神经机器翻译模型基本都是编码器和解码器结构,在进行编码之前都需要把文字抽象成数学符号,以词向量的形式传入编码器。大多数对词向量内部信息进行处理的方法都需要用到大量的资源进行训练,并不能够简单而快速的提升机器翻译性能。针对此问题,基于Transformer模型,提出了一种利用门控循环单元(gated recurrent unit,GRU)对词向量过滤的技术,直接用训练数据进行操作。首先将词向量和位置向量相加后传入GRU,把GRU对词向量过滤后的输出与词向量进行拼接,然后把拼接后的特征向量经过线性层深度融合在一起,这样得到的词向量就是经过门控单元过滤后的词向量表征,最后再传入编码器和解码器。实验结果表明:在Multi30k和IWSLT2016这2个数据集和不同的模型中,提出的方法都能够使机器翻译的BLEU值得到提升,取得较好的翻译性能。

目的探讨盐酸普拉克索对帕金森患者情绪状况以及认知功能的影响。方法选择2021年1月~2022年12月85例帕金森病患者,数字表法随机分为两组。对照组采用左旋多巴治疗,观察组在对照组基础上联合盐酸普拉克索治疗。比较治疗前后简易精神状态检查表(MMSE)、帕金森病评定量表(UPDRS),汉密尔顿抑郁以及焦虑量表(HAMD)、(HAMA)的结果。结果两组治疗后MMSE评分升高、UPDRS评分降低,且观察组治疗后MMSE评分显著高于对照组,UPDRS评分显著低于对照组(P<0.05);两组治疗后HAMD评分以及HAMA评分均显著降低,且观察组治疗后两评分均显著低于对照组(P<0.05)。结论盐酸普拉克索能够有效缓解帕金森病焦虑、抑郁情绪,提升认知功能,并促进帕金森病临床症状的改善。

The twist angle between two van der Waals coupled monolayers has emerged as a new and powerful degree of freedom for engineering physical properties of semiconductor homo-and *** the interlayer twist has shown prominent effect on electronic and optical properties of transition metal dichalcogenide(TMD)bilayers,it remains unclear how it could be used to manipulate the exciton dynamics,especially exciton-exciton annihilation(EEA)process which is the dominant energy loss channel in TMDs under moderate to high exciton density due to strong Coulomb ***,we show that the twist angle in TMD bilayers can act as an effective knob to control the EEA ***,EEA rate constant increases from 1° twisted WSe_(2) bilayers(0.026 cm^(2)/s)by more than twice to 32° twisted bilayers(0.053 cm2/s)and then drops again in 60° twisted bilayers(0.019 cm^(2)/s).This twist-angle dependence can be attributed to the energy difference between indirect and direct excitons arising from the interlayer *** work opens up the possibility of artificially managing the exciton dynamics in TMD materials for optoelectronic applications via interlayer twist angle.

双目结构光三维成像技术,通过投影结构光获取被测物体高度分布,进而获取物体三维信息,可广泛应用于工业生产、医疗研究等领域。目前应用较多的基于格雷相移法的三维成像技术由于环境光、镜头光学误差等不稳定因素的干扰,依然存在解码错误、匹配不准确等问题。在现有技术基础上,提出了一种改进算法,该算法采用互斥互补格雷码的方式进行投影,利用双向均值化的解码方法解包裹相位,通过掩膜约束的立体匹配方式生成高质量点云数据。经过实验分析和验证,本算法较传统算法相比精度提升了11.49%.,平均点集数量提升了14.82%,证明该算法可以有效抑制光学噪声干扰,提高三维成像的精度。
