Abstract:
A method of processing a positron emission tomography (PET) imaging data set (30) acquired of a subject includes independently localizing each positron-electron annihilation event of the PET imaging data set based on time of flight (TOF) localization of the positron-electron annihilation event to form a generated image (34). The generated image may be displayed. The generated image is suitably used as the basis for an initial image of an iterative reconstruction (40) of the PET imaging data set (30) to produce a reconstructed image (42). A spatial contour (56) of an image of the subject in the PET imaging data set (30) is suitably delineated based on the generated image (34). A subject attenuation map (62) for use in PET image reconstruction (40) is suitably constructed based in part on the spatial contour (56).

Abstract:
A torque detecting system for a bottom bracket axle of a power-assisted bicycle includes a torque sensor for being mounted on the bottom bracket axle of the bicycle, a wireless signal transmitter arranged stationarily relative to the bottom bracket axle, and a wireless signal receiver for being arranged at a location of a bicycle frame of the bicycle in proximity to the bottom bracket axle. The wireless signal transmitter is adapted for receiving a detected signal, which is outputted from the torque sensor, and then transmitting the detected signal to the wireless signal receiver wirelessly. In this way, the signal attenuation and the possibility of signal loss of the detected signal can be minimized during the signal transmission, such that the torque applied on the bottom bracket axle by the bicyclist can be detected precisely.

Processes for catalytically synthesizing ethylbenzene from ethanol and benzene comprising: 1) reacting a first mixture comprising ethanol and benzene with at least one catalyst chosen from binder-containing alkylation catalysts and binder-free alkylation catalysts in an alkylation reactor to obtain a second mixture comprising residual benzene, ethylbenzene, diethylbenzene, and water; 2) passing the second mixture successively through a benzene recovery tower, an ethylbenzene recovery tower, and a polyethylbenzene recovery tower to obtain separated water, separated benzene, separated ethylbenzene, and separated diethylbenzene; and 3) reacting a third mixture with at least one transalkylation catalyst in a transalkylation reactor, wherein the third mixture comprises at least some of the separated benzene and at least some of the separated diethylbenzene at a weight ratio ranging from about 2:1 to about 10:1.
Abstract:
A spectrum shaping scheme for chirped pulse amplification (CPA): uses a spectrum decomposing system with CTSI construction, a spectrum synthesizing system with CTSI structure that is symmetrical to the decomposing structure, and a spectrum shaping system including an aperture and a planar reflector for spectrum shaping function design. The scheme includes the following steps: firstly decomposing the spectrum of a chirped temporal pulse laser to a spectral domain; then shaping the spectrum in the spectral domain; finally synthesizing un-shiftily this shaped spectrum in the spectral domain into a temporal chirped pulse with a designed shape. The scheme has the benefit that it can be not only utilized in a general laser spectrum shaping and spectrum modulation, but also can be utilized for a high energy and ultra-high peak-power laser system in chirped pulse amplification with a large caliber and with a chirped pulse bandwidth of a few nanometers.

Abstract:
High-throughput methods are provided for quantitatively measuring the modulation of heat shock protein (HSP) expression in a cell by exposing the cell to at least one stress and measuring cellular stress responses. High-throughput methods for identifying modulators (activators or inhibitors) of HSP or HSF expression in a cell by treating the cell with an agent, such as a compound or composition, exposing the cell to a stress, and measuring responses of the cell to the stress in the presence or absence of the agent are also provided. Devices useful in performing high-throughput methods of the invention, and modulators identified using such methods, are also provided.
Abstract:
A system and method of determining at least one location for a retail outlet in a region are described. The system and method use clustering technology for partitioning the region into a fixed number of sub-regions. Then, the system and method compute marginal increments from input data for each sub-region. The system and method choose a sub-region having a maximal marginal increment for a location of a first retail outlet.
Abstract:
A method for determining a total benefit derived from a subset of products in a product portfolio includes identifying a set of customer orders having a set of ordered products from the product portfolio and an order benefit and selecting the subset of products from the product portfolio. The method also totals the order benefits from the set of customer orders whose set of ordered products are included within the subset of products from the product portfolio. An apparatus is provided for use in determining a total benefit derived from a subset of products in a product portfolio.
Abstract:
Sorting data using a multi-core processing system is disclosed. An unsorted data set is copied from a global memory device to a shared memory device. The global memory device can store data sets for the multi-core processing system. The shared memory device can store unsorted data sets for sorting. The unsorted data set can include a plurality of data elements. The unsorted data set can be sorted into sorted data in parallel on the shared memory device using a cluster of processors of the multi-core processing system. The cluster of processors may include at least as many processors as a number of the data elements in the unsorted data set. The sorted data can be copied from the shared memory device to the global memory device.
