2221por Kim, Jinkyung, Kwon, Namseop, Chang, Soeun, Kim, Kyong-Tai, Lee, Dongmyeong, Kim, Seunghwan, Yun, So Jeong, Hwang, Daehee, Kim, Jee Woong, Hwu, Yeukuang, Margaritondo, Giorgio, Je, Jung Ho, Rhyu, Im Joo“…Despite these alterations, the 3-D quantitative analysis of the branching patterns showed no significant changes of the 77 ± 8° branch angle, whereas the branch segment length strongly increased with large fluctuations, comparing to control. The 3-D fractal dimension of the PCs decreased from 1.723 to 1.254, indicating a significant reduction of dendritic complexity. …”

2222“…The prognostic power of various measures, except of those reflecting rapid R–R interval oscillations, has been almost identical, albeit some non-linear HR variability measures, such as short-term fractal scaling exponent, and HR turbulence, have provided somewhat better prognostic information than the others. …”

Moreover, the two phenotypes display different aggregation profiles and adherent behavior on the substrate. …”

2228por Miramontes, Octavio, DeSouza, Og, Paiva, Leticia Ribeiro, Marins, Alessandra, Orozco, Sirio“…Going beyond the current trend of statistical model fitting alone, our study analyses anomalous diffusion and structure functions to estimate values of the scaling exponents describing displacement statistics. We evince the fractal nature of the movement patterns and show how the scaling exponents describing termite space exploration intriguingly comply with mathematical relations found in the physics of transport phenomena. …”
