Recently, multi-time stepping methods have become very popular among scientist due to their high stability in problems with critical conditions. One important shortcoming of these methods backs to their high amount of uncontrolled amplitude decay. This study proposes a new multi-time stepping method in which the time step is split into two sub-steps. The first sub-step is solved using the well-...

in this paper by using the data related to the monthly precipitation of 13 stations situated in west azerbaijan province of iran in a time period of 34 years, monitoring and forecasting the probability of a drought occurrence is evaluated in next coming months. in this process, first the monthly precipitation amounts for each rainfall station are used in order to calculate the standardized prec...

Modular organization in control architecture may underlie the versatility of human motor control; but the nature of the interface relating sensory input through task-selection in the space of performance variables to control actions in the space of the elemental variables is currently unknown. Our central question is whether the control architecture converges to a serial process along a single ...

College students, especially women, demonstrated negativity toward math and science relative to arts and language on implicit measures. Group membership (being female), group identity (self female), and gender stereotypes (math male) were related to attitudes and identification with mathematics. Stronger implicit math male stereotypes corresponded with more negative implicit and explicit math a...

OBJECTIVE Nightmares are a robust and modifiable predictor of increased suicidality and poor psychiatric outcomes, yet nightmare screening and treatment remain rare, even in sleep centers. This paper aims to examine what proportion of nightmare sufferers have discussed nightmares with a healthcare provider, as well as possible explanations for low rates of nightmare complaints. METHODS The pr...

But the Lord came down to see. .. the tower which the sons of men had built. And the Lord said, ''Indeed the people are one and they all have one language, and this is what they begin to do;. .. Come, let Us go down and there confuse their language, that they may not understand one another's speech.''. .. Therefore its name is called Babel, because there the Lord confused the language of all th...

When not performing a task, we are usually engaged in a variety of thoughts, for instance about current problems, opportunities, our self-image, our relationships, about past experiences, and about plans for the future. Such mind wandering was found to occupy almost half of our time spent awake (Killingsworth and Gilbert, 2010). Mind wandering may have had the evolutionary advantage of better a...

Abstract. Given a doubling measure μ on R, it is a classical result of harmonic analysis that Calderón-Zygmund operators which are bounded in L(μ) are also of weak type (1, 1). Recently it has been shown that the same result holds if one substitutes the doubling condition on μ by a mild growth condition on μ. In this paper another proof of this result is given. The proof is very close in spirit...
