Software defect prediction aims to determine whether a software module is defect-prone by constructing models. The performance of such models susceptible the high dimensionality datasets that may include irrelevant and redundant features. Feature selection applied alleviate this issue. Because many feature methods have been proposed, there an imperative need analyze compare these methods. Prior empirical studies potential controversies limitations, as contradictory results, usage private...
We present extensive optical observations of a Type IIn supernova (SN) 2010jl for the first 1.5 years after discovery. The UBVRI light curves demonstrated an interesting two-stage evolution during nebular phase, which almost flatten out about 90 days from maximum. SN has one highest intrinsic H_alpha luminosity ever recorded IIn, especially at late suggesting strong interaction ejecta with dense circumstellar material (CSM) ejected by progenitor. This is also indicated remarkably Balmer...
We present the rest-frame near-ultraviolet (NUV) spectroscopy of star-forming galaxies (SFGs) at 0.6<z<1.2 from Extended Baryon Oscillation Spectroscopic Survey (eBOSS) in SDSS-IV. One eBOSS programs is to obtain 2 arcsec (about 15 kpc) fiber spectra about 200,000 emission-line (ELGs) redshift z>0.6. use data pilot observations this program, including 8620 SFGs 0.6<z<1.2. The median composite these 2200 Ang < \lambda 4000 feature asymmetric, preferentially blueshifted non-resonant emission,...
We present 127 new transit light curves for 39 hot Jupiter systems, obtained over the span of five years by two ground-based telescopes. A homogeneous analysis these newly collected together with archived spectroscopic, photometric, and Doppler velocimetric data using EXOFASTv2 leads to a significant improvement in physical orbital parameters each system. All our stellar radii are constrained accuracies better than 3\%. The planetary 37 targets determined $5\%$. Compared results, literature...
Android apps have played important roles in daily life and work. To meet the new requirements from users, encounter frequent updates, which involves a large quantity of code commits. Previous studies proposed to apply Just-in-Time (JIT) defect prediction for timely identify whether commits can introduce defects into apps, aiming assure their quality. In general, high-quality features are benefits improving classification performance. addition, number defective commit instances is much fewer...
Photometric redshift (photo-z) is a fundamental parameter for multi-wavelength photometric surveys, while galaxy clusters are important cosmological probers and ideal objects exploring the dense environmental impact on evolution. We extend our previous work estimating photo-z detecting to latest data releases of Dark Energy Spectroscopic Instrument (DESI) imaging Survey (DES), Hyper Suprime-Cam Subaru Strategic Program (HSC-SSP) surveys make corresponding catalogs publicly available more...
Abstract Propyl gallate (PG) is one of the most widely used antioxidants in food products, cosmetics and pharmaceutical industries. Increased research has suggested that exposure to PG influences reproductive health humans animals. However, until now, it not yet been confirmed whether would impact oocyte quality. In this study, hazardous effects on meiotic maturation were investigated mice. The findings showed compromises meiosis by inducing mitochondrial stress which activates apoptosis...
More than eight million smart contracts have been deployed into Ethereum, which is the most popular blockchain that supports contract. However, less 1% of are open-source, and it difficult for users to understand functionality internal mechanism those closed-source contracts. Although a few decompilers recently proposed, still not easy grasp semantic information contract, mention potential misleading due decompilation errors. In this paper, we propose first system named Stan generate...
This paper studies the color behavior of BL Lac object OJ 287 during an optical outburst. Upon revisiting data from 94 monitoring project, and analysis obtained with 60/90 cm Schmidt Telescope NAOC, we found a bluer-when-brighter chromatism in this object. The amplitude variation tends to decrease frequency. These results are consistent shock-in-jet model. We ran some simulations confirmed that both difference time delay between variations at different wavelengths can result phenomenon. Our...
The weather at the Xinglong Observing Station, where Guo Shou Jing Telescope (GSJT) is located, strongly affected by monsoon climate in northeast China. LAMOST survey strategy constrained these patterns. We present statistics on observing hours from 2004 to 2007, and sky brightness, seeing, transparency 1995 2011 site. investigate effects of site conditions plan. Operable each month show a strong correlation with season: average there are eight operable per night available December, but only...
We report the first results of star counts carried out with National Astronomical Observatories (NAOC) cm Schmidt Telescope in 15 intermediate-band filters from 3000 to 10 000 Å BATC survey. analyze a sample over 1400 main sequence stars (), which lie field central coordinates and (J2000) (Galactic coordinates: ). The view is 0.95 deg2, spatial scale was . Since at high galactic latitudes are not strongly related radial distribution, they well suited study vertical distribution Galaxy. In...

Using the stellar atmospheric parameters such as effective temperature and metallicity derived from SDSS spectra for 2200 main sequence (MS) stars which were also observed by Beijing - Arizona Taiwan Connecticut (BATC) photometric system, we develop polynomial calibration method to evaluate BATC multi-color data. This has been applied about 160 000 MS 67 fields. Those have colors magnitudes in ranges 0.1 < d h 1.4 14.0 21.0. We find that there is a peak of distribution at [Fe/H] ~ -1.5...
