(AMER INST PHYSICS, 2008-07-21)We describe a simple method to control a known unstable periodic orbit UPO in the presence of noise. The strategy is based on regarding the control method as an optimization problem, which allows us to calculate a ...
-
(American Society of Agricultural and Biological Engineers, 2005)This work reports on the determination of the optimal operating conditions for an optical ring sensor system as a first step in its use for fruits and vegetable sizing. The system was comprised of a singulator which fed ...
-
(ACADEMIC PRESS LTD ELSEVIER SCIENCE LTD, 2006-12)Chemical, electrochemical and flow variables were optimized to examine the effectiveness of the electrocoagulation process for the removal of copper, lead and cadmium. The electrochemical process, which uses electrodes of ...
-
(Elsevier, 2014)Stochastic volatility models have been widely studied and used in the financial world. The Heston model (Heston, 1993) [7] is one of the best known models to deal with this issue. These stochastic volatility models are ...
-
(Wiley, 2020)The bonding and antibonding character of individual molecular orbitals has been previously shown to be related to their orbital energy derivatives with respect to nuclear coordinates, known as dynamical orbital forces. ...
-
(2016)AimOrchidaceae is the most species-rich angiosperm family and has one of the broadest distributions. Until now, the lack of a well-resolved phylogeny has prevented analyses of orchid historical biogeography. In this study, ...
-
(2007)An ordered self-assembly of gold nanoparticles (AuNPs) onto microcrystal faces of a 2 alpha-cyclodextrin-dodecanethiol (2 alpha CD-DDT) inclusion compound (IC) by means of a magnetron sputtering technique was obtained. The ...

(1995)A Reply to the Comment by James W. Dufty, Roland Stamm, and Bernard Talin. © 1995 The American Physical Society.
-
(1992)The recombinant plasmid pTR‐3 was previously shown to contain part of the 16S and 23S ribosomal RNA genes and the spacer region between the two genes from operon rrnT, from Thiobacillus ferrooxidans. The spacer region was ...
-
(Elsevier Ltd., 2005-08-24)This article analyses the work of Robert Rosen on an interpretation of metabolic networks that he called ðM;RÞ systems. His main contribution was an attempt to prove that metabolic closure (or metabolic circularity) could ...
-
Organometallic derivatives of polyphosphazenes as precursors for metallic nanostructured materials (SPRINGER, 2006-12)Co-polyphosphazenes containing anchored organometallic fragments are useful precursors for nanostructured metallic materials. Pyrolysis in air at 800 degrees yields metallic nanoparticles of the type, M degrees/M (x) O (y) ...
-
(Elsevier, 2000)The three new organometallic hydrazines [Fe(η5-Cp)(η6-RC6H4NHNH 2)]+PF6 -, Cp=C5H5, R=H, [1]+PF6 -; m-Me, [2]+PF6 -; p-MeO, [3]+PF6 -, were synthesised and characterised. They were obtained in CH2Cl2 by reaction of the ...
-
(Sociedad de Neurología, Psiquiatría y Neurocirugía, 1991-08)A model of conscioussness rooted in the concept of intentionalit y is presented. Intentionallity is analyzed from some phylasophical sources. From this analysis it appears clear chat in ten tionalit y is (he nec/]SS8ry ...
-
(SOC NEUROSCIENCE, 2010-01-11)The lateral line system of teleosts has recently become a model system to study patterning and morphogenesis. However, its embryonic origins are still not well understood. In zebrafish, the posterior lateral line (PLL) ...
-
(Sociedad Mexicana de Fisica, 2014)A mechanism that produces conical dispersion relations is presented. A Kronig Penney one dimensional array with two different strengths delta function potentials gives rise to both the gap closure and the dispersion relation ...
-
(ACADEMIC PRESS INC ELSEVIER SCIENCE, 2005-05)We addressed phylogenetic relationships in the genus Trachurus using cytochrome b gene and D-loop sequences. The trees showed five groups: (1) the Southwest Pacific species (T. japonicus, T. novaezelandiae, and T. declivis); ...

-
(ROYAL SOC CHEMISTRY, 2016)The mechanism of the ANRThe mechanism of the ANRORC-like ring transformation of nitroimidazole derivatives towards aniline has been studied by fully exploring the potential energy surface (PES). For this purpose the reaction ...

Osmoregulation and adaptive radiation in the ovenbird genus Cinclodes (Passeriformes : Furnariidae) (BLACKWELL, 2006-10)1. The genus Cinclodes is unique among passerines because it includes two species that can be considered marine/coastal and also includes several species that inhabit freshwater streams or that shift habitats between ...
