one of the problems of learners that often impairs learning a second language is syntactic errors. therefore, the present study investigates the syntactic errors of arab speakers learning persian. this research is based on contrastive analysis approach. in this article, interlingual syntactic errors committed in learner’s writings are studied, using field method and through a content analysis o...

For technologies that are commonly used in ordinary laboratories such as fluorescence-polarization detection with template-directed, dye-terminator incorporation (FP-TDI), SNP genotype scoring is usually done manually. Here we study rates of errors and missing genotypes obtained with this procedure. We also introduce three statistical genotype scoring methods to examine whether they form a viab...

Three methods of synthesizing correlations for meta-analytic structural equation modeling (SEM) under different degrees and mechanisms of missingness were compared for the estimation of correlation and SEM parameters and goodness-of-fit indices by using Monte Carlo simulation techniques. A revised generalized least squares (GLS) method for synthesizing correlations, weighted-covariance GLS (W-C...

The common causes of 18p deletion syndrome are spontaneous errors in the chromosomal structure in the early stages of human embryonic development. In this study, a 29-year-old girl was introduced with the features of deletion of chromosome 18. In addition, GTG banding karyotype revealed that this case had a deletion involving the short arm of chromosome 18. In comparison with the usual phenotyp...

This paper considers error-correction for information in array design, i.e., two-dimensional design such as QR-codes. The error model is multi deletion/substitution/erasure errors. Code construction the errors and an application of code are provided. decoding technique uses error-locator deletion codes.

echocardiography is considered the primary diagnostic tool for congenital heart diseases. the pediatric echocardiography diagnostic errors, consisting of false positive or discrepant diagnoses, picked up within a 2.5-year period in our pediatric echocardiography laboratory are presented herein. in this case report, the factors contributing to the diagnostic errors are categorized as cognitive s...

OBJECTIVE To describe and analyse the role of the pharmacy department in detecting errors in the prescription of cytostatic drugs. METHOD A retrospective study was carried out over a two year period (2003-2004), which reviewed the errors detected by pharmacists in chemotherapy prescriptions. Medication errors were classified according to the system published by Otero et al. in the paper OErro...

In this paper we present the rst parallel minimumdistance error{correcting parser for context{free languages. The error correction is performed considering three kinds of syntax errors: the mutation of a symbol in another incorrect symbol, the insertion of an extraneous symbol and the deletion of a symbol. Our algorithm has the same parallel complexity of other well{known non{correcting context...
