چکیده
Twenty years ago, modal and mixed specifications were proposed as abstract models of system behavior. In this paper, we explain the nature and utility of such specifications, relate them to other formalisms, showcase some of their established applications, and mention some existing tool support. We also present some recent complexity results for decision problems underlying such applications and list some remaining open problems.

It is shown that every almost linear bijection $h : Arightarrow B$ of a unital $C^*$-algebra $A$ onto a unital$C^*$-algebra $B$ is a $C^*$-algebra isomorphism when $h(3^n u y) = h(3^n u) h(y)$ for allunitaries $u in A$, all $y in A$, and all $nin mathbb Z$, andthat almost linear continuous bijection $h : A rightarrow B$ of aunital $C^*$-algebra $A$ of real rank zero onto a unital$C^*$-algebra...
متن کاملاثر ویتامین C بر التهاب القا شده توسط فرمالین در موش صحرایی
Background and Objective: Vitamin C (Vit.C) or ascorbic acid is an essential micronutrient which has neuroprotective effects and can decrease Cyclooxygenase-2 (COX-2) activity and then prostaglandins synthesis. Therefore, it is hypothesized that Vit. C is able to reduce the inflammatory edema. In order to verify this hypothesis, a model of inflammatory paw edema was induced by formalin in rats....

Background and Objective: Ischemia-reperfusion (I/R) injury repeatedly occurs in situations such as surgery, hemorrhage, burns, trauma, and infection. It has also been found that females were more resistant than males, indicating that female sex hormones have a protective function. The aim of this study was to determine the role of estrogen, progesterone, and their combination in protecting the...
