Abstract: A heat transfer device, such as a heat exchanger, has dimensions and flow speed such that Reynolds number for the flow is in a range from 1 to 1000. The device uses a working fluid which is in a state of elastic turbulence. This enhances transfer of heat to or from the working fluid. In some embodiments the fluid is an emulsion with a disperse phase which changes between liquid and solid so that its latent heat of fusion contributes to the amount of heat carried by the working fluid.

Abstract: Some examples relate to locally storing a chat conversation history at an on-premises data center. As one example, a system can receive a chat message from a first client device of a first participant in a chat conversation. In response to receiving the chat message, the system can determine a data center associated with the first participant. The system can then transmit the text chat message to a server node in the data center. The server node can be configured to transmit a command to a database system of the data center. The command can be configured to cause the database system to store a copy of the text chat message in a chat log associated with the chat conversation. The system can also transmit the text chat message to a second client device of a second participant in the chat conversation.

Abstract: Described in embodiments herein are thiol-ene polymeric compositions that exhibit photo-induced, reversible switching between a solid (e.g., elastomeric) state and a liquid (e.g., flowable) state. The thiol-ene polymeric compositions may comprise a vinyl oligomer comprising at least two vinyl groups, a thiol oligomer comprising at least two thiol groups, and a Type I photoinitiator. In some embodiments, the composition comprises an excess of thiol groups relative to vinyl groups (e.g., a ratio of thiol groups to vinyl groups in the composition is at least 3:1). Reversible switching between the solid state and the liquid state may be induced through exposure of the composition to electromagnetic radiation (e.g., ultraviolet (UV) radiation). In some cases, reversible switching may be induced by a relatively low amount of energy (e.g., about 1 J/cm2 or less).

Abstract: In some embodiments, a dielectric elastomer device may include at least first and second dielectric elastomer layers, and a first layer of conductive particles disposed between the first and second dielectric elastomer layers and forming a first electrode of the device, wherein portions of the second dielectric elastomer layer are directly bonded with portions of the first dielectric elastomer layer through the first layer of the conductive particles. The dielectric elastomer layer may, for example, comprise a cured acrylic elastomer precursor with an additive including urethane, polybutadiene, or silicone. Electrodes in different layers may be interconnected by infusing a liquid or semi-liquid conductive material in contact with each of a plurality of the electrodes of the actuator or sensor device, and solidifying the conductive material to form a conductive path that interconnects the plurality of electrodes.

Abstract: A “dry” packaging in which a prosthetic heart valve is packaged within a container with hydrogel that can be provided in many forms. Certain embodiments include hydrogel that is preloaded with glycerol or the like. The hydrogel regulates the humidity within the container through a diffusion-driven mechanism if a gradient of humidity between the inside and the outside of the hydrogel exists. Humidity regulation is important to prevent the tissue of the valve structure from drying out. When the partially-hydrated hydrogel is present within container, which is saturated with air of a predefined humidity, the water molecules from the air will be absorbed by the hydrogel if the air humidity is high (i.e. when the thermodynamics favor hydrogel hydration) or vice versa. Various embodiments are configured to also house at least a portion of a delivery device for delivering the prosthetic heart valve.

Abstract: Examples herein describe techniques for communicating between data processing engines in an array of data processing engines. In one embodiment, the array is a 2D array where each of the DPEs includes one or more cores. In addition to the cores, the data processing engines can include streaming interconnects which transmit streaming data using two different modes: circuit switching and packet switching. Circuit switching establishes reserved point-to-point communication paths between endpoints in the interconnect which routes data in a deterministic manner. Packet switching, in contrast, transmits streaming data that includes headers for routing data within the interconnect in a non-deterministic manner. In one embodiment, the streaming interconnects can have one or more ports configured to perform circuit switching and one or more ports configured to perform packet switching.
