The use of time-lapsed NMR diffusivity measurements in an observation well is disclosed. The observation well is cased in the zone of interest with non-magnetic and non-conductive casing that is invisible to the NMR tool. Second, because NMR measurements have a dead zone in front of the antenna depending on the spatial variation of the fixed magnet strength, for example about 2.7 inches, a distance between the casing and the formation is reduced to less than the dead zone length by drilling the observation well at small deviation of about 5° and running the casing without centralizers. Both the casing and the pad-type NMR tool will follow the low side of the borehole, ensuring the measurement volume of the NMR tool is inside the formation and beyond the annulus. With the appropriate observation well completion, time-lapse diffusivity measurements with pad-type NMR tools can address several shortcomings in the current practice of monitoring EOR processes that rely upon changes in density and hydrogen index (HI). Various uses of NMR imaging in wells cased with non-metallic casing are also disclosed.

Systems, methods, and graphical user interfaces are provided for identifying, analyzing, and adopting opportunities for optimizing clinical processes within clinical facilities. An optimized practice process model may be defined for a particular clinical procedure, setting forth an optimal clinical process. In addition, critical levers may be identified within the optimal clinical process, representing the activities that have the greatest impact on outcomes. Clinical facilities may collect current measures for the critical levers, and the current measures may be compared against an optimal, benchmark, and / or target measure. Based on the comparison, opportunities for clinical process optimization may be identified. Those opportunities may then be analyzed and prioritized for adoption into a facility's current practice. Clinical processes within healthcare facilities may be further improved by continuously monitoring facility data and identifying further opportunities of optimization. Further, collected data may be used to refine the optimized practice process model, allowing for further optimization.

This invention provides for an improved method for differentially diagnosing ACTH-dependent Cushing's syndrome. Current practice for differentially diagnosing ectopic ACTH syndrome and Cushing's Disease measures relative ACTH concentrations from the inferior petrosal venous sinus compared to fluid obtained from a periphery venous sample. This is performed before and after administration of exogenous corticotropin releasing factor, or after administration of metyrapone. This invention uses glucocorticoid receptor antagonists to induce release of endogenous CRH which stimulates ACTH to increase in patients with ectopic ACTH syndrome but not in those with Cushing's Disease.

Current practice of the common source configuration is to connect the sources of the two discrete MOSFETs (housed either in separated packages or in a single package) externally on the printed circuit board. Because the gate pads and source pads of the two dies are alternatively placed between gate and source, it does not allow the sources of the power MOSFETs to be connected internally, which requires an additional layer of circuit board to connect the sources and the gates externally. This invention provides a novel electronic device layout design and a novel packaging technique for common source configuration, placing two MOSFETs in a package with their sources connected to a single source post which is located between tow gate posts. In order to facilitate gate bonding and to prevent any shorting between gate and source, two gate pads are used and placed at the upper adjacent corners of each MOSFET.

In the MPEG2 Advanced Audio Coder (AAC) standard, Temporal Noise Shaping (TNS) is currently implemented by defining one filter for a given frequency band, and then switching to another filter for the adjacent frequency band when the signal structure in the adjacent band is different than the one in the previous band. The AAC standard limits the number of filters used to either one filter for a “short” block or three filters for a “long” block. In cases where the need for additional filters is present but the limit of permissible filters has been reached, the remaining frequency spectra are simply not covered by TNS. This current practice is not an effective way of deploying TNS filters for most audio signals. We propose two solutions to deploy TNS filters in order to get the entire spectrum of the signal into TNS. The first method involves a filter bridging technique and complies with the current AAC standard. The second method involves a filter clustering technique. Although the second method is both more efficient and accurate in capturing the temporal structure of the time signal, it is not AAC standard compliant. Thus, a new syntax for packing filter information derived using the second method for transmission to a receiver is also outlined.

A system and method for optimally managing the inventory of railroad freight cars and for transporting and processing the unladen cars to reloading points. The system provides a means for returning unladen cars at one or more strategically located yards or aggregation facilities where the cars are cleaned, inspected, repaired / maintained, stored and blocked for ultimate delivery. After such processes the cars may be treated as generic, and used for the transport of any materials within the constraints of the car type, rather than being dedicated to specific products and returned to a specific production facilities as in current practice. As well, the method provides a means by which multiple car operators may pool their collective rail car assets to further optimize the rail car supply chain. The method provides a means to determine candidate locations for such aggregation facilities / processing yards, and for optimal inventory control, sorting by next destination, and transit scheduling to deliver unladen cars to their next reloading points. The system and method are particularly useful in transporting specific polymer resins to a manufacturing region and returning the rail car through the aggregation / processing facility such that the cleaned, repaired, inspected, stored and blocked car may be used at any resin production facility.

A thermal oxidation tester is shown for determining thermal stability of a fluid, particularly hydrocarbons when subjected to elevated temperatures. The tendency of the heated fluid to oxidize and (1) form deposits on a surface of a heater tube and (2) form solids therein, are both measured at a given flow rate, temperature and time. The measured results are used to determine whether a fluid sample passes or fails the test. Sample flow rate is important in the jet fuel thermal oxidation test. Current practice requires manual drop counting or flow confirmation with the use of volumetric glassware. An apparatus is described to precisely measure the flow rate and automatically perform flow rate check using a drip rate method and / or volumetric method.
