Objectives This research was conducted with the goal of comparison of executive functions, risk behaviors, and academic motivation among adolescents with chronology type morningness and eveningness. Methods This is a comparative study in a population of high school students in Isfahan in 2014-15 academic year. Accessible sampling was used as a sampling method in two phases. In the first phase ...

Research indicates a distinction between the processing of script content (which events, behaviors, scenes… are part of it) and script chronology (what is their usual order of occurrence). Using sequences of two line drawings depicting everyday social script events, we examined the event related potential (ERP) correlates of script chronology violations (i.e., wrong order). An increased left an...

The number of Neolithic sites in Fars greatly increases in the pottery Neolithic period. How this pattern indicates the high capability of pottery Neolithic period of Fars is not clear yet. Even though a definite path to the growth of indices of Neolithic settlement patterns in Fars during the seventh and sixth millennium B.C. has been recommended which may indeed be true, for this period we ca...

When Saturn was the only known ringed planet, the rings were believed to be as old as the solar system, some 4.5 billion years old in the conventional chronology. The existence of the rings to the present day was taken as evidence of this chronology. In the 1970s and 1980s, other planets were found to have shortlived, rapidly dissipating rings with life times of the order of millennia. Subseque...

We present data on the O2/N2 ratios of trapped gas samples for the entire length of the Vostok climate record. As in other cores, O2/N2 ratios in these samples are less than the atmospheric ratio, by a small and variable amount, because O2 is selectively excluded during the gas trapping process, and because O2 is also preferentially lost in poorly preserved core samples. Samples younger than 15...

This paper introduces a new empirical strategy for the characterization of business cycles. It combines non-parametric decoding methods that classify a series into expansions and recessions but does not require specication of the underlying stochastic process generating the data. It then uses network analysis to combine the signals obtained from di erent economic indicators to generate a uniqu...

Quantum complex scalar field in the two-dimensional spacetime with closed timelike curves and a time-machine problem Abstract It is considered the quantum complex scalar field which obeys the authomorphic condition in the two-dimensional spacetime with closed timelike curves and the chronology horizon. The renormal-ized stress-energy tensor is obtained. It is shown that the value of the stress-...
