Statistics in Medicine, Volume 45, Issue 1-2, January 2026.ABSTRACT Derived variables are variables that are constructed from one or more source variables through established mathematical operations or algorithms. For example, body mass index (BMI) is a derived variable constructed from two source variables: weight and height.

Representation Growth of Linear Groups
, 2008 Let $\Gamma$ be a group and $r_n(\Gamma)$ the number of its $n$-dimensional irreducible complex representations. We define and study the associated representation zeta function $\calz_\Gamma(s) = \suml^\infty_{n=1} r_n(\Gamma)n^{-s}$. When $\Gamma$ is an

A Novel Model‐Free Defense Scheme for Power Systems Stability Under Cyber Attacks
IET Generation, Transmission &Distribution, Volume 20, Issue 1, January/December 2026.This paper studies the load frequency control performance of Kundur's 4‐unit‐12‐bus power system under the frequency signal manipulated by false data injection attacks. In this regard, a model‐free resilient defence strategy, comprising a model‐free detection scheme and an event‐triggered mechanism, is proposed to encounter these attacks.

The Intersection of Two Fermat Hypersurfaces in P^3 via Computation of Quotient Curves [PDF]
, 2010 We study the intersection of two particular Fermat hypersurfaces in $\mathbb{P}^3$ over a finite field. Using the Kani-Rosen decomposition we study arithmetic properties of this curve in terms of its quotients.

IET Image Processing, Volume 20, Issue 1, January/December 2026.This paper presents a robust reversible watermarking algorithm based on Chebyshev moments, employing a two‐stage embedding mechanism. The proposed method leverages image block partitioning to embed the copyright watermark and the reversible watermark into non‐overlapping regions located inside and outside the inscribed circle of the image, respectively.

, 2015 We derive new results about properties of the Witten zeta function associated with the group SU(3), and use them to prove an asymptotic formula for the number of n-dimensional representations of SU(3) counted up to equivalence.

On pooling‐based track fusion strategies: Harmonic mean density
IET Radar, Sonar &Navigation, Volume 20, Issue 1, January/December 2026.Pooling strategies are viable techniques for distributed fusion since they do not require ‘extra’ information from local nodes. Harmonic mean density fusion is an attractive method among pooling strategies as it can fuse both Gaussian and Gaussian mixture densities easily.

Long‐Run Convergence Trends in the Association of Southeast Asian Nations
Economics of Transition and Institutional Change, Volume 34, Issue 1, Page 101-115, January 2026.ABSTRACT This paper examines income convergence among the ten‐member Association of Southeast Asian Nations (ASEAN) for the period 1970–2019, spanning the establishment of the ASEAN Economic Community (AEC) in 2015. We employ the novel log t test developed by Phillips and Sul which is robust to heterogeneity and nonlinearity in the data.

Plank theorems and their applications: A survey
Bulletin of the London Mathematical Society, Volume 58, Issue 1, January 2026.Abstract Plank problems concern the covering of convex bodies by planks in Euclidean space and are related to famous open problems in convex geometry. In this survey, we introduce plank problems and present surprising applications of plank theorems in various areas of mathematics.

Siegel–Veech constants for cyclic covers of generic translation surfaces
Journal of the London Mathematical Society, Volume 113, Issue 1, January 2026.Abstract We compute the asymptotic number of cylinders, weighted by their area to any nonnegative power, on any cyclic branched cover of any generic translation surface in any stratum. Our formulae depend only on topological invariants of the cover and number‐theoretic properties of the degree: in particular, the ratio of the related Siegel–Veech ...
