Introduction YouTube is a popular social media used by youth and has electronic cigarette (e-cigarette) content. We machine learning to identify the content of e-cigarette videos, featured products, video uploaders, marketing sales products. Methods identified using 18 search terms (eg, e-cig) fictitious viewer profiles predicted four models metadata as input supervised learning: (1) themes, (2) (3) channel type (ie, uploaders) (4) discount/sales. assessed association between engagement data...
Nucleation of salt crystals in confined media occurs many processes high importance, such as injection CO2 geological formations for its sequestration. In particular, precipitation clays, a main component sedimentary rock, is an important phenomenon. The precipitate on the pores' surface, modify pore space morphology, and reduce flow transport properties. Despite numerous efforts to understand mechanisms nucleation media, effect clay's chemistry growth, distribution, properties not well...
The risk of CO2 and brine leakage to environmental receptors is one the main concerns associated with geologic storage. Legacy wells oil gas activities are abundant may be found within area review some storage projects. If legacy present a project area, they will require constant surveillance ensure properly completed plugged prevent fluid transmission. Hence, deployment an efficient monitoring system for early detection from failed imperative mitigate financial risks.The objective our study...
Hurricane track forecasting remains a significant challenge due to the complex interactions between atmosphere, land, and ocean. Although AI-based numerical weather prediction models, such as Google Graphcast operation, have significantly improved hurricane forecasts, they currently function atmosphere-only omitting critical land ocean interactions. To investigate impact of feedback, we conducted independent simulations using physics-based WRF experimental model assess how soil moisture...
Abstract Archie's law expresses a relation between the formation factor F of porous media and their porosity ϕ , where m is Archie or cementation exponent. Despite widespread use law, value whether it universal independent type reservoir have remained controversial. We analyze various resistivity logs along 36 wells in six Iranian oil gas reservoirs using wavelet transform coherence multifractal detrended fluctuation analysis. estimated for two sets data: one set contains data that include...
The proliferation of e-cigarette content on YouTube is concerning because its possible effect youth use behaviors. has a personalized search and recommendation algorithm that derives attributes from user's profile, such as age sex. However, little known about whether shown differently based user characteristics.
Background e-Cigarette use among youth is high, which may be due in part to pro–e-cigarette content on social media such as YouTube. YouTube also a valuable resource for learning about e-cigarette use, trends, marketing, and user perceptions. However, there lack of understanding how similar e-cigarette–related search items result or relatively mutually exclusive results. This study uses novel methods evaluate the relationship between Objective The aim this apply network modeling rule-based...
Background. After a year and half over 4 million deaths, the COVID-19 pandemic continues to be widespread, its related topics continue dominate global media. Although diagnoses have been well monitored, neither impacts of disease on human behavior social dynamics nor effectiveness policy interventions aimed at containment are fully understood. Monitoring spatial temporal patterns behavior, policy—and then their interrelations—can provide critical information for preparatory action effective...
Geophysical data contain stochastic noise that may mask their useful content. For example, ground roll (GR) is a coherent present in seismic data. Thus, such are usually mixture of information and useless noise. The latter masks the relevant geologic records contain, its removal has always been problem fundamental importance. We propose denoising method based on curvelet transformation (CT), multiscale with strong directional character provides an optimal representation objects have...

This study presents an innovative approach to creating a dynamic, AI based emission inventory system for use with the Weather Research and Forecasting model coupled Chemistry (WRF Chem), designed simulate vehicular other anthropogenic emissions at satellite detectable resolution. The methodology leverages state of art deep learning computer vision models, primarily employing YOLO (You Only Look Once) architectures (v8 v10) T Rex, high precision object detection. Through extensive data...
This research explores the application of Advanced Integral Equation Model (AIEM) for retrieving surface soil moisture in grassland ecosystems. The AIEM was utilized to analyze VV-polarized backscatter coefficients obtained from Sentinel-1, incorporating Sentinel-2-derived NDVI address challenge separating and vegetation scattering contributions grasslands. Calibration model performed using field measurements Texas Soil Observation Network (TxSON), spanning 2019 2021. estimates derived were...
The deformation of clay minerals is an important phenomenon that relevant to many problems, particularly those occur in subsurface geological formations. salinity the formations and external shear stress applied them are two factors contribute such porous media. To gain a deeper understanding phenomena, we have carried out extensive molecular dynamics simulations using Na-montmorillonite (Na-MMT) structure as model studied effect salt concentration on its swelling. As NaCl increases, so also...
Abstract Seismic data usually contain stochastic noise, such as the ground roll (GR), a coherent noise. The noise masks useful content of data, geologic information that seismic records contain. Removal has always been problem fundamental importance. There are already several methods for removing from images, almost all which have drawback they degrade both noisy and “unpolluted” regions in images. In addition, typically long-range correlations, characterized by Hurst exponent H. this study...
