MetaComp: comprehensive analysis software for comparative meta-omics including comparative metagenomics

BMC Bioinformatics, 2017
Background During the past decade, the development of high throughput nucleic sequencing and mass spectrometry analysis techniques have enabled the characterization of microbial communities through metagenomics, metatranscriptomics, metaproteomics and ...

Deep learning fluid flow reconstruction around arbitrary two-dimensional objects from sparse sensors using conformal mappings

AIP Advances, 2022
The usage of neural networks (NNs) for flow reconstruction (FR) tasks from a limited number of sensors is attracting strong research interest owing to NNs’ ability to replicate high-dimensional relationships.

POD Analysis of the Wake of Two Tandem Square Cylinders

Fluids
This study aims to investigate the wake of two tandem square cylinders based on the Proper Orthogonal Decomposition (POD) analyses of the PIV and hotwire data. The cylinder centre-to-centre spacing ratio L/w examined is from 1.2 to 4.2, covering the four

Investigating the Linear Dynamics of the Near-Field of a Turbulent High-Speed Jet Using Dual-Particle Image Velocimetry (PIV) and Dynamic Mode Decomposition (DMD)

Fluids, 2023
The quest for the physical mechanisms underlying turbulent high-speed jet flows is underpinned by the extraction of spatio-temporal coherent structures from their flow fields.

Turbulence Intensity Scaling: A Fugue

, 2019
We study streamwise turbulence intensity definitions using smooth- and rough-wall pipe flow measurements made in the Princeton Superpipe. Scaling of turbulence intensity with the bulk (and friction) Reynolds number is provided for the definitions.

Archimedes’ law explains penetration of solids into granular media

Nature Communications, 2018
The penetration dynamics of solid objects into granular media has been described by theories that are constrained to the use of phenomenological models or empirical parameters. Here, Kang et al.

Towards a Simple Model of Compressible Alfvenic Turbulence [PDF]

, 1997
A simple model collisionless, dissipative, compressible MHD (Alfvenic) turbulence in a magnetized system is investigated. In contrast to more familiar paradigms of turbulence, dissipation arises from Landau damping, enters via nonlinearity, and is ...

A symmetry-based length model for characterizing the hypersonic boundary layer transition on a slender cone at moderate incidence

Advances in Aerodynamics, 2022
The hypersonic boundary layer (HBL) transition on a slender cone at moderate incidence is studied via a symmetry-based length model: the SED-SL model. The SED-SL specifies an analytic stress length function (which defines the eddy viscosity) describing a

The Nature of Subproton Scale Turbulence in the Solar Wind

, 2013
The nature of subproton scale fluctuations in the solar wind is an open question, partly because two similar types of electromagnetic turbulence can occur: kinetic Alfven turbulence and whistler turbulence.
