VERTICAL DIFFERENTIATION AND THE DISTRIBUTION OF INCOME

Bulletin of Economic Research, 2006
The paper analyses the effects of income concentration on the behaviour of a duopoly with vertical product differentiation and uncovered market. By using a trapezoid distribution, we solve explicitly for market equilibrium as a function of a mean preserving spread of the income distribution. We show that overall more concentrated incomes imply stronger

Salt stress-induced seedling growth inhibition coincides with differential distribution of serotonin and melatonin in sunflower seedling roots and cotyledons.

Physiologia Plantarum : An International Journal for Plant Biology, 2014
Indoleamines regulate a variety of physiological functions during the growth, morphogenesis and stress-induced responses in plants. Present investigations report the effect of NaCl stress on endogenous serotonin and melatonin accumulation and their ...

Differential distribution of diatoms and dinoflagellates in a cyclonic eddy confined in the Bay of La Paz, Gulf of California

, 2014
The differential distribution of diatoms and dinoflagellates in the Bay of La Paz, Gulf of California, Mexico, was analyzed in summer of 2009, when a cyclonic eddy confined in the bay dominated the circulation.

Differentiation of Distributions

2010
If f is continuously differentiable on an open set X in R n, one obtains by means of integration by parts that for every test function \(\phi\) the following holds: \(({\rm{test}}\ \partial _j\ f)(\phi ) = - ({\rm {test}}\ f)(\partial _j\ \phi ).\)

Differentially Private Distributed Learning

INFORMS Journal on Computing, 2020
The rich data used to train learning models increasingly tend to be distributed and private. It is important to efficiently perform learning tasks without compromising individual users’ privacy even considering untrusted learning applications and, furthermore, understand how privacy-preservation mechanisms impact the learning process.

Differentiating aggregate gaze distributions

Proceedings of the ACM SIGGRAPH Symposium on Applied Perception in Graphics and Visualization, 2011
A machine learning approach used to classify aggregate gaze distributions recorded by an eye tracker and visualized as heatmaps is demonstrated to successfully discriminate between free and task-driven exploration of video clips.

On distributed order integrator/differentiator

Signal Processing, 2011
In this paper, we derive the impulse response of the distributed order integrator/differentiator and its asymptotic property by using the complex path integral. Based on the derived analytical impulse response, we present a technique to perform the discretization of the above distributed order integrator/differentiator.

DIFFERENTIAL PRIVACY IN DISTRIBUTED SETTINGS

2022
Data is considered the "new oil" in the information society and digital economy. While many commercial activities and government decisions are based on data, the public raises more concerns about privacy leakage when their private data are collected and used.
