Internally generated time in the rodent hippocampus is logarithmically compressed
eLife, 2022 The Weber-Fechner law proposes that our perceived sensory input increases with physical input on a logarithmic scale. Hippocampal ‘time cells’ carry a record of recent experience by firing sequentially during a circumscribed period of time after a ...

Fitting Heavy Tailed Distributions: The poweRlaw Package
Journal of Statistical Software, 2015 Over the last few years, the power law distribution has been used as the data generating mechanism in many disparate fields. However, at times the techniques used to fit the power law distribution have been inappropriate.

The invariances of power law size distributions [PDF]
F1000Research, 2016 Size varies. Small things are typically more frequent than large things. The logarithm of frequency often declines linearly with the logarithm of size. That power law relation forms one of the common patterns of nature. Why does the complexity of nature reduce to such a simple pattern?

Power-law Distribution Aware Trust Prediction [PDF]
Proceedings of the Twenty-Seventh International Joint Conference on Artificial Intelligence, 2018 Trust prediction, aiming to predict the trust relations between users in a social network, is a key to helping users discover the reliable information. Many trust prediction methods are proposed based on the low-rank assumption of a trust network.

Detecting the lead–lag effect in stock markets: definition, patterns, and investment strategies
Financial Innovation, 2022 Human activities widely exhibit a power-law distribution. Considering stock trading as a typical human activity in the financial domain, the first aim of this paper is to validate whether the well-known power-law distribution can be observed in this ...

Characterization of peak flow events with local singularity method [PDF]
Nonlinear Processes in Geophysics, 2009 Three methods, return period, power-law frequency plot (concentration-area) and local singularity index, are introduced in the paper for characterizing peak flow events from river flow data for the past 100 years from 1900 to 2000 recorded at 25 selected
