Reduced Order Model for a Convective Rotating Annulus with Localized Forcing

Announce Type: new Abstract: A low-order Galerkin model is developed for a rotating fluid annulus driven by localized heating at the outer bottom periphery, with uniform cooling at the inner cylindrical wall. The model retains the full cylindrical geometry and employs Bessel-function radial eigenfunctions satisfying physically correct Dirichlet-Neumann boundary conditions. A dual-series least-squares procedure determines the conductive base state under the mixed thermal boundary condition.

Multiple critical Froude numbers for the centrifugal effects on heat transport in rotating Rayleigh-B\'{e}nard convection

arXiv:2606.06116v1 Announce Type: new Abstract: The influence of centrifugal effects in rotating Rayleigh-Benard convection is investigated using direct numerical simulations. We find that the Nusselt number decreases beyond a critical Froude number, Fr_c*.

This drug delayed rheumatoid arthritis for years after treatment ended

This drug delayed rheumatoid arthritis for years after treatment ended - Date: - June 1, 2026 - Source: - King's College London - Summary: - A promising new study suggests rheumatoid arthritis may not be as inevitable as once thought for people at high risk. Researchers found that just one year of treatment with the immune-targeting drug abatacept delayed the onset of rheumatoid arthritis by up to four years, with benefits lasting long after treatment ended. - Share: People at high risk of...
