20150247163 | COMPOSITIONS AND SYSTEMS FOR CONFERRING DISEASE RESISTANCE IN PLANTS AND METHODS OF USE THEREOF - Compositions, systems and methods are provided for conferring disease resistance to plant pathogens that use proteases to target plant substrate proteins inside plant cells. Briefly, the compositions, systems and methods are based upon plant substrate proteins that are targeted by pathogen-specific proteases and that activate nucleotide binding site-leucine rich repeat (NB-LRR) disease resistance proteins when cleaved by the protease. These substrate proteins are modified such that the endogenous protease recognition sequence is replaced by a protease recognition sequence specific to a different pathogen protease (i.e., a heterologous protease recognition sequence). The modified plant substrate protein therefore can be used in connection with its corresponding NB-LRR protein to activate resistance in response to cleavage by the heterologous pathogen-specific protease. When activated by the plant pathogen-specific protease, the pair initiates host defense responses thereto, including programmed cell death. | 09-03-2015 |

20150258482 | CENTRALIZED PURGING UNIT FOR ENGINE SUB-SYSTEMS - A purging system for an engine system is disclosed. The engine system includes an engine and one or more to-be-purged sub-systems. The purging system includes a centralized purging unit with one or more compressed air sources to store and provide compressed air. The compressed air sources are fluidly communicable with each of the to-be-purged sub-systems. A control valve assembly includes one or more valves that are operably positioned between the compressed air sources and the to-be-purged sub-systems. A controller, which is in control communication with the control valve assembly, is configured to alternate the valves between an active state and an inactive state. This is to vary the fluid communication between the compressed air sources and at least one of the to-be-purged sub-systems. This alteration is based on a set of predefined threshold conditions. | 09-17-2015 |

20100045978 | SPECTRAL SIGNATURE EXTRACTION FOR DRUG VERIFICATION AND IDENTIFICATION - Systems and methods perform signature extraction from an acquired spectrum of a pharmaceutical. An acquired spectrum of the pharmaceutical is measured using a spectrometer. The acquired spectrum is obtained from the spectrometer using a processor. A system-response function of the spectrometer is removed from the acquired spectrum using the processor. An intensity of the acquired spectrum is normalized to a predetermined scale using the processor. Fluorescence is removed from the acquired spectrum using the processor. Finally, an extracted signature of the pharmaceutical is obtained from the remainder of the acquired spectrum using the processor. If the acquired spectrum of the pharmaceutical is measured by the spectrometer through a container holding the pharmaceutical, a spectrum of the container is removed from the remainder of the acquired spectrum to produce the extracted signature of the pharmaceutical using the processor. | 02-25-2010 |

20080288255 | System and method for quantifying, representing, and identifying similarities in data streams - A method of quantifying similarities between sequential data streams typically includes providing a pair of sequential data streams, designing a Hidden Markov Model (HMM) of at least a portion of each stream; and computing a quantitative measure of similarity between the streams using the HMMs. For a plurality of sequential data streams, a matrix of quantitative measures of similarity may be created. A spectral analysis may be performed on the matrix of quantitative measure of similarity matrix to define a multi-dimensional diffusion space, and the plurality of sequential data streams may be graphically represented and/or sorted according to the similarities therebetween. In addition, semi-supervised and active learning algorithms may be utilized to learn a user's preferences for data streams and recommend additional data streams that are similar to those preferred by the user. Multi-task learning algorithms may also be applied. | 11-20-2008 |
