An Investigation of the Mechanisms of Radiation-Induced Muscle Injury in a Tree Shrew (Tupaia belangeri) Model

Dose-Response (2022)

Pengcheng Zhao Wei Xia Jianglian Wei Yiwei Feng Mao Xie

Animal models suitable for investigating mechanisms behind radiation-induced muscle injury are lacking. We developed a tree shrew model of such injury and investigated pathological changes and mechanisms.Animals were divided into control (n = 5), radiation-induced acute injury (n = 5), and radiation-induced chronic injury (n = 5) groups. Tensor veli palatini (TVP) muscles of acute injury and chronic injury groups were dissected under a microscope at 1 and 24 weeks after radiation therapy, respectively. TVP muscles were stained with HE and Masson to visualize pathological changes. ELISA was performed to measure oxidative injury. RT-qPCR and immunohistochemical staining was performed to measure expression levels of miR-206 and histone deacetylase 4 (HDAC4).Compared to the control group, acute injury group showed a significant decrease in miR-206 expression (.061 ± .38, P < .05) and a significant increase in HDAC4 expression (37.05 ± 20.68, P < .05). Chronic injury group showed a significant decrease in miR-206 expression (.23 ± .19, P < .05) and a significant increase in HDAC4 expression (9.66 ± 6.12, P < .05).A tree shrew model of radiation-induced muscle injury was established by exposing TVP muscle region to radiation of 20-Gy. Experimental results indicated that injury caused by radiation persisted despite gradual healing of the TVP muscle and miR-206 regulatory pathway plays a key role in regulating radiation-induced muscle injury.

RIS-Aided Next-Generation High-Speed Train Communications: Challenges, Solutions, and Future Directions

IEEE Wireless Communications (2021)

Jiayi Zhang Heng Liu Qingqing Wu Jin Yu Yuanbin Chen

High-speed train (HST) communication is a very challenging scenario in wireless communication systems due to its fast time-varying channels and significant penetration loss. Thanks to its low cost and smart channel reconfiguration ability, the reconfigurable intelligent surface (RIS) has been proposed as a promising technology to solve the aforementioned challenges cost effectively and achieve high spectral and energy efficiency in the next-generation HST communication systems. In this article, we first provide a novel RIS-aided HST wireless communication paradigm, including its main challenges and application scenarios. Furthermore, practical solutions are provided to realize efficient signal processing and resource management in the considered system. Finally, promising research directions of RIS-aided HST communication systems are pointed out to inspire further investigation in future work.

Dust concentration estimation of underground working face based on dark channel prior

IOP Conference Series Materials Science and Engineering (2019)

Dandan Liu Quan Ma Dewen Li Jie Wang Heng Liu

Abstract In this paper, combined with video monitoring system for each working face under the mine, distance measurement system under the mine and Matlab software, real-time monitoring, analysis and calculation of dust concentration under the mine are carried out. Firstly, the image of dust degradation was obtained according to the video monitoring system in the underground dust environment, and the transmission chart with block effect was obtained. Secondly, the obtained transmission figure is processed by Matlab to obtain the corresponding transmission of each pixel in the dust image. Then according to the dust dispersion measurement system to calculate the extinction coefficient, according to the distance measurement system measured the length of the radiation channel distance;Finally, according to the established dust image degradation model, the dust concentration change process and dust mass concentration at each moment and point can be obtained from the extinction coefficient, transmission rate and length of radiation channel. The research method in this paper is rapid and can be used for real-time and online continuous detection, so as to obtain the dust mass concentration and dust distribution in the dust environment.

Rotated face detection in color images using radial template (RT)

2003 IEEE International Conference on Acoustics, Speech, and Signal Processing, 2003. Proceedings. (ICASSP '03). (2003)

Heng Liu Shengye Yan Xilin Chen Wen Gao

We propose a face detection algorithm to locate faces rotated in any orientation. Detecting rotated faces is important for a face detection system. First, we present a novel model named radial template (RT) to detect rotated faces. This template is designed to find stable features of center-rotated objects in edge maps. Based on skin detection and edge extraction, our method searches for face-like areas and gets their orientations by RT searching. Then the candidates are rotated upright and a frontal face detector is used to determine the existence of faces. A system integrating these techniques is presented. Experimental results show that our algorithm is effective for detecting human faces rotated at any angle with different sizes, lighting conditions and backgrounds.

Moiré interferogram phase extraction: a ridge detection algorithm for continuous wavelet transforms

Applied Optics (2004)

Heng Liu Alexander N. Cartwright Cemal Basaran

We present a procedure using continuous wavelet transforms (CWTs) to extract the phase information from moiré interferograms. The relationship between precise ridge detection of the two-dimensional CWT magnitude map and accurate phase extraction is detailed. A cost function is introduced for the adaptive selection of the ridge, and a computationally inexpensive implementation of the cost function ridge detection algorithm is explored with dynamic programming optimization. The results of the proposed ridge detection algorithm on actual interferograms are illustrated. Moreover, the resulting extracted phase is demonstrated to be smooth and accurate. As a result, the sensitivity of the moiré interferometry method is improved to obtain a pixel-by-pixel in-plane strain distribution map.
