Despite advances in forecasting and emergency preparedness, weather related disasters continue to cost many lives, to displace populations and to cause wide-spread damage. Therefore, High Impact Weather Project (HIWeather), a 10-year research project (https://***/en/resources/buHetin/hiweather-10-yearresearch- project), was established in 2016 by WM0 (World Meteorology Organization) WWRP (World Weather Research Program: https://***/pages/prog/arep/wwrp/new/wwrp_new_en. html). HIWeather aimed at achieving dramatic improvements in the effectiveness of weather-related hazard warnings, following recent advancement in numerical weather prediction at km-scale and in disaster risk reduction. The implementation plan was developed under the concept of warning chain, which comprises all components and the connections between to a successful weather-hazards warning: observations, weather forecast, hazard forecast, impact forecast, the generation of warnings and decision making (Fig. 1). A successful warning relies on information produced by the meteorological and related physical sciences, thus its effectiveness of delivery depends on applications of social, behavioral and economic sciences. The workshop of WM0 High Impact Weather Project was held in Beijing during 20-22 November of 2018, attracted a diverse and interdisciplinary group of over 70 scientists from 25 countries in the broad field of physical and social science, during which all elements of the warning chain were discussed critically.

Chinese Journal of Astronomy and Astrophysics 2004年第3期4卷 279-283页

作者： V.G.Klochkova GangZhao V.E.panchuk S.V.Ermakov NationalAstronomicalObservatories ChineseAcademyofSciencesBeijing100012 SpecialAstrophysicalObservatoryRussianAcademyofSciences NizhnijArkhyzKarachai-Cherkessia369167Russia

We present an atlas of a group of bright stars in the range of spectral classes F–G and luminosity classes I–V. The spectra were obtained with spectral resolution R ~ 15 000 within spectral region 4500–6620?. Typical spectra of stars with different metallicity [Fe/H] are included. We also show the digital version of the spectral data in FITS format.

High Resolution Spectroscopy of Halo Stars in the Near UV and Blue Region I. Spectra in the Wavelength Region 3550-5000 A

Chinese Journal of Astronomy and Astrophysics 2006年第5期6卷 579-587页

作者： V. G. Klochkova Gang Zhao S. V. Ermakov V. E. panchuk National Astronomical Observatories Chinese Academy of Sciences Beijing 100012 Special Astrophysical Observatory Russian Academy of Sciences Nighnij Arkhyz 369167Karachai-Cherkessia Russia

An atlas of high resolution （R = 60 000） CCD-spectra in the wavelength range 3500-5000A is presented for four objects in metallicity range -3.0 〈 [Fe/H] 〈 -0.6, temperature range 4750 〈 Teff 〈 5900K, and surface gravity range 1.6 〈 Igg 〈 5.0. We describe the calibration of the stellar atmospheric parameters using Alonso＇s formula based on the method of infrared flux and outline the determination of the abundances of a total number of 25 chemical elements. An analysis of the abundance determination errors for different chemical elements is carried out, and a method is provided for the observations and reduction of spectral material. Properties of the method of producing an atlas of spectra and line identifications are described.

We formulated and analyzed a novel nanoformulation of the anticancer drug cisplatin （Cis） with C60 fullerene （C60＋Cis complex） and showed its higher toxicity toward tumor cell lines in vitro when compared to Cis alone. The highest toxicity of the complex was observed in HL-60/adr and HL-60/vinc chemotherapy- resistant human leukemia cell sublines （resistant to Adriamycin and Vinculin, respectively）. We discovered that the action of the C60＋Cis complex is associated with overcoming the drug resistance of the tumor cell lines through observing an increased number of apoptotic cells in the Annexin V/PI assay. Moreover, in vivo assays with Lewis lung carcinoma （LLC） C57BL/6J male mice showed that the C60＋Cis complex increases tumor growth inhibition, when compared to Cis or C60 fullerenes alone. Simultaneously, we conducted a molecular docking study and performed an Ames test. Molecular docking specifies the capability of a C60 fullerene to form van der Waals interactions with potential binding sites on P-glycoprotein （P-gp）, multidrug resistance protein 1 （MRP-1）, and multidrug resistance protein 2 （MRP-2） molecules. The observed phenomenon revealed a possible mechanism to bypass tumor cell drug resistance by the C60＋Cis complex. Additionally, the results of the Ames test show that the formation of such a complex diminishes the Cis mutagenic activity and may reduce the probability of secondary neoplasm formation. In conclusion, the C60＋Cis complex effectively induced tumor cell death in vitro and inhibited tumor growth in vivo, overcoming drug resistance likely by the potential of the C60 fullerene to interact with P-gp, MRP-1, and MRP-2 molecules. Thus, the C60＋Cis complex might be a potential novel chemotherapy modification.
