摘要:
A photoacoustic transducer, such as a photoacoustic probe includes an optical fiber, diaphragm, at the optical fiber, whereby the optical fiber and diaphragm define a cavity, and an energy absorption film at the optical fiber, whereby an activating laser directed through the optical fiber can excite the energy absorption film to thereby generate an acoustic wave that, upon reflection upon a remote surface, can deflect the diaphragm and modify reflection of a detecting laser also directed through the optical fiber. A method of detecting an acoustic wave includes directing an activating laser through an optical fiber to an energy absorption film at the optical fiber, directing a detecting laser through the optical fiber and cavity to the diaphragm at the optical fiber, and measuring an interference pattern generated at least in part by reflection of the detecting laser from a surface of the diaphragm.

An optical fiber sensor (100) can be used to measure pressure with high sensitivity and fine resolution. As a (108) at the end of the sensor expands or contracts, the spectrum of a beam reflected from the end of fiber shifts, producing a change linked to pressure exerted on the sensor. Novel aspects of the present inventive sensor include the direct bonding of a silica thin film diaphragm (110) to the optical fiber with localized or confined heating and a uniform thickness of the diaphragm. The resulting sensor has a diameter that matches the diameter of the optical fiber. Because the sensor is all silica, it does not from temperature-induced error. In addition, the sensor can be very sensitive because the diaphragm can be very thin; it can also make highly repeatable measurements due to its very uniform thickness.

Polyamidoamine, its partially degraded products or its complexes-Math1 gene nanoparticles, method for preparing the same and use thereof, the gene nanoparticles can be produced through complex coacervating of polyamidoamine, or polyamidoamine complexes and a Math1 gene-containing plasmid. The gene nanoparticles are controllable in particle size, uniform in size, favorable for surface modification, can enhance the ability of expression and delivery of the Math1 gene, and is useful in a sensorineural hearing loss caused by hair cells loss due to noise, drug toxicity etc.
摘要:
According to one embodiment, a method includes receiving data regarding a plurality of licenses. Each license is associated with one or more respective software products. The data is partitioned such that first and second licenses of the plurality of licenses are grouped together. The first and second licenses are each associated with at least a first software product of the one or more respective software products. A first group identification is assigned to the first and second licenses.
摘要:
According to one embodiment, a method for determining license compliance includes receiving data regarding a plurality of licenses, including at least first and second licenses. The first license has a corresponding first license count that applies to a first software product. The second license has a corresponding second license count that applies to the first software product. An instance count of the first software product is determined. A determination is made regarding whether the instance count can be apportioned to the first and second licenses, such that neither the first or second license counts are exceeded.
