Using microelectrode models for real time cell-culture monitoring

This paper proposes a cell-microelectrode model for cell biometry applications, based on the area overlap as main parameter. The model can be applied to cell size identification, cell count, and their extension to cell growth and dosimetry protocols. Experiments performed with comercial electrodes are presented, illustrating a procedure to obtain cell number in both growth and dosimetry processes. Results obtained for the AA8 cell line are promising.Junta de Andalucía P0-TIC-538

Sobre Tibulo 1, 6, 51-53

Este trabajo analiza en detalle un posible juego de palabras en el v. 53 attigerit. Junto a un obvio sentido sexual, el verbo tiene también una acepción jurídica (= ‘tocar para robar’) ajustada al contexto global del poema, que trata de la custodia puellae y del furtum amoris.This article analyzes in detail a possible pun on v. 53 attigerit. Together with an obvious sexual meaning, that verb has also juridical overtones (=’lay hands upon in order to steal’) that fit the context of the whole poem, which deals with custodia puellae and furtum amoris

"Lyde ludens" (Hor. "Carm". 3.11.8-10): avatares y azares de un juego de palabras

This paper deals with the word-play Lyde ~ ludit at HOR.Carm.3.11-8-10 and its linguistic and cultural background (§ 1); it also conjectures the symbolic meaning of the pun, while reflecting on its relevance for the discussion on the relationship between Carm.2.11.21-24, 3.11 and 3.28 as items of a poetic cycle (§ 2); in connection to this, attention is given to Horace’s farewell to the game of love and lyric poetry (§ 3); some possible echoes of Horace’s word-play in later literature are also considered (§ 4).Temas de este articulo son el juego verbal Lyde ~ ludit en HOR.Carm.3.11.8-10 y su trasfondo linguistico (§ 1); la posible relevancia de ese juego verbal y de su presumible simbolismo para la consideración de Carm.2.11.21-24, 3.11 y 3.28 como ciclo poetico (§ 2); la despedida horaciana del ludus lirico-amoroso en Epístolas y Odas 4 (§ 3); posibles repercusiones del juego verbal Lyde ~ ludit en la tradicion literaria posterior (§ 4)

Ausonio, Par. praef. uers. 15-18 y Marcial VI 28.10

In the first section of this paper, the interpretations of Ausonius’ passage by Green (1991) and Lolli (1997) are subjected to criticism; the traditional view on praeter iustum is reinforced, and further linguistic and poetic aspects of this expression are explored. In the second section, it is investigated how alternative approaches to Ausonius’ locus, such as that of Green or Barth’s attempted emendation of iustum > nostrum (1624), are consequential to the comparison of Par. praef. uers. 18 with Martial’s VI 28.10 as printed by all editors (qui fles talia, nil fleas uiator); it is then argued that the traditional text and interpretation of Ausonius’ line and a revised text of Martial (either qui fles, talia nil fleas, uiator, as punctuated by Salanitro, or qui fles, tale nihil fleas, uiator, as I have suggested elsewhere) are mutually consistent and provide philological support for each other (§§ 2-3).En la primera sección de este trabajo se someten a crítica las interpretaciones del pasaje de Ausonio propuestas por Green (1991) y Lolli (1997) y se refuerza la interpretación tradicional de praeter iustum, al tiempo que se analizan otros aspectos de esta expresión. En § 2 se investiga cómo lecturas alternativas del pasaje de Ausonio, como la defendida por Green o la conjetura de Barth a iustum (codd.) > nostrum (1624), son consecuentes con el cotejo de Mart. VI 28.10, paralelo citado por esos estudiosos según el texto de todas las ediciones antiguas y modernas (qui fles talia, nil fleas, uiator). Se razona que el texto e interpretación tradicionales de Ausonio y un texto repuntuado de Marcial (qui fles, talia nil fleas, uiator, según propuesta de Salanitro, 1996 / qui fles, tale nihil fleas uiator, según propuesta propia) son mutuamente coherentes y se prestan apoyo filológico recíproco (§§ 2-3)

On Martial, 1 "praef".1-3

Defensa e interpretación de scribat enMART.1 praef. 3, basada en una explicación en parte nueva de improbe... est, que elabora y desarrolla observaciones al pasaje realizadas, principalmente, por los comentaristas de la edición de Lemaire (1825), Citroni (1975) y Fitzgerald (2007). Junto a ello, se exploran las implicaciones jurídicas de ingeniosus in alieno libro esse, con atención a las reminiscencias del lenguaje legal en improbe facit. Se concluye, así, que el malignus interpres puede ser visto desde la perspectiva de Marcial como difamador epigramático, y la frase nec epigrammata mea scribat, lejos de necesitar enmienda, debería ser leída como una deliberada paradoja que anticipa brillantemente modernas teorías sobre el papel del lector en la creación de significado.This article offers a defense and interpretation of scribat in Mart. 1.praef.3, based on a partially new explanation of improbe...est. The argument elaborates on observations made mainly by the commentators of the Lemaire edition (1825), Citroni (1975) and Fitzgerald (2007). The juridical implications of ingeniosus in libro alieno esse are also explored with particular attention to hitherto unnoticed legal overtones in improbe facit. It is thus concluded that the malignus interpres can be viewed, fromMartial’s perspective, as deserving the punishment of censorship for libel-writing; and at the same time, nec epigrammata mea scribat, far from needing textual emendation, should be read as a deliberate paradox which brilliantly prefigures modern theories about the role of readers in the creation of meaning

Efficient integral equation formulation for inductive waveguide components with posts touching the waveguide walls

In this paper a surface integral equation technique is employed for the analysis of inductive waveguide problems containing metallic or dielectric objects of arbitrary shape, focusing on the case where these objects are connected to the waveguide walls. Using the extinction theorem, the main problem is split into two problems. In the first one the parallel plate waveguide Green’s functions are used. Because of the choice of these functions, the side of the object touching the waveguide wall is not considered for discretization in a method of moments analysis. The second problem is applied inside the dielectric object, and uses the free space Green’s functions. It is shown that an additional spatial image is needed to impose the proper boundary conditions for the fields on the side touching the waveguide wall in the original problem. Results show the importance of including this additional image in the formulation for the correct behavior of the fields. With the proposed technique, the paper explores some alternatives for designing specific filter responses using dielectric posts inside cavity filters. Comparisons with a commercial finite elements tool demonstrate the accuracy of the proposed integral equation formulation.This work has been developed with support from the Spanish National Project (CICYT) with Ref TEC2004-04313-C02-02/TCM, and the Regional Seneca Project with Ref 02972/PI/05

A new neural network technique for the design of multilayered microwave shielded bandpass filters

In this work, we propose a novel technique based on neural networks, for the design of microwave filters in shielded printed technology. The technique uses radial basis function neural networks to represent the non linear relations between the quality factors and coupling coefficients, with the geometrical dimensions of the resonators. The radial basis function neural networks are employed for the first time in the design task of shielded printed filters, and permit a fast and precise operation with only a limited set of training data. Thanks to a new cascade configuration, a set of two neural networks provide the dimensions of the complete filter in a fast and accurate way. To improve the calculation of the geometrical dimensions, the neural networks can take as inputs both electrical parameters and physical dimensions computed by other neural networks. The neural network technique is combined with gradient based optimization methods to further improve the response of the filters. Results are presented to demonstrate the usefulness of the proposed technique for the design of practical microwave printed coupled line and hairpin filters
