Modeling the Plasma Frequency for F2-Region Using Modified Chapman Function and NeQuick2 Model over Different Geographical Locations and Months [PDF]
Engineering and Technology Journal, 2019 This study aims to modeling the plasma frequency profile of the F2 region as a function of geographical location and month of the y ear. The most important model and function used are Chapman function and NeQuick 2 model which have been defined both by ...

Dual-Energy Computed Tomography For Differentiation Between Osteoblastic Metastases and Bone Islands
Frontiers in Oncology, 2022 ObjectiveThe objective of our study was to evaluate the utility of Rho/Z on dual-energy computed tomography (DECT) for the differentiation of osteoblastic metastases (OBMs) from bone islands (BIs).MethodsDECT images of 110 patients with malignancies were

Spatial structure of an incompressible Quantum Hall strip
, 1999 The incompressible Quantum Hall strip is sensitive to charging of localized states in the cyclotron gap. We study the effect of localized states by a density functional approach and find electron density and the strip width as a function of the density ...

THE MOSDEF SURVEY: ELECTRON DENSITY AND IONIZATION PARAMETER AT z ∼ 2.3 [PDF]
, 2015 Using observations from the MOSFIRE Deep Evolution Field survey, we investigate the physical conditions of star-forming regions in z ∼ 2.3 galaxies, specifically the electron density and ionization state. From measurements of the [O ii]λλ3726,3729 and [S

FEBS Letters, EarlyView.Bifidobacterium bifidum establishes symbiosis with infants by metabolizing lacto‐N‐biose I (LNB) from human milk oligosaccharides (HMOs). The extracellular multidomain enzyme LnbB drives this process, releasing LNB via its catalytic glycoside hydrolase family 20 (GH20) lacto‐N‐biosidase domain.
