Ultra-high-field (UHF) MRI is ideally suited for structural and functional imaging of the brain. High-resolution structural MRI can be used to map the anatomical boundaries between functional domains of the brain by identifying changes related to the...

Observing fermionic statistics with photons in arbitrary processes (2013)
Journal Article

In contrast to classical physics, quantum mechanics divides particles into two classes-bosons and fermions-whose exchange statistics dictate the dynamics of systems at a fundamental level. In two dimensions quasi-particles known as 'anyons' exhibit f... Read More about Observing fermionic statistics with photons in arbitrary processes.

A variety of independent observational studies have now reported a significant decline in the fraction of Lyman-break galaxies which exhibit Ly-a emission over the redshift interval z=6-7. In combination with the strong damping wing extending redward...

Effects of various food ingredients on gall bladder emptying. European Journal of Clinical Nutrition, 67(11), https://doi.org/10.1038/ejcn.2013.168

Background/objectives: The emptying of the gall bladder in response to feeding is pivotal for the digestion of fat, but the role of various food ingredients in contracting the gall bladder postprandially is not well understood. We hypothesized that d... Read More about Effects of various food ingredients on gall bladder emptying.

Mechanical stiffening of porphyrin nanorings through supramolecular columnar stacking (2013)
Journal Article
Svatek, S. A., Perdigão, L. M., Stannard, A., Wieland, M. B., Kondratuk, D. V., Anderson, H. L., O'Shea, J. N., & Beton, P. H. (2013). Mechanical stiffening of porphyrin nanorings through supramolecular columnar stacking. Nano Letters, 13(7), https://doi.org/10.1021/nl4017557

Solvent-induced aggregates of nanoring cyclic polymers may be transferred by electrospray deposition to a surface where they adsorb as threedimensional columnar stacks. The observed stack height varies from single rings to four stacked rings with a l... Read More about Mechanical stiffening of porphyrin nanorings through supramolecular columnar stacking.

The cosmology of the Fab-Four (2012)
Journal Article

We have recently proposed a novel self tuning mechanism to alleviate the famous cosmological constant problem, based on the general scalar tensor theory proposed by Horndeski. The self-tuning model ends up consisting of four geometric terms in the ac... Read More about The cosmology of the Fab-Four.

Nonlinear modal coupling in a high-stress doubly-clamped nanomechanical resonator (2012)

Journal Article

Calibration of the BOLD signal is potentially of great value in providing a closer measure of the underlying changes in brain function related to neuronal activity than the BOLD signal alone, but current approaches rely on an assumed relationship bet...
