Structural Thermokinetic Modelling

open access: yesMetabolites, 2022
To translate metabolic networks into dynamic models, the Structural Kinetic Modelling framework (SKM) assumes a given reference state and replaces the reaction elasticities in this state by random numbers. A new variant, called Structural Thermokinetic Modelling (STM), accounts for reversible reactions and thermodynamics.

A critical examination of compound stability predictions from machine-learned formation energies [PDF]

open access: yes, 2020
Machine learning has emerged as a novel tool for the efficient prediction of material properties, and claims have been made that machine-learned models for the formation energy of compounds can approach the accuracy of Density Functional Theory (DFT ...

General guidance for custom-built structural equation models [PDF]

open access: yesOne Ecosystem, 2022
Structural Equation Modelling (SEM) represents a quantitative methodology for specifying and evaluating causal network hypotheses. The application of SEM typically involves the use of specialised software packages that implement estimation procedures and

Structural Equation Modeling

open access: yes, 2017
Structural equation modeling (SEM) is a versatile tool for conducting a wide range of multivariate statistical analyses, including multiple regression, mediation analysis, moderation analysis, and analyses of variance and covariance. Two specialized uses of SEM that appear frequently in communication research are confirmatory factor analysis (CFA) and ...

Testing non-nested structural equation models [PDF]

open access: yes, 2015
In this paper, we apply Vuong's (1989) likelihood ratio tests of non-nested models to the comparison of non-nested structural equation models. Similar tests have been previously applied in SEM contexts (especially to mixture models), though the non ...

A preliminary study of the nonlinearity of adhesive point-fixings in structural glass facades

open access: yesJournal of Facade Design and Engineering, 2014
The recent demand for architectural transparency has drastically increased the use of glass material for structural purpose. However, connections between structural glass members represent one of the most critical aspects of glass engineering, due to ...

Efficient Structural Relaxation of Polycrystalline Graphene Models

open access: yesNanomaterials, 2021
Large samples of experimentally produced graphene are polycrystalline. For the study of this material, it helps to have realistic computer samples that are also polycrystalline.

Assessment of strain measurement techniques to characterise mechanical properties of structural steel

open access: yesEngineering Science and Technology, an International Journal, 2014
Strain measurement is important in mechanical testing. A wide variety of techniques exists for measuring strain in the tensile test; namely the strain gauge, extensometer, stress and strain determined by machine crosshead motion, Geometric Moire ...
