Na+/Cl-/creatine transporter activity and expression in rat brain synaptosomes
(Elsevier, 2010)
Creatine is involved in brain ATP homeostasis and it may also act as neurotransmitter. Creatine transport was measured in synaptosomes obtained from the diencephalon and telencephalon of suckling and 2 month-old rats. ...

Existence and uniqueness of positive large solutions to some cooperative elliptic systems
(De Gruyter, 2003-05)
In this work we consider positive solutions to cooperative elliptic systems of the form −∆u = λu−u2 +buv, −∆v = µv −v2 +cuv in a bounded smooth domain Ω ⊂ RN (λ, µ ∈ R, b, c > 0) which blow up on the boundary ∂Ω, that is ...

Robust facility location
(Springer, 2003-11)
Let A be a nonempty finite subset of the plane representing the geographical coordinates of a set of demand points (towns, …), to be served by a facility, whose location within a given region S is sought. Assuming that the ...

Granular avalanches: Deterministic, correlated and decorrelated dynamics
(IOP Publishing Ltd., 2004-12-15)
A statistical analysis of granular avalanches in a half-filled and slowly rotated drum is presented. For large-sized grains the classical coherent oscillation is reproduced, i.e. we observe a quasi-periodic succession of ...

A Controlled Experiment for Evaluating a Metric–Based Reading Technique for Requirements Inspection
(IEEE Computer Society, 2004)
Natural language requirements documents are often verified by means of some reading technique. Some recommendations for defining a good reading technique point out that a concrete technique must not only be suitable for ...

Modulation of the input–output function by GABAA receptor-mediated currents in rat oculomotor nucleus motoneurons
(Physiological Society, 2014)
The neuronal input–output function depends on recruitment threshold and gain of the firing frequency–current (f–I) relationship. These two parameters are positively correlated in ocular motoneurons (MNs) recorded in alert ...

Implementing in Prolog an Effective Cellular Solution to the Knapsack Problem
(Springer, 2004)
In this paper we present an implementation in Prolog of an effective solution to the Knapsack problem via a family of deterministic P systems with active membranes using 2-division.
