in the retinoblastoma research, it is of great interest to identify molecular markers associated with the genetics of tumorigenesis. micrornas (mirnas) are small non-coding rna molecules that play a regulatory role in many crucial cellular pathways such as differentiation, cell cycle progression, and apoptosis. a body of evidences showed dysregulation of mirnas in tumor biology and many disease...

Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...

preventive maintenance scheduling of generating units is addressed as a long-term scheduling in power system studies aiming to increase the reliability incorporating cost reduction. it consists of knowing which generating units should be shut down for regular safety inspection. in this paper, a new formulation of preventive maintenance scheduling associated with cost reduction index (cri) is pr...

the purpose of this study is to study the role of environmental determinants in entrepreneurship in the public sector. this is an applied and descriptive-correlation study. the statistical population is tehran municipality's employees and clients. a sample of 220 municipal employees and a sample of 200 citizens were selected to evaluate the role of environmental factors in entrepreneurship...

This paper explores the properties of daily changes in the prices for near-term fed funds futures contracts. The paper finds these contracts to be excellent predictors of the fed funds rate, and shows that the claim of a nonzero term premium in the short-horizon contracts is more sensitive to outliers than previous research appears to have recognized. I find some statistically significant evide...

A bstract The recent study of holographic superconductors has shown the emergence a Kasner universe behind event horizon. This paper serves to add discussion by introducing two modifications superconductor model: an axion field term and Einstein-Maxwell-scalar (EMS) coupling term. We first discuss effect modification parameters have on condensate then explore black hole interior dynamics. Featu...

l’œuvre n’existe pas en tant que littéraire pour le lecteur, si la lecture ne lui procure aucune émotion esthétique.mais quelles sont les conditions qui président à la perception de l’œuvre comme texte littéraire?et si c’est uniquement le récepteur qui érige le texte en œuvre littéraire, selon quels critères peut-on juger de sa littérarité? pour répondre à ces questions, l’approchesémiostylisti...

Under bond-rate transmission of monetary policy, we show a generalized Taylor Principle requires a lower bound to the average anticipated path of policy responses. This result helps explain the puzzling observation that bond rates appear to exhibit stable responses to inflation, even in periods of passive policy. Another possible explanation is time-varying term premia with risk pricing that de...

Most maintenance-optimisation models assume an in nite planning horizon and suppose that the failure process is stationary. Hence, information which is not known beforehand and which becomes available on the short term only, must be ignored. We consider in this paper a multi-component system with economically dependent components, and we compare the costs of a stationary-planning method with th...
