Assessing Economic Inequality Through the Lorenz Curve in Central and Eastern European Countries [PDF]

Ovidius University Annals: Economic Sciences Series
This study analyses economic inequality in Central and Eastern Europe (CEE) using tools such as the Lorenz Curve and the Gini coefficient. Originating in 1905, the Lorenz Curve, conceptualized by Max O.

A new geostatistical tool for the analysis of the geographical variability of the indoor radon activity

Nukleonika, 2020
The population is continuously exposed to a background level of ionizing radiation due to the natural radioactivity and, in particular, with radon (222Rn).

Graphical Measures Summarizing the Inequality of Income of Two Groups

Statistics and Public Policy, 2022
Recently, Gastwirth proposed two transformations and of the Lorenz curve, which calculates the proportion of a population, cumulated from the poorest or middle, respectively, needed to have the same amount of income as top .

Introduction to measures of inequality and concentration in tourism [PDF]

, 2016
There are many statistical measures available in the literature for the analysis of inequality and concentration. The most common measure in this field is the Gini index (Roselló Nadal et al.,2004), which is associated to the Lorenz curve.

Active Learning‐Guided Accelerated Discovery of Ultra‐Efficient High‐Entropy Thermoelectrics

Advanced Materials, EarlyView.
An active learning framework is introduced for the accelerated discovery of high‐entropy chalcogenides with superior thermoelectric performance. Only 80 targeted syntheses, selected from 16206 possible combinations, led to three high‐performance compositions, demonstrating the remarkable efficiency of data‐driven guidance in experimental materials ...

Brazil’s Daily Precipitation Concentration Index (CI) Using Alternative Fitting Equation and Ensemble Data

Hydrology
In recent years, precipitation concentration indices have become popular, and the daily precipitation concentration index has been widely used worldwide. This index is based on the Lorenz curve fitting.

The Advantages of Using Group Means in Estimating the Lorenz Curve and Gini Index From Grouped Data

, 2016
A recent article proposed a histogram-based method for estimating the Lorenz curve and Gini index from grouped data that did not use the group means reported by government agencies.

Reduced Switching Threshold and Photo‐Modulated Dynamics in Self‐Organized Hybrid Ag/pV3D3 Nanoparticle Networks: Toward Photoresponsivity in Neural‐Like Networks

Advanced Materials Interfaces, EarlyView.
Self‐organized silver nanoparticle networks coated with poly(1,3,5‐trivinyl‐1,3,5‐trimethyl‐cyclosiloxane) via initiated chemical vapor deposition exhibit a markedly reduced switching threshold (0.5 V vs 3 V). Time‐series analysis reveals that visible‐light illumination modulates the resistive switching activity, with blue light showing pronounced ...

Mucosa‐Interfacing Capsule for In Situ Sensing the Elasticity of Biological Tissues

Advanced Materials Technologies, Volume 10, Issue 6, March 18, 2025.
A fundamental mechanism of palpating soft materials is reported to sense deep tissue elasticity in situ with minimal invasion using the interaction between the robot palpation unit and soft tissues. Both the robot locomotion and elasticity sensing functions are remotely controlled by external magnetic fields, while the sensing data are wirelessly ...
