Abstract: A non-transitory computer-readable storage medium including instructions for distributing tasks between a handheld intermediary processing device (HIPD) and communicatively coupled devices is disclosed. The instructions cause one or more processors to, while a HIPD and a head-wearable device are communicatively coupled and share operational data for performing one or more computational tasks, identify one or more back-end tasks and one or more front-end tasks associated with performing the one or more computational tasks. The instructions further cause performance of the one or more back-end tasks at the HIPD including updating the operational data to create updated operational data. The instructions further cause performance of the one or more front-end tasks at the head-wearable device using the updated operational data such that a representation based on the one or more computational tasks is presented to the user by the head-wearable device.

Abstract: Methods of producing plutonium-238 are disclosed. One method includes dissolving neptunium-237 in a nitric acid solution to produce a neptunium target solution, subjecting the neptunium target solution to neutron radiation to produce plutonium-238, and removing the plutonium-238 from the neptunium target solution. A second method includes exposing a solution of neptunium-237 to neutron radiation to produce plutonium-238, complexing the plutonium-238 with an organophosphorus compound, and separating the plutonium-238/organophosphorus compound complex from the solution of neptunium-237. A third method includes dissolving neptunium-237 to form a neptunium-237 target solution, exposing the neptunium-237 to thermal neutrons to produce plutonium-238, utilizing an organophosphorus compound to complex the plutonium-238 and the organophosphorus compound, extracting the plutonium-238/organophosphorus compound complex from the irradiated neptunium target solution, and recovering the plutonium-238.
