现有电力物联网任务调度技术难以满足任务的低时延和实时性要求,且未考虑到电力物联网任务之间的内部依赖性。针对该问题,融合深度强化学习任务卸载模型和Sequence-to-Sequence神经网络,使用有向无环图表示任务及依赖关系,引入ε-贪婪探索机制和优先经验回放来鼓励探索和提高模型训练效率,构建基于深度强化学习的电力物联网任务卸载模型。通过与其他任务卸载算法进行对比,所提模型的任务平均处理时延显著优于其他算法,验证在电力物联网依赖型任务低时延调度方面的优越性。

为了使吉林一号卫星遥感数据得到更好的应用,利用月球为辐射源对吉林一号光谱卫星进行了在轨绝对辐射定标研究,以对实验室定标系数进行改进。考虑到定标系数具有时效性,将观测数据按时间分组后定标,利用ROLO模型计算卫星观测时刻月球辐照度,构建ROLO模型值与卫星观测值之间的关系并进行最小二乘拟合,从而获得19个谱段的两组定标系数。最后,将定标结果与吉林一号场地定标、高分四号卫星和SeaWiFS月球观测数据进行对比验证。结果表明:对月定标结果稳定,两组定标系数线性拟合的不确定度分别为1.72%和1.24%;在光谱形状上,利用月球定标后月球光谱曲线平滑,光谱形状与月球辐射特性一致,与场地定标相比,各波段相对大小在定性上得到极大改善;在绝对辐射值上,定标结果与高分四号卫星月球辐照度平均相对误差为8.1%,与SeaWiFS两个波段的平均误差为0.90%和7.42%。本研究说明月球定标是卫星在轨辐射定标及真实性检验的有效途径。

目的探究妊娠糖尿病患者miR-342-3p和miR-423-5p水平与糖脂代谢以及胰岛素抵抗的相关性。方法选取2020年9月至2022年9月在中国福利会国际和平妇幼保健院诊治的96例妊娠糖尿病患者作为研究组,另选取同期孕检健康孕妇96例为对照组,采用实时荧光定量PCR(qRT-PCR)法检测血清miR-342-3p和miR-423-5p表达;采用Pearson法分析血清miR-342-3p和miR-423-5p相关性以及二者与糖脂代谢及胰岛素抵抗相关指标的相关性;采用Logistic回归分析妊娠糖尿病的影响因素。结果研究组血清miR-342-3p、miR-423-5p、空腹血糖(FBG)、空腹胰岛素(FINS)、总胆固醇(TC)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、胰岛素抵抗指数(HOMA-IR)显著高于对照组(P<0.05),高密度脂蛋白胆固醇(HDL-C)和胰岛β细胞功能指数(HOMA-β)显著低于对照组(P<0.05)。根据Pearson相关性分析得知,血清miR-342-3p和miR-423-5p水平呈正相关(P<0.05),血清miR-342-3p和miR-423-5p水平与FBG、FINS、TC、TG、LDL-C、HOMA-IR呈正相关(P<0.05),与HDL-C和HOMA-β呈负相关(P<0.05)。根据Logistic回归分析得知FBG、FINS、TC、TG、LDL-C、miR-342-3p、miR-423-5p高表达,HDL-C降低是影响妊娠糖尿病的危险因素(P<0.05)。结论妊娠糖尿病患者miR-342-3p和miR-423-5p水平异常升高,二者与糖脂代谢和胰岛素抵抗相关。

In eukaryotic cells, initiation of protein translation is to recruit the ribosome to a specific mRNA, which is generally dependent on the 5＇ cap structure. However, protein translation can also be initiated in a cap-independent manner by using a cis-regulatory element termed the internal ribosome entry site （IRES）. The first experimentally validated IRES was reported in the poliovirus （Pelletier and Sonenberg, 1988）. Then eukaryotic cellular mRNAs were also validated to contain IRES elements.
