Patent number: 8554493Abstract: Cypoviruses and baculoviruses are notoriously difficult to eradicate because the virus particles are embedded in micron-sized protein crystals called polyhedra. The remarkable stability of polyhedra means that like bacterial spores these insect viruses remain infectious for years in soil. Although these unique in vivo protein crystals have been extensively characterized since the early 1900s, their atomic organization remains elusive. Here we describe the 2 crystal structure of both recombinant and infectious silkworm cypovirus polyhedra determined using 5-12 micron crystals purified from insect cells. These are the smallest crystals yet used for de novo X-ray protein structure determination. It was found that polyhedra are made of trimers of the viral polyhedrin protein and contain nucleotides. Although the shape of these building blocks is reminiscent of some capsid trimers, polyhedrin has a new fold and has evolved to assemble in vivo into 3-D cubic crystals rather than icosahedral shells.Type: GrantFiled: February 28, 2008Date of Patent: October 8, 2013Assignees: National University Corporation Kyoto Institute of Technology, Protein Crystal CorporationInventors: Peter Metcalf, Fasseli Joseph Coulibaly, Hajime Mori, Norio Hamada, Keiko Ikeda, Yui Lam Elaine Chiu, Hiroshi Ijiri

Patent number: 8380776Abstract: The overall material constant of a composite material is computed where the composite material includes multiple kinds of material components in a matrix phase, each of the material constants of the material components and the matrix phase being known. First, for the composite material, an equation, having the material constant of a virtual composite material as an unknown, is prepared by defining the virtual composite material in which each of the material components is dispersed in a form of spherical particles in the matrix phase at a known volume fractions. Next, the overall material constant of the virtual composite material is found as the overall material constant of the composite material by solving the equation. In this case, the equation is a recursive equation which is obtained using the self-consistent method. The volume fraction of a material component in the composite material is computed using the equation.Type: GrantFiled: March 2, 2009Date of Patent: February 19, 2013Assignee: The Yokohama Rubber Co., Ltd.Inventors: Nobuo Suzuki, Kazuyuki Kabe, Seiichi Nomura

Publication number: 20130030717Abstract: A method of characterizing an object includes determining a depth-wise composition of the object at a measurement site within the object. A property of the object within a region adjacent to the measurement site can, optionally, be estimated based on the determining. Another method of characterizing an object includes disposing at least a portion of an object within a measurement region of a metrology tool, aligning a feature of the object and a location of a designated measurement site within the measurement region relative to each other, and performing a performing a compositional analysis of a portion of the object occupying the measurement site. Various apparatus for performing these methods are also disclosed, as are methods of monitoring manufacturing processes based on these methods.Type: ApplicationFiled: July 25, 2012Publication date: January 31, 2013Applicant: ELECTRO SCIENTIFIC INDUSTRIES, INC.Inventors: Jonathan D.

Patent number: 8354634Abstract: A mass spectrometer is disclosed wherein an ion signal is split into a first and second signal. The first and second signals are multiplied by different gains and are digitised. Arrival time and intensity pairs are calculated for both digitised signals and the resulting time and intensity pairs are combined to form a high dynamic range spectrum. The spectrum is then combined with other corresponding spectra to form a summed spectrum.Type: GrantFiled: May 22, 2008Date of Patent: January 15, 2013Assignee: Micromass UK LimitedInventors: Martin Green, Steven Derek Pringle, Jason Lee Wildgoose

Patent number: 8344315Abstract: The invention is a process for finding the accurate masses of subfragments comprising an unknown compound from the accurate-mass mass spectral data of the unknown compound obtained on a mass spectrometer. This process generates these accurate masses of subfragments using mass differences of fragment ions and a listing of plausible masses. In this way, the accurate masses of subfragments, useful for generating modular structures, can be obtained very rapidly.Type: GrantFiled: May 27, 2010Date of Patent: January 1, 2013Assignee: Math Spec, Inc.Inventor: Daniel Leo Sweeney

Patent number: 8332160Abstract: Systems and methods are provided for defining a nucleic acid construct for integration at locus L of an organism. Nucleic acid requests are received, each such request specifying a genetic change to L. The request are expanded into component polynucleotides which are then arranged into {AR1, . . . , ARm} different arrangements, each ARi in {AR1, . . . , ARm} defining a different arrangement of the component polynucleotides. A score Si for each ARi in {AR1, . . . , ARm} is determined based on whether source constructs encoding a portion ofARi are physically present. An ARf in {AR1, . . . , ARm} is selected based on the score for ARf. Primer pairs are calculated to amplify the portions of ARf not represented in the source constructs. The portions of ARf amplified by the primer pairs and the portions of ARf in the source constructs, ordered by ARf, define the nucleic acid construct.Type: GrantFiled: April 9, 2012Date of Patent: December 11, 2012Assignee: Amyris Biotechnologies, Inc.Inventors: Darren M. Platt, Michael W. Bissell, Sunil S. Chandran, Brian L. Hawthorne, Erik Jedediah Dean, Christopher Dolan
