Scientists are closer to unraveling the long-standing mystery of how tiny glass eel larvae, which begin their lives as hatchlings in the Sargasso Sea, know when and where to "hop off" the Gulf Stream ...
Characterization of the Overall and Internal Dynamics of Short Oligonucleotides by Depolarized Dynamic Light Scattering and NMR Relaxation Measurements

Let S be a monoidal category with equalizers that are preserved by the tensor
product. The notion of categories internal to S is defined, generalizing the notions
of monoid and comonoid in S, and ex...

2015/8/14
We introduce a two-type internal DLA model which is an example of a non-unary abelian network. Starting with n “oil” and n “water” particles at the origin, the particles diffuse in Z according to the ...
