Coulomb Drag and Magnetotransport in Graphene Double Layers

, 2012
We review the fabrication and key transport properties of graphene double layers, consisting of two graphene monolayers placed in close proximity, independently contacted, and separated by an ultra-thin dielectric.

Numerical Study of Irregularly Roughened Micro-Particles’ Drag in Laminar Flow

Applied Sciences
The effect of surface roughness in laminar flow has been the focus of recent research related to drag reduction. However, although particle transport is governed by laminar flow in most applications, the effect of surface texture on the drag of a sphere ...

Dragging Bistable Fronts

Physica Scripta, 2004
Summary: We consider the dragging of fronts in reaction--diffusion systems with bistable nonlinearity by an external drive, which may be parametric or direct. A perturbation theory is developed for the speed correction of the dragged front. The predictions are found to be in good agreement with direct simulations, apart from an initial transient. While

Pomiędzy queerową subwersją a „middle-class mainstreaming”. O twórczości drag queen Mony Lizak

Literatura i Kultura Popularna
This article is a critical reflection on the stage and musical work of drag queen Mona Lizak. The author asks about the form (stage style) and content (ideological message) of the artist’s con­ceptual and speculative works and its connections with the ...

Coulomb drag as a signature of the paired quantum Hall state

, 1999
Motivated by the recent Coulomb drag experiment of M. P. Lilly et. al, we study the Coulomb drag in a two-layer system with Landau level filling factor $\nu=1/2$.

Recreating Observed Convection‐Generated Gravity Waves From Weather Radar Observations via a Neural Network and a Dynamical Atmospheric Model

Journal of Advances in Modeling Earth Systems
Convection‐generated gravity waves (CGWs) transport momentum and energy, and this momentum is a dominant driver of global features of Earth's atmosphere's general circulation (e.g., the quasi‐biennial oscillation, the pole‐to‐pole mesospheric circulation)

Physical Modelling of Blue Mussel Dropper Lines for the Development of Surrogates and Hydrodynamic Coefficients

Journal of Marine Science and Engineering, 2019
In this work, laboratory tests with live bivalves as well as the conceptual design of additively manufactured surrogate models are presented. The overall task of this work is to develop a surrogate best fitting to the live mussels tested in accordance to

Superfluid drag in the two-component Bose-Hubbard model

, 2018
In multicomponent superfluids and superconductors, co- and counter-flows of components have in general different properties. It was discussed in 1975 by Andreev and Bashkin, in the context of He$^3$/He$^4$ superfluid mixtures, that inter-particle ...

Improved Design for Horizontal Axis Wind Turbine Blades with Winglets

Platform, a Journal of Engineering, 2023
The horizontal axis wind turbine blades are modified to enhance the turbine's aerodynamic performance. The performance of the modified geometry was evaluated by comparing the lift, drag and torque findings to the same propeller with a
