The Paschen decrement as a density indicator in MWC349
We present new observations of the Paschen series hydrogen recombination lines in the circumstellar shell of MWC349. We find the Paschen decrement to be characteristic of a very high density plasma, ne ∼ 108 cm−3, indicating the origin of the higher quantum number Paschen lines in the dense corona of the circumstellar disk. The strength of the masing hydrogen recombination α-lines detected prev...
متن کاملVowel space density as an indicator of speech performance.
The purpose of this study was to develop a method for visualizing and assessing the characteristics of vowel production by measuring the local density of normalized F1 and F2 formant frequencies. The result is a three-dimensional plot called the vowel space density (VSD) and indicates the regions in the vowel space most heavily used by a talker during speech production. The area of a convex hul...
متن کاملHigh -density lipoprotein cholesterol as a predictor for diabetes mellitus
Background: Diabetes is a prevalent chronic disease around the world. To evaluate risk of diabetes comprehensively, we developed a score model for the risk prediction with HDL-C as a protective factor. Methods: We extracted physical examination data of 2728 individuals. The data contain 18 demographic and clinical variables. To identify the statistical significant feature variables, the backwa...
متن کاملThe dipole moment of the spin density as a local indicator for phase transitions
The intra-atomic magnetic dipole moment - frequently called ⟨Tz⟩ term - plays an important role in the determination of spin magnetic moments by x-ray absorption spectroscopy for systems with nonspherical spin density distributions. In this work, we present the dipole moment as a sensitive monitor to changes in the electronic structure in the vicinity of a phase transiton. In particular, we stu...
