China-Pakistan relations have been renewed for a long time, especially after the “Belt and Road” initiative and the “China-Pakistan Economic Corridor” were put forward, the cooperation between the two countries has continued to deepen and become more solid. “People's Daily” is best at grasping the situation at home and abroad, and it can also reflect the will of the country, constantly weighing between “morality” and “interest”. Its reports on Pakistan are representative among domestic media. Reports show an irregular trend, with fluctuations and declines. There are various types of reports, but they are mainly news, with the layout at the front. The length is relatively long, and the sources of news are more authoritative. In terms of content, the main body of the report is clear, and the leader’s news accounts for a large proportion. China-Pakistan economic cooperation and the China-Pakistan Economic Corridor are the main ones, and positive reports are mainly used. There are more neutral and negative reports in social news. In the cultural field, education exchanges and Youth exchanges are the main focus, and the military field is mainly military cooperation and counter-terrorism. Relevant reporting can also increase the amount of in-depth reporting, provide diversity information, and focus more on cultural reporting.
Scale Dependence of Dislocation Patterns
Yang, Wei,Wu, Xiaoyi,Yang, Qiang 대한금속재료학회(대한금속학회) 1998 METALS AND MATERIALS International Vol.4 No.4
Dislocation patterns result in the scale dependence in the plastic deformation of polycrystalline metals. The present work explores this issue from two aspects: (1) a configuration entropy model for two-level dislocation arrangements; and (2) a dislocation network model incorporating a cell size.
Optimum Design of the Interdigitated CB Structure
qiang, Yang-Hong,bi, Chen-Xing The Institute of Electronics and Information Engin 2002 Journal of semiconductor technology and science Vol.2 No.3
Some measures are provided for the optimum design of specific on-resistance $R_{on}$ and breakdown-voltage $V_B$ of interdigitated CB (Composite Buffer) MOSFET, including introducing opposite type impurity into the P region near the $N_+$contact, separating P region from N region with an oxide film, and a groove in the N region near the $P_+$ contact. The new relationship between the $R_{on}$ and $V_B$, which proved by numerical device simulation, are more exact and minute than the qualitative results before.
Research on the Relation between Transformer Oil Flow Electrification and Electrostatic Current
Qiang Fu,Rui Wang,Pinguo Zou,Zhao Li,Yang Yang,Xuejun Xie 대한전기학회 2015 Journal of Electrical Engineering & Technology Vol.10 No.2
In order to study and obtain the mathematical relation between the electrification degree of transformer oil flow and the electrostatic current, a small amount of data about the electrification degree of oil flow and the corresponding electrostatic current is studied by linear regression method and grey model method. The results show that the linear correlation between the electrification degree and the electrostatic current was not good, and the relation between the electrification degree of oil flow and electrostatic current (i) could be expressed as ρ<SUP>(0)</SUP> =0.2049 i<SUP>(0)</SUP> +169.4419 according to grey model GM (0, 2) when the electrification degree of oil flow is represented by the charge number generated from transformer oil per unit volume, namely the charge density (ρ).
Research on Remote Sensing Image Fusion Algorithm Based on Compressed Sensing
Qiang Yang,Hua Jun Wang,Xuegang Luo 보안공학연구지원센터 2015 International Journal of Hybrid Information Techno Vol.8 No.5
The traditional image fusion algorithm completed the fusion based on all pixel information. The time and space requirements are higher. The improved fusion algorithm used the theory of compressed sensing (CS) for the processing of remote sensing image fusion. Firstly, the source images using wavelet transform for sparse representation, then, the improved fusion algorithm used the observation matrix for image dimension measurement, and completed the image fusion in CS domain. Finally, the algorithm used the improved OMP algorithm to reconstruct the fused image. The improved fusion algorithm is only applied with a few measurement data of the compressed sensing, and overcomed the shortcomings of traditional pixel level fusion, the fusion algorithm achieved good experimental data.

Image super resolution reconstruction has important significance in remote sensing image feature extraction and classification etc.. Because the remote sensing image size is larger, it is difficult to super resolution reconstruction using multiple images, the compressed sensing (CS) theory was introduced into the super-resolution reconstruction. Algorithm designed the low pass filter to reduce the sample correlation matrix and wavelet, at the same time, the algorithm selects the partial Hadamard-matrix as the measurement matrix, it has faster reconstruction speed and low storage requirements, which ensure that the image reconstruction keep with the RIP criterion of compressed sensing theory . Finally, this paper realizes the remote sensing image super resolution reconstruction through the improved iterative algorithm. Experiments show that the reconstructed images of the PSNR value has increased, the reconstructed image has a better visual effect.
A cotorsion pair induced by the class of Gorenstein $(m,n)$-flat modules
Qiang Yang 대한수학회 2024 대한수학회보 Vol.61 No.1
In this paper, we introduce the notion of Gorenstein $(m,n)$-flat modules as an extension of $(m,n)$-flat left $R$-modules over a ring $R$, where $m$ and $n$ are two fixed positive integers. We demonstrate that the class of all Gorenstein $(m,n)$-flat modules forms a Kaplansky class and establish that ($\mathcal{GF}_{m,n}(R)$,$\mathcal{GC}_{m,n}(R)$) constitutes a hereditary perfect cotorsion pair (where $\mathcal{GF}_{m,n}(R)$ denotes the class of Gorenstein $(m,n)$-flat modules and $\mathcal{GC}_{m,n}(R)$ refers to the class of Gorenstein $(m,n)$-cotorsion modules) over slightly $(m,n)$-coherent rings.

A series of novel artemisinin derivatives were synthesized from artemisinin and different anilines. All compounds were obtained as β-isomers. The target compounds were evaluated for inhibition activity against Plasmodium falciparum falcipain-2 in vitro, and most of them exhibited potent inhibition in the low micromolar range and proved to be new types of falcipain-2 inhibitors.
