introduction: stroke is recognized as the third cause of mortality after cardiovascular and cancer diseases, so that lead to death of about 5 million people, annually. there are several scales to early prediction of at risk patients and decreasing the rate of mortality by transferring them to the stroke center. in the present study, the accuracy of cincinnati pre-hospital stroke scale was asses...
in this paper, a new approach is proposed in order to select an optimal membership function for inputs of wind speed prediction system. then using a fuzzy method and the stochastic characteristics of wind speed in the previous year, the wind speed modeling is performed and the wind speed for the future year will be predicted. in this proposed method, the average and the standard deviation of in...
this was a prospective cross-sectional study of consecutive transported patients by emergency medical service (ems) to a referral hospital. the goal of this study was the evaluation of emergency medical technician intermediate prediction about their transported patients disposition in emergency department of imam khomeini hospital. 2950 patients were transported to this hospital, questionnaires...
abstract background: clinical risk index of babies (crib), score for neonatal acute physiology (snap), an update of the clinical risk index for babies score (crib ii) and score for neonatal acute physiology - perinatal extension (snap-pe) are scoring devices developed in neonatal intensive care units. this study reviewed these scoring systems in critically ill neonates to determine how well the...
Perceptron based predictors are highly accurate. This high accuracy is the result of exploiting long history lengths [1] and is achieved at the expense of high complexity. The dot product of two vectors is used as prediction. The first vector is the branch outcome history where the second vector is composed of per branch weights, which represent the correlation between branch outcome and previo...
Preterm delivery is the main cause of perinatal morbidity and mortality throughout the world. Many complications such as neonatal intraventricular hemorrhage, cerebral palsy and high cost have increased the importance of preterm delivery therefore, it is important to detect high risk women early in pregnancy in order to prevent this problem. All of the methods used for preterm deliv...
Lots of similarity-based algorithms have been designed to deal with the problem of link prediction in the past decade. In order to improve prediction accuracy, a novel cosine similarity index CD based on distance between nodes and cosine value between vectors is proposed in this paper. Firstly, node coordinate matrix can be obtained by node distances which are different from distance matrix and...
introduction: percutaneous transluminal coronary angioplasty (ptca) is an effective method for revascularizing of stenotic coronary vessels. lack of response to this treatment, either in symptomatic or asymptomatic patients, is usually due to incomplete revascularization, restenosis, and/or irreversibility of myocardial perfusion. introduction of a noninvasive method with high predictive value ...
BACKGROUND A major problem of the first moments of childbirth, especially in "prolonged labor," is perinatal asphyxia which necessitates neonatal resuscitation. This study aimed at evaluating the alert line of the partogram in recognizing the need for neonatal resuscitation 20-30 s after delivery. MATERIALS AND METHODS 140 full-term pregnant women were kept under surveillance through using a ...
