Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
Resumen A través de la criptografía, se desea modificar y ocultar cierta información, para que sólo algún grupo determinado de personas pueda interpretarlo por medio de una clave. Al tratar de utilizar diversos campos de la matemática para realizar este proceso, se desarrolla el concepto de criptografía matemática. La mayoría de métodos criptográficos matemáticos se concentran en teoría de números. También exiten otros métodos criptográficos en el área de física cuántica y geometría algebraica, particularmente elíptica y curvas hyperelípticas definidas sobre cuerpos y campos finitos, finito campos, entre otros. El presente trabajo introduce una nueva modalidad del aspecto de procesamiento de señales al campo de la criptografía matemática, a través de representaciones armónicas bidimensionales como lo es la función discreta de ambigüedad. Este trabajo utiliza dos definiciones equivalentes, en módulo, de la función discreta de ambigüedad. Este nuevo método criptográfico utiliza el concepto de clave simétrica para efectuar el proceso de cifrar y descifrar el mensaje.
