20140025113 | COMPOSITE SPINAL FACET IMPLANT WITH TEXTURED SURFACES - Implementations described and claimed herein provide a distal leading portion of a composite spinal implant for implantation in a spinal facet joint. In one implementation, the distal leading portion includes a distal leading end, a proximal trailing end, a first face, and a second face. The distal leading end has a distal surface generally opposite a proximal surface of the proximal trailing end. The first face has a first surface that is generally parallel with a second surface of the second face. The first and second faces extend between the distal leading end and the proximal trailing end, such that the first and second surfaces slope upwardly from the distal lead end to the proximal trailing end along a length of extending proximally. The first and second surfaces having one or more textured features adapted to provide friction with the spinal facet joint. | 01-23-2014 |

20120093376 | NOISE REDUCTION OF IMAGING DATA - The present invention relates to systems and methods for reducing noise in image data. Preferred embodiments relate to methods for analyzing two-photon in vivo imaging of biological systems. With neuronal population imaging with subcellular resolution, this modality offers an approach for gaining a fundamental understanding of brain anatomy and physiology. Analysis of calcium imaging data requires denoising, that is separating the signal from complex physiological noise. To analyze two-photon brain imaging data, for example, harmonic regression plus colored noise model and an efficient cyclic descent algorithm for parameter estimation. This approach reliably separates stimulus-evoked fluorescence response from background activity and noise, assesses goodness of fit, and estimates confidence intervals and signal-to-noise ratio. | 04-19-2012 |
