    摘要: A loudspeaker system composed of a flexible panel with an affixed array of force actuators, a signal processing system, and interface electronic circuits is described. The system described is capable of creating a pattern of standing bending waves at any location on the panel and the instantaneous amplitude, velocity, or acceleration of the standing waves can be controlled by an audio signal to create localized acoustic sources at the selected locations in the plane of the panel.

    摘要: Provided herein is a transgenic animal whose genome comprises a first nucleic acid sequence encoding a fusion polypeptide, wherein the fusion polypeptide comprises a Cre recombinase and a mutated ligand binding domain of human estrogen receptor (CreER), wherein the first nucleic acid is operably linked to a chondrocyte-specific promoter and a second nucleic acid sequence encoding a β-catenin polypeptide, wherein the second nucleic acid sequence comprises one or more loxP sequences. Also provided is a method of modifying a transgenic animal comprising administering tamoxifen to the transgenic animal. Also provided are methods of screening for an agent that reduces or prevents Cre-Negative Control one or more symptoms of osteoarthritis or intervertebral disc disease in a subject. Methods for identifying a subject with or at risk of developing osteoarthritis or intervertebral disc disease are also provided, as well as methods of treating or preventing osteoarthritis or intervertebral disc disease in a subject.
