Abstract: The present disclosure provides a generative modeling framework for generating highly realistic and privacy preserving synthetic records for heterogenous time-series data, such as electronic health record data, financial data, etc. The generative modeling framework is based on a two-stage model that includes sequential encoder-decoder networks and generative adversarial networks (GANs).

Abstract: A neutron detector includes an anode and a cathode. The cathode circumscribes the anode and has a plurality of planar segments facing the anode. In one embodiment, the neutron detector is part of an array of neutron detectors.

Abstract: A 10B neutron detector and an associated method of detecting neutrons. The detector includes an exterior shell bounding and sealing an interior volume, a neutron-sensitive boron coating located on at least part of the exterior shell at the interior volume. One of the boron coating and the exterior shell serves as a cathode, and a central structure located within the interior volume and serves as an anode. The detector includes gas within the interior volume that conducts an electrical energy pulse between the cathode and the anode in response to a neutron impinging upon the neutron-sensitive boron coating. The gas includes a quantity of 3He gas sensitive to neutron impingement and generating an electrical energy pulse for reception by the anode in response to a neutron impinging upon the 3He gas. The method includes detecting at least one neutron via impingement of the neutron upon the 3He gas.

Abstract: A neutron detector array that includes a hollow member circumscribing an axis and bounding a volume. A divider extends parallel to the axis within the hollow member to divide the volume into a plurality of volume portions. A plurality of anodes extend parallel to the axis; at least one anode within each volume portion. A plurality of cathodes wherein the hollow member has an interior surface and the divider has surfaces that are coated with neutron sensitive material. Also, a neutron detector that includes a hollow cathode bounding a volume portion with at least a partial wedge cross-section, and an anode extending thought the volume portion. An electric field exists during operation of the neutron detector within the volume portion, the electric field varying across the cross-section, and the anode being located at an area of maximum field strength within the field. The detector may be used in the array.

Abstract: A sensing element or detector activated by radiation comprising a first scintillator activated by gamma radiation; and a neutron sensing layer comprising a second scintillator activated by neutron radiation.

Abstract: The gamma-radiation module includes a housing having a box-like container and a cover for hermetically sealing a pair of cylinders within the housing. Each cylinder includes scintillation material and a photomultiplier tube on a common cylindrical axis. The hermetically sealed module may be used singly or in multiple modules in portal applications whereby gamma-radiation from a source may be detected through a gamma-radiation transparent cover on the module.
