Kepler satellite photometry and phase-resolved spectroscopy of the ultracompact AM CVn type binary SDSS J190817.07+394036.4 are presented. The average spectra reveal a variety of weak metal lines of different species, including silicon, sulphur and magnesium as well as many lines of nitrogen, beside the strong absorption lines of neutral helium. The phasefolded spectra and the Doppler tomograms...

Mongolian people often consume meat more than vegetable in diet due to traditional nomadic culture. Nowadays, the people’s has been changing who vegetables with associated urbanization (half of population live urban areas, mostly capital city). Even though consumption increased recently, market is still a high reliance on imports and threatening national food security. Since 2016, government es...

We propose that KIC 1573174 is a quadruple-mode $\delta$ Scuti star with pulsation amplitudes between those of the HADS (high-amplitude Delta star) group and average low-amplitude pulsators. The radial modes detected in this provide unique opportunity to exploit asteroseismic techniques up their limits. Detailed frequency analysis given for light curve from Kepler mission. variation dominated b...

This paper exploits the panel dimension of the Vietnam Living Standards Survey (VLSS) in order to analyze the main changes occurring in agriculture in Vietnam over the period 19931998. This period was marked by a continuation of the reforms that began in 1988 with the implementation of Resolution 10, Vietnam’s own version of the Chinese Househo ld Responsibility System. We focus on the impact o...

The human transcriptome comprises a myriad of non protein-coding RNA species, including long noncoding RNAs (lncRNAs), which have a remarkable role in transcriptional and epigenetic regulation. We hypothesized that variants in lncRNAs influence the susceptibility to nonalcoholic fatty liver disease (NAFLD). Using next generation sequencing, we performed a survey of genetic variation associated ...
