Delayed renewal process and delayed renewal reward process are introduced in the framework of uncertainty theory and their uncertainty distributions are provided. Furthermore, delayed renewal theorem on the limit value of the expected renewal rate of the process and delayed renewal reward theorem on the limit value of the long-run expected reward per unit time are presented. At last, some examp...

The wireless sensor network (WSN) is typically comprised many tiny nodes equipped with processors, sender/receiver antenna and limited battery in which it is impossible or not economic to recharge. Meanwhile, network lifespan is one of the most critical issues because of limited and not renewal used battery in WSN. Several mechanisms have been proposed to prolong network lifespan such as LEACH,...

In this paper, we construct fuzzy renewal processes involving fuzzy random variables. We first extend the renewal processes to the fuzzy renewal processes where interarrival times, rewards, and stopping times are all fuzzy random variables. According to these fuzzy renewal processes, we then extend some theorems of renewal processes to those in fuzzy renewal processes. These are elementary rene...

This paper presents a provably secure and efficient key agreement protocol (SNKE) using private key authentication. The distinguishing features of protocol SNKE are: (a) ease of implementation in the 802.15.4 stack (it makes use of the cryptographic services provided by the media access layer); (b) availability of two operation modes (hash-chain and key-renewal modes) with forward secrecy achie...

The purpose of this paper is to inform the Commission of the results of the U.S. Nuclear Regulatory Commission (NRC) staff=s review of the Oyster Creek Nuclear Generating Station (OCNGS) license renewal application submitted by AmerGen Energy Company, LLC, (AmerGen); and to request that the Commission authorize the Director of the Office of Nuclear Reactor Regulation (NRR) to make the appropria...

Self-renewal and differentiation of neural stem cells is essential for embryonic neurogenesis, which is associated with cell autophagy. However, the mechanism by which autophagy regulates neurogenesis remains undefined. Here, we show that Eva1a/Tmem166, an autophagy-related gene, regulates neural stem cell self-renewal and differentiation. Eva1a depletion impaired the generation of newborn neur...
