The properties of a Higgs boson candidate are measured in the H → ZZ → 4l decay channel, with l 1⁄4 e, μ, using data from pp collisions corresponding to an integrated luminosity of 5.1 fb−1 at the centerof-mass energy of ffiffi s p 1⁄4 7 TeV and 19.7 fb−1 at ffiffi s p 1⁄4 8 TeV, recorded with the CMS detector at the LHC. The new boson is observed as a narrow resonance with a local significance...

The properties of a Higgs boson candidate are measured in the H → ZZ → 4` decay channel, with ` = e, μ, using data from pp collisions corresponding to an integrated luminosity of 5.1 fb−1 at the center-of-mass energy of √ s = 7 TeV and 19.7 fb−1 at √ s = 8 TeV, recorded with the CMS detector at the LHC. The new boson is observed as a narrow resonance with a local significance of 6.8 standard de...

The study of the spin-parity and tensor structure of the interactions of the recently discovered Higgs boson is performed using the H → ZZ; Zγ ; γ γ → 4l, H → WW → lνlν, and H → γγ decay modes. The full data set recorded by the CMS experiment during the LHC run 1 is used, corresponding to an integrated luminosity of up to 5.1 fb−1 at a center-of-mass energy of 7 TeVand up to 19.7 fb−1 at 8 TeV....

[1] Trends and interannual variability of the surface winds (SW), sea surface height (SSH), and sea surface temperature (SST) of the South China Sea (SCS) in 1993–2003 are analyzed using monthly products from satellite observations. Time series are smoothed with a 12-month running mean filter. The east and north components of the SW, SSH, and SST have linear trends of 0.53 ± 0.35 ms 1 decade , ...

In this research study the daily and annually trends of precipitation in the central Kavir basin of Iran during 1951- 2007. The pixel data of daily precipitation from APHRODITE’s data base with a spatial resolution of 0.25˚ have been used. The Mann-Kendall (MK) nonparametric test has been used for determining the precipitation trend in this area. The trends have been tested in 3 levels 90...

‎Small area estimates have received much attention from both private and public sectors due to the growing demand for effective planning of health services‎, ‎apportioning of government funds and policy and decision making‎. ‎Surveys are generally designed to give representative estimates at national or district level‎, ‎but estimates of variables of interest are oft...

In the present research, the difference between the quality of life of fourth-grade schoolboys in ordinary schools and those in schools of life in the city of Tehran have been studied. A descriptive, causal-comparative approach was used. The statistical population consisted of all fourth-grade elementary school students in ordinary schools and schools of life in the city of Tehran. The statisti...

It is generally accepted that performance-based design has to be reliability-based. Seismic performance evaluation is based on nonlinear dynamics and reliability theory taking into account uncertainties during analysis. Considering the economic importance of jacket type offshore platforms, the present research aims to assess the seismic performance of offshore steel platforms. In this study, th...
