Variable selection via thresholding
Scandinavian Journal of Statistics, EarlyView.Abstract Variable selection comprises an important step in many modern statistical inference procedures. In the regression setting, when estimators cannot shrink irrelevant signals to zero, covariates without relationships to the response often manifest small but nonzero regression coefficients.

Exploring Imprecise Probabilities in Quantum Algorithms with Possibility Theory
PAMM, Volume 26, Issue 1, March 2026.ABSTRACT Quantum computing utilizes the underlying principles of quantum mechanics to perform computations with unmatched performance capabilities. Rather than using classical bits, it operates on qubits, which can exist in superposition and entangled states. This enables the solution of problems that are considered intractable for classical computers.

Quality and Reliability Engineering International, Volume 42, Issue 2, Page 553-564, March 2026.ABSTRACT The foldover technique for screening designs is well‐known to guarantee zero aliasing of the main effect estimators with respect to two‐factor interactions and quadratic effects. It is a key feature of many popular response surface designs, including central composite designs, definitive screening designs, and most orthogonal, minimally ...

Hybrid kernels integrating genomic and multispectral data improve wheat genomic prediction accuracy
The Plant Genome, Volume 19, Issue 1, March 2026.Abstract Genomic selection (GS) is transforming plant breeding by enabling more accurate and efficient identification of superior genotypes. However, its practical implementation remains challenging, as achieving high prediction accuracy is critical for its success. Several factors—including sample size, the degree of relatedness among individuals, and

Cointegrating Polynomial Regressions With Power Law Trends
Journal of Time Series Analysis, Volume 47, Issue 2, Page 331-344, March 2026.ABSTRACT The common practice in cointegrating polynomial regressions (CPRs) often confines nonlinearities in the variable of interest to stochastic trends, thereby overlooking the possibility that they may be caused by deterministic components. As an extension, we propose univariate and multivariate CPRs that incorporate power law deterministic trends.

On the Method of Harmonic Balance for Lumped‐Element Transformer Models
International Journal of Circuit Theory and Applications, Volume 54, Issue 2, Page 625-637, February 2026.The steady‐state solution of a lumped‐element transformer model with a dry friction‐like hysteresis model depicting the magnetic core is of interest. The harmonic balance method efficiently solves this stiff system. We derive the harmonic balance algorithm, enhance it with performance and convergence improvements, and demonstrate its efficiency by ...

On the structural and practical identifiability of multi‐echo BBB‐ASL tracer kinetic models
Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1205-1222, February 2026.Abstract Purpose Tracer kinetic models are used in arterial spin labeling (ASL); however, deciding which model parameters to fix or fit is not always trivial. The identifiability of the resultant system of equations is useful to consider, since it will likely impact parameter uncertainty.

Magnetic Resonance in Medicine, Volume 95, Issue 2, Page 1044-1067, February 2026.Abstract Purpose Lower field strength scanners with large bore size or complex geometries, and scanners with stronger gradient systems experience increased gradient nonlinearity and concomitant fields, each of which causes distortions in EPI. Current correction approaches based on image‐domain interpolation introduce undesirable spatial blurring.
