If a piecewise constant function is integrated, the result is okay, if 2 integrals are nested, that's okay too, but 3 times the result is 'nan' which it shouldn't be: from sympy import * a1, a2, a3 = ...

Abstract: In nanopore sequencers, single-stranded DNA molecules (or k-mers) enter a small opening in a membrane called a nanopore and modulate the ionic current through the pore, producing a channel ...

Abstract: We propose a progressive particle filter that inherently avoids sample degeneracy by splitting the likelihood into a product of wider functions applied step by step. Between steps, the ...
