Backreaction on the luminosity-redshift relation from gauge invariant light-cone averaging

open access: yes, 2012
Using a recently proposed gauge invariant formulation of light-cone averaging, together with adapted "geodesic light-cone" coordinates, we show how an "induced backreaction" effect emerges, in general, from correlated fluctuations in the luminosity ...

Anomalous Conical Di-jet Correlations in pQCD vs AdS/CFT

open access: yes, 2009
We propose an identified heavy quark jet observable to discriminate between weakly coupled pQCD and strongly coupled AdS/CFT models of quark gluon plasma dynamics in ultra-relativistic nuclear collisions at RHIC and LHC energies.

Elevated levels of the stress hormone, corticosterone, cause ‘pessimistic’ judgment bias in broiler chickens

open access: yesScientific Reports, 2017
Pessimistic judgment biases, whereby humans or non-human animals interpret ambiguous information negatively, are hypothesised to be one of the suite of adaptive changes that comprise the vertebrate stress response.

Development of a Synthetic 3D Platform for Compartmentalized Kidney In Vitro Disease Modeling

open access: yesAdvanced Healthcare Materials, EarlyView.
A fully synthetic, compartmentalized 3D kidney disease model is introduced. The kidney model combines a PEG‐based hydrogel matrix with anisotropic, enzymatically degradable rod‐shaped microgels to spatially arrange a triple co‐culture of key renal epithelial, endothelial, and fibroblast cells.
