Structural Characterization of Cardiac Free‐Running Purkinje Fibers Using Inhomogeneous Magnetization Transfer (ihMT): A Proof of Concept MRI‐Histology Approach

NMR in Biomedicine, Volume 39, Issue 6, June 2026.
The cardiac Purkinje network is essential for synchronized ventricular activation but remains difficult to visualize with conventional MRI due to limited structural contrast. This study demonstrates that inhomogeneous magnetization transfer imaging provides enhanced contrast that differentiates free‐running Purkinje fibers, Purkinje‐Myocardial Junction,

Detection of Dark Companions via The Combination of Eclipse Timing Variation, Hipparcos, and/or Gaia Astrometry: The Cases of V Puppis and CY Ari

The Astrophysical Journal
The third body is expected to shape the formation and evolution of close binary systems. In this work, we develop a method to detect and characterize the tertiary companion around eclipsing binaries through the combined analysis of eclipse timing ...

Beyond CUDOS and DECAY: Mapping Research Norms With an Institutional Logics Wheel

European Journal of Education, Volume 61, Issue 2, June 2026.
ABSTRACT The normative landscape of academic research is increasingly fragmented. Classical CUDOS norms and counternorms coexist across profession, market, corporation, state and community logics, yet existing scholarship rarely explains how these norms are patterned, how they interact, or how tensions between them are mediated.

Error Correction Learning of Second Language Verbal Morphology: Associating Imperfect Contingencies in Naturalistic Frequency Distributions

Language Learning, Volume 76, Issue 2, Page 494-527, June 2026.
Abstract We investigate what is learned from exposure to usage in verbal morphology using an error correction mechanism within an associative learning framework. We computationally simulated how second language (L2) learners would respond to naturalistic input of aspectual usage, characterized by “imperfect contingencies,” given two types of ...

Half a Million Binary Stars Identified from the Low-resolution Spectra of LAMOST

The Astrophysical Journal Supplement Series
Binary stars are prevalent yet challenging to detect. We present a novel approach using convolutional neural networks (CNNs) to identify binary stars from low-resolution spectra obtained by the LAMOST survey.

Evaluation of Different Detection and Identification Methods of Intact Tetrahydro‐Methyltestosterone Sulfate Metabolites in Doping Control

Drug Testing and Analysis, Volume 18, Issue 5, Page 678-689, May 2026.
The micro‐scale synthesis of the six out of eight possible tetrahydro‐methyltestosterone sulfate metabolites was performed, and the synthesized materials were used as analytical standards. The analysis of post‐administration sample extracts from methyltestosterone excretion studies against these standards provides further experimental proof for their ...

Telecological Collapse: The Inevitability of Climate Breakdown in the Transmedial Podcast Drama Forest 404

Future Humanities, Volume 4, Issue 1, May 2026.
ABSTRACT This paper presents a close‐hearing analysis of Forest 404, a transmedial audio drama that was released to BBC Sounds in 2019. Despite the drama's eco‐dystopian critique of teleological ‘progress’ narratives (that enable and perpetuate the destruction of the natural world), I argue that the series ultimately propagates a sense of inevitability

The Eclipsing Novalike Cataclysmic Variable CRTS SSS100505 J093417-174421

The Astrophysical Journal
Time-resolved optical photometry, complemented by Transiting Exoplanet Survey Satellite (TESS) data and long-term survey light curves, reveals that the transient object CRTS SSS100505 J093417-174421 is an eclipsing novalike cataclysmic variable of the VY
