Abstract The study aimed at investigating the efficacy of written corrective feedback (CF) in improving Iranian EFL learners’ grammatical accuracy. It compared the effects of focused and unfocused written CF on the learners’ grammatical accuracy. 75 EFL students formed a one control and two experimental groups. The focused feedback group was provided with error correction in tenses. The unfocus...
In this paper, a Peak to Average Power Ratio (PAPR) reduction technique in Orthogonal Frequency Division Multiplexing (OFDM) systems is proposed. This technique uses error correction capability of channel coding to reduce the PAPR.The coded bits at the input of OFDM modulator are separated into two groups of the Most Significant Bits (MSB) and the LeastSignificant Bits (LSB). The bits are mappe...
purpose: to report a case who had undergone lasik in his right eye and prk in the fellow eye for correction of equivalent myopia but developed progressive post-operative keratectasia only in the right eye. patient and findings: a 30-year-old man had undergone lasik in right eye 3 years ago for correction of refractive error of -1.75 -1.50@48° and prk in left eye 2 years ago for correction of r...

Misclassification of disease status and risk factors is one of the main sources of error in studies. Wrong assignment of individuals into exposed and non-exposed groups may seriously distort the results in case-control studies. This study investigates the effect of misclassification error on odds ratio estimates and attempts to introduce a correction method. Data on 3332 men aged 30-69 years fr...
