The polyether antibiotics reported by the year 1968 were nigericin1) (X-4642)), lasalocid (X-537A2)), X-2062), dianemycin3) and monensin4). Monensin (1) was the only one whose structure was known at that time. In the following decade, the number of distinct polyethers increased from these five to forty-six, almost all of which were structurally assigned. As a result of this rapid growth, a numb...

Abstract The objective of this study is to analyze the relationship between views (popularity) and social interaction generated by YouTuber videos in Spanish.

Joint modeling of spatially oriented dependent variables is commonplace in the environmental sciences, where scientists seek to estimate relationships among a set outcomes accounting for dependence these and spatial each outcome. Such now sought massive data sets with measured at very large number locations. Bayesian inference, while attractive accommodating uncertainties through hierarchical s...

Nowhere are the barriers to a functional health infrastructure more clearly on display than in the Goma region of Democratic Republic of Congo. Kaboru et al. report poorly integrated services for HIV and TB in this war-torn region. Priorities in conflict zones include provision of security, shelter, food, clean water and prevention of sexual violence. In Goma, immediate health priorities includ...

In this note, we will generalize most of the results in [4], replacing the Witt polynomials wn by the more general polynomials wF,n defined for any pseudo-monotonous map F : P × N → N (the meaning of ”pseudo-monotonous” will soon be explained below). Whenever possible, the proofs will be done by simply copypasting the corresponding proofs from [4] and doing the necessary changes which often wil...
