To develop an accurate and effective short-term air traffic flow prediction model to improve the efficiency of terminal area management, the arrival traffic flow was chosen as the research subject. Firstly, the ARMA(autoregressive moving average) model was adopted for initial linear prediction of the flow time series. Then, the residual sequence after linear prediction was subjected to non-linear correction using the LSTM(long short term memory) model. To address the issue of decreased prediction accuracy caused by redundant features, the AE (autoencoder) model was used to adaptively compress and optimize the input of weather and traffic flow features for the LSTM model. Finally, a comparative experiment was conducted to validate the accuracy, robustness, and timeliness of the ARMA-AE-LSTM model. Experimental results demonstrate that the proportion of predicted absolute errors within 1. 3 aircraft reaches 75% . The average iteration time of the LSTM model is reduced to 1. 014 seconds. When compared with other commonly used deep learning prediction models, the ARMA-AE-LSTM model improves the RMSE ( root mean square error), MAE (mean absolute error), and R² (r-squared) evaluation metrics by 45. 98% ~ 67. 66%, 48. 56% ~ 67. 35%, and 5. 18% ~ 21. 07%, respectively. Furthermore, the ARMA-AE-LSTM model exhibits better robustness in adverse weather conditions. Thus, it can be concluded that this method enables accurate, effective, and rapid prediction of air traffic flow. [ABSTRACT FROM AUTHOR]

The study aimed to explore the impact of different proportions of probiotic fermented soybean meal on the reproductive performance, lactation performance of sows, and the growth performance of piglets. Forty-eight healthy and similar-sized pregnant sows were selected and randomly divided into four groups, with 12 replicates per group, each replicate consisting of one sow. The control group sows were fed a basal diet, while the fermented soybean meal groups replaced the soybean meal in the basal diet with 5%, 10%, and 15% of probiotic-fermented soybean meal, respectively. A one-week pre-experimental period was followed by a formal experimental period from 90 days of gestation to 21 days postpartum. The results showed that feeding sows with 10% and 15% of probiotic fermented soybean meal increased the number of piglets born, the number of live piglets, and the number of healthy piglets (P<0.05), and reduced the average duration of parturition (P<0.05). The rate of healthy piglets in all groups fed with fermented soybean meal was increased, and the rate of stillbirths was decreased (P<0.05). Compared with the control group, feeding with 10% and 15% of probiotic fermented soybean meal significantly increased the sow's feed intake during the second week and the average feed intake during the entire lactation period (P<0.05), significantly reduced backfat loss (P<0.05), increased milk yield, milk fat percentage, lactose percentage, milk protein percentage, and non-fat solid levels (P<0.05), and reduced the level of milk urea nitrogen (P<0.05). Compared with the control group, the birth weight, weaning number, and individual weight at weaning of piglets in the 10% and 15% probiotic fermented soybean meal groups were all increased (P<0.05), and the diarrhea rate was decreased (P<0.05). The weaning weight and survival rate of piglets in all probiotic fermented soybean meal groups was increased (P<0.05). The study indicates that the addition of an appropriate proportion of probiotic fermented soybean meal to the diet of pregnant sows can improve reproductive performance and milk yield, enhance milk quality, and improve the growth performance and survival rate of piglets. Considering production costs, the optimal addition ratio of probiotic fermented soybean meal is 10%. [ABSTRACT FROM AUTHOR]

Objective: To investigate the Effects of vaginal and open surgery on pelvic floor function, inflammatory stress response and sexual quality of life in patients with uterine benign tumor. Methods: The clinical data of 78 patients with uterine benign tumor from March 2017 to January 2019 were analyzed retrospectively, the patients were divided into group A (n=38, treatment by open surgery) and group B (n=40, treatment by vaginal surgery) according to the different operative plans, the indexes of perioperative period, inflammatory stress indexes [Interleukin-6 (IL-6), C-reactive protein (CRP), Cortisol Cor ], pelvic floor dysfunction, complications and sexual quality of life were compared between the two groups. Results: The time of exhaust, operation, hospitalization and getting out of bed in group B were shorter than that in group A, and the amount of bleeding was less than that in group A (P<0.05). The levels of IL-6, CRP and cor were all increased in two groups, but the level in group B was lower than that in group A (P<0.05). The incidence of pelvic floor dysfunction in group B was 12.50% (5 / 40), lower than 36.84% (14 / 38) in group A (P<0.05). The score of Female sexual function index scale FSFI in the two groups was higher than that before operation, and the score in group B was higher than that in group A (P<0.05). The incidence of postoperative complications in group B was lower than that in group A (P<0.05). Conclusions: Compared with laparotomy, vaginal surgery can effectively improve the perioperative indicators, inflammatory stress response, pelvic floor function and sexual quality of life, and reduce the incidence of complications.
