The property of local parsability allows to parse inputs through inspecting only a bounded-length string around the current token. This in turn enables the construction of a scalable, data-parallel parsing algorithm, which is presented in this work. Such an algorithm is easily amenable to be automatically generated via a parser generator tool, which was realized, and is also presented in the fo...

Walter Zapp was born on 4th September 1905 in Riga. In the 1920s, when he was already living in Estonia, Walter Zapp became fascinated with the idea of developing a small precision camera that would produce pictures with no lesser quality than the considerably bigger cameras. A decade later, in 1936 the first Minox camera prototype was ready. Unfortunately, no producer in Estonia was interested...

We study pricing by multiproduct firms in the context of unregulated monopoly, regulated monopoly and Cournot oligopoly. Using the concept of consumer surplus as a function of quantities (rather than prices), we present simple formulas for optimal prices and show that Cournot equilibrium exists and corresponds to a Ramsey optimum. We then present a tractable class of demand systems that involve...

We introduce a simple local atomic structure optimization algorithm which is significantly faster than standard implementations of the conjugate gradient method and often competitive with more sophisticated quasi-Newton schemes typically used in ab initio calculations. It is based on conventional molecular dynamics with additional velocity modifications and adaptive time steps. The surprising e...

this survey was done for constructing an egg sorting machine which could sort white eggs from fertilized eggs. egg sorting machine was constructed based on physiological properties of trout egg. fertilized eggs have much more elasticity than white or non-hatched eggs. so the hatched eggs will fly back if were hit to a solid surface. the machine divided to 5 parts including mechanical, electrica...

from the political sociology point of view, emerging and continuity of modern societies have been a combined with some kind of totalitarianism in west (as the first step of development), modern nation-states, modern revolutions, modern wars, formation of totalitarian communism-fashism, democratic systems, and at least globalization, terrorism, …. terrorism phenomena has been deep in glomming be...

Genetics have undoubtedly become an integral part of biomedical science and clinical practice, with important implications in deciphering disease pathogenesis and progression, identifying diagnostic and prognostic markers, as well as designing better targeted treatments. The exponential growth of our understanding of different genetic concepts is paralleled by a growing list of genetic terminol...

By separating the principal acceptance mechanism from the concrete acceptance condition of a given Büchi automaton with n states, Schewe presented the construction of an equivalent deterministic Rabin transition automaton with o((1.65n)n) states via history trees, which can be simply translated to a standard Rabin automaton with o((2.26n)n) states. Apart from the inherent simplicity, Schewe’s c...

Dental cementum is a specialized calcified structure covering the root of a tooth. This study aims to investigate cementum using various stains which can be exceedingly useful in investigation, observation and diagnosis. 4µm sections of 25 extracted normal teeth, 25 cases of various cemental pathologies and 25 ground sections were stained using cresyl violet, H/E, toluidine blue and periodic ac...
