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...

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...
متن کاملPractical Construction of Metric t - Spanners ∗ Gonzalo
Let G(V,A) be a connected graph with a nonnegative cost function d : A → R. Let dG(u, v) be the cost of the cheapest path between u, v ∈ V . A tspanner of G is a subgraph G(V,E), E ⊆ A, such that ∀ u, v ∈ V, dG′(u, v) ≤ t · dG(u, v), t > 1. We focus on the metric space context, which means that A = V ×V , d is a metric, and t ≤ 2. Several algorithms to build t-spanners are known, but they do no...
متن کاملVirginia Apgar (1909-1974)
Virginia Apgar worked as an obstetrical anesthesiologist, administering drugs that reduce women's pain during childbirth, in the mid-twentieth century US. In 1953, Apgar created a scoring system using five easily assessable measurements, including heart rate and breathing rate, to evaluate whether or not infants would benefit from medical attention immediately after birth. Apgar's system showed...
