We discuss construction of classical time dependent solutions in open string (field) theory, describing the motion of the tachyon on unstable D-branes. Despite the fact that the string field theory action contains infinite number of time derivatives, and hence it is not a priori clear how to set up the initial value problem, the theory contains a family of time dependent solutions characterized...
We study the branch of semi-stable and unstable solutions (i.e., those whose Morse index is at most one) of the Dirichlet boundary value problem −∆u = λf(x) (1−u)2 on a bounded domain Ω ⊂ R , which models –among other things– a simple electrostatic Micro-Electromechanical System (MEMS) device. We extend the results of [11] relating to the minimal branch, by obtaining compactness along unstable ...
since its introduction in 1959, translation quality assessment (tqa) has been among the most addressed research topics in translation studies. during recent years, there has been a crucial increase on the study of tqa. various methods have come on scene. although these methods are based on scientific theories, most of them have remained at the level of theory. juliane house’s model is among tho...
We prove a consistency results saying, that for a simple (first order) theory, it is easier to have a universal model in some cardinalities, than for the theory of linear order. We define additional properties of first order theories, the n-strong order property (SOPn in short). The main result is that a first order theory with the 4-strong order property behaves like linear orders concerning e...
Genes vary greatly in their long-term phylogenetic stability and there exists no general explanation for these differences. The cytochrome P450 (CYP450) gene superfamily is well suited to investigating this problem because it is large and well studied, and it includes both stable and unstable genes. CYP450 genes encode oxidase enzymes that function in metabolism of endogenous small molecules an...
Islamic texts have significant capacities in various fields of human knowledge. Among the issues raised in these religious texts is architecture and its features that on this basis, till now, some researches have been done on the Islamic architecture. One of the main problems which have been considered during recent decades (especially in the field of urban development) is development pattern ...
“any science seeks generalities; the aim is to transcend knowledge of particular cases by discovering general regularities or laws” (chesterman, 2001, p. 1). these were the words of chesterman whose paper has served as a typical example of numerous papers carried out on ‘translation universals’ since the mid-nineties. blum-kulka (1986) is among translation studies scholars who proposed ‘explici...

background & objectives: regional planning requires identification of the development status of regions relative to each other. one of the indicators of development is health indicator that describes utilization of health services in the society. the purpose of this study is to analyze health indicators status in ardabil province and prioritize them for future planning. methods: based on practi...
The behavior of a laboratory-scale pulsed combustor is shown to undergo a global bifurcation as the equivalence ratio of the propane-air mixture is reduced toward the lean flammability limit. At near-stoichiometric and moderately lean conditions, the acoustically driven combustion oscillations exhibit small, stochastic cycle-tocycle variations. At very lean conditions, the available fuel invent...
