The softening of the radial breathing mode (RBM) of metallic single walled carbon nanotubes (m-SWNTs) due to electron-phonon coupling has been studied by observing the Fermi level [see text] dependence of the RBM Raman peak. In situ Raman spectra were obtained from several individual m-SWNTs while varying [see text] electrochemically. The RBM frequency of an intrinsic m-SWNT is shown to be down...

In this paper, the radial breathing mode (RBM) frequencies of multi-walled carbon nanotubes (MWCNTs) are  obtained based on the multiple-elastic thin shell model. For this purpose, MWCNT is considered as a multiple concentric elastic thin cylindrical shells, which are coupled through van der Waals (vdW) forces between two adjacent tubes. Lennard-Jones potential is used to calculate the vdW ...

conclusions physicians involved in care of methadone patients should recommend dietary and lifestyle changes to improve their overall health. results within one year from admission to treatment, a statistically significant (t-tests, p < 0.05) increase was noted in their body mass index (bmi), % of body fat, average body mass, and average basal metabolic rate, and relative decrease in their % of...

background: the aim of this study was to assess the predictive capacity of body composition estimated by bioelectrical impedance analysis (bia) to identify abnormal blood pressure in physical education and sport teaching students in the city of ankara. methods: data for this cross-sectional study were obtained in the city of ankara in 2014. a total of 133 students aged 20-35 yr participated in ...

background one of the most pressing threats for children’s health status is overweight and obesity. previous literature indicates that increasing relative body mass index (rbmi) is accompanied by physical inactivity. objectives the aim of this study was to determine the prevalence of daily physical activity and obesity among students grade 5th and 6th. patients and methods this was a cross-sect...

Restricted Boltzmann Machines (RBMs) have shown success in different stages of speaker recognition systems. In this paper, we propose a novel framework to produce a vector-based representation for each speaker, which will be referred to as RBMvector. This new approach maps the speaker spectral features to a single fixed-dimensional vector carrying speaker-specific information. In this work, a g...

The research objective is assessment of structural genomic damages in plutonium workers. The study group included workers of the Mayak Production Association subjected to chronic occupational internal exposure to incorporated Pu and/or external γ-rays. A lymphocyte culture of peripheral blood was chosen as an object of study. The yield of intrachromosomal exchange aberrations of chromosomal typ...

abstract background: a wealth of study shows that increasing rbmi accompanies with physical inactivity, consequently. the aims of this study were determining the distribution of daily physical activity amount by gender in obese and overweight students methods: this is a cross-sectional descriptive study carried out to determine the distribution of daily physical activity level by genders and re...

Restricted Boltzmann Machines (RBM) are simple statistical models defined on a bipartite graph which have been successfully used in studying more complicated many-body systems, both classical and quantum. In this work, we exploit the representation power of RBMs to provide an exact decomposition contact interactions into one-body operators coupled discrete auxiliary fields. This construction ge...
