Location‐Assisted Graph‐Based User Scheduling in Multi‐User MIMO LEO NTN Systems

International Journal of Satellite Communications and Networking, EarlyView.
ABSTRACT This paper addresses user clustering and scheduling for multi‐user MIMO low Earth orbit nonterrestrial network systems in full frequency reuse. Since the number of on‐ground user terminals is usually much higher than the number of on‐board LEO satellite antennas, user scheduling becomes a fundamental task.

Machine Learning‐Driven Nanopore Sensing for Quantitative, Label‐Free miRNA Detection

Small Methods, EarlyView.
Nanopore sensors combined with DNA‐barcoded probes enable detection of multiple biomarkers in parallel at the single‐molecule level through characteristic delays in ionic current signals. Three analytical strategies are compared: moving standard deviation, spectral entropy, and a convolutional neural network (CNN). The CNN achieves superior sensitivity

B‐Cell Repertoire of Children With Atopic Dermatitis Exhibits Altered IgE Maturation Associated With Allergic Food Sensitization

Allergy, EarlyView.
IgH repertoire sequencing of a large atopic dermatitis cohort reveal reduced IgE somatic hypermutation and increased IgE diversity associated with food allergen sensitization. Presence of a dog during the first year of life is associated with increased IgE somatic hypermutation, possibly countering the effect of food sensitization.

A Multicarrier Multiplexing Method for Very Wide Bandwidth Transmission

EURASIP Journal on Wireless Communications and Networking, 2006
The multicarrier orthogonal code division multiplexing (MC-OCDM) introduced here has been designed for very wide bandwidth (VWB) point-to-point and point-to-multipoint transmission.

High Concordance of Copy Number Variants Detected by Chromosomal Microarray and Exome Sequencing in Clinical Diagnostics

Clinical Genetics, EarlyView.
To assess the relevance of exome sequencing as a first‐tier diagnostic tool, three aspects were investigated: detection of copy number variants (CNVs) from exomes as compared to chromosomal microarray, clinically‐relevant CNVs across all sizes, and additional diagnostic utilities (uniparental disomy and triploidy).

Channel estimation and performance analysis for uplink SCMA system

Dianxin kexue, 2017
There are two types of physical mapping for SCMA named RE-Sparse SCMA and RB-Sparse SCMA.A frequency division multiplexing (FDM) based pilot pattern was proposed for RE-Sparse SCMA,and existing code division multiplexing pilot patterns based on cyclic ...
