BACKGROUND A hub-and-spoke telestroke network is an effective way to extend quality emergency stroke care to remote hospitals and improve patient outcomes. OBJECTIVES To evaluate the cost utility of a telestroke network in the management of acute ischemic stroke from the societal perspective. STUDY DESIGN AND METHODS A lifetime Markov model was developed to compare the incremental costs and...

We have carried out saturation spectroscopy of cyclotron resonance in a semiconducting InAs/Al Ga Sb single quantum well using the UCSB free electron laser and have extracted an effective Landau level lifetime using an n-level rate equation model. The effective lifetime shows strong oscillations ('an order of magnitude) with frequency. Minima are shifted to higher frequencies than those given b...

In this paper a new four-parameter lifetime distribution named “the Exponentiated gompertz-poisson (E-GP) distribution” has been suggested that it has a decreasing, increasing, bathtub-shaped and inverse bathtub-shape for modeling lifetime data. The Exponentiated gompertz-poisson has applications in economics, actuarial modelling,reliability modeling, lifetime and queuing problems and biologica...

Sensor-deployment-based lifetime optimization is one of the most effective methods used to prolong the lifetime of Wireless Sensor Network (WSN) by reducing the distance-sensitive energy consumption. In this paper, data retransmission, a major consumption factor that is usually neglected in the previous work, is considered. For a homogeneous WSN, monitoring a circular target area with a centere...

In this paper, we present techniques for mitigating the Negative Bias Temperature Instability (NBTI) effect on extensible processors. Firstly, the effect of NBTI on the extended instruction set architecture and the arithmetic logic unit of extensible processors is studied. The study includes modeling the circuit delay increase due to the NBTI and analyzing its impact on the processor lifetime. ...

Actomyosin-based cortical flow is a fundamental engine for cellular morphogenesis. Cortical flows are generated by cross-linked networks of actin filaments and myosin motors, in which active stress produced by motor activity is opposed by passive resistance to network deformation. Continuous flow requires local remodeling through crosslink unbinding and and/or filament disassembly. But how loca...

LEACH is the most popular clastering algorithm in Wireless Sensor Networks (WSNs). However, it has two main drawbacks, including random selection of cluster heads, and direct communication of cluster heads with the sink. This paper aims to introduce a new centralized cluster-based routing protocol named LEACH-AEC (LEACH with Adaptive Energy Consumption), which guarantees to generate balanced cl...
