Petrophysical Regression regarding Porosity, Permeability, and Water Saturation Driven by Logging-Based Ensemble and Transfer Learnings: A Case Study of Sandy-Mud Reservoirs
Published 2022-01-01“…From a general review, most petrophysical models applied for the conventional logging interpretation imply that porosity, permeability, or water saturation mathematically have a linear or nonlinear relationship with well logs, and then arguing the prediction of these three parameters actually is accessible under a regression of logging sequences. …”

Land surface temperature changes caused by land cover/land use properties and their impact on rainfall characteristics
Published 2023-07-01“…Image processing analysis was used to analyze the vegetation index, built-up index, and land surface temperature. The mathematical interrelationship between vegetation index, built-up index, land surface temperature, and rainfall intensity was analyzed using linear regression.FINDINGS: The results of the analysis show that the relationship between vegetation index and built-up index is inversely proportional and with land surface temperature is nearly inversely proportional to a coefficient of determination greater than 0.5. …”

First evidence of transovarial transmission of Kyasanur Forest disease virus in Haemaphysalis and Rhipicephalus ticks in the wild
Published 2025-01-01“…Empirical data on pathogen-vector-host interactions and incrimination have not been updated since the last century, despite significant local changes in land use and the expansion of KFD to new areas. Mathematical models predict that transovarial transmission, whereby adult female ticks pass KFDV infections to their offspring, plays an important role in the persistence of KFD, but this has not been shown in the wild. …”
