- Abstract
Surface-enhanced Raman scattering (SERS) technology, which enables the rapid detection of trace molecules, has gained widespread attention in areas such as pharmaceutical material analysis, identification of hazardous substance residues, and food safety. The response limit of SERS to the detected substances depends on the performance of the substrate and directly affects the final detection effect. In this paper, MoO3-x nanoslots with oxygen vacancy defects were successfully prepared by a simple hydrothermal method with the aim of increasing the specific surface area of the substrate and its ability of photoinduced charge transfer between the substrate and the detected substances. The electronic structure, optical properties and surface chemical environment of the MoO3-x nanoslots were analyzed by a combination of X-ray photoelectron spectroscopy (XPS), ultraviolet-visible spectroscopy (UV-Vis) and Fourier transform infrared spectroscopy (FT-IR). Three organic dye molecules, rhodamine 6G (R6G), crystalline violet (CV) and rose red B (RhB), were detected using the MoO3-x nanoslots as SERS substrates, and the experimental results show that the detection limit of R6G could reach 10 -10 mol/L, and it has better Raman-enhancing activity compared with the same type of semiconductor substrates.

- Abstract
In order to solve the numerical instability problem in the nonlinear topology optimization of the compliant constant force mechanism, the material interpolation method of nonlinear topology optimization was investigated. First, the design domain and nonlinear topology optimization model were constructed according to the characteristics of the constant force mechanism. Then, the reasons for the numerical instability problem were discussed, and a new material interpolation model was proposed to avoid the numerical instability problem by controlling the strain, in which a parameter α was introduced to realize the simultaneous adjustment of the deformation resistance of lowdensity elements. An adaptive adjustment strategy of parameter α was given according to the maximum equivalent strain. Finally, based on the proposed material interpolation model, the sensitivity equation of the objective function of the optimization model was deduced. Constant force mechanisms with different constant force intervals were optimized, the optimization results and the optimization efficiency were discussed. An experimental platform was built to validate the actual output performance of the optimized constant force mechanism. The experimental results show that the maximum output force error of the constant force mechanism optimized by this method is 2. 3% in the given constant force interval. The results show that the adaptive material interpolation method effectively avoids the numerical instability problem, the stability is improved, and the optimization efficiency is improved compared with the additional hyperplastic material method.

- Abstract
Objective: To investigate the risk factors of unusable embryos after egg retrieval in vitro fertilization (IVF)/intracytoplasmic sperm injection (ICSI) in older women. Methods: A total of 569 egg retrieval cycles of older women who underwent IVF/ICSI assisted pregnancy in the Reproductive Center of Hebei Reproductive Health Hospital from January 2015 to December 2021 were retrospectively analyzed, including 95 cycles with unusable embryos as the study group and 474 cycles with usable embryos as the control group. According to the age, each group was divided into three subgroups: G1 group aged 35 to 39 years, G2 group aged 40 to 42 years, and G3 group aged 43 to 45 years. Ovulation induction and laboratory indexes were compared. Results: The differences of age, infertility years, body mass index (BMI), basic follicle-stimulating hormone (FSH), basic estradio (E2), anti-Müllerian hormone (AMH) and antral follicle count (AFC) on the start day in the corresponding subgroups between the two groups were not statistically significant (all P>0.05). There were significant differences in the level of luteinizing hormone (LH) on the trigger day between G2 subgroups (P<0.05). On the trigger day, the differences in the E2 level and follicular output rate (FORT) between G1 and G2 subgroups of both groups were statistically significant (all P<0.05). The differences of preponderance follicle count (PFC) on the trigger day among the three subgroups of both groups were statistically significant (P<0.05). There were no significant differences in gonadotropin (Gn) dosage, Gn days, trigger action time, trigger day progesterone (P) level and trigger day E2/PFC among 3 subgroups of both groups (all P>0.05). Meanwhile, the differences in the number of eggs obtained, the number of MⅡ eggs, the total number of fertilization, the total number of cleavage, the number of 2PN and the number of 2PN cleavage statistically significant (all P<0.05). Interestingly, Logistic regression analysis showed that the infertility year was a risk factor of unusable embryos after egg retrieval, while PFC on the trigger day was a protective factor. Conclusions: In IVF/ICSI assisted pregnancy for older women, the occurrence of non-transplantable embryos will increase with the increase of infertility years, while the increase of PFC on the trigger day will reduce the risk of non-transplantable embryos.

VIRTUAL networks , *ENERGY harvesting - Abstract
Green Mobile Edge Networks(GMENs) is an emerging distributed network that uses renewable green energy as the main energy source for edge nodes to operate, thereby reducing energy acquisition from the power grid. In GMENs, network service providers can form a service function chain(SFC) of multiple virtual network functions(VNFs) in a specific order to process user requests. These VNFs can flexibly deploy in the form of software instances on edge nodes to efficiently utilize green energy. To ensure the latency and reliability requirements of the service, it is necessary to deploy multiple backup VNFs(BVNF) on nodes within a k-hop range of VNF, to replace it in providing services that meet the latency requirements in the event of VNF failure. However, the green energy collected by each geographically dispersed edge node is dynamically changing. If the collected energy of nodes around the VNF decreases and is less than the energy consumption required to operate the BVNF, the node needs to harvest additional energy from the grid to guarantee its operation. Therefore, developing an online joint deployment plan for VNF and BVNF based on the green energy collected by nodes and the energy rate consumed by computing, communication, and other resources is an NP-hard problem, which minimizes the energy obtained by edge nodes from the power grid while ensuring service latency and reliability requirements. At present, there have been many studies on this issue and certain achievements have been made, but there are still some problems in practical applications. To further promote research in this field, this article analyzes, summarizes, and compares the latest research achievements in recent years, their advantages and disadvantages, and provides prospects for future work.

- Abstract
The reactions of a series of iminium anions with methylethyl sulfite in some same ratios(5:5, 10:10, 20:20, 50:50) and in different ratios(20:30, 20:40, 20:50 and 30:20, 40:20, 50:20) were studied by molecular dynamics methods, the results showed that a higher amount of iminium was converted to ammonia, while methyl ethyl sulfite was decomposed into substances such as methanol, ethanol and some small carbon compounds. The study of the reaction mechanism at the level of 6-311++G(3 df, 3 pd) by both B3 lyp and Bhandhlyp of density flooding showed that this reaction is a multi-channel and multi-step reaction system, and both the primary and secondary reactions are exothermic, in which the paths that the products produced are P1(CH3OSO2- + NH3 + C2H4), P2(CH3OSO2- + NH2CH2CH3), and P3(CH2O + SO2 + NH3 + C2H5-) are the best reaction channels, while the generation of P4(CH3NH2- + CH3CH2OSO2) and P5(CH3- + NH3 + SO2 + CH3CHO) are the next best, all of which are experimentally detectable. The production processes of products P6(CH3CH2OH + NSO- + CH2OH), P7(CH2O + NH3 + CH3CH2OSO) and P8(CH3CHO + NH3 + CH3OSO) are secondary pathways of the title reaction due to the presence of higher potential barriers. The results of the theoretical calculations agree with the experimental results. [ABSTRACT FROM AUTHOR]

- Abstract
A suitable high-temperature steam heat pump system based on multi-objective optimization is designed to save energy and reduce emission. Firstly, the calculation method of exergic efficiency of high temperature steam heat pump was proposed after the explanation of each subsystem, the study of system mechanism and establishment of the system’ s static model. Then, the optimization parameters and optimization indexes of the system structural parameter optimization were determined. Exergic efficiency and all cost were taken as the optimization objective, and the multi-objective artificial bee colony algorithm (MOABC) was used to establish the multi-objective optimization model of high-temperature steam heat pump. Finally, MOABC was optimized for exergic loss and COP(coefficient of performance) of the system under different working conditions. Experiments show that exergic efficiency as energy efficiency index can improve the energy quality of high temperature steam heat pump system.

The integrated development of culture and tourism is one of the important ways for China to promote rural revitalization in the new era. Guangdong-Hong Kong-Macao Greater Bay Area uses the unique lychee cultural resources of the Lingnan region for tourism development, and has formed many local experiences and typical models on the road of integrated development of culture and tourism. This paper summarized the development connotation of litchi cultural resources in Guangdong-Hong Kong-Macao Greater Bay Area. Based on the existing studies on the integration of lychee cultural tourism, from the perspective of industrial economy, the experience of the integrated development of lychee cultural tourism in the Greater Bay Area is divided into four typical models: the integrated development mode of popular science research, the integrated development mode of cultural festival, the integrated development mode of picking experience, and the integrated development mode of industry and tourism joint operation. Through in-depth analysis of the main characteristics of different modes and typical case practice, the specific path and industry dynamics of the integrated development of lychee cultural tourism in the Greater Bay Area were clarified. Finally, from the perspective of problems, it is proposed that the Greater Bay Area can carry out mechanism innovation in the following aspects, such as government role, platform construction and public participation, so as to promote the integration of lychee culture and tourism to achieve a unified development direction of social benefits, cultural benefits and economic benefits. For the first time, this paper makes a comprehensive interpretation of lychee cultural tour, which relies on local fruit cultural resources to design rural revitalization road. The research results can provide some enlightenment for other areas to implement rural revitalization integrated development of cultural tourism. [ABSTRACT FROM AUTHOR]

【Objective】The new urbanization strategies provide new opportunities for farmers to increase their income, and adjusting its action path according to the specific impact of the new urbanization can promote the growth of farmers' income more effectively.【Method】Based on the urban panel data of the Pearl River Delta region from 2010 to 2021, the kernel density estimation was used to analyze the dynamic evolution trend of farmers' income, and the fixedeffect model was used to empirically analyze the impact effect of the new urbanization level on farmers' income.【Result】 The results show that during the research period, the farmers' income level in the Pearl River Delta region has increased significantly, the sources of farmers' income are diversified, income from wages and salaries is still the main component, income from property such as housing rental has been an important source, the absolute gap between farmers' income levels between cities is expanding, and the income levels between the urban areas spread to the high value area and the spatial agglomeration characteristic is obvious, and the economic urbanization has the strongest effect on farmers' income. However, at present, the new urbanization development in the Pearl River Delta region still has some problems, such as low quality of urbanization, mismatch between supply and demand, large income gap between urban and rural areas, and shortage of land resources. 【Conclusion】It is suggested that when pushing the people-centered urbanization strategy in the Pearl River Delta cities. it should focus on improving the quality of urbanization of agricultural migrants and promoting the integration of agricultural migrants into cities; insist on optimizing the local industrial structure, vigorously developing non-agricultural industries such as modern service industry, and creating more jobs to maximize the farmers' income effect of urbanization.
