The seven-triangle longest-side partition of triangles and mesh quality improvement
(Elsevier, 2008)
A new triangle partition, the seven-triangle longest-edge partition, based on the trisection of the edges is presented and the associated mesh quality improvement property, discussed. The seven-triangle longest-edge ...

High-speed train-induced ground motion and interaction with structures
(Elsevier, 2007)
A general numerical model for the analysis of soil motion due to high-speed train passage and effects on nearby surface and underground structures is presented in this paper. Soil, ballast and structures are represented ...

Bifurcation from zero of a complete trajectory for non-autonomous logistic PDEs
(World Scientific Publishing, 2005-08)
In this paper we extend the well-known bifurcation theory for autonomous logistic equations to the non-autonomous equation ut − ∆u = λu − b(t)u 2 with b(t) ∈ [b0, B0], 0 < b0 < B0 < 2b0. In particular, we prove the ...

Critical-point symmetries in Boson-Fermion systems: The case of shape transitions in odd nuclei in a multiorbit model
(American Physical Review, 2007-02-05)
We investigate phase transitions in boson-fermion systems. We propose an analytically solvable model [E(5/12)] to describe odd nuclei at the critical point in the transition from the spherical to γ-unstable behavior. In ...

Descriptional Complexity of Tissue-Like P Systems with Cell Division
(Springer, 2009)
In this paper we address the problem of describing the complexity of the evolution of a tissue-like P system with cell division. In the computations of such systems the number of (parallel) steps is not sufficient to ...

Ampliación automática de corpus mediante la colaboración de varios etiquetadores
(Sociedad Española para el Procesamiento del Lenguaje Natural (SEPLN), 2006)
La disponibilidad de grandes corpus con texto etiquetado es un aspecto esencial en muchas tareas del procesamiento del lenguaje natural. El esfuerzo que se requiere para etiquetar manualmente este gran número de frases ...

NTRC links built-in thioredoxin to light and sucrose in regulating starch synthesis in chloroplasts and amyloplasts
(2009)
Plants have an unusual plastid-localized NADP-thioredoxin reductase C (NTRC) containing both an NADP-thioredoxin reductase (NTR) and a thioredoxin (Trx) domain in a single polypeptide. Although NTRC is known to supply ...

Influence of spacer layer morphology on the exchange-bias properties of reactively sputtered Co ∕ Ag multilayers
(American Physical Society, 2007-09-25)
We have studied the magnetic properties of [Ag(tAg)/Co(1.2nm)]60 multilayers grown in an oxygen atmosphere. Partial oxidation of the Co layers results in the appearance of tAg dependent exchange-bias properties. A strong ...
