In response to the problem of high stubble damage rate during sugarcane harvesting, the interaction between sugarcane stalks and basecutter was analyzed, and a sugarcane stubble basecutting device was designed based on the combination of "sliding cutting and shearing cutting" to improve the cutting quality. The principle of unsupported cutting of traditional disc basecutters and supported cutting of sliding shear combination basecutters was analyzed. The result was shown that supported cutting could effectively reduce the bending resistance and inertia force of stems, thus preventing significant deformation of stems to a certain extent, effectively ensuring the cutting quality of stems, and sliding cutting can effectively reduce cutting resistance. The parameters of the key components of the basecutter were determined by establishing the force model of the stem. The sliding cutting operation is carried out using an equal sliding angle blade curve, and the sliding cutting angles and blade bevel angles were 40 ° and 45 °, respectively. The statics and modal analysis of the basecutter were conducted to prevent insufficient tool strength and resonance between the basecutter and the motor during shearing using ANSYS/Workbench. An optimal combination was achieved to fully meet the performance requirements, in terms of structural strength, where the yield strength of the basecutter was 450-650 MPa, while the maximum stress on the basecutter was 102 MPa, and the maximum displacement was 4.94×10-5m. The excitation frequencies of the cutting and the feeding motors were 0- 6.667 and 0-11.667 Hz, respectively. The modal analysis results show that the excitation frequencies of the two motors were much smaller than the first-order natural frequency of the basecutter (60.89 Hz). Therefore, the smooth operation of indoor experiments was obtained without any resonance. A basecutting test bench was built with adjustable cutting disc rotational speed, feeding speed, and cutting angle. The results of the single-factor test showed that when the cutting angle, cutting disc rotational speed, and feeding speed were 10-15 °, 140-220 r/min, and 1.1-1.7 m/s, respectively, the comprehensive evaluation value y was small and the cutting quality was better. The results of orthogonal experiment analysis of variance showed that each factor had a significant impact on the comprehensive evaluation value y. The range analysis of orthogonal experiments shows that the optimal experimental level is the cutting angle was 15 °, the cutting disc rotational speed was 180r/min, and the feeding speed is 1.4m/s. After experimental verification, the comprehensive evaluation values y were 0.256 and 0.298 at this time, indicated the cutting quality was better. Referring to the DG/T 117-2021 sugarcane harvesting machinery test method, the sugarcane stubble damage rate was inspected. The shear qualification rate was as high as 90.4%, and the stubble damage rate was reduced to below 10%. The operation quality of the sliding shear combined sugarcane basecutter met industry requirements. [ABSTRACT FROM AUTHOR]

Aiming at the problems in the bearing fault diagnosis method, such as low efficiency of data storage, transmission and processing, ‘and large number of model parameters leading to waste of resources and low diagnostic accuracy. Based on the improved stage wise weakly ‘orthogonal matching pursuit (SWOMP) algorithm, in view of the problem of low reconstruction accuracy in the SWOMP algorithm, a sigmoid function and a secondary selection process forthe atomic support set were introduced into the SWOMP algorithm. A real-time fault diagnosis ‘method for bearings based on S-shaped quadratic stage wise weak orthogonal matching pursuit (SQSWOMP) algorithm was proposed. Firstly, the intial dictionary was obtained by partitioning the bearing history data into matrices with sliding shift windows, while the overcomplete dictionary was established with the improved K-SVD algorithm. Then, SQSWOMP algorithm was combined with the trained overcomplete dictionary to reconstruct the real-time vibration signals. Finally, the reconstructed signals were sparsely decomposed by using the feature that the dictionary could effectively decompose the specific state signals, but not the other state signals. The results indicate that the reconstruction accuracy and efficiency of SQSWOMP algorithm are better than other matching and tracking algorithms, which can solve the problem of low reconstruction accuracy of SWOMP algorithm. The accuracy of normal, inner ring, outer ring, and rolling body fault diagnosis are improved by 2.17%, 23.46%, 17.30%, and 18.38% without consuming a lot of storage and transmission resources. The accuracy is better than other methods, which can facilitate real-time fault diagnosis. [ABSTRACT FROM AUTHOR]

To investigate the effect of the expression level of diacylglycerol kinase gamma ( DGKγ) ) in paracancerous tissue on the postoperative prognosis of patients with hepatocellular carcinoma ( HCC) and its clinical value. Methods Related clinical data were collected from 78 HCC patients who were admitted and underwent surgical resection from December 2008 to August 2012 in the Affiliated Cancer Hospital of Zhengzhou University. Quantitative real - time PCR was used to measure the mRNA expression level of DGKγ)' in paracancerous tissue, and then the 78 patients were divided into low expression group ( DGKγ)' < 0. 086 2, LEP group) and high expression group (DGKγ)' O. 086 2, HEP group ) . Basic data and clinical features were compared between the two groups. The t - test and the Mann - Whitney U test we re used for comparison of continuous data, and the chi - square test and the corrected chi - square test were used for comparison of categorical data . Univariate and multivariate Cox regression analyses were used to investigate independent influencing factors for survival and prognosis, and the Kaplan - Meier method was used to analyze the overall survival trends of all patients and the LEP and HEP groups in each subgroup of Barcelona Clinic Liver Cancer ( BCLC) stages. Results The multivariate Cox regression analysis showed that the expression level of DGKγ ( HR = L 9 13, 9 5 % CI: L 111 - 3. 296,P = 0. 019 ), HBsAg (HR = 2. 645, 95 % CI: L 264 - 5. 5 37,P = 0. 010 ), Alb ( HR = 0. 952, 95 % CI:O. 916 - 0. 990, P = 0. 013), BCLC stage ( HR = L 702,95 % CI: 1. 267 - 2. 286, P < 0. 001 ) and tumor size (HR = 1. 083, 95 % CI: L 019 - L 152, P = 0. 011 ) were independent influencing factors for long - term survival of HCC patients; the IBP group had a significantly longer median survival time than the HEP group ( 45. 0 months vs 22. 9 months, P = 0. 002 5). The stratified analysis showed that for BCLC stage A HCC, the LEP group had significantly better long - term survival than the HEP group (P =0. 034 5); for BCLC stage B/C HCC, the LEP group had a longer median survival time than the HEP group ( 16. 5 months vs 10. 8 months), but there was no significant difference in short - and long - term survival between the two groups ( P > 0. 05). Conclusion The expression level of DGKγ in paracancerous tissue may be a new index for predicting and evaluating the long - term survival risk of HCC patients after surgery and has certain value in clinical application.
