Does social capital as resources of network members affect health information search? Analyzing data from the 2004 General Social Survey in the United States, this study measures two social capital indicators (average education of network members and proportion of network members with a high school degree or higher) using the name generator. Most results are consistent using those two indicator...

We present a butterfly-compressed representation of the Hadamard–Babich (HB) ansatz for Green’s function high-frequency Helmholtz equation in smooth inhomogeneous media. For computational domain discretized with discretization cells, proposed algorithm first solves and tabulates phase HB coefficients via eikonal transport equations observation points point sources located at Chebyshev nodes usi...

This paper deals with the behaviour of acoustic cavities in the mid-high frequency range. The method proposed here is based on an energy flow method named Simplified Energy Method (MES). MES method is quite efficient in the mid-high frequency range but the directivity of the boundary sources is not well estimated. We propose a hybrid method which couples MES and the Boundary Element Method (BEM...

background: stroke is a leading cause of preventable morbidity and mortality in the united states. numerous studies have shown that dietary carbohydrates play an important role in stroke incident. therefore, this study aimed to assess the association between dietary intake of carbohydrate and its types and stroke incidence among iranian adults. methods: a case‑control study was performed among ...

RF and microwave power amplifiers and transmitters are used in a wide variety of applications including wireless communication, jamming, imaging, radar, and RF heating. This article provides an introduction and historical background for the subject, and begins the technical discussion with material on signals, linearity, efficiency, and RF-power devices. At the end, there is a convenient summar...

We investigate the possible contribution from the emission of accretion flows around supermassive black holes in early type galaxies to current measurements of the Cosmic Microwave Background (CMB) at radio frequencies. We consider a range of luminosities suggested by targeted radio observations and accretion models and compute the residual contribution of these sources to the spectrum and bisp...
