The emergence of cloud computing and big data has rapidly increased the deployment of small and mid-sized data centers. Enterprises and cloud providers require an agile network among these data centers to empower application reliability and flexible scalability. We present a software-defined inter data center network to enable on-demand scale out of data centers on a metro-scale optical network...

background : about 5% of the world population are carriers of the hepatitis b virus which is not the same in different areas of the world. iran, with a rate of 2-3%, is among the countries with average prevalence. the aim of this study was to determine the prevalence of hbsag and its associated factors in pregnant women who referred to urban health centers in isfahan province. methods : this wa...

Dr Hoffman and colleagues were frustrated and perplexed after a persistent epidemic of diffuse lamellar keratitis at the Oregon Eye Institute, Eugene, Oregon.The incidence of DLK during the epidemic ranged from 16% to 85% per surgical day, he told a session of the XXII Congress of the ESCRS. Previous outbreaks of DLK have been attributed by other investigators to everything from bacterial endot...

The paper studies L∞(IR )-norm approximations from a space spanned by a discrete set of translates of a basis function φ. Attention here is restricted to functions φ whose Fourier transform is smooth on IR\0, and has a singularity at the origin. Examples of such basis functions are the thin-plate splines and the multiquadrics, as well as other types of radial basis functions that are employed i...

Objectives: In this study, we aimed to determine the individual characteristics of clients who were referred to residential rehabilitation centers for drug use disorders and to determine their relapse-related factors. Methods: This cross-sectional study was conducted on 576 patients who were referred to nine residential treatment centers for drug use disorders, chosen by the cluster sampling m...

In the last thirty years, there has been a dramatic growth in the trading of options, which are contracts between two parties giving one party the right but not the obligation to partake in a financial transaction with the other party at or before a specified date in the future. The majority of options involve the right to buy or sell an underlying asset at a prescribed price, known as the stri...

Nursing leaders play a critical role in creating and enacting a vision for collaborative practice with advanced practice nurses (APNs). In this special issue, Nancy Carter and colleagues have identified many important influences and outcomes of successful nursing leadership in the context of promoting advanced practice nursing roles. The authors make a strong case for the importance of nursing ...

We study the conductivity of a three-dimensional disordered metal close to antiferromagnetic instability within the framework of the spin-fermion model using the diagrammatic technique. We calculate the interaction correction δσ(ω,T) to the conductivity, assuming that the latter is dominated by the disorder scattering, and the interaction is weak. Although the fermionic scattering rate shows cr...
