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 ...

Statistics in Medicine, Volume 45, Issue 23-24, October 2026.ABSTRACT Large observational datasets, including those derived from electronic health records, are a valuable resource for medical research but are often affected by missingness, measurement error, and misclassification. Two‐phase sampling with generalized raking (GR) estimation is an efficient and robust approach to statistical inference in such ...

Earth and Space Science, Volume 13, Issue 10, October 2026.Abstract High‐resolution precipitation fields are essential for characterizing climate extremes, assessing sectoral impacts, and improving early warning systems. However, the resolution of global Earth system models (ESMs) and numerical weather prediction (NWP) systems remains limited by computational constraints.

On the group rings of Abelian minimax groups [PDF]
, 2002 An abelian group G is called minimax if it contains a finitely generated subgroup H such that G/H satisfies the minimal condition for subgroups (which I shall abbreviate to min).

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.

A conversation with James V. Zidek
Canadian Journal of Statistics, Volume 54, Issue 3, September 2026.Abstract This article documents a series of exchanges between the authors and the senior Canadian statistician Jim Zidek in early 2026. The interview traces his life trajectory, surveying his principal contributions to statistics while offering insights into his motivations, successes, and challenges.

Equivalent Results in Minimax Theory [PDF]
In this paper we review known minimax results with applications ingame theory and show that these results are easy consequences of thefirst minimax result for a two person zero sum game with finite strategysets published by von Neumann in 1928: Among ...

'Symbol ratio minimax sequences in the lexicographic order' [PDF]
, 2015 Consider the space of sequences of letters ordered lexicographically. We study the set of all maximal sequences for which the asymptotic proportions of the letters are prescribed, where a sequence is said to be maximal if it is at least as great as ...

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.

Image Analysis and StereologyThe acquisition and transmission of magnetic resonance images are susceptible to noise, particularly impulse noise. Although the method based on the ℓ0-norm and overlapping group sparse total variation (ℓ0-OGSTV) is effective for impulse noise image ...
