The Chinese government adheres to the innovation driven strategy and emphasizes that technological innovation is the strategic support for improving social productivity and comprehensive national strength. This paper discusses the mechanism of technological innovation and regional economic co-evolution, and constructs an index system to assess them based on the principles of synergy and systematics. The authors use a dynamic coupling model to study the law of the cooperative evolution of composite systems and geo-detector methods to reveal the main factors controlling the degree of coordination among them. The results show that the total factor productivity of China's high-tech industry showed a "W"type trend of change from 2006 to 2016, and the other indices exhibited a volatile trend. The total factor productivity, technical efficiency, scale efficiency, pure technical efficiency, and technological progress increased by 37%, 13.3%, 3.9%, 9%, and 20.8%, respectively. There was a significant spatial difference in changes in total factor productivity, forming a core-edge spatial pattern with the middle and upper reaches of the Yangtze River as the center of concentration. Most of China's technological innovation and regional economic complex systems were in a state of interactive development from 2007 to 2016, except in the three northeastern provinces of Zhejiang, Shanghai, and the western part of the country. The degree of coupling of the other provinces showed an increasing trend, and the overall degree of coupling exhibited the spatial pattern of Central > Eastern > Western > Northeastern. The three most influential factors for the degree of coupling of China's provincial complex system were the gross domestic product, efficiency of technological innovation, and expenditure on research and development, whereas the three most important factors affecting the degree of coupling of complex systems were the efficiency of technological innovation, gross domestic product, and number of high-tech enterprises as well as research and development personnel, respectively, in the eastern, central, western, and northeastern regions. Finally, the paper puts forward the suggestions of regional innovation driven coordinated development, technology innovation and regional economic coordinated

Liquid−liquid equilibrium (LLE) data for the ternary system 2,2,3,3,4,4,5,5-octafluoro-1-pentanol + ethanol + water have been reported at (298.15, 308.15, and 318.15) K and 0.1 MPa. The Bachman equation and the Hand equation were used to confirm the reliability of the experimental tie-line data. The experimental data were correlated by the nonrandom two-liquid (NRTL) model, for which the calculated results show good agreement with the ternary LLE data, and the binary interaction parameters of NRTL model were also regressed. Moreover, the distribution coefficients and separation factors in the ternary system were determined by the experimental data.

The present study is a cross-cultural comparison of typical dreams of "being chased" between Tibetan and Han Chinese dreamers. The research is based on 208 interviews combined with responses to a Dream Questionnaire. In total 569 subjects were involved in the research project: 278 Tibetan and 291 Han undergraduate college students. Results show an overall occurrence of a being-chased dream in 90% of the sample population. Moreover, the results also revealed that when being chased in dreams, there is a significant difference on the chasing agents. In addition, more than 95% of all participants experienced negative feelings while in the dream, especially fearful feelings. Also there were significant differences between Tibetan and Han Chinese on the feelings of anger and other (unspecified feelings). For the first reactions in the dreams, Tibetan and Han Chinese showed a significant difference on running away and seeking help. In addition, even though petrified then waking up is the most common final outcome in both groups, there were significant differences on not being caught and petrified then waking up between the two groups. Tibetan and Han Chinese take significantly different approaches, especially on the way of telling others, chanting and praying, self-interpretation, and ignoring and forgetting. The significance of these differences is analyzed in relation to the living environment

Clusters combine the advantages of organic molecules and inorganic nanomaterials, which are promising alternatives for optoelectronic applications. Nonetheless, recently emerged cluster light-emitting diodes require further excited state optimization of cluster emitters, especially to reduce population of the clustercentered triplet quenching state ( 3 CC). Here we report that redox-active ligands enhance reverse intersystem crossing (RISC) of Cu 4 I 4 cluster for triplet-to-singlet conversion, and thermally activated delayed fluorescence (TADF) host can provide an external RISC channel. It indicates that the complementarity between TADF host and cluster in RISC transitions gives rise to 100 % triplet conversion efficiency and complete singlet exciton convergence, rendering 100fold increased singlet radiation rate constant and tenfold decreased triplet non-radiation rate constant. We achieve a photoluminescence quantum yield of 99 % and a record external quantum efficiency of 29.4 %.

Optical neural stimulation in the cochlea has been presented as an alternative technique to the electrical stimulation due to its potential in spatially selectivity enhancement. So far, few studies have selected the near-infrared (NIR) laser in cochlear neural stimulation and limited optical parameter space has been examined. This paper focused on investigating the optical parameter effect on NIR stimulation of auditory neurons, especially under shorter pulse durations. The spiral ganglion neurons in the cochlea of deafened guinea pigs were stimulated with a pulsed 810-nm NIR laser in vivo. The laser radiation was delivered by an optical fiber and irradiated towards the modiolus. Optically evoked auditory brainstem responses (OABRs) with various optical parameters were recorded and investigated. The OABRs could be elicited with the cochlear deafened animals by using the 810-nm laser in a wide pulse duration ranged from 20 to 1000 μs. Results showed that the OABR intensity increased along with the increasing laser radiant exposure of limited range at each specific pulse duration. In addition, for the pulse durations from 20 to 300 μs, the OABR intensity increased monotonically along with the pulse duration broadening. While for pulse durations above 300 μs, the OABR intensity basically kept stable with the increasing pulse duration. The 810-nm NIR laser could be an effective stimulus in evoking the cochlear neuron response. Our experimental data provided evidence to optimize the pulse duration range, and the results suggested that the pulse durations from 20 to 300 μs could be the optimized range in cochlear neural activation with the 810-nm-wavelength laser.
