A Spatial Correlation Identification Model for Coherent Structure Extraction and Three-Dimensional Visualization

open access: yesJournal of Marine Science and Engineering
Multi-scale coherent structures have been observed in ocean currents, which are induced by the interaction of shear flows with different velocities. Understanding the spatial configuration and scale characteristics of coherent structures will promote the

Numerical Simulation of Coherent Structures in the Turbulent Boundary Layer under Different Stability Conditions

open access: yesEnergies, 2020
Coherent structures in the turbulent boundary layer were investigated under different stability conditions. Qualitative analyses of the flow field, spatial correlation coefficient field and pre-multiplied wind velocity spectrum showed that the dominant ...

Enriched homotopy-coherent structures [PDF]

open access: yes, 2023
We introduce a general notion of enrichment for homotopy-coherent algebraic structures described by Segal conditions, using the framework of "algebraic patterns" developed in our previous work. This recovers several known examples of enriched structures,

Large eddy simulation of film cooling on turbine vane

open access: yesJournal of Thermal Science and Technology, 2019
Large eddy simulations were performed for film cooling on scaled-up C3X turbine vane at the nominal blowing ratio of M=0.5~1.5, and the Reynolds number, Re=3000, based on the mainstream inlet velocity and hole diameter.

LAGRANGIAN COHERENT STRUCTURES IN NONLINEAR DYNAMOS [PDF]

open access: yesThe Astrophysical Journal, 2011
Turbulence and chaos play a fundamental role in stellar convective zones through the transportof particles, energy and momentum, and in fast dynamos, through the stretching, twisting and folding of magnetic flux tubes. A particularly revealing way to describe turbulent motions is through the analysis of Lagrangian coherent structures (LCS), which are ...

COMPRESSIVE COHERENT STRUCTURES AT ION SCALES IN THE SLOW SOLAR WIND [PDF]

open access: yes, 2016
We present a study of magnetic field fluctuations in a slow solar wind stream, close to ion scales, where an increase of the level of magnetic compressibility is observed. Here, the nature of these compressive fluctuations is found to be characterized by

The microbiome in human skin aging

open access: yesFEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.

Large eddy simulations of methane oxidation at ultra-wet conditions in a model gas turbine combustor applying detailed chemistry

open access: yesJournal of Fluid Science and Technology, 2014
The addition of steam to the combustion process is a promising avenue, in order to reduce harmful emissions and simultaneously increase the efficiency. In contrast to traditional flames where the heat release exhibits a thin flame front, operating under ...

From junk to function — How weak selection in eukaryotes builds new parts and drives genomic complexity

open access: yesFEBS Letters, EarlyView.
How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...
