Normal Fault Trace-Length Scaling in a Tectonic Transition Zone in Southern Sedna Planitia, Venus
… length plot (CNL) and fit with a power function, exponential function, and logarithmic function to determine which function best describes the trace-length distribution.A power function is the best fit with a scaling exponent of 1.73. This result is compared to previous studies of fault …

Change in Shoreline Position for Two Consecutive Years Using LIDAR Along the Outer Banks, North Carolina
… the signal (Malumud and Turcotte, 1999) with a scaling exponent that varies from 1.2 to 2.1. Four of the five selected sections of coast, Wavelet analysis of the shoreline change signal indicate the signal is self-affine with a scaling exponent that varies from 1.4 to 2.3. </p><p>The power …

Asymptotic analysis of the parametrically driven damped nonlinear evolution equation
… obtained by the multiple-scales technique. The scaling exponent for the damping coefficient and the correct time scale for the parametric resonance are obtained. We further employ the multiple-scales technique to derive the amplitude equation for the parametrically driven pendulum for the …

Environmental constraints on human memory
… constraints and observe changes in the scaling exponent. In Experiment one, I replicated the work of Rhodes and Turvey (2007), were it was found that participants’ inter-recall intervals (IRIs; the time-lapse between memories) reproduce a Lévy flight distribution. In Experiment 2, I used …

Characterization of hypertension through multivariate analysis utilizing linear and nonlinear methods
… Separation was accomplished by the long-term scaling exponent [alpha]2 from detrended fluctuation analysis and parameter SD2 from Poincare analysis. Linear results did not aid in subject separation. Linear analyses consisted of heart rate and blood pressure variability and baroreflex response. …

Metabolic Scaling Analysis of Building Energy Efficiency: A Case Study of Massachusetts Institute of Technology
… This research applies ecological metabolic scaling principles to building energy analysis, utilizing the Massachusetts Institute of Technology (MIT) campus as a case study. Analogous to biological systems, where an animal’s metabolic rate scales to 3/4 power of its mass, our findings …

Understanding the nuances of the rockfall frequency-magnitude relationship: review and examples from two original case studies in Glenwood Canyon, CO, USA
… physical and systematic factors on the power law exponent. The meta-analysis provides the strongest evidence for the influences of rockmass condition, geology, rockfall data collection method, and maximum inventory volume on the scaling exponent. Relationships between other variables and the …

An entropic approach to the analysis of time series.
… of Complexity that correctly determines the scaling hidden within a time series reflecting a Complex Process. The time series is thought of as a source of fluctuations, and the DEA is based on the Shannon entropy of the diffusion process generated by these fluctuations. All traditional …

Spin lattice relaxation studies on iron proteins
… dimension. These parameters are related as scaling exponents using simple physical arguments and experimental results. Central issues addressed are the domain of length scales over which the tabulated fractal dimension is a valid scaling exponent and the frequency range of protein vibrations …

Power-law liquid in high-temperature superconductors
… r\pr}\sim(\omega^{2}+\pi^{2}T^{2})^{\alpha}$. The scaling exponent decreases from $\alpha\sim1$ in the overdoped Fermi-liquid state to $\alpha\lesssim\frac{1}{2}$ in the optimal and underdoped regime. We find that broad scale invariance of a power-law liquid leads to the cuprates' superconducting …

Raman studies of the nanostructure of sol-gel materials
… nanocrystal size and α is a Raman-versus-size scaling exponent. For AlO(OH), I determined α to be 1.0, close to the scaling-exponent values reported for graphite and BN and different from the values (about 1.5) that describe the reported behavior of Si, Ge, and GaAs. The trihydroxide polymorph …

Multifractal analysis of heart rate variability using wavelet-transform modulus-maxima method
… analysis method provides the calculation of the scaling exponent ([tau](q)). For healthy subjects, the [tau](q) spectrum displays nonlinear behavior, while the [tau](q) spectrum is linear for congestive heart failure subjects. To validate the theory, analysis was performed on 50 subjects and we …

The metabolism of living space : allometric scaling of energy use in UK domestic buildings
… of building geometry and social practices on scaling relationships relating to domestic energy consumption. Scaling relationships relating to the physical building properties have been studied extensively, however none directly assess how total energy usage scales across the domestic building …

Sequence-Based Properties that Identify Intrinsically Disordered Phase-Separating Protein Regions
… sequence. This algorithm uses the polymer scaling exponent, v, and a conformational parameter, the intrinsic beta-turn propensity, to distinguish the three protein classes (folded, F; disordered, D; and phase-separating disordered, P). Here, we confirm that the v and beta-turn propensity …

Multiscale dynamics in honeybee societies
… interactions among humans. I propose a scaling argument to explain the scaling exponent of these distributions, and test the argument in simple random-walk models of proximity interactions. I then study the honeybee society at the collective scale of the trophallaxis interaction network, …
