Artificial neural network (ANN), pseudo second-order kinetic, and gene expression programming (GEP) models were constructed to predict removal efficiency of Lanaset Red G (LR G) using lentil straw (LS) based on 1152 experimental sets. The sorption process was dependent on adsorbent particle size, pH, initial dye concentration, and contact time. These variables were used as input to construct a ...
In this study, Gene Expression Programming (GEP) is used in modeling the deflection basins measured on the surface of the flexible pavements. Backcalculation of the pavement layer moduli are well-accepted procedures for the evaluation of the structural capacity of pavements. The ultimate aim of the backcalculation process from Nondestructive Testing (NDT) results is to estimate the pavement mat...
AIM To correlate the baseline and change of chromogranin A (CgA) levels with patient survival and tumor response in Asian patients with advanced gastro-enteropancreatic neuroendocrine tumors (GEP-NETs). PATIENTS AND METHODS Sixty patients with advanced GEP-NET treated in a medical center between April 2010 and April 2013 were enrolled retrospectively. Plasma CgA level was analyzed for correla...
This paper describes the application of an evolutionary algorithm, Restart Covariance Matrix Adaptation Evolution Strategy (RCMAES) to the Generation Expansion Planning (GEP) problem. RCMAES is a class of continuous Evolutionary Algorithm (EA) derived from the concept of self-adaptation in evolution strategies, which adapts the covariance matrix of a multivariate normal search distribution. The...
Downlo kground: Although TRIzol is widely used for preservation and isolation of RNA, there is suspicion that ged sample storage in TRIzol may affect array-based gene expression profiling (GEP) through premarmination during reverse transcription. thods: GEP on Illumina arrays compared paired aliquots (cryopreserved or stored in TRIzol) of primary es of multiple myeloma (MM) and acute myeloid le...
پیش بینی مناسب پارامترهای موثر در طرح های مهندسی رودخانه یکی از مهمترین مباحث تحقیقاتی مهندسان هیدرولیک می باشد . از جمله این پارامترها دبی رسوب رودخانه ها است که به دلیل اثرات منفی آن بر کیفیت آب،کاهش ظرفیت مخازن و تغییردرمرفولوژی رودخانه ها ازاهمیت ویژه ای برخوردار است.ارائه روش های مناسب و دقیق در برآرود دبی رسوب رودخانه ها یکی از مهمترین مباحث طراحی و اجرای پروژه های مهندسی مرتبط با فرسایش ...
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are rare, generally indolent neoplasms that can arise throughout the gastrointestinal system. Some GEP-NETs, known as functional, secrete hormones that can lead to a complex of symptoms. Classical carcinoid syndrome is associated with flushing, diarrhea, bronchospasm, and symptoms of valvular heart disease. GEP-NETs are classified accordin...
This paper presents an Election Campaign Optimizat ion (ECO) algorithm for the solution of Generation Expansion Planning (GEP) problem in a competitive electricity market. GEP is one of the important decision-making activities in electric utilit ies and plays a fundamental ro le in the deregulated environment for electricity trading. It is highly constrained non-linear dynamic optimization prob...
Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) are a heterogeneous group of rare tumors whose site-specific tumor incidence and clinical behavior vary widely. Genetic alterations associated with familial inherited syndromes have been well defined; however, the genetic profile of sporadic tumors is less clear as their tumorigenesis does not appear to be controlled by classic oncogenes s...
This article focuses on solving the generalized eigenvalue problems (GEP) arising in the source-free Maxwell equation with magnetoelectric coupling effects that models three-dimensional complex media. The goal is to compute the smallest positive eigenvalues, and the main challenge is that the coefficient matrix in the discrete Maxwell equation is indefinite and degenerate. To overcome this diff...
