Evolutionary Programming (EP) seems a promising methodology to automatically find programs to solve new computing challenges. The Evolutionary Programming techniques use classical genetic operators (selection, crossover and mutation) to automatically generate programs targeted to solve computing problems or specifications. Among the methodologies related with Evolutionary Programming we can fin...

Traditional investigations with evolutionary programming (EP) for continuous parameter optimization problems have used a single mutation operator with a parameterized probability density function (pdf), typically a Gaussian. Using a variety of mutation operators that can be combined during evolution to generate pdf’s of varying shapes could hold the potential for producing better solutions with...

This paper presents an online demo of evolutionary programming using a mixed mutation strategy for solving function optimization problems. The strategy combines three different mutation operators: Gaussian, Cauchy and Lévy mutations. The algorithm has been implemented by a client-server web application, which is convenient for users to access through Internet. The web application architecture i...

Fabrication and electrochemical characterization of a sensor for the determination of epinephrine (EP), uric acid (UA) and folic acid (FA) is described. The sensor  was prepared using carbon paste electrode (CPE) modified with 3,4-dihydroxybenzaldehyde-2,4-dinitrophenylhydrazone (DDP) and carbon nanotubes (CNTs), which makes the modified electrode highly sensitive for the electrochemical detect...

background: one of the affecting factors in disturbance process of spermatogenesis is chemotherapeutic-induced oxidative stress resulted from cyclophosphamide (cp) treatment which leads to diminished sperm quality via interference in spermatogenesis process. objective: this study was conducted to investigate the effects of ethyl pyruvate (ep) in reducing the cp-induced side effects on reproduct...

background: measurement of serum β-hcg concentration commonly used to diagnose tubal ectopic pregnancy (ep) and follow up patients treated conservatively.objective: the aim of this study was to determine the predictive value of maternal serum β-hcg concentration in ruptured tubal ectopic pregnancy to help physicians identify those women who are at greatest risk.materials and methods: this is a ...

In this paper, a nanostructured modified electrode was fabricated by incorporating of 2,2′-[1,9-nonanediylbis(nitriloethylidyne)]-bis-hydroquinone (NNH) as a newly synthesized modifier and TiO2 nanoparticles to the carbon paste (MTCPE) and then was used for the electroanalysis of epinephrine (EP). The electrochemical studies were carried out by using cyclic voltammetry, chronoamperom...

Four E-prostanoid (EP) receptors, designated EP(1), EP(2), EP(3), and EP(4), mediate the cellular effects of prostaglandin E(2) (PGE(2)). The present studies pharmacologically characterize the vasopressor and vasodepressor EP receptors in wild-type mice (EP(2)(+/+) mice) and mice with targeted disruption of the EP(2) receptor (EP(2)(-/-) mice). Mean arterial pressure (MAP) was measured via a ca...

Evolutionary programming (EP) has been applied with success to many numerical and combinatorial optimization problems in recent years. EP has rather slow convergence rates, however, on some function optimization problems. In this paper, a “fast EP” (FEP) is proposed which uses a Cauchy instead of Gaussian mutation as the primary search operator. The relationship between FEP and classical EP (CE...

While some researchers have questioned the efficacy of corrective feedback (CF), other researchers believe that CF can be effective if implemented through new technology types, including e-portfolio (EP). However, whether EP can be used as a medium of providing CF for language learners at different levels of language proficiency is still unknown. The purpose of the present study, therefore, was...
