Coupled Resonator Optical Waveguides: Toward the Slowing and Storage of Light [PDF]
, 2005 The development of a simple, solid-state-based technology to slow the propagation of light could prove an important step in the realization of the high-bit-rate communication systems of the future.

Performance in Object-Choice Aesop's Fable Tasks Are Influenced by Object Biases in New Caledonian Crows but not in Human Children. [PDF]
PLoS ONE, 2016 The ability to reason about causality underlies key aspects of human cognition, but the extent to which non-humans understand causality is still largely unknown. The Aesop's Fable paradigm, where objects are inserted into water-filled tubes to obtain out-

Crows Rival Monkeys in Cognitive Capacity
Scientific Reports, 2017 The present study compares the ‘bandwidth of cognition’ between crows and primates. Working memory is the ability to maintain and manipulate information over short periods of time – a core component of cognition. The capacity of working memory is tightly

West Nile Virus and High Death Rate in American Crows
Emerging Infectious Diseases, 2004 We document effects of West Nile virus (WNV) on American Crows. More than two thirds of our crows died of WNV infection, peaking when the proportion of infected mosquitoes at roosts was greatest. WNV antibody prevalence in crows was low.

New Caledonian crows learn the functional properties of novel tool types.
PLoS ONE, 2011 New Caledonian crows were presented with Bird and Emery's (2009a) Aesop's fable paradigm, which requires stones to be dropped into a water-filled tube to bring floating food within reach.

Slow waves in locally resonant metamaterials line defect waveguides [PDF]
, 2016 In the past decades, many efforts have been devoted to the temporal manipulation of waves, especially focusing on slowing down their propagation. In electromagnetism, from microwave to optics, as well as in acoustics or for elastic waves, slow wave ...
