The Yule-Harding-Kingman (YHK) model and the proportional to distinguishable arrangements (PDA) model are two binary tree generating models that are widely used in evolutionary biology. Understanding the distributions of clade sizes under these two models provides valuable insights into macro-evolutionary processes, and is important in hypothesis testing and Bayesian analyses in phylogenetics. ...

A horde of cation-nonselective ion channel clans populate cell membranes. Their number is further augmented by removing extracellular calcium ([Ca 2 ] o ), turning well-behaved Ca 2 -selective channels into less discriminating sieves (Kostyuk and Krishtal, 1977; Almers and McCleskey, 1984). The Ca 2 ion stems the flood of ions moving through many cation channels by lodging in their throats, obs...

Proteases regulate various aspects of the life cycle in all organisms by cleaving specific peptide bonds. Their action is so central for biochemical processes that at least 2% of any known genome encodes for proteolytic enzymes. Here we show that selected proteases pairs, despite differences in oligomeric state, catalytic residues, and fold, share a common structural organization of functionall...

For centuries indigenous peoples have been identified with subsistence economies, meaning that productive activities were mainly intended to satisfy local needs. Even when other pursuits such as production for the market, trading and migrant wage or contract labor was present, hunting, gathering and cultivation for subsistence would ensure the survival of local territorial units, be they famili...
