On the Non-Progressive Spread of Influence through Social Networks
MohammadAmin Fazli, Mohammad Ghodsi, Jafar Habibi +3
The spread of influence in social networks is studied in two main categories: the progressive model and the non-progressive model (see e.g. the seminal work of Kempe, Kleinberg, an…
Fractal structure of a three dimensional Brownian motion on an attractive plane
Abbas Ali Saberi
Consider a Brownian particle in three dimensions which is attracted by a plane with a strength proportional to some dimensionless parameter . We investigate the fractal spatial…
On additive and multiplicative arithmetical functions
Masood Aryapoor
A characterization of multiplicative (and additive) arithmetical functions is given. Using this characterization, we show that the group of multiplicative arithmetical functions is…
Vehicular traffic flow at an intersection with the possibility of turning
M. Ebrahim Foulaadvand, Somayyeh Belbasi
We have developed a Nagel-Schreckenberg cellular automata model for describing of vehicular traffic flow at a single intersection. A set of traffic lights operating in fixed-time s…
Physical conditions of the interstellar medium of high-redshift, strongly lensed submillimetre galaxies from the Herschel-ATLAS
Ivan Valtchanov, J. Virdee, R. J. Ivison +51
We present Herschel-SPIRE Fourier Transform Spectrometer (FTS) and radio follow-up observations of two Herschel-ATLAS (H-ATLAS) detected strongly lensed distant galaxies. In one of…
Effect of hydrogen adsorption on the quasiparticle spectra of graphene
M. Farjam, D. Haberer, A. Grüneis
We use the non-interacting tight-binding model to study the effect of isolated hydrogen adsorbates on the quasiparticle spectra of single-layer graphene. Using the Green's function…
