Progress in Earth and Planetary Science, 2021 We present results of an effort to evaluate the ability of an analytic model to describe the behavior of the equatorial zonal plasma drifts given inputs provided by readily available climatological models of thermospheric and ionospheric parameters. In a

Estimating the global abundance of ground level presence of particulate matter (PM2.5)
Geospatial Health, 2014 With the increasing awareness of the health impacts of particulate matter, there is a growing need to comprehend the spatial and temporal variations of the global abundance of ground level airborne particulate matter with a diameter of 2.5 microns or ...

Geodesics on metrics of Eguchi–Hanson type
European Physical Journal C: Particles and Fields, 2023 Geodesic equations are solved when at least two of $$\theta $$ θ , $$\phi $$ ϕ and $$\psi $$ ψ are constant, or r is constant, on scalar flat metrics of Eguchi–Hanson type.

Selfdual backgrounds in N=2 five-dimensional Chern-Simons Supergravity [PDF]
, 2000 We consider five-dimensional S(2,2|N) Chern-Simons supergravity on M_4 * R . By fine-tuning the Kaluza-Klein reduction to make the 4d cosmological constant equal zero, it is shown that selfdual curvatures on M_4 provide exact solutions to the equations ...

Twistor spinors with zero on Lorentzian 5-space [PDF]
, 2006 We present in this paper a $C^1$-metric on an open neighbourhood of the origin in $\RR^{5}$. The metric is of Lorentzian signature $(1,4)$ and admits a solution to the twistor equation for spinors with a unique isolated zero at the origin.

Immunoprofiling of leukemic stem cells CD34+/CD38−/CD123+ delineate FLT3/ITD-positive clones
Journal of Hematology & Oncology, 2016 Background Acute myeloid leukemia (AML) is a heterogeneous clonal disorder presenting with accumulation of proliferating undifferentiated blasts. Xenograft transplantation studies have demonstrated a rare population of leukemia-initiating cells called ...

Gravitational instantons with conformally coupled scalar fields
Journal of High Energy Physics, 2022 We present novel regular Euclidean solutions to General Relativity in presence of Maxwell and conformally coupled scalar fields. In particular, we consider metrics of the Eguchi-Hanson and Taub-NUT families to solve the field equations analytically.
