Unified scaling of polar codes: Error exponent, scaling exponent, moderate deviations, and error floors [PDF]

open access: yes2015 IEEE International Symposium on Information Theory (ISIT), 2015
Consider the transmission of a polar code of block length $N$ and rate $R$ over a binary memoryless symmetric channel $W$ and let $P_e$ be the block error probability under successive cancellation decoding. In this paper, we develop new bounds that characterize the relationship of the parameters $R$, $N$, $P_e$, and the quality of the channel $W ...

Scale-free networks with exponent one [PDF]

open access: yesPhysical Review E, 2016
A majority of studied models for scale-free networks have degree distributions with exponents greater than $2$. Real networks, however, can demonstrate essentially more heavy-tailed degree distributions. We explore two models of scale-free equilibrium networks that have the degree distribution exponent $γ= 1$, $P(q) \sim q^{-γ}$.

Scaling exponents for ordered maxima

open access: yesPhysical Review E, 2015
We study extreme value statistics of multiple sequences of random variables. For each sequence with N variables, independently drawn from the same distribution, the running maximum is defined as the largest variable to date. We compare the running maxima of m independent sequences, and investigate the probability S_N that the maxima are perfectly ...

Scaling laws and electricity consumption in cities: a sectoral view

open access: yesInternational Journal of Sustainable Energy Planning and Management, 2014
With the use of electricity being increasingly concentrated in urban areas it becomes important to understand the influence of cities, and their size, on patterns of consumption. We tested the application of the scaling law to the Portuguese urban system,

Modeling fractal structure of city-size distributions using correlation functions.

open access: yesPLoS ONE, 2011
Zipf's law is one the most conspicuous empirical facts for cities, however, there is no convincing explanation for the scaling relation between rank and size and its scaling exponent.

Effect of pulse laser frequency on PLD growth of LuFeO3 explained by kinetic simulations of in-situ diffracted intensities

open access: yesScientific Reports, 2022
Atomistic processes during pulsed-laser deposition (PLD) growth influence the physical properties of the resulting films. We investigated the PLD of epitaxial layers of hexagonal LuFeO $$_3$$ 3 by measuring the X-ray diffraction intensity in the ...

Scaling Exponents of Time Series Data: A Machine Learning Approach

open access: yesEntropy, 2023
In this study, we present a novel approach to estimating the Hurst exponent of time series data using a variety of machine learning algorithms. The Hurst exponent is a crucial parameter in characterizing long-range dependence in time series, and ...

Sizing up allometric scaling theory. [PDF]

open access: yesPLoS Computational Biology, 2008
Metabolic rate, heart rate, lifespan, and many other physiological properties vary with body mass in systematic and interrelated ways. Present empirical data suggest that these scaling relationships take the form of power laws with exponents that are ...
