the most important and practical phase of analyzing the linguistic errors of second language learners is to find the solutions to decrease these errors. to that end, the present study examined translation strategy to decrease the number of grammatical and lexical errors of chinese language learners learning persian. twelve chinese language learners were asked to write a text in two stages. firs...

introduction: dictation as an important academic ability involves divers cortical processes so that any problem in one of them may lead to a dictation error. identifying current dictation errors helps specialists to understand its causes more comprehensively and to use the most effective interventional approaches. the aim of this study was to compare the most common dictation errors between pri...

We consider the combined effect of readout errors and coherent errors, i.e., deterministic phase rotations, on surface code. use a recently developed numerical approach, via mapping physical qubits to Majorana fermions. show how this approach in presence treated phenomenological level: perfect projective measurements with potentially incorrectly recorded outcomes, multiple repeated measurement ...

     Medication errors (MEs) are the most common error in ICUs. In fact, 78% of all serious errors in ICUs are due to MEs. Therefore, detecting MEs has vital significance. The goal of this study was to investigate the frequency, type and consequences of different types of errors including prescribing, transcribing and administration errors in an ICU of a large teaching hospital. Disguised direc...

purpose: to compare post-operative pain with cooling photorefractive keratectomy (prk) versus conventional prk. methods: a prospective clinical trial was performed on 94 eyes from 47 patients scheduled for prk. patients were randomly assigned to either cooling or conventional prk. pain was evaluated 6, 12, 24 and 48 hours post-operation using a visual analogue scale (vas). corneal haze, conjunc...
