Adaptive interaction is a new approach to introduce adaptability into man made systems In this approach a system is decomposed into interconnected subsystems that we call devices and adaptation occurs in the interactions More precisely interac tion weights among these devices will be adapted in order to achieve the objective of minimizing a given cost function The adaptation algorithm developed...

it was thought previously that cardiac muscle gap junctions provide low-resistance connections between cells and permit the local-circuit current to flow. some evidences show that myocardial cells may not require low-resistance connections for successful propagation of the action potential (ap). it seems that some other types of mechanisms must be involved in ap propagation. in this article, we...

Makran subduction located at the northwest of the Indian Ocean nearby the southern coast of Iran and Pakistan. Makran subduction is the source of tsunamis that threaten southern coast of Iran. In this article, generation and propagation of 1945’s tsunami initiated by Makran subduction is simulated. For the three dimensional generation of the wave, advanced algorithm of Okada is adopted. The CFD...

objectives due to the lack of a standard tool for assessing patients’ capacity to consent to medical treatment in iran, the present study was carried out aiming to devise a persian version of a cross-cultural adaptation of the macarthur competence assessment tool. conclusions in the present study, we are able to focus on and prove the efficacy and benefits of this measurement tool. results the ...

Background and Objectives: Nowadays, the academic integrity suffers from invalid science. Researchers may use this bogus research and conduct their studies based on them, and present invalid findings. Identifying main factors which lead to junk science propagation can be important and this study aimed to determine factors which are affecting the propagation of junk science by using phenomenogra...

Background: Postpartum is a significant transition period for women and could be markedly stressful. Objectives: Postpartum stress is a well-established risk factor for poor parenting practices and inadequate mother-infant interaction. The present study aimed to assess adaptation to motherhood and its influential factors in the first year postpartum in Iranian women. Methods: This cross-secti...

corrosion of steel reinforcement is one of the most prevalent causes of reinforced concrete (rc) structures deterioration in chloride-contaminated environments. as a result, evaluating the impact of any possible corrosion-induced damages to reinforced concrete bridges strongly affects management decisions: such as inspection, maintenance and repair actions. the corrosion propagation phase is a ...

In this paper a space-averaged Navier–Stokes approach was deployed to simulate the wave propagation over coastal structures. The developed model is based on the smoothed particle hydrodynamic (SPH) method which is a pure Lagrangian approach and can handle large deformations of the free surface with high accuracy. In this study, the large eddy simulation (LES) turbulent model was coupled with th...
