The history of the cosmological reionization is still unclear. Two ionizing sources, stars and QSOs, are believed to play important roles during this epoch. Besides the 21 cm signals, the infrared emission from PopⅢ stars and X-ray photons from QSOs can be powerful probes of the reionization. Here we present a cross-correlation study of the 21 cm, infrared and X-ray backgrounds. The advantage of doing such crosscorrelations is that we could highlight the correlated signals and eliminate irrelevant foregrounds. We develop a shell model to describe the 21 cm signals and find that PopIII stars can provide higher 21 cm signals than QSOs. Using the ROSAT data for X-ray and AKARI data for infrared, we predict various cross power spectra analytically and discuss prospects for detecting these cross-correlation signals in future low frequency radio surveys. We find that, although these cross-correlational signals have distinct features, so far, they have been difficult to detect due to the high noise of the soft X-ray and infrared backgrounds given by ROSAT and AKARI.

目的:调查接受牙科全麻(dental general anesthesia,DGA)治疗患儿的牙科治疗状况。方法:选择2017年6月—2019年11月于昆明医科大学附属口腔医院儿童口腔科接受DGA治疗的18岁以下患者,收集患儿基本信息、DGA治疗原因、麻醉及插管方式、诊疗内容、治疗时间及复诊情况。采用SPSS 26.0软件包对数据进行统计学分析。结果:共纳入120例患儿,男性占58.3%,以3~6岁患儿全麻治疗需求最高(85.0%)。恐惧牙科治疗,非药物行为管理无效是低龄儿童选择DGA治疗的首要因素;6岁以上儿童选择DGA最常见的原因为精神智力障碍(38.9%)及患方要求(38.9%)。人均治疗(15.16±3.42)颗牙,每颗牙平均耗时约12.26 min。龋齿充填术、根管治疗术以及乳牙预成冠(包括前牙树脂透明成形冠套和后牙金属预成冠)修复是主要治疗项目。DGA术后1周,98.3%的患儿无不适感。2017—2019年间选择DGA治疗的患者人数呈上升趋势。结论:DGA可快捷、安全、有效解决恐惧牙科治疗、非药物行为管理无效及精神智力障碍儿童的口腔问题,DGA在患者中的接受度呈上升趋势。在经济欠发达地区,需大力推广DGA培训及相关扶持项目,以满足治疗需求。

This paper presents a piezoelectric-metal structure called a drum transducer. An equation for calculating the resonance frequency of the drum transducer is obtained based on thin plate elastic theory of piezoelectric and metal material combined with the Rayleigh-Ritz method. The finite element method (FEM) was used to predict the excitation frequency of the drum transducer. To verify the theoretical analysis, the input impedance characteristic of the drum transducer was measured using an experimental method. The results obtained from theoretical analysis were in very good agreement with those from the FEM and experimental results. The effect of geometrical changes to the thick-walled steel ring of the drum transducer at the first resonance frequency is also described. The calculated results were found to be in good agreement with the FEM results. The results indicate that the first resonance frequency of the drum decreases with the increasing inner diameter of the thick-walled steel ring.

1936年爱尔兰著名诗人叶芝以一件中国清代的青金石山子为灵感,创作了名为Lapis Lazuli的诗,表达了对雕刻背后“东方智慧”的欣赏。然而很少有人注意到这件山子上还刻有一首乾隆皇帝的诗,反映出雕刻所具有的另一重东方叙事。本文以此为线索,回顾了青金石在18世纪中国宫廷中的一段短暂却又独特的物质文化史,以及这种曾经在欧亚大陆文明史上广泛运用的艺术媒材,如何在跨文化的传播过程中激发出了独特的创造力和想象力。
