This paper first combines the traditional Adaboost iterative algorithm and logistic regression algorithm to construct an improved Adaboost based regression algorithm. In order to solve the problem of the redundant amount or insufficient amount of output of industrial carbon emissions, the SBM model is divided into two stages, and by merging this method, the industrial carbon emission efficiency measuring model is created, While the Global Moran’s I index is used to assess the geographical impact of industrial carbon emission efficiency. Additionally, a model of the influence of emission efficiency based on the geographical effect is built through the selection of the explanatory variables of the influencing factors. According to the study, the industrial carbon emission efficiency is growing at an annual rate of 1.8% during the period of fast expansion, 0.4% in the steady growth stage, and the Z value of STI is 0.38 is significant in spatial autocorrelation.

Among the numerous transmissible spongiform encephalopathies (TSEs), bovine spongiform encephalopathy (BSE) is the most well-known TSEs. It is a potential Creutzfeldt–Jakob (CJD) disease mutation that can be transferred through cattle to humans. In several animals, the prion protein gene (PRNP) is recognized to take active part in TSE vulnerability or tolerance. Previous studies have found indels polymorphism in PRNP gene promoter and intron1 region linked to BSE vulnerability. It's linked with 23 bp indels polymorphism in putative promoter and 12 bp indel in intron 1 of the PRNP gene. The aim of this study was to compare the allele, genotype and haplotype frequencies of PRNP indel polymorphisms in Zhongdian Yak (Bos grunniens) (YK), Zhongdian Yellow cattle (Bos taurus) (YC) and Zhongdian Yakow (Bos primigenius taurus × Bos grunniens) (PK) with worldwide reported healthy or affected BSE cattle, in order to assess their potential resistance to BSE. A comparison of Chinese bovine populations with healthy and BSE-affected German and Swiss cattle from globally was conducted, and result indicating significant difference (p <.001) between healthy and affected cattle. Additionally, as compared to prior studies with Chinese bovine population, the significant results were found. In this study, the allelic frequency D23 finding high deletion in all analyzed Chinese bovine species, and haplotype D12–D23 exhibited a less significant inclination toward susceptibility to BSE.

In this article, a degeneration method of inverse simulation is proposed for a helicopter system flying pull-up and slalom maneuvers. This inverse simulation method has been successfully applied, and here, the results are compared with the flight test data and the reference data, which indicate that this method has fidelity and is effective. It is different from conventional inverse simulation methods (i.e., the differentiation method and the integration method), and can improve numerical stability during inverse simulation, because the core principle is to solve the output vector in each simulation time step, by degenerating the system of first-order differential equations into nonlinear equations.
