2020年6月4日,国际化学顶级刊物《化学评论》刊发了中国地质大学题为“Artificial Metaphotonics Born Naturally in Two Dimensions (自然孕育于二维材料中的人工超光子学)”的综述性论文。该文第一作者为中国地质大学材料与化学学院特任教授戴志高,新加坡国立大学仇成伟教授、澳大利亚蒙纳士大学鲍桥梁教授为共同通讯作者。
本文提出了一种弹性波一次散射波场的正演方法——弹性波高斯束Born正演.该方法以线性散射理论为基础,通过Born近似建立起地下散射点处不同波型的反射率同弹性波主分量波场之间的数据映射关系,利用高斯束所包含的走时、振幅和极性信息进行不同波型的局部平面波的合成,进而通过逆倾斜叠加将所合成的局部平面波转化为时空域的多分量地震记录.该方法不但保持了射线类方法高效的优点,还具备了处理多次走时波场的能力,从而...
Born正演是一种常用的地震波场正演模拟方法,也是线性化地震反演的理论基础.在实际应用时,Born正演通常结合常规的地震射线方法进行实现.为了克服常规地震射线方法的弊端,并且保证地震波场的模拟精度和计算效率,本文提出了一种基于高斯束的一阶散射波场Born正演方法.该方法分为两个环节:首先,我们利用高斯束的走时和振幅信息将地下散射点处的反射率映射为地表束中心位置处的局部平面波;然后,我们利用逆倾斜叠...
How Ice In Clouds Is Born(图)     Ice  Clouds  Born       2017/11/24
Something almost magical happens when you put a tray full of sloshing, liquid water into a freezer and it comes out later as a rigid, solid crystal of ice. Chemists at the University of Utah have pull...
Throughout nature, moms engage in a trade-off: Churn out a bevy of offspring and hope for the best, or have fewer kids but invest more in their survival.Trinidadian guppies provide a model example of ...
Background: Early nutritional interventions may modulate health risks in preterm-born infants. Previously, we showed that preterm-born infants fed an isocaloric protein- and mineral-enriched postdisch...

This study was to determine the relationship between estimated breeding value and phenotype information after farrowing when juvenile selection was made in candidate pigs without phenotype information...
Background: Very preterm (<32 wk of gestation) infants are at increased risk of eating difficulties compared with their term-born peers. Little is known about the impact of late and moderately preterm...
Background: Civil wars and wars between states have occurred less frequently since the start of the 21st century, but civil insecurity outside the contexts of official wars continues to plague many pa...
Here, the ability of Pediococcus pentosaceus and Pediococcus acidilactici to utilise potato tuber juice for cell synthesis without an external nutrient supplement was investigated, and the influence o...
We investigate the possibility that the amplitude of quantum wave can have a deeper physical meaning other than the probabilistic interpretation base on Born’s postulate. We find that the probabilisti...
Observational studies suggested that breastfeeding benefits the visual development of preterm children, which has been attributed to the presence of docosahexaenoic acid (DHA) in breast milk but no...
Utilizing the 5% Public Use Micro Data Sample (PUMS) from the 2000 Census of Population and 2000-2006 waves of the National Health Interview Survey (NHIS), we examine differences in disability, self-r...
Background: Children born preterm are at risk of visual-processing impairments. Several lines of evidence have contributed to the rationale that docosahexaenoic acid (DHA) supplementation of preterm i...
