研究高血压脑出血手术治疗时间的选择对患者临床疗效及生活质量的影响。选取六盘水市第二人民医院2019年1月—2023年4月收治的40例高血压脑出血患者为研究对象,根据手术治疗时间的不同分为观察组(n=20,发病后立即行手术治疗)与对照组(n=20,受其他原因影响发病后3~6 h内行手术治疗),均行开颅去骨瓣脑内血肿清除手术。比较两组患者治疗效果。结果显示,观察组治疗总有效率高于对照组(P0.05)。治疗后,观察组患者炎症因子水平低于对照组(P<0.05)。研究发现,于高血压脑出血患者发病后立即行手术治疗,能优化临床治疗效果,提高患者生活质量,减轻患者神经缺损程度,降低炎症因子水平,具有临床推广价值。

帕金森病(Parkinson’s disease,PD)患者常伴随认知障碍,严重影响生活质量,因此对帕金森病认知障碍进行超前预测对于临床诊断和干预至关重要。然而,帕金森病受多变量因素(如年龄、性别、病程时间等)的耦合影响,使得认知障碍的超前预测面临严峻挑战。针对帕金森病认知障碍的多变量耦合特性,采用多变量逻辑回归方法,构建了一种新型列线图模型,旨在超前预测帕金森病患者发生认知障碍(cognitive impair‐ment,CI)的风险。首先,应用最小绝对收缩选择算子(least absolute shrinkage and selection operator,LASSO)算法对可能影响患者认知能力的风险因素进行了分析,筛选出相关性高的临床变量。其次,采用多变量逻辑回归方法分析各变量之间的相关性,构建可视化的新型列线图模型,实现对帕金森病认知障碍的风险超前预测。最后,模型性能评估结果表明新型认知障碍预测模型具有良好的准确性、一致性和临床实用性,可显著地提高临床医生的诊断效率。此外,该模型还实现了对同一预测因子不同值的患者数量及分布的可视化对比和分析,能够辅助临床医生根据每位患者的个人风险制定个性化的医疗管理和咨询方案,有助于更早地展开对患者的干预和治疗,具备一定的临床诊断价值。

针对农业大棚用电负荷受农村供电能力、气象因素等的影响,具有强波动性和高非线性的问题,综合大棚短期负荷的气象特征和时序特征,提出了一种基于变分模态分解(variational mode decomposition,VMD)的长短期记忆(long short-term memory,LSTM)网络与卷积神经网络(convolutional neural network,CNN)相融合的VMD-CNN-LSTM的短期负荷预测模型架构。首先,基于VMD方法分解负荷序列,降低负荷波动性;其次,采用CNN方法提取负荷的气象特征,采用LSTM方法提取负荷时序特征,进行负荷分量预测,并将模态分量的预测结果重构;最后,以山东省寿光市农业大棚负荷数据为基础开展仿真实验。结果表明,VMD-CNN-LSTM模型与传统神经网络模型相比,可有效提高农业大棚短期负荷预测的精度。

An approximation method that can lower the computational complexity is presented to reduce the processing time of model predictive control(MPC). The effects of the inaccurate inputs, which are caused by the approximation errors, are reflected as input disturbances and are considered in the design of the controller. The closed-loop system’s stability is guaranteed by a restricted Lyapunov-based constraint and input constraints, ensuring that the states will be eventually bounded at a certain confidence *** to this paper, the effects of the bounded disturbance can be observed via a change in the stability region. The relationship between the regions of the normal and approximated systems is highlighted. The proposed MPC with input disturbance and guaranteed Lyapunov stability is employed in a chemical process,and the simulation results indicate the efficiency of the proposed method.

为了保护环境和节约化石能源,电动汽车正逐步代替传统的内燃机汽车。锂离子电池具有高能量密度、高工作电压、循环性能好、使用温度范围广等特点,近年来被广泛应用于新能源汽车。随着新能源汽车的快速发展,大量动力电池将陆续进入退役期。退役的锂离子电池若处置不当,其电解液、隔膜等有机物会对环境造成严重污染,同时锂离子电池的正极材料中含有大量的的有价金属没有得到充分利用。本文综述了退役锂离子电池正极材料回收处理技术,主要包括电池的预处理、火法冶金和湿法冶金技术,并对比了各种技术的优缺点。在此基础上,展望了未来锂离子电池正极材料回收技术发展方向。

Dear editor,Structure analysis is of crucial importance for achieving reliable system functionality. In many real-world systems, the exact parameters of system model are not available owing to modeling uncertainties or measurement noise, and then structural controllability is pursued in control configuration design. As first proposed by lin in [1],
