Silicon photomultiplier array-based multispectral optical probes for image-guided radiotherapy
Cerenkov Emission (CE) during external beam radiation therapy (EBRT) from a linear accelerator (Linac) has been demonstrated as a useful tool for radiotherapy quality assurance and potentially other applications for online tracking of tumors during treatment. However, an overlooked area is the molecular probing of the cancer status during delivery mainly due to the limited detection sensitivity of CE and lack of flexible tools to fit into an already complex treatment delivery environment. Silicon photomultiplier (SiPM) can be used for low light detection due to their extreme sensitivity that mirrors photomultiplier tubes and yet has a form factor that is similar to silicon photodiodes, allowing for improved flexibility in device design. This work assesses the feasibility of using SiPMs to detect CE, interrogate the tumor molecular status during EBRT, and contrast its performance with silicon photodiodes (PDs) available commercially. |

Real time multi-tenant workload tracking and auto throttling
Technologies are disclosed for real-time workload tracking and throttling within a multi-tenant service. Multi-tenant services receive requests from computing devices associated with different tenants. While processing requests, the multi-tenant service itself sends requests to an underlying resource, such as a database. Requests from computing device associated with an overactive tenant may cause the multi-tenant service to overwhelm the underlying resource. The overwhelmed underlying resource may not know which tenant a request received by the underlying resource is associated with, and so the underlying resource is unable to only throttle requests originating from computing devices associated with the overactive tenant. Instead, the underlying resource throttles all requests from the multi-tenant service. To avoid this result, the multi-tenant service tracks utilization of the underling resource associated with each tenant, and throttles requests received from overactive tenants before the underlying resource becomes overwhelmed and throttles all requests from the multi-tenant service. |

Detecting and preventing password leakage using a device-level network filter
A user name, password and associated domain are stored for each account managed by a password manager on a computing device. A device-level network extension filters network traffic. Passwords are identified in outbound network traffic. Target domains to which identified passwords are being transmitted are compared to stored domains associated with the identified passwords.
