Action Design Research for Actionable Knowledge Production: A Metareflexive Methodology for Digital Transformation and Innovation Studies

open access: yesCreativity and Innovation Management, Volume 35, Issue 2, Page 317-336, June 2026.
ABSTRACT The sociotechnical complexities and hidden dynamics shaping the evolution of digital transformation (DT) and innovation initiatives frequently elude traditional research approaches reliant on retrospective analysis, static and detached observation.

Academic Optimism Profiles and Teachers' Conceptions of Assessment in a High‐Stakes System: A Latent Profile Analysis From Türkiye

open access: yesEuropean Journal of Education, Volume 61, Issue 2, June 2026.
ABSTRACT This study examined how primary teachers' school culture, conceptualised as Academic Optimism (AO), relates to teachers' conceptions of assessment in Türkiye, where Assessment for Learning is promoted within an enduring testing culture. Using a cross‐sectional survey of 558 primary teachers, we validated measurement models for AO and Teachers'

Infinity‐operadic foundations for embedding calculus

open access: yesJournal of Topology, Volume 19, Issue 2, June 2026.
Abstract Motivated by applications to spaces of embeddings and automorphisms of manifolds, we consider a tower of ∞$\infty$‐categories of truncated right modules over a unital ∞$\infty$‐operad O$\mathcal {O}$. We study monoidality and naturality properties of this tower, identify its layers, describe the difference between the towers as O$\mathcal {O}$

Applications of higher harmonic control to hingeless rotor systems [PDF]

open access: yes
A comprehensive analytical formulation was developed to predict the vibratory hub loads of a helicopter rotor system in forward flight. This analysis is used to calculate the optimal higher harmonic control inputs and associated actuator power required ...

Deep‐Seated Landslide Stability on Curved Basal Surfaces With and Without Glacier Buttressing

open access: yesGeophysical Research Letters, Volume 53, Issue 10, 28 May 2026.
Abstract Glacial retreat influences landslide dynamics, yet the controls on stability and transient acceleration remain unclear. We develop a two‐dimensional mechanical model of landslides with curved basal surfaces, Mohr‐Coulomb friction, and ice buttressing.

Glutamine Deprivation Triggers Tribbles Homolog 3 Dependent G‐Quadruplex Resolution to Maintain DNA Repair and Tumor Survival

open access: yesAdvanced Science, Volume 13, Issue 27, 13 May 2026.
Glutamine deprivation triggers transient DNA damage yet activates adaptive repair in hepatocellular carcinoma cells. We identify TRIB3 as a stress‐induced nuclear scaffold that associates with DDX5 and G‐quadruplex DNA atBRCA1 andRAD51AP1 promoters. TRIB3 loss increases G4 accumulation, suppresses HR gene transcription, elevates γ‐H2A.X, and sensitizes

VAE+DDPG: An Attention‐Enhanced Variational Autoencoder for Deep Reinforcement Learning‐Based Autonomous Navigation in Low‐Light Environments

open access: yesAdvanced Intelligent Systems, Volume 8, Issue 5, May 2026.
Variational Autoencoder+Deep Deterministic Policy Gradient addresses low‐light failures of infrared depth sensing for indoor robot navigation. Stage 1 pretrains an attention‐enhanced Variational Autoencoder (Convolutional Block Attention Module+Feature Pyramid Network) to map dark depth frames to a well‐lit reconstruction, yielding a 128‐D latent code ...
