Dominance properties of constrained Bayes and empirical Bayes estimators
, 2013 This paper studies decision theoretic properties of benchmarked estimators which are of some importance in small area estimation problems. Benchmarking is intended to improve certain aggregate properties (such as study-wide averages) when model based ...

Movement Disorders, Volume 41, Issue 1, Page 190-199, January 2026.Abstract Background Disease‐modifying treatments are a critical unmet need in Parkinson's disease (PD). Phase 2 futility trials using the Simon two‐stage design offer an efficient strategy to evaluate candidate treatments in an early PD population. Objective The aim was to assess the feasibility of Simon two‐stage futility trials in early, levodopa ...

A Geometric Approach to Group Delay Network Synthesis [PDF]
Radioengineering, 2016 All-pass networks with prescribed group delay are used for analog signal processing and equalisation of transmission channels. The state-of-the-art methods for synthesising quasi-arbitrary group delay functions using all-pass elements lack a theoretical ...

Model Assisted Variable Clustering: Minimax-optimal Recovery and Algorithms [PDF]
, 2018 Model-based clustering defines population level clusters relative to a model that embeds notions of similarity. Algorithms tailored to such models yield estimated clusters with a clear statistical interpretation.

Sparse additive regression on a regular lattice
, 2014 We consider estimation in a sparse additive regression model with the design points on a regular lattice. We establish the minimax convergence rates over Sobolev classes and propose a Fourier-based rate-optimal estimator which is adaptive to the unknown ...

The GJMS operators in geometry, analysis and physics
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract The GJMS operators, introduced by Graham, Jenne, Mason and Sparling, are a family of conformally invariant linear differential operators with leading term a power of the Laplacian. These operators and their method of construction have had a major impact in geometry, analysis and physics.

Semilinear elliptic problems on unbounded subsets of the Heisenberg group
Electronic Journal of Differential Equations, 2001 In this paper we discuss the applications of an abstract version of concentration compactness to minimax problems. In particular, we prove the existence of solutions to semilinear elliptic problems on unbounded subsets of the Heisenberg group.

Existence of two nontrivial solutions for semilinear elliptic problems
Electronic Journal of Differential Equations, 2006 This paper concerns the existence of multiple nontrivial solutions for some nonlinear problems. The first nontrivial solution is found using a minimax method, and the second by computing the Leray-Schauder index and the critical group near 0.
