Internal bores and gravity currents in a two-fluid system [PDF]

, 2014
In this paper, a unified theory of internal bores and gravity currents is presented within the framework of the one-dimensional two-layer shallow-water equations. The equations represent four basic physical laws: the theory is developed on the basis of

Dynamical Origin of Extrasolar Planet Eccentricity Distribution

, 2008
We explore the possibility that the observed eccentricity distribution of extrasolar planets arose through planet-planet interactions, after the initial stage of planet formation was complete.

Quantum transport through mesoscopic disordered interfaces, junctions, and multilayers

, 2001
The study explores perpendicular transport through macroscopically inhomogeneous three-dimensional disordered conductors using mesoscopic methods (real-space Green function technique in a two-probe measuring geometry). The nanoscale samples (containing $\

UHECR as Decay Products of Heavy Relics? The Lifetime Problem

, 2002
The essential features underlying the top-down scenarii for UHECR are discussed, namely, the stability (or lifetime) imposed to the heavy objects (particles) whatever they be: topological and non-topological solitons, X-particles, cosmic defects ...

Biswapped Networks and Their Maximal Twin-Preserving Subgraphs With a Motivation on Connection Number in Network-Based Approaches

IEEE Access
The use of optoelectronic technology in Optical Transposition Interconnection Systems (OTIS) offers an effective solution to the ongoing problem of storing and sending data with comprehensive information. This is due to the reduced power requirements and

On the Goedel's formula

, 2008
This article examines the formula G (of Goedel). We demonstrated that the Goedel's number of the formula G is not a finite number if (i) G is comprehended as a self-referential statement or (ii) there is an infinite set S of well-formed formulae such ...

A Labelled Sequent Calculus for BBI: Proof Theory and Proof Search

, 2015
We present a labelled sequent calculus for Boolean BI, a classical variant of O'Hearn and Pym's logic of Bunched Implication. The calculus is simple, sound, complete, and enjoys cut-elimination.
