Diseños de bloques balanceados incompletos (bibd) a través de un enfoque matricial

open access: yes, 2006
Frecuentemente en la experimentación a través del diseño de bloques incompletos, encontramos que la información de la matriz es una matriz singular, razón por la cual esta matriz no es invertible.

18F‑Labeled PET Tracers Specific for Adenosine A2A Receptor: Design, Synthesis, and Biological Evaluation

open access: yes
By modifying the structures of targeted A2AR antagonists and tracers, novel compounds 3, 7a, 9, 12c, and BIBD-399 were designed and synthesized. In vitro inhibition experiments demonstrated that 3, 12c, and BIBD-399 have high affinity for A2AR.

A ring partition construction for bibds

open access: yesRevista Técnica de la Facultad de Ingeniería, 2011
A method for finding initial difference blocks for certain balanced incomplete block designs by means of partitions of elements in finite rings is given. It is shown that multiplier theory for difference sets, when expressed. It terms of finite rings, can be useful in certain instances for obtaining appropriate partitions.
