SASfit: A comprehensive tool for small-angle scattering data analysis
Small-angle X-ray and neutron scattering experiments are used in many fields of the life sciences and condensed matter research to obtain answers to questions about the shape and size of nano-sized…

A highly specific test for periodicity
We present a method that allows to distinguish between nearly periodic and strictly periodic time series. To this purpose, we employ a conservative criterion for periodicity, namely that the time…

Allan variance computed in space domain: Application to InSAR data to characterize noise and geophysical signal
The Allan variance was introduced fifty years ago for analyzing the stability of frequency standards. Beside its metrological interest, it is also an estimator of the large trends of the power…

An algorithm for discovering Lagrangians automatically from data
An activity fundamental to science is building mathematical models. These models are used to both predict the results of future experiments and gain insight into the structure of the system under…

The Parabolic variance (PVAR), a wavelet variance based on least-square fit
This article introduces the Parabolic Variance (PVAR), a wavelet variance similar to the Allan variance, based on the Linear Regression (LR) of phase data. The companion article arXiv:1506.05009…

Least square fitting with one parameter less
It is shown that whenever the multiplicative normalization of a fitting function is not known, least square fitting by χ2 minimization can be performed with one parameter less than usual by…

Interplay between Detection Strategies and Stochastic Resonance Properties
We discuss how to exploit stochastic resonance with the methods of statistical theory of decisions. To do so, we evaluate two detection strategies: escape time analysis and strobing. For a standard…

Comment on Dimensionless Units in the SI
The recent paper by Mohr and Phillips (arXiv:1409.2794) describes several problems relating to the treatment of angle measurement within SI, the unit hertz, and quantities that can be considered…

A Comparison of Limit Setting Methods for the On-Off Problem
We study the frequentist properties of confidence intervals for the On-Off problem. The methods include all those in common use today. We derive explicit formulas for the limits and calculate the…

Predictability of Critical Transitions
Critical transitions in multistable systems have been discussed as models for a variety of phenomena ranging from the extinctions of species to socio-economic changes and climate transitions between…

The development of an information criterion for Change-Point Analysis
Change-point analysis is a flexible and computationally tractable tool for the analysis of times series data from systems that transition between discrete states and whose observables are corrupted…

Model selection for amplitude analysis
Model complexity in amplitude analyses is often a priori under-constrained since the underlying theory permits a large number of possible amplitudes to contribute to most physical processes. The use…

Search for a Lorentz invariant velocity distribution of a relativistic gas
We examine numerically and analytically the problem of the relativistic velocity distribution in a 1-dim relativistic gas in thermal equilibrium. Our derivation is based on the special theory of…

Patterns for the waiting time in the context of discrete-time stochastic processes
The aim of this study is to extend the scope and applicability of the level-crossing method to discrete-time stochastic processes and generalize it to enable us to study multiple discrete-time…

Integration of in situ Imaging and Chord Length Distribution Measurements for Estimation of Particle Size and Shape
Efficient processing of particulate products across various manufacturing steps requires that particles possess desired attributes such as size and shape. Controlling the particle production process…

Combined estimation for multi-measurements of branching ratio
A maximum likelihood method is used to deal with the combined estimation of multi-measurements of a branching ratio, where each result can be presented as an upper limit. The joint likelihood…
