  • Publication number: 20180018335
    Abstract: Attribute information of a pending data handling process to be performed is identified. Historical data handling processes for a same application scenario as the pending data handling process are identified based on the attribute information. A time that each identified historical data handling process is performed and methods used to perform the identified historical data handling processes are also identified. A weighting coefficient for each identified historical data handling process is determined. Weighted identified historical data handling processes are calculated by applying the weight coefficient to each identified historical data handling process. A recommended weight for each method used to perform the identified historical data handling processes is determined by combining weighted identified historical data handling processes that use the same method. A method that has the highest recommended weight to perform the pending data handling process is recommended.

  • Patent number: 9795694
    Abstract: The present invention is in the field of pharmaceuticals and chemical industries. In particular, one aspect of the present invention relates to methods for labeling, imaging and detecting the beta-amyloid (A?) peptides, oligomers, and fibrils in vitro and in vivo via magnetic resonance and florescence imaging by using modified carbazole-based fluorophores. A further aspect of the present invention relates to a method of reducing and preventing aggregation of beta-amyloid peptides for Alzheimer's disease (AD) as well as of treating and/or preventing Alzheimer's disease by using the modified carbazole-based fluorophore. The modified carbazole-based fluorophore according to an embodiment of the present invention is prepared by conjugating a carbazole-based fluorophore with magnetic nanoparticles to form a conjugate which is permeable to blood brain barrier of a subject being introduced therewith.

  • Patent number: 9715726
    Abstract: A method and apparatus for B0 correction in echo-planar (EP) based magnetic resonance image (MRI) is disclosed. Two phase images are obtained from each of a first echo-planar imaging (EPI) acquisition and a second EPI acquisition. A first susceptibility map is generated based on the two phase images obtained from the first EPI acquisition and a second susceptibility map is generated based on the two phase images obtained from the second EPI acquisition. A smooth polynomial function for modeling the B0 drift and respiratory motion between the first EPI acquisition and the second EPI acquisition is initialized based on the first and second susceptibility maps. A compensated temperature map is then iteratively reconstructed based on the smooth polynomial function.

  • Publication number: 20170193531
    Abstract: In accordance with one embodiment, a market influence analysis engine assesses the potential market influence of digital media content items and/or the influence of associated content creators. The market influence analysis engine identifies digital media content items associated with at least one user-provided content descriptor, sorts the identified digital media content items into different groups such that the digital media content items in each group are associated with a different one of the plurality of content creators. The market influence analysis engine further calculates an influence score associated with each one of the content creators that is based on consumer influence metrics. A subset of the groups for which the calculated influence score satisfies a predetermined influence threshold is identified and information representing such groups is transmitted for presentation to a user interface.

  • Publication number: 20170118283
    Abstract: A system, computer program product, and method is described to manage cloud bursting from a private cloud to a public cloud. The method starts with executing one or more software components of at least one application receiving transaction requests on at least one processing node accessing at least one database server. The one processing node is managed by at least one controller in a first deployment model of a computing infrastructure. The controller, the processing nodes and the database servers each include instrumentation for tracking of performance metrics thereof. A map is created of transaction requests received by the controller to data resources in the database by analyzing the set of common structures. The map is used to identify which of the software components and corresponding data resources in the database to move a processing node in a second deployment model of a computing infrastructure.

  • Patent number: 9413221
    Abstract: A power conversion unit includes power converters arranged sequentially to each other to convert input power that is provided at an input of the power conversion unit to output power. A set of first capacitors are arranged in series with each other and include, for each power converter, a first capacitor that is arranged in parallel with an associated power converter. Each first capacitor is also arranged to store a portion of the input power. A set of second capacitors are connected in series with each other and include a second capacitor connected between each pair of sequential power converters in the sequence. The set of second capacitors are arranged to balance the portion of the input power stored by each first capacitor.

  • Patent number: 9104902
    Abstract: A system and method for registering three-dimensional images with two-dimensional intra-operative images includes segmenting (24) a tubular structured organ in a three-dimensional image of the organ, and projecting (26) the three-dimensional image of the organ into two-dimensional space to provide a projected image. A medical instrument depicted in a two-dimensional image of the medical instrument is segmented (28). A similarity score is computed between the projected image and a shape of the medical instrument depicted in the two-dimensional image to determine a best match. The projected image is registered (30) to the two-dimensional image based on the best match.
