- Abstract
This paper proposed an accurate online hierarchical warning method of the uplift pressure of the gate dam. Considering the impact of the uplift pressure on the concrete gravity dam safety, the real uplift pressure distribution of the dam foundation was approximated by the measured uplift pressure connecting line of two adjacent points on the transverse monitoring section. The measured uplifting pressure was obtained by calculating the area between the connecting line and the dam foundation line using an embedded system of edge computing. Based on the measured uplift pressure, the vertical normal stress and principal stress at the dam heel and toe were calculated, and the stability safety factors of the anti-sliding and anti-overturning were also computed. The online hierarchical warning of the uplift pressure of the dam was realized by comparing the calculated results with the corresponding requirements. In order to convert daily conditions into standard typical conditions, the stability safety factor of typical working conditions was calculated by mapping the measured uplift pressure to typical control working conditions using GRU (Gate Recurrent Unit), which was a deep learning model with low complexity and was suitable for the embedded system of edge computing. The effectiveness of the proposed method was verified with a practical engineering example. [ABSTRACT FROM AUTHOR]

NORMALIZED difference vegetation index , *RUNOFF , *RAINFALL , *PEARSON correlation (Statistics) , *SEDIMENT transport , *WATERSHEDS - Abstract
Understanding the relationship between hydrological and sediment connectivity under extreme rainfall conditions is of great significance for water and sediment regulation and high-quality development of soil and water conservation in the basin under the new situation of vegetation restoration in the Loess Plateau. In this study, the influence of extreme rainfall and vegetation restoration on water-sediment connectivity and the characterization ability of sediment transport potential was analyzed based on the index of connectivity, the structural sediment connectivity (SCst) improved by topographic location index and vegetation cover factor, the functional hydrological connectivity (HCfn) improved by the cumulative surface runoff depth factor. The results showed that the rainfall and vegetation were the main functional and structural factors affecting hydrological and sediment connectivity, respectively. The mean value of normalized difference vegetation index (NDVI) increased by 0.41 from 2000 to 2020, while the mean value of sediment connectivity decreased by 3.54, with a negative correlation coefficient of −0.93. The spatio-temporal distribution of rainfall was in good agreement with the spatio-temporal distribution of hydrological connectivity, both of which were highly correlated on the monthly scale. When extreme rainfall occurred, rainfall runoff factors played a dominant role and determine hydrological and sediment connectivity. The improved water-sediment connectivity index was well applied to the study of large-scale watershed connectivity in the Loess Plateau. Pearson correlation analysis showed that the functional hydrolodical connectivity had a good correlation with runoff and sediment transport capacity in the basin under the inter-annual and seasonal variation, and could better reflect the phenomenon of runoff and sediment increase in the basin under extreme rainfall. Compared with previous studies in which functional connectivity was calculated by using factors such as rainfall erosivity under annual changes, which could not well characterize the actual sediment transport capacity of the basin, the functional connectivity used in this study had obvious advantages, which would provide a more direct and effective tool for water and sediment management in large basins on the Loess Plateau in the future. The interaction between basin structure and functional connectivity changed significantly with seasons. In dry season, vegetation cover was low, rainfall was low, structural sediment connectivity was high and HCfn was increasing. At this time, SCst had a weak influence on HCfn, and the two showed a high negative correlation. In the wet season, with sufficient rainfall and lush vegetation, the correlation between structure and work connectivity changed with the trend of rainfall. At this time, the SCst was low, which limited the function of HCfn to a certain extent. When encountering extreme rainfall, high-intensity rainfall runoff played a dominant role, and SCst couldn’t significantly affect HCfn, while HCfn changed SCst in turn, and both increased at the same time, showing a strong positive correlation. In the normal water season, vegetation gradually withered due to the weakening of rainfall intensity, SCst increased while HCfn decreased, and the negative correlation between the two was enhanced. In conclusion, the improved water-sediment connectivity index has certain advantages and limitations, which can provide guidance for water and sediment management and ecological construction of large watershed in the Loess Plateau under the changing environment in the new era.

NORMALIZED difference vegetation index , *SOIL conservation , *VEGETATION dynamics , *CARBON sequestration , *ARABLE land , *ECOSYSTEMS , *WATER conservation , *WATER shortages - Abstract
Since 1999, China has implemented the Grain for Green Project(GFGP), which has significantly changed the vegetation coverage status and land use structure of the Loess Plateau. As a result, vegetation coverage and ecological quality have been greatly improved. However, the spatio-temporal trend of the vegetation coverage is very uncertain, while the comprehensive assessment of its ecological effects has been relatively weak. To this end, two vegetation indices, including normalized difference vegetation index(NDVI)and fractional vegetation cover(FVC), were analyzed, and the changes in vegetation coverage and distribution on the Loess Plateau before and after the implementation of GFGP in the past forty years were reviewed. The results show that ① comparing five common data sets that record the dynamic changes of vegetation coverage, it is found that the data sources affect the authenticity of the eco-environmental benefits' evaluation results to a certain extent; ② the overall vegetation coverage of the Loess Plateau has been increasing in a fluctuating manner over the years, whose growth rate has surged due to the implementation of the project; its spatial distribution decreases from southeast to northwest, and is influenced by the ecosystem pattern, land use type, climate change, etc.; ③ with a rise of vegetation coverage, the water and soil conservation, and carbon sequestration capacity of the Loess Plateau ecosystem also gradually make a build-up, both of which are highly coupled with vegetation changes. According to the current situation of eco-environment management and food production level, it is recommended to strengthen the construction of high-standard farmland to alleviate the problem of arable land shortage caused by GFGP. Meanwhile, it is necessary to accelerate the promotion of ecological value transformation and eco-compensation, so that the lucid water and lush mountains can truly become invaluable assets.

In this study, five treatments were conducted to determine effect of humic acid conditioners on the growth traits and quality of Codonopsis pilosula, the treatments were plant growth conditioner farmers are used to applying(CK), pure water (T0), humic acid conditioner I(T1), humic acid conditioner II(T2) and humic acid conditioner I + root-promoting growth conditioner(T3), and comprehensive evaluation was conducted through the membership function method to determine the humic acid conditioner the most most suitable for Codonopsis pilosula. The results showed that after spraying different types of humic acid conditioners, the root length of T3 treatment was the largest, which was significantly increased by 7.73% and 6.83% compared with T0 and T1 treatments. The potassium accumulation of T0 treatment was significantly lower than that of the other treatments, which was 18.13%, 9.18%, 13.03%, and 16.48% lower than that of CK, T1, T2, and T3, respectively. The yield of T1, T2, and T3 treatments was significantly higher yields than that of the T0 treatment, and there was no significant difference in the yield between T3 and CK, the yield under T3 was increased by 19.74% compared with T0. The content of moisture, total ash and extract of Codonopsis pilosula reached the standard of the Chinese Pharmacopoeia(2020 edition). The content of polysaccharide and lobetyolin under T3 was significantly increased by 49.97% and 78.95% compared with CK, respectively, and the value was significantly increased by 25.25% and 30.77% compared with T0, respectively. Humic acid conditioner I + root-promoting growth conditioner had the best effects on increasing the yield and simultaneously improving quality of Codonopsis pilosula by the comprehensive evaluation based on membership function method.

HIGH performance liquid chromatography , *SULFONAMIDES , *ACETONITRILE , *CENTRIFUGATION - Abstract
In order to determine sulfonamides in feed efficiently, five kinds of sulfonamides in feed were determined by high performance liquid chromatography (HPLC). The sample container 100 mL conical flask was changed into 50 mL centrifuge tube by GB/T 19542—2007 method, and the acetonitrile volume of extract was changed from 50 mL to 25 mL. The methodology of the improved method was verified. The range of the method was from 0.1 to 5.0 µg · mL-1, R2 >0.999 9 for five concentrations, positive addition recoveries for four different concentrations ranged from 85.8% to 113.0%, coefficient of variation (RSD) ranged from 0.2% to 7.6%, RSD<15%. The results showed that the method had good linearity, high accuracy, good precision, and met the requirements of methodology. The improved method was convenient for whirling, shaking and centrifugation, and the organic reagent pollution was reduced by reducing the amount of the extract. A more reasonable, convenient and efficient method for the detection of sulfonamides was established, which could be used for the confirmation and detection of illegal addition of sulfonamides in feed.

- Abstract
Objective To examine the heart sound signals of four common congenital heart diseases of ventricular septal defect, atrial septal defect, patent ductus arteriosus and patent foramen with associated pulmonary hypertension and propose a deep learning-based intelligent auscultation algorithm for automatic classification of heart sound signals. Methods The algorithm in this study was based upon digital signal processing technology of converting one-dimensional temporal signal classification into a two-dimensional image classification and further applying deep neural networks for automatic classification of heart sound signals. A total of 941 heart sound data samples collected from Children's Hospital of Zhejiang University School of Medicine were employed for training, validation and testing with a ratio of 8 1 1 for training, validation and testing sets respectively. Additionally, 107 heart sound data samples gathered from a clinical screening environment were collected to validate the effectiveness of intelligent auscultation algorithm in real-world clinical applications. Results In this study, discrete wavelet transformation was utilized to denoise the heart sound signals and there was a significant improvement in model performance. Compared to model without denoising, the denoised model achieved no- table enhancements in accuracy, sensitivity, specificity and F1 score on testing set with improvements of 15. 8%,32.6%,11.1% and 27.3% respectively. Furthermore, the authors compared the performance of several common classification neural network models, including Swin_transform, Vit, Mobilenet, Resenet and Vgg, with their respective F1 scores of 0.905,0.842,0.687,0.814 and 0.864. Finally, using Swin_transform model, tests on the external dataset of 107 cases yielded an accuracy of 0.833, a sensitivity of 0.872 and a specificity of 0. 801. Conclusion This study highlights the significant impact of noise and neural network structure on the performance of automatic classification models for CHD heart sound signals. Through the application of discrete wavelet transform for denoising heart sound signals, a substantial improvement in model performance is observed. Among various common classification neural network models, Swin_transform model exhibits the best classification performance. Additionally, the validation of intelligent auscultation algorithm on an external dataset of 107 cases demonstrates its effectiveness in real-world clinical applications, yielding favorable accuracy, sensitivity and specificity results. In summary, this study demonstrates the promising potential of deep learning-based intelligent auscultation algorithms for automatic classification of CHD heart sound signals. [ABSTRACT FROM AUTHOR]

- Abstract
Bipolar disorder, as a major mental illness, has a high lifetime suicide attempt rate in patients, and suicidal behavior is most likely to occur during depressive episodes. Therefore, in-depth study of its mechanism is essential for prevention, early detection and intervention of suicide. With the development of magnetic resonance imaging (MRI) technology, it has been found that there are abnormalities in the brain structure and function in suicidal patients with bipolar disorder. This article reviews the studies on suicide in bipolar disorder patients by MRI from four aspects: structure, function, structure-function, and central metabolism and cerebral blood flow perfusion, and summarizes the suicide-related changes. This review focuses on distinguishing the brain MRI changes under different mood states and diverse definitions of suicide, aiming to provide reference for further exploration of the pathophysiological mechanism of suicide in bipolar disorder.

- Abstract
BACKGROUND: It has been elucidated that downregulation of nuclear enriched abundant transcript 1 (NEAT1) inhibits the progression of keloid fibroblasts, but the exact mechanism is not fully understood. OBJECTIVE: To investigate the influences of long non-coding RNA nuclear enriched abundant transcript 1 (lncRNA NEAT1) on the proliferation, apoptosis and migration of keloid fibroblasts by regulating the miR-136-5p/ubiquitin-specific protease 4 (USP4) axis. METHODS: Keloid fibroblasts were divided into five groups: si-NC group, control check group, si-NEAT1 group, si-NEAT1+miR-136-5p inhibitor group, and si-NEAT1+inhibitor-NC group. qRT-PCR was performed to measure the expressions of NEAT1 and miR-136-5p; cell counting kit-8 assay and EDU staining were performed to measure cell proliferation; flow cytometry was performed to measure apoptosis; scratch-healing experiment was performed to measure cell migration; western blot assay was performed to measure the protein expressions of USP4, p27, Bax, matrix metalloproteinase-9, α-smooth muscle actin, and type I collagen α1 chain; dual-luciferase assay was performed to examine the relationship of NEAT1 with miR-136-5p as well as the relationship of miR-136-5p with USP4. RESULTS AND CONCLUSION: Compared with the si-NC group, the NEAT1 expression, absorbance value at 450 nm, percentage of EDU positive cells, scratchhealing rate, the protein expressions of USP4, matrix metalloproteinase-9, α-smooth muscle actin, and type I collagen α1 chain decreased in the si-NEAT1 group (P < 0.05), while the expression of miR-136-5p, apoptosis rate, and the protein expressions of p27 and Bax increased (P < 0.05). miR-136-5p inhibitor reversed the effect of silencing NEAT1 on the biological behavior of keloid fibroblasts. There was a targeted regulatory relationship between NEAT1 and miR-136-5p as well as between miR-136-5p and USP4. To conclude, silencing NEAT1 may inhibit the proliferation and migration of keloid fibroblasts and induce apoptosis by regulating the miR-136-5p/USP4 axis.. [ABSTRACT FROM AUTHOR]

从理论和实验两方面对自由空间光通信中常用的两种调制方式进行性能比较分析,旨在找出一种最适合的调制方法抑制大气湍流。在分析Gamma-Gamma信道下OOK(开关键控)和DPSK(差分相移键控)调制的误码率时,将广义超几何方法引入分析。利用Matlab软件搭建系统,通过实验可知,采取相干及平衡探测的DPSK调制时性能要比基于OOK调制的直接探测高出3.21dB;通过对双管平衡探测和单管探测进行实验,结果表明,双管平衡探测的信噪比优于单管探测,约提高21.6dB。因此,基于DPSK平衡探测的相干通信方案具有可行性和优越性。
