Monthly Notices of the Royal Astronomical Society, 2020 ABSTRACTIn this work, we report a list of 91 strong Th ii spectral lines in the visible wavelength region that could be used as cosmochronometers in future investigations to determine stellar ages from thorium radioactive decay. This list was established on the basis of a pseudo-relativistic Hartree–Fock model including core-polarization corrections ...

Frontiers in Astronomy and Space Sciences, 2022 We performed a comprehensive investigation of methyl cyanoacetate (MCA) using high-resolution Fourier transform rotational spectroscopy. Two low energy conformers of MCA were observed in the vibrational ground state, in selected frequency regions from 2 ...

ON THE GF-VALUES FOR SOME DIATOMIC MOLECULAR SPECTRA
Odessa Astronomical Publications, 2017 In view of rich structure of the energy levels and the variety of transition types which are observable, molecules are the useful tool for investigation of physical parameters of stellar atmospheres, interstellar and circumstellar matter.

Molecules in Cool Stars: The A2Π − X2Σ+ and the B2Σ+ − X2Σ+ Band Systems of CaCl
The Astrophysical JournalCool red giant stars exhibit absorption bands of calcium monochloride (CaCl) in the optical region. In this work, the bands of CaCl corresponding to the A ^2 Π − X ^2 Σ ^+ transition with ${v}^{{\prime} }\leqslant $ 4 and v ″ ≤ 4, and B ^2 Σ ^+ − X ^2 Σ ^

Strategy for high-accuracy-and-precision retrieval of atmospheric methane from the mid-infrared FTIR network [PDF]
Atmospheric Measurement Techniques, 2011 We present a strategy (MIR-GBM v1.0) for the retrieval of column-averaged dry-air mole fractions of methane (XCH<sub>4</sub>) with a precision <0.3% (1-σ diurnal variation, 7-min integration) and a seasonal bias <0.14% from mid-infrared

Molecular Oncology, EarlyView.This study explores salivary RNA for breast cancer (BC) diagnosis, prognosis, and follow‐up. High‐throughput RNA sequencing identified distinct salivary RNA signatures, including novel transcripts, that differentiate BC from healthy controls, characterize histological and molecular subtypes, and indicate lymph node involvement.

The A2Π–X2Σ+ Band System of ScO for M-type Star Spectral Analysis
The Astrophysical JournalM-type stars are the most abundant stars in our Galaxy. Their visible spectra are characterized by strong TiO and VO absorption bands with occasional ScO bands near 6000–6100 Å.

Molecular Oncology, EarlyView.A‐to‐I editing of miRNAs, particularly miR‐200b‐3p, contributes to HGSOC progression by enhancing cancer cell proliferation, migration and 3D growth. The edited form is linked to poorer patient survival and the identification of novel molecular targets.
