Reproducibility and positioning sensitivity of CT beam width measurements using a pencil ionization chamber and radiopaque mask

Journal of Applied Clinical Medical Physics, Volume 27, Issue 9, September 2026.
Abstract Purpose To evaluate the reproducibility and precision of CT beam width measurements using a pencil ionization chamber and radiopaque mask and to assess the robustness of the technique against clinically realistic setup errors in the superior‐inferior (SI) and anterior‐posterior (AP) directions. Methods Beam width was measured on a GE Discovery

Language Experience Shapes Creative Idea Generation

The Journal of Creative Behavior, Volume 60, Issue 3, September 2026.
ABSTRACT Bilinguals often outperform monolinguals on creative tasks, suggesting a positive link between bilingualism and creativity. However, the inconsistent definitions of both bilingualism and creativity have made it difficult to understand the precise factors driving the association.

Matrix pencils completion problems II

Linear Algebra and its Applications, 2008
[For part I see the author, ibid. 428, No.~1, 259--304 (2008; Zbl 1131.15010).] The paper deals with the matrix pencils completion problem. This problem analyzes the existence of a matrix pencil with prescribed Kronecker invariants and a regular subpencil. Specifically, the author studies the following problem: Let \(A(\lambda) \in F[\lambda]^{n \times

Multi‐Stakeholder Perspectives on Facilitators and Barriers to Later Morning Start Times for Senior High School Students in Aotearoa New Zealand

Kōtuitui: New Zealand Journal of Social Sciences Online, Volume 21, Issue 3, September 2026.
Later school start times for senior high school students could improve health and wellbeing by better aligning with adolescent sleep biology, which shifts sleep later. This study explored perceived facilitators and barriers to implementing later starts in Aotearoa New Zealand.

VQ‐Wave: A Physics‐Driven Spatiotemporal Deep Learning Approach for Noncontrast‐Enhanced Lung Ventilation and Perfusion MRI

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1427-1442, September 2026.
ABSTRACT Purpose To develop a robust deep learning framework for noncontrast‐enhanced functional lung MRI, overcoming the limitations of spectral decomposition in the presence of physiological nonstationarity. Methods We introduce VQ‐Wave (Ventilation/Q‐perfusion Waveform‐based Assessment of Variable Evolutions), a physics‐driven spatiotemporal ...

Ventilation Imaging of the Lung at 0.55T With Continuous Slice Cycling

Magnetic Resonance in Medicine, Volume 96, Issue 3, Page 1235-1244, September 2026.
ABSTRACT Purpose To propose and evaluate a novel method for pulmonary ventilation imaging, offering considerably improved SNR. Methods A continuous slice cycling (CSC) acquisition scheme is proposed to exclusively capture signal modulations from respiratory motion with increased SNR.

Model Predictive Control of Gas Networks Based on Port‐Hamiltonian Formulations

Proceedings in Applied Mathematics and Mechanics, Volume 26, Issue 3, September 2026.
ABSTRACT To efficiently compute optimal compressor actions in gas networks, we investigate port‐Hamiltonian models consisting of linear and a nonlinear model assumptions. The control actions are derived via adjoint‐based gradients that incorporate the constraints of the underlying optimization problem. We then present results from the implementation of

From parent–teacher collaboration to young children's numeracy skills: An examination of the underlying mechanisms

British Journal of Educational Psychology, Volume 96, Issue 3, Page 1379-1395, September 2026.
Abstract Background Growing evidence shows that parent–teacher collaboration benefits parents and their children. Yet, there is limited understanding of whether and how parent–teacher collaboration contributes to children's early numeracy skills. Aims This study examined whether parent–teacher collaboration is linked to children's early numeracy skills

Discriminant validity and interrelations of conceptual and procedural knowledge in fractions and algebra: Evidence from confirmatory factor analysis

British Journal of Educational Psychology, Volume 96, Issue 3, Page 1396-1418, September 2026.
Abstract Background Conceptual and procedural knowledge are two distinct types of mathematical knowledge. Measuring them with sufficient discriminant validity is challenging because they are typically highly correlated. Prior studies have demonstrated discriminant validity of paper‐and‐pencil measures separately for fractions and algebra.

Intra‐Individual Variability in Children's Self‐Regulation in Kindergarten Classrooms: An Observational Study

Developmental Science, Volume 29, Issue 5, September 2026.
ABSTRACT Children's ability to self‐regulate varies across days and contextual demands. However, the predominant approach in developmental science is to assess self‐regulation at a single timepoint in one context, limiting our understanding of how and why children's self‐regulation skills vary intra‐ and inter‐individually.
