors in both of these estimations, thereby degrading system performance.Advantageously, decision feedback mechanisms can be provided to significantly improve channel estimation and pilot tracking in OFDM systems. The decision feedback mechanisms can use data symbols in the data packet to improve channel estimation as well as data sub-channels to improve pilot tracking. |

Movable body system, pattern formation apparatus, exposure apparatus and exposure method, and device manufacturing method
A laser beam emitted by an encoder main body enters a wafer table via a PBS from the outside, and reaches a grating at a point that is located right under exposure area, and is diffracted by the grating. Then, by receiving interference light of a first polarized component that has returned from the grating and a second polarized component reflected by the PBS, positional information of the wafer table is measured. Accordingly, because the first polarized component, which has passed through PBS passes through the wafer table until it is synthesized with the second polarized component again, does not proceed through the atmosphere outside, position measurement of the wafer table can be performed with high precision without the measurement beam being affected by the fluctuation of the atmosphere around the wafer table. |

The selection of the surface coating acts not only as an anti-blocking agent, or partitioning aid to keep the tacky polymer particles separated, but also provides the suspended polymer particle with a density that matches the carrier. This prevents separation of the slurry components over time. Such materials, ultimately used as pipeline additives to reduce the fluid drag and increase the volumetric throughput, can be stored and shipped for extended periods of time without degradation of the slurry quality. Upon injection into the pipeline, the polymer particle dissolves quickly, unhindered by the coating. |

Drilling fluid containing chlorosulfonated alpha-olefin copolymers
This invention is based upon the finding that certain chlorosulfonated α-olefin copolymers can be beneficially utilized in drilling fluids that are utilized in drilling subterreanean wells. For instance, it has been unexpectedly found that certain chlorosulfonated α-olefin copolymers can be beneficially used as total or partial replacements for organoclays in oil based drilling fluids. The chlorosulfonated a-olefin copolymers that are useful in the practice of this invention are typically chlorosulfonated ethylene/octene copolymers or chlorosulfonated ethylene/butene copolymers. The utilization of chlorosulfonated α-olefin copolymers in oil-based drilling fluids offers (1) long service life at high operating temperatures, (2) minimal formation damage, (3) improved filtration behavior, and (4) highly effective performance at low viscosifier levels. Additionally, the chlorosulfonated α-olefin copolymers utilized in the practice of this invention are soluble in conventional drilling fluid formulations which reduce the level of mixing required in preparation of the drilling fluid formulation.

In one embodiment, the method enables accurate volume dispensation calculations independent of meniscus shape. In another embodiment, the method enables accurate determination of plate washing efficiency. In yet another embodiment, the method enables the accurate determination of dilution ratio over a plurality of dilution steps. The methods described may be carried out using one or more systems arranged to perform the steps. A kit of the invention includes instructions for carrying out the steps of the methods and, optionally, one or more solutions suitable for conducting photometric measurements. |

Systems and methods for localizing and analyzing samples on a bio-sensor chip
Chips that include one or more particle manipulation mechanisms, or force transduction elements, provided at specific locations to manipulate and localize particles proximal the substrate surface. In one embodiment, individually addressable magnetic control mechanisms such as electric coils are provided at specific locations to create a magnetic field to attract magnetic particles, such a magnetic or magnetizable beads, to those specific locations. In another embodiment, electrostatic control mechanisms such as electrodes are provided to attract and manipulate electrically charged micro-particles. A location may include a crater or well formed in the substrate, or it may include an element on the surface of the substrate. In some embodiments, one or more sensors are located proximal specific locations, e.g., specific craters, so as to analyze specific conditions at each location. In other embodiments, multiple locations share one or more sensors. |

Panel of biomarkers for peripheral arterial disease
The invention provides biomarkers including β-2-microglobulin, Cystatin C, hsCRP and glucose as well as methods for using the biomarkers for diagnosing and/or assessing the risk of peripheral artery disease in a subject. In some embodiments, the subject being tested may be suffering from or at risk of other circulatory diseases, including coronary artery disease. Hemoglobin A1c or other proxies for measuring glucose levels may be substituted for or measured in addition to glucose in the context of the present invention. |
