Abstract: Methods and systems for generating a model to be used for evaluating credit and loan applications are provided. The method includes: training a first model by using all features included in a universe of candidate features; measuring a first metric that relates to an accuracy of the first model and a second metric that relates to a disparity of the first model; constructing a graph based on pairwise correlations of the features; clustering the features into feature sets; estimating a respective disparity contribution associated with each feature set; selecting feature sets to be included in a second model; training, the second model; measuring the first metric and the second metric with respect to the second model; and determining whether the second model satisfies a predetermined accuracy level and a predetermined disparity reduction with respect to the first model.

Abstract: The identification, function and application of m6A methylation site in the FAM134B mRNA. The main steps include confirming the m6A methylation site in FAM134B mRNA by comparative analyzing m6A-seq results of Landrace and Jinhua pigs, corresponding with highly conserved motif RRACH (R=G, A; H=A, C, T) and the prediction website; altering the m6A methylation in FAM134B mRNA via mutating synonymous codon of FAM134B gene (C1358 to T1358) without changing the amino acid sequence; designing qPCR primers according to the m6A peak region and a control region of FAM134B mRNA; extracting total RNA and determining the relative m6A level of a single gene by protein immunoprecipitation and qPCR. The m6A methylation site of FAM134B mRNA plays a critical rule on fat deposition, which serves as a novel molecular marker and a drug target for treating obesity.

Abstract: A method of synthesizing biogenic elemental selenium nanostructure using Enterobacter cloacae and its application. The method uses E. cloacae Z0206 to reduce selenite to zero valence selenium and forms nano-sized elemental selenium particles, including steps of inoculating activated E. cloacae Z0206 to fermentation broth, adding sodium selenite solution, shaking and incubating, collecting the fermentation broth and separating the elemental selenium nanoparticles.
