Abstract The fourth generation of the Sloan Digital Sky Survey (SDSS-IV) began observations in 2014 July. It pursues three core programs: Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2), Mapping Nearby Galaxies at APO (MaNGA), and Extended Baryon Oscillation Spectroscopic (eBOSS). As well as its program, eBOSS contains two major subprograms: Time Domain (TDSS) SPectroscopic IDentification ERosita Sources (SPIDERS). This paper describes first data release from SDSS-IV,...

Rabbit meat could play an important role in health, the rural economy, and sustainable development. has excellent nutritional features, such as high protein content, low-fat a percentage of unsaturated fatty acids, low cholesterol sodium levels. In addition, rabbit production contributes to maintaining economic activities marginal areas. However, consumption is still limited due several factors higher cost commercial food that slowing down rabbits’ breeding. Socio-demographic...
We measure equivalent widths (EW) - focussing on two unique features (NaI and TiO2) of low-mass stars (<0.3M\odot) for luminous red galaxy spectra from the Sloan Digital Sky Survey (SDSS) X-Shooter Lens (XLENS) in order to study end initial mass function (IMF). compare these EWs those derived simple stellar population models computed with different IMFs, ages, [{\alpha}/Fe], elemental abundances. find that are able simultaneously reproduce observed NaD {\lambda}5895 Na I {\lambda}8190...

Inflammatory bowel disease (IBD) is a group of recurrent chronic inflammatory diseases, including Crohn’s (CD) and ulcerative colitis (UC). Although IBD has been extensively studied for decades, its cause pathogenesis remain unclear. Existing research suggests that may be the result an interaction between genetic factors, environmental factors gut microbiome. closely related to non-coding RNAs (ncRNAs). NcRNAs are composed microRNA(miRNA), long RNA(lnc RNA) circular RNA(circ RNA). Compared...

This paper probes into positioning in colleges, deeply analyzes current situation provides countermeasures teachers.
Royal Jelly (RJ) is a natural substance produced by honeybees, serving not only as nutrition for bee brood and queens but also functional food due to its health-promoting properties. Despite well-known broad-spectrum antibacterial activity, the precise molecular mechanism underlying action has remained elusive. In this study, we investigated impact of RJ on bacteria model MG1655 at half-maximal inhibitory concentration, employing LC-MS/MS analyze proteomic changes. The differentially...

Aims. The path towards robust near-infrared extensions of stellar population models involves the confrontation between empirical and synthetic spectral libraries across wavelength ranges photospheric emission. Indeed, theory emission enters all synthesis models, even when this is only implicit in association fundamental parameters with library stars.
