We introduce a two generated weakly branch contracting automaton group $G$ which is generated by a two state automaton on a three letter alphabet. Using its branch structure and the finiteness nature of a sequence of its factor groups we compute the order of some of these factors. Furthermore some algebraic properties of $G$ are detected .

one of the reasons that companies avoid paying their taxes is that they choose to use debts for their funding. in other words, tax saving, an activity of companies to avoid taxpaying, can be used to finance corporate projects. furthermore, since institutional owners are more inclined to supervise, they may shrink managerial behaviors to avoid taxpaying. in this study, institutional owners’ supe...

In this paper, a photonic crystal structure for comparing two bits has beenproposed. This structure includes four resonant rings and some nonlinear rods. Thenonlinear rods used inside the resonant rings were made of a doped glass whose linearand nonlinear refractive indices are 1.4 and 10-14 m2/W, respectively. Using Kerr effect,optical waves are guided toward the correc...

anthony giddens, a prominent social theoretician of contemporary sociology, has done extensive theoretical efforts in the last three decades. central to his debates is the theory of structuration, which was first introduced in his book constitution of society (1984). the theory, aimed at giving an end to dominance of hermeneutic theories on the one hand and structuralism and functionalism on th...

introduction: the horizontal bony canal in the lateral maxillary wall is the site of anastomosis between the arterial branches from the posterior superior alveolar artery (psaa) and the infraorbital artery. this anatomic structure is known as the ‘alveolar antral artery’.   materials and methods: we performed a literature review. the anatomic location of the alveolar antral artery in the latera...

In this paper, we propose and evaluate a novel design of a lightly doped drain and source carbon nanotube field effect transistor (LDDS-CNTFET) with a negative differential resistance (NDR) characteristic, called negative differential resistance LDDS-CNTFET (NDR-LDDS-CNTFET). The device was simulated by using a non equilibrium Green’s function method. To achieve this phenomenon, we have created...

one of the chief discussions within the phrase structure theory is the analysis of the projection level of modifiers of different grammatical categories. this study provides an analysis of the noun phrase structure in persian, considering the projection levels of the post-modifiers. the study is within the framework of the extended standard theory (est) and, in particular, x-bar syntax. data an...
