Analysis of Current Situation and Prospect of Wind Power Energy Cooperation Between China and Jordan Under “One Belt and One Road” Initiative

The “One Belt and One Road” initiative is a great measure to promote the economic development of countries along the line the “B&R” and realizes common economic prosperity. With the continuous development of global economy, the demand for energy is increasing. The excessive use of traditional fossil fuels has led to environmental degradation. Therefore, it has become a consensus to develop green energy cooperation between countries. Different from traditional fossil energy, wind energy is one of the most available clean energy sources, which does not produce pollution and is cheap and easy to obtain. Thus, it is an ideal clean energy. This paper uses literature and survey methods to analyze and research the development situation of wind power energy resources in Jordan and the development of wind power technology in China. Through the analysis of data and examples, this paper aims to put forward suggestions and prospects for the cooperation between China and Jordan and provides references for other countries

The Subtitle Translation of Wolf Warriors From the Perspective of Multimodal Discourse Analysis

With the rapid advancement of multimedia technology, multimodal discourse analysis has gradually become one of the linguistic research hotspots and it integrates the modalities of other fields such as images, sounds, colors and so on to jointly present the complete meaning of the work. The film subtitles are different from traditional paper texts, and their translation is not only a simple text conversion, but also involves complex factors of the transformation of source language and target language culture. From the perspective of multimodal discourse analysis, this paper studies the subtitle translation of Wolf Warriors by using Professor Zhang Delu’s multimodal theory as a framework from cultural level, context level, content level and expression level to analyze how this theory affects the subtitle translation of the film Wolf Warriors and provides valuable suggestions for other film subtitle translation

Imaging Neural Activity in the Primary Somatosensory Cortex Using Thy1-GCaMP6s Transgenic Mice

The mammalian brain exhibits marked symmetry across the sagittal plane. However, detailed description of neural dynamics in symmetric brain regions in adult mammalian animals remains elusive. In this study, we describe an experimental procedure for measuring calcium dynamics through dual optical windows above bilateral primary somatosensory corticies (S1) in Thy1-GCaMP6s transgenic mice using 2-photon (2P) microscopy. This method enables recordings and quantifications of neural activity in bilateral mouse brain regions one at a time in the same experiment for a prolonged period in vivo. Key aspects of this method, which can be completed within an hour, include minimally invasive surgery procedures for creating dual optical windows, and the use of 2P imaging. Although we only demonstrate the technique in the S1 area, the method can be applied to other regions of the living brain facilitating the elucidation of structural and functional complexities of brain neural networks

Dynamic Bandwidth MCIDS - A Cognitive Solution for MCIDS based UWB Communications

Dynamic bandwidth multicode interleaved direct sequence (MCIDS), an enhanced MCIDS based Ultra-wideband (UWB) application is proposed in this paper, featuring a cognitive transmission bandwidth adaptation without any adverse effect on the data rate. By introducing a specific lowpass filtering and down-sampling into the traditional MCIDS algorithm, this system can decrease the transmission bandwidth into part of its original bandwidth but still be able to recover all the transmitted data from the reduced bandwidth. This solution can efficiently improve the coexistence ability of UWB devices in a cognitive manner without increasing hardware complexity

Spontaneous imbibition behavior in porous media with various hydraulic fracture propagations: A pore-scale perspective

Hydraulic fracturing technology can improve the geologic structure of unconventional oil and gas reservoirs, yielding a complex fracture network resulting from the synergistic action of hydraulic and natural fractures. However, the impact of spontaneous imbibition associated with hydraulic fracture propagation on the reservoir matrix remains poorly understood. In this study, combining the Cahn-Hilliard phase field method with the Navier-Stokes equations, pore-scale modeling was employed to capture the evolution of the oil-water interface during dynamic spontaneous imbibition for hydraulic fracture propagation in a two-end open mode. This pore-scale modeling approach can effectively circumvent the challenges of conducting spontaneous imbibition experiments on specimens partitioned by hydraulic fractures. A direct correlation was established between the pressure difference curve and the morphology of discharged oil phase in the primary hydraulic fracture, providing valuable insights into the distribution of oil phase in spontaneous imbibition. Furthermore, it was shown that secondary hydraulic fracture propagation expands the longitudinal swept area and enhances the utilization of natural fractures in the transverse swept area during spontaneous imbibition. When secondary hydraulic fracture propagation results in the interconnection of upper and lower primary hydraulic fractures, competitive imbibition occurs in the matrix, leading to reduced oil recovery compared to the unconnected models. Our results shed light upon the spontaneous imbibition mechanism in porous media with hydraulic fracture propagation, contributing to the refinement and application of hydraulic fracturing techniques.Document Type: Original articleCited as: Zhou, Y., Guan, W., Zhao, C., Zou, X., He, Z., Zhao, H.
