We measure the relationship between stellar mass and metallicity, mass--metallicity relation (MZR), for 1336 star-forming galaxies at $1.6\le z\le3.0$ (=2.2) using rest-frame far-ultraviolet spectra from zCOSMOS-deep survey. High signal-to-noise composite containing absorption features are fit with population synthesis model of a range metallicity. find metallicities, which mostly reflect ir...

We report the first measurement of exclusive cross sections $e^+e^-\to B\bar{B}$, B\bar{B}^*$, and B^*\bar{B}^*$ in energy range from 10.63 GeV to 11.02 GeV. The $B$ mesons are fully reconstructed a large number hadronic final states three channels identified using beam-constrained-mass variable. shapes show oscillatory behavior with several maxima minima. results obtained data collected by Bel...

Nanoparticles with unique catalytic, electronic, magnetic, optical and optoelectronic properties provide functional building blocks for organization into spatially well-defined assemblies, allowing for the possible extension of desirable properties of these nanoscale entities to the macroscopic level and the realization of complex devices. In the past decade, ‘bricksand-mortar’ assembly strateg...

Background: Over the last few decades, rates of active transport (AST) among school age children have decreased as rates of child obesity have increased. Thus, it has been proposed that increasing AST in this population would help stem the tide of child obesity and improve child health. The evidence for the capacity of AST to reduce child obesity, however, is mixed. Purpose: To examine the asso...

in this paper we proved that every g-riesz basis for hilbert space $h$ with respect to $k$ by adding a condition is a riesz basis for hilbert $b(k)$-module $b(h,k)$. this is an extension of [a. askarizadeh,m. a. dehghan, {em g-frames as special frames}, turk. j. math., 35, (2011) 1-11]. also, we derived similar results for g-orthonormal and orthogonal bases. some relationships between dual fram...
