Unsteady MHD Heat Transfer of a Casson–Williamson Ternary Hybrid Nanofluid Over a Biaxially Stretching/Shrinking Sheet With Cattaneo–Christov Heat Flux and Multi‐Mode Thermal Radiation

Engineering Reports, Volume 8, Issue 7, July 2026.
A numerical study of Casson–Williamson ternary hybrid nanofluid flow reveals that magnetic effects enhance transverse velocity while suppressing axial components, and increased thermal relaxation reduces heat transfer rates under multiple radiation models, highlighting improved control of thermal performance in advanced engineering and electronics ...

Technology Development Outsourcing: When to Join Forces With a Rival?

Journal of Operations Management, Volume 72, Issue 5, Page 676-688, July 2026.
ABSTRACT Knowing the challenges of collaborating with a competitor in developing new technologies, firms sometimes still choose a competitor instead of a noncompeting technology provider. To explore why, this study adopts an inter‐organizational trust view to explain the formation of a technology development outsourcing relationship.
