AbstractDecades of efforts made by Chinese astronomers have established some basic facilities for astronomy observations, such as the 2.16-m optical telescope, the solar magnetic-field telescope, the 13.7-m millimeter-wave radio telescope etc. One mega-science project, the Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST), intended for astronomical and astrophysical studies requiring wide fields and large samples, has been initiated and funded.To concentrate the efforts on mega-science projects, to operate and open the national astronomical facilities in a more effective way, and to foster the best astronomers and research groups, the National Astronomical Observatories (NAOs) has been coordinated and organizated. Four research centers, jointly sponsored by observatories of the Chinese Academy of Sciences and universities, have been established. Nine principal research fields have received enhanced support at NAOs. They are: large-scale structure of universe, formation and evolution of galaxies, high-energy and cataclysmic processes in astrophysics, star formation and evolution, solar magnetic activity and heliogeospace environment, astrogeodynamics, dynamics of celestial bodies in the solar system and artificial bodies, space-astronomy technology, and new astronomical techniques and methods.

Abstract The Institute of High Energy Physics (IHEP), Chinese Academy of Sciences (CAS), is China's biggest laboratory for basic sciences. IHEP aims to understand the universe at the most fundamental level—from the smallest subatomic particles to the large-scale structure of the cosmos. As well as theoretical and experimental research into particle and astroparticle physics, IHEP has a broad range of research in related fields from accelerator technologies to nuclear analysis techniques. The Institute also provides beam facilities for researchers in other fields of sciences.

Abstract In this paper, we consider all P-wave $\Omega_{b}$ states represented by interpolating currents with a derivative and calculate the corresponding masses and pole residues with the method of QCD sum rule. Due to the large uncertainties in our calculation compared with the small difference in the masses of the excited $\Omega_{b}$ states observed by the LHCb collaboration, it is necessary to study other properties of the P-wave $\Omega_{b}$ states represented by the interpolating currents investigated in the present work in order to have a better understanding about the four excited $\Omega_{b}$ states observed by the LHCb collaboration.

Abstract China has invested heavily in nanotechnology in the past decades. It's one of the key areas of focus in the medium and long-term scientific programmes between 2006 and 2020. In 2012, the country also launched a Strategic Pioneering Programme on nanotechnology, which has a budget of one billion yuan (US$152 million) over five years and is led by the Chinese Academy of Sciences (CAS) in Beijing. As a result of this long-term investment, China is now a major player in nanotechnology, ranking first worldwide in terms of the number of scientific papers and patents. At the Sixth International Conference on Nanoscience and Technology—which was held in Beijing on 3–5 September, 2015—Chunli Bai, President of CAS and Editor-in-Chief of National Science Review (NSR), shared a platform with another five leading scientists, where they discussed recent progress of nanotechnology in China, the potential impact of nanoparticles on public health, as well as challenges and opportunities ahead.

Abstract In this paper, we pioneer a new machine-learning method to search for H ii regions in spectra from The Large Sky Area Multi-Object Fiber Spectroscopic Telescope (LAMOST). H ii regions are emission nebulae created when young and massive stars ionize nearby gas clouds with high-energy ultraviolet radiation. Having more H ii region samples will help us understand the formation and evolution of stars. Machine-learning methods are often applied to search for special celestial bodies such as H ii regions. LAMOST has conducted spectral surveys and provided a wealth of valuable spectra for the research of special and rare celestial bodies. To overcome the problem of sparse positive samples and diversification of negative samples, a novel method called the self-calibrated convolution network is introduced and implemented for spectral processing. A deep network classifier with a structure called a self-calibrated block provides a high precision rate, and the recall rate is improved by adding the strategy of positive-unlabeled bagging. Experimental results show that this method can achieve better performance than other current methods. Eighty-nine spectra are identified as Galactic H ii regions after cross-matching with the WISE Catalog of Galactic H ii Regions, confirming the effectiveness of the method proposed in this paper.

Abstract While China's almost flawless space endeavours—such as its space lab Tiangong-2, launched last year, and the 2012 mission that sent a rover to the surface of the Moon—have long impressed the world, space-science missions were not among its priorities until recently. The situation improved in 2011 when the Chinese Academy of Sciences won government support for a 10-year Strategic Pioneering Programme on Space Science—with a total budget of nearly 1 billion dollars. Since then, China has launched satellites to probe dark matter, detect black holes and conduct quantum experiments from space. This year will see the launch of an astronomy satellite and a highly anticipated mission to bring back rocks from the Moon. In a forum chaired by National Science Review's Executive Associate Editor Mu-ming Poo, space scientists discussed different types of Chinese space programmes, the science missions already launched or in development, the importance and challenges of international collaboration, and the uncertain future of the country's space-science development.

Abstract China boasts one of the largest scientific forces in the world, but most research institutes focus on a specialized subject of research—which many say are insufficient to meet the country's complex development needs. As part of the reform of scientific institutions and the implementation of innovation-driven development strategies, the Chinese government plans to build several comprehensive national laboratories that it hopes will further boost its scientific research prowess and to support large-scale projects. To rev up their construction and management, 12 of the world's top national-laboratory experts were invited to share their experiences and insights at the International Seminar on National Laboratory Management, which was held in Beijing on 2 February 2016. In a forum chaired by Tieniu Tan, Vice President of Chinese Academy of Sciences, a panel of four scientists discussed with a packed audience why multi-purpose national laboratories are important, how to manage them effectively, and what the main challenges are.

The report is based on the first results of the study "The History of the Evangelical Christians-Baptists in Ukraine", carried out in 1994-1996 by the joint efforts of the Department of Religious Studies at the Institute of Philosophy of the National Academy of Sciences of Ukraine and the Odessa Theological Seminary of Evangelical Christian Baptists. A large-scale description and research of archival sources on the history of evangelical movements in our country gave the first experience of fruitful cooperation between secular and church researchers.
