For the pre-acidized shale, the non-linear deformation and elastoplasticity must be considered into the fracture propagation model. The previous research presented many effective numerical simulation methods for modeling the fracture propagation of hydraulic fracturing. However, the acidizing effects on ...
Clearly, there is an urgent need to implement and research new methods of psychological help for students. Our study addresses this need and may have important practical implications. Nevertheless, these strengths will probably be associated with limitations. First, previous research findings have ...
We investigate the pattern of the main trend over time, linking it to attention to Brexit using linear regression and Google Trends data. Background and literature review The study of migration has historically relied on data and statistics from national and super-national institutions and ...
The estimation process is identical to that of eventstudyinteract, and this package used FixedEffectModels.jl to implement the Stata command reghdfe functionality. As introduced in the Stata package eventstudyinteract provided by Sun and Abraham (2021), the function of this package is: eventstudy...
Coronavirus disease 2019 (COVID-19) vaccines demonstrate excellent effectiveness against infection, severe disease, and death. However, pediatric COVID-19 vaccination rates lag among individuals from rural and other medically underserved communities. The
We compare classic fixed and random-effects models with machine learning algo- rithms, which outperformed standard strategies with unclustered data when the link between the treatment and the covariates is not linear and additive. We found that a novel algorithm, Generalized Mixed Effect Regression ...
Implementation and results Seven machine-learning models were implemented using the Matlab and Scikit-Learn programming libraries. Matlab was used to implement six of the models: LR, SVM, NN, DT, EoT, and GPR. The XGBoost model was implemented and exploited using the Scikit-Learn library (Pedreg...
Using machine learning methods to analyze the fatigue status of medical security personnel and the factors influencing fatigue (such as BMI, gender, and wearing protective clothing working hours), with the goal of identifying the key factors contributing
Next, we closely inspected the resulting factors in order to determine whether the items fit together semantically and whether they implement the same design requirement for a LAD. Factor 1 Transparency of the design - groups five items that include the word “explanations”, suggesting that they ...
Correction for possible confounders was applied in linear regression analyses. In patients who discontinued treatment due to ineffectiveness and/or AEs, PASI scores at discontinuation were carried forward using the last observation carried forward (LOCF) method. With this method, PASI scores in the ...
