Abstract: Chemical propellant storage and supply systems and methods for use on spacecraft are provided. The systems and methods include a fluid pump for moving chemical propellant within the system at selected pressures. This can include operating the fluid pump to supply propellant to a thruster system at a selected pressure. A fuel tank can be refilled by connecting a propellant resupply source to the system, and operating the fluid pump to move propellant from the propellant resupply source to the fuel tank. In a system with multiple fuel tanks, the fluid pump can be operated to move propellant from a donor fuel tank to a recipient fuel tank. The chemical propellant can be stored in one or more fuel tanks at a relatively low pressure. In addition, the chemical propellant is not pressurized by a gaseous pressurant while it is stored in the fuel tank.

Abstract: Spacecraft propulsion systems and methods featuring a first storage tank containing a metallic propellant and a second storage tank containing a non-metallic propellant are provided. A selected one of the metallic propellant and the non-metallic propellant is supplied to an electric propulsion thruster, depending on an operational mode of the spacecraft. The metallic propellant is stored at a relatively high density, while the non-metallic propellant is stored at a lower density than the metallic propellant. Moreover, the non-metallic propellant is preferably utilized to produce thrust through the electric propulsion thruster during operational maneuvers, while the metallic propellant is reserved for producing thrust through the electric propulsion thruster during end-of-life, such as deorbiting, maneuvers.

Abstract: A protocol has been developed for genetically engineering an attenuated pathogen such as the influenza virus that can grow in cells without interferons but has suppressed growth in cells with the interferons. The protocol comprises systematically identifying immune evasion functions on the pathogen's genome, then eliminating the immune evasion functions while maintaining a certain replication fitness of the pathogen. The resulting attenuated pathogen causes a strong immunologic response and can be used in a live attenuated vaccine.

Abstract: Instruction generation for a data processing array and microcontroller includes generating a tensor-level intermediate representation from a machine learning model using kernel expressions. Statements of the tensor-level intermediate representation are partitioned into a first set of statements and a second set of statements. From the first set of statements, kernel instructions are generated based on a reconfigurable neural engine model. The kernel instructions are executable by a compute tile of a data processing array to implement compute functions of the machine learning model. From the set of second statements, microcontroller instructions are generated based on a super-graph model. The microcontroller instructions are executable by a microcontroller of the data processing array to move data into and out from the data processing array.

Physical pens can be structured to impede a direct flow of the first medium into a second medium in the pens while allowing diffusive mixing of the first medium and the second medium. Virtual pens can allow a common flow of medium to multiple ones of the pens.

Abstract: Hardware acceleration of machine learning (ML) designs includes translating an ML primitive into an intermediate representation. The intermediate representation is subdivided to specify a functional compute block. The functional compute block is sized according to a compute node primitive adapted for implementing the ML primitive on target hardware. An overlay is generated for the ML primitive, at least in part, by mapping the functional compute block to the compute node primitive. The overlay is synthesizable to implement the ML primitive on the target hardware. The overlay can be scheduled for operation within the target hardware as part of an ML design including the ML primitive.
