Recent Advances (2023–2025) of Capillary Electrophoresis‐Mass Spectrometry (CE‐MS) for Top‐Down Proteomics

Mass Spectrometry Reviews, EarlyView.
ABSTRACT Top‐down proteomics (TDP) characterizes proteoforms in cells, tissues, and biofluids, in discovery mode and on a global scale, requiring analytical tools with high peak capacity for proteoform separation and high sensitivity for proteoform detection, given the extremely high proteoform complexity and wide proteoform concentration dynamic range.

Low-power SAR ADCs: trends, examples and future

ESSCIRC 2019 - IEEE 45th European Solid State Circuits Conference (ESSCIRC), 2019
With the development of mobile devices and Internet-of-Things,the demand for low-power circuits has been growing rapidly. The Analog-to-Digital Converter (ADC) is a key building block in these systems. In this work,we review the progress of low-power ADCs over the years in terms of performance and limitations. From these limitations,it can be shown why

Noise shaping in SAR ADC

Facta universitatis - series: Electronics and Energetics, 2020
The successive approximation register (SAR) analog-to-digital converter (ADC) is currently the most popular type of ADC architecture, owing to its power efficiency. They are also used in multichannel systems, where power efficiency is of high importance because of the large number of simultaneously working channels.

Optimized Reduced Field of View and Fat Suppression Methods for Interleaved Multislice In Vivo Cardiac Diffusion Tensor Imaging

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Slice interleaving, a limited phase encode (PE) field of view (FOV), and effective fat suppression are vital for efficient cardiac diffusion tensor imaging (cDTI) with minimal artifacts. This study aimed to optimize reduced FOV and fat suppression methods for interleaved multislice cDTI to improve signal‐to‐noise ratio (SNR) and ...
