Del simbolisme eròtic de la imatge del cavall

In this paper the author analyses some passages from the Greek literature, earlier than the hellenistic epigramm, where there appears some horse images with an erotic interpretation which are the starting point to study the transmition of the elements from these images throught tradition

Autism 70 years after Leo Kanner and Hans Asperger

A partir de las aportaciones de Leo Kanner (1943) y Hans Asperger (1944), el autismo ha sido foco de intenso debate, no sólo sobre aspectos fenomenológicos, etiológicos y terapéuticos;sino también sobre su propia naturaleza. La presente revisión pretende situar el autismo como un concepto dinámico sometido a interpretaciones no solo diversas, sino radicalmente enfrentadas

El autismo 70 años después de Leo Kanner y Hans Asperger.

A partir de las aportaciones de Leo Kanner (1943) y Hans Asperger (1944), el autismo ha sido foco de intenso debate, no sólo sobre aspectos fenomenológicos, etiológicos y terapéuticos; sino también sobre su propia naturaleza. La presente revisión pretende situar el autismo como un concepto dinámico sometido a interpretaciones no solo diversas, sino radicalmente enfrentadas. Bajo un controvertido debate entre teorías psicodinámicas, conductistas y biológicas transcurrieron casi cuatro décadas, hasta que el autismo fue incorporado a los manuales diagnósticos. A partir de los años 80 una parte importante de los profesionales implicados en el autismo basa el diagnóstico en criterios consensuados que permiten delimitar grupos homogéneos, sin los cuales sería estéril la investigación y el intercambio de conocimientos. Pero los criterios actuales, y sobre todo la ubicación nosológica del autismo, parecen estar todavía lejos de ser consolidados. Posiblemente las aportaciones del DSM 5 sean el inicio de un giro radical

ThresholdROC: optimum threshold estimation tools for continuous diagnostic tests in R

We introduce an R package that estimates decision thresholds in diagnostic settings with a continuous marker and two or three underlying states. The package implements parametric and non-parametric estimation methods based on minimizing an overall cost function, as well as confidence interval estimation approaches to account for the sampling variability of the cut-off. Further features of the package include sample size determination and estimation of diagnostic accuracy measures. We used randomly generated data and two real datasets to illustrate the capabilities and characteristics of the package

Photonic stop bands in quasi-random nanoporous anodic alumina structures

The existence of photonic stop bands in the self-assembled arrangement of pores in porous anodic alumina structures is investigated by means of rigorous 2D finite- difference time-domain calculations. Self-assembled porous anodic alumina shows a random distribution of domains, each of them with a very definite triangular pattern, constituting a quasi-random structure. The observed stop bands are similar to those of photonic quasicrystals or random structures. As the pores of nanoporous anodic alumina can be infiltrated with noble metals, nonlinear or active media, it makes this material very attractive and cost-effective for applications including inhibition of spontaneous emission, random lasing, LEDs and biosensors

Evaluation of optimal control formulations for obtaining dynamically consistent walking motions

n recent years, interest has grown in predicting human motion, for example, to study cause-effect relations for a specific task [1]. To predict human motion, researchers typically use optimization-based methods that minimize a certain cost function. The objective of this study is to analyze two different optimal control formulations that track experimental data from a healthy gait cycle to obtain a dynamically consistent walking motion, i.e., with minimal residual wrench applied to the pelvis.Postprint (published version
