Abstract: Disclosed are hierarchical buoyant materials comprising porous components having multiple length scales that provide reduced density, higher strength, and improved buoyancy. The hierarchical buoyant materials include components having at least two length scales including a first porous material having elements characterized by a first linear length scale and a second porous material having elements characterized by a second linear length scale. The first porous material includes hollow microspheres, and the second porous material provides low effective density via geometrical arrangements. The second linear length scale is substantially different than the first linear length scale in terms of size, e.g., diameter, length, or distance.

Abstract: A cluster of network flows is formed on the basis of a particular entity-to-entity relationship, and individual network flows within the cluster are further identified on an application-by-application basis to better characterize communications between two compute instances connected through a data network. By individually scoring network flows for each application with a variety of tools, and aggregating these individual scores into a composite score for the cluster of network flows, more accurate threat detections can be supported based on an increase in relevant threat data and a more complete view of risk factors.

Abstract: A heat and humidity exchanger comprises panels made up of membrane sheets attached on either side of a separator. Channels extend across each panel between the separator and the membrane sheets. The panels are much stiffer than the membrane sheets. Panels are stacked in a spaced apart relationship to provide an ERV core. Spacing between adjacent panels may be smaller than a thickness of the panels.

Abstract: Disclosed herein is a system and method of controlling a strander by wireless visual monitoring. In certain embodiments, a stranding system includes at least one vision device mounted to a rotating structure of a strander. The at least one vision device is configured to capture a view of at least a portion of a subunit reel of at least one of a set of payoff units of the rotating structure to generate vision data. The stranding system further includes at least one wireless communication module mounted to the rotating structure to receive and wirelessly transmit the vision data over a high-bandwidth data link. The stranding system is configured to proactively identify payout hazards of the subunit package (e.g., cable crossover) to, for example, prevent damage to the strander.

Abstract: Aspects of the invention include computer-implemented methods, systems, and computer program products that assign a centralized event tag to each communication interface of a plurality of communication interfaces of a chip interconnected in a hierarchy through the communication interfaces to a plurality of chips in a multiprocessing system. A determination is performed of whether to accept or drop a message associated with an event received at one of the communication interfaces of the chip based on comparing a local centralized event tag with a received centralized event tag. The local centralized event tag is updated based on one or more advancing rules to maintain event synchronization between the chip and the plurality of chips.

Abstract: A process of preparing a compounded hydrostable poly(aliphatic ester-carbonate) includes providing a hydrostable poly(aliphatic ester-carbonate), compounding in an extruder the hydrostable poly(aliphatic ester-carbonate) and 0.05 wt % to 0.60 wt % of a multifunctional epoxide compounding stabilizer, based on the total weight of the compounded hydrostable poly(aliphatic ester-carbonate), under vacuum of 17000 to 85000 Pascals, and a torque of 30% to 75%, to provide the compounded hydrostable poly(aliphatic ester-carbonate). After compounding, at least one of the following apply: the inter-sample variability in molecular weight is less than 5%, wherein inter-sample variability is determined by comparing five 100 mil chips of the compounded hydrostable poly(aliphatic ester-carbonate); the % weight average molecular weight (MW) difference is less than 5% after hydroaging at 85° C.

Abstract: An example method comprises receiving, at a first digital device, video data, scanning video content of the video data for visual transitions within the video content between consecutive frames of the video data, each transition indicating significant visual transitions relative to other frames of the video data, timestamping each visual transition and create a first set of temporal video fingerprints, identifying items of metadata to be associated with the video data, identifying a location within the video data using the temporal video fingerprints for the identified items of metadata, generating a metadata index identifying each item of metadata and a location for each item of metadata relative to the video data using at least one of the temporal video fingerprints, and transmitting, at the first digital device, the video data, the first set of temporal video fingerprints, and the metadata index to a different digital device.

Abstract: A sandwiching device for creating pocket sandwich-type food, the sandwiching device having a punch, a die to work with the punch to cut foodstuff, and a sealer seated within the die to seal the foodstuff while being cut with the punch and die. The punch can be lowered to press against the die and the sealer. When the foodstuff is placed on the die, pressing the punch against the die and the sealer simultaneously cuts the crust off the foodstuff while sealing the edges to create a pocket sandwich. To facilitate the sealing, the perimeter edge of the sealer may have a scalloped edge.
