We study the variation of word frequencies in Russian literary texts. Our findings indicate that the standard deviation of a word’s frequency across texts depends on its average frequency according to a power lawwith exponent 2 < α < 1, which shows that the rarer words have a relatively larger degree of frequency volatility (that is, higher ‘‘burstiness’’). A latent factor model has been estima...
As a case-study in machine-checked reasoning about the complexity of algorithms in type theory, we describe a proof of the average-case complexity of Quicksort in Coq. The proof attempts to follow a textbook development, at the heart of which lies a technical lemma about the behaviour of the algorithm for which the original proof only gives an intuitive justification. We introduce a general fra...
MOTIVATION One of the primary aims of the structural genomics initiative is the determination of representative structures from each protein fold family. Given this objective, it is important to rapidly identify proteins that belong to a family that is already well populated (so they can be eliminated from further studies), or more importantly identify proteins that represent new families of fo...
in his last years of life americans had almost forgotton steinbeck, and those who had not, occasionally criticized him for supporting and praising the u. s. military intervention in the vietnam war. althought ateinbeck incorporates different themes into his works, each one bears many signs of his concern and sympathy for america and the american common people in particular. steinbecks to a god ...

abstract this paper discusses several commonly used models for strategic marketing¹ including market environmental analysis methods (i.e. swot and pest analysis) and strategic marketing tools and techniques (i.e. boston matrix and shell directional policy matrix)and shows how these models may help a firm to achieve its strategic goals. at first, the main reason for doing this research is de...
We have measured the time average spatial intensity distribution and the spatio-temporal evolution of the spectrally Ž . resolved radiation emitted from broad-area vertical cavity surface emitting lasers VCSEL when pumped by a fast current pulse. We show that an intrinsic symmetry break exists due to geometrical asymmetry of the device structure and that the frequency separation between differe...
