Abstract: Disclosed is a stroke-based differentiable rendering for both representation of spatiotemporal sensor data and unsupervised spatiotemporal events detection wherein we encode DAS waterfall data into a structured latent space based on parameterized brushstrokes. The structured brushstroke representation can (1) suppress background noise and distracting clutters from the original waterfall data, (2) allow easy leverage of geometrical prior knowledge for physics-informed pattern recognition. Guided by multiple specially designed targets that emphasize different aspects of the original data, the optimized strokes not only preserve the salient information, but also align well with the original data in terms of spatial and temporal coordinates. As a results, it also provides pixel-level annotation as a byproduct. Based on long term DFOS data and cumulative statistics, we can further localize landmarks (such as traffic lights, manholes, etc.) from the waterfall data. These landmarks can be used for cable mapping.

Abstract: An image to be processed is acquired. At least one candidate pixel on the target to be tracked is determined based on a current pixel on a target to be tracked in the image to be processed. An evaluated value of the at least one candidate pixel is acquired based on the current pixel, the at least one candidate pixel, and a preset true value of the target to be tracked. A next pixel of the current pixel is acquired by performing tracking on the current pixel according to the evaluated value of the at least one candidate pixel.

Abstract: A test system for a managed cloud computing environment may have a management system that may recruit devices in the cloud and outside the cloud to perform a test on a cloud based application. Each device may execute an agent that connects the device to several cloud services for messaging, data collection, and executable code storage. The management system may identify and gather the devices, then cause the devices to execute a test by sending commands through the messaging service. The devices may access executable code for the specific tasks of a test through the code storage service, and as the devices complete tasks for the test, the devices may publish results in the data collection service. The test system enables any type of scenario to be implemented, including operations that can only be performed inside and outside the managed cloud environment.

Abstract: Methods of treating lung diseases comprising administering inducers of NAD(P)H:quinone oxidoreductase 1 (NQO1) are disclosed. Inducers of NQO1 include naphthoquinones such as ?-lapachone. Methods of predicting whether a subject with a lung disease will respond to treatment with a naphthoquinone are also described herein.
