The origins of Zipf's meaning-frequency law
Ramon Ferrer-i-Cancho, Michael S. Vitevitch
In his pioneering research, G. K. Zipf observed that more frequent words tend to have more meanings, and showed that the number of meanings of a word grows as the square root of it…
Three-dimensional simulations of the interaction between the nova ejecta, the accretion disk, and the companion star
Joana Figueira, Jordi Jose, Enrique Garcia-Berro +3
Context. Classical novae are thermonuclear explosions hosted by accreting white dwarfs in stellar binary systems. Material piles up on top of the white dwarf star under mildly dege…
Self-induced Faraday instability laser
A. M. Perego, S. V. Smirnov, K. Staliunas +2
We predict the onset of self-induced parametric or Faraday instabilities in a laser, spontaneously induced by the presence of pump depletion in the cavity, which leads to a periodi…
A face-centred finite volume method for second-order elliptic problems
Ruben Sevilla, Matteo Giacomini, Antonio Huerta
This work proposes a novel finite volume paradigm, the face-centred finite volume (FCFV) method. Contrary to the popular vertex (VCFV) and cell (CCFV) centred finite volume methods…
A slip-based model for the size-dependent effective thermal conductivity of nanowires
M. Calvo-Schwarzwälder, M. G. Hennessy, P. Torres +2
The heat flux across a nanowire is computed based on the Guyer-Krumhansl equation. Slip conditions with a slip length depending on both temperature and nanowire radius are introduc…
Open Orchestration Cloud Radio Access Network (OOCRAN) Testbed
Marti Floriach-Pigem, Guillem Xercavins-Torregrosa, Vuk Marojevic +1
The Cloud radio access network (C-RAN) offers a revolutionary approach to cellular network deployment, management and evolution. Advances in software-defined radio (SDR) and networ…
