Asphalt pavement inevitably suffers rutting distress induced by repeated loads under high temperatures, which can be effectively alleviated by the modification of asphalt *** paper summarized the asphalt modifiers for enhancing the performance of asphalt pavement at high temperatures in terms of the modifier type, additive amount and improving effect. Then, the anti-rutting performance evaluation methods of asphalt binder were introduced with details, including the ring and ball(R&B) test, the dynamic viscosity test, the zero/low shear viscosity(ZSV/LSV) test, the dynamic shear rheometer(DSR) test,the repeated creep and recovery(RCR) test, and the multiple stress creep and recovery(MSCR) test. Furthermore, the sensitivity of the evaluation method to asphalt modifier was analyzed using the normalization method. It was found that the indicators from the MSCR test could clearly reveal the influence of asphalt modifiers on high temperature performance of asphalt binder. But it still had some limitations affecting the accuracy of evaluation results, such as the number of creep-recovery cycles, the stress level and the recovery time. In addition, according to the rutting resistance improvement ratio(RRIR),the styrene-butadiene-styrene(SBS) modifier performed better in improving the rutting resistance of asphalt binder, compared with other modifiers when added within the usual dosage range.

Erlotinib is an orally administered, highly effective, specific epidermal growth factor receptor tyrosine kinase inhibitor, used to treat non-small cell lung cancer and pancreatic cancer. The traditional synthetic methods for Erlotinib exhibit long reaction time and safety concern. Herein, we describe a novel five-step route for the synthesis of Erlotinib in flow. These five steps comprise etherification, nitration, reduction,addition and cyclization reactions. All steps were optimized and converted to continuous flow process,which drastically reduces the reaction time and considerably improves the process safety as well as the total yield. Enabled by five continuous flow units, Erlotinib is efficiently afforded with an E-factor of 38,an overall yield of 83%, and a total residence time of 25.1 min. Majority steps in this process have been optimized for quantitative conversion, which offers the possibility of telescoping the entire process.

The Sichuan-Xizang Railway is an important part of the railway network in China, and geological disasters, such as mountain floods and landslides, frequently occur in this region. Precipitation is an important cause of these disasters;therefore,accurate simulation of the precipitation in this region is highly important. In this study, the descriptions for uncertain processes in the cloud microphysics scheme are improved;these processes include cloud droplet activation, cloud-rain autoconversion, rain accretion by cloud droplets, and the entrainment-mixing process. In the default scheme, the cloud water content of different sizes corresponds to the same cloud droplet concentration, which is inconsistent with the actual content;this results in excessive cloud droplet size, unreasonable related conversion rates of microphysical process(such as cloud-rain autoconversion), and an overestimation of precipitation. Our new scheme overcomes the problem of excessive cloud droplet size. The processes of cloudrain autoconversion and rain accretion by cloud droplets are similar to the stochastic collection equation, and the mixing mechanism of cloud droplets is more consistent with that occurred during the actual physical process in the cloud. Based on the new and old schemes, multiple precipitation processes in the flood season of 2021 along the Sichuan-Xizang Railway are simulated, and the results are evaluated using ground observations and satellite data. Compared to the default scheme, the new scheme is more suitable for the simulation of cloud physics, reducing the simulation deviation of the liquid water path and droplet radius from 2 times to less than 1 time and significantly alleviating the overestimation of precipitation intensity and range of precipitation center. The average root-mean-square error is reduced by 22%. Our results can provide a scientific reference for improving precipitation forecasting and disaster prevention in this region.

"文本乃治学之本,现实为创新之源"之精义是笃定从文本到现实之路的探索。以陆九渊的"六经注我"之治学精神去熟悉和掌握文献是对的,而"我注六经"则背离了"现实为创新之源"的基本原则。现实性在其展开过程中表明为必然性。马克思之所以因为"两大发现"而创立了科学社会主义,在于他将文献中的社会主义理论置于现实基础之上。新时代中国特色社会主义道路是现实之路。新时代的学术创新即是把马克思主义理论置于中国特色社会主义现实基础之上,为中华民族伟大复兴立德、立功、立言。

The formation of Caosiyao giant porphyry Mo deposit is related to three granitic porphyries: coarse-grained granite porphyry (CG)， fine-grained granite porphyry (FG)， and giant plagioclase phenocryst bearing granite porphyry (PG). It should be noted that high-temperature veins commonly cut through low-temperature veins in this deposit. Intermediate density with high temperatures (>550 ℃) and moderate-low salinities (～10 wt.%) characterizes CG-related initial exsolved fluids. Vapor-rich and brine phases separated from the initial fluid following a continuous decrease in pressure and temperature， inducing molybdenite precipitation. FG-related initial fluids are characterized by high temperatures (>550 ℃) and salinities (>65 wt.%). The mixing of low-salinity fluids led to a rapid decrease in the salinity of FG-related fluid， promoting the deposit of the Mo element. The lead-zinc mineralization is closely related to the FG-related fluid， and the addition of meteoric fluid induced the formation of galena and sphalerite. The ore-forming fluid related to the PG is CO2-rich and accompanied by the addition of mantle-derived He-Ar. The presence of CO2did not contribute to the solubility of Mo， resulting in the absence of a considerable amount of molybdenite.
