W polarisation beyond helicity fractions in top quark decays [PDF]

open access: yes, 2010
We calculate the density matrix for the decay of a polarised top quark into a polarised W boson and a massive b quark, for the most general Wtb vertex arising from dimension-six gauge-invariant effective operators.

The scaling of seed‐dispersal specialization in interaction networks across levels of organization

open access: yesEcography, EarlyView.
Natural ecosystems are characterized by a specialization pattern where few species are common while many others are rare. In ecological networks involving biotic interactions, specialization operates as a continuum at individual, species, and community levels. Theory predicts that ecological and evolutionary factors can primarily explain specialization.

Warming‐Mediated Decreases in Nectar Quality Translate Into Lower Energy Reserves of the Monarch Butterfly (Danaus plexippus)

open access: yesGlobal Change Biology Communications, EarlyView.
Warming caused a significant decrease in monarch fat mass, likely due to an observed reduction in sucrose concentration caused by warming of the nectar. Since sucrose fuels fall migration and overwintering, our results suggest climate warming may reduce migration success and overwinter survival.

Indirect effects of Seeking Safety plus sertraline on alcohol use: The mediating role of reductions in posttraumatic stress disorder symptom severity

open access: yesJournal of Traumatic Stress, EarlyView.
Abstract Posttraumatic stress disorder (PTSD) symptoms and alcohol use frequently co‐occur and are mutually reinforcing. Few studies have examined how changes in PTSD severity influence subsequent changes in alcohol use, particularly in the context of comorbidity treatments. This secondary analysis utilized data from a clinical trial comparing 12 weeks
