BACKGROUND  Right atrial pressure (RAP) is commonly estimated using inferior vena cava (IVC) diameter and its respirophasic variations. Although a guideline has been provided for estimation of RAP due to variation in IVC dimensions based on studies in Western subjects, echocardiographic values in Asian subjects are unknown. METHODS AND RESULTS  We studied 369 patients who underwent IVC ultras...

We study the non-parametric estimation of an unknown survival function S with support on R+ based a sample multiplicative measurement errors. The proposed fully-data driven procedure is Mellin transform and regularisation inverse by spectral cut-off. upcoming bias-variance trade-off dealt data-driven choice cut-off parameter. In order to discuss bias term, we consider Mellin-Sobolev spaces whic...

background: brucellosis is a world-wide disease, which has a diverse clinical manifestation, and its diagnosis has to be proven by laboratory data. serum agglutination test (sat) is the most-widely used test for diagnosing brucellosis. the enzyme linked immunosorbent assay (elisa) can also determine specific antibody classes against brucella. it is a sensitive, simple and rapid test, which coul...

We propose a new method of spin squeezing of atomic spin, based on the interactions between atoms and off-resonant light which are known as paramagnetic Faraday rotation and the fictitious magnetic field of light. Since the projection process, squeezed light, or special interactions among the atoms are not required in this method, it can be widely applied to many systems. The attainable range o...

Defocusing effects in modulation transfer function (MTF) measurement of charge coupled device (CCD) cameras is the main focus of current paper. We introduce measuring Point-spread function (PSF) in order to calculate the MTF and further more we will study the shape of MTF and its cut-off frequency by adjusting the lens focusing in different locations. A collimated white light LED by broadband s...

In the off-diagonal basis, we discuss the contributions of the non-universal gauge boson Z ′ predicted by the topcolor-assisted technicolor (TC2) model to the spin configurations and the spin correlation observable of the top quark pair production via the process e−e+ → tt̄. Our numerical results show that the production cross sections for the like-spin states, which vanish in the standard model...

background: evaluation of anti-mullerian hormone (amh) cut-off levels in assisted reproductive technology (art) as predictive factor for individualization of stimulation protocols and to avoid ovarian hyperstimulation syndrome (ohss). materials and methods: in a retrospective study, 177 infertile patients were assessed for amh in serum and follicular fluid (ff) on the day of follicular puncture...

Background: Hypoglycemia is one of the most common neonatal disorders, associated with severe complications. There has been a great deal of controversy regarding the definition and screening of hypoglycemia. Therefore, in this study, we aimed to determine a cut-off value for blood glucose level in glucometer readings. Methods: This cross-sectional study was conducted on 238 newborns at risk of ...

Background: There are few psychometric studies addressing sensitivity and specificity of the Persian version of the Edinburgh Postnatal Depression Scale (EPDS). Therefore, there is a need for future studies to identify the best cut-off point for EPDS score. The present study is aimed at assessing the validity of the EPDS among Iranian mothers. Materia...
