Traditional machine learning methods for mechanical rate of penetration (ROP) prediction are affected by complex feature extraction and imitations of human understanding, which make the prediction accuracy difficult to meet the on-site demand. Based on this, a new ROP prediction method combining feature extraction and regression prediction was proposed. Firstly, data in drilling engineering were pre-processed by box-plot method and one-hot encoding to eliminate abnormal data and to make discrete characteristic continuous. Secondly, convolutional neural network (CNN) was applied to extracting data features, and channel attention mechanism squeeze-and-excitation network (SENet) was introduced to construct a SE-CNN model, which could adjust the importance of CNN feature channel. Finally, SE-CNN model was compared with CNN model. The results show that the goodness of fit of SE-CNN model is increased by 2. 1%, the mean absolute error and the root mean squared error are decreased by 1. 1% and 1. 5% . SE-CNN model has a better prediction accuracy, and can forecast the ROP of drilling field and provides a scientific reference for increasing the ROP during drilling. [ABSTRACT FROM AUTHOR]

BACKGROUND: In recent years, tranexamic acid has been extensively used to mitigate the substantial blood loss associated with total knee arthroplasty. However, the optimal method of topical application has not yet been established. OBJECTIVE: To evaluate the effectiveness and safety of intraoperative topical application of tranexamic acid combined with physical compression dressing in reducing perioperative blood loss in total knee arthroplasty. METHODS: A retrospective analysis was conducted on 90 patients who underwent total knee arthroplasty at the Honghui Hospital in Xi’an from January 2021 to December 2022. Based on the different topical use methods of tranexamic acid during surgery, patients were divided into three groups, with 30 cases in each group. In the compression dressing group, 2 g of tranexamic acid was placed in the articular cavity, and after packing the wound with gauze and cotton pads, a bandage was used to compress the wound. In the periarticular injection group, 2 g of tranexamic acid was injected into the surrounding tissue of the articular cavity. In the intra-articular injection group, 2 g of tranexamic acid was injected into the articular cavity. The blood loss, operation time, coagulation indicators, inflammatory indicators, and postoperative complications of the three groups were statistically analyzed. RESULTS AND CONCLUSION: (1) In terms of total blood loss, hidden blood loss, and maximum hemoglobin drop, the periarticular injection group had the least amount, and there was no statistically significant difference between the compression dressing group and periarticular injection group (P > 0.05). In terms of intraoperative blood loss, the compression dressing group had the least amount, and there were statistically significant differences compared with the periarticular injection group and intra-articular injection group (P < 0.05). There was no statistically significant difference in operation time among the three groups (P > 0.05). (2) There were no statistically significant differences in coagulation indicators (D-dimer and fibrinogen degradation products) and inflammation indicators (C-reactive protein and erythrocyte sedimentation rate) among the three groups preoperatively and on the first and third days after operation (P > 0.05). (3) There was no statistically significant difference observed among the three groups in terms of slow blood flow in the affected limb, intramuscular venous thrombosis, soft tissue swelling, and incidence of wound complications (P > 0.05). Additionally, no cases of deep vein thrombosis or pulmonary embolism were detected in any of the groups. (4) The topical application of tranexamic acid combined with compression dressing achieves the same effect as a periarticular injection in terms of simplicity of operation and reduced perioperative blood loss. This method also avoids the trauma caused by repeated punctures and does not increase the incidence of postoperative complications, making it a worthwhile option for clinical promotion.

【Objective】Clarifying the structure and function of members of the jojoba HSP20 family（ScHSP20）will provide support for subsequent study.【Method】A systematic analysis was conducted on the ScHSP20 family members in jojoba from structural, phylogenetic, and expression perspectives, and functional analysis of ScHSP20-17 was performed.【Result】The genome of jojoba encompassed 35 HSP20 gene loci, with 8 genes involved in tandem duplications and 5 in segmental duplications. Phylogenetic analysis showed that 35 ScHSP20 clusters into 12 subfamilies, with the highest number of nuclear cytoplasmic subfamilies. Promoter analysis revealed that the majority of ScHSP20 family members possessed cis-acting elements in their promoter regions associated with the responses to hormone and abiotic stress. Transcriptome analysis indicated that the expression levels of some ScHSP20 genes, such as ScHSP20-35 and ScHSP20-17, underwent significant changes during flower and seed development, and genes like ScHSP20-17 and ScHSP20-28 were induced by high temperatures. Subcellular localization analysis showed that the protein encoded by ScHSP20-17 was located in the nucleus, and the overexpression of ScHSP20-17 in Escherichia coli, Saccharomyces cerevisiae, and Nicotiana benthamiana markedly improved their tolerance to high temperature stress.【Conclusion】Some members of the ScHSP20 family are involved in the reproductive development and response of jojoba to abiotic stress.
