The first data release(DR1) of the LAMOST regular survey

The Large sky Area Multi-Object Fiber Spectroscopic Telescope（LAMOST） general survey is a spectroscopic survey that will eventually cover approximately half of the celestial sphere and collect 10 million spectra of stars, galaxies and QSOs. Objects in both the pilot survey and the first year regular survey are included in the LAMOST DR1. The pilot survey started in October 2011 and ended in June 2012, and the data have been released to the public as the LAMOST Pilot Data Release in August 2012. The regular survey started in September 2012, and completed its first year of operation in June 2013. The LAMOST DR1 includes a total of 1202 plates containing 2 955 336 spectra, of which 1 790 879 spectra have observed signalto-noise ratio（SNR） ≥ 10. All data with SNR ≥ 2 are formally released as LAMOST DR1 under the LAMOST data policy. This data release contains a total of 2 204 696 spectra, of which 1 944 329 are stellar spectra, 12 082 are galaxy spectra and 5017 are quasars. The DR1 not only includes spectra, but also three stellar catalogs with measured parameters： late A,FGK-type stars with high quality spectra（1 061 918 entries）, A-type stars（100 073 entries）, and M-type stars（121 522 entries）. This paper introduces the survey design, the observational and instrumental limitations, data reduction and analysis, and some caveats. A description of the FITS structure of spectral files and parameter catalogs is also provided.

Quasars in the Galactic Anti-Center Area from LAMOST DR3

Abstract We present a sample of quasars discovered in an area near the Galactic Anti-Center covering 150°≤l≤ 210° and ｜b｜ ≤ 30°, based on LAMOST Data Release 3 （DR3）. This sample contains 151 spectroscopically confirmed quasars. Among them 80 are newly discovered with LAMOST. All these quasars are very bright, with i magnitudes peaking around 17.5 mag. All the new quasars were discovered serendipitously from objects that were originally targeted with LAMOST as stars having bluer colors, except for a few candidates targeted as variable, young stellar objects. This bright quasar sample at low Galactic latitudes will help fill the gap in the spatial distribution of known quasars near the Galactic disk that are used to construct an astrometric reference frame for the purpose of accurate proper motion measurements that can be applied to, for example, Gala. They are also excellent tracers to probe the kinematics and chemistry of the interstellar medium in the Milky Way disk and halo via absorption line spectroscopy.

A Catalog of Luminous Infrared Galaxies in the IRAS Survey and Second Data Release of SDSS

We selected a sample of luminous infrared galaxies by cross-identification of the Faint Source Catalogue （FSC） and Point Source Catalogue （PSC） of the IRAS Survey with the Second Data Release of the SDSS. The size of our sample is 1267 for FSC and 427 for PSC by using the 2a significance level cross-section. The ＂likelihood ratio＂ method is used to estimate the individual＇s reliability and for defining two more reliable subsamples （908 for FSC and 356 for PSC）. A catalog of infrared, optical and radio data is compiled and will be used in further work. Some statistical results show that luminous infrared galaxies are quite different from ultra-luminous infrared galaxies. The AGN fractions of galaxies at different infrared luminosities and the radio-infrared correlations are consistent with the previous studies.

Clinical application rules of different micro needle system therapy

Different micro needle system therapies have different advantages and characteristics.However,at present,the dominant diseases for which each therapy is appropriate are positioned relatively vaguely,and even the acupoint selections for the same disease are different.The clinical application of the dominant disease and application characteristics of each micro needle system therapy is a scientific problem that needs to be explored urgently.Based on the previous data mining study of the clinical application of auricular acupuncture,scalp acupuncture,abdominal acupuncture,eye acupuncture,wrist-ankle acupuncture,hand acupuncture,the second metacarpal bone lateral needling,facial acupuncture,mouth acupuncture and nose acupuncture,the diseases reported more in the clinical literature of each therapy were extracted to find out the same symptoms applicable to different micro needle systems.The clinical application and differences of different micro needle systems for the same disease were compared horizontally,and it demonstrated that the second metacarpal bone lateral needling,facial needle,mouth acupuncture and nose acupuncture were biased towards a partial corresponding therapeutic relationship between one part and the other part,and the eye acupuncture was biased to interfere with the whole by adjusting the function of the organs,and the auricular,scalp and abdominal needles had the both characteristics,and the wrist-malleolus acupuncture and hand acupuncture were often used in various disorders of the meridian-collateral level.The differences were researched and summarized to more accurately guide clinicians in the application of different micro needle system therapies.
