Harmonizing results of ataxia rating scales: mFARS, SARA, and ICARS

open access: yesAnnals of Clinical and Translational Neurology, Volume 9, Issue 12, Page 2041-2046, December 2022., 2022
Abstract The ever‐increasing body of ataxia research provides opportunities for large‐scale meta‐analyses, systematic reviews, and data aggregation. Because multiple standardized scales are used to quantify ataxia severity, harmonization of these measures is necessary for quantitative data pooling. We applied the modified Friedreich Ataxia Rating Scale

Tomography by Noise [PDF]

open access: yesPhysical Review Letters, 2014
We present an efficient and robust method for the reconstruction of photon number distributions by using solely thermal noise as a probe. The method uses a minimal number of pre-calibrated quantum devices, only one on/off single-photon detector is sufficient.

Optical full Hadamard matrix multiplexing and noise effects [PDF]

open access: yes, 2009
Hadamard multiplexing provides a considerable SNR boost over additive random noise but Poisson noise such as photon noise reduces the boost. We develop the theory for full H-matrix Hadamard transform imaging under additive and Poisson noise effects.

Numerical simulation of temperature variation in water layer induced by thermal jet in weak stratified environment

open access: yesAIP Advances, 2022
In order to explore the rising and diffusing path of an underwater thermal jet and the temperature variation of each water layer in the typical ocean thermohaline stratified environment, a three-dimensional mass-heat transport model of the thermal jet in

Metallic Ti3C2Tx MXene Gas Sensors with Ultrahigh Signal-to-Noise Ratio.

open access: yesACS Nano, 2018
Achieving high sensitivity in solid-state gas sensors can allow the precise detection of chemical agents. In particular, detection of volatile organic compounds (VOCs) at the parts per billion (ppb) level is critical for the early diagnosis of diseases ...

Chaos and noise [PDF]

open access: yesChaos: An Interdisciplinary Journal of Nonlinear Science, 2013
Simple dynamical systems—with a small number of degrees of freedom—can behave in a complex manner due to the presence of chaos. Such systems are most often (idealized) limiting cases of more realistic situations. Isolating a small number of dynamical degrees of freedom in a realistically coupled system generically yields reduced equations with terms ...

EMD-based filtering (EMDF) of low-frequency noise for speech enhancement [PDF]

open access: yes, 2012
An Empirical Mode Decomposition based filtering (EMDF) approach is presented as a post-processing stage for speech enhancement. This method is particularly effective in low frequency noise environments.

On the definition of noise

open access: yesHumanities and Social Sciences Communications, 2022
AbstractUrbanization has exposed people to extreme sound levels. Although researchers have investigated the ability of people to listen, analyze, and distinguish sound, the concept of noise has not been clearly articulated from a human perspective. The lack of knowledge on how people perceive noise limits our capacity to control it in a targeted manner.
