As most anomaly detection methods generally ignore the impact of video quality fluctuations in actual scenarios on their performance. Firstly, public datasets from the field of video anomaly detection were selected, and a distortion dataset for anomaly detection by artificially introducing common distortions found in surveillance videos through simulation methods was constructed. This paper systematically analyzes the impact of video quality fluctuations on the performance of four classic video anomaly detection algorithms. And the experimental results show that the degradation of surveillance data quality have a negative effect on the effectiveness of the video anomaly detection algorithm. Moreover, the impact of different distortion types and different degrees of distortion on the algorithm is different, as well as, Gaussian noise distortion and over brightness distortion have a greater impact on the algorithm.

By summarizing the relationship between body parts of human beings and the acupoint compatibility of Zangfu diseases, meridian diseases, similar diseases, as well as special acupoint compatibility, it was found that: (i) the matched acupoints for treating different types of diseases show a certain body part-distribution pattern; (ii) acupoints of special acupoint compatibility also display a consistent or corresponding relationship on body parts. The study of body part theory provides a wide range of ideas for acupuncture treatment to select or match acupoints, supports the search for more “effective stimulation” and it can also enrich and improve the existing acupuncture theory system. [ABSTRACT FROM AUTHOR]

Acupoint compatibility is an important part of the acupuncture treatment system, which has a direct impact on clinical efficacy. Based on years of clinical experience and clinical research, the author believes that practitioners treating patients by acupuncture and moxibustion should pay attention to syndrome differentiation of channel theory and acupoint matching along meridians. The acupoint compatibility characteristics of superficial disease and visceral disease are different. Superficial disease is superficial and related to meridian circulation; practitioners should pay attention to the distribution along the meridian and mainly combine local-distal acupoints. When treating visceral diseases, with visceral dysfunction as the main pathogenesis, practitioners should pay attention to surface infusion and combine specific acupoints. Based on the characteristics of acupuncture and moxibustion, selecting the appropriate differentiation and acupoint compatibility method is beneficial to building a clinical practice fit acupuncture treatment system to improve the clinical efficacy of acupuncture.

As a representative external therapy of traditional Chinese medicine, acupuncture is considered a valuable treasure with a history of thousands of years and it has been playing an important role in the process of disease prevention and treatment. In this paper, advices was given in order to improve the reliability of clinical evidence of acupuncture. The author summarized existing contradictions and issues by reviewing the status quo of evidence of acupuncture clinical trials. With the expansion of acupuncture disease spectrum, and emerging of high-quality clinical trials, promoting acupuncture clinical research evidence reliability would serve as the breakthrough point. Currently reliability of evidence in acupuncture clinical research has gained increasing international recognition. However, there remains room for improvement in the setting of sham acupuncture standard, attainment of practical evidence, and translation studies of clinical research result. In the future, it is advised to standardize sham acupuncture, achieve international consensus on operating standards, strengthen real world studies, as well as translate clinical trials result of acupuncture from multiple disciplinary perspectives, to further improve the influence of acupuncture in the process of internationalization.

Objective: To explore the diagnostic valueS of Computed Tomography (CT) combined with Magnetic Resonance (MR) dynamic scanning and the quantitative value of apparent diffusion coefficient (ADC) in the diagnosis of glioma. Methods: From April 2017 to March 2021, 68 cases of patients with intracranial tumors who were diagnosed and treated in our hospital were selected as the research objects. All patients were given CT combined with MR dynamic scans, recorded the ADC value and judged the diagnostic value. Results: There were 38 cases were pathologically diagnosed as glioma (glioma group), and 30 cases of non-glioma (non-glioma group） in the 68 cases. The CT hemorrhage, edema, cross-midline, boundary, unclear features compared between the glioma group and the non-glioma group were differences (P<0.05). The glioma group were mostly showed low signal on T1WI and high signal on T2WI, while the non-glioma group were showed mostly low signal on T1WI or low signal and high signal on T2WI., compared the difference were statistically significant (P<0.05). The MR ADCmax, ADCmedian and ADCmin of the glioma group were lower than those of the non-glioma group (P<0.05). There were 37 cases of glioma were diagnosed by CT combined with MR dynamic scanning, and 31 cases were non-glioma. The sensitivity and specificity of CT combined with MR dynamic scanning in the diagnosis of glioma were 97.4%（37/38) and 100.0%（30/30). Conclusion: CT combined with MR dynamic scanning have good sensitivity and specificity in the diagnosis of glioma. ADC value can effectively reflect the pathological characteristics of the lesion tissue, providing safe and effective clinical imaging method for glioma. [ABSTRACT FROM AUTHOR]

Aiming at the problem that the selection scheme to the electromagnetic-hydraulic braking system(EHYS) is difficult to judge by a single method, an EHYS scheme evaluation method based on rank correlation analysis-fuzzy comprehensive evaluation method was proposed. The rank correlation analysis was applied to determine the index weights of the key indicators, which included braking torque, electromagnetic brake service life, cost performance and installation difficulty. The key index evaluation table was established, the evaluation matrix of each scheme were obtained, the weight of the key indicators and the evaluation matrix of each scheme were fuzzy calculated, the fuzzy comprehensive evaluation model of each scheme were calculated, the evaluation results of each scheme were finally obtained. The results indicate that the best EHYS election scheme can be obtained when the current intensity to the electromagnetic brake coil is 25 A, the air gap between the iron core and the braking disc is 1 mm, the number of coil turns are 810, and the brake disc material is steel material.

Objective To observe the occurrence of acute mountain sickness(AMS), the changes in levels of endothelin-1(ET-1), asymmetric dimethylarginine(ADMA), vascular endothelial growth factor(VEGF) in blood of healthy people after they gradually entered the high altitude area from low altitude, and to investigate the effects of acute exposure at different altitudes on vascular endothelial function in healthy individuals. Methods Forty-five healthy volunteers were recruited from the plains, starting from the plain(400 m above sea level), passing through Xining City(2260 m), Gangcha County(3260 m) and Maduo County(4 270 m). From 400 to 2260 m, it took us 28 hours to arrive by train, and the Lake Louise Score System(LLSS) was used to determine the occurrence of AMS in subjects after staying for 72 h. After 2260 m, we migrated by bus with 10 and 18 h, the LLSS was was used to determine the occurrence of AMS both at 3260 m and 4270 m after staying for 72 h. Venous blood samples were collected from the subjects using vacuum blood collection tubes in the first 24 h before entering the high-altitude area and 72 h after entering different altitudes. The levels of ET-1, ADMA, and VEGF were measured by ELISA.Results All subjects did not develop AMS at different altitudes. As the altitude increased, the serum levels of ET-1, VEGF and ADMA decreased gradually. The serum ET-1, VEGF, and ADMA levels in the subjects at 3 260 and 4 270 m above the altitude were lower than those at the altitude of 400 m. In the 2 260 m area, the serum ET-1, VEGF, and ADMA levels were lower than those at the altitude of 3 260 m(all P<0.05). There was no significant difference in the serum ET-1, VEGF, or ADMA levels between smokers and non-smokers entering different altitudes. When the smokers or non-smokers entered the altitude of 4270 m, the serum levels of ET-1, VEGF, and ADMA were lower than those of the same group at 3260 m(all P<0.05). There was no interaction between smoking and different altitude factors. The effects of different altitudes on ET-1, VEGF and ADMA levels were not related to smoking.Conclusions For healthy people, entering the high altitudes from the plains through gradient elevations helps to reduce the incidence of AMS, during which, the serum ET-1, VEGF, and ADMA levels are decreasing. Changes in serum ET-1, VEGF, and ADMA levels at high altitudes are not associated with smoking. [ABSTRACT FROM AUTHOR]

To precisely control the tillage depth and ensure uniform tillage depth, in this study, measured values of the tillage depth are corrected based on the tillage depth measurement methods and the causes of the measurement errors. In indirect measurement of the tillage depth, the tillage depth is calculated by monitoring the angle of the lifting arm based on the geometric relationship between the position of the suspension mechanism and the angle of the lifting arm. The tillage depth can also be measured directly by monitoring the height cliange of the plow frame relative to die land that has not been tilled. Due to the excellent imitation real-time response of the land wheels and the liigh measurement accuracy of the pull rope sensor that is less susceptible to the intact of the operating environment, with the system made up by the land wheels and the pull rope sensor as the measuring basis, the angular transducer and ultrasonic transducer as the cases, the principles of the tillage depth measurement, both direct and indirect, are analyzed. Besides, the prototype is rebuilt and the tillage and imitation tests are carried out in the Maliindra Tractor Experimental Field (Nanchang, China). The causes of errors in the indirect and direct measurement of tillage depth are explored based on the collected data. As shown by the experiment results, due to the changed measuring basis that might be caused by the wheel sinkage and the tilted tractor body, the indirectly measured tillage depth is always smaller than the target tillage depth, and the deviation becomes larger as the target tillage depth increases; there is a great fluctuation in the values obtained using die direct measurement method, for the sensor cannot conduct accurate sampling because of the factors like soil unevenness, plant residuals, and unit vibration. Based on the causes of the measurement errors, both the direct and indirect measurement results are corrected by the fitting and the Kalman prediction, respectively. As suggested in the modification results, there is an approximate linear correlation between the tillage depth deviation from the indirect measurements and the actual tillage depth (R2=0.986 1), which can effectively reduce the delation based on the fitting formula (before condensation: 3.20, 4.48, 5.61, 6.90 cm; after compensation: 0.14. 0.19, 0.16, 0.17 cm) and ensure that the standard deviation after compensation remains approximately unchanged (before compensation: 0.042, 0.08, 0.032, 0.07 cm; after condensation: 0.047, 0.06, 0.03, 0.082 cm); Kalnian prediction can accurately predict the arrival time of the echo and reduce the noises in the measurements tlirough the state update, which reduces the standard delation of tillage depth (before: 1.60, 1.83. 1.33. 1.83 cm: later: 0.032. 0.010. 0.042, 0.092 cm) and ensures that the average tillage depth (before: 15.06, 20.05, 25.42, 29.33 cm; later: 15.02, 20.08, 25.07, 30.137 cm) and delation (before: 0.064, 0.05, 0.42, 0.65 cm; later: 0.02, 0.084, 0.07, 0.17 cm) are approximately the same. Througli fitting, the variation patterns of the limited obsen-ation data and the tillage depth delations can be explored, and Kalman prediction can minimize the impact of noises on the identification of the system state. As fitting and Kalnian prediction play an effective role in analysing die influence of different parameters on test results and noise reduction, they are applicable to the correction of tillage measurement errors. The method to correct errors in indirect and direct measurements of the tillage depth proposed in tliis study provides a new solution for precisely controlling the electronic suspension and ensuring the seeding depth.
