China’s rural area is vast, and in the process of diversified urbanization, the trend of rural diversity and differentiation will continue. To this end, the Strategic Plan for Rural Revitalization (2018–2022) in China specifically puts forward the work requirements of “strengthening the guidance of planning and focusing on implementing policies based on categories.” Based on POI data in 2020 and gravity model, this paper analyzes the geo-spatial interactions and main economic activities of 1183 rural settlements in a representative city called Yangzhou in Yangtze River Delta, and gives a classification of rural types in this region and an evaluation of the potential of rural revitalization of different categories. The research shows that there is still a great space for rural development in Yangzhou, but there is a problem of unbalanced village development, and the potential of rural revitalization is positively correlated with the relationship between policy and rural location. Through field visits to rural areas with potential for revitalization, it is found that they are mainly affected by urbanization and lack of labor and technical support, as well as lack of attention to social aspects in regional planning. In combination with the guiding ideology of the Strategic Plan for Rural Revitalization (2018–2022), this paper proposes that regional universities should play an important role in the process of realizing regional rural revitalization, and should carry out rural social practice and guide the local employment of college students. This way can realize the popularization of knowledge and make up for the lack of social research in the implementation of national planning and construction.

High Mn poisoned male and female Populus cathayana. The toxicity could be alleviated by exogenous ABA application. Intriguingly, ABA granted higher resistance to males than to females under high Mn stress because ABA could induce more blocking of Mn translocation to leaf in males than in females. Abscisic acid (ABA) is involved in plants' adaptive responses to various environmental stresses. However, little is known about the sex-related detoxification of ABA in plants under excess manganese (Mn) conditions. To reveal potentially different ABA detoxification mechanisms between Populus cathayana males and females against excess Mn exposure, photosynthesis performance, Mn2+ concentrations and morphologic changes were investigated. High Mn stress led to a more severe chloroplast destruction and, thus, greater reduction in the photosynthesis of P. cathayana females when compared to males. Under high Mn conditions, Mn reallocated mainly to leaves in females, while in males, it was distributed equally to roots and leaves. With the application of ABA, photosynthesis was restored more in males and more integrated grana in males than in females. It should be noted that Mn concentrations in males were lower in leaves and higher in roots and stems than those in females when treated with the combination of Mn and ABA. Conclusively, due to the reduction of root-shoot Mn transportation induced by ABA in P. cathayana males, males experienced less physiological injuries than do females, which suggest that males possess greater ABA-inducible resistance to Mn stress than do females.

The failure mode of structural instability failure caused by inner stress is unexpected collapse and has more dangerous than the intensity failure. While finite element buckling analysis, an efficient numerical method, can be used to research the stability of pressure vessel for various critical loads. In this study, the geometrical stiffness matrix is formed and several special working conditions are considered in finite element analysis process. Numerical examples are presented to verify the proposed design of the pressure vessel with shell framework because it is actually the critical step in the thin-walled shell configuration that tend to happen structural failure. The 3D model of pressure vessel was established and the buckling load calculations under the actual operating conditions have been carried out to obtain the modal deformation condition and the safety factor. The FEM analysis results performed by using ANSYS software showed that the structure has a smaller deformation and a higher structural stability, which indicated that the vessel design can meet the working condition requirements.

Lead zirconate titanate (Pb(Zr0.55Ti0.45)O3, PZT) ferroelectric thin films were successfully prepared on the Pt(111)/Ti/SiO2/Si(100) substrates by RF-magnetron sputtering method. The imprint properties of PZT films have been investigated at room temperature. Our experimental results indicate the voltage shift along with time is subjected to a logarithmic function, and the simulation results are identical with the experimental values. The rate of imprint is time inversely dependent.

There is a high electric field exists at the interface layer between electrode and ferroelectric film, electrons can be injected into the ferroelectric film through the interface layer from the electrode. Besides, oxygen vacancies re-arrangement can cause the ferroelectric fatigue during the process of the electron injection. Considering the two factors above, we proposed the ferroelectric fatigue model, and the simulation result matched the experimental result perfectly.

Imprint is an important effect of the failure mechanisms in ferroelectric memory devices. After the analysis of the forming mechanism of the interface layer between the ferroelectric film and the electrode, the basic idea we employ that the imprint was induced by the different defect's distribution which existed at grain boundaries and t the interface. The difference of the defect's distribution was induced by different thickness of the interface layer. The thickness dependence of coercive voltage shift and coercive voltage change rule with time validates our assumption.

SrBi2Ta2O9 (SBT) thin films with different textures were fabricated by pulsed laser deposition under different deposition conditions. The influence of the deposition condition on the texture of the SBT films can be explained by the interactions between the plume and the substrate. With the aid of x-ray diffractometry, piezoreponse scanning probe microscopy, and ferroelectric-property measurements, a correlation between the film texture, as well as the domain structure, and the ferroelectric properties was established. It was found that the ferroelectrics properties, such as the polarization and the coercive field, had a strong dependence on the texture of the SBT films. What's more, 90° domains were observed in the (115)-textured SBT films. These results are of interest for the fabrication of ferroelectric memories with fatigue free SBT thin films.

Wolframium ions doped SrBi 2 Ta 2 O 9 ceramics have been synthesized by the conventional mixed-oxide method. A sawtooth-like hysteresis loop was observed at low measuring-frequency. This phenomenon was thought to be related with the perturbation of the defect-dipole polarization under an external electrical field. A developed physical-model was derived on the basis of simplifying such perturbation to a simple harmonic pendulum oscillator, which combines physical considerations with the well-known Preisach model. On the hypothesis of the simple harmonic pendulum oscillator, the included-angle between the defect-dipole polarization and the elementary-dipole polarization can be expressed as the product of the defect-dipole relaxation velocity and permitted relaxation time. Simulation result was excellently agreed with the observed measurement.

In this paper we use some methods such as correlation analysis, single regression analyses and so on, to study the relationship between human capital structure and business performance with examples, from which we draw a series of conclusions: the shareholding of the actual controller and executives, pluralism of board chairman and CEO and the introduction of executives are positively correlated with business performance, the proportion of family directors on the board has an inverted U-shaped relationship with business performance: the proportion of independent directors on the board has no significant impact on business performance.

The comprehension of sexually different responses in dioecious plants to excess manganese (Mn) stress requires molecular explanation. Physiological and proteomic changes in leaves of Populus cathayana males and females were analyzed after 4 wk of exposure to Mn stress. Under excess Mn conditions, shoot height and photosynthesis decreased more in females than in males. Females also showed severe browning and subcellular damage, higher Mn2+ absorption, and different antioxidant enzyme activities compared with males. There were ten differently regulated protein spots induced by excess Mn stress. They were mainly related to photosynthesis, ROS cleaning, and cell signaling associated to ROS, plant cell death, heat shock, cell defense and rescue, and gene expression and regulation. Variation in protein expression between the sexes clearly showed that males have evolved more efficient photosynthesis capacity, more stable gene expression and regulation, and better cell defense and rescue to prevent further injury under excess Mn stress.

Male and female poplar ( Populus cathayana Rehd.) cuttings respond differently to salinity stress. To understand these differences better, comparative morphological, physiological, and proteomics analyses were performed. Treatments with different concentrations of NaCl applied to male and female poplar cuttings for 4 weeks showed that females reacted more negatively at the morphological and physiological levels than did males, visible as shriveled leaves, decreased growth, lowered photosynthetic capacities, and greater Na(+) accumulation. The proteome analysis identified 73 proteins from 82 sexually related salt-responsive spots. They were involved in photosynthesis, protein folding and assembly, synthesis and degradation, carbon, energy and steroid metabolism, plant stress and defense, redox homeostasis, signal transduction, and so forth. The sex-related changes of these proteins were consistent with the different morphological and physiological responses in males and females. In conclusion, the higher salt resistance of male P. cathayana cuttings is related to higher expression and lower degradation of proteins in the photosynthetic apparatus, more effective metabolic mechanism and protective system, and greater capacity of hydrogen peroxide scavenging. This research allows us to further understand the possible different management strategies of cellular activities in male and female Populus when confronted by salt stress.

A model of caseretrieving based on AHP is presented and the basic principle and process of CBR and AHP are introduced. With the development environment of CGI, the prototype system is developed, and the core source code and running interface are shown to confirm the effectivity and feasibility of this model.

Drought is a major abiotic stress, limiting the survival and growth of young plants. However, little is known about sex-dependent responses to drought at the proteome level. In this study, we carried out investigations on comparative proteomics, combined with physiological and organelle structure analyses, in males and females of Populus cathayana Rehd. Three-month-old poplar cuttings were treated at 30% of field capacity and at 100% field capacity as a control in a greenhouse for 40 days. Drought greatly inhibited plant growth, damaged the photosynthetic system and destructed the structures of chloroplasts, mitochondria and cellular membranes. However, males suffered less from the adverse effects of drought than did females. Using 2-DE, 563 spots were detected, of which 64 spots displayed significant drought effect and 44 spots displayed a significant sex by drought interaction effect. The results suggest that the different responses to drought stress detected between the sexes have a close relationship to the changes in the expression of sex-dependent proteins, including, e.g. photosynthesis-related proteins, homeostasis-related proteins and stress response proteins. These proteins could contribute to a physiological advantage under drought, giving potential clues for understanding sexual differences in the performance of plants in different environments.
