<p><strong>Abstract.</strong> To investigate mass transport and energy dissipation in space environments for solar system planet, a balloon-borne planetary atmospheric spectral telescope (PAST) is designed with 0.8-m aperture in spectral range from 280&amp;thinsp;nm to 680&amp;thinsp;nm will be floated at 35&amp;ndash;40&amp;thinsp;km altitude to observe and investigate the global space environment of Mercury, Venus, Mars, and Jupiter. The telescope is designed by Changchun Institute of Optics, Fine Mechanics and Physics, Chinese Academy of Sciences (CIOMP, CAS), and supported by the Strategic Priority Research Program of Chinese Academy of Sciences, that is the Scientific Experimental system in Near-SpacE (SENSE). The telescope is mainly supported by a Ritchey-Chrétien optical system which can achieve 0.5" angular resolution observation, and the optical system has the function of focusing and stabilizing. The telescope is combined with a two-dimension rotate platform to achieve planetary atmospheric imaging in long exposure time. This paper mainly introduces the PAST scheme briefly.</p>

A photometric solar seismograph, as part of an international network, was installed at Yunnan Observatory, the Chinese Academy of Sciences, and put into operation in the spring of 1991. This instrument is used to detect solar oscillations by measuring the continuum radiation intensity on the solar disk with a spatial resolution of 50 arcsec, in heliocentric coordinates, for research on p-modes and g-modes when l < 50, where l is the angular degree of the eigenfunction. The solar oscillations can be observed simultaneously at two wavelengths of the detector with a sensitivity of 10 of the average intensity. This paper reports on the optical system of the instrument. Also introduced in this paper is the compensation system for the noise signals produced by the changes in the transparency of the Earth's atmosphere. This is based on solar photometry at wavelengths of 0.55 mm and 1.6 mm.

Abstract. Solar-terrestrial prediction services in China began in 1969 at the Beijing Astronomical Observatory (BAO), Chinese Academy of Sciences (CAS). In 1990, BAO joined the International URSIgram and World Days Service (IUWDS) and started solar-terrestrial data and prediction interchanges with other members of IUWDS. The short-term solar activity prediction service with standard URSIgram codes began in January 1991 at BAO, and forecasts have been issued routinely every weekday from then on. The Regional Warning Center Beijing (RWC-Beijing) of IUWDS was officially approved in China in 1991 and was formally established in February 1992. In 1996, the IUWDS was changed to the current name, the International Space Environment Service (ISES). In 2000, the RWC-Beijing was renamed RWC-China according to ISES requirements. In 2001, the National Astronomical Observatories, CAS (NAOC) was established. All the solar-terrestrial data and prediction services of BAO were taken up by NAOC. The headquarters of RWC-China is located on the campus of NAOC.

The genus Pholcus Walckenaer, 1805 is reported from Pakistan for the first time. Two new species of the Pholcus nenjukovi species-group are described: Pholcus hamuchal Yao & Li sp. nov. (Gilgit Baltistan, male and female) and Pholcus kalam Yao & Li sp. nov. (Khyber Pakhtunkhwa, male and female). Type material is deposited in the Institute of Zoology, Chinese Academy of Sciences (IZCAS) in Beijing, China.

This paper describes recent research on the design, implement, and testing of a new small-scaled rotorcraft Unmanned Aerial Vehicle (RUAV) system—ServoHeli-40. A turbine-powered UAV weighted less than 15 kg was designed, and its major components were tested at the Shenyang Institute of Automation, Chinese Academy of Sciences in Shenyang, China. The aircraft was designed to reach a top speed of more than 20 mps, flying a distance of more than 10 kilometers, and it is going to be used as a test-bed for experimentally evaluating advanced control methodologies dedicated on improving the maneuverability, reliability, as well as autonomy of RUAV. Sensors and controller are all onboard. The full system has been tested successfully in the autonomous mode using the multichannel active modeling controller. The results show that in a real windy environment the rotorcraft UAV can follow the trajectory which was assigned by the ground control station exactly, and the new control method is obviously more effective than the one in the past year's research.

The paper presents a Scientometrics mapping of papers published inJournal of Computer Science and Technology, during 2012 to 2016 as reflected in Web of Science database. It attempts to analyze the growth and development of publications output of Journal of Computer Science and Technologyas reflected. Data for a total of 485 have been downloaded and analysed according to objectives. The study reveals thatThe year wise growth rate revel that highest no. papers published in 2015, No. of Papers: 106 (21.86%) Authorship pattern data reveals that most of the authors like to publish papers in collaborations and most preferred authorship pattern was four author i.e. no. publications for four authors were 125 (25.77 %). The Degree of Collaboration (DC) revel that DC is found highest in 0.95 Co-Authored Publication. The highly prolific authors and their publications revel that Zhang L, published highest numbers of papers (11 nos.), the geographical distribution contributions (International) is revel that Peoples R China is in the top with no. of publications is 371 (76.50%), it is found from institution-wise distribution of papers that highest contributed institutions was Chinese Academy of Sciences with 93 Publications (19.18%) is placed at 1st rank and the average of citations per year (2012-2016) were 205.
