[HTML][HTML] Spatial dysregulation of T follicular helper cells impairs vaccine responses in aging

…, JL Lee, LMC Webb, WS Foster, RCJ McKenzie… - Nature …, 2023 - nature.com
The magnitude and quality of the germinal center (GC) response decline with age, resulting
in poor vaccine-induced immunity in older individuals. A functional GC requires the co-…

Superconductivity mediated by charge fluctuations in layered molecular crystals

J Merino, RH McKenzie - Physical Review Letters, 2001 - APS
We consider the competition between superconducting, charge ordered, and metallic phases

Phase diagram for a class of spin- Heisenberg models interpolating between the square-lattice, the triangular-lattice, and the linear-chain limits

Z Weihong, RH McKenzie, RRP Singh - Physical Review B, 1999 - APS
We study the spin-1 2 Heisenberg models on an anisotropic two-dimensional lattice which
interpolates between the square lattice at one end, a set of decoupled spin chains on the …

A first-principles density-functional calculation of the electronic and vibrational structure of the key melanin monomers
