seizure activity has been proposed to result in the generation of reactive oxygen species (ros), which then contribute to seizure-induced neuronal damage and eventually cell death. although the mechanisms of seizure-induced ros generation are unclear, mitochondria and cellular calcium overload have been proposed to have a crucial role. we aim to determine the sources of seizure-induced ros and ...
In this paper, we study the phonon and thermal properties of a nanocrystal by using transfer matrix method in the harmonic approximation. The considered system is a mass-spring nanocrystal with a square cross section. At first, for the ideal case, we obtain the phonon spectrum with free boundary conditions. Then we calculate some phonon transport properties of this system, namely, the phonon de...
Group-based models arise in algebraic statistics while studying evolution processes. They are represented by embedded toric algebraic varieties. Both from the theoretical and applied point of view one is interested in determining the ideals defining the varieties. Conjectural bounds on the degree in which these ideals are generated were given by Sturmfels and Sullivant [SS05, Conjectures 29, 30...
This paper introduces two virtual Decision Making Units (DMUs) called ideal point and anti-ideal point, Then calculates distances of each DMU to the ideal and anti-ideal point. The two distinctive distances are combined to form a comprehensive index called the relative closeness (RC) just like the TOPSIS approach. The RC index is used as an overall ranking for all the DMUs. Then, this method co...
فرض کنیم a یک حلقه ی یکدار کاهش یافته (فاقد عنصر پوچ توان غیر بدیهی)باشد. خانواده تمام ایدآلهای اول سره از a را با spec(a)و خانواده تمام ایدآلهای اول مینیمال درa را باmin(a) نمایش می دهیم. مطالعات خوبی در مورد توپولوژی هسته غلافی (hull-kernel topology) یا همان توپولوژی زاریسکی،روی min(a)انجام شده است.به عنوان مثال این توپولوژی دارای پایه ای از زیرمجموعه های بستباز است. در این مقاله بر روی min...
