For non-uniform magnetic textures, we derive an intrinsic contribution to the non-adiabatic spin torque that may be the dominant contribution. It differs from...
17-4 precipitation hardenable (PH) stainless steel is a useful material when a combination of high strength and good corrosion resistance up to about 315 °C is...
Relaxation processes for imidazolium-based ionic liquids (ILs) were investigated by means of an incoherent quasiealstic neutron scattering technique. In order...
This paper concerns the design and development of a prototype system for performance modeling and optimization of manufacturing processes. The prototype system...
Integrating software developed by third-party organizations into a larger system raises concerns about the software's quality, origin, functionality, security...
The article focuses on the tier 3 security risks related to the operation and use of cloud-based information systems. To prevent and mitigate any threats...
