Resource management in a multi-modality medical system
Generally, the present disclosure is directed to managing shared resources in a multi-modality medical system. A multi-modality medical system acquires, stores, processes, and displays data associated with a plurality of different medical modalities. Although different, independent modules within the medical system handle different modality workflows, such modules rely on common resources in the system. The method and systems described herein coordinate usage of the common resources, such as a display viewport, among the independent modality modules. For example, a token-based, locking scheme is utilized to exclusively assign a shared resource to a single modality component. This locking scheme prevents, for example, resource deadlocks from occurring during a patient procedure, thus enhancing patient safety. This scheme also ensures, for example, that one diagnostic step in a patient procedure is completed before a second diagnostic step is started, and that all workflow operations halt in the event of an error. |

Artificial intelligence based stable materials discovery process
An existing materials database (EMDB) is a compilation of inorganic materials with composition and crystal structures known from prior experimental synthesis and characterization reports, or from ab initio or other computational studies, and includes a composition, structure, and stability value for each material. A hypothetical materials database (HMDB) is an extremely large compilation of materials of unknown stability and synthesizability, with no explicitly available or accessible prior experimental or computational report of their structure-composition combinations. An automated process for efficiently expanding the size of an EMDB includes a cyclical sub-process in which a rapid algorithm provides preliminary stability estimates for hypothetical materials selected from an HMDB, and those materials with a favorable stability prediction undergo a full ab initio analysis to obtain quantitative stability values and are then added to the EMDB. During each iteration of the cyclical sub-process, the rapid algorithm is trained on the EMDB, so that it becomes more effective at providing preliminary stability estimates with each iteration, as the EMDB expands. |
