Abstract: A method of determining a decoupling matrix of a decoupling system for an array of coils of a parallel transmission magnetic resonance imaging (MRI) system includes obtaining impedance matrix data for the array of coils without the decoupling system, determining, based on the impedance matrix data for the array of coils, an objective function representative of deviation from a decoupled operating condition for the array of coils in which the array of coils are decoupled via the decoupling system, and defining, with a processor, a decoupling matrix representative of a set of impedances of the decoupling system with an iterative procedure that optimizes elements of the decoupling matrix to minimize the objective function and reach the decoupled operating condition.

Abstract: A data storage unit of a data editing apparatus stores both a base indicating a data attribute and a data value in association with each other as data to be edited. A code acquisition unit acquires a user code, which is a code described in a first program language for describing data editing details by intensive notation and which describes editing details for the data to be edited that are based on the base. A code generation unit generates, in accordance with a predetermined correspondence relationship between a second program language for describing data editing details by extensive notation and the first program language, an execution code described in the second program language based on the user code. An editing processing unit edits the data to be edited in accordance with the execution code.

Abstract: A method, apparatus, and article of manufacture for irradiating one or more targets within a sample with electromagnetic (EM) radiation. One or more targets within the sample are controllably defined with an acoustic field. The sample is irradiated with input EM radiation having an input wavefront. An amount of frequency shifted EM radiation is detected, wherein at least some of the input EM radiation that passes through the acoustic field at the targets is shifted in frequency to form the frequency shifted EM radiation. The input wavefront is modified, using feedback comprising the amount of the frequency shifted EM radiation that is detected, into a modified wavefront. The sample is irradiated using the input EM radiation comprising the modified wavefront, and the process is repeated as desired.

Abstract: In a radio network having a plurality of first users on channel (FUOCs) and one or more second users on channel (SUOCs), a method and apparatus for a SUOC to select a channel to co-occupy based upon a “selfish” goal of achieving a desired SUOC rate and an “altruistic” goal of causing low-impact on the FUOC. A SUOC collects signal parameters for a plurality of FUOCs, orders the FUOCs based upon different criteria, and attempts to co-exist with FUOCs until a suitable FUOC channel is found.
Abstract: Apparatus, system and method for medical analysis of a seated individual, includes determining the aortic valve opening; the PTT; and calculating the PWV. Determining the aortic valve opening includes collecting BCG data while sitting on a seat and determining the timing of the aortic valve opening, taking into account posture. Measuring the aortic pulse wave transit time includes collecting BCG data while sitting on a seat capable of measuring changes in apparent weight; determining the timing of the aortic valve opening; detecting the arrival of the pulse wave at the end point; and measuring the relative timings of the two events. Calculating the PWV includes determining a length of the arterial segment through which a pulse wave is to be measured between a start point and an end point; and dividing the determined length of the arterial segment by the PTT.

Abstract: Bipolar wave current, with both positive and negative current portions, is used to electrodeposit a nanocrystalline grain size deposit. Polarity Ratio is the ratio of the absolute value of the time integrated amplitude of negative polarity current and positive polarity current. Grain size can be precisely controlled in alloys of two or more chemical components, at least one of which is a metal, and at least one of which is most electro-active. Typically, although not always, the amount of the more electro-active material is preferentially lessened in the deposit during times of negative current. The deposit also exhibits superior macroscopic quality, being relatively crack and void free.
