QnAs with Angel Rubio.
Just as physics requires a different set of tools to explore phenomena at the quantum scale, chemistry requires a quantum paradigm. At the macroscale, the interaction of light with chemical entities can be observed in processes such as photosynthesis. But the actual interaction between photons and other matter occurs in the realm of quantum chemistry. National Academy of Sciences member and phy...

The problem of known signal detection in Additive White Gaussian Noise is considered. In this paper a new detection algorithm based on Discrete Wavelet Transform pre-processing and threshold comparison is introduced. Current approaches described in [7] use the maximum value obtained in the wavelet domain for decision. Here, we use all available information in the wavelet domain with excellent r...

bution of host genetic factors (the FUT2 genotype in particular) on differences in the gut microbiota between patients with Crohn disease and healthy individuals. Thus, an intimate relation between host genetics and bioactive components is expected and should be linked to both infant microbiota colonization and immune system development. The process of microbial colonization of the infant’s gut...

Ignacio Vives Ponseti developed a noninvasive method for treating congenital club foot in the US during the late 1940s. Congenital club foot is a birth deformity in which one or both of an infant's feet are rotated inward beneath the ankle, making normal movement rigid and painful. Ponseti developed a treatment method, later called the Ponseti method, that consisted of a series of manipulations...

The effect of pH on the relative distribution of pyridoxal structures in aqueous solution was examined by fluorescence spectroscopy. The hemiacetal structure, which is the predominant species at neutral pH, exhibits a symmetrical emission band at 378 rnp and is characterized by a quantum yield of 0.08. Luminescence studies at low temperature (77” K) have permitted the analysis of the phosphores...
