One probe for systematic effects in gravitational lensing surveys is the presence of so-called B-modes cosmic shear two-point correlation functions \xi_\pm(\vt), since expected to produce only E-mode shear. Furthermore, there exist ambiguous modes which can not uniquely be assigned either E- or B-mode We derive explicit equations pure-mode \xi_\pm^E/B(\vt) and their components \xi_\pm^amb(\vt),...

In this paper, nickel oxide (NiO) nanoparticles have been prepared by solid state thermal decomposition of an acyclic nickel(II) complex (1,2-bis(2-formyl-3-methoxyphenyl)propane)nickel(II) chloride, [NiL]Cl2, in an electrical furnace at optimal temperature, 450 ºC for 3.5 h. The nickel(II) complex is obtained via solid state synthesis using nickel(II) chloride and tetradentate O4 acyclic ligan...

A new physical mechanism or mode of plastic deformation in nanocrystalline metals and ceramics is suggested and theoretically described. The mode represents the cooperative grain boundary (GB) sliding and stress-driven GB migration process. It is theoretically revealed that the new deformation mode is more energetically favorable than "pure" GB sliding and enhances the ductility of nanocrystall...
