The Abbaco Tradition (1300-1500): its role in the development of European algebra [PDF]

open access: yes, 2008
Abbaco algebra is a coherent tradition of algebraic problem solving mostly based in the merchant cities of fourteenth and fifteenth-century Italy. This period is roughly situated between two important works dealing with algebra: the Liber Abbaci by ...

On some identities for the DGC Leonardo sequence [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
In this study, we examine the Leonardo sequence with dual-generalized complex (DGC) coefficients for 𝔭∈ℝ. Firstly, we express some summation formulas related to the DGC Fibonacci, DGC Lucas, and DGC Leonardo sequences.

Run-and-tumble particles in speckle fields

open access: yes, 2014
The random energy landscapes developed by speckle fields can be used to confine and manipulate a large number of micro-particles with a single laser beam.

Periodic transmission peak splitting in one dimensional disordered photonic structures

open access: yes, 2016
In the present paper we present ways to modulate the periodic transmission peaks arising in disordered one dimensional photonic structures with hundreds of layers.

Synaesthesia and the creative process: a study of its inspiration in Scriabin’s "Prometheus" [PDF]

open access: yes, 2012
The role of synaesthesia in composition is difficult to assess, but for those who possess it synaesthesia is an inherent source of inspiration. It is not a compositional tool as such, yet synaesthesia is fundamental to the creative and compositional ...

A note on a bivariate Leonardo sequence [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Recently, quite a few generalizations of Leonardo numbers have emerged in the literature. In this short note, we propose a new bivariate extension and provide its generating function.

Towards lightweight integration of SMT solvers [PDF]

open access: yes, 2012
A large variety of SMT techniques and associated solvers have been developed by the formal modelling and verification communities. For a particular application domain, each technique has its own unique set of advantages and limitations.

Chern classes of Schubert cells and varieties

open access: yes, 2006
We give explicit formulas for the Chern-Schwartz-MacPherson classes of all Schubert varieties in the Grassmannian of $d$-planes in a vector space, and conjecture that these classes are effective.

Molecular dynamics simulation study of the high frequency sound waves in the fragile glass former ortho-terphenyl

open access: yes, 2001
Using a realistic flexible molecule model of the fragile glass former orthoterphenyl, we calculate via molecular dynamics simulation the collective dynamic structure factor, recently measured in this system by Inelastic X-ray Scattering.
