ADC bit allocation under a power constraint for mmWave massive MIMO communication receivers

open access: yes, 2017
Millimeter wave (mmWave) systems operating over a wide bandwidth and using a large number of antennas impose a heavy burden on power consumption. In a massive multiple-input multiple-output (MIMO) uplink, analog-to-digital converters (ADCs) would be the ...

Quantifying temporal dynamics of greenhouse gas emissions in lake mesocosms: Deployment of a low‐cost measurement system

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Greenhouse gas (GHG) emissions from freshwater ecosystems contribute significantly to global carbon budgets, yet they remain poorly constrained due to limited high‐frequency measurements. We tested a low‐cost, high‐frequency GHG measurement system in a long‐term mesocosm experiment in Lemming, Denmark, over a 7‐month period, focusing on CO2 ...

The Impact of SAR-ADC Mismatch on Quantized Massive MU-MIMO Systems

open access: yes, 2023
Low-resolution analog-to-digital converters (ADCs) in massive multi-user (MU) multiple-input multiple-output (MIMO) wireless systems can significantly reduce the power, cost, and interconnect data rates of infrastructure basestations.

Loop Quantum Photonic Chip for Coherent Multi‐Time‐Step Evolution

open access: yesLaser &Photonics Reviews, EarlyView.
A loop quantum photonic chip (Loop‐QPC) enabling efficient multi‐step quantum simulation in a single run is demonstrated. Combining recirculating loops with cycle‐or‐measure control, Loop‐QPC eliminates repeated reprogramming and reduces loss. Experimental demonstration of three‐step unitary evolution confirms high‐fidelity operation, showcasing the ...

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

open access: yesMass 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.

Cell-free mmWave massive MIMO systems with low-capacity fronthaul lnks and low-resolution ADC/DACs

open access: yes, 2022
In this paper, we consider the uplink channel estimation phase and downlink data transmission phase of cell-free millimeter wave (mmWave) massive multiple-input multiple-output (MIMO) systems with low-capacity fronthaul links and low-resolution analog-to-

From Uncertainty to Pathogenicity: Resolving a CSF1R Variant of Uncertain Significance Using Long‐Read Transcriptomics

open access: yesMovement Disorders, EarlyView.
Abstract Background CSF1R‐related disorder (CSF1R‐RD) is a severe autosomal dominant leukoencephalopathy characterized by progressive cognitive, neuropsychiatric, and motor decline. Although genetic testing is widely available, numerous likely pathogenic variants in CSF1R frequently remain classified as variants of uncertain significance (VUS ...
