Abstract: The current document is directed to graph databases and, in particular, to improvements in the operational efficiencies of, and the range of functionalities provided by, graph databases. One currently disclosed improvement provides for associating user-defined and developer-defined functions with node and relationship entities stored within the graph database. These entity-associated functions are executed in entity-associated execution environments provided to the entities during query execution. Another currently disclosed improvement provides text-replacement-based preprocessing of graph-database queries for increased clarity and for increasing the speed and accuracy with which the queries can be formulated.

Abstract: A compact, mask-mountable powered air purifying respirator (“PAPR”) includes a housing and an impeller driven by a motor to draw air in through an inlet in the housing and direct the air to an outlet at an opposite end of the housing. The impeller comprises S-shaped fan blades that direct the air radially outward from the bottom of the impeller. The radial airflow meets S-shaped fins on a flow straightener that redirect the airflow downward through the PAPR housing outlet. The fan blades and flow straightener drive the airflow directly and efficiently, without unnecessary travel of air through the PAPR assembly, thus providing an improved airflow efficiency.

Abstract: Systems, methods, and computer program products are provided for directing cash flows associated with a mortgage-backed security to back other securities without collapsing the original mortgage-backed security. A mortgage-backed security/an/or a set of loans is analyzed to identify cash flows from mortgages having specific desirable characteristics, and the cash flows are directed to subgroups or pools that support new mortgage-backed securities. The new securities make the desirable cash flows available to an issuer or prospective investor without collapsing the original mortgage-backed security.

Abstract: A filter includes a filter outer wall, and a filter inner wall spaced apart from the filter outer wall. The filter inner wall and the filter outer wall define a filter void therebetween, and the filter inner wall and the filter outer wall extend along a filter axis. A volume of filtration material is positioned in the filter void, and a plurality of baffles extend between the filter inner wall and the filter outer wall. The plurality of baffles are configured to induce a helical component to an airflow entering the filter void at a first void end relative to the filter axis and exiting the filter void at a second void end opposite the first void end.

Abstract: A predictive map is obtained by an agricultural material application system. The predictive map maps predictive weed values at different geographic locations in a field. A geographic position sensor detects a geographic locations of an agricultural material application machine at the field. A control system generates a control signal to control the agricultural material application machine based on the geographic locations of the agricultural material application machine and the predictive map.

Abstract: A method of inhibiting dry material clogs in a work vehicle having an air boom assembly includes moving the work vehicle at a vehicle speed along a ground surface, moving dry material from a holding tank onto a conveyor, and operating the conveyor at a conveyor speed, the conveyor speed being at least partially dependent upon the vehicle speed, moving material from the conveyor into a boom assembly with a blower, dispensing the dry material onto the ground surface through a plurality of nozzles of the boom assembly, and comparing the conveyor speed to a maximum acceptable conveyor speed. If the conveyor speed is greater than the maximum acceptable conveyor speed, the method includes performing at least one of the following: alerting the operator that the conveyor speed is greater than the maximum acceptable speed, and reducing the vehicle speed to thereby reduce the speed of the conveyor.

Abstract: Disclosed is an integrated respiratory and eye protective system that is light-weight and easily carried, is fast and easy to apply by a user, and that ensures protection of a user against inhalation or ingestion of or exposure to environmental contaminants, including for example dangerous aerosolized chemical, biological, and radiological materials. The system includes a mask that fits tightly over a user's nose and mouth and down and around their neck, with two filter assemblies on either side of the mask that filter environmental contaminants out of the air as the user breathes in through the mask. Goggles are provided that provide a single, continuous seal against the user's face and about the user's eyes, with the bottom, central portion of the goggles configured to engage and closely mate with the top, central portion of the mask.

Abstract: Systems and methods for measuring plant leaf gas exchange based on instantaneous mass balance in the sample chamber. The response of leaf net assimilation rate (Anet) to computed leaf internal CO2 concentration (C1) is measured by continuously varying the input CO2 concentration and measuring the continuous difference between chamber input (reference) and output (sample) concentrations to compute a continuous series of Anet values, which can then be plotted against computed Ci. When combined with a similar response test using an empty chamber test to allow for sample chamber mixing and/or gas analyzer match dynamics and/or small flow-related residual time delays, such method provides accurate and rapid A Ci response (RACiR) curves in a much shorter time than conventional methods.
