Abstract: Devices, systems, and methods for treating vascular defects are disclosed herein. One aspect of the present technology, for example, includes an occlusive device comprising a mesh having a low-profile state for intravascular delivery to the aneurysm and a deployed state, the mesh comprising a first end portion, a second end portion, and a length extending between the first and second end portions, and a first lateral edge, a second lateral edge, and a width extending between the first and second lateral edges. The mesh may have a predetermined shape in the deployed state in which (a) the mesh is curved along its width, (b) the mesh is curved along its length, and (c) the mesh has an undulating contour across at least a portion of one or both of its length or its width. The mesh is configured to be positioned within the aneurysm in the deployed state such that the mesh extends over the neck of the aneurysm.

Abstract: The disclosure relates to an offline-online question answering system. In some aspects, the techniques described herein relate to a method including: receiving, by a processor, a query from a user; generating, by the processor, a query embedding representing the query; identifying, by the processor, at least one question corresponding to the query by comparing the query embedding to a plurality of embeddings of questions; and transmitting, by the processor, an answer corresponding to the at least one question to the user in response to the query.

Abstract: A hub involving a large geographical area (e.g., states) communicates with other hubs and with spokes involving smaller geographical areas within the hub area. Selective hubs and spokes form a network in which they communicate messages to one another to enhance a public safety activity. A dynamic response group formed from individuals in the hub and spokes may also be included in the network. The communication between the hubs and spokes may be voluntary and may occur through Radix switches which identify the sender and the recipient, process the message and pass the processed message to the recipient. Each group or individual may be invited, or ask to be invited, into the network. Each group or individual may leave the network voluntarily or at the network's request. The groups and individuals act in the network on a coordinated basis to enhance the public safety activity.
