Abstract: An anonymous computerized trading system matches orders by conducting auctions at specified times. As well as entering orders, participants assign credit limits for the duration of the auction, thus minimizing the time for which credit is allocated to the system.

Abstract: A method for image correction in a mobile X-ray device includes obtaining an X-ray image corresponding to a region of interest, where the X-ray image includes a projection of the region of interest by an X-ray beam on a detector plane. The method further includes receiving a tilt parameter corresponding to the detector plane. Moreover, the method includes generating a corrected X-ray image based on the X-ray image and the tilt parameter using a perspective projection technique, where the corrected X-ray image corresponds to a projection of the region of interest on a corrected detector plane.

Abstract: A novel thermoacidophilic pullulanase (Tk-PUL) from hyperthermophilic archaeon Thermococcus kodakaraensis KOD1 is described here that efficiently hydrolyzes starch under industrial conditions in the absence of any additional metal ions. The gene encoding Tk-PUL was cloned and expressed in E. coli cells. The purified recombinant enzyme possesses the following properties: shows both pullulanase and ?-amylase activities, displays highest activity at 95-100° C., active over a broad pH range (3.0-8.5) with optimum working pH 3.5, stable for several hours at 90° C. and displays a half-life of 45 minutes at 100° C., activity and stability are independent of calcium and other metal ions, and hydrolyzes maltotriose. Moreover, recombinant Tk-PUL can be used for single step liquefaction and saccharification of corn starch (without any ?-amylase or ?-amylase) at pH 4.2 in the absence of calcium.

Abstract: Benchmarks for the price of a financial instrument such as FX spot rate for a currency pair are calculated by an algorithm based on a previous benchmark and a market price. The market price is derived from a deal price and a quote price. The deal price is based on deals conducted since the last benchmark and the quote price is based on bids and offers entered since the last benchmark. For each of the deal and quote prices, a price, weight and scatter is calculated which is used to calculate a benchmark price, weight and scatter and a benchmark error.

Abstract: An optical displacement sensor is provided according to one embodiment. The optical displacement sensor comprises a housing; a displacement member coupled to the housing, configured to contact an object under test and move based on displacement of the object under test; a light emitter coupled to the housing; an optical transducer coupled to the housing; and a reflecting surface coupled to the displacement member to reflect at least a part of the light emitted from the light emitter to the optical transducer, such that movement of the displacement member modifies intensity distribution of the light reflected to the optical transducer.

Abstract: Methods and apparatus for optimizing wireless communications channels by employing multi-channel modulation techniques in wireless communication systems is disclosed. The wireless communications channel may comprise tones, and data may be allocated differently among the different tones according to the channel characterization measurements. In one embodiment, a method may include: transmitting data over a wireless channel using a first station (e.g., an access point), receiving the data using a second station, performing calculations on the received data, and allocating subsequent data transmissions among the tones according to the calculations. Other embodiments may utilize superfluous data transmissions—for example, data coming from the access point that is intended for other stations—in order to calculate channel characterization. Preferably, any portion of the transmitted data (e.g., preamble, header, data, etc.) may be used to calculate channel characterization.

Abstract: A system and method of relay code design and factor graph decoding using a forward and a backward decoding scheme. The backward decoding scheme exploits the idea of the analytical decode-and-forward coding protocol and hence has good performance when the relay node is located relatively close to the source node. The forward decoding scheme exploits the idea of the analytical estimate-and-forward protocol and hence has good performance when the relay node is located relatively far from the source node. The optimal decoding factor graph is first broken into partial factor graphs and then solved iteratively using either the forward or backward decoding schemes.
