A Mathematically Exact and Well-Determined System of Equations to Close Reynolds-Averaged Navier–Stokes Equations

open access: yesMathematics, 2023
Since Sir Osborne Reynolds presented the Reynolds-averaged Navier–Stokes (RANS) equations in 1895, the construction of complete closure for RANS equations has been regarded as extremely challenging.

Peptide Sequencing With Single Acid Resolution Using a Sub‐Nanometer Diameter Pore

open access: yesAdvanced Functional Materials, EarlyView.
To sequence a single molecule of Aβ1−42–sodium dodecyl sulfate (SDS), the aggregate is forced through a sub‐nanopore 0.4 nm in diameter spanning a 4.0 nm thick membrane. The figure is a visual molecular dynamics (VMD) snapshot depicting the translocation of Aβ1−42–SDS through the pore; only the peptide, the SDS, the Na+ (yellow/green) and Cl− (cyan ...

Analysis of a mathematical model related to Czochralski crystal growth

open access: yesAbstract and Applied Analysis, 1998
This paper is devoted to the study of a stationary problem consisting of the Boussinesq approximation of the Navier–Stokes equations and two convection–diffusion equations for the temperature and concentration, respectively.

On the accuracy of difference scheme for Navier-Stokes equations

open access: yesVestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2014
The article presents a study of difference schemes in time, which accuracy can be arbitrarily high. We present difference schemes in time for solving the Navier-Stokes equations, where series expansions are used to find the singularities of solutions of ...

Geometry‐Guided Osteogenesis in Bone‐on‐a‐Chip Systems Using Triply Periodic Minimal Surface Scaffolds

open access: yesAdvanced Healthcare Materials, EarlyView.
This study presents a bone‐on‐a‐chip platform incorporating TPMS scaffolds to study geometry‐dependent osteogenesis under dynamic flow. By tuning pore shape and solidity, it precisely controls mechanical cues, revealing how topological features and shear stress affect osteogenic differentiation and matrix formation.

Self-Similar Solutions with Elliptic Symmetry for the Compressible Euler and Navier-Stokes Equations in R^{N}

open access: yes, 2011
Based on Makino's solutions with radially symmetry, we extend the corresponding ones with elliptic symmetry for the compressible Euler and Navier-Stokes equations in R^{N} (N\geq2).

Leveraging Transfer Learning to Overcome Data Limitations in Czochralski Crystal Growth

open access: yesAdvanced Theory and Simulations, EarlyView.
A data‐driven framework combining Computational Fluid Dynamics (CFD) simulations and machine learning is proposed to model and optimize Czochralski crystal growth. Using different transfer learning strategies (Warm Start, Merged Training, and Hyperparameter Transfer) the study demonstrates improved predictions for Ge and GaAs growth from Si‐trained ...

One‐Step Assembly of α‐Aryl‐Substituted DOTAs as Superior and Universal Platforms for Multifunctional Theranostics

open access: yesAngewandte Chemie, EarlyView.
A one‐step multi‐component synthetic approach is reported to construct α‐aryl‐substituted DOTAs, which required tedious multi‐step synthesis in all previous works. The synthesized α‐aryl‐substituted DOTAs showed improved performance for developing multifunctional theranostics and represent a universal platform for bioconjugation. Abstract α‐Substituted
