Abstract: A non-real time RIC is configured to perform channel selection and reselection for an O-RAN to operate a CBRS network. The non-real time RIC includes a REST API interface configured to receive, from a domain proxy, operator-configured channel preference information and domain proxy time series data, and to provide a channel selection from the non-real time RIC; an R1 interface configured to receive, from an SMO database storing A1 feedback from a near-real time RIC, the A1 feedback representing channel interference over time; and an A1 interface configured to trigger, toward the near-real time RIC, a policy for channel reselection in response to the domain proxy time series data and the A1 feedback.

Abstract: Disclosed is a gNB or O-RAN for handling intermittent SA-service only failures. In some embodiments, the gNB or O-RAN are configured to detect a service outage when an NG link is down; stop broadcasting SIB1; change ssb-SubcarrierOffset (Kssb) in a MIB transmission; and change an SSB location to prevent incoming handovers from a neighbor cell.

Abstract: Message proxying among messaging systems is disclosed, including: receiving a message sent from a user of a first messaging system; associating the message with a message thread; translating the message based at least in part on a persona associated with the user; and transmitting the translated message to a second messaging system.

Abstract: A near real time RAN intelligent controller (near-RT RIC) dynamically selects an AMF for a UE by receiving over an E2 interface with a CU an AMF selection request in connection with a UE; generating, in response to the AMF selection request, an AMF selection; and sending to the CU over the E2 interface the AMF selection to cause the CU to initiate NGAP signaling with an AMF identified in the AMF selection.

Abstract: A cloud service account management method identifies unauthorized or unmanaged accounts making administration console access or API access at a cloud computing service and triggers a work flow to place the accounts under management. In one embodiment, the user device is directed to a registration portal to provide access credentials of the unauthorized account. The loud service account management method uses the access credentials to retrieve a list of account users associated with the account. Once the accounts are made managed, the cloud service account management method can monitor the activities of the account, including all of the account users, and can apply compliance or security policies to the managed accounts.

Abstract: A method of assessing a risk level of an enterprise using cloud-based services from one or more cloud service providers includes assessing provider risk scores associated with the one or more cloud service providers; assessing cloud service usage behavior and pattern of the enterprise; and generating a risk score for the enterprise based on the provider risk scores and on the cloud service usage behavior and pattern of the enterprise. The risk score is indicative of the risk of the enterprise relating to the use of the cloud-based services from the one or more cloud service providers.

Abstract: A radio node may calculate one or more performance metrics based on measured satellite signals, which are associated with a global positioning system, or wireless signals that are associated with a cellular-telephone network. Then, the radio node may determine, based on the one or more performance metrics, whether the radio node is a synchronization master in a cluster of radio nodes. When the radio node is the synchronization master, the radio node may provide information intended for a computer specifying that the radio node is the synchronization master and the one or more performance metrics. In response, the radio node may receive a synchronization request associated with another radio node in the cluster. Furthermore, the radio node may provide the synchronization information intended for the other radio node, where the synchronization information specifies time, frequency, and phase synchronization for at least the cluster.

Abstract: X-ray absorption of breast cancers and surrounding healthy tissue can be very similar, a situation that sometimes leads to missed cancers or false-positive diagnoses. To increase the accuracy of tomosynthesis and cancer diagnosis, dynamic X-ray elastography using a novel pulsed X-ray source synchronized to shear waves generated in a sample is described in the present disclosure. This imaging modality provides both absorption and mechanical properties of the imaged sample. A vibration source is used to vibrate the sample while a synchronously pulsed cold cathode X-ray source images the mechanical deformation. The generated stroboscopic images are further used to derive stiffness maps of the sample in addition to the conventional X-ray image.

The imaging system comprises an electron source configured to generate an electron beam along a first direction; an X-ray source comprising a thin film anode configured to receive the electron beam at an electron beam spot on the thin film anode, and to emit an X-ray beam substantially along the first direction from a portion of the thin film anode proximate the electron beam spot, such that the X-ray beam passes through the sample specimen. The imaging apparatus further comprises an X-ray detector configured to receive the X-ray beam that passes through the sample specimen. Some embodiments are directed to an electron source that is an electron column of a scanning electron microscope (SEM) and is configured to focus the electron beam at the electron beam spot.

Abstract: The present invention relates to a novel, non-rotating tomographic imaging system, including a multi-source x-ray imaging module which includes multiple x-ray sources within a vacuum manifold, each equipped with a non-thermionic cathode which can reduce image scan time (and hence, motion artifacts), or delivered radiation dose, through under-sampled acquisition sequences, and without adding additional sources. The non-thermionic nature of the cathode enables rapid on/off switching of x-rays without concern as to the thermal mass or the thermal time-constant of the cathode. The modules can be flexibly interconnected to each other to allow configuration as part of a distributed ring of sources, or in other x-ray imaging geometries. Modularity provides the present invention an advantage in making it easier to debug and repair a distributed-source imaging system, such as a computed tomographic (CT) system.
