A robust ionospheric model is indispensable for providing the atmospheric delay corrections global navigation satellite system (GNSS) and positioning forecasting space environment. The accuracy of models limited due to simplified structures. Complicated spatiotemporal variations in total electron content (TEC) biases between GNSS international reference ionosphere (IRI) suggest a strategy optim...

Since there had been no previous studies of alterations in insulin sensitivity, glucose-stimulated insulin secretion, beta cell function and glucose effectiveness during the development of non-diabetic hyperglycemia in Asian populations, we conducted a longitudinal study of such changes in 244 Japanese adults with normal glucose tolerance (median BMI 23.3 kg/m(2) and age 51 yrs). The median fol...

We compare measured profiles of upper layer shear and rates of kinetic energy dissipation with the predictions of a one-dimensional turbulence model proposed by Craig and Banner (1994). Their formulation contains an unknown parameter, the "roughness length" z0, which we determine by fitting computed and observed dissipation rates. The resulting model, without further adjustment, is then used to...

The data related to the distribution of other focal infections in central nervous system (CNS) infection patients is inconsistent in medical literature. Infectious Diseases International Research Initiative (ID-IRI) has been carrying on multicenter and multinational studies since 2008 and provided bulk of information on pneumococcal meningitis, brucellar meningitis, tuberculous meningitis, and ...

The Global Positioning System (GPS) makes it possible to study the dynamics of the ionosphere by supplementing ionospheric studies carried out using various techniques including ionosondes, incoherent scatter radars and low earth orbit satellites. Total electron content derived from GPS data (GPS TEC) is a key parameter characterising the ionosphere. Its time evolution provides an indication of...

The China Seismo-Electromagnetic Satellite (CSES-01) provides in situ electron density (Ne) observations through Langmuir probes (LPs) the topside ionosphere since February 2018. CSES-01 is a sun-synchronous satellite probing around two fixed local times (LTs), 14 LT daytime sector and 02 night-time sector, at an altitude of about 500 km. Previous studies evidenced that seems to underestimate N...

Epidemiological studies have demonstrated that offspring born to mothers preeclampsia (PE) are at increased risk for developing cardiovascular diseases after birth, but the underlying mechanism is unknown. Angiotensin II receptor type 1 autoantibody (AT1-AA), an agonist acting via activation of the AT1 receptor, is believed to be involved in the pathogenesis of both PE and fetal growth restrict...
