摘要:
According to one embodiment of the present invention, a method for integrating client and server deduplication systems may be provided. In this method, a first hash set of a previous backup session may be received from a server. The first hash set may comprise a plurality of cryptographic values generated using a plurality of data blocks of a first data set of a client. A second hash set may be generated using a plurality of data blocks of a second data set of the client. A deduplicated data set may be generated by the client according to the first hash set and the second hash set and may comprise a plurality of non-redundant data blocks of the second data set. The second hash set and the deduplicated data set may be transmitted to the server.

A biocompatible insulin delivery device is provided comprising an insulin reservoir sealed with a glucose-responsive plug or membrane. The plug functions to release insulin from the reservoir in response to a hyperglycemic glucose concentration and to prevent insulin release from the reservoir in response to hypoglycemic glucose concentration. In one embodiment, the plug is made of a biocompatible polymeric matrix comprising an inorganic component, a stimulus-responsive component and a catalytic component.

This invention provides water-swellable articles and hydrogels that contain a hydrophilic polymer and perfluorocyclobutane crosslinking segments. The perfluorocyclobutane crosslinking segments are covalently attached to the polymeric chains of the hydrophilic polymer so that the crosslinking segments chemically link the polymeric chains to each other. The present invention also provides a method of making a crosslinked hydrogel by first attaching one or more substituted aromatic trifluorovinyl or aromatic trifluorovinyl ether moieties to a hydrophilic polymer to form a modified polymer and then heating the modified polymer at an elevated temperature to form perfluorocyclobutane segments from the trifluorovinyl or trifluorovinyl ether moieties. These water-swellable articles and hydrogels may be used in biomedical and pharmaceutical applications and may be suitable for implanted joint repair materials such as an articulating or bearing surface in a hip, knee, spine, finger, ankle, elbow, wrist, or shoulder joint.

A secret string is established so as to be known only to a client computing system and a server computing system. A non-encrypted version of a message, a message counter value, and first hash value are received by the server computing system from the client computing system. The first hash value, based on a content of the message, the message counter value, and the secret string, is generated at the client computing system using a first hash algorithm. Using the first hash algorithm, the server generates second hash value based on the content of the received message, the received message counter value, and the secret string. The server computing system accepts the received non-encrypted version of the message as authentic upon determining that the received message counter value is greater than a previously received message counter value and that the second hash value matches the first hash value.
摘要:
The invention provides a multi-polymer hydrogel article having a first polymeric, water-swellable material and a second polymeric material, organized such that a first region substantially comprises the first polymeric, water-swellable material, a second region adjacent the first region comprises a mixture of the first polymeric, water-swellable material and the second polymeric material, and a third region adjacent the second region substantially comprises the second polymeric material. The article exhibits an increasing concentration gradient of the second polymeric material moving from the first region, through the second region, to the third region. The invention also provides methods for forming a multi-polymer hydrogel article by (a) forming a hydrogel structure using a first polymeric, water-swellable material, (b) creating an aerogel structure having a plurality of open pores by dehydrating the hydrogel structure, (c) contacting the aerogel structure with a second polymeric material to incorporate the second polymeric material into at least a portion of the plurality of open pores to form the multi-polymer hydrogel article, and (d) rehydrating the multi-polymer hydrogel article.

A video encoder that utilizes adaptive interpolation filtering for coding video data includes a prediction unit, a reconstruction unit, a reference picture buffer, a filter parameter estimator for estimating filter parameters according to the original video data and the predicted samples, and an adaptive interpolation filter for utilizing the stored filter parameters to perform filtering on the reconstructed video data.
摘要:
A dual-hook locking assembly mounted in a casing subassembly is actuated from outside of the latter by a handle which causes a locking subassembly to operate between an unlocked and a locked position. By rotating the driving handle, a gearing subassembly including a pair of meshed segmental gears drives the locking subassembly between the aforementioned positions. The gearing subassembly and the locking subassembly are directly interconnected. An adjusting subassembly is used for positioning the locking subassembly with respect to a strike plate of a door. The adjusting subassembly comprises several guiding plates. The latter and the gearing subassembly have a common center of rotation.
摘要:
A green algal extract that contains astaxanthin at a concentration of 8 wt % or more can be obtained by cultivating an encysted green alga in a nutrient medium while supplying carbon dioxide and providing irradiation with light at a photosynthetically active photon flux input of 8000 μmol-photon/m3/s or more, and extracting an oil component, which contains astaxanthin. A green alga that belongs to the genus Haematococcus is preferable.
