Genomic Mutations within the Host Microbiome: Adaptive Evolution or Purifying Selection Review
Jiachao Zhang,Rob Knight,
Engineering 2023, Volume 20, Issue 1, Pages 96-102 doi: 10.1016/j.eng.2021.11.018
Next-generation sequencing technology has transformed our ability to assess the taxonomic composition functions of host-associated microbiota and microbiomes. More human microbiome research projects—particularly those that explore genomic mutations within the microbiome—will be launched in the next decade. This review focuses on the coevolution of microbes within a microbiome, which shapes strain-level diversity both within and between host species. We also explore the correlation between microbial genomic mutations and common metabolic diseases, and the adaptive evolution of pathogens and probiotics during invasion and colonization. Finally, we discuss advances in methods and algorithms for annotating and analyzing microbial genomic mutations.

Strategic Study of CAE 2001, Volume 3, Issue 10, Pages 13-21
An advanced way for controlling desert and sandstorm to protect, recover and expand wetland in north and northwest China is proposed in this paper. The necessary conditions for increasing precipitation in inner continental basin contain mainly three aspects ： westerlies, high mountains for condensation and broad wetland fog as vapour resources . A scheme of project is envisaged, which introduces sea water from Bohai Sea through north Inner Mengolia to Xinjiang. The target of the project is to recover and expand wetland in northwest China. It will produce economis and ecological benefits in the aspects.

Strategic Study of CAE 2003, Volume 5, Issue 1, Pages 48-55
Sustained and deepened aridization process in northwest China in Tertiary and Quaternary period and time of mankind history is discussed in the paper. The rain-creased function of 3 set high mountain condensation systems in northwest China is recognized once more. A sandstorm happened in March 20 this year in Alxa and Ejin(Qi) areas was very strong and arrived in Jappen and Korea. For saving Alxa area from sandstorm a way of introducing sea water from Bohai to Alxa had been proposed. Four problems are replied in this paper. In couclusion, introducing sea water from Bohai Sea to west China is the best way for sustainable development of west China.

It is a basic strategy project for developing west China to introduce sea water from Bohai Sea to west China, comparing to the project on introducing fresh-water from Yangtze River to north China. Some efficacy for Inner Mongolia area and saltization in areas involred in the project were discussed in the paper. As it may take 20 years to get a common view about the project conducting some relaed scientific research and striving to begin earlier the project were suggested.

Xihoumen Bridge is the longest two-span continuous steel box girder suspension bridge in China. Several problems have been encountered due to severe natural environment during the erection of steel box girder at anchor-side of north side span of the bridge. The key technique and construction process of erection and linetype adjustment for the steel box girder are introduced.

Using the FengYun-3C (FY-3C) onboard BeiDou Navigation Satellite System (BDS) and Global Positioning System (GPS) data from 2013 to 2017, this study investigates the performance and contribution of BDS to precise orbit determination (POD) for a low-Earth orbit (LEO). The overlap comparison result indicates that code bias correction of BDS can improve the POD accuracy by 12.4%. The multi-year averaged one-dimensional (1D) root mean square (RMS) of the overlapping orbit differences (OODs) for the GPS-only solution is 2.0, 1.7, and 1.5 cm, respectively, during the 2013, 2015, and 2017 periods. The 1D RMS for the BDS-only solution is 150.9, 115.0, and 47.4 cm, respectively, during the 2013, 2015, and 2017 periods, which is much worse than the GPS-only solution due to the regional system of BDS and the few BDS channels of the FY-3C receiver. For the BDS and GPS combined solution (also known as the GC combined solution), the averaged 1D RMS is 2.5, 2.3, and 1.6 cm, respectively, in 2013, 2015, and 2017, while the GC combined POD presents a significant accuracy improvement after the exclusion of geostationary Earth orbit (GEO) satellites. The main reason for the improvement seen after this exclusion is the unfavorable satellite tracking geometry and poor orbit accuracy of GEO satellites. The accuracy of BDS-only and GC combined solutions have gradually improved from 2013 to 2017, thanks to improvements in the accuracy of International GNSS Service (IGS) orbit and clock products in recent years, especially the availability of a high-frequency satellite clock product (30 s sampling interval) since 2015. Moreover, the GC POD (without GEO) was able to achieve slightly better accuracy than the GPS-only POD in 2017, indicating that the fusion of BDS and GPS observations can improve the accuracy of LEO POD. GC combined POD can significantly improve the reliability of LEO POD, simply due to system redundancy. An increased contribution of BDS to LEO POD can be expected with the launch of more BDS satellites and with further improvements in the accuracy of BDS satellite products in the near future.

The determinations of the rotation phase of quantum gates and mutation probability are the two main issues that restrict the efficiency of quantum genetic algorithm. This paper presents a quantum real coding genetic algorithm（QRGA）. QRGA used an adaptive means to adjust the direction and the size of the rotation angle of quantum rotation gate. In order to ensure the direction of evolution and population diversity，the mutation probability is guided based on the step of frog leaping algorithm which quantified by fuzzy logic. Comparative experimental results show that the algorithm can avoid falling into part optimal solution and astringe to the global optimum solution quickly，which has achieved good results in the running time and performance of the solution.

The structural monitoring system for Xihoumen Bridge is designed and implemented by employing the design method proposed in the paper of Design and Implementation of Structural Monitoring Systems for Xihoumen Bridge (I): Design Method. The general design framework, the design method and implementation of subsystems are examined. The loads and responses of the bridge are analyzed when the structural monitoring system is running and collecting data. The results indicate the structural monitoring system for Xihoumen Bridge is running normally and achieves the desired objectives. The distributed data acquisition and transmission system based on industrial Ethernet is applied and developed well in the bridge structural monitoring system, and can be popularized.

This paper proposes a new method of diagnosing 16.7 MeV high-energy pulsed gamma, named "scattering-absorbing method" . The ratio of the sensitivity of HEG to that of the LEG can reach 106 to 108 by this new method. The sensitivity of 16.7 MeV high-energy gamma ranges from 10-21 to 10-16 C·cm2. It's better than the traditional method which bases on the magnetic analyzer and Cherenkov detector on some aspects.

Estimation of the Impact of Traveler Information Apps on Urban Air Quality Improvement Article

Engineering 2018, Volume 4, Issue 2, Pages 224-229 doi: 10.1016/j.eng.2018.03.003
With the rapid growth of vehicle population and vehicle miles traveled, automobile emission has become a severe issue in the metropolitan cities of China. There are policies that concentrate on the management of emission sources. However, improving the operation of the transportation system through apps on mobile devices, especially navigation apps, may have a unique role in promoting urban air quality. Real-time traveler information can not only help travelers avoid traffic congestion, but also advise them to adjust their departure time, mode, or route, or even to cancel trips. Will such changes in personal travel patterns have a significant impact in decreasing emissions? If so, to what extent will they impact urban air quality? The aim of this study is to determine how urban traffic emission is affected by the use of navigation apps. With this work, we attempt to answer the question of whether the real-time traffic information provided by navigation apps can help to improve urban air quality. Some of these findings may provide references for the formulation of urban traffic and environmental policies.
