Factors Governing the Chemical Stability and NMR Parameters of Uracil Tautomers and Its 5-Halogen Derivatives

open access: yesMolecules, 2020
We report on the density functional theory (DFT) modelling of structural, energetic and NMR parameters of uracil and its derivatives (5-halogenouracil (5XU), X = F, Cl, Br and I) in vacuum and in water using the polarizable continuum model (PCM) and the ...

Advanced physical modeling of SiOx resistive random access memories [PDF]

open access: yes, 2016
We apply a three-dimensional (3D) physical simulator, coupling self-consistently stochastic kinetic Monte Carlo descriptions of ion and electron transport, to investigate switching in silicon-rich silica (SiOx) redox-based resistive random-access memory (

Design and Manufacturing of Small Scale Tsunami Simulator Channel [PDF]

open access: yesE3S Web of Conferences, 2021
Increasing the cost of in-situ or field tests to solve engineering problems, particularly water engineering, pushes researchers worldwide to simulate different water engineering problems using small-scale physical modeling like soil erosion, hydraulic ...

Multiple outbreaks for the same pandemic: Local transportation and social distancing explain the different 'waves' of A-H1N1pdm cases observed in México during 2009

open access: yesMathematical Biosciences and Engineering, 2010
Influenza outbreaks have been of relatively limited historical interest in México. The 2009 influenza pandemic not only changed México's health priorities but also brought to the forefront some of the strengths and weaknesses of México's ...

Assessing the Mass Transfer Coefficient in Jet Bioreactors with Classical Computer Vision Methods and Neural Networks Algorithms

open access: yesAlgorithms, 2023
Development of energy-efficient and high-performance bioreactors requires progress in methods for assessing the key parameters of the biosynthesis process. With a wide variety of approaches and methods for determining the phase contact area in gas–liquid

Models in physics [PDF]

open access: yes, 2018
In its most common use, the term ‘model’ refers to a simplified and stylised version of the so-called target system, the part or aspect of the world that we are interested in. For instance, in order to determine the orbit of a planet moving around the sun we model the planet and the sun as perfect homogenous spheres that gravitationally interact with ...

Expressing Measurement Uncertainty in OCL/UML Datatypes [PDF]

open access: yes, 2018
Uncertainty is an inherent property of any measure or estimation performed in any physical setting, and therefore it needs to be considered when modeling systems that manage real data.

Exploring the phase stability in interpenetrated diamondoid covalent organic frameworks

open access: yesCommunications Chemistry, 2023
While stimuli-responsive metal-organic frameworks have been widely investigated, much less is understood about structural flexibility in their covalent counterparts.
