新能源汽车动力电池的荷电状态(state—of-charge,SOC)是影响电池能耗以及寿命的关键因素。由于车辆配备的电池多为组合电池,多个单体电池充放电期间会出现储能性能的差异,导致电池内部电力噪声较大,特征难以捕捉,荷电状态监控难度增大。为此提出一种基于离散分布与线性判定相结合的荷电状态监控方法。构建电池电力模型,将不符合线性变化的参数判定为噪声值,通过自适应滤波算法结合噪声时变递推规律,采用修正函数滤除波动较大的噪声值。构建动力电池荷电变动的等效电路模型,计算每一次的充放电过程中模型内电阻、电压、电流以及电容量的线性变化。设计观测函数,将各类电力间的变化与电荷状态结合统一分析,完成电池荷电状态数据的监控。实验结果证明,上述方法获取的电池荷电状态与实测结果基本一致,说明所提方法的监控精准度高,且对电池内部电流变化监控能力也较强。

目的研究长时间亚麻醉浓度异氟醚暴露对新生大鼠脑星形胶质细胞胶质纤维酸性蛋白(glial fibrillary acidic protein,GFAP)和兴奋性氨基酸转运体2(excitatory amino acid transporter2,EAAT2)表达的影响。方法出生后7 d的Wistar大鼠40只,采用随机数字表法随机分为两组(n=20),异氟醚组(Iso)和对照组(Con),分别暴露于1.1%异氟醚(0.5 MAC)和30%氧气与氮气混合气体中维持6 h。在处理后12、24 h、3和7 d时,两组均分别取乳鼠新鲜脑组织(n=5),冰冻组织切片后,用GFAP抗体和EAAT2抗体进行免疫荧光双标染色,测得额叶皮质区和海马区的星形胶质细胞GFAP、GFAP和EAAT2共染区的荧光强度。结果相比Con组额叶皮质区,Iso组GFAP的荧光强度在处理后12、24 h显著降低(P<0.01),而处理后3、7 d两组差异无统计学意义;海马区比较,Iso组GFAP的荧光强度在处理后12、24 h、3 d相比Con组显著下降(P<0.01),处理后7 d差异无统计学意义。Iso组额叶皮质区和海马区GFAP和EAAT2共染区域的荧光强度在处理后12、24 h、3和7 d均显著降低,与Con组差异有统计学意义(P<0.01)。结论 1.1%异氟醚暴露会暂时性减少新生大鼠额叶皮质区和海马区GFAP表达,延迟星形胶质细胞的骨架发育;而对星形胶质细胞EAAT2表达抑制是持续性的,这可能是异氟醚对新生大鼠产生脑毒性的机制之一。

In scenarios where a large amount of data needs to be learned, incremental learning can make full use of old knowledge, significantly reduce the computational cost of the overall learning process, and maintain high performance. In this paper, taking the MaxCut problem as our example, we introduce the idea of incremental learning into quantum computing, and propose a Quantum Proactive Incremental Learning algorithm(QPIL). Instead of a one-off training of quantum circuit, QPIL contains a multi-phase training on gradually-increased subgraphs of all vertices, proactively reducing large-scale problems to smaller ones to solve in steps, providing an efficient solution for MaxCut. Specifically, some vertices and corresponding edges are randomly selected for training to obtain optimized parameters of the quantum circuit at first. Then, in each incremental phase, the remaining vertices and corresponding edges are gradually added and the parameters obtained from the previous phase are reused in the parameter initialization of the current phase. We perform experiments on 120 different small-scale graphs, and it shows that QPIL performs superior to prevalent quantum and classical baselines in terms of approximation ratio(AR), time cost, anti-forgetting, and solving stability. In particular, QPIL's AR surpasses 20% of mainstream quantum baselines, and the time cost is less than 1/5 of them. The idea of QPIL is expected to inspire efficient and high-quality solutions in large-scale Max Cut and other combinatorial optimization problems.

目的研究乙型肝炎病毒(HBV)准种与临床的关系,从HBV准种这个角度阐述相同基因型 HBV导致不同病情的机制。方法选取B基因型HBV感染的慢性携带者血清32份和慢性乙型肝炎重度患者血清28份作为检测对象,采用熔点曲线法比较两组血清波峰数量的差异。结果慢性乙型肝炎重度患者血清的波峰数量明显多于慢性携带者血清(P<0．05),提示前者所携带HBV的准种数量多于后者。结论 HBV准种与乙型肝炎临床表现存在一定关系,在HBV基因型相同时,病情较重的乙型肝炎与HBV准种数量多有关,可在一定程度上解释同一基因型的不同患者出现不同临床表现的现象。

目的总结乳头溢液患者乳管镜下不同数量隆起性病变的临床特征,指导临床对乳头溢液患者的诊断。方法选取2007年7月—2014年12月就诊于中国医科大学第四附属医院的乳头溢液患者515例,患者均行乳管镜检查,且镜下显示存在隆起性病变。回顾性分析乳管镜下不同数量隆起性病变患者的临床特征,包括年龄、乳头溢液情况、溢液孔数、溢液颜色,并观察其乳管镜下隆起性病变所在乳管级别。结果 515例乳头溢液患者中单发隆起性病变454例(88.2%),多发隆起性病变61例(11.8%);年龄≥45岁274例(53.2%),0.05)。单发隆起性病变患者乳管镜下隆起性病变为3级乳管以上者52例(11.5%),多发隆起性病变乳管镜下隆起性病变为3级乳管以上者26例(42.6%);多发隆起性病变患者乳管镜下隆起性病变为3级乳管以上的发生率大于单发隆起性病变,差异有统计学意义(χ2=40.651,P<0.01)。结论临床应关注乳头溢液患者的临床特征,当患者出现双侧乳头溢液、多孔溢液,且乳管镜下隆起性病变为3级以上乳管时,应警惕患者乳管内多发隆起性病变的可能;而患者年龄、乳头溢液颜色不能帮助分辨患者是否出现不同数量乳管内隆起性病变。

对预熟化薏米的鼓风干燥、微波干燥和真空冷冻干燥工艺进行优化,研究干燥方式对薏米营养成分、质构和色泽的影响。结果表明:鼓风干燥最佳工艺条件为温度85℃、干燥时间140 min、物料厚度0.5 cm;微波干燥最佳工艺条件为微波功率539 W、干燥时间5 min、物料厚度3.0 cm;真空冷冻干燥最佳工艺条件为温度-49℃、干燥时间5 h、物料厚度2.5 cm。与原料薏米相比,鼓风干燥和微波干燥制备的预熟化薏米的脂肪和蛋白质含量略有升高,而真空冷冻干燥样品的蛋白质含量有所降低,脂肪含量有所升高。沸水中加热15 min,焖煮5 min后,鼓风干燥和真空冷冻干燥预熟化薏米的硬度明显降低,能与小米共煮同熟;真空冷冻干燥可更好地保持薏米的色泽。
