A Survey of Neural Front End Amplifiers and Their Requirements toward Practical Neural Interfaces
Journal of Low Power Electronics and Applications, 2014 When designing an analog front-end for neural interfacing, it is hard to evaluate the interplay of priority features that one must upkeep. Given the competing nature of design requirements for such systems a good understanding of these trade-offs is ...

Journal of Research of the National Bureau of Standards, 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 [Formula: see text] and 0.25 [Formula: see text] over the 500 Hz to 50 kHz frequency range. The amplifier is presently being used in conjunction with a Penning ion trap but is applicable to a wide ...

Flow structure and unsteady characteristics of fountain flow induced by dual impinging jets
Kongqi donglixue xuebaoThe flow-field structure and mechanical characteristics of dual impinging jets are critical issues during the takeoff and landing phases of aircraft. However, the unsteady characteristics of the fountain effect induced by dual impinging jets have not yet

A method for lift coefficient estimation of a pantograph using sparse modelling
Nihon Kikai Gakkai ronbunshu, 2018 It is necessary for pantographs of Japanese high-speed trains to satisfy both low noise characteristics and insensitive lift force characteristics toward the variation in wind direction and in the shape of pantograph head due to wear.

Label-Free Biomedical Imaging Using High-Speed Lock-In Pixel Sensor for Stimulated Raman Scattering
Sensors, 2017 Raman imaging eliminates the need for staining procedures, providing label-free imaging to study biological samples. Recent developments in stimulated Raman scattering (SRS) have achieved fast acquisition speed and hyperspectral imaging.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Study on Noise Reduction with Paving Different Low Noise Pavement Materials
Applied Sciences, 2021 This paper evaluates the amount of noise reduction when using different pavement materials in two adjacent lanes, where the close-proximity (CPX) method is introduced to analyze the tire/road noise before and after pavement maintenance.

Electron transfer between complexes III and IV in S. cerevisiae mitochondrial membranes
FEBS Letters, EarlyView.Mitochondrial oxidative phosphorylation in S. cerevisiae mitoplasts is limited by complex IV catalytic capacity, rather than two‐dimensional cytochrome c diffusion. At physiological cytochrome c : supercomplex ratios at salinity equivalent to that of 20 mm monovalent salt, activity is maximized, indicating that this low ionic strength accurately mimics
