Abstract: A device may extract content, path data, and query data from API requests, and may identify events based on the extracted data. The device may combine a sequence of the events with the events to generate sequence-embedded events, and may train a neural network model with the sequence-embedded events to generate a trained neural network model. The device may receive an API request, may extract new content, new path data, and new query data from the API request, and may identify new events based on the newly extracted data. The device may process the new events, with the trained neural network model, to generate predicted events, and may calculate an anomaly score based on the predicted events. The device may compare the anomaly score with a threshold to determine a risk for the API request, and may cause the API request to be blocked or permitted based on the risk.

Abstract: A lens module with enhanced absorption of stray light includes a sensor and a mounting bracket. The sensor includes a photosensitive area and a non-photosensitive area arranged surrounding the photosensitive area. The sensor is received in the mounting bracket and a window is defined in the mounting bracket. An annular flange extends from an inner wall of the window towards a center axis of the window. The annular flange includes a reflecting surface facing away from the inner wall of the window and tilted towards the sensor.

Abstract: During calibration of a SPECT system, system-specific sensitivities and cross-calibration factors for multiple isotopes for correcting for dose are determined for various combinations of options, including the option of which specific well counter with which to measure the dose. The options may include selected energy windows for isotopes with multiple energy windows. This arrangement allows for custom-specified isotopes not included in standard listings. For use with a particular patient, the cross-calibration factor for the well counter used to measure the dosage for the patient is accessed and used for dose correction. More accurate quantitative functional information may result from the corrected dose. The cross-calibration may be more easily implemented despite the options using the sensitivities and cross-calibrations provided for various combinations.

Abstract: Systems and methods are provided for determining an access request provided by an entity that seeks to interact with one or more backend systems through a middleware system, the access request including a genuine access token. The entity can be authenticated based on the genuine access token. When a client request is made to the middleware system with a genuine access token, the request can be made through a smart ingress and egress proxy which intercepts the request and replaces the genuine access token with an invalid access token. The middleware system can subsequently make authorized requests to downstream systems on behalf of the middleware system's client by treating the smart proxy as an egress proxy for those subsequent requests, and the smart proxy replaces the invalid access token with a genuine one.

An example method generally includes receiving a training data set including images in a first category and images in a second category. A convolutional neural network (CNN) is trained using the training data set, and a feature map is generated from layers of the CNN based on features of images in the training data set. A first area in the feature map including images in the first category and a second area in the feature map where images in the first category overlap with images in the second category are identified. The first category is split into a first subcategory corresponding to the first area and a second subcategory corresponding to the second area.
