The absolute value of the Möbius function of a bounded poset P with n + 2 elements satisfies |μ(P )| ≤ max r≥0 max p1+...+pr=n pi≥1 r ∏

This article takes its name and inspiration from Mad Professor’s album A Caribbean Taste of Technology in response to the theme of this Technosphere issue. This makes a good place to start a discussion of creolization and technology – the dub reggae tracks of this album produced British producer Mad Professor and released in 1985, https://www.youtube.com/watch?v=ewDTHfJqLwI So what I present he...

Infrared measurements and linear-spin-wave calculations for single-crystal Y12xPr xBa2Cu3O6 (x50.0, 0.4, 1.0! in magnetic fields up to 30 T show that absorption features which have been ascribed to magnon excitations are very insensitive to the applied field. The substitution of Pr for Y leads to an additional absorption feature, which does have a strong field dependence. This excitation is ass...

Women with inherited BRCA1 mutations have an elevated risk (40-80%) for developing breast and ovarian cancers. Reproductive history has been reported to alter this risk, suggesting a relationship between ovarian hormone signaling and BRCA1-related tumor development. BRCA1 interactions with estrogen receptor (ER) and progesterone receptor (PR) signaling were previously described in human breast ...

Ordered and accurate processing of the human immunodeficiency virus type 1 (HIV-1) GagPol polyprotein precursor by a virally encoded protease is an indispensable step in the appropriate assembly of infectious viral particles. The HIV-1 protease (PR) is a 99-amino-acid enzyme that is translated as part of the GagPol precursor. Previously, we have demonstrated that the initial events in precursor...
