in this study, the ability of generalized additive model (gam) for mapping potential distribution of ferula ovina boiss, and the description of species response curves to environmental variables were examined in fereidonshar region with area of 1000 square kilometers located in west of isfahan province. the presence and absence data of the species were collected from 278 sites (including 138 pr...

results roc-derived spo2 threshold of ≤ 94% can predict hypoxemia (pao2 < 60 mmhg) with a sensitivity of 100% and a specificity of 95%. furthermore, there are associations between the roc-derived spo2 threshold of ≤ 97% and detection of hypoxemia (pao2 < 70 mmhg) with a sensitivity of 100% and a specificity of 46%. the accuracy of pulse oximetry was not affected by the severity of liver disease...

Resonance trapping appears in open many-particle quantum systems at high level density when the coupling to the continuum of decay channels reaches a critical strength. Here a reorganization of the system takes place and a separation of different time scales appears. We investigate it under the influence of additional weakly coupled channels as well as by taking into account the real part of th...

The formation–distribution of condensed water in diffusion medium of proton exchange membrane fuel cells, and its tendency to reduce the local effective mass diffusivity and to influence cell performance, are studied. First the local effective mass diffusivity of a fibrous diffusion medium is determined as a function of the local porosity and local water saturation, using the network model for ...

We find supersaturation for the intrinsic gluon distribution of nuclei, i.e. the low x unintegrated nuclear gluon distribution peaks at intermediate transverse momenta kt = Qs and vanishes at zero kt. Taking into account the intrinsic transverse momenta of the gluons and the saturation scale ps of the produced gluons, we calculate the minijet cross section arising from gluon gluon scattering fo...

We investigate the recently proposed nonlinear equation for the unintegrated gluon distribution function which includes the subleading effects at small x. We obtained numerically the solution to this equation in (x, k) space, and also the integrated gluon density. The subleading effects affect strongly the normalization and the x and k dependence of the gluon distribution. We show that the satu...

this paper is a report on the synthesis of the fe3o4@ag core-shell with high saturation magnetization of magnetite nanoparticles as the core, by using polyol route and silver shell by chemical reduction. x-ray diffraction (xrd) and fourier transform infrared spectroscopy analyses confirmed that the particles so produced were monophase. the magnetic properties of the product were investigated by...
