We develop nonlinear renewal theorems for a perturbed random walk without assuming stochastic boundedness of centered perturbation terms. A second order expansion of the expected stopping time is obtained via the uniform integrability of the difference between certain linear and nonlinear stopping rules. An intermediate renewal theorem is obtained which provides expansions between the nonlinear...

chronic myeloid leukemia (cml) is a myeloproliferative disease of the hematopoietic stem cells, characterized by the presence of the philadelphia (ph) chromosome. although imatinib inhibits the bcr-abl kinase activity, clinical experiences confirm that imatinib may not target cml stem cells in vivo. the identification of signaling pathways responsible for the self-renewal properties of leukemic...

Rapid urbanization has made the inner city change quickly with the urban sprawl of the whole city. In China, a mass of urban renewal projects have been carried out for meeting the new need of people’s life. However, the traditional means of total renewal has destroyed the urban heritage seriously, which especially led to the diminishing of historical district space. It is urgent to protect and ...

This paper describes a new approach to optimisation of railway track maintenance and renewal works via genetic algorithms. Decision support systems and genetic algorithms are used in this study to optimise railway track maintenance and renewal activities. The results obtained in the scope of this study show that planned maintenance and renewal management systems can be developed and successfull...

The concept of the renewal property is extended to processes indexed by a multidimensional time parameter. The definition given includes not only partial sum processes, but also Poisson processes and many other point processes whose jump points are not totally ordered. A new version of the waiting time paradox is proven for multidimensional Poisson processes, and is shown to imply the renewal p...

We define an inverse subordinator as the passage times of a subordinator to increasing levels. It has previously been noted that such processes have many similarities to renewal processes. Here we present an expression for the joint moments of the increments of an inverse subordinator. This is an analogue of a result for renewal processes. The main tool is a theorem on processes which are both ...

Community public space is an important place for daily communication between residents. In the context of current historical change “urban double repairs”, community renewal has raised new heights, and shifted from surface physical transformation layer to protection, inheritance environmental quality community. This article summarizes concept principles micro-renewal, analyzes related influenci...
