Although mixed-integer evolution strategies (MIES) have been successfully applied to optimization of mixed-integer problems, they may encounter challenges when fitness evaluations are time consuming. In this paper, we propose to use a radial-basis-function network (RBFN) trained based on the rank correlation coefficient distance metric to assist MIES. For the distance metric of the RBFN, we mod...

In classi"cation tasks it may be wise to combine observations from di!erent sources. Not only it decreases the training time but it can also increase the robustness and the performance of the classi"cation. Combining is often done by just (weighted) averaging of the outputs of the di!erent classi"ers. Using equal weights for all classi"ers then results in the mean combination rule. This works v...

the molecular sieves are selective adsorbents. they can adsorb some kind of molecules that are different in size or shape from the others. in separation of n-paraffins from iso-paraffins and aromatics, sa molecular sieve is the suitable adsorbent, and can adsorb n-paraffins to separate them from other hydrocarbons. in this paper equilibrium isotherms of n-cs, n-c6 and n-c7 from an inert solvent...

Singularly perturbed two-point boundary-value problems (BVPs) for fourth-order ordinary differential equations (ODEs) with a small positive parameter multiplying the highest derivative with a discontinuous source term is considered. The given fourth-order BVP is transformed into a system of weakly coupled systems of two second-order ODEs, one without the parameter and the other with the paramet...

BACKGROUND Fluorodeoxyglucose (18FDG) PET/CT imaging has become an important component of the management paradigm in oncology. However, the significant imparted radiation exposure is a matter of growing concern especially in younger populations who have better odds of survival. The aim of this study was to estimate the effective dose received by patients having whole body 18FFDG PET/CT scanning...

Introduction: Information on the sleepiness and sleep quality is limited for Asians. This study was conducted to determine the prevalence of sleepiness and sleep quality among the adult population in Iran. Materials and Methods: This is a descriptive and explorative design study in which 1100 participants randomly selected from the Kerman city population in South –East of Iran. Using two ques...

In mass casualty events Emergency Medical Service Providers (EMS) choose treatment at Scene or a "scoop and run" approach. The latter requires clinically trained personnel at the reception site to triage patients. Current methodology based on Revised Trauma Score (tRTS) requires use of Glasgow Coma Scale, a method reliant on experience and clinical knowledge. This makes the system subjective an...

OBJECTIVES The aim of this study was to evaluate the validity and reliability of the Japanese version of the painDETECT questionnaire (PDQ-J). MATERIALS AND METHODS The translation of the original PDQ into Japanese was achieved according to the published guidelines. Subsequently, a multicenter observational study was performed to evaluate the validity and reliability of PDQ-J, including 113 J...

background: the 21st century is faced with increase in challenges of urban population and aging. according to statistics, the old population in the world and in iran is increasing. obviously, their health promotion is the concern of the community and achieving it requires purposeful planning. being healthy means to feel good in social, mental, and physical dimensions (definition by the world he...

BACKGROUND Postlaunch data on medical treatments can be analyzed to explore adverse events or relative effectiveness in real-life settings. These analyses are often complicated by the number of potential confounders and the possibility of model misspecification. METHODS We conducted a simulation study to compare the performance of logistic regression, propensity score, disease risk score, and...
