Microscopic origin of low frequency noise in MoS2 field-effect transistors
APL Materials, 2014 We report measurement of low frequency 1/f noise in molybdenum di-sulphide (MoS2) field-effect transistors in multiple device configurations including MoS2 on silicon dioxide as well as MoS2-hexagonal boron nitride (hBN) heterostructures.

, 1987 We describe the design, schematics, and performance of a very low noise FET cascode input amplifier. This amplifier has noise performance of less than 1.2 nV/Hz and 0.25 fA/Hz over the 500 Hz to 50 kHz frequency range.

Fluid Biomarkers of Disease Burden and Cognitive Dysfunction in Progressive Supranuclear Palsy
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Identifying objective biomarkers for progressive supranuclear palsy (PSP) is crucial to improving diagnosis and establishing clinical trial and treatment endpoints. This study evaluated fluid biomarkers in PSP versus controls and their associations with regional 18F‐PI‐2620 tau‐PET, clinical, and cognitive outcomes.

Influence of low frequency noise on cognitive performance tasks
Archives of Acoustics, 2004 To study the influence of low frequency noise (LFN) on cognitive performance tasks, 96 subjects, categorised in terms of sensitivity to LFN, worked with four standardised psychological tests during exposure to LFN or broadband noise ...

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.

Noise performance of frequency- and phase-locked CW magnetrons operated as current-controlled oscillators. [PDF]
, 2005 Low-power continuous wave ``cooker'' magnetrons driven from industrial-quality switch-mode power supplies have been frequency locked by driving them as current-controlled oscillators in a phase-lock loop (PLL).

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background Emerging evidence suggests that low‐frequency neural oscillations are dynamically regulated by consciousness levels, with the recovery of low cortical activity potentially serving as a neurophysiological substrate for conscious emergence. Targeted enhancement of these low‐frequency rhythms in patients with disorders of consciousness

The influences of low frequency noise on mental performance
Journal of Mazandaran University of Medical Sciences, 2008 Background and Purpose: Although the evolution of industrial systems toward digital technologies decreased the exposure to high levels of noise, it has created some problems encountered with low level and provoking noise (low frequency noise).
