As a PUF device ages, the response characteristics of the device change. Thus, mappings made on the original PUF outputs can drift and become invalid. Re-enrollment or re-mapping of hidden values to PUF response characteristics can resolve the changing nature of the PUF. Unfortunately, an adversary may tamper with the PUF during re-enrollment compromising security of the PUF. Accordingly, techniques of securely and remotely re-enrolling a PUF device are described. During an initial enrollment of the PUF device, multiple sets of enrollment values of the PUF device can be generated. For remote re-enrollment, a first initial set of enrollment values can be used to authenticate the PUF device. Upon authentication using the first initial set, the PUF device can re-enroll the PUF device and account for changes in PUF characteristics. A second set of initial enrollment values can then be used to verify that the PUF device is unaltered.

Resource management techniques, such as cache optimization, are employed to organize resources within caches such that the most requested content (e.g., the most popular content) is more readily available. A service provider utilizes content expiration data as indicative of resource popularity. As resources are requested, the resources propagate through a cache server hierarchy associated with the service provider. More frequently requested resources are maintained at edge cache servers based on shorter expiration data that is reset with each repeated request. Less frequently requested resources are maintained at higher levels of a cache server hierarchy based on longer expiration data associated with cache servers higher on the hierarchy.

The invention relates to a system and a method for haptic interaction with virtual objects. The system of the invention is based on the idea that, for the haptic representation of any virtual three-dimensional object—synchronized with the visual representation—only the tangible haptic characteristics of the surface area of the object at the collision point or the area of contact are important. The haptic display system (morphling) of the invention that displays these characteristics comprises in principle three functional groups, which operate in synchronism with one another and with a visual subsystem. The individual subsystems can be operated statically or dynamically. In dynamic operation, users can change the position and/or shape, for example, of the tactile display by touching it.With regard to the real-time representation of the three-dimensional data of the user, at least the body part that is interacting with the object, e.g. the hand, must be represented in the visual system; the body part may also be directly visible, as with a head-up display. Ideally, all body parts of the user that lie within the user's field of view are displayed visually. With the synchronized real-time combination in the visual subsystem, users and objects that are actually spatially separated are displayed virtually in a defined spatial proximity. In this virtual representation, the user thus sees himself touching the virtual object. At the time of collision and at the collision point, however, he does not actually interact with the object represented in the visual system, but with a haptic display subsystem, the morphling, in a tactile subsystem which, in the tangible portion of the virtual object, displays the object's haptic characteristics, e.g. its surface condition and shape, synchronized in real time with the visual representation.The interaction between the at least one body part of the visualized user and the visualized object are represented in the visual subsystem simultaneously with the interaction of the user with the tactile display system, and upon collision of the at least one part of the visualized user with the visualized object, a collision point is determined. The three-dimensional data of the object at the collision point of the at least one part of the visualized user with the visualized object are presented in the tactile subsystem, the haptic element having a surface with structuring that is designed such that the haptic element displays the three-dimensional structure of the object at the collision point based on the captured three-dimensional data of the object, at least in the area of the collision point.

This invention generally relates to a composition and method of using recombinant microRNAs (miRNA) and their hairpin-like precursors (pre-miRNA) as therapeutic drugs for treating Alzheimer's diseases (AD). More specifically, the present invention relates to the use of man-made miRNA miR-302 precursors (pre-miR-302) for AD therapy in humans. These pre-miR-302 molecules can be mass produced in prokaryotes as a form of DNA expression-competent DNA vectors and/or hairpin-like RNAs. As prokaryotic cells do not transcribe or process hairpin-like RNAs, the present invention also teaches a method for expressing pre-miRNAs in prokaryotes, i.e. pro-miRNA, using a novel hairpin-like RNA transcription mechanism newly found in prokaryotes. Additionally, since miR-302 is a well-known embryonic stem cell (ESC)-specific factor in humans, our novel findings of this invention can be further used to advance the designs and development of novel regenerative medicine for treating many other ageing-related degenerative diseases, such as Parkinson's diseases, osteoporosis, diabetes, and cancers.

Embodiments described herein relate generally to the large scale production of functionalized graphene. In some embodiments, a method for producing functionalized graphene includes combining a crystalline graphite with a first electrolyte solution that includes at least one of a metal hydroxide salt, an oxidizer, and a surfactant. The crystalline graphite is then milled in the presence of the first electrolyte solution for a first time period to produce a thinned intermediate material. The thinned intermediate material is combined with a second electrolyte solution that includes a strong oxidizer and at least one of a metal hydroxide salt, a weak oxidizer, and a surfactant. The thinned intermediate material is then milled in the presence of the second electrolyte solution for a second time period to produce functionalized graphene.

A radiator funnel assembly facilitates filling refrigerant liquids in different radiators. The assembly provides various sizes and types of adapters and caps, with each adapter and cap having a unique identifier to facilitate assemblage and indicate a matching radiator fill opening. The assembly includes a funnel configured to receive a radiator fluid and carries the radiator fluid through a spout. Multiple conduits detachably attach in series to the spout. Multiple adapters receive the conduits and engage a specific radiator fill opening. Each adapter has a unique identifier that enables identification of the connecting conduit, and also identifies the specific type of radiator fill opening that is operable with the adapter. Multiple caps fasten the adapters to the radiator opening. Each cap has a unique identifier to identify and match to the appropriate adapter. This is useful for matching the adapter and cap to different types of radiators.

A composite bottle opener includes: a cork remover unit having a hand grip, a bottle stopper and a corkscrew, one end of which is connected to the hand grip while the hand grip is attached detachably on the bottle stopper; a retractable fixing sleeve including an upper sleeve mounted movably on a lower sleeve while the cork removes unit is mounted on the upper sleeve; and one compressible cutter unit installed on a side wall of the lower sleeve such that the cutter is movable in a thickness direction of the side wall of the lower sleeve. In use, one needs to apply a little torque to tear away the sealing foil around the outer periphery of the bottle as well as the cork blocking the mouth of the bottle. The bottle stopper can be plugged back into the mouth of the bottle after the cork removal.
