Because mutations are inevitable, the genome of each cell in a multicellular organism becomes unique and therefore encodes a record of its ancestry. Here we coupled arbitrary single primer PCR with ...

In this note the conditions on an invariance principle for triangular arrays of random variables contained in an earlier paper are weakened. Random norming by ...

Let K be a compact convex subset of a real Hilbert space, H; T: K → K a continuous pseudocontractive map. Let {an}, {bn}, {cn}, {an ′}, {bn ′} and {cn ′} be real sequences in [0,1] satisfying ...

Researchers have developed two types of programmable repressor elements that can switch off the production of an output protein in synthetic biology circuits by up to 300-fold in response to almost ...
