Abstract: A method of printing a cellular solid by direct bubble writing comprises introducing an ink formulation comprising a polymerizable monomer and a gas into a nozzle, which includes a core flow channel radially surrounded by an outer flow channel. The ink formulation is directed into the outer flow channel and the gas is directed into the core flow channel. The ink formulation and the gas are ejected out of the nozzle as a stream of bubbles, where each bubble includes a core comprising the gas and a liquid shell overlying the core that comprises the ink formulation. After ejection, the polymerizable monomer is polymerized to form a solid polymeric shell from the liquid shell, and the bubbles are deposited on a substrate moving relative to the nozzle. Thus, a polymeric cellular solid having a predetermined geometry is printed.

Abstract: Techniques are described for enabling users to configure the auto scaling of virtual computing resources using various intent-based auto scaling configurations. Intent-based configurations generally provide various indications of how a user intends to use a scalable group of virtual computing resources and what expectations a user might have about how those resources are scaled in response to changes in demand. A service provider network receives first input to create a scalable group of virtualized computing resources, the first input indicating at least one primary scaling configuration used by the hardware virtualization service to scale the scalable group of compute instances over time, and further receives second input indicating at least one secondary, intent-based scaling configuration used to scale the virtualized computing resources, for example, when the service is unable to scale the group of virtualized computing resources according to the at least one primary scaling condition.

Abstract: A tamper evident primary container (20) for storing and/or transporting valuables, particularly currency and other documents comprises an envelope (14) with tamper evident features and a partition for dividing the envelope into first (30) and second portions (32) that communicate with each other through at least one path. A first opening (22) in the envelope is provided through which articles can be inserted into the first portion and a seal for sealing the first opening is provided. A second opening (36) opens into the second portion through which a staining medium can be introduced into the second portion when desired. The path is constructed and arranged so as at least to inhibit access to the first portion through the second portion and to indicate tampering if access is breached. The partition is intermittent to form a plurality of paths that can permit a staining medium to be dispensed into the first portion through the second portion.
