Abstract: Embodiments are directed to techniques for chaining, triggering, and/or enforcing entitlements in a constrained environment. A constrained environment may be provided within with shielded assets are required to exist or execute. An entitlement may be granted on a variety of shielded assets, including datasets, computations scripts, data privacy pipelines, and intermediate datasets generated by an intermediate step of a data privacy pipeline. Thus, a beneficiary may use a granted entitlement as an input into other data privacy pipelines, without the need for the grantor to approve each specific downstream operation. The constrained environment may enforce an entitlement by fulfilling applicable constraints upon accessing the entitlement, restricting the output of the entitlement to the constrained environment, and fulfilling applicable policies when executing downstream operations.

Abstract: Disclosed are systems and methods for connecting a hydraulic fracturing fluid source to various wells at a given well site. In general, use of disclosed systems and methods provide for repositioning (refocusing) the hydraulic fracturing operation amongst multiple wells may be achieved. In one example, a system to reroute fracturing fluid from a source to various wells at a well site may be provided. The use of adapters and quick clamp connections allow hydraulic fracturing fluid to be rerouted between various wells in a manner to decrease the cost and reduce hazards associated with changing hydraulic fracturing locations. Modular components of the system (and an overall modular design of the system itself) may allow a centralized manifold to be relocated to various locations at one or more well sites.

Abstract: One example method includes providing temporary access to a computing system and to providing temporary access as a service. The features of a temporary access can be defined by an entity and a user may be able to obtain a token that includes these features, which may be embedded in the token as claims. The user's access is then controlled in accordance with the embedded claims. The temporary access as a service can be federated. The token may include trust levels and tolerance limits. Further, aspects of the temporary access can be monitored and/or changed. Adjustments to trust levels can be automated or manually performed. Further trust for specific users can be gained or lost over time based on at least previous accesses.

Abstract: An energy-promoting composition includes an exogenous ketone body component that provides a source of caloric energy, a vasodilator component, a stimulant component, such as caffeine, and optionally a nootropic component. In most if not all cases, the vasodilator, stimulant, and nootropic components do not themselves provide a source of caloric energy but may increase metabolism of available caloric energy. The separate components beneficially and synergistically interact with one another to enhance the overall energy-promoting effect of the composition more rapidly and to a greater degree than if one or more of the components are omitted. The energy-promoting composition is also formulated to minimize the crash effect common to stimulants such as energy drinks.
