Breakthrough Solution for Antimicrobial Resistance Detection: Surface‐Enhanced Raman Spectroscopy‐based on Artificial Intelligence

Advanced Materials Interfaces, EarlyView., 2023
This review discusses the use of Surface‐Enhanced Raman Spectroscopy (SERS) combined with Artificial Intelligence (AI) for detecting antimicrobial resistance (AMR). Various SERS studies used with AI techniques, including machine learning and deep learning, are analyzed for their advantages and limitations.

Detecting homologous recombination deficiency for breast cancer through integrative analysis of genomic data

Molecular Oncology, EarlyView.
This study develops a semi‐supervised classifier integrating multi‐genomic data (1404 training/5893 validation samples) to improve homologous recombination deficiency (HRD) detection in breast cancer. Our method demonstrates prognostic value and predicts chemotherapy/PARP inhibitor sensitivity in HRD+ tumours.

Research on Huffman algorithm based on PCA and SPIHT for image compression(基于主成分分析和分层树集合划分的Huffman算法图像压缩研究)

Zhejiang Daxue xuebao. Lixue ban, 2018
互联网的飞速发展，产生了大量的图像信息.为了减少图片占用的存储空间，提高图像质量，提出了一种将主成分分析(PCA)和分层树集合划分(SPIHT)压缩算法相结合的有损图像压缩算法.首先对图像进行主成分分解，选取主要特征值进行压缩，再利用SPIHT算法将图像分解成不同子带的小波系数进行压缩，对SPIHT压缩系数进行哈夫曼编码，实现图像二级压缩.将本文提出的算法与SPIHT、SPIHT的哈夫曼编码、JEPG2000、PCA压缩算法进行了比较，结果表明本算法较其他压缩算法具有更好的性能 ...

Morphotype and multivariate analysis of the occlusal pattern of the first lower molar in European and Asian arvicoline species (Rodentia, Microtus, Alexandromys)

Zoodiversity, 2020
We studied the morphotypic variation of the occlusal pattern of m1 in 13 arvicoline species (genera Microtus and Alexandromys). As a result, 22 m1 morphotypes were identified.

Local PCA Shows How the Effect of Population Structure Differs Along the Genome

Genetics, 2016
Principal component analysis (PCA) is often used to describe overall population structure—patterns of relatedness arising from past demographic history—among a set of genomes. Here, Li and Ralph describe how the patterns uncovered by....

TRPM8 levels determine tumor vulnerability to channel agonists

Molecular Oncology, EarlyView.
TRPM8 is a Ca2+ permissive channel. Regardless of the amount of its transcript, high levels of TRPM8 protein mark different tumors, including prostate, breast, colorectal, and lung carcinomas. Targeting TRPM8 with channel agonists stimulates inward calcium currents followed by emptying of cytosolic Ca2+ stores in cancer cells.

Comprehensive omics‐based classification system in adult patients with B‐cell acute lymphoblastic leukemia

Molecular Oncology, EarlyView.
The COMBAT classification system, developed through multi‐omics integration, stratifies adult patients with B‐cell acute lymphoblastic leukemia(B‐ALL) into three molecular subtypes with distinct surface antigen patterns, immune landscape, methylation patterns, biological pathways and prognosis.

Functional Factors of Biomass Burning Contribution to Spring Aerosol Composition in a Megacity: Combined FTIR-PCA Analyses

Atmosphere, 2020
Whether the spring season brings additional pollution to the urban environment remains questionable for a megacity. Aerosol sampling and characterization was performed in the urban background of the Moscow megacity in spring 2017, in a period of a ...
