Improved Subsynchronous Oscillation Parameter Identification with Synchrophasor Based on Matrix Pencil Method in Power Systems

Journal of Modern Power Systems and Clean Energy
The subsynchronous oscillations (SSOs) related to renewable generation seriously affect the stability and safety of the power systems. To realize the dynamic monitoring of SSOs by utilizing the high computational efficiency and noise-resilient features ...

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.

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.

Researching Children's Literature Otherwise to Decolonise Childhoods in Experimental Curriculum

European Journal of Education, Volume 61, Issue 3, September 2026.
ABSTRACT This article explores children's literature as a tool for decolonising childhood and curriculum through experimental reading practices. Based on post‐qualitative enquiry, and grounded in decolonial, feminist, and posthumanist theories, the study analyses two reading encounters with children using picturebooks from Global South.
