We extend the general solution to the Cauchy problem for the relativistic closed string (Phys. Lett. B404 (1997) 57-65) to the case of open strings attached to Dp-branes, including the cases where the initial data has a knotlike topology. We use this extended solution to derive intrinsic dynamical properties of open and closed relativistic strings attached to Dp-branes. We also study the singul...

The main purpose of the study reported in this paper was to examine the interrelationships between L2 risk-taking, English learning motivation, L2 speaking anxiety, linguistic confidence, and low-proficiency English as a foreign language (EFL) learners’ speaking complexity, accuracy, and fluency (CAF). A secondary purpose was to test whether task repetition can influence the level of the mentio...

Given an i.i.d. sequence of n letters from a finite alphabet, we consider the length of the longest run of any letter. In the equiprobable case, results for this run turn out to be closely related to the well-known results for the longest run of a given letter. For coin-tossing, tail probabilities are compared for both kinds of runs via Poisson approximation.

abstractthis study investigates ‘repetition’ in the english translation of the arabic novel, adrift on the nile (1993). it aims to explore the communicative functions of ‘repetition’ and to see if these functions have been maintained or lost in the process of translating the novel. in addition, it seeks to find the translation strategies used in rendering ‘repetition’. to achieve this aim, a de...

Various studies focusing on the effectiveness of teacher-parents relationship emphasize the positive effects of parents’ involvement in education. This study aimed to examine the effects of teacher-parents relationship on Iranians EFL learners’ language proficiency at elementary level. It also aimed to find how this relationship may influence  parents’ motivation and attitude with regard to the...
