Genetic network programming (GNP) as an evolutionary computation method has been used for stock trading recently. Former researches confirm the efficiency of trading rules which are created by GNP. In this paper, GNP has been applied for stock portfolio optimization by generating risk-adjusted trading rules. There are two main novelties in this paper: 1) we use conditional Sharp ratio as a risk...

Friction and wear are responsible for around 23% of the energy consumption in transportation, manufacturing, power generation, residential sectors. Employed components exposed to a wide range operational conditions, therefore suitable material design is fundamental decreasing tribological issues, consumption, costs, environmental impact. This study aims analyze effect different solid lubricants...

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...

The initiative of Indian Government to allow 100% FDI in single brand retailing and 51% in multi brand retailing has, with a few affirmations, raised many eye brows. Is it recolonization in the post independence era or a class struggle in the words of Karl Marx? This paper attempts at studying the economic effect of ‘FDI in retail’ on various sectors of the economy drawing the cue from the expe...

We developed a simple monetary model to study the effects of tax evasion on the optimal inflation tax. The model is constructed so that inflation might be an indirect way of taxing the underground sector of the economy. We show that while there are theoretical reasons for positive optimal inflation rates, the effects are quantitatively small, even in countries with large underground sectors. We...

Purpose: In radiation therapy, gold nanoparticles (GNPs) are regarded as a promising radiosensitizer candidate. Several studies have revealed a dose enhancement by GNPs in X-ray and even proton irradiation. However, these studies have been limited to the depth direction. The dose distribution in both depth and lateral directions is crucial to evaluate the full radio sensitizing effect. The purp...

A label-free method is developed to ratiometrically determine the stoichiometry of oligonucleotides attached to the surface of gold nanoparticle (GNP) by whispering gallery mode biosensing. Utilizing this scheme, it is furthermore shown that the stoichiometric ratio of GNP attached oligonucleotide species can be controlled by varying the concentration ratio of thiolated oligonucleotides that ar...

Limited efficacy of current first-line treatment for leukemia calls attention for further development of efficient strategies. Recently, much attention has been given to nanoparticle-based drug delivery systems loaded with dual drugs to improve current disease therapies by overcoming toxicity. In the present study, we document to explore an approach to conjugate gold nanoparticles (GNPs) with p...
