Finding a suitable estimation of stability domain around stable equilibrium points is an important issue in the study of nonlinear dynamical systems. This paper intends to apply a set of analytical-numerical methods to estimate the region of attraction for autonomous nonlinear systems. In mechanical and structural engineering, autonomous systems could be found in large deformation problems or c...

One of the oldest and most pleasant and efficient kinds of poetry, which have attracted the attention of scholars and lovers of poetry since the beginning of the Persian poetry until now, is elegy. Khaghani Shervani is one of the poets who wrote after this genre and composed many memorable and beautiful elegies. The poet, who like many other people experienced happy and sad events and occasions...

the aim of this paper is to generalize the‎‎notion of pseudo-almost valuation domains to arbitrary‎ ‎commutative rings‎. ‎it is shown that the classes of chained rings‎ ‎and pseudo-valuation rings are properly contained in the class of‎ ‎pseudo-almost valuation rings; also the class of pseudo-almost‎ ‎valuation rings is properly contained in the class of quasi-local‎ ‎rings with linearly ordere...

background: dengue is a global arboviral threat to humans; causing 390 million infections per year. the availability of safe and effective tetravalent dengue vaccine is a global requirement to prevent epidemics, morbidity, and mortality associated with it. methods: five experimental groups (6 mice per group) each of 5-week-old balb/c mice were immunized with vaccine and placebo (empty plasmid) ...

7 Atrial fibrillation (AF) is the most common cardiac arrhythmia whose me8 chanisms are thought to be mainly due to the self perpetuation of spiral waves 9 (SW). To date, available treatment strategies (antiarrhythmic drugs, radiofre10 quency ablation of the substrate, electrical cardioversion) to restore and to 11 maintain a normal sinus rhythm have limitations and are associated with AF 12 re...
