习近平总书记在党的二十大报告中提出以中国式现代化全面推进中华民族伟大复兴的目标和任务以来,社会各界对中国式现代化从多维视角进行了深入研究,在不少方面取得一致看法、达成基本共识,但对我国何时、什么背景和条件下进入真正意义上的现代化建设进程,学界仍是见仁见智。通过梳理发展脉络可以看到,党的七届二中全会为中国式现代化理念与设想的提出时期;1953年过渡时期总路线标志着我国现代化建设的正式开始;其后,便是中国式现代化建设的探索与推进过程。廓清中国式现代化的起始,紧扣现代化的内涵和现实条件,从多个层面与视角论述其价值与意义,有助于丰富和完善习近平新时代中国特色社会主义思想,瞄准中国式现代化的目标和任务,全面推动中华民族复兴伟业早日实现。

Visible light communication(VLC) network over optical fiber has become a potential candidate in ultra-high speed indoor wireless communication. To mitigate signal distortion accumulated in optical fiber and VLC channel, we present to utilize support vector machine(SVM) for constellation classification in two kinds of geometrically-shaped 8 QAM(quadrature amplitude modulation) seamless integrated fiber and VLC system. We introduce 4 sub-bands to simulate multi-user. Experimental results show that system performance can be significantly improved, and transmission at-2.5 dB m input optical power under 7%forward error correction(FEC) threshold can be realized employing Circular(7, 1) geometrically-shaped8 QAM and SVM. At overall capacity of 960 Mbps, Q-factor increases by up to 11.5 dB.

We evaluate the impact of temperature on the output behavior of a carbon nanotube field effect transistor （CNFET） based chaotic generator. The sources cause the variations in both current-voltage characteristics of the CNFET device and an overall chaotic circuit is pointed out. To verify the effect of temperature variation on the output dynamics of the chaotic circuit, a simulation is performed by employing the CNFET compact model of Wong et al. in HSPICE with a temperature range from -100℃ to 100℃. The obtained results with time series, frequency spectra, and bifurcation diagram from the simulation demonstrate that temperature plays a significant role in the output dynamics of the CNFET-based chaotic circuit. Thus, temperature-related issues should be taken into account while designing a high-quality chaotic generator with high stability.
