摘要:
Provided are a method, system, computer storage device, and storage area network for maintaining a communication path from a host to a storage subsystem in a network. A storage subsystem controls data transfer and access to a storage devices in a network, wherein the storage subsystem is coupled to a switch and the switch is coupled to a host in the network. A topological storage is coupled to the host, the switch and the storage subsystem, for storing a topological coupling relationship between the host and the switch and a topological coupling relationship between the switch and the storage subsystem. In response to determining a failed path between the storage subsystem and the switch coupled to the storage subsystem, the storage subsystem determines a first port on the storage subsystem in the failed path. The storage subsystem determines from the topology storage the topological coupling relationship between the host and the switch and the topological coupling relationship between the switch and the storage subsystem. The storage subsystem redirects, based on the topological coupling relationships, a message sent to the first port of the storage subsystem to an operational second port in the storage subsystem coupled to the switch.

Systems and methods of sorting electronic color images of objects are provided. One method includes receiving an input representation of an object, the representation including pixels defined in a first color space, converting the input image into a second color space, determining a query feature vector including multiple parameters associated with color of the input representation, the query feature vector parameters including at least a first parameter of the first color space and at least a first parameter of the second color space and comparing the query feature vector to multiple candidate feature vectors. Each candidate feature vector includes multiple parameters associated with color of multiple stored candidate images, the candidate feature vector parameters including at least the first parameter from the first color space and at least the first parameter from the second color space. The method further includes determining at least one of the candidate images to be a possible match to the desired object based on the comparison.

Aspects of the present invention describe soft imprint lithography methods capable of preparing structural features on surfaces. Disclosed methods include surmounting a deformable substrate, having an original form, with a composition, wherein the deformable substrate is capable of achieving at least one predetermined deformed state; predictably deforming said deformable substrate from its original form to the at least one predetermined deformed state; and transferring at least a portion of the composition surmounting the deformed substrate to a receiving substrate.

Provided are thermo-responsive polymersomes, which display cold-controlled encapsulation near the physiological temperatures, and have a PDI less than 1.2. Morphology of the thermo-responsive polymersomes is a function of the weight fraction of the hydrophilic block in the block copolymer and the number average molecular weight (Mn) of the block copolymer. When the lower critical solution temperature (LCST) is at, or slightly above physiological temperature, the thermo-responsive block displays hydrophobic properties, such that the block copolymer self-assembles in aqueous solution to form a polymersome with the thermo-responsive block occupying the core of the polymersome and the hydrophilic block occupying the corona of the polymersome. Below the LCST, the thermo-responsive block displays hydrophilic properties, such that the polymersome dissociates, providing fast release of an active agent encapsulated therein.

Reversibly adaptive rough structures, comprising: a substrate; a plurality of raised elements on the substrate, the raised elements mutually spaced apart by channel regions on the substrate, each of the raised elements having a lateral surface and a distal end; the lateral surface, the distal end and the channel regions having hydrophobic molecules thereon; and the distal end having reversibly adaptive bristles thereon, the reversibly adaptive bristles being convertible between relatively hydrophilic and hydrophobic states by the application of an external stimulus. Techniques for making reversibly adaptive rough structures.
摘要:
A method and apparatus is disclosed wherein nanostructures or microstructures are disposed on a surface of a body (such as a submersible vehicle) that is adapted to move through a fluid, such as water. The nanostructures or microstructures are disposed on the surface in a way such that the contact between the surface and the fluid is reduced and, correspondingly, the friction between the surface and the fluid is reduced. In an illustrative embodiment, the surface is a surface on a submarine or other submersible vehicle (such as a torpedo). Illustratively, electrowetting principles are used to cause the fluid to at least partially penetrate the nanostructures or microstructures on the surface of the body in order to selectively create greater friction in a desired location of the surface. Such penetration may be used, for example, to create drag that alters the direction or speed of travel of the body.
