Classification of Precipitable Water Vapor Regimes Revealed by Clustering of GNSS Radio Occultation and ERA5 Data

Earth and Space Science, Volume 13, Issue 8, August 2026.
Abstract Precipitable water vapor (PWV) is an essential parameter for the study of weather and climate behavior. This work presents a novel regional classification of PWV regimes based on clustering techniques applied to Global Navigation Satellite System radio occultation‐derived and ERA5 reanalysis data with and without seasonal removal.

Piecewise Dynamic Time Warping-Based Subsequence Matching in Data Stream

IEEE Access
Dynamic Time Warping (DTW) is effective for subsequence matching but is limited by its high computational cost. To address this challenge, we propose a method that adaptively segments data streams and extracts Chebyshev features for piecewise ...

Temporal Drivers of Opioid‐Related ED Visits: An Ensemble Machine Learning Study With Consensus‐Based Feature Attribution

Clinical and Translational Science, Volume 19, Issue 8, August 2026.
ABSTRACT Identification of modifiable risk factors for prescription opioid use disorder (OUD)‐related emergency department (ED) visits (ICD‐10 F11.xx) is a clinical priority; however, most published models remain cross‐sectional and lack pharmacogenomic (PGx) enrichment or dual‐method feature confirmation. Using Virginia All‐Payer Claims Database (APCD)

A Serverless Pharmacogenomic Risk Dashboard: Translating Ensemble Models and Model‐Based Scenario Rules to Clinical Decision Support

Clinical and Translational Science, Volume 19, Issue 8, August 2026.
ABSTRACT The “last mile” problem in healthcare AI—translating high‐performance models into accessible, privacy‐preserving point‐of‐care tools—remains unsolved for pharmacogenomic (PGx) risk assessment. No existing platform integrates opioid and polypharmacy risk scoring, model‐based scenario analysis, and CPIC‐based PGx patient cards within a single ...

Enhancing Nearest Neighbor Classification Performance through Dynamic Time Warping with Progressive Constraint

Proceedings of the International Florida Artificial Intelligence Research Society Conference
Dynamic time warping (DTW) is a widely used metric for comparing time series data, offering elasticity in alignment. While the original DTW allows infinite elasticity without penalty, the wDTW imposes a constant penalty regardless of elastic length.

The use of geographic information systems and remote sensing to evaluate climate change effect on groundwater: application to Mostaganem Plateau, Northwest Algeria

Acque Sotterranee
Effects of climate change in semi-arid areas occur in drought events, which affect aquifers whose recharge depends essentially on precipitation.

Assessing the matching degree between environmental loading and GNSS time series with an improved DTW method

Discover Applied Sciences
The GNSS time series is affected by hydrological loading (HYDL) associated with water storage, non-tidal atmospheric loading (NTAL), and non-tidal oceanic loading (NTOL) in the Earth’s surface, potentially leading to time lag phenomena and nonlinear ...

The clinical characteristics of cerebral small vessel disease patients with motoric cognitive risk syndrome during single- and dual-task walking

Heliyon
Objective: We aimed to (1) identify neuroimaging biomarkers of distinguishing motoric cognitive risk syndrome (MCRS) risk among older Chinese adults with cerebral small vessel disease (CSVD) and (2) detect differences in gait parameters and neuroimaging ...
