Observational and Critical State Physics Descriptions of Long-Range Flow Structures
Using Fracture Seismic methods to map fluid-conducting fracture zones makes it important to understand fracture connectivity over distances greater 10−20 m in the Earth’s upper crust.

A Framework for Analysis and Prediction of Operational Risk Stress
A model for financial stress testing and stability analysis is presented. Given operational risk loss data within a time window, short-term projections are made using Loess fits to sequences of lognormal parameters.

On the three-spliced Exponential-Lognormal-Pareto distribution
To model statistical data coming from two di erent distributions, Cooray and Ananda [1] introduced a composite (two-spliced) Lognormal-Pareto model, that was further extended by Scollnik [9] and fitted to insurance data.

The Poisson-lognormal model as a versatile framework for the joint analysis of species abundances
Joint Species Abundance Models (JSDM) provide a general multivariate framework to study the joint abundances of all species from a community. JSDM account for both structuring factors (environmental characteristics or gradients, such as habitat type or ...

Call center service times are lognormal: A Fokker–Planck description [PDF]
Call centers are service networks in which agents provide telephone-based services. An important part of call center operations is represented by service durations.

BRAQUE: Bayesian Reduction for Amplified Quantization in UMAP Embedding
Single-cell biology has revolutionized the way we understand biological processes. In this paper, we provide a more tailored approach to clustering and analyzing spatial single-cell data coming from immunofluorescence imaging techniques.

Modeling income distribution: An econophysics approach
This study aims to develop appropriate models for income distribution in Iran using the econophysics approach for the 2006–2018 period. For this purpose, the three improved distributions of the Pareto, Lognormal, and Gibbs-Boltzmann distributions are ...

Lognormal Lorenz and normal receiver operating characteristic curves as mirror images [PDF]
The Lorenz curve for assessing economic inequality depicts the relation between two cumulative distribution functions (CDFs), one for the distribution of incomes or wealth and the other for their first-moment distribution.
