Abstract: Methods, apparatus, systems and articles of manufacture to monitor media are disclosed. An example apparatus includes memory; computer readable instructions; and processor circuitry to execute the computer readable instructions to: generate a plurality of errors by comparing (a) a plurality of watermarks adjusted by offsets and (b) reference data, the adjusted watermarks corresponding to watermark data with inaccurate timing information for media; identify an offset of the offsets based on the plurality of errors; and adjust timing information of a watermark of the watermarks using the offset to increase an accuracy of the timing information.

Abstract: Antigens of Toxoplasma gondii that provide specific and strong delayed type hypersensitivity (DTH) immune response, or which stimulate IFN-? secretion, are used for testing subjects for infection. Any skin testing format may be adapted for testing for the delayed type hypersensitivity, including a patch, a needle, or a prong. Presence of DTH indicates infection. Alternate methods of detecting a T cell response including monitoring IFN-? secretion may be used.

Abstract: A fastener system for securing a component to a structure is provided. The system includes a pin portion and a clip portion. The pin portion has a head and a shaft. The clip portion has a head engagement flange and a retainer flange configured to receive a fastener that extends along a first axis. The clip portion and the pin portion are configured for engagement with one another in an engaged position, and in the engaged position the pin portion shaft extends along a second axis non-parallel to the first axis.

Abstract: The systems and methods described generally relate to evaluating vendors. The systems and methods may comprise operations performed by a computer based system comprising various components. The operations may include receiving an entity identity of a vendor, receiving a primary service category of a vendor, receiving a vendor profile comprising gathered vendor information, analyzing the gathered vendor information, determining established vendor information and additional vendor information based on the analysis, producing a vendor evaluation, and/or producing a work order.

Abstract: A cost-effective process for treating a concrete structure includes the following steps. A surface of the concrete structure is coated with an organo-silicon compound and the organo-silicon coated surface is covered so as to reduce atmospheric exposure of the organo-silicon compound while the organo-silicon compound migrates into the concrete structure.

Abstract: A method includes generating, via a dose estimator, a dose map indicative of an estimated dose deposited in a subject based on acquisition protocol parameter values of an acquisition protocol of an imaging system, and generating, via a noise estimator, at least one of a noise map indicative of an estimated image noise based on the acquisition protocol parameter values or a contrast-to-noise map based on the noise map and an attenuation map. The method further includes displaying, via a display, the dose and noise maps in a human readable format.

Abstract: A system includes a source that rotates about an examination region and emits radiation that traverses the examination region, a radiation sensitive detector array that detects radiation traversing the examination region and generates projection data indicative of the detected radiation, and a projection data de-noiser that de-noises the projection data, wherein the de-noiser de-noises a projection based on a number of detected photons for the projection.

Abstract: A method includes reducing structured artifacts in 3D volumetric image data, which is generated with reconstructed projection data produced by an imaging system (100), by processing the 3D volumetric image data along a z-axis (108) direction. The 3D volumetric image data includes structured artifacts which have high-frequency components in the z-axis direction, and lower-frequency compounds within the x-y plane.

Abstract: A method includes generating enhanced image data based on lower dose image data and a predetermined image quality threshold, wherein an image quality of the enhanced image data is substantially similar to an image quality of higher dose image data, and a system includes an image quality enhancer (128) that generates enhanced image data based on lower dose image data and a predetermined image quality threshold, wherein an image quality of the enhanced image data is substantially similar to an image quality of higher dose image data.

Abstract: An imaging system includes a radiation source (110) with an anode (202). The radiation source (110) rotates around an examination region (106) about a longitudinal axis (108) and emits radiation from a focal spot (206) on the anode (202). A source collimator (112) collimates the emitted radiation to produce a generally conically shaped radiation beam that traverses the examination region. The generally conically shaped radiation beam has an extended cone angle along the longitudinal axis that is greater than an effective maximum cone angle determined by an anode angle of the anode (202). A detector array (116) detects radiation that traverses the examination region and generates signals indicative thereof. A reconstructor (118) reconstructs the signals to generate volumetric image data indicative of the examination region.
