Characterization of two co-regulated response regulators in Clostridioides difficile [PDF]

Journal of Bacteriology
As an obligate anaerobe, Clostridioides difficile grows exclusively in the host intestinal tract, necessitating mechanisms to sense and respond to the gut environment.

Novel Tunable Pseudoresistor-Based Chopper-Stabilized Capacitively Coupled Amplifier and Its Machine Learning-Based Application [PDF]

Micromachines
This work presents a high-common-mode-rejection-ratio (CMRR) and high-gain FinFET-based bio-potential amplifier with a novel CMRR reduction technique. In this paper, a feedback buffer is used alongside a capacitively coupled chopper-stabilized circuit to

Phase variation of Clostridioides difficile colony morphology occurs via modulation of cell division. [PDF]

PLoS Pathogens
Phase variation of C. difficile colony morphology occurs via modulation of transcription of cmrRST, which encodes a three-protein signal transduction system. Response regulators CmrR and CmrT promote rough colony development, cell elongation and chaining,

Wide-bandwidth CFOA with high CMRR performance [PDF]

AEU - International Journal of Electronics and Communications, 2014
Abstract In this paper the authors analyze the conventional current-feedback operational amplifier (CFOA) in terms of common-mode-rejection ratio (CMRR) performance, and having identified the mechanism primarily responsible for the CMRR, they propose two new architecture CFOAs.

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 ...

Lowering the thermal noise barrier in functional brain mapping with magnetic resonance imaging

Nature Communications, 2021
The signal-to-noise ratio is a key consideration when selecting a magnetic resonance imaging protocol. Thermal noise is major issue, especially in high resolution functional images.

Coal mine roof rating (CMRR), rock mass rating (RMR) and strata control: Carborough Downs Mine, Bowen Basin, Australia

International Journal of Mining Science and Technology, 2020
The rock mass rating (RMR) has been used across the geotechnical industry for half a century. In contrast, the coal mine roof rating (CMRR) was specifically introduced to underground coal mines two decades ago to link geological characterization with ...
