we introduce the notion ofstrongly $alpha$-reversible rings which is a strong version of$alpha$-reversible rings, and investigate its properties. we firstgive an example to show that strongly reversible rings need not bestrongly $alpha$-reversible. we next argue about the strong$alpha$-reversibility of some kinds of extensions. a number ofproperties of this version are established. it is shown ...

in this paper, we introduce a class of rings which is a generalization of reversible rings. let r be a ring with identity. a ring r is called central reversible if for any a,b ∈ r, ab=0 implies ba belongs to the center of r. since every reversible ring is central reversible, we study sufficient conditions for central reversible rings to be reversible. we prove that some results of reversible ri...

Reversible debuggers help programmers to quickly find the causes of misbehaviours in concurrent programs. These can be founded on well-studied theory causal-consistent reversibility, which allows one undo any action provided that its consequences are undone beforehand. Till now, reversibility never considered time, a key aspect real world applications. Here, we study interplay between and time ...

Platelet activation and adhesion to the site of vascular injury is a dynamic process comprising reversible and irreversible phases. Platelet adhesion typically occurs in a multi-step process similar to the selectin/integrin-mediated adhesion of neutrophils. This phenomenon is highly regulated and influenced by the cross-talk between platelets and injured endothelium. This cross-talk involves a ...

The notion of reversible computing is attracting interest because of its applications in diverse fields, in particular the study of programming abstractions for fault tolerant systems. Reversible CCS (RCCS), proposed by Danos and Krivine, enacts reversibility by means of memory stacks. Ulidowski and Phillips proposed a general method to reverse a process calculus given in a particular SOS forma...

The present paper studies a discrete-time storage process with discrete states. This model has the inflow which is defined as independent random variables with a common negative binomial distribution and has the certain outflow discipline. Reversibility and quasi-reversibility for the process are investigated and the reversible measure is given. And thus, under a certain condition, it is shown ...

cells are active components in their environment and constantly adjusting their performance to improve extracellular milieu changing. this approach is reflected their tends of maintaining intracellular homeostasis. when the cells encounter stress or pathologic stimuli, they can undergo a new manner (adaptation) and new steady state for achieving viability and function. if the external stress is...
