Abstract

Background: Bladder cancer (BCa) is a prevalent malignancy characterized by a poor prognosis. Numerous studies have increasingly recognized the role of M2 macrophages in cancer progression. Consequently, our objective is to investigate hub genes in BCa associated with M2 macrophages, assessing their prognostic significance and exploring potential regulatory mechanisms. Methods: We performed a comprehensive bioinformatics analysis using data from urine proteomics, the Gene Expression Omnibus (GEO) database, and The Cancer Genome Atlas (TCGA) database, in conjunction with machine learning methods such as LASSO and SVM to identify intersections of differentially expressed genes (DEGs). Subsequently, the role of hub genes in BCa was validated in vitro and in vivo using CCK-8 assay, wound healing assay, immunofluorescence assay, transwell assay, immunohistochemistry, and xenograft tumor model. Finally, we investigated the correlation between hub genes and M2 macrophage immune infiltration using the TIMER database. Results: Chitinase 3 like 1 (CHI3L1) emerged as a pivotal gene linked to M2 macrophages in BCa. Notably, CHI3L1 was associated with a poor prognosis for BCa, with elevated expression correlating to more advanced histologic and pathologic stages in BCa patients. The findings suggest that inhibiting CHI3L1 can effectively impede the proliferation, migration, and invasion of BCa cells and synergistically increase the inhibitory effect of gemcitabine (GEM) on cell activity. Meanwhile, the downregulation of CHI3L1 was accompanied by inhibition of the PI3K-AKT signaling pathway. Additionally, CHI3L1 demonstrated a significant association with M2 macrophage infiltration in the BCa tumor microenvironment (TME). Conclusions: The present study suggests that CHI3L1 may promote bladder cancer progression through the PI3K-Akt signaling pathway and is associated with M2 macrophage infiltration.

Abstract

Slot-die coating is widely used in the preparation of negative electrodes for lithium batteries. The thickness of the negative electrode has a significant influence on the battery performance and lifespan, and different manufacturers have different requirements for its thickness. In order to reduce the waste caused by trial and error in the electrode preparation process, a prediction model for the negative electrode thickness was established and verified through simulation and experiments. Based on the Landau–Levich film equation and the Ruschak model, a high-precision prediction model was constructed by taking into account the influence of factors', such as temperature and slurry, spreading characteristics on the coating thickness. The minimum coating thickness and its influencing factors were explored. Meanwhile, the simulation analysis of the coating thickness was performed, and the theoretical values of three common process parameters were compared with the simulation results, showing a deviation of only 2.9%. An experiment on predicting the thickness of the negative electrode of lithium batteries was conducted. Thickness measurements were performed on the samples prepared through the experiment and compared with theoretical values. The accuracy rate of this thickness prediction model can reach 98.75%.

Abstract

The development of cisplatin resistance often results in a grim prognosis in advanced or recurrent bladder cancer. However, effective treatment strategies for cisplatin resistance have not been well established. Herein, we found that overactivation of SRC is associated with cisplatin-resistance. SRC activates hexokinase2 which up-regulates glycolysis and especially the pentose phosphate pathway that leading to increased nucleotide synthesis and NADPH production which can neutralize reactive oxygen species (ROS) induced by cisplatin, thereby protecting bladder cancer cells from cisplatin-induced DNA damage. This phenomenon was effectively reversed by knockout of SRC and inhibition of SRC activity by the SRC inhibitor, eCF506. Moreover, we constructed Cell-derived xenograft (CDX) and Patient-derived xenograft (PDX) from cisplatin-resistant bladder cancer patient. eCF506 exhibited excellent anti-tumor effects and effectively enhanced cisplatin-sensitivity. Altogether, our findings demonstrate that targeting SRC is a promising approach to overcome cisplatin-resistance in bladder cancer, and providing new insights for combination therapy in bladder cancer. SRC-mediated reprogramming of energy metabolism towards glycolysis and the pentose phosphate pathway contributes to cisplatin resistance in bladder cancer. [ABSTRACT FROM AUTHOR]

Abstract

To address the issues of low trajectory planning efficiency, high motion impact, and poor operational stability in robotic arms during the automatic loading and unloading of aluminum blocks in coating machinery, a time-optimal trajectory optimization method based on a dynamically adaptive Particle Swarm Optimization (PSO) algorithm is proposed. First, the loading and unloading process of aluminum block components is described, followed by a kinematic analysis of the robotic arm in joint space. Then, the "3-5-3" hybrid polynomial interpolation method is used to fit the robotic arm's motion trajectory and simulate the analysis. Finally, with the robotic arm's operation time as the objective function, the dynamically adaptive PSO algorithm is applied to optimize the trajectory constructed by hybrid polynomial interpolation, achieving time-optimal trajectory planning for aluminum block handling. The results demonstrate that the proposed method successfully reduces the trajectory planning times for condition 1 and condition 2 from 6 s to 3.59 s and 3.14 s, respectively, improving overall efficiency by 40.2% and 47.7%. This confirms the feasibility of the method and significantly enhances the efficiency of automated loading and unloading tasks for aluminum blocks in coating machinery. The proposed method is highly adaptable and well-suited for real-time trajectory optimization of robotic arms. It can also be broadly applied to other robotic systems and manufacturing processes, enhancing operational efficiency and stability. [ABSTRACT FROM AUTHOR]

Abstract

This paper addresses the issue of the high-precision control of substrate tension in an accumulator during the roll-to-roll coating process. First, a coupling model for tension errors in the substrate within the accumulator is established, along with dynamic models for the input–output rollers, carriage, and the thrust model of the ball screw. Based on these models, a simulation model is built in MATLAB/Simulink to analyze the main causes of substrate tension errors in the accumulator under uncontrolled conditions. Next, to tackle the tension errors caused by carriage displacement, a nonlinear proportional–integral–derivative (PID) controller is proposed, and a control strategy for substrate tension in the accumulator is designed. Finally, based on the established simulation model, experiments are conducted using the proposed nonlinear PID controller and the designed tension control strategy, and their performance is compared with that of a classical PID controller. The simulation results show that both the nonlinear PID controller and the classical PID controller, when combined with the proposed tension error control strategy, can reduce tension errors in the accumulator substrate. However, the nonlinear PID controller is more suitable for controlling substrate tension errors in the accumulator. On the one hand, the nonlinear PID controller has better anti-disturbance capability. In the anti-disturbance experiment, under PID control, the substrate tension error remains stable at around −1.6 N, with tension disturbances of ±0.2 N occurring at approximately 185 s and 135 s. On the other hand, the nonlinear PID controller demonstrates better robustness. In the robustness experiment, under the nonlinear PID controller, the substrate tension error fluctuates within the range of 0 to 0.02 N, showing excellent robustness. [ABSTRACT FROM AUTHOR]

Abstract

Aiming to address the problems of uneven brightness and small defects of low contrast on the surface of lithium battery electrode (LBE) coatings, this study proposes a method for detection and identification of coatings defects in LBEs based on an improved Binary Tree Support Vector Machine (BT-SVM). Firstly, adaptive Gamma correction is applied to enhance an image, and an improved Canny algorithm combined with morphological processing is used to accurately detect the defect regions. Secondly, the shape and grayscale features of the defects are extracted from the connected defect areas, and these features are then fused and normalized. Finally, a BT-SVM multi-class classification model is constructed, with the Whale Optimization Algorithm (WOA) employed to assist in hyperparameter tuning. The experimental results show that the proposed method can effectively detect and identify five common types of defects in the coating of LBEs, including scratches, bubbles, metal leakage, particles, and decarbonization, with an average detection accuracy of 94.4% and an average detection time of less than 0.2 s, meeting the real-time detection requirements for online defect inspection. After Whale Optimization, the BT-SVM defect recognition model achieves an average recognition accuracy of 98.7%, significantly enhancing the performance of current defect detection technologies for LBE coatings.

Abstract

Lithium‐rich manganese‐based layered oxides (LRMOs) have been regarded as a promising category of cathode materials due to their high specific capacity on basis of joint anionic(oxygen) /cationic redox chemistry at a high voltage, thus high energy density. The anionic redox play the key and restive roles in LRMOs, contributing the extra capacity, meanwhile being associated with several unfavorable structural and electrochemical issues. This work systematically enumerates the oxygen redox mechanisms, and challenges associated with oxygen‐anion redox in LRMOs, including irreversible transition metal migration, phase transition, and the capacity/voltage decay, etc. The recent progress made in modification of LRMOs with particular emphasis to promoting the reversible oxygen redox reaction and inhibiting the irreversible oxygen release are summarized, followed by an outlook on the future rational design and development of LRMOs. This comprehensive review and perspective are expected to provide insights for the greater utilization of oxygen redox in LRMOs and other related materials. [ABSTRACT FROM AUTHOR]
