Endophytes play an important role in the growth and development of the host. However, the study of endophytes is mostly focused on plants, and reports on bacteria associated with fungi are relatively rare. We studied the bacteria associated with fruiting bodies of Tricholoma matsutake picked from seven main T. matsutake-producing areas in Sichuan, China, by barcoded pyrosequencing. About 8,272 reads were obtained per sample, representing 40 phyla, 103 classes, and 495 genera of bacteria and archaea, and 361.797 operational taxonomic units were observed at a 97% similarity level. The bacterial community was always both more abundant and more diverse than the archaeal community. UniFrac analysis showed there were some difference of bacterial communities among the samples sites. Three bacterial phyla, Proteobacteria, Bacteroidetes, and Firmicutes, were dominant in all samples. Correlation analysis showed there was a significant correlation between some soil properties and bacterial community associated with T. matsutake. This study demonstrated that the bacteria associated with T. matsutake fruiting bodies were diversified. Among these bacteria, we may find some strains that can promote the growth of T. matsutake.

An unstructured mathematical model for lactic acid fermentation was developed. This model was able to predict the inhibition effects of lactic acid and glucose and was con-firmed to be valid with various initial concentrations of lactic acid and glucose. Simulation of energy production was made using this mathematical model, and the relationship between the kinetics of energy metabolism and lactic acid production was also analyzed.

Purpose: Dissection after plain balloon angioplasty is required to achieve adequate luminal area; however, it is associated with ahigh risk of vascular events. This study aimed to examine the relationship between non-flow limiting coronary dissections andsubsequent lumen loss and long-term clinical outcomes following successful drug-coated balloon (DCB) treatment of de novocoronary lesions. Materials and Methods: A total of 227 patients with good distal flow (Thrombolysis in Myocardial Infarction flow grade 3) followingDCB treatment were retrospectively enrolled and stratified according to the presence or absence of a non-flow limiting dissection. The primary endpoint was late lumen loss (LLL) at 6-month angiography, and the secondary endpoint was target vesselfailure (TVF, a composite of cardiac death, target vessel myocardial infarction, target vessel revascularization, and target vesselthrombosis). Results: The cohort consisted of 95 patients with and 132 patients without a dissection. There were no between-group differencesin LLL (90.8%) returning for angiography at 6 months (0.05±0.19 mm in non-dissection and 0.05±0.30 mm in dissection group, p=0.886) or in TVF (6.8% in non-dissection and 8.4% in dissection group, p=0.799) at a median follow-up of 3.4 years. In a multivariateanalysis, the presence of dissection and its severity were not associated with LLL or TVF. Almost dissections (93.9%) were completelyhealed, and there was no newly developed dissection at 6-month angiography. Conclusion: The presence of a dissection following successful DCB treatment of a de novo coronary lesion may not be associatedwith an increased risk of LLL or TVF (Impact of Drug-coated Balloon Treatment in de Novo Coronary Lesion; NCT04619277).
Privacy-Preserving One-Class Support Vector Machine with Vertically Partitioned Data
Qiang Lin,Huimin Pei,Kuaini Wang,Ping Zhong 보안공학연구지원센터 2016 International Journal of Multimedia and Ubiquitous Vol.11 No.5
We establish a new model of privacy-preserving one-class support vector machine (SVM) based on vertically partitioned data. Every participant holds all the data with a part of attributes. They apply different random matrices to establish their own kernel matrix. By sharing these partial kernel matrices, we construct a global kernel matrix and establish linear and nonlinear privacy-preserving models. Experimental results on benchmark data sets verify the validity of the proposed models.

In this study, numerical investigations of the tip clearance flow characteristics of a pumpjet propulsor based on Computational Fluid Dynamics (CFD) method have been presented. The Zwart-Gerber-Belamri (Z-G-B) cavitation model based on Reynolds Averaged NaviereStokes (RANS) method is employed. The structured gird is applied. The formation and development of the tip clearance flows has been investigated and presented. The structure of the tip leakage vortex has been shown. The radial distributions of different velocity components with different Span along the axial direction have been carried out to present the influence of the tip clearance flow on the main flow. In addition, the influences of the tip clearance size on the pumpjet propulsor performance, including the impact on the velocity flow fields and the cavitation characteristic, have been presented.
Privacy-Preserving One-Class Support Vector Machine with Horizontally Partitioned Data
Qiang Lin,Huimin Pei,Kuaini Wang,Ping Zhong 보안공학연구지원센터 2016 International Journal of Signal Processing, Image Vol.9 No.9
We propose a new algorithm of privacy-preserving one-class support vector machine (SVM) with horizontally partitioned data. Every participant holds a part of data with all the data attributes. They apply the same random matrix to establish their own kernel matrix. By sharing these partial kernel matrices, we generate a global kernel matrix and establish two privacy-preserving one-class SVM models, which include the linear model and the nonlinear model. Partial kernel matrix can protect the privacy of the participants, and the global kernel matrix can ensure the classification accuracy. Experimental results on benchmark data sets indicate the effectiveness of the proposed algorithms.

Qiang Lin,Sheng-Cai Li,Yongfu Zhu 국제구조공학회 2021 Structural Engineering and Mechanics, An Int'l Jou Vol.77 No.2
The energy-saving block and invisible multi-ribbed frame composite wall (EBIMFCW) is a new type of load-bearing wall. The study of this paper focus on it is hysteresis rule under horizontal cyclic loading. Firstly, based on the experimental data of the twelve specimens under horizontal cyclic loading, the influence of two important parameters of axial compression ratio and shear-span ratio on the restoring force model was analyzed. Secondly, a tetra-linear restoring force model considering four feature points and the degradation law of unloading stiffness was established by combining theoretical analysis and regression analysis of experimental data, and the theoretical formula of the peak load of the EBIMFCW was derived. Finally, the hysteretic path of the restoring force model was determined by analyzing the hysteresis characteristics of the typical hysteresis loop. The results show that the curves calculated by the tetra-linear restoring force model in this paper agree well with the experimental curves, especially the calculated values of the peak load of the wall are very close to the experimental values, which can provide a reference for the elastic-plastic analysis of the EBIMFCW.
