Economics of education which investigates economic issues related to education - presents a framework which leads to better schedules and policy-making. On the other hand, the concept of competitiveness has drawn increasing attention of both scholars and governors in the past decade. The World Economic Forum (WEF) has published Global Competitiveness Index (GCI) in order to measure national com...

In the past few decades, studies of exciton emissions coupled with metal nanoparticles have mainly focused on enhancing radiation and reducing lifetime by near-field coupling interactions between excitons nanoparticles. Only in recent years has plasmon-field-induced to extend (inhibition emission) been reported. Experimentally, for observing a long-lifetime state it needs satisfy condition <...

A leading cause of antibiotic-resistant hospital infection (1), Enterococcus faecalis, decorates its surface with proteins that contribute to its ability to colonize and survive. Several proteins, including Esp (2), aggregation substance (3), a collagen adhesin (4), and a pilin (5), correlate with a particular disease or exacerbate the course of infection in amodel system. In PNAS, Kandaswamy e...

ZnGeP<sub>2</sub> crystals are the frequency conversion materials with excellent comprehensive performances in a range of 3–5 μm. However, overlap absorption band and pump wavelength optical parametric oscillator at 8–12 μm limits application performance makes it impossible to achieve far-infrared laser output. In this work, formation energy migration mechanism six kinds defects cry...

The study of the interaction between highly charged ions and solid surfaces not only has great significance for basic scientific research such as atomic physics, astrophysics, high energy density physics but also promising application prospects in biomedicine, nanotechnology, surface analysis, microelectronics. In this paper, intermediate Rydberg states formed during <inline-formula><t...

Melting of the dielectric phase change material inside a closed square enclosure is numerically investigated. The fully coupled equations including Navier-Stokes equations, Poisson's equation, charge conservation equation and energy are solved using lattice Boltzmann method (LBM). Strong injection from high temperature vertical electrode considered basic characteristics fluid flow, transport he...

We study the creation of electron-positron pairs in vacuum induced by multi-photon transition process with combined oscillating fields. According to computational quantum field theory and split operator technique, we numerically solve spatiotemporally dependent Dirac equation. The effects frequencies on yields energy distributions are investigated.First, show that even for subcritical fields, g...

Crime on the railways in Britain is an increasing concern for train operating companies, the British Transport Police (BTP), passengers, and local residents. Significantly, rail users consistently perceive their risks from crime to be considerably higher than official crime statistics indicate, having a negative affect on levels of patronage. This article presents an exploratory study of passen...
