the aim of the present study was to investigate the frequency and the type of discourse markers used in the argumentative and expository writings of iranian efl learners and the differences between these text features in the two essay genres. the study also aimed at examining the influence of the use of discourse markers on the participants’ writing quality. to this end the discourse markers us...
Although not mentioned by Dr. Psaty in his commentary (1), concerns have been raised over the heart failure results in ALLHAT (2). Asymptomatic left ventricular (LV) systolic dysfunction is common in older patients, particularly men and patients with cardiovascular risk factors (3, 4). ALLHAT participants were high-risk patients, and many may have had asymptomatic LV dysfunction that could have...
Intervention Participants were allocated to 1 of three 30 minute exposure conditions: GTR (n=13); SBU (n=17); and exposure alone (n=12). Exposure consisted of 2 BATs: a claustrophobia chamber (BAT 1) and a tall filing cabinet (BAT 2). All participants were told that claustrophobia is driven by concerns about lack of fresh air or being trapped. The GTR group was told of the efficacy of eliminati...
P a t i e n t s 1219 patients with an out-of-hospital cardiac arrest who presented with ventricular fibrillation, pulseless electrical activity, or asystole requiring cardiopulmonary resuscitation (CPR) with vasopressor therapy. Exclusion criteria were successful defibrillation without a vasopressor, terminal illness, no intravenous access, hemorrhagic shock, cardiac arrest after trauma, pregna...
Wavelet, a powerful tool for signal processing, can be used to approximate the target function. For enhancing the sparse property of wavelet approximation, a new algorithm was proposed by using wavelet kernel Support Vector Machines (SVM), which can converge to minimum error with better sparsity. Here, wavelet functions would be firstly used to construct the admitted kernel for SVM according to...
The aim of this study was to develop a prognostic classifier and subdivided the M1 stage for nasopharyngeal carcinoma patients with synchronous metastases (mNPC). A retrospective cohort of 347 mNPC patients was recruited between January 2000 and December 2010. Thirty hematological markers and 11 clinical characteristics were collected, and the association of these factors with overall survival ...
Facial Emotion Expressions plays an important role in interpersonal relations.This is because human convey lot of information visually than verbally.To automate recognition of emotion state,machine should taught to understand facial guestures.In this paper we classify emotion expression through Support Vector Machine(SVM) & Hidden Markov Model (HMM),then Hidden Markov Model is optimized using G...
Data Mining has great scope in the field of medicine. In this article we introduced one new fuzzy approach for prediction of hepatitis disease. Many researchers have proposed the use of K-nearest neighbor (KNN) for diabetes disease prediction. Some have proposed a different approach by using K-means clustering for reprocessing and then using KNN for classification. In our approach Naive Bayes c...
the present study was an attempt to compare the effect of peer metalinguistic corrective feedback on elementary and intermediate efl learners speaking ability to see which level benefits more from this type of feedback. to this end, 117 female efl learners at grade 3, al-zahra high school in kermanshah, iran were non-randomly chosen. the homogeneity of the participants was attained through a pi...
