Prediction of Retention Indices and Response Factors of Oxygenates for GC-FID by Multilinear Regression

open access: yesData, 2022
The replacement of fossil carbon sources with green bio-oils promotes the importance of several hundred oxygenated hydrocarbons, which substantially increases the analytical effort in catalysis research. A multilinear regression is performed to correlate retention indices (RIs) and response factors (RFs) with structural properties. The model includes a

Experimental and design‐oriented research on fiber reinforced concrete segmental tunnel linings: A systematic review

open access: yesStructural Concrete, EarlyView.
Abstract The use of fiber reinforced concrete (FRC) in precast tunnel segments is among the most established and representative applications of this material. Over the past two decades, numerous tunnel linings were constructed with partial or total substitution of conventional steel reinforcement by fibers, this yielding to quantifiable benefits in ...

Taking Stock: Elite Studies and Social Change

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT This article provides a systematic synthesis of contemporary elite sociology through the analytical lens of change and stability. We distinguish between two types of change: change within elites, referring to transformations in elite composition, circulation, or internal characteristics; and change by elites, designating processes whereby ...

Enhancing Rock Strength Prediction and Features Selection by Coupling Well Log Data and Deep Learning Approaches in Reservoir Geomechanics

open access: yesInternational Journal for Numerical and Analytical Methods in Geomechanics, Volume 50, Issue 11, Page 4724-4738, 10 August 2026.
ABSTRACT Accurate rock strength parameters play a vital role in petroleum and mining operations for sustainable drilling activities, and wellbore stability analysis. This study investigates the applicability of deep learning techniques for assessing data‐driven models, and to conduct parametric sensitivity examination for feature attributes ranking to ...

A Reconciled Satellite Record Reveals a Negative Low Cloud Feedback Over the Past 47 Years

open access: yesGeophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Low‐cloud feedback continues to dominate uncertainty in climate sensitivity, with no direct observational estimate to date. Here we provide the first such estimate by combining satellite and reanalysis data sets within a cloud‐controlling factor (CCF) framework.
