PURPOSE To analyze the effect of prolonged (daily) electrical vagus nerve stimulation (VNS) on daily amygdaloid kindling (AK) in freely moving cats. METHODS Fifteen adult male cats were implanted in both temporal lobe amygdalae, both lateral geniculate bodies, and prefrontal cortices. A bipolar hook (5-mm separation) stainless steel electrode also was(More)
Lattice gas and lattice Boltzmann methods are recently developed numerical schemes for simulating a variety of physical systems. In this paper a new lattice Boltzmann model for modeling two-dimensional incompressible magnetohydrodynam-ics (MHD) is presented. The current model fully utilizes the flexibility of the lattice Boltzmann method in comparison with(More)
In this paper we show that some important geometric modelling and geometric optimization problems related to implicitly defined algebraic plane curves, such as locating the singular points, the points of characteristic curvature, as well as computing the Eu-clidean distance from a point to a curve and computing the maxi-mal/minimal distance between two(More)
This paper describes a conceptual framework for facilitating the modelling and development of heuristic reasoning services in clinical domains. The purpose of this framework is to provide support for 1) the representation of medical knowledge in a structured manner, 2) the design of clinical tasks such as diagnosis, therapy planning and patient monitoring,(More)
Indorenate (TR3369, 5-methoxytryptamine b-methylcarboxylate HCl) is a 5-HT1-like receptor agonist with hypotensive activity. Here, we describe that indorenate also decreases food intake (ED50 26.1 mg/kg) without an appreciable effect in water intake (the estimated ED50 for water was 589.8 mg/kg). The anorectic activity of indorenate was compared to the(More)

This discussion paper is/has been under review for the journal Atmospheric Chemistry and Physics (ACP). Please refer to the corresponding final paper in ACP if available. Abstract Observations of Lifted Temperature Minimum (LTM) profiles in the nocturnal boundary layer were first reported by Ramdas and Atmanathan (1932). It was defined by the existence of a(More)
We propose a novel detection concept for neutrinoless double-beta decay searches. This concept is based on a Time Projection Chamber (TPC) filled with high-pressure gaseous xenon, and with separated-function capabilities for calorimetry and tracking. Thanks to its excellent energy resolution, together with its powerful background rejection provided by the(More)
We show in a systematic and clear way how factorization methods can be used to construct the generators for hidden and dynamical symmetries. This is shown by studying the 2D problems of hydrogen atom, the isotropic harmonic oscillator and the radial potential Aρ 2ζ−2 − Bρ ζ−2. We show that in these cases the non-compact (compact) algebra corresponds to(More)

Resumen—En este artículo se presentan los resultados obtenidos, al emplear algoritmos genéticos para la combinación de algunas técnicas y clasificadores utilizados en el reconocimiento de rostros con imágenes infrarrojas. Se muestra que bajo el esquema de combinación propuesto, el sistema presenta un mayor desempeño que las técnicas individuales y abre un(More)
