LightCUD: a program for diagnosing IBD based on human gut microbiome data
BioData Mining, 2021 Background The diagnosis of inflammatory bowel disease (IBD) and discrimination between the types of IBD are clinically important. IBD is associated with marked changes in the intestinal microbiota. Advances in next-generation sequencing (NGS) technology

Aerodynamic generation of electric fields in turbulence laden with charged inertial particles
Nature Communications, 2018 How lightning occurs in dusty atmospheres remains largely unknown because of the complexity of the turbulent flows involved. Di Renzo and Urzay reveal a flow-driven mechanism of charge separation by simulating turbulence laden with hundreds of millions ...

Fluids, 2023 This paper addresses one of the major obstacles arising in the high-fidelity scale-resolving simulations of turbulent flows inside ducts with the walls covered by acoustic liners in order to attenuate the sound radiated from the duct.

Journal of Fluid Mechanics, 2017 In this paper, we address the problem of how to account for second-order statistics of turbulent flows using low-complexity stochastic dynamical models based on the linearized Navier–Stokes equations. The complexity is quantified by the number of degrees of freedom in the linearized evolution model that are directly influenced by stochastic excitation ...

Unified energy law for fluctuating density wave orders in cuprate pseudogap phase
Communications Physics, 2022 The origin of the pseudogap in the cuprates and how it is related to the mechanism of their superconductivity has been a topic of long standing debate. Here, the authors suggest that the pseudogap is governed by a unified energy law the basis for which ...

Criteria of tracking vortex surfaces in turbulent-like flows
Advances in Aerodynamics, 2022 We propose criteria of tracking vortex surfaces in complex flows based on the vortex-surface field (VSF). The criteria characterize the accuracy and Lagrangian tracking performance of the numerical VSF solution, and determine the time period when the ...

Turbulent thermal diffusion in a multi-fan turbulence generator with the imposed mean temperature gradient [PDF]
Experiments in Fluids, 2006, v. 40, 744-752, 2006 We studied experimentally the effect of turbulent thermal diffusion in a multi-fan turbulence generator which produces a nearly homogeneous and isotropic flow with a small mean velocity. Using Particle Image Velocimetry and Image Processing techniques we showed that in a turbulent flow with an imposed mean vertical temperature gradient (stably ...
