A low noise CMOS camera system for 2D resonant inelastic soft X-ray scattering
Frontiers in Physics, 2023 Resonant Inelastic X-ray Scattering (RIXS) is a powerful spectroscopic technique to study quantum properties of materials in the bulk. A novel variant of RIXS, called 2D RIXS, enables concurrent measurement of the scattered X-ray spectrum for a wide ...

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 ...

Noise-optimized ultrastable low-noise current amplifier [PDF]
Review of Scientific Instruments, 2019 We have developed a noise-optimized ultrastable low-noise current amplifier (ULCA) aimed at reducing the uncertainty at low currents. It involves a thin-film resistor network with 6.75 GΩ at the high-ohmic path which reduces the noise level to 1.6 fA/Hz. Noise investigations as well as short-term and long-term stability studies were carried out.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization
Molecular Oncology, EarlyView.In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Molecular Oncology, EarlyView.Matched spatial transcriptomics and single‐nuclei RNA‐seq were generated for anaplastic and BRAFV600E papillary thyroid cancers revealing generic and tumor‐specific states occurring in cancer cells and in the tumor microenvironment. In this context, cancer dedifferentiation mirrored organoid maturation through ordered thyroid marker gain/loss ...

Low-discrepancy blue noise sampling [PDF]
ACM Transactions on Graphics, 2016 We present a novel technique that produces two-dimensional low-discrepancy (LD) blue noise point sets for sampling. Using one-dimensional binary van der Corput sequences, we construct two-dimensional LD point sets, and rearrange them to match a target spectral profile while preserving their low discrepancy.

A low‐noise current‐reused CMOS active inductor by exploiting Gm‐boosting technique
IET Microwaves, Antennas & Propagation, 2021 This work introduces a new low‐noise current‐reused CMOS active inductor (AI) based on Gyrator‐C configuration. In the proposed AI, a simple common‐source amplifier is utilised for boosting effective Gm and improving noise performance of the AI.

Down With Noise: An Introduction to a Low-Noise Amplifier Survey
IEEE Solid-State Circuits Magazine, 2020 Numerous different circuits are created around the world on a daily basis, making it rather difficult for circuit designers to stay abreast of the latest developments. In an attempt to keep up with these new developments, researchers have compiled a number of spreadsheets that capture key designs and their features.
