Recent analysis by the IPCC suggests that, across an array of scenarios, both GHG emissions reductions and various degrees carbon removal will be required to achieve climate stabilization at a level that avoids most dangerous changes in future. Among large number options realm natural solutions, atmospheric dioxide (CDR) via enhanced silicate weathering (EW) global working lands could, theory, ...

Electric wheelchairs (EW) experience various terrain surfaces and slopes as well as occupants with diverse weights. This, in turn, imparts a substantial amount of perturbation to the EW dynamics. In this paper, we make use of a two-degree-of-freedom control architecture called disturbance observer (DOB) which reduces sensitivity to model uncertainties, while enhancing rejection of disturbances ...

We review the motivation for, lattice results on, and some implications of, external magnetic fields present at the time of the cosmological electroweak phase transition.

The Higgs-boson production in association with a W-boson pair at e+e− linear colliders is one of the important processes in probing the coupling between Higgsboson and vector gauge bosons and discovering the signature of new physics. We describe the impact of the complete electroweak(EW) radiative corrections of O(αew) to this process in the standard model(SM) at the International Linear Collid...

A reversal of the normal two-fluid competitive (water vs oil) electrowetting (nEW) on dielectric has been achieved by plasma irradiation of the normally hydrophobic fluoropolymer followed by thermal annealing. This process first renders the surface hydrophilic and then returns it to its normal hydrophobic properties as measured by water droplet contact and rolling angles. In the plasma-irradiat...

Na+ channel blockers flecainide and quinidine can increase propensity to ventricular tachyarrhythmia, whereas lidocaine and mexiletine are recognized as safe antiarrhythmics. Clinically, ventricular fibrillation is often precipitated by transient tachycardia that reduces action potential duration, suggesting that a critical shortening of the excitation wavelength (EW) may contribute to the arrh...
