Abstract: Data processing/GUIs for NFT block chain data to “tell the story” of ownership or highlight “cool” aspects of a computer game-related NFT in simplified way. Machine learning (ML) may be used to boil down the complexity of data to what people need or want to understand. The displayed timeline of ownership as presented in a GUI can be interactive. Types of metadata to encapsulate in the NFT are discussed.

Abstract: A target material supply apparatus includes: first and second fluid flow components (1122, 1126) that define an axial flow path when joined together, in which the axial flow path is between a source of target material fluid and a nozzle supply apparatus; and a coupling apparatus configured to seal the joint between the first and second fluid flow components. The coupling apparatus includes a gasket (1105) having an annular shape defining an inner opening that is a part of the axial flow path when seated and sealed. When the gasket is seated between the first and second fluid flow components to thereby seal the joint formed by attaching the first and second fluid flow components, pressure applied to the gasket from target material fluid traversing the gasket inner opening along the axial flow path improves the hermetic function of the seal at the joint. Optionally, a functional insert like e.g. a flow restrictor (1160) can be seated in the gasket.

Abstract: An isolated protein comprising a mutant soluble activin II receptor (ActRIIA or ActRIIB) extracellular domain (Ac-tRIIA-ECD or ActRIIB-ECD), wherein said mutant soluble ActRIIA-ECD or ActRIIB-ECD comprises a mutation to remove the N-linked glycosylation site corresponding to position N18 of SEQ ID NO: 1.
