Abstract: Described herein are techniques of using machine learning to automatically extract clinical variable values for subjects from clinical record data. The techniques designate certain clinical variables as hybrid variables that can be assigned values by machine learning model prediction. The techniques process, using a machine learning model trained to predict a value of a hybrid variable, clinical record data associated with a subject to obtain a predicted hybrid variable value and an associated confidence score. The techniques set the value of the hybrid variable for the subject to the predicted hybrid variable value when the model prediction is of sufficiently high confidence.

Abstract: An integrated sampling probe, valve and vaporiser (16) for a liquefied natural gas container is provided which comprises a vaporiser body (24) having a vaporisation chamber (66), a fluid inlet (40) in communication with the vaporisation chamber (66), a fluid outlet (58), and a vaporised-fluid flow path extending from the vaporisation chamber (66) to the fluid outlet (58). The fluid inlet (40) is formed as a critical orifice dimensioned to enable vaporisation of fluid passing into the vaporisation chamber (66), and there is a valve member (63) which is drivable to open and close the critical orifice, along with a heating assembly (50) for heating the valve member (63) to enable vaporisation of fluid passing through the critical orifice and into the vaporisation chamber (66). A sampling probe body (18) is also provided extending from the vaporiser body (24), the sampling probe body (18) having a sampling bore (36) which is in fluid communication with the fluid inlet (40).

Abstract: An Application Rendering Platform (“ARP”) is described. The platform facilitates application rendering, which is the ability of a single application to manifest multiple application behavior sets. The ARP may include Application Rendering Server and a client component, for example a Client Rendering Software. The Client Rendering Software is an Application designed such that its overall behavior, including its user interface components and its functionality, can be controlled dynamically by the Application Rendering Server component. A user (“owner”) can access the ARP configure a unique Behavior Set to be manifested for their Registrants (“end users”) alone. Such a Behavior Set includes, but is not limited to, such qualities as the application badge, the user interface, color scheme, the feature menu contents, the functionality set, the graphical imaging and layout and the feature naming and language used.

Abstract: A sampling device comprises a mounting body connectable to a fluid container for housing a fluid requiring sampling. The mounting body has a fluid-sample flow passage opening into a connector recess; a sample-tube connector engaged with the connector recess; and a sample tube which extends from a distal end of the sample-tube connector and tightly engages with the fluid-sample flow passage. A cavity thus defined by the connector recess and the distal end of the sample-tube connector is bridged by the sample tube. The bridging prevents or limits contamination of a fluid sample extracted from a fluid flow in a fluid container to which the device is attached.
