tax , as the most initial and most important public revenue , principally plays an important role in providing public expenses and for this purpose, it enjoys an extraordinarily higher place for all states in the world. in this way in tax laws that are currently enforced in all states including iran, special rights and powers have been granted to tax organization in order to allow it to carry o...

In present paper, vibration of Nano FGM plate based on modified couple stress and First Order Shear Deformation Theories (FSDT) under moving load has been developed. Basic equations and linear strains are introduced by first order shear deformation theory and Mori Tanaka’s model is used for the plate. The module of elasticity and density are assumed to vary only through thickness of plate. Gove...

The mathematical modelling of signal transduction pathways has become a valuable aid to understanding the complex interactions involved in intracellular signalling mechanisms. An important aspect of the mathematical modelling process is the selection of the model type and structure. Until recently, the convention has been to use a standard kinetic model, often with the Michaelis-Menten steady s...

The radius of gyration is a fundamental structural parameter that is particularly useful for describing polymers. It has been known since Flory's seminal work in the mid-20th century that polymers show a power-law dependence, where the radius of gyration is proportional to the number of residues raised to a power. The power-law exponent has been measured experimentally for denatured proteins an...

this paper introduces an indirect adaptive fuzzy sliding mode controller as a power system stabilizer for damping local and inter-area modes of oscillations of multi-machine power systems. this controller is designed based on the combination of sliding mode controller and the fuzzy logic systems. the fuzzy systems are used to approximate the unknown functions of power system model. generator sp...

Using a measure of how differentially expressed a gene is in two biochemically/phenotypically different conditions, we can rank all genes in a microarray dataset. We have shown that the falling-off of this measure (normalized maximum likelihood in a classification model such as logistic regression) as a function of the rank is typically a power-law function. This power-law function in other sim...

We propose a new method for estimating the power-law exponents of firm size variables. Our focus is on how to empirically identify a range in which a firm size variable follows a power-law distribution. As is well known, a firm size variable follows a power-law distribution only beyond some threshold. On the other hand, in almost all empirical exercises, the right end part of a distribution dev...

The PRC enterprise income tax law was enacted on January 1, 2008, with accordance to which the enterprise income tax law system has been changing. It took a long time to promulgate the law just as it takes and will take certain period to integrate the system from the constitutional law to tax polices. The lack of taxing power under constitutional law, the silence of a basic tax law, and the arb...

The benefits from practice follow a nonlinear function: Improvement is rapid at first but decreases as the practitioner becomes more skilled (see, e.g., Thorndike, 1913). The idea that a simple nonlinear function might describe practice effects in a broad range of tasks was championed by Newell and Rosenbloom’s (1981) influential chapter entitled “Mechanisms of Skill Acquisition and the Law of ...
