Using the Logistic Coupled Map for Public Key Cryptography under a Distributed Dynamics Encryption Scheme
Autor: Hugo Solís-Sánchez, E. Gabriela Barrantes
Publikováno v: Information, Vol 9, Iss 7, p 160 (2018)
Nowadays, there is a high necessity to create new and robust cryptosystems. Dynamical systems have promised to develop crypto-systems due to the close relationship between them and the cryptographic requirements. Distributed dynamic encryption (DDE)

The Early Scientific Contributions of J. Robert Oppenheimer: Why Did the Scientific Community Miss the Black Hole Opportunity?
Autor: Eduardo Boza-Oviedo, Marianela Quirós-Rojas, Kenneth Chaves-Cruz, Hugo Solís-Sánchez, Milena Guevara-Bertsch, Sofía Vargas-Hernández, Ariadna Venegas-Li, Manuel Ortega-Rodríguez
Publikováno v: Physics in Perspective. 19:60-75
We aim to carry out an assessment of the scientific value of Oppenheimer's research on black holes in order to determine and weigh possible factors to explain its neglect by the scientific community, and even by Oppenheimer himself. Dealing primarily

Given the peculiar and (in spite of many efforts) unexplained quasi-periodic oscillation (QPO) twin peak phenomena in accretion disc PSD observations, the present exploratory analytical article tries to inquire deeper into the relationship between di

Exploiting the fact that natural languages are complex systems, the present exploratory article proposes a direct method based on frequency distributions that may be useful when making a decision on the status of problematic phonemes, an open problem

Diskoseismology, the theoretical study of normal mode oscillations in geometrically thin, optically thick accretion disks, is a strong candidate to explain some QPOs in the power spectra of many black hole X-ray binary systems. The existence of g-mod

Artículo científico -- Universidad de Costa Rica, Cenrtro de Investigaciones Geofísicas. 2013 We propose a simple toy model to explain the 2:3:6 quasi-periodic oscillation (QPO) structure in GRS 1915+105 and, more generally, the 2:3 QPO structure

Titanium films were deposited on quartz, glass, polyamide and PET substrates in a high vacuum system at room temperature and their electrical resistance monitored in vacuo as a function of thickness. These measurements indicate that a low electrical
