“…However, in solid samples, the growing microbial film (bacterial colony) itself contains more characteristic information other than the individual cell shape. For example, E. coli, Listeria, and Bacillus cells are all rod-shaped, but their colony characteristic show dramatic differences [28]. In addition, nutrition, agar hardness, and environmental factors have been reported to change the morphology of the solid colony.…”

We report a multispectral elastic-light-scatter instrument that can simultaneously detect three-wavelength scatter patterns and associated optical densities from individual bacterial colonies, overcoming the limits of the single-wavelength predecessor. Absorption measurements on liquid bacterial samples revealed that the spectroscopic information can indeed contribute to sample differentiability. New optical components, including a pellicle beam splitter and an optical cage system, were utilized for robust acquisition of multispectral images. Four different genera and seven shiga toxin producing E. coli serovars were analyzed; the acquired images showed differences in scattering characteristics among the tested organisms. In addition, colony-based spectral optical-density information was also collected. The optical model, which was developed using diffraction theory, correctly predicted wavelength-related differences in scatter patterns, and was matched with the experimental results. Scatter-pattern classification was performed using pseudo-Zernike (GPZ) polynomials/moments by combining the features collected at all three wavelengths and selecting the best features via a random-forest method. The data demonstrate that the selected features provide better classification rates than the same number of features from any single wavelength. Three wavelength-merged scatter pattern from E. coli.

“…Antes de regresar a los Diálogos de Amor para una referencia final, hay que darle una rápida mirada a la transformación del diálogo como forma literaria de expresión durante la Edad Media. Se trata, naturalmente, solo de un comentario general, pero una de las primeras constataciones que debemos hacer es que casi mil años después de la condena de Agustín al diálogo ciceroniano, fue Petrarca quien, con su Secretum, hizo que regrese a circulación una vez más, si no su forma, al menos el espíritu del diálogo antiguo (Petrarca, 1978(Petrarca, , 1989(Petrarca, , 1993. El Secretum puede ser descrito como un intercambio, parecido al soliloquio, entre la personalidad literaria del autor y su conciencia agustiniana (Marsh, 1980, p. 4) 11 .…”

Mi intención, en este ensayo, es analizar la relevancia de la forma de expresión dialógica en el contexto de la tradición del pensamiento occidental. Como forma literaria, el diálogo tiene sus orígenes en Grecia durante el siglo V a. C., habiendo florecido de manera particular durante el siglo que vio la aparición de los escritos filosóficos de autores tales como Jenofonte, Platón e incluso Aristóteles. Etimológicamente, la palabra dialogos se refiere a una discusión investigativa, distinta de una simple conversación, o logos. En la Edad Media, sin embargo, popularmente se llegó a considerar el diálogo como limitado a solo dos personas.
