In the nonparametric deconvolution problem, in order to estimate consistently a density or distribution from a sample of data contaminated by additive random noise, it is often assumed that the noise distribution is completely known or that an additional sample of replicated or validation data is available. Methods also have been suggested for estimating the scale of the error distribution, but...
We review optical observations and theoretical models of the non-magnetic nova-like variables (UX UMa, VY Scl and SW Sex stars). A brief discussion of the classiication scheme is followed by a statistical overview of the observed properties. The most important features of each of the sub-classes are then reviewed, concluding with a summary of the theoretical models invoked to understand these s...
one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
the purpose of this study was to examine the english language needs of medical students at tehran university of medical sciences . analysis of the needs took place for three groups: 320 undergraduate students, 30 postgraduate students and 20 university instructors. a triangulation approach to collect data was used in which a combination of the quantitative (using the questionnaires) and qualita...
OBJECTIVE To investigate the correlation between gamma-glutamyltransferase (GGT) and remnant-like particle cholesterol (RLP-C) in dyslipidemic patients. SUBJECTS AND METHODS General cardiometabolic variables, plus serum GGT and RLP-C levels, were measured in 118 dyslipidemic patients (59 males, mean age 58 ± 13 years). Correlation analyses of GGT with other variables, including RLP-C, were pe...
Background and Objectives: Regular blood transfusions in patients with hereditary hemolytic anemia, especially thalassemia, increase the survival of most patients but also may result in infection with viruses like hepatitis. In order to identify these diseases and other complications in people with thalassemia, this study aimed to investigate epidemiological and clinical findings in patients wi...
We offer an approximation to central confidence intervals for directly standardized rates, where we assume that the rates are distributed as a weighted sum of independent Poisson random variables. Like a recent method proposed by Dobson, Kuulasmaa, Eberle and Scherer, our method gives exact intervals whenever the standard population is proportional to the study population. In cases where the tw...
