    This study adopts a corpus-based approach to examine the linguistic features manifested in the English translations of Mao Zedong’s speeches, taking Winston Churchill’s speeches (representative of normalized spoken texts) and the spoken texts in BNC Sampler (representative of original spoken texts) as the reference corpora. By investigating the macro- and micro-linguistic features, it is found that the translated Mao’s speeches (both direct and inverse translations) differ from normalized spoken texts as well as original spoken texts in three aspects: (i) macro-linguistic features, (ii) the use of personal pronouns, (iii) the use of modal verbs. In terms of macro-linguistic features, the average word length of the English translations is higher than that of normalized spoken texts and that of original spoken texts; the standardized type/token ratio and average sentence length of the English translations are higher than those of original spoken texts, but lower than those of normalized spoken texts. Meanwhile, in terms of the use of personal pronouns, the English translations of Mao’s speeches prefer the underuse of the first person singular pronoun I. Furthermore, as far as modal verbs are concerned, the English translations of Mao’s speeches prefer the overuse of must and should on the one hand, and the underuse of shall, could, may, and would on the other hand. Therefore, it can be said that the translated Mao’s speeches exhibit some particular linguistic features, which can not only be differentiated from normalized spoken texts, but also be distinguished from original spoken texts. They are in a middle position in relation to normalized spoken texts as well as original spoken texts. This in-betweenness not only exhibits Mao’s creative and idiosyncratic language use, but also reflects the influence of the language transfer from Chinese into English.</p

    Table S1. Temporal clustering of TB incidents monthly in Qinghai, China, 2009–2013. We set the maximum size for temporal scanning to be 18 months, nearly 30% of the total study period, by which the scan result was best to fit the raw time-series data of TB incidents. Fig. S1.

    Effect of particle gradation on the properties of Mg(OH)<sub>2</sub> slurry: viscosity, stability, and rheology

    In this article, multipeak Mg(OH)2 slurries, that is, unimodal, bimodal, and trimodal, were prepared by blending Mg(OH)2 of distinct particle sizes (d50 of 1, 3, 7, 10, and 20 μm). The effects of particle gradation on the properties of Mg(OH)2 slurry, such as viscosity, stability, and rheological behavior, were investigated. Also, the packing efficiency was analyzed by the compartment packing model. The results revealed that viscosity and stability decrease with particle size or larger particle mixing in unimodal and bimodal schemes. However, trimodal slurry viscosity did not significantly change with particle size ratio. The packing efficiency calculated by the compartment packing model has the opposite trend of viscosity, but this trend is not so strictly consistent in the three-peak gradation scheme. Among the unimodal, bimodal, and trimodal slurries with better viscosity and stability (10, 3 + 10 (3:7), and 1 + 7 + 10 μm (3:1:6)), the trimodal slurry had the lowest viscosity and the highest stability. Its highest yield stress (4.66 ± 0.23 Pa) and flow stress (7.67 ± 0.38 Pa) indicated its structural stability, and it showed good structural recovery capability, reestablishing about 87% in 60 seconds. This might be explained by the fine particles forming a bridge between the coarse particles, resulting in a stable and networked structure.</p

    Vapor Phase Growth of Air-Stable Hybrid Perovskite FAPbBr<sub>3</sub> Single-Crystalline Nanosheets

    Organic–inorganic hybrid perovskites have attracted tremendous attention owing to their fascinating optoelectronic properties. However, their poor air stability seriously hinders practical applications, which becomes more serious with thickness down to the nanoscale. Here we report a one-step vapor phase growth of HC(NH2)2PbBr3 (FAPbBr3) single-crystalline nanosheets of tunable size up to 50 μm and thickness down to 20 nm. The FAPbBr3 nanosheets demonstrate high stability for over months of exposure to air with no degradation in surface roughness and photoluminescence efficiency. Besides, the FAPbBr3 photodetectors exhibit superior overall performance as compared to previous devices based on nonlayered perovskite nanosheets, such as an ultralow dark current of 24 pA, an ultrahigh responsivity of 1033 A/W, an external quantum efficiency over 3000%, a rapid response time around 25 ms, and a high on/off ratio of 104. This work provides a strategy to tackle the challenges of hybrid perovskites toward integrated optoelectronics with requirements of nanoscale thickness, high stability, and excellent performance
