Paul Winters and Susana Sitja Rubio The purpose of this guideline is to discuss the objectives and approaches of regional (subnational) development programs in order to provide guidance on issues related to evaluating the impact of these programs. Regional development programs are designed to improve the income-generating capacity of, and reduce poverty in, a focus region within a country. The ...

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...

Roussel and Rubio proved a lemma which is essential in the proof of the Strong Perfect Graph Theorem. We give a new short proof of the main case of this lemma. In this note, we also give a short proof of Hayward’s decomposition theorem for weakly chordal graphs, relying on a Roussel–Rubio-type lemma. We recall how Roussel–Rubio-type lemmas yield very short proofs of the existence of even pairs ...

Spiders of the corinnid genus Myrmecotypus Pickard-Cambridge, 1894 are known for being morphological and behavioral mimics of ants (Reiskind 1969, 1977; Cushing 1997, 2012; Rubio & Arbino 2009; Rubio et al. 2013). This genus currently includes nine species from to the New World. They occur from the United States (one species) to Argentina (one species), but most (seven species) occur from Mexic...

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...

Marine Research Center volunteer staff who assisted in data collection and entry. We also would like to thank Debbie Marrin, Terry Samansky and the Marine Mammal Department training staff at Six Flags Marine World who were responsible for the care and husbandry of the animals.

Let Sω f = ∫ ω f̂(ξ)e dξ be the Fourier projection operator to an interval ω in the real line. Rubio de Francia’s Littlewood–Paley inequality (Rubio de Francia, 1985) states that for any collection of disjoint intervals Ω, we have ∥∥∥∥ [∑ ω∈Ω |Sω f | 1/2∥∥∥∥ p ‖f‖p, 2 ≤ p < ∞. We survey developments related to this inequality, including the higher dimensional case, and consequences for multiplie...
