NOise reduction with DIstribution Corrected (NORDIC) PCA in dMRI with complex-valued parameter-free locally low-rank processing

NeuroImage, 2021
Diffusion-weighted magnetic resonance imaging (dMRI) has found great utility for a wide range of neuroscientific and clinical applications. However, high-resolution dMRI, which is required for improved delineation of fine brain structures and ...

Metabolomic Signatures and Machine Learning Models for Distinguishing Alzheimer's Disease and Dementia with Lewy Bodies [PDF]

Alzheimers Dement
Abstract Background Alzheimer's Disease (AD) and Dementia with Lewy Bodies (DLB) are difficult to distinguish clinically due to overlapping symptoms, resulting in delayed or incorrect diagnoses. This study uses metabolomic profiles from serum samples and machine learning models to identify key biomarkers that distinguish these conditions.

A CMRR enhancement circuit by employing auxiliary buffer of capacitively coupled instrumentation amplifier for neural signal recording

Electronics Letters, 2021
Here, a common‐mode rejection ratio (CMRR) enhancement circuit is proposed by employing an auxiliary buffer (AB) to the pseudo resistors of the capacitively coupled instrumentation amplifier (CCIA).

Investigation of factors influencing roof stability at a Western U.S. longwall coal mine

International Journal of Mining Science and Technology, 2019
The coal mine roof rating (CMRR) was developed to bridge the gap between geological variation in underground coal mines and engineering design. The CMRR accounts for the compressive strength of the immediate roof, the shear strength and intensity of any ...

Cortical layer-specific differences in stimulus selectivity revealed with high-field fMRI and single-vessel resolution optical imaging of the primary visual cortex

NeuroImage, 2022
The mammalian neocortex exhibits a stereotypical laminar organization, with feedforward inputs arriving primarily into layer 4, local computations shaping response selectivity in layers 2/3, and outputs to other brain areas emanating via layers 2/3, 5 ...

Multimode interference filter to solve degradation on coupler common-mode rejection [PDF]

, 1998
After quantifying degradation of a common mode rejection ratio (CMRR) 3dB-coupler due to excitation of TE01 mode, a novel compact circuit including multimode interference (MMI) coupler+bend+MMI+filter (CBF) is proposed.

Application of coal mine roof rating in Chinese coal mines

International Journal of Mining Science and Technology, 2018
The coal mine roof rating (CMRR) is a measure of roof quality or structure competency for bedded roof types typically of underground coal mines. The CMRR has been used widely in the US, South Africa, Canada and Australia.
