Background The Infinium EPIC array measures the methylation status of > 850,000 CpG sites. The EPIC BeadChip uses a two-array design: Infinium Type I and Type II probes. These probe types exhibit different technical characteristics which may confound analyses. Numerous normalization and pre-processing methods have been developed to reduce probe type bias as well as other issues such as background and dye bias.
Methods This study evaluates the performance of various normalization methods using 16 replicated samples and three metrics: absolute beta-value difference, overlap of non-replicated CpGs between replicate pairs, and effect on beta-value distributions. Additionally, we carried out Pearson’s correlation and intraclass correlation coefficient (ICC) analyses using both raw and SeSAMe 2 normalized data.
Results The method we define as SeSAMe 2, which consists of the application of the regular SeSAMe pipeline with an additional round of QC, pOOBAH masking, was found to be the best-performing normalization method, while quantile-based methods were found to be the worst performing methods. Whole-array Pearson’s correlations were found to be high. However, in agreement with previous studies, a substantial proportion of the probes on the EPIC array showed poor reproducibility (ICC < 0.50). The majority of poor-performing probes have beta values close to either 0 or 1, and relatively low standard deviations. These results suggest that probe reliability is largely the result of limited biological variation rather than technical measurement variation. Importantly, normalizing the data with SeSAMe 2 dramatically improved ICC estimates, with the proportion of probes with ICC values > 0.50 increasing from 45.18% (raw data) to 61.35% (SeSAMe 2). Methods

Study Participants and Samples

The whole blood samples were obtained from the Health, Well-being and Aging (Saúde, Ben-estar e Envelhecimento, SABE) study cohort. SABE is a cohort of census-withdrawn elderly from the city of São Paulo, Brazil, followed up every five years since the year 2000, with DNA first collected in 2010. Samples from 24 elderly adults were collected at two time points for a total of 48 samples. The first time point is the 2010 collection wave, performed from 2010 to 2012, and the second time point was set in 2020 in a COVID-19 monitoring project (9±0.71 years apart). The 24 individuals were 67.41±5.52 years of age (mean ± standard deviation) at time point one; and 76.41±6.17 at time point two and comprised 13 men and 11 women.

All individuals enrolled in the SABE cohort provided written consent, and the ethic protocols were approved by local and national institutional review boards COEP/FSP/USP OF.COEP/23/10, CONEP 2044/2014, CEP HIAE 1263-10, University of Toronto RIS 39685.

Blood Collection and Processing

Genomic DNA was extracted from whole peripheral blood samples collected in EDTA tubes. DNA extraction and purification followed manufacturer’s recommended protocols, using Qiagen AutoPure LS kit with Gentra automated extraction (first time point) or manual extraction (second time point), due to discontinuation of the equipment but using the same commercial reagents. DNA was quantified using Nanodrop spectrometer and diluted to 50ng/uL. To assess the reproducibility of the EPIC array, we also obtained technical replicates for 16 out of the 48 samples, for a total of 64 samples submitted for further analyses. Whole Genome Sequencing data is also available for the samples described above.

Characterization of DNA Methylation using the EPIC array

Approximately 1,000ng of human genomic DNA was used for bisulphite conversion. Methylation status was evaluated using the MethylationEPIC array at The Centre for Applied Genomics (TCAG, Hospital for Sick Children, Toronto, Ontario, Canada), following protocols recommended by Illumina (San Diego, California, USA).

Processing and Analysis of DNA Methylation Data

The R/Bioconductor packages Meffil (version 1.1.0), RnBeads (version 2.6.0), minfi (version 1.34.0) and wateRmelon (version 1.32.0) were used to import, process and perform quality control (QC) analyses on the methylation data. Starting with the 64 samples, we first used Meffil to infer the sex of the 64 samples and compared the inferred sex to reported sex. Utilizing the 59 SNP probes that are available as part of the EPIC array, we calculated concordance between the methylation intensities of the samples and the corresponding genotype calls extracted from their WGS data. We then performed comprehensive sample-level and probe-level QC using the RnBeads QC pipeline. Specifically, we (1) removed probes if their target sequences overlap with a SNP at any base, (2) removed known cross-reactive probes (3) used the iterative Greedycut algorithm to filter out samples and probes, using a detection p-value threshold of 0.01 and (4) removed probes if more than 5% of the samples having a missing value. Since RnBeads does not have a function to perform probe filtering based on bead number, we used the wateRmelon package to extract bead numbers from the IDAT files and calculated the proportion of samples with bead number < 3. Probes with more than 5% of samples having low bead number (< 3) were removed. For the comparison of normalization methods, we also computed detection p-values using out-of-band probes empirical distribution with the pOOBAH() function in the SeSAMe (version 1.14.2) R package, with a p-value threshold of 0.05, and the combine.neg parameter set to TRUE. In the scenario where pOOBAH filtering was carried out, it was done in parallel with the previously mentioned QC steps, and the resulting probes flagged in both analyses were combined and removed from the data.

Normalization Methods Evaluated

The normalization methods compared in this study were implemented using different R/Bioconductor packages and are summarized in Figure 1. All data was read into R workspace as RG Channel Sets using minfi’s read.metharray.exp() function. One sample that was flagged during QC was removed, and further normalization steps were carried out in the remaining set of 63 samples. Prior to all normalizations with minfi, probes that did not pass QC were removed. Noob, SWAN, Quantile, Funnorm and Illumina normalizations were implemented using minfi. BMIQ normalization was implemented with ChAMP (version 2.26.0), using as input Raw data produced by minfi’s preprocessRaw() function. In the combination of Noob with BMIQ (Noob+BMIQ), BMIQ normalization was carried out using as input minfi’s Noob normalized data. Noob normalization was also implemented with SeSAMe, using a nonlinear dye bias correction. For SeSAMe normalization, two scenarios were tested. For both, the inputs were unmasked SigDF Sets converted from minfi’s RG Channel Sets. In the first, which we call “SeSAMe 1”, SeSAMe’s pOOBAH masking was not executed, and the only probes filtered out of the dataset prior to normalization were the ones that did not pass QC in the previous analyses. In the second scenario, which we call “SeSAMe 2”, pOOBAH masking was carried out in the unfiltered dataset, and masked probes were removed. This removal was followed by further removal of probes that did not pass previous QC, and that had not been removed by pOOBAH. Therefore, SeSAMe 2 has two rounds of probe removal. Noob normalization with nonlinear dye bias correction was then carried out in the filtered dataset. Methods were then compared by subsetting the 16 replicated samples and evaluating the effects that the different normalization methods had in the absolute difference of beta values (|β|) between replicated samples.

Data normalization is vital to single-cell sequencing, addressing limitations presented by low input material and various forms of bias or noise present in the sequencing process. Several such normalization methods exist, some of which rely on spike-in genes, molecules added in known quantities to serve as a basis for a normalization model. Depending on available information and the type of data, some methods may express certain advantages over others. We compare the effectiveness of seven available normalization methods designed specifically for single-cell sequencing using two real data sets containing spike-in genes and one simulation study. Additionally, we test those methods not dependent on spike-in genes using a real data set with three distinct cell-cycle states and a real data set under the 10X Genomics GemCode platform with multiple cell types represented. We demonstrate the differences in effectiveness for the featured methods using visualization and classification assessment and conclude which methods are preferable for normalizing a certain type of data for further downstream analysis, such as classification or differential analysis. The comparison in computational time for all methods is addressed as well.

Objective: Normalizing mentions of medical concepts to standardized vocabularies is a fundamental component of clinical text analysis. Ambiguity—words or phrases that may refer to different concepts—has been extensively researched as part of information extraction from biomedical literature, but less is known about the types and frequency of ambiguity in clinical text. This study characterizes the distribution and distinct types of ambiguity exhibited by benchmark clinical concept normalization datasets, in order to identify directions for advancing medical concept normalization research.

Materials and Methods: We identified ambiguous strings in datasets derived from the two available clinical corpora for concept normalization, and categorized the distinct types of ambiguity they exhibited. We then compared observed string ambiguity in the datasets to potential ambiguity in the Unified Medical Language System (UMLS), to assess how representative available datasets are of ambiguity in clinical language.

Results: We observed twelve distinct types of ambiguity, distributed unequally across the available datasets. However, less than 15% of the strings were ambiguous within the datasets, while over 50% were ambiguous in the UMLS, indicating only partial coverage of clinical ambiguity.

Discussion: Existing datasets are not sufficient to cover the diversity of clinical concept ambiguity, limiting both training and evaluation of normalization methods for clinical text. Additionally, the UMLS offers important semantic information for building and evaluating normalization methods.

Conclusion: Our findings identify three opportunities for concept normalization research, including a need for ambiguity-specific clinical datasets and leveraging the rich semantics of the UMLS in new methods and evaluation measures for normalization.

Methods These data are derived from benchmark datasets released for Medical Concept Normalization research focused on Electronic Health Record (EHR) narratives. Data included in this release are derived from:

SemEval-2015 Task 14 (Publication DOI: 10.18653/v1/S15-2051, data accessed through release at https://physionet.org/content/shareclefehealth2014task2/1.0/)
CUILESS2016 (Publication DOI: 10.1186/s13326-017-0173-6, data accessed through release at https://physionet.org/content/cuiless16/1.0.0/)

These datasets consist of EHR narratives with annotations including: (1) the portion of a narrative referring to a medical concept, such as a problem, treatment, or test; and (2) one or more Concept Unique Identifiers (CUIs) derived from the Unified Medical Language System (UMLS), identifying the reification of the medical concept being mentioned.

The data were processed using the following procedure:

All medical concept mention strings were preprocessed with lowercasing and removing of determiners ("a", "an", "the").
All medical concept mentions were analyzed to identify strings that met the following conditions: (1) string occurred more than once in the dataset, and (2) string was annotated with at least two different CUIs, when aggregating across dataset samples. Strings meeting these conditions were considered "ambiguous strings".
Ambiguous strings were reviewed by article authors to determine (1) the category and subcategory of ambiguity exhibited (derived from an ambiguity typology described in the accompanying article); and (2) whether the semantic differences in CUI annotations were reflected by differences in textual meaning (strings not meeting this criterion were termed "arbitrary").

RXNORM source uses term types (TTYs) to indicate generic and branded drug names at different levels of specificity. This dataset includes the full list of term types, where source provider is RXNORM.

We performed CODEX (co-detection by indexing) multiplexed imaging on four sections of the human colon (ascending, transverse, descending, and sigmoid) using a panel of 47 oligonucleotide-barcoded antibodies. Subsequently images underwent standard CODEX image processing (tile stitching, drift compensation, cycle concatenation, background subtraction, deconvolution, and determination of best focal plane), and single cell segmentation. Output of this process was a dataframe of nearly 130,000 cells with fluorescence values quantified from each marker. We used this dataframe as input to 1 of the 5 normalization techniques of which we compared z, double-log(z), min/max, and arcsinh normalizations to the original unmodified dataset. We used these normalized dataframes as inputs for 4 unsupervised clustering algorithms: k-means, leiden, X-shift euclidian, and X-shift angular.

From the clustering outputs, we then labeled the clusters that resulted for cells observed in the data producing 20 unique cell type labels. We also labeled cell types by hiearchical hand-gating data within cellengine (cellengine.com). We also created another gold standard for comparison by overclustering unormalized data with X-shift angular clustering. Finally, we created one last label as the major cell type call from each cell from all 21 cell type labels in the dataset.

Consequently the dataset has individual cells segmented out in each row. Then there are columns for the X, Y position in pixels in the overall montage image of the dataset. There are also columns to indicate which region the data came from (4 total). The rest are labels generated by all the clustering and normalization techniques used in the manuscript and what were compared to each other. These also were the data that were used for neighborhood analysis for the last figure of the manuscript. These are provided at all four levels of cell type level granularity (from 7 cell types to 35 cell types).

Normalization of RNA-Seq data has proven essential to ensure accurate inferences and replication of findings. Hence, various normalization methods have been proposed for various technical artifacts that can be present in high-throughput sequencing transcriptomic studies. In this study, we set out to compare the widely used library size normalization methods (UQ, TMM, and RLE) and across sample normalization methods (SVA, RUV, and PCA) for RNA-Seq data using publicly available data from The Cancer Genome Atlas (TCGA) cervical cancer study. Additionally, an extensive simulation study was completed to compare the performance of the across sample normalization methods in estimating technical artifacts. Lastly, we investigated the effect of reduction in degrees of freedom in the normalized data and their impact on downstream differential expression analysis results. Based on this study, the TMM and RLE library size normalization methods give similar results for CESC dataset. In addition, the simulated datasets results show that the SVA (“BE”) method outperforms the other methods (SVA “Leek”, PCA) by correctly estimating the number of latent artifacts. Moreover, ignoring the loss of degrees of freedom due to normalization results in an inflated type I error rates. We recommend adjusting not only for library size differences but also the assessment of known and unknown technical artifacts in the data, and if needed, complete across sample normalization. In addition, we suggest that one includes the known and estimated latent artifacts in the design matrix to correctly account for the loss in degrees of freedom, as opposed to completing the analysis on the post-processed normalized data.

This exceptional growth is fueled by the urgent need for seamless data integration, real-time analytics, and interoperability across an increasingly fragmented EV charging ecosystem.

One of the primary growth factors propelling the EV Charging Data Normalization Platform market is the exponential rise in electric vehicle deployment worldwide. As both public and private sectors accelerate their commitments to decarbonization, the number of EVs on the road is expected to surpass 250 million units by 2030, according to industry forecasts. This proliferation demands a robust digital backbone that can harmonize disparate data streams from a multitude of charging stations, operators, and backend systems. Data normalization platforms are crucial in transforming raw, heterogeneous data into standardized formats, enabling utilities, fleet operators, and charging network providers to optimize operations, enhance user experience, and support predictive maintenance. The increasing complexity of charging networks, combined with the need for transparent billing, real-time monitoring, and regulatory compliance, further amplifies the demand for advanced data normalization solutions.

Another significant driver is the growing emphasis on interoperability and open standards within the EV charging landscape. With the entry of numerous hardware manufacturers, software vendors, and service providers, data silos have become a major operational bottleneck. The lack of standardized communication protocols and data formats impedes seamless integration, leading to inefficiencies and increased operational costs. EV Charging Data Normalization Platforms address this challenge by bridging the gap between diverse systems, facilitating cross-network roaming, and ensuring consistent data flows for analytics and reporting. This capability is particularly critical for fleet operators and utilities that must manage complex charging patterns across multiple geographies and hardware types. The rise of smart charging, dynamic load management, and integration with renewable energy sources further accentuates the need for sophisticated data normalization platforms capable of handling real-time, high-volume data streams.

Additionally, regulatory mandates and government incentives are playing a pivotal role in shaping the EV Charging Data Normalization Platform market. Many regions, particularly in Europe and North America, have introduced stringent requirements for data transparency, security, and interoperability. These regulations mandate the adoption of open data standards and encourage investments in digital infrastructure to support the scaling of EV charging networks. The availability of government grants, tax incentives, and public-private partnerships is accelerating the deployment of advanced data normalization solutions, particularly among commercial and utility end-users. Furthermore, the integration of artificial intelligence and machine learning into these platforms is opening new avenues for predictive analytics, demand forecasting, and grid optimization, providing a competitive edge to early adopters.

Regionally, Europe and North America are leading the adoption of EV Charging Data Normalization Platforms, driven by mature EV markets, comprehensive regulatory frameworks, and substantial investments in charging infrastructure. Asia Pacific, however, is emerging as a high-growth region, propelled by rapid urbanization, government-led electrification initiatives, and the expansion of domestic EV manufacturing. Latin America and the Middle East & Africa are also witnessing increased activity, albeit at a slower pace, as local governments and private players begin to recognize the strategic importance of data-driven EV charging ecosystems. Regional disparities in infrastructure maturity, regulatory standards, and technology adoption are influencing the pace and nature of market growth across different geographies.

Complex networks abound in physical, biological and social sciences. Quantifying a network’s topological structure facilitates network exploration and analysis, and network comparison, clustering and classification. A number of Wiener type indices have recently been incorporated as distance-based descriptors of complex networks, such as the R package QuACN. Wiener type indices are known to depend both on the network’s number of nodes and topology. To apply these indices to measure similarity of networks of different numbers of nodes, normalization of these indices is needed to correct the effect of the number of nodes in a network. This paper aims to fill this gap. Moreover, we introduce an -Wiener index of network , denoted by . This notion generalizes the Wiener index to a very wide class of Wiener type indices including all known Wiener type indices. We identify the maximum and minimum of over a set of networks with nodes. We then introduce our normalized-version of -Wiener index. The normalized -Wiener indices were demonstrated, in a number of experiments, to improve significantly the hierarchical clustering over the non-normalized counterparts.
