A preliminary differential proteomic analysis of the periplasmic fraction in Acidithiobacillus ferrooxidans planktonic and attached cells exposed to chalcopyrite
(2009-12-28)
The Acidithiobacillus ferrooxidans periplasmic space is known to have proteins involved in the respiratory chains. There are no reports about the expression of the periplasmic proteins in A. ferrooxidans cells attached to ...
Cross-entropy embedding of high-dimensional data using the neural gas model
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-06)
A cross-entropy approach to mapping high-dimensional data into a low-dimensional space embedding is presented. The method allows to project simultaneously the input data and the codebook vectors, obtained with the Neural ...
Nuevo enfoque combinatorio para el problema del paseo al azar en un espacio n-Dimensional
(Universidad Nacional (Costa Rica), 1994)
Se presenta un nuevo enfoque combinatorio para resolver el problema del cálculo de las probabilidades de paso –probabilidades de transición entre dos posiciones cualesquiera- de una partícula que se desplaza siguiendo una ...
One-loop n-point equivalence among negative-dimensional, Mellin-Barnes and Feynman parametrization approaches to Feynman integrals
(Iop Publishing Ltd, 2003-11-28)
We show that at one-loop order, negative-dimensional, Mellin-Barnes (MB) and Feynman parametrization (FP) approaches to Feynman loop integral calculations are equivalent. Starting with a generating functional, for two and ...

New solutions of the D-dimensional Klein–Gordon equation via mapping onto the nonrelativistic one-dimensional Morse potential
(2017-03-01)
New exact analytical bound-state solutions of the D-dimensional Klein–Gordon equation for a large set of couplings and potential functions are obtained via mapping onto the nonrelativistic bound-state solutions of the ...
