Based on the concept of artificial intelligence (AI) and the summary of existing research methods, this essay reviews the theoretical and empirical research into AI’s impact on industrial distribution, jobs, wages and other aspects in the field of employment. The essay finds that AI technology accelerates job polarization in the labor market and causes wage inequality during this process while taking over some occupations and promoting the flow of labor among different industries. In the long run, the substitution and creation effects will coexist for the long term, and the creation effects will exercise increasingly obvious influence; wage inequality can be compensated by long-term social policies; job polarization will not last for long; and workers’ flow between industries is essentially a result of matching labor skills with task needs after technological changes. More scholars believe that the impact of artificial intelligence on employment in the future is controllable, and the key is in the broad and effective human-computer cooperation facilitated by the improvement of labor’s skill levels through education and training

This paper summarizes the current situation of the university education informatization, cloud computing and the application of big data in education, and preliminarily constructs the big data platform model of university informatization intelligent teaching service of Yunnan University Teacher Education Alliance Based on cloud computing Part of the content of the model is described to provide reference for regional alliance education related research.

In this correspondence, we first establish a strong limit theorem for countable nonhomogeneous Markov chains indexed by a homogeneous tree. As corollaries, we obtain some strong limit theorems for frequencies of occurrence of states and ordered couple of states for this Markov chains. Finally, we prove the strong law of large numbers and the asymptotic equipartition property (AEP) for finite nonhomogeneous Markov chains indexed by a homogeneous tree. Index Terms--Asymptotic equipartition property, homogeneous tree, nonhomogeneous Markov chains.

The mode-locking mechanism of a single-section multi-spatial-mode Fabry-Perot semiconductor laser is analyzed by the additive pulse mode-locking (APM) master equation model. Critical parameters of the equivalent saturable absorber as well as the self-phase modulation are estimated. The mode-locking operation regime in terms of pulse chirp and output power is predicted by the APM model and the prediction is shown to be in good agreement with the experimental results of a 40 GHz, 6.7 ps pulse width mode-locked operation at 1.56 [micro]m. OCIS codes: 140.4050, 140.2020.
