On the regularity of the conditional distribution of the sample mean [PDF]

, 2013
We show that the hypothesis of regularity of the conditional distribution of the empiric average of a finite sample of IID random variables, given all the sample "fluctuations", which appeared in our earlier manuscript |1] in the context of the ...

Moody's Correlated Binomial Default Distributions for Inhomogeneous Portfolios

, 2006
This paper generalizes Moody's correlated binomial default distribution for homogeneous (exchangeable) credit portfolio, which is introduced by Witt, to the case of inhomogeneous portfolios. As inhomogeneous portfolios, we consider two cases.

A conditional space–time POD formalism for intermittent and rare events: example of acoustic bursts in turbulent jets

Journal of Fluid Mechanics, 2018
We present a conditional space–time proper orthogonal decomposition (POD) formulation that is tailored to the eduction of the average, rare or intermittent events from an ensemble of realizations of a fluid process.

Prediction of Structural Stability of Layered Oxide Cathode Materials: Combination of Machine Learning and Ab Initio Thermodynamics

Advanced Energy Materials, EarlyView.
In this work, we developed a phase‐stability predictor by combining machine learning and ab initio thermodynamics approaches, and identified the key factors determining the favorable phase for a given composition. Specifically, a lower TM ionic potential, higher Na content, and higher mixing entropy favor the O3 phase.

Dual Lukacs regressions for non-commutative variables

, 2013
Dual Lukacs type characterizations of random variables in free probability are studied here. First, we develop a freeness property satisfied by Lukacs type transformations of free-Poisson and free-Binomial non-commutative variables which are free. Second,

Quantifying the land‐use change due to soybean‐based biodiesel in the United States

Applied Economic Perspectives and Policy, EarlyView.
Abstract We quantify the impact of soybean oil‐based biodiesel production on US cropland, using a method that accounts for the intermediate effect of soybean crushing facilities. Based on U.S. Environmental Protection Agency data for biodiesel production and proprietary data for soybean crushing facilities over 2011–2020, we find that the elasticities ...

Do Consumers Value Diversity in Agriculture? A Choice Experiment

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT Farm ownership in the US today is racially and ethnically homogeneous. Diverse farmers and ranchers make up less than 10% of all producers, they tend to be less financially stable and have tighter profit margins. In the past few years, both government and industry programs have aimed to increase the participation and profitability of diverse ...

Dollars for Drops: Abatement Cost of Water for Irrigation in the Colorado River Basin

Applied Economic Perspectives and Policy, EarlyView.
ABSTRACT The Colorado River is a lifeline for more than 40 million people in the western United States. However, with climate change diminishing snowpacks in the Rocky Mountains and increasing demands from agriculture and urban areas, the river's flow has become insufficient to meet all the competing needs.

Tracing quantum correlations back to collective interferences

New Journal of Physics
In this paper, we investigate the possibility of explaining nonclassical correlations between two quantum systems in terms of quantum interferences between collective states of the two systems.
