模糊控制具有可解释性和容易实现等优点,但是自学习能力较弱,难以有效利用控制过程中积累的大数据。平行控制是一种新型智能控制方法,能有效利用互联网和大数据,实现虚实互动、相互增强的智能控制。新方法将模糊控制与平行控制相互结合,提出了平行模糊控制的定义和框架,并对其可能的应用进行了探讨。平行模糊控制有可能扩展模糊控制的发展方向,也可能成为平行控制的一个新思路,在保证可解释与可信自动控制的基础上,有效利用大数据和基于数据驱动的一些机器学习算法实现自学习的控制。

目的评价术前口服布洛芬的超前镇痛方案对单颗后牙种植体植入术后疼痛的影响, 以期为临床应用提供参考。方法采用多中心、随机、双盲、安慰剂平行对照的试验设计。样本量82例。按照纳排标准收集2022年4月至2024年4月于首都医科大学口腔医学院(40例)、首都医科大学附属北京天坛医院(22例)及首都医科大学附属北京朝阳医院(20例)就诊的要求植入种植体的患者。采用简单随机方法将患者按照1∶1的比例分配至布洛芬组和对照组, 每组各41例。布洛芬组与对照组分别于术前15 min口服300 mg布洛芬缓释胶囊和安慰剂, 并在术后3 d内接受相同的镇痛方案。通过数字评定量表(NRS)统计患者术后30 min、4 h、6 h、8 h、24 h、48 h、72 h的疼痛评分, 并记录术后4～6 d额外镇痛药使用量。结果研究共入组82例患者, 失访脱落7例(对照组4例、布洛芬组3例), 共计75例(对照组37例、布洛芬组38例)患者完成试验, 患者均未发生恶心、呕吐等不良事件。布洛芬组患者术后4、6、8 h的疼痛评分[分别为1.0(0.0, 2.0)、1.0(0.0, 2.0)、1.5(0.0, 3.0)分]均显著低于对照组[分别为2.0(1.0, 3.0)、3.0(1.5, 4.0)、2.0(1.0, 4.0)分](z=-1.99, P=0.047;z=-3.01, P=0.003;z=-2.10, P=0.036)。布洛芬组与对照组分别有18.4%(7/38)和27.0(10/37)的患者于术后4～6天额外服用镇痛药, 差异无统计学意义(χ2=0.79, P=0.373);对照组与布洛芬组术后额外用药量分别为[0.0(0.0, 1.0)粒]与[0.0(0.0, 0.0)粒], 差异无统计学意义(z=-0.78, P=0.439)。结论布洛芬超前镇痛可有效降低患者种植体植入术后疼痛程度, 是一种安全有效的围手术期疼痛管理方案。

为提高环氧涂层在腐蚀环境下的防腐性和持久性,合成一种负载有缓蚀剂苯并三唑(BTA)的苯并三唑@磺化聚苯胺功能化倍半硅氧烷(BTA@SPANI-POSS),随后将BTA@SPANI-POSS与环氧树脂共混得到BTA@SPANI-POSS环氧涂料,最后在Q235碳钢上制备数种复合环氧涂层。通过红外光谱、紫外可见光谱、扫描电子显微镜对BTA@SPANI-POSS的结构、缓蚀性能、表面形貌进行表征,利用接触角测量仪、电化学工作站研究所制备涂层的疏水性能和防腐性能。研究表明,随着SPANI-POSS的添加,涂层沾湿性能降低。电化学阻抗谱(EIS)和塔菲尔极化曲线测试结果表明,与SPANI-POSS环氧涂层相比,负载有BTA的BTA@SPANI-POSS环氧涂层对金属基底具有更高和更持久的保护能力,其中试样EB_(1.5%)的腐蚀电流密度i_(corr)为16.67ոA·cm^(-2),其极化电阻R_(p)为2.467 MΩ·cm^(2),具有较低的腐蚀动态速率。在3.5 wt.%NaCl溶液中浸泡15 d后环氧涂层仍具有良好的防腐蚀效果,其阻抗值z_(0.01Hz)仍保留有第1 d时的26.89%,表现出优异的长期稳定性和防腐性能。归因于SPANI-POSS与BTA之间的协同作用,所制备的BTA@SPANI-POSS环氧涂层在浸泡过程中与碳钢基底发生络合反应,从而起到长时间的保护作用。

Introduction: In Burkina Faso, as in most developing countries, limited access to biological tests forces practitioners to resort very often to probabilistic antibiotic therapy. The objective of this study is to determine the extent of this prescription. Patients and Methods: This was a cross-sectional study with retrospective data collection of patients hospitalized in the infectious diseases department in the period from January 1, 2005 to December 31, 2020. The records of patients who received probabilistic antibiotic therapy were included. Results: During the study period, 330 patients had received probabilistic antibiotic therapy. The majority of patients were male (53%), with a sex ratio of 1.12. The mean age of the patients was 33 years ± 14. The age range of 20 to 40 years was the most represented (42%). Fifteen percent (15%) of patients were living with HIV. The majority of patients were from urban areas (56.4%). Forty-nine percent (49%) of the patients worked in the informal sector. Clinically, the reasons for consultation were dominated by fever, alteration of general condition, neurological disorders, digestive disorders, respiratory signs, urinary signs and diffuse pain. The physical examination showed that 48.1% of the patients had meningeal irritation syndrome, 10% had convulsions and 10% had focal signs, trismus was present in 4% of the patients and facial paralysis in 3%. In the digestive system, hepatomegaly was present in 29% of patients and digestive candidiasis in 31%. Respiratory examination showed crepitus and fluid effusion syndrome in 26.83% and 20.62% of patients respectively. The presumptive diagnosis was dominated by bacterial meningitis, salmonellosis and bronchopneumonia with banal germs. In terms of treatment, the beta-lactam family of drugs was the most prescribed. They were followed by aminoglycosides and fluoroquinolones. The evolution was marked by the death of 50 patients (15%). Conclusion: The most prescribed molecules belong to

为揭示腐蚀性介质输送导致的高压空冷器入口管束的流动腐蚀失效机理,准确预测管束的高风险位置,提出了以传质系数和剪切应力作为空冷器入口管束流动腐蚀的关键表征参数。采用Mixture模型和SST k-ω湍流模型对空冷器入口管束段进行数值模拟,获得了入口管束内传质系数和剪切应力的分布特性。结果表明:空冷器入口配管存在偏流现象,引起管束内流动参数左右不对称。其中,传质系数与剪切应力的最大值重合位置位于a管排位号为a_(13)～a_(14)、a_(34)～a_(35)管束的R_1区域(即z为11.5～26.4mm),为流动腐蚀失效的高风险区域。对比失效案例可知,传质系数、剪切应力分布的最大区域与管束腐蚀泄漏失效的区域基本一致,验证了表征参数和预测方法的准确性。研究成果有望为高压空冷器的耐流动腐蚀优化设计和在役风险检验提供理论支撑。
