Hybrid storage systems that consist of flash-based solid state drives (SSDs) and traditional disks are now widely used. In hybrid storage systems, there exists a two-level cache hierarchy that regard dynamic random access memory (DRAM) as the first level cache and SSD as the second level cache for disk storage. However, this two-level cache hierarchy typically uses independent cache replacement...

Pax6 is required for one of two distinct neurogenic lineages in the cerebral cortex38 Pax6 is a potent neurogenic gene and regulates bHLH transcription factors .. Summary The cells of the mammalian central nervous system (CNS) arise from multipotential precursor cells. The mechanisms that drive precursor cells toward a distinct cell fate are not well understood. Since transcription factors are ...

Given a system of n interacting finite state machines (FSM’s) and a state configuration, the reachability problem is to examine whether this configuration is reachable within the system. We investigate the complexity of this decision problem and three of its derivatives, namely l) verifying system determinism, 2) testing for the existence of unspecified inputs to any FSM within the system, and ...

As a generalization of Dempster-Shafer theory, the theory of D numbers is a new theoretical framework for uncertainty reasoning. Measuring the uncertainty of knowledge or information represented by D numbers is an unsolved issue in that theory. In this paper, inspired by distance based uncertainty measures for Dempster-Shafer theory, a total uncertainty measure for a D number is proposed based ...

In this study, for the first time in Iran, the karyotype of bigmouth Lotak, Cyprinion macrostomum Heckel, 1843, was investigated through examining metaphase chromosomes of seven fish with mean weight 30±5g caught by electrofishing from Godarkhosh River in Ilam Province. To stimulate cell divisions, fish were injected intraperitoneally two times by phytohemagglutinin (PHA). The cell divisions we...

Cell division orientation is crucial to control segregation of polarized fate determinants in the daughter cells to produce symmetric or asymmetric fate outcomes. Most studies in vertebrates have focused on the role of mitotic spindle orientation in proliferative asymmetric divisions and it remains unclear whether altering spindle orientation is required for the production of asymmetric fates i...

BACKGROUND AND OBJECTIVE The treatment of hepatocellular carcinoma (HCC) involves multidisciplinary clinical divisions and patients may be admitted to clinical divisions of different disciplinary nature. Few studies have assessed the potential effect of hospital admissions into different divisions on patient treatment options and survival. This study aimed to analyze this potential effect. ME...
