Given a graph whose nodes may be coloured red, the parity of number red can easily maintained with first-order update rules in dynamic complexity framework DynFO Patnaik and Immerman. Can this generalised to other or even all queries that are definable logic extended by quantifiers? We consider query asks whether have an edge node is odd. Already simple quantifier structure parity-exists major ...

Studies of the muscle force-velocity relationship and its derived n-shaped power-velocity curve offer important insights into muscular limits of performance. Given the power is maximal at 1/3 V(max), geometric scaling of muscle force coupled with fluid drag force implies that this optimal muscle-shortening velocity for power cannot be maintained across the natural body-size range. Instead, musc...

This study examines dynamic interrelationships and causality relationships among CO2 emissions, economic, political and financial variables over the period of 1971-2011 for the case of Iran as one of the top CO2 emitting countries in the world. The results of ARDL and Johansen cointegration approaches confirm the existence of long run relationship among CO2 emissions, energy consumption, GDP, f...

this research aims to investigate relationship between skewness and future stock return and the impact of information releases on this relationship. then, the data of 89 companies listed in tehran stock exchange are collected and analyzed for 2009 to 2013. furthermore, the fixed effect panel data method is used to examine the hypothesis. the results show that there exists a negative and signifi...

A distribution with high spatial variability may impair the bet-hedging capacity of a population, threatening population sustainability. Although association between aggregation and life history traits species (e.g. body size) has been documented, relationship size within rarely explored. As selective over-fishing induce truncation in targeted stocks, it is critical to understand if such also u...
