In n-tuple Zipf analysis, ‘‘words’’ are defined as strings of n digits, and their normalized frequency of occurrence v is measured for a given ‘‘text’’ ~sequence of digits!. In the case of various non-Markovian sequences, the probability density of the frequencies P(v) has a power-law tail. Here we argue that a broad class of unbiased binary texts exhibiting a nonexponential distribution of clu...

in order to determine the appropriate plant density in different planting dates for sweet corn cultivar ksc403su, an experiment was conducted using a randomized complete block design in split plot lay out with three replications at seed and plant improvement institute in karaj in 2006. three planting dates (22 may, 5 june and 22 june) were assigned as main plots and three plant densities (65000...

We discuss the implications of the recent upward revision of the LMC microlensing rate by the MACHO Collaboration. We conclude: (i) A good case for the existence of baryonic dark matter in the halo has been made; (ii) The case for the existence of cold dark matter is unaffected and still compelling; and (iii) The Galactic halo is still an excellent place to search for cold dark matter particles...

The dilator function of the vascular endothelium is critical for optimal tissue perfusion, and this is brought into stark reality in a number of diseases, such as hypertension, diabetes, and preeclampsia, in which endothelium-dependent vasodilator function is impaired. Prostacyclin and nitric oxide (NO) were the earliest identified endothelium-dependent vasodilators, but it was soon found that ...

An anticipatory system for guiding plot development in interactive narratives is described. The executable model is a finite automaton that provides the implemented system with a lookahead. The identification of undesirable future states in the model is used to guide the player, in a transparent manner. In this way, too radical twists of the plot that lead to behaviors of the autonomous fellow ...

BACKGROUND In meta-analysis, the presence of funnel plot asymmetry is attributed to publication or other small-study effects, which causes larger effects to be observed in the smaller studies. This issue potentially mean inappropriate conclusions are drawn from a meta-analysis. If meta-analysis is to be used to inform decision-making, a reliable way to adjust pooled estimates for potential funn...
