Abstract: Methods for forming vascular components include providing a composite sacrificial body comprising a first sacrificial material having an outer surface and a second sacrificial material applied to at least a portion of the outer surface, molding a solid substrate around the composite sacrificial body, removing the first sacrificial material by deflagration such that at least a portion of the second sacrificial material remains in the same orientation relative to the substrate as originally molded, and subsequently removing the second sacrificial material by a non-deflagration process to form a vascular component. The second sacrificial material can include a phase change material, a syntactic foam including hollow beads bound together with a polymeric binder or a sintered aggregation of hollow beads, a polymeric foam, a water-soluble resin, or an aerogel. The non-deflagration process can include mechanical pulverization, contacting the second sacrificial material with a solvent or chemical etching agent.

Abstract: A locking system securing an image scanning device to a container includes a compressible material. The compressible material is disposed between a first securing plate and a second securing plate. A rotational element is disposed within curved edges of the first and second securing plates, where the curved edges each curve away from the compressible material. A shaft extends from the rotational element to the image scanning device. A fastener is secured through the first and second securing plates, and into the securing surface to lock the rotational element, and subsequently the shaft and image scanning device, in place. The locking system can be secured to a pitched surface to naturally position the image scanning device perpendicular to level ground.

Abstract: Techniques for address mirroring of a file system journal are presented. A transactional file system update can correspond to a write operation to be performed at a first participant node of a data storage system. A journal transfer component can transfer the transactional file system update from an initiator node of the data storage system to a first journal associated with the first participant node and recovery information relating to the update to a second journal associated with a second participant node of the data storage system. The recovery information can be determined based on the update. To facilitate the update, a journal descriptor block can be generated and sent to the second participant node, such block comprising the recovery information, which can include transaction state, block addresses involved in the transaction, error correction-related information, or a mirror block address set for the block addresses where desired.

Abstract: A foldable extension enclosure for a utility enclosure, each having first, second, third, and fourth sides connected by hinges and each folding only in one direction by means of detents on the sides. A first end of the first side slidably overlaps a second opposite end of the third side and a first end of the second side slidably overlaps a second opposite end of the fourth side. There is an internal top ledge on each side in an interior near a top end of the extension enclosure and the utility enclosure and an external bottom ledge on each side on an exterior near a bottom end of the extension enclosure, to mount the extension enclosure to the utility enclosure with concave and convex detents. Convex detents are at the top end of the utility and extension enclosures and concave detents are at the bottom end of the extension enclosure. The convex detents also reversibly lock a lid to the tops of the utility and extension enclosures.

Abstract: Systems and methods are provided for determining the quality of a civic address produced by a reverse geocoder, utilizing the uncertainty of a geodetic location and a distance between the geodetic location and a geocoded location (i.e., a civic address) determined by the reverse geocoder. Upon receiving a request by a PSAP for a civic address corresponding to a UE initiating a call for emergency services, a node initially identifies a geodetic location of the UE and an uncertainty of the geodetic location. The node initiates an API call to a reverse geocoder API. The node receives a geocoded location corresponding to the geodetic location and compares the geocoded location to the geodetic location to determine a distance between them. Based on the uncertainty of the geodetic location and the distance between the geodetic location and the geocoded location, a quality of the civic address is determined.

Abstract: Methods of controlling a tandem axle assembly in a vehicle, the tandem axle assembly including an inter-axle differential (IAD), one or more side gears, and a front tandem axle assembly having a pair of front tandem axle half shafts selectively connected to a pair of front tandem axle wheel hub assemblies. When a determined speed of the vehicle is greater or equal to a predetermined speed, the IAD may be locked, the tandem axle wheel hub assemblies may be disconnected from their respective tandem axle shafts, and/or the IAD may be moved out of engagement with the one or more side gears. When a determined speed of the vehicle is less than a predetermined speed, the IAD may be unlocked, the tandem axle wheel hub assemblies may be connected to their respective tandem axle shafts, and/or the IAD may be engaged with the one or more side gears.

Abstract: An electrical power converter can include a plurality of layers disposed on a substrate. An emitter, including a first semiconductor junction that is formed at an interface between a first pair of adjacent layers, can produce light in response to a first electrical signal. An absorber, including a second semiconductor junction that is formed at an interface between a second pair of adjacent layers, can absorb at least some of the light. Circuitry can produce a second electrical signal in response to the absorbed light. The second electrical signal can be substantially proportional to the first electrical signal and can be electrically isolated from the first electrical signal. Because the light can remain within the layers during use, the electrical power converter can have a higher efficiency than a comparable device that propagates the light through at least one interface between air and a semiconductor material.

Abstract: Four genes, A622, NBB1, PMT, and QPT, can be influenced for increasing nicotinic alkaloid levels in Nicotiana plants, as well as for synthesizing nicotinic alkaloids in non-nicotine producing plants and cells. In particular, overexpressing one or more of A622, NBB1, PMT, and QPT may be used to increase nicotine and nicotinic alkaloid levels in tobacco plants. Non-nicotine producing cells can be engineered to produce nicotine and related compounds by overexpressing A622 and NBB1.
