hemoglobin is a tetrameric oxygen transport protein in animal bodies. however, there is a paucity of information regarding differences between alpha and beta subunits of hemoglobin in terms of oxygen affinity. the sequential model of koshland, nemthy and filmer (knf model) has attributed similar affinities to both alpha and beta subunits. the main purpose of the present study is to construct a ...

The growth of regional trade blocks has been one of the major developments in international relations in recent years. Regional agreements vary widely but, all have the objective of reducing barriers to trade between member countries that in most cases result in increasingly trade flows and economic growth. This paper attempts to explore the results of trade integration in ECO, EU and OIC block...

The present paper analyzes the existence of a long-run relationship between the trade balance and exchange rate of Iran and South Korea by a new approach. It proposes an asymmetric co-integrating NARDL model by two positive and negative partial sum decompositions which can use mixed I (0) and I (1) variables by bounds testing approach. The proposed tests are based on calculated F –statistics an...

The relationship between technology and international competitiveness dates back to the neo-technological trade theories of the 1960s. This approach considers difference in technology as the primary motive for difference among nations in terms of trade performance. The technology gap approach emphasizes inter-country differences in innovativeness as the basis for international trade flows. The ...

This article has considered the volume and direction of Iran’s trade using the gravity model. The major issue in this analysis is to explore why Iran over or under-traded with the 76 countries relative to the predicted trade flows of the model. The study attempts to explore the reasons from the respect of both the model itself and Iran’s trade structure. This is done by analysing the performanc...

Objective: The aim of this study is to model arrival process of informed and uninformed traders into Tehran Stock Exchange (TSE) as well as to assess the interaction between two types of traders which is an important yet neglected topic. Methods: In this study, a sequential trade model was estimated based on trading data of 33 stocks belonging to 11 industries of TSE during the period from 201...

The extraction of information from a quantum system unavoidably implies a modification of the measured system itself. In this framework partial measurements can be carried out in order to extract only a portion of the information encoded in a quantum system, at the cost of inducing a limited amount of disturbance. Here we analyze experimentally the dynamics of sequential partial measurements ca...

This paper presents an environment in which firms’ productive heterogeneity passes through to wage dispersion via sequential search and endogenous worker effort levels. Despite small gains from trade, the model is able account for more than two thirds of the measured firm component of wage dispersion. The implied narrow range of worker utility effectively pins down the lowest wage in the distri...

all practical digital circuits are usually a mixture of combinational and sequential logic. flip–flops are essential to sequential logic therefore fuzzy flip–flops are considered to be among the most essential topics of fuzzy digital circuit. the concept of fuzzy digital circuit is among the most interesting applications of fuzzy sets and logic due to the fact that if there has to be an ultimat...
