Game Simulation Analysis of Radical Innovation Processes of High-tech Enterprises based on WoO-EGT Model

An analysis of the evolution law of radical innovation process (RIP) and an identification of the RIP’s influencing factors, particularly to solve the low success rates of the radical innovation of high-tech enterprises, is the focus of this study. The dynamic evolution of RIP can be explained from the perspective of market timing of innovation processes. Moreover, the key influencing factors and the impact mechanism of the process of evolution need to be identified. The window of opportunity-evolutionary game theory (WoO-EGT) model of RIP, which was built by combining WoO and EGT, was used to analyze the dynamic evolutions of the RIPs of existing and new high-tech enterprises. The three categories of RIP evolution when WoO was opened—only locking technology, only breakthrough technology, and coexistence of locking and breakthrough technologies—were determined and verified. Then, the impact mechanisms of the returns and initial proportion of breakthrough technologies on RIP evolution were dynamically and numerically simulated by Matlab. Results show that WoO is the best time for enterprises to implement RIP, and the three game results of RIP evolution of high-tech enterprises under WoO are only locking technology, only breakthrough technology, and both locking and breakthrough technologies, which occupy certain proportions in the market. Moreover, the returns of breakthrough technology play a decisive role in the evolution results of RIP, and the initial proportion of breakthrough technology affects the evolution speed of RIP. According to the research, the WoO-EGT model built in this study is feasible in dynamically analyzing the RIPs. The WoO-EGT model can help overcome the deficiencies of the static model of RIP and provide new decision-making ideas and methods for analyzing the RIPs of high-tech enterprises, thus contributing to the improvement of the success rates of radical innovation

On-chip three-dimensional high-Q microcavities fabricated by femtosecond laser direct writing

We report on the fabrication of three-dimensional (3D) high-Q whispering gallery microcavities on a fused silica chip by femtosecond laser microfabriction, enabled by the 3D nature of femtosecond laser direct writing. The processing mainly consists of formation of freestanding microdisks by femtosecond laser direct writing and subsequent wet chemical etching. CO2 laser annealing is followed to smooth the microcavity surface. Microcavities with arbitrary tilting angle, lateral and vertical positioning are demonstrated, and the quality (Q)-factor of a typical microcavity is measured to be up to 1.07x10^6, which is currently limited by the low spatial resolution of motion stage used during the laser patterning and can be improved with motion stages of higher resolutions.Comment: 17 pages, 3 figure

Group Innovation Ability of Agricultural Technological Innovation Strategic Alliance

Agricultural technological innovation strategic alliance, as an important form of strategic alliance, has steadily strengthened the collaborative management among organizations and raised competitive power with the backing of improved group innovation ability.

Studies of Electroless Copper Plating on Poplar Veneer

Copper coating was deposited on poplar veneer using different relative concentrations of plating solution. The coating structure, thickness, crystal structure, surface resistivity, contact angle, surface free energy, and electromagnetic shielding effectiveness were investigated. The surface morphology and thickness were observed using scanning electron microscopy, and the crystal structure was analyzed using X-ray diffraction. Increasing the relative concentration of plating solution resulted in a uniform and dense coating structure, and the thickness notably increased. In addition, the lateral direction resistivity was two times greater than the longitudinal direction resistivity, and the surface wettability changed from hydrophilic to hydrophobic, which led to a decline in surface free energy. Electromagnetic shielding effectiveness reached 62 dB in the frequency range of 10 kHz to 1.5 GHz. The electroless plating copper veneer was optimal when the solution contained 80 g/L of CuSO4·5H2O, 20 g/L of C4O6H4KNa, 40 g/L of EDTA-2Na, and 40 mL/L of HCHO 40 mL/L

Identification of a New Badnavirus in the Chinaberry (<i>Melia azedarach</i>) Tree and Establishment of a LAMP-LFD Assay for Its Rapid and Visual Detection

The Chinaberry tree, a member of the Meliaceae family, is cultivated in China for use in traditional medicines. In 2020, Chinaberry trees with leaf deformation symptoms were found in Hangzhou, Zhejiang province, China. In order to identify possible pathogenic viruses, a symptomatic sample was subjected to deep sequencing of small interfering RNAs. Assembly of the resulting sequences led to the identification of a novel badnavirus, provisionally designated Chinaberry tree badnavirus 1 (ChTBV1). With the recent development of China’s seedling industry and increasing online shopping platforms, the risk of tree virus transmission has increased substantially. Therefore, it is important to detect the occurrence of ChTBV1 to ensure the safety of the Chinaberry tree seedling industry. Here, we describe the development and validation of a sensitive and robust method relying on a loop-mediated isothermal amplification (LAMP) assay, targeting a 197 nt region, to detect ChTBV1 from Chinaberry tree leaves. The LAMP assay was also adapted for rapid visualization of results by a lateral flow dipstick chromatographic detection method

Influence of Superstructure Pouring Concrete Volume Deviation on Bridge Performance: A Case Study

Due to factors such as casting, mold making, and construction errors, the actual size of the bridge structure will inevitably deviate from the designed size and dimension, and the amount of deviation between the two volumes is generally random and the location of the deviation is not fixed. However, this phenomenon that occurs in the actual practice has not been paid enough attention within existing studies. From a theoretical point of view, the apparent size of concrete will directly affect the cross-sectional stiffness, especially for statically indeterminate structures. This effect will be further reflected in the internal force and stress distribution of the structure. In addition, the variation of the poured volume of the bridge superstructure can also influence the dead-load effect of the bridge structure. Therefore, the influence of pouring concrete volume deviation (PCVD) on the cross-sectional stiffness of large-span continuous reinforced concrete rigid-frame (CRCR) bridges was first stressed and investigated in this paper. Field data of PCVD were monitored by measuring demolished sections with tools that ensure accuracy, and a sensitivity analysis was conducted to analyze the effect of PCVD on the cross-sectional stiffness at different locations. Statistical analysis of the measured data concluded that PCVD has a significant influence on the internal-force distribution and structural stiffness of the bridge, up to 30%. Finally, a theoretical method that considers the influence of PCVD was proposed based on the field monitoring data and the statistical analysis results

2008), ‘Internationalization and Technological Catching Up of Emerging Multinationals: A Case Study of China’s Haier Group’, UNU-Merit Working Paper

A number of firms from China and India have in recent years been demonstrating their ability to face up to the challenges of globalization by internationalizing their operations. In this article we carry out a case study of China&apos;s Haier Group followed by a comparison of its growth and internationalization with those of India&apos;s Tata Group. We examine several aspects of their internationalization, such as the mode of internationalization and the choice of overseas destinations. The study further explores the importance of, among others, conglomerate structure, prior experience, the state, and entrepreneurship in the internationalization of the two groups
