Abstract:

In this paper, we introduce an advanced Fuzzy Record Similarity Metric (FRMS) that improves approximate record matching and models human perception of record similarity. The FRMS utilizes a newly developed similarity space with favorable properties combined with a metric space, employing a bag-of-words model with general applications in text mining and cluster analysis. To optimize the FRMS, we propose a two-stage method for approximate string matching and search that outperforms baseline methods in terms of average time complexity and F measure on various datasets. In the first stage, we cons

Abstract <strong>Background/Objectives:</strong> In this study, a term weighting scheme derived from probabilistic multiple correlation is defined for measuring similarity between unstructured text records. <strong>Methods:</strong> While the intra-correlation is the correlation of terms in the same record, inter-correlation is the correlation of terms that exist in different records. Probabilistic multiple correlation-based term weighting calculates the weight or relevance of a term by considering its intra-correlation with one or more terms simultaneously. Subsequently, the te

Abstract:

It is important to eliminate systematic biases in the field of soil moisture data assimilation. One simple method for bias removal is to match cumulative distribution functions (CDFs) of modeled soil moisture data to satellite soil moisture data. Traditional methods approximate numerical CDFs using 12 or 20 uniformly spaced samples. In this paper, we applied the Douglas–Peucker curve approximation algorithm to approximate the CDFs and found that three nonuniformly spaced samples can achieve the same reduction in standard deviation. Meanwhile, the matching results are always closely related to

Abstract:

Private record linkage (PRL) is the problem of identifying pairs of records that approximately match across datasets in a secure, privacy-preserving manner. Two-party PRL specifically allows each of the parties to obtain records from the other party, only given that each record matches with one of their own. The privacy goal is that no other information about the datasets should be released than the matching records. A fundamental challenge is not to leak information while at the same time not comparing all pairs of records. In plaintext record linkage this is done using a blocking strategy, e

Abstract:

Private matching for compute (PMC) establishes a match between two datasets owned by mutually distrusted parties (C and P) and allows the parties to input more data for the matched records for arbitrary downstream secure computation without rerunning the private matching component. The state-of-the-art PMC protocols only support two parties and assume that both parties can participate in computationally intensive secure computation. We observe that such operational overhead limits the adoption of these protocols to solely powerful entities as small data owners or devices with minimal computing

A comparative active experiment that is aimed at collocated measurement of seismic rotation rates along three orthogonal axes by means of three different methods is described. The rotation rates in a short-period range of 6–20 Hz were obtained using three different methods: the 6C Rotaphone sensor system developed by the authors, the commercial R-1 rotational sensor by Eentec, and a small-aperture array of twelve standard velocigraphs in a rectangular arrangement. Those three methods are compared and discussed in detail. A medium-size quarry blast was used as a seismic source. At a distance of

Abstract:

Data cleaning remains one of the most time-consuming and critical steps in modern data science, directly influencing the reliability and accuracy of downstream analytics. In this paper, we present a comprehensive evaluation of five widely used data cleaning tools—OpenRefine, Dedupe, Great Expectations, TidyData (PyJanitor), and a baseline Pandas pipeline—applied to large-scale, messy datasets spanning three domains (healthcare, finance, and industrial telemetry). We benchmark each tool on dataset sizes ranging from 1 million to 100 million records, measuring execution time, memory usage, error

Abstract:

AbstractTiny sinuous trace fossils have been found within probable gut contents of an exceptionally preserved specimen of a hadrosaurid dinosaur,Brachylophosaurus canadensis, from the Judith River Formation of Montana. Approximately 280 examples of the trace fossils were observed in 19 samples of gut region material. The tubular structures typically are about 0.3 mm across. Many have thin calcareous linings or layers, and some exhibit fine surficial striae. At least two dozen of these trace fossils share walls with adjacent tubular traces, and this association can extend for several millimeter

Abstract:

Over the past eight years, north-central Oklahoma has experienced a significant increase in seismicity. Although the disposal of large volumes of wastewater into the Arbuckle Group basement system has been statistically correlated to this increased seismicity, our understanding of the actual mechanisms involved is somewhat superficial. To address this shortcoming, we initiated an integrated study to characterize and model the Arbuckle-basement system to increase our understanding of the subsurface dynamics during the wastewater-disposal process. We constructed a 3D geologic model that integrat

Abstract Background: 40-80 % of patients with myelodysplastic syndrome (MDS) become transfusion dependent during their disease course and are at risk for the development of alloimmunization. Red blood cell (RBC) alloantibodies can make finding compatible blood for transfusion more difficult, expensive and time consuming. Allommunization rates of approximately 30-47% have been reported in patients with sickle cell disease and the transfusion of RBCs prophylactically matched for Rh antigens E and C, and K antigens reduced the rate of alloimmunization from 3% to 0.5% per unit (Vichinsky et al, 20

Introduction: Delirium is a common and debilitating clinical complication among ICU patients. Despite the prevalence of this condition, there are insufficient data to support or refute the routine use of atypical antipsychotics since the existing evidence remains sparse and inconclusive. The objective of the present study was to evaluate whether pre-ICU administration of the atypical antipsychotic olanzapine is associated with a differential time to delirium resolution relative to the control condition.

Five-year survival for ovarian cancer has increased from 36% for women who were diagnosed in 1975-1977 to 46% for women diagnosed between 2005-2011. Long term follow-up studies among ovarian cancer survivors are uncommon and late effects have not been well characterized in a population-based cohort. Although genitourinary complications during treatment are well known, long term impacts need to be investigated.

Abstract:

Abstract Motivation Adaptive immune receptor (AIR) repertoires (AIRRs) record past immune encounters with exquisite specificity. Therefore, identifying identical or similar AIR sequences across individuals is a key step in AIRR analysis for revealing convergent immune response patterns that may be exploited for diagnostics and therapy. Existing methods for quantifying AIRR overlap scale poorly with increasing dataset numbers and sizes. To address this limitation, we developed CompAIRR, which enables ultra-fast computation of AIRR overlap, based on either exact or approximate sequence matching.

Abstract:

Abstract Interferometric scattering microscopy (iSCAT) enables tracking single nano-objects in three dimensions (3D). Conventional image processing methods for 3D localization in iSCAT typically rely on template matching, which involves finding the maximum cross-correlation with modeled interferometric point spread functions (iPSFs). However, this approach can be computationally intensive and hinders the processing of nano-object movements on a large scale. In this study, we introduce an efficient analytical fitting approach for retrieving the 3D positions of nano-objects in wide-field iSCAT.
