Translucent windows: How uncertainty in competitive interactions impacts detection of community pattern
Rafael D'Andrea, Annette Ostling, James P O'Dwyer
Trait variation and similarity among coexisting species can provide a window into the mechanisms that maintain their coexistence. Recent theoretical explorations suggest that compe…
Widespread bursts of diversification in microbial phylogenies
Alice Doucet-Beaupré, James P. O'Dwyer
Until recently, much of the microbial world was hidden from view. A global research effort has changed this, unveiling and quantifying microbial diversity across enormous range of…
Non-Perturbative Tachyon Potential from the Wilsonian Renormalization Group
James P. O'Dwyer
The derivative expansion of the Wilsonian renormalization group generates additional terms in the effective beta-functions not present in the perturbative approach. Applied to the…
One Mass-Radius relation for Planets, White Dwarfs and Neutron Stars
D. Lynden-Bell, J. P. O'Dwyer
We produce the simple formula for the radius R of a cold body of mass M, (4 pi rho/3)^{1/3} R = I.M^{1/3} / [1+ (M/Mp)^{2/3}], where I is one for white dwarfs with non-relativistic…
