摘要:
The reconstruction of genetic networks in mammalian systems is one of the primary goals in biological research, especially as such reconstructions relate to elucidating not only common, polygenic human disease, but living systems more generally. The present invention provides novel gene network reconstruction algorithms that utilize naturally occurring genetic variations as a source of perturbations to elucidate the networks. The algorithms incorporate relative transcript abundance and genotypic data from segregating populations by employing a generalized scoring function of maximum likelihood commonly used in Bayesian network reconstruction problems. The utility of these novel algorithms can be demonstrated via application to gene expression data from a segregating mouse population. The network derived from such data using the novel network reconstruction algorithm is able to capture causal associations between genes that result in increased predictive power, compared to more classically reconstructed networks derived from the same data.

The invention discloses a filter-tipped cigarette comprising a filter tip. The filter tip comprises a plurality of filter elements twisted together by mutually winding. All the filter elements are cellulose acetate fiber bundles. In the invention, since the filter elements are disposed in the way of winding, a total length of the filter elements is increased, a travel of a smoke passing through the filter elements is thereby increased, and thus harmful ingredients in the cigarette are filtered more thoroughly.

A method and a system for identifying and resolving conflicts between design results from a parallel software design. The method includes: receiving a design diagram, wherein the design diagram includes a plurality of nodes and arrows connecting different nodes, with each node indicating a design artifact, and an arrow directed from one node to another node indicating that a design artifact corresponds to the one node depends on a design artifact corresponding to the other node; determining a level of a design artifact in the design diagram, identifying different design artifacts at a given level of the design diagram that depend on a common design artifact, and marking them as isomorphic design artifacts; and outputting a design diagram with the isomorphic design artifacts marked. A conflict between relevant designs are automatically identified in a bottom-up approach according to a software design hierarchy to facilitate conflict resolution.

Systems, power modules (108), and methods (200) for using in controlling a converter (110) coupled between a power generator (104) and an electric grid (102) are provided. One of the power modules (108) includes the converter (110) configured to supply an output from the power generator (104) to the electric grid (102), and a controller (112) coupled to the converter (110). The controller (112) includes a phase-lock-loop (PLL) module (123) and at least one regulator (128, 130). The at least one regulator (128, 130) is configured to at least partially control the converter (110) as a function of at least one parameter. The controller (112) is configured to disable the converter (110) in response to a grid fault event, to maintain coupling between the power generator (104) and the converter (110) during the grid fault event, to determine whether the PLL module (123) is locked onto a voltage associated with the electric grid, to adjust the at least one parameter after the grid fault event, and to re-enable the converter to supply the output from the power generator (104) to the electric grid (102).

A method for measuring intensity distribution of light includes a step of providing a carbon nanotube array having a top surface. The carbon nanotube array is located in an inert gas environment or a vacuum environment. A light source irradiates the top surface of the carbon nanotube array, to make the carbon nanotube array radiate a radiation light. An imaging element images the radiation light, to obtain an intensity distribution of the light source.

A method is implemented in a computer infrastructure having computer executable code tangibly embodied on a computer readable storage medium having programming instructions. The programming instructions are operable to receive one or more risk factors, receive one or more contexts, identify one or more context relationships and associate the one or more contexts with the one or more risk factors. Additionally, the programming instructions are operable to map the one or more risk factors for an associated context to a software defect related risk consequence to determine a risk model and execute a risk-based testing based on the risk model to determine a defect related risk evaluation for a software development project.
