Extreme non-linear elasticity and transformation optics [PDF]

Optics Express, 2010
Transformation optics is a powerful concept for designing novel optical components such as high transmission waveguides and cloaking devices. The selection of specific transformations is a non-unique problem. Here we reveal that transformations which allow for all dielectric and broadband optical realizations correspond to minimizers of elastic energy ...

Dissecting Neuronal Activation on a Brain-Wide Scale With Immediate Early Genes

Frontiers in Neuroscience, 2020
Visualizing neuronal activation on a brain-wide scale yet with cellular resolution is a fundamental technical challenge for neuroscience. This would enable analyzing how different neuronal circuits are disrupted in pathology and how they could be rescued

Tracking the Effect of Therapy With Single-Trial Based Classification After Stroke

Frontiers in Systems Neuroscience, 2022
Stroke is a debilitating disease that leads, in the 50% of cases, to permanent motor or cognitive impairments. The effectiveness of therapies that promote recovery after stroke depends on indicators of the disease state that can measure the degree of ...

Quantification of Myocyte Disarray in Human Cardiac Tissue

Frontiers in Physiology, 2021
Proper three-dimensional (3D)-cardiomyocyte orientation is important for an effective tension production in cardiac muscle. Cardiac diseases can cause severe remodeling processes in the heart, such as cellular misalignment, that can affect both the ...

Bounds on the Probability of Success of Postselected Non-linear Sign Shifts Implemented with Linear Optics [PDF]

, 2003
The fundamental gates of linear optics quantum computation are realized by using single photons sources, linear optics and photon counters. Success of these gates is conditioned on the pattern of photons detected without using feedback.

Non-linear optics with two trapped atoms [PDF]

, 2007
We show theoretically that two atomic dipoles in a resonator constitute a non-linear medium, whose properties can be controlled through the relative position of the atoms inside the cavity and the detuning and intensity of the driving laser.
