A series of (Nd1?xSmx)Fe11Ti alloys with the ThMn12 crystal structure have been fabricated and characterized in order to promote a strong uniaxial anisotropy NdFe11Ti without need nitrogenation. The compounds show small changes lattice parameters cell volume, as well Curie temperature spontaneous magnetization. field, however, rapidly increases incorporation Sm overcomes effect nitrogenation, r...

First-principle supercell calculations are used to determine how elemental additions, especially Fe additions, modify the magnetiza-tion, exchange and anisotropy of-ordered ferromagnets. Calculations are performed using the VASP code and partially involve con-figurational averaging over site disorder. Three isostructural systems are investigated: Fe-Co-Pt, Mn-Al-Fe, and transition metal-doped F...

Completeness is a desirable property of test suites. Roughly, completeness guarantees that a nonequivalent implementation under test will always be identified. Several approaches proposed sufficient, and sometimes also necessary, conditions on the specification model and on the test suite in order to guarantee completeness. Usually, these approaches impose several restrictions on the specificat...

Sessile marine mussels must "dry" underwater surfaces before adhering to them. Synthetic adhesives have yet to overcome this fundamental challenge. Previous studies of bioinspired adhesion have largely been performed under applied compressive forces, but such studies are poor predictors of the ability of an adhesive to spontaneously penetrate surface hydration layers. In a force-free approach t...

Are neutrinos their own antiparticles? We explain why they very well might be. Then, after highlighting the fact that, to determine experimentally whether they are or not, one must overcome the smallness of neutrino masses, we discuss the one approach that nevertheless shows great promise. Finally, we turn to the consequences of neutrinos being their own antiparticles. These consequences includ...
