A rational method for determining intermittency in the transitional boundary layer [PDF]

, 2019
A new rational procedure is proposed for determining the intermittency in the streamwise direction. One of the key parameters for the intermittency determination is the selection of a threshold value, which often involves a certain level of subjectivity.

On the Plants Leaves Boundary, "Jupe \`a Godets" and Conformal Embeddings

, 2001
The stable profile of the boundary of a plant's leaf fluctuating in the direction transversal to the leaf's surface is described in the framework of a model called a "surface \`a godets".

Clustering of floaters on the free surface of a turbulent flow: an experimental study [PDF]

, 2016
We present an experimental study of the statistical properties of millimeter-size spheres floating on the surface of a turbulent flow. The flow is generated in a layer of liquid metal by an electromagnetic forcing. By using two magnet arrays, we are able

An Infinite-Dimensional Family of Black-Hole Microstate Geometries [PDF]

, 2010
We construct the first explicit, smooth, horizonless black-hole microstate geometry whose moduli space is described by an arbitrary function of one variable and is thus infinite-dimensional. This is achieved by constructing the scalar Green function on a

Receptivity to Freestream Periodic Vorticity Disturbance on a Flat Plate with an Elliptic Leading Edge

Journal of Applied Fluid Mechanics, 2020
The receptivity of the Blasius boundary layer over a semi-infinite flat plate with an elliptic leading edge and of aspect ratio five was investigated using a direct numerical solution of two-dimensional Navier-Stokes equations. The result of the computation

Controlling light emission from semiconductor nanoplatelets using surface chemistry

Nature Communications
Semiconductor nanoplatelets are atomically flat nanocrystals which emit light with high spectral purity at wavelengths controlled by their thickness. Despite their technological potential, efforts to further sharpen the emission lines of nanoplatelets ...

Preheating in an Expanding Universe: Analytic Results for the Massless Case [PDF]

, 1997
Analytic results are presented for preheating in both flat and open models of chaotic inflation, for the case of massless inflaton decay into further inflaton quanta.

Effect of Thermal Undulations on the Bending Elasticity and Spontaneous Curvature of Fluid Membranes

, 2000
We amplify previous arguments why mean curvature should be used as measure of integration in calculating the effective bending rigidity of fluid membranes subjected to a weak background curvature.
