Complex networks have attracted growing attention in many fields. As a generalization of fractal analysis, multifractal analysis (MFA) is a useful way to systematically describe the spatial heterogeneity of both theoretical and experimental fractal patterns. Some algorithms for MFA of unweighted complex networks have been proposed in the past a few years, including the sandbox (SB) algorithm re...

We study how the information and communications technology (ICT) ecosystem affects the sustainable growth of ICT firms. For our study, we analyze the efficiencies of ICT firms in China, South Korea, the United States, and Japan, which are the current leaders in the global ICT industry, each with different ICT ecosystem structures. We use metafrontier analysis (MFA) to compare the efficiencies a...

Contamination of magnetoencephalogram (MEG) records by various artifacts seriously influences the estimation accuracy of magnetic sources. Although some methods have been proposed to reject contaminated records [1][2], most of them are ineffective when artifacts models are not available. In this study, we proposed to classify MEG records into contaminated records and others by mixture of factor...

Selection biases based on the use of cut-off dates and the timing of athletes' birthdates have been termed relative age effects. These effects have been shown to differentially affect individuals involved in sport. For example, young male soccer players born early in their age group are overrepresented in elite teams while studies in adult soccer indicated potential carry-over effects from tale...

At the end of 19th and beginning 20th centuries, process Europeanization Central Asian region began. A certain stagnation in development traditional culture changing socio-cultural conditions predetermined need to introduce new European forms painting, graphics, sculpture into Uzbekistan, or rather Turkestan. In 1920s, national school fine arts Uzbekistan was formed. During this decade, a uniqu...

We investigate the time evolution and steady states of the stochastic susceptible-infected-recovered-susceptible (SIRS) epidemic model on one- and two-dimensional lattices. We compare the behavior of this system, obtained from computer simulations, with those obtained from the mean-field approximation (MFA) and pair approximation (PA). The former (latter) approximates higher-order moments in te...

The current study used multilevel modeling of daily diary data to model within-person (state) and between-person (trait) components of coping variables. This application included the introduction of multilevel factor analysis (MFA) and a comparison of the predictive ability of these trait/state factors. Daily diary data was collected on a large (n = 366) multiethnic sample over the course of fi...

The artist is a landscape painter whose work addresses issues of land use and development. She is particularly inter­ ested in the many ways our built envi­ ronment has changed over time in re­ sponse to changes in our culture. She is currently an assistant professor at the Cleveland Institute of Art. She holds a BA from Yale and an MFA in painting from the University of Michi­ gan. To view mor...

Here, we highlight aspects of visualizing twins in the fine arts. The works artists Leonardo da Vinci, Jacopo Pontormo, Ker-Xavier Roussel, Jean-Bruno Gassies, Peter Paul Rubens, Sebastiano Ricci and others are presented.
