Signal to Noise Ratio as a Cross-Platform Metric for Intraoperative Fluorescence Imaging

Here we introduce the signal-to-noise ratio (SNR) to characterize the ultimate sensitivity of an imaging system, and optimize factors such as pixel size. Expand abstract.

Socially dominant, aggressive males are poor influencers of group-consensus in a social fish

Dominant males occupy more spatially distant positions, and had lower signal-to-noise ratio of informative behavior in the association task, while subordinate males are typically is close physical association with their group members, have high signal-to-noise behaviors in the association task, and...

Delta-Sigma Modulator based Compact Sensor Signal Acquisition Front-end System

The proposed delta-sigma modulator ($\Delta\Sigma$M) based signal acquisition architecture uses a differential difference amplifier (DDA) customized for dual purpose roles, namely as instrumentation amplifier and as integrator of $\Delta\Sigma$M. Expand abstract.

Sharp images from diffuse beams: factorisation of the discrete delta function

Such large arrays can be applied to ghost imaging, which has demonstrated potential to greatly improve signal-to-noise ratios and reduce the total dose required for tomographic imaging. Expand abstract.

External and Internal Signal-to-noise Ratios Alter Timing and Location of Cortical Activities During Speech-in-noise Perception

Through our within-subject analysis of source-localized electroencephalography, we demonstrated how acoustic signal-to-noise ratio (SNR) alters neural activities along the auditory-motor pathway, or dorsal stream, of speech perception. Expand abstract.

Full-waveform inversion imaging of the human brain

Laboratory ultrasound data, using ex-vivo human skulls, demonstrate that our computational experiments mimic the penetration and signal-to-noise ratios expected in clinical applications. Expand abstract.

High signal-to-noise ratio reconstruction of low bit-depth optical coherence tomography using deep learning

Reducing the bit-depth is an effective approach to lower the cost of optical coherence tomography (OCT) systems and increase the transmission efficiency in data acquisition and telemedicine. Expand abstract.

Probing a stationary non-Gaussian background of stochastic gravitational waves with pulsar timing arrays

We quantitatively show how monitoring a large number of pulsars can increase the signal-to-noise ratio associated with measurements of stationary graviton nG. Expand abstract.

Spatial resolution, noise and information in the computational-imaging era

An intrinsic duality of spatial resolution and signal-to-noise exists in almost all types of imaging, with the related uncertainty relationship determining a trade-off between the two quantities. Expand abstract.

Interferometric Closure Phase Uncertainties in the Low Signal-to-Noise Ratio Regime

The resulting approximations perform much better than the Normal distribution for a wide range of signal-to-noise ratios and, being fully analytic, allow for fast computations that enable them to be incorporated in statistical algorithms. Expand abstract.
