作为第四次工业革命重要基石,工业互联网将孤立的工业系统转化为连接的网络,是数字产业化的重要拓展方向,工业物联网环境中的异常检测对自动化决策具有重要意义。针对现有大多数方法未能有效地考虑传感器间复杂的未知拓扑关系以及工业物联网时序数据内在的不同尺度模式导致异常检测精度有待提升的问题,提出了一种面向工业物联网时序数据的多尺度时空特征融合无监督异常检测方法MSTSAD,构建了一种新颖的双向时空特征提取模块依次捕获多个时间序列之间的相关性和双向依赖性。设计了多尺度门控时间卷积神经网络自适应地提取时间序列的多尺度时序特征,并引入双仿射实现多尺度时序特征和时空特征的交叉融合,增强模型对原始数据的特征提取。提出了结合对抗训练的变分自编码器来放大异常的重构误差并增强模型对训练数据噪声的抗干扰能力,提高了模型对异常数据的区分能力。在GPW、ECG5000、Occupancy和SWaT四个公开数据集上与五种先进方法进行了对比实验,实验结果表明,MSTSAD的F1.数提升了0.01.~0.047。

Aerobic Oxidation of Alcohols to Aldehydes and Ketones with Recyclable Pd Catalysts on Cross-linked 1.1.-Phenanthroline Polymers

中国细胞生物学学会第八届会员代表大会暨学术大会

作者： ZHAO DONG HONG, JIAN jun HONG, SHI YING GUO, RUN liN YANG, Jim YUAN, CHUAN jun WEN, KAIYA ZHOU, CHAO jun li The Jiangsu Key Laboratory of molecular Medical Biotechnology, college of life Science, nanjing normal university, nanjing, 210097, china

Wnt signaling pathway is essential for development and tumorigenesis, however, this signaling pathway in the progress of hepatocellular carcinoma (HCC) remains fully defined. In this paper, we studied the function of human T-cell transcription factor-4 (TCF4), a key factor of Wnt signaling pathway, on the proliferation of HCC cell line. We showed that the expression of TCF4 mRNA in HCC cell line BEL-7402 was higher than that in immortalized normal liver cell line L02. Blockage of Wnt pathway by A NTCF4, a dominant negative TCF4, could suppress BEL-7402 cells growth and decrease cyclin D1.and c-Myc expression, two of target genes of Wnt pathway. Otherwise, stimulating Wnt pathway by introducing a degradation-resistant β-catenin S37A could increase BEL-7402 cells proliferation. But all the treatments had no effect on L02 cells. Our data indicated that TCF4 might be another key factor in Wnt pathway involved in HCC cells proliferation and TCF4 could be an effective therapeutic target for suppressing the growth of hepatocellular cancers.

关键词： Wnt signaling pathway β-catenin dominant negative TCF4.

工作于临界电流模式下的图腾柱无桥功率因数校正(PFC)电路因其无整流桥损耗、电感体积小、易于实现软开关而得到广泛关注。然而,在输入电压过零点处,工频管之间的换相时刻,电感会与工频管的结电容产生谐振,相应地,电感电流和直流母线电压因此会存在高频振荡。电感电流振荡会加剧输入电流畸变程度,而母线电压上的高频尖峰由于振荡频率高,后级DC-DC变换器难以抑制而传递至负载,导致敏感负载无法正常工作。该文分析线性开关在主动栅极电路中抑制振荡的工作原理,基于线性开关的特性提出三电平驱动方式来抑制图腾柱无桥PFC换相谐振,降低输入电流总谐波畸变率(THD)的同时实现对直流母线的高频尖峰的抑制,在2kW满载工况下,将输入电流THD降低1.,母线电压尖峰高频分量峰值由2.83V减小至0.01.V以下。实验结果表明,该文所提出的三电平驱动方式可以有效抑制临界电流模式图腾柱无桥PFC的换相谐振。

为给强筋冬小麦品种的抗旱性评价和抗旱指标筛选提供理论依据,以黄淮麦区种植的8个强筋小麦品种为材料,在水培条件下设置正常供水(对照)和20%聚乙二醇(PEG-6000)模拟干旱胁迫两个处理,测定了萌发期1.个抗旱相关指标、幼苗期20个抗旱相关指标,计算各指标的抗旱系数,采用主成分分析法和隶属函数法求得综合抗旱能力评价值(D值),基于D值评价萌发期和幼苗期抗旱性;在旱棚池栽条件下,测定了2种水分处理下(适时一次灌溉、雨养)籽粒产量,基于产量抗旱系数评价全生育期抗旱性。结果表明:(1.干旱处理下,8个小麦品种萌发期发芽势、发芽率等1.个抗旱指标显著低于对照,根冠比显著高于对照;幼苗期叶片净光合速率、气孔导度等1.个抗旱指标不同程度地低于对照,胞间CO 2浓度、SOD活性等7个抗旱指标显著高于对照。(2)与适时一次灌溉相比,雨养条件下小麦籽粒产量显著降低,降幅1..70%~28.66%,产量抗旱系数为0.71.~0.81.。(3)8个强筋小麦品种在萌发期和幼苗期抗旱等级不尽相同。藁8901.2个生育时期均表现出抗旱性;科大1.26、郑麦7698和丰德存麦5号在幼苗期表现出抗旱性,在萌发期对干旱敏感;新麦26、郑麦366、周麦32号和周麦36在2个生育时期均对干旱敏感。(4)产量抗旱系数与萌发期D值无显著相关性,但与幼苗期D值呈显著正相关。(5)经逐步回归分析,胞间CO 2浓度、蒸腾速率、CAT活性、脯氨酸含量、最大根长和总根长可作为强筋小麦品种苗期抗旱性鉴定的关键指标。

关键词：强筋小麦抗旱性萌发期幼苗期产量抗旱系数相关性
