Fixing the stimulus-as-fixed-effect fallacy in task fMRI
Wellcome Open Research, 2016 Abstract Most fMRI experiments record the brain’s responses to samples of stimulus materials (e.g., faces or words). Yet the statistical modeling approaches used in fMRI research universally fail to model stimulus variability in a manner that affords population generalization--meaning that researchers’ conclusions ...

Effective actions with fixed points [PDF]
Physical Review D, 1994 The specific form of the constant term in the asymptotic expansion of the heat kernel on an axially symmetric space with a codimension-two fixed-point set of conical singularities is used to determine the conformal change of the effective action in four dimensions. Another derivation of the relevant coefficient is presented.
