Aparición de la escala en las redes aleatorias
Resumen
Las grandes redes, como la World Wide Web, exhiben propiedades libres de escala debido al crecimiento continuo y al apego preferencial. Esto sugiere que los principios robustos de autoorganización gobiernan el desarrollo de la red.
Área de la Ciencia:
- Ciencia de los sistemas complejos ciencia de los sistemas complejos.
- Teoría de la red Teoría de la red Teoría de la red Teoría de la red Teoría de la red Teoría de la red
- Física estadística de las estadísticas.
Sus antecedentes:
- Muchos sistemas a gran escala, incluidas las redes genéticas y la World Wide Web, exhiben topologías complejas.
- Una característica común de estas redes es una distribución libre de escala de la ley de potencia de las conectividades de vértices.
Objetivo del estudio:
- Identificar los mecanismos subyacentes responsables de la propiedad libre de escala en redes complejas.
- Desarrollar un modelo que explique el surgimiento de distribuciones libres de escala estacionaria.
Principales métodos:
- El estudio propone un modelo basado en dos mecanismos clave: la expansión continua de la red mediante la adición de nuevos vértices.
- El modelo incorpora la fijación preferencial, donde los nuevos vértices se conectan a los vértices existentes ya bien conectados.
Principales resultados:
- El modelo propuesto reproduce con éxito las distribuciones libres de escala estacionaria observadas en redes complejas.
- Los hallazgos indican que el desarrollo de la red está impulsado por fenómenos genéricos de autoorganización.
Conclusiones:
- La propiedad libre de escala de las grandes redes es una consecuencia de mecanismos de autoorganización simples y robustos.
- Estos mecanismos operan independientemente de los detalles específicos de los sistemas de red individuales, destacando los principios universales en el crecimiento de la red.

Mutation, Gene Flow, and Genetic Drift
In a population that is not at Hardy-Weinberg equilibrium, the frequency of alleles changes over time. Therefore, any deviations from the five conditions of Hardy-Weinberg equilibrium can alter the genetic variation of a given population. Conditions that change the genetic variability of a population include mutations, natural selection, non-random mating, gene flow, and genetic drift (small population size).Mechanisms of Genetic VariationThe original sources of genetic variation are mutations,...
Genetic Drift
Natural selection—probably the most well-known evolutionary mechanism—increases the prevalence of traits that enhance survival and reproduction. However, evolution does not merely propagate favorable traits, nor does it always benefit populations.Life is not fair. A deer grazing contentedly in a field can have her meal cut tragically short by a bolt of lightning. If the doomed doe is one of only three in the population, 1/3 of the population’s gene pool is lost. Random events like this can...
Genome Size and the Evolution of New Genes
While every living organism has a genome of some kind (be it RNA, or DNA), there is considerable variation in the sizes of these blueprints. One major factor that impacts genome size is whether the organism is prokaryotic or eukaryotic. In prokaryotes, the genome contains little to no non-coding sequence, such that genes are tightly clustered in groups or operons sequentially along the chromosome. Conversely, the genes in eukaryotes are punctuated by long stretches of non-coding sequence.
Random Sampling Method
Sampling is a technique to select a portion (or subset) of the larger population and study that portion (the sample) to gain information about the population. Data are the result of sampling from a population. The sampling method ensures that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest. Among the various sampling methods used by...
Random Variables
A random variable is a single numerical value that indicates the outcome of a procedure. The concept of random variables is fundamental to the probability theory and was introduced by a Russian mathematician, Pafnuty Chebyshev, in the mid-nineteenth century.
Uppercase letters such as X or Y denote a random variable. Lowercase letters like x or y denote the value of a random variable. If X is a random variable, then X is written in words, and x is given as a number.
For example, let X = the...

Randomized Experiments
The randomization process involves assigning study participants randomly to experimental or control groups based on their probability of being equally assigned. Randomization is meant to eliminate selection bias and balance known and unknown confounding factors so that the control group is similar to the treatment group as much as possible. A computer program and a random number generator can be used to assign participants to groups in a way that minimizes bias.
