This paper summarizes a new approach that we recently proposed for ranking and selection problems, one that maximizes the expected NPV of decisions made when using stochastic or discrete-event simulation. Our formulation assumes that facilities exist to simulate a fixed number of alternative projects, and we pose the problem as a “stoppable” version of a Bayesian bandit problem. Under relativel...

A composite material comprising randomly distributed spherical particles of two different isotropic dielectric–magnetic materials is homogenized using the second–order strong– property–fluctuation theory in the long–wavelength approximation. Whereas neither of the two constituent materials by itself supports planewave propagation with negative phase velocity (NPV), the homogenized composite mat...

Objective: To validate Mentzer Index as a screening tool for Iron Deficiency Anemia (IDA) in 6 to 12 years old children. Methodology: This cross-sectional validation study was conducted at the Department of Pediatrics, Combined Military Hospital, Peshawar and Khyber Teaching from February 2021 January 2022. Following set inclusion exclusion criteria, sample 419 participants were enrolled using ...

Following this discussion of the inferences that can be formed from using IRR and NPV comes a description further steps should done as direct result those inferences. These additional taken since they are directly related to premises. It is strongly recommended these actions carried out conclusions have been formed. As result, it will guide decision whether or not invest in agricultural sector....

Background: Hirschsprung's disease is the most common cause of pediatric intestinal obstruction. Contrast enema is used for evaluation of the patients with its diagnosis. Aim: To evaluate sensitivity, specificity, positive predictive value, and negative predictive value of radiologic findings for diagnosis of Hirschsprung in patients underwent barium enema. Methods: This cross sectional s...

A model was developed for the economic evaluation of embryos for producing bull lines for use in commercial beef production. The fundamental concept underlying the model is that a cloned and sexed embryo of known genetic characteristics for beef traits is used to produce a bull. After reaching physiological maturity, the bull is used in natural matings. Equations relating feed energy requiremen...

OBJECTIVE This study tried to assess sensitivity, specificity, positive and negative predictive value of procalcitonin for diagnosis of neonatal bacterial infections. METHODS This prospective cross sectional study was carried out during an 18-month period in NICU and neonatal wards of Besat Hospital in Hamedan province, Iran. 39 symptomatic infants with clinical and laboratory findings in fav...

Background/Aims Balloon expulsion test (BET) is regarded as a screening tool of dyssynergic defecation (DD). However, some patients with normal BET results may be treated effectively by biofeedback training. This study aims to validate BET as a single screening test. Methods Two hundred and thirty-two patients who were diagnosed with functional constipation or irritable bowel syndrome with co...
