    摘要： Wavelength-based optical power provisioning is provided by multiplexing a plurality of continuous wave light beams at different wavelengths onto a single optical fiber as a multiplexed light source and demultiplexing the multiplexed light source based on wavelength at a photonic unit coupled to the optical fiber to recover the continuous wave light beams. The recovered continuous wave light beams are split into a plurality of light beams by the photonic unit, each light beam having the same wavelength and the same or lower power as one of the recovered continuous wave light beams so that at least one of the light beams generated by the photonic unit has a higher power than the other light beams generated by the photonic unit.

    摘要： Optical waveguide coupling ratios can be modified for a package by providing a substrate with a photonic circuit disposed on a first section of the substrate and a plurality of optical waveguides formed in glass disposed on a second section of the substrate, the waveguides being connected to the photonic circuit, adjacent ones of the waveguides having a fixed coupling ratio. A three-dimensional region of the glass abutting an end of one or more of the waveguides is lased to change a refractive index of the glass in each three-dimensional region, and thereby extend a length of each waveguide abutting one of the three-dimensional regions so that the coupling ratio between that waveguide and an adjacent waveguide is changed as a function of the extended length. The lasing is controlled based on feedback so that each coupling ratio changed by the lasing varies by less than a target amount.

    摘要： A rhizopus oryzae strain, mutagenesis and screening methods thereof, and methods of producing fumaric acid by fermentation. The strain is named as Rhizopus oryzae ME-F13, and deposited in China Center for Type Culture Collection with depository number CCTCC M 2010351. The strain is obtained by physically mutagenizing the original strain ME-F12 through ion injection, culturing the processed bacteria on the solid selective plate containing 2-D-deoxylucose (2-DG) and picking up 2-DG-resistant single colony. The strain is capable of simultaneously saccharifying starchy material and fermenting it to produce fumaric acid. With an improved enzymatic activity, the strain can be directly used to ferment raw starchy materials without needing pre-saccharifying.

    摘要： A method and system for segmentation of the corpus callosum in MR brain images is disclosed. The method utilizes an active shape model (ASM) with confidence weighting to iteratively adjust an initial corpus callosum contour to define a boundary of the corpus callosum in an MR image. An ASM is used to determine a displacement value in a perpendicular direction of the corpus callosum contour for each node of the corpus callosum contour. The displacement value for each node is then weighted based on a confidence of that displacement value. The ASM is then fitted to the adjusted contour. These steps are iteratively performed until the contour converges to define the corpus callosum boundary. This boundary can be further refined based on intensity distributions in object and background regions defined by the boundary.
