Abstract: To search for digital twins (avatars) on a computerized platform, a semantic embedding is made of the search query and this is compared with respective semantic embeddings generated for digital twins on the computerized platform, to determine a first set digital twins whose semantic embeddings are similar to that of the search query. A trained graph neural network generates respective graph embeddings of feature data of the first set of digital twins, and these graph embeddings are compared with graph embeddings that the trained graph neural network generates for other digital twins on the platform, to determine a second set of digital twins whose graph embeddings are similar to graph embeddings of the first set of digital twins. The search results returned in response to the search query may include at least one digital twin in the second set of digital twins.

Abstract: A spray-capillary device is configured to process ultra-low-volume samples. The spray-capillary device includes a capillary tube that includes a lumen, an inner surface, an outer surface, an inlet end for receiving a fluid, and a discharge end having a porous section. A polymer material may be applied to the inner surface to form a polymer coating thereon. A downstream connector provides an interface between the porous section of the capillary tube, a conductive fluid, and a high voltage electrical source. The application of voltage to the downstream connector causes electrospray ionization, which can be used to draw ultra-low-volume samples into the inlet end. A gas injection assembly can be used to increase the pressure on the inlet end of the capillary tube to encourage movement of the sample therethrough. The spray-capillary device may be used to provide the ultra-low-volume samples to a mass spectrometer or other suitable analytic device.
