BACKGROUND Gold nanoparticles are emerging as promising agents for cancer therapy and are being investigated as drug carriers, photothermal agents, contrast agents and radiosensitisers. OBJECTIVE The aim of this study is to understand characteristics of secondary electrons generated from interaction of gold nanoparticles GNPs with x-rays as a function of nanoparticle size and beam energy and ...

This paper describes a hybrid stock trading system based on Genetic Network Programming (GNP) and Mean Conditional Value-at-Risk Model (GNP–CVaR). The proposed method, combining the advantages of evolutionary algorithms and statistical model, has provided useful tools to construct portfolios and generate effective stock trading strategies for investors with different risk-attitudes. Simulation ...

FIROUGHOUT 1989, popular wisdom held that the U.S. monetary authority was faced with a daunting policy task: it should not permit too much money growth and cause prices to rise too rapidly, but it should not allow too little money growth and cause the economy to tip into recession as real output would fall. Sympathy for monetary policymakers, however, is not necessarily widespread among economi...

Tribological performance of polyalphaolefin 32, PAO, is investigated by adding two nanomaterials (graphene nanoplatelets, GnP, and hexagonal boron nitride nanoparticles, h-BN) an ionic liquid ([P 6,6,6,14 ][DEHP], IL1, [P 2,4,4,4 ][DEP], IL2, or ][(iC8) 2 PO ], IL3). Designed double hybrid nanodispersions are PAO/1 wt% ILX/0.05 GnP/0.1 h-BN (X = 1, 3). The best anti-friction behavior correspond...

Evolutionary Computation is well-known for producing the solutions in optimization problems based on change, composition and selection. We have proposed Genetic Network Programming (GNP) [1, 2] as an extended method of Genetic Algorithm (GA) [3, 4] and Genetic Programming (GP) [5, 6]. It has been clarified that GNP is an effective method mainly for dynamic problems since GNP represents its solu...

This study examined the gene transfer efficiency and toxicity of 2-kDa polyethylenimine conjugated to gold nanoparticles (PEI2-GNP) in the human cornea in vitro and rabbit cornea in vivo. PEI2-GNP with nitrogen-to-phosphorus (N/P) ratios of up to 180 exhibited significant transgene delivery in the human cornea without altering the viability or phenotype of these cells. Similarly, PEI2-GNP appli...

This paper describes electrochemical synthesis of nanorods of tetrathiafulvalene (TTF) charge-transfer salt on gold nanoparticle (GNP) seeds. The seed-mediated process was monitored by cyclic voltammetry, AFM, and field-emission SEM. The electrodeposition of GNPs (nucleation seeds) on highly oriented pyrolytic graphite (HOPG) electrodes was studied as a function of the electrolytic conditions. ...

In this study, we quantify the relative damage enhancement due to the presence of gold nanoparticles (GNP) in vitro in a clinical 6 MV beam for various delivery parameters and depths. It is expected that depths and delivery modes that produce a larger proportions of low-energy photons will have a larger effect on the cell samples containing GNP. HeLa cells with and without 50 nm GNP were irradi...

The catalytic reduction of 4-nitrophenol is considerable importance to a multitude applications and industries. present work introduces new catalyst (AuNP/GNP/MgAl-LDH) containing gold nanoparticles (AuNP) supported on graphene nanoplatelets (GNP) intercalated in Mg Al layered double hydroxides (MgAl-LDH) for the 4-aminophenol using NaBH4 as reducing agent. was characterised by FTIR, XRD, STEM,...

This article reports the findings of a study developed to compare health care costs in the United States with those of eight other industrially advanced countries over the period 1960-76. All of the countries studied were found to share with the United States the problem of increased health care spending that has outpaced inflation in other sectors of the economy and continues to consume a grow...
