Since the new tunnel is close to existing tunnel, the vibration wave induced by blasting endangers the safety and stabilization of the surrounding rock and the lining of existing tunnel. In the tunnel blasting vibration monitoring and safety prediction, Peak Particle Velocity (PPV) and vibration frequency are used widely as safety standards. To investigate the effect of blast-induced vibration from adjacent tunnel on existing tunnel, field monitoring experiments and a numerical method that is Finite Element Method (FEM) were adopted to study the blasting vibration velocity and vibration frequency of existing tunnel. Combined blasting vibration velocity with vibration frequency, the paper studied axial and radial blasting vibration velocity distributions and the corresponding Power Spectral Density (PSD) distributions of the existing tunnel under the effect of blast-induced vibration from adjacent subway tunnel. And the parameters of constitutive model and blasting loads were also discussed. It is shown that field monitoring experiment and numerical simulation can optimize blasting excavation program and provide a reference for other similar engineering projects.

We adopt the PASTEL catalog combined with SIMBAD radial velocities as a testing standard to validate the stellar parameters (effective temperature $T_{eff}$, surface gravity log g, metallicity [Fe/H] and radial velocity $V_r$) from the first data release (DR1) of The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST) survey. After applying data reduction and temperature constraints to the sample obtained by cross-identification, we compare the stellar parameters from DR1 and PASTEL. The results show that the DR1 results are reliable under certain conditions. We derive a dispersion of 110 K, 0.19 dex, 0.11 dex and $4.91kms^{-1}$ in specified effective temperature ranges, for $T_{eff}$, log g, [Fe/H] and $V_r$ respectively. Systematic errors are negligible except for those of $V_r$. In addition, for stars with PASTEL [Fe/H] < -1:5, the metallicities in DR1 are systematically higher than those in PASTEL.

China"s economy is shifting from a stage of high-speed growth to a stage of high-quality development. How to use increasing foreign direct investment to enhance China"s overall technological innovation capability and promote "innovation-driven" strategic transformation has become the focus of attention everywhere. Based on the analysis of the characteristics of Jiangsu Province’s foreign direct investment, This essay also analyzed the panel data in 13 cities of Jiangsu Province in 11 years to find out its reverse technological overflow effect of OFDI. Research has found out that OFDI has positive influence on the regional innovation capacity in Jiangsu Province. After further analysis in different regions in Jiangsu province, it should be noted that different regions of Jiangsu Province are in the different development stages of OFDI. In the end, we can conclude some constructive suggestions and policy recommendations for the effective improvement of the reverse technology spillover effect of Jiangsu’s OFDI on technological progress.
OFDI对中国江苏区域创新能力的影响研究 ——基于吸收能力的视角
郭化?(Hua-Bing Guo) 한국아시아학회 2020 아시아연구 Vol.23 No.4
Based on the review of the existing theories and literature and the analysis of the development status and characteristics of Jiangsu’s OFDI, this paper carries out the empirical analysis as follows. The Hansen’s dynamic panel threshold model is applied to measure the threshold effect in terms of research and development(R&D) level, human resources, economic development level, financial development level and economic openness. The results show that there are minimum threshold requirements for other four other absorptive capacity indicators except the R&D level. Meanwhile, there is a ceiling limit threshold for economic development level, financial development level and economic openness, which means when the three indexes develop into moderate scale, the reverse technology spillover effect of OFDI would play a more positive role.

Light intensity and quality affect photosynthesis, plant morphology, and the synthesis of primary and secondary metabolites. Dysosma versipellis (Hance) M. Cheng is an endangered species endemic to China, and a highly valued medicinal and ornamental plant. In this study, we discuss the effects of different light spectrums conferred by colored plastic films on photosynthesis and the contents of active ingredients of D. versipellis. D. versipellis plants were cultured for 90 days under white, red, yellow, or blue film. The blue film treatment generally increased the chlorophyll content, photosynthetic rate (Pn), maximal photochemical efficiency of PSII (Fv/Fm), actual photochemical efficiency of PSII (ФPSII), photochemical quenching (qP), and the podophyllotoxin content of the rhizomes. The blue film treatment also decreased the maximum net photosynthetic rate (Amax), apparent photosynthetic quantum efficiency (AQY), and podophyllotoxin contents of the stems. The yellow film treatment resulted in a decline of the Amax, AQY, Fv/Fm, ФPSII, qP, chlorophyll contents, and podophyllotoxin contents of the leaves and rhizomes; however, the light compensation point (LCP), light saturation point, and minimum fluorescence (Fo) were increased. There were no significant differences in chlorophyll content, Amax, LCP, AQY, Fv/Fm, ФPSII, or qP between the white and red film treatments. These results suggest that in D. versipellis, blue film treatments promote photosynthesis and the accumulation of podophyllotoxin, while yellow film treatments inhibit photosynthesis and the accumulation of podophyllotoxin.

The use of artificial intelligence (AI) service robots is on the rise. With service frontlines gradually shifting to human–robot interactions, the question of whether AI robots should be humanlike or machinelike has emerged. While many firms use robots that resemble humans in their appearance and actions, others use machinelike robots, assuming that very humanlike robots may lead to uncanny valley effects. There is no consensus on whether the anthropomorphism of service robots facilitates or constrains consumers’ experiences. To fill this gap, this article examines when and how service companies should use anthropomorphic AI service robots.

Drought and hot stresses are the primary limiting factors for the growth and seed production of yellow-horn (Xanthoceras sorbifolia Bunge), especially in Xinjiang Province of China. A better understanding of its physiological and biochemical characteristics under drought–hot stress is requisite for its efficient cultivation in the arid and semi-arid areas. In this study, the physiological and biochemical responses of 3-month-old yellow-horn seedlings were evaluated after 7 days of treatments of five temperatures (25 °C/20 °C, 30 °C/25 °C, 35 °C/25 °C, 40 °C/25 °C and 45 °C/25 °C) under two watering conditions [adequate water supply (HW): 80 ± 5% FC (field capacity); low water supply (LW): 40 ± 5% FC] by a pot experiment. The increased temperature (above to 35 °C) markedly aggravated the damage on biomass accumulation and membrane integrity of yellow-horn seedlings under the LW. The accumulation of soluble sugars and proteins exhibited a growing trend as the temperature increased from 25 to 40 °C, which declined when the temperature was higher than 40 °C except for the soluble protein accumulation under HW. In addition, captured responsive characteristics of the gas-exchange parameters and chlorophyll fluorescence have indicated that the combinations of high temperature (above to 35 °C) and LW induced significant decrease in photosynthetic activities of yellow-horn seedlings. All these results showed that the hot stress significantly aggravated the drought damage on yellow-horn plant growth, especially when the temperature increased above 35 °C under drought stress.
