The Wide Field Imager (WFI) is one of two focal plane instruments the Advanced Telescope for High-Energy Astrophysics (Athena), ESA’s next large x-ray observatory, planned launch in early 2030s. current baseline halo orbit around L2, and second Lagrangian point Sun-Earth system L1 under consideration. For both potential orbits, radiation environment, solar cosmic protons, electrons, He-ions wil...

Although therapy with mineralocorticoid receptor antagonists (MRAs) is recommended for patients with chronic heart failure (HF) with reduced ejection fraction and in post-infarction HF, it has not been studied well in acute HF (AHF) despite being commonly used in this setting. At high doses, MRA therapy in AHF may relieve congestion through its natriuretic properties and mitigate the effects of...

Escherichia coli is routinely used for the production of recombinant proteins both for research purposes and for commercial applications. Despite the extensive amount of knowledge gathered about the synthesis and accumulation of heterologous proteins and the well established principals affecting the production of secondary metabolites, little attention has been paid to the effects of medium com...

Abstrac: In this paper, we investigate the influence of process parameters like HALO and Source/Drain (S/D) Implantation on threshold voltage in 45nm PMOS device. The settings of process parameters were determined by using Taguchi experimental design method. The level of importance of the process parameters on threshold voltage was determined by using analysis of variance (ANOVA). The virtual f...

The ATHENA and ATRAP groups at CERN recently reported the production of weakly bound antihydrogen atoms in a non-neutral positron-antiproton plasma. This Letter derives an equation of motion for weakly bound atoms in the electric and magnetic fields of the plasma and trap. The atoms are polarized by the electric field and can be trapped radially in the edge region of the plasma where the electr...

In these proceedings we present recent efforts to understand the energetics of magnetohydrodynamic (MHD) turbulence driven by the magneto-rotational instability (MRI). These studies are carried out in the local (shearing box) approximation using the Athena simulation code. Athena is a higher order Godunov algorithm based on the piecewise parabolic method (PPM), the corner transport upwind (CTU)...

Project management tools are mandatory to properly manage software projects. The teaching of the usage of these tools is carried out in higher education computer courses and, usually generic tools are adopted, such as MS-Project. However, their lack of educational features has motivated the development of several educational project management tools. This study aims at the analysis of such exis...
