Random discrete probability measures based on a negative binomial process

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract A distinctive functional of the Poisson point process is the negative binomial process for which the increments are not independent but are independent conditional on an underlying gamma variable. Using a new point process representation for the negative binomial process, we generalize the Poisson–Kingman distribution and its corresponding ...

On the Dirichlet problem for degenerate monotone operators [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 2003
We prove an existence theorem for the Dirichlet problem in divergence form for degenerate monotone operators (also multivalued) with growth coefficients in BMO. We consider these problems in an open cube of IRn, n ≥ 2, and in Sobolev spaces with exponent

Functional regression with intensively measured longitudinal outcomes: a new lens through data partitioning

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract Modern longitudinal data from wearable devices consist of biological signals at high‐frequency time points. Distributed statistical methods have emerged as a powerful tool to overcome the computational burden of estimation and inference with large data, but methodology for distributed functional regression remains limited.

On manifolds with nonnegative Ricci curvature and the infimum of volume growth order $<2$ [PDF]

open access: yesarXiv
We prove two rigidity theorems for open (complete and noncompact) $n$-manifolds $M$ with nonnegative Ricci curvature and the infimum of volume growth order $<2$. The first theorem asserts that the Riemannian universal cover of $M$ has Euclidean volume growth if and only if $M$ is flat with an $n-1$ dimensional soul.

Growth of normalizing sequences in limit theorems for conservative maps

open access: yesElectronic Communications in Probability, 2018
We consider normalizing sequences that can give rise to nondegenerate limittheorems for Birkhoff sums under the iteration of a conservative map. Mostclassical limit theorems involve normalizing sequences that are polynomial,possibly with an additional slowly varying factor.

Machine Learning–Driven Screening of High‐Activity Antitumor Nanozymes Using an Ensemble Enzymatic Oracle System

open access: yesCancer Nexus, EarlyView.
ABSTRACT Nanozymes, by mimicking the catalytic sites of natural enzymes, have emerged as effective substitutes for traditional natural enzymes. However, the relationship between the physicochemical properties and activity of nanozymes is complex and nonlinear.

First‐order Sobolev spaces, self‐similar energies and energy measures on the Sierpiński carpet

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract For any p∈(1,∞)$p \in (1,\infty)$, we construct p$p$‐energies and the corresponding p$p$‐energy measures on the Sierpiński carpet. A salient feature of our Sobolev space is the self‐similarity of energy. An important motivation for the construction of self‐similar energy and energy measures is to determine whether or not the Ahlfors regular ...

The Serendipity Theorem for an Endogenous Open Economy Growth Model

open access: yesTheoretical Economics Letters, 2018
A Samuelsonian serendipity theorem for an endogenous growth model is derived. The formula for optimal population growth rate deviates from those of the model with exogenous population growth rates in a third best endogenous growth model of the Lucas type with imperfect international capital movements and human capital externalities.
