Based on the functional properties of electrospun cellulose nanofibers(CNF),scientists are showing substantial interest to enhance the aesthetic properties.However,the lower color yield has remained a big challenge due to the higher surface area of nanofi
人们看到的家族对高风险的厌恶不是一种非理性的态度,而是追求长寿的良好商业判断。在我们最近撰写的一系列文章中,我们详细阐述了企业长期战略的一些特点和维度。本文我们来探讨,对于这些拥有企业的家族而言,其家族目标的重要性。这也许是一个相当抽象的话题。但我们知道,在关键决策中,我们必须得有一些正确的准则和方向,而有这样的准则和方向就意味着有目标。
A facile method was developed to prepare carbon dots(CDs)by pyrolysis and etching of coffee residue.The as-prepared CDs show uniform spherical nanoparticles with an average size of 2.3 nm and exhibit excitation-dependent fluorescence emissions.Moreover,CD
针对深度网络模型进行端到端语音去噪时存在对语音底层信息表示能力不足以及网络只采用卷积级联的方式造成参数冗余的问题,提出了一种融合残差机制和注意力机制的生成对抗网络去噪模型(Attention Res-UNetGAN)。模型在波形域对语音进行去噪,其生成网络为U-Net结构,包含下采样层、中间层和上采样层。中间层为改进的嵌套残差模块(Residual-Residual Block,RRB),是由两块基础残差块进行残差拼接而形成的。对称的下采样层和上采样层之间采用注意力跳连和直接跳连进行连接。在VCTK(Vo
