Abstract: This work is a descriptive study about a set of tools made –up for teachers of Medical Informatics I, for the Faculty of Medicine in Las Tunas. For the development of the theoretical-practical and for the practical lessons, it is offered electronic presentations, guidelines for practice activities and seminars, as well as an electronic book for the preparation of teachers. This work eases the preparation of teachers, a better planning of the students’ individualities. This work has favoured the quality in the teaching-learning process where human values are strengthened.
Cómo se llamaba el padre? // What is the father`s name?
Alexander Cruz Aponasenko
Affectio Societatis , 2010,
Abstract: Está a punto de estrenarse en cine, o quizás ya se estrenó en otras latitudes, la versión cinematográfica del último libro de Cormack McCarthy: La carretera. Galardonado con el Pulitzer por este último libro y conocido entre los lectores casuales gracias a su anterior novela: No country for old men, llevada al cine de forma impecable por los hermanos Cohen, McCarthy sorprende dejando ver que a lo largo de su obra, en particular en La carretera, aparece una pregunta por el padre. Tema que de continuo tratan los psicoanalistas, desafortunadamente no con la belleza con que lo hace el poeta. La obra de McCarthy es otro de los tantos ejemplos en los que la literatura ense a al psicoanálisis. // The premiere is ready or maybe it was showed in other latitudes the Cormack Mccarthy movie version of his last book: The Road. This last book won the Pulitzer Prize, also known among the casual readers for his previous novel: No country for old men, impeccable movie version by Cohen brothers. Along his work McCarthy surprise allowing to see, especially in The Road, a question for the father. Subject usually worked by the psychoanalysts, unfortunately, not with the same beauty that the poet does it. McCarthy’s work is other among many examples where the literature teaches to psychoanalysis.
El algoritmo de la transferencia como antecesor del discurso del amo. // The algorithm of transference as a predecessor of the master`s discourse.
Alexander Cruz Aponasenko.
Affectio Societatis , 2010,
Abstract: This work establishes the counter argument between Lacan’s elaboration discussed in the Proposition of October 9 on the Psychoanalyst of the School, regarding the transference, and the quadripode called “master’s discourse”, delivered in the 1969-1970 seminar. In the “Proposition”, Lacan shows a formula commonly known as “algorithm of transference”, which formalizes the opening to the unconscious through the transference signifier operation and allows the possibility of the analytical work by the installation of the subject-supposed-to-know. We will see how this algorithm precedes the master’s discourse or the discourse of the unconscious. Thus we are going to establish a directionality in the analytical cure by observing the reversal of the master’s discourse that is the discourse of the analyst. // El trabajo establece un contrapunto entre la elaboración de Lacan presentada en la proposición del 9 de octubre sobre el psicoanalista de la escuela, en relación a la transferencia, y el cuadrípodo denominado "discurso del amo", presentado en el seminario del a o 1969-1970. En la “proposición” Lacan presenta una fórmula conocida coloquialmente como "algoritmo de la transferencia", que permite formalizar la apertura al inconsciente mediante la operación del significante de la transferencia y producir allí la posibilidad del trabajo analítico vía la instalación del sujeto supuesto saber. Veremos cómo este algoritmo antecede al discurso del amo o discurso del inconsciente. Esto nos permitirá establecer una direccionalidad en la cura analítica observando la inversión del discurso del amo que es el discurso del analista.
A stochastic approximation algorithm with multiplicative step size adaptation
Alexander Plakhov,Pedro Cruz
Mathematics , 2005,
Abstract: An algorithm of searching a zero of an unknown undimensional function is considered, measured at a point x with some error. The step sizes are random positive values and are calculated according to the rule: if two consecutive iterations are in same direction step is multiplied by u>1, otherwise, it is multiplied by 01, divergence. Due to the multiplicative rule of updating of the step, it is natural to expect that the sequence converges rapidly: like a geometric progression (if convergence takes place), but the limit value may not coincide with, but instead, approximates one of zeros of the function. By adjusting the parameters u and d, one can reach necessary precision of approximation; higher precision is obtained at the expense of lower convergence rate.
Observational discovery of the AGB-bump in densely populated color-magnitude diagrams of galaxies and star clusters
Carme Gallart
Physics , 1997, DOI: 10.1086/311218
Abstract: The huge photometric databases that are being created for stars in the Magellanic Clouds and in Local Group galaxies not only allow detailed study of the star formation history of these systems, but also provide important information on stellar evolutionary theory. Two low-level features above the red-clump in the LMC color-magnitude diagram (CMD) have been discussed by Zaritsky & Lin (1997) and Alcock et al. (1997) as the possible signature of an intervening population. I conclude that one of the features, which has also been associated with the red giant branch bump (RGB-bump) predicted by theory and observed in globular clusters, is instead produced during asymtotic giant branch (AGB) evolution. I will call it the AGB-bump. In this paper, it will be shown that the stellar evolution predictions about the position and strength of the AGB-bump are in very good agreement with the observed structures in the LMC, M31 and globular clusters. The position in the CMD of the other feature is consistent with the location of the blue-loops of a few Myr old stars and it has also been observed in the CMD of other galaxies with a young stellar population.

Comparison of Different Models for the Simulation of Photovoltaic Panels  [PDF]
Luisa Fernanda Herrera Giraldo, Jeison Alexander Rodríguez Cruz, Johann Alexander Hernández Mora
Energy and Power Engineering (EPE) , 2016, DOI: 10.4236/epe.2016.88027
Abstract: This article contains the description of a circuital model, which was developed to represent the energy production of a photovoltaic panel in a more accurate way, taking into consideration the decrease of its operational time. Furthermore, a comparison among the experimental, the posed simulated model in PSIM and the results obtained by a piece of software developed by some students of the Universidad Distrital is performed in order to verify the values provided by the software and demonstrate the optimal operation of the developed model.
Behavioral Analysis of a Lithium Ion Battery (Li-Ion), a Nickel Metal Hydride Battery (Ni-MH) and a Supercapacitor in an Isolated Photovoltaic Solar System  [PDF]
Laura Milena Cruz Moreno, Diego Fabián Martín Rincón, Johann Alexander Hernández
Energy and Power Engineering (EPE) , 2017, DOI: 10.4236/epe.2017.94020
Abstract: This paper presents experimental research about the behavior of different storage devices such as Li-ion, Ni-MH batteries and supercapacitors when charged by a solar photovoltaic system. Photovoltaic systems work as a variable current source, depending on the solar irradiance. These devices present a different profile charge compared to a constant and controlled charge generated by a traditional charger. For this work, several charging and discharging cycles of batteries and supercapacitors under the same environmental conditions were carried out in order to observe the different characteristics of each technology, and some harmful effects on the storage devices operation such as the memory effect and partial discharges involved in the proper functioning of the solar photovoltaic system.

Revista Habanera de Ciencias M??dicas , 2010,
Abstract: the rising of nurses emergent schools brought within a whole new concept of human resources formation in infirmary. the massive ingoing of students and the integration of media education to professional education, were among the main characteristics of this emerging plan of formation for nurses as it was also known .from this new formation concept the number of ingoing professionals to post grade studies in their different forms were considerably increased. the following reflections has as a main purpose to announce considerations, from the author′s perspective, about the relation this new concept of human resources formation had in developing the post grade figures of infirmary carrier in cuba. remarking the element of the increase of ingoing professionals to these studies.to accomplish this purpose several bibliographies were reviewed, about the new nursing formation and the continuing education process topic in the cumed and lilacs data base. finally considerations are based on remarking the importance of the roll played by the maters nursing degree program, and the strategies carried out at the present, by post grade authorities in cuba to make available the consecution of scientific degrees. finally reasons of why the process that ensures the consecution of scientific degrees such as masters and phd in nursing in cuba is fully guarantee for the future are given .
Upper Bounds for Mutations of Potentials
John Alexander Cruz Morales,Sergey Galkin
Symmetry, Integrability and Geometry : Methods and Applications , 2013,
Abstract: In this note we provide a new, algebraic proof of the excessive Laurent phenomenon for mutations of potentials (in the sense of [Galkin S., Usnich A., Preprint IPMU 10-0100, 2010]) by introducing to this theory the analogue of the upper bounds from [Berenstein A., Fomin S., Zelevinsky A., Duke Math. J. 126 (2005), 1-52].
