‎Multivariate normal-Poisson model has been recently introduced as a special case of normal stable Tweedie models‎. ‎The model is composed of a univariate Poisson variable‎, ‎and the remaining variables given the Poisson one are independent Gaussian variables with variance the value of the Poisson component‎. ‎Two characterizations of this model are shown‎, ‎...
Analyzing medical images is the most challenging task in medical image processing. Computer Aided Detection (CAD) tool is the aid for the radiologists in analyzing such images for the effective detection and diagnosis of the disease. Such a CAD tool consists of Preprocessing, Segmentation and detection processes. In this study we have improved the preprocessing by using the Selective Median Fil...
Background & Aims: Magnetically molecularly imprinted polymers (MMIPs) are assumed as kind of sorbent polymers ‎which can separate or determine bioactive compounds from environment fast and specifically. ‎Magnetic properties, stability at various conditions (temperature , ionic strength and pH) and selective ‎function are among the advantages of these polymers in determin...
Introduction: Nurses are the largest care delivering group. They have to judge in clinical ‎setting and by team work detect and solve patients’ problem in nursing function domains. ‎Collaboration in decision making helps this function. ‎ Objective: Present study aims to determine the level of nurses’ collaboration in clinical ‎decision making employed in edu...
In this paper, we propose an approach for the nonparametric estimation of the conditional survival function of a time to failure‎ ‎given a time-varying covariate under interval-censoring for the failure time. Our strategy consists in‎ ‎modeling the covariate path with a random effects model, ‎as is done in the degradation and joint longitudinal and survival data modeling&lrm...
Introduction:‎‏ ‏Prompt start of complementary food and mothers' knowledge regarding it is ‎very important for the child’s nutritional status.‎ Objective: The purpose of this study was to assess infants' pattern of complementary food ‎and nutritional knowledge of mothers in rural areas in Rasht city.‎ Methods: In a cross-sectional study in summer of ‎‏2...
A number of sediment quality guidelines (SQGs) have been developed for relating chemical concentrations in sediment to their potential for effects on benthic macroinvertebrates, but there have been few studies evaluating the relative effectiveness of different SQG approaches. Here we apply 6 empirical SQG approaches to assess how well they predict toxicity in California sediments. Four of the S...
Medical science experts have reached scientific and technological improvements in recent ‎decades and have turned surgery into a routine treatment by controlling its complications. ‎Cumulative changes in surgery resulted in decreased pain and discomfort and controlled ‎complications. The developmental path and changes have resulted in endoscopic with minimal ‎invasive surgery (M...
Introduction: Anxiety is one of the most common reactions to stressors and ‎hospitalized children confront it and playing is a priority care to reduce stress.‎ Objective: The present study was conducted to determine the effect of playing on the ‎level of anxiety in school- age children hospitalized in educational pediatric centers ‎in Rasht city.‎ Methods: This is a qu...
Introduction: Progressive facial hemiatrophy (Parry-Romberg syndrome) is a rare disease ‎always with neurological symptoms such as migraine and epilepsy. Parry-Romberg syndrome ‎is determined with progressive slow hemiatrophy of skin and soft tissue structures in face and ‎frequently in left face. Disease is more common in females. The objective of this paper is to ‎present a ca...
