    Key Findings: This paper formalizes Execution-Time Authorization (ETA) as a deterministic runtime enforcement architecture for AI agents, which evaluates proposed actions against policy before real-world effects, emitting a tamper-evident authorization artifact. It establishes the Authorization Boundary Integrity Model (ABIM), defining Output, Input, and Replay Integrity as crucial for conforming ETA deployments, distinguishing it from general guardrails by requiring non-bypassability and fail-closed behavior across covered effect-producing paths. The framework is explicitly aligned with the FERZ instrument set, including the Authorization Artifact Test v1.2 and the Five Tests Standard (5TS) v1.2.0, providing a robust, auditable basis for AI agent governance.

  • Interprofessional identity development: awareness as the beginning of change (Impact: 1.0, Citations: 3)

    Key Findings: The study developed and validated the Awareness of Interprofessional Learning Scale (AIPLS) through exploratory and confirmatory factor analysis, demonstrating excellent model fit (SRMR=.018, RMSEA=.068) and high internal consistency (omega = .81). It found that the existing Readiness for Interprofessional Learning Scale (RIPLS) was not a valid multidimensional instrument due to subscale overlap. Interprofessional awareness, as measured by AIPLS, is proposed as a vital initial stage for developing readiness, self-efficacy, openness, and commitment in interprofessional education.

  • STcompare: comparative spatial transcriptomics data analysis of structurally matched tissues to characterize differentially spatially patterned genes (Impact: 1.0, Citations: 2)

    Key Findings: Introduces STcompare, a statistical framework for comparative spatial transcriptomics that identifies differentially spatially patterned genes between conditions, a capability lacking in prior methods. Through simulations, STcompare provided distinct insights compared to bulk and spatially variable gene expression analyses, robustly controlling for false positives. Its application to mouse kidneys with acute kidney injury revealed tissue compartment-specific molecular dysregulation, and the framework is available as an open-source R package.

  • Mitophagy Facilitates Cytosolic Proteostasis to Preserve Cardiac Function (Impact: 1.0, Citations: 1)

    Key Findings: Demonstrates that cardiomyocyte-specific TRAF2 ablation, impairing mitophagy, leads to accumulation of mitochondrial and cytosolic protein aggregates, including mis-localization of DESMIN. The study showed that mitochondria can take up cardiomyopathy-associated aggregate-prone cytosolic chaperone proteins (R120G CRYAB, P209L BAG3). Crucially, AAV9-mediated TRAF2 transduction in R120G-TG mice reduced mortality, attenuated left ventricular systolic dysfunction, and decreased protein aggregates, highlighting mitophagy's role in ameliorating proteotoxic cardiomyopathy.

  • Meta-domain adaptive framework for efficient diagnostic assessment of lung infection using CT radiographs (Impact: 1.0, Citations: 0)

    Key Findings: The Meta-Domain Adaptive Segmentation Network (MDA-SN) achieved 75.93% Dice index and 67.42% Intersection over Union for lung infection detection, outperforming state-of-the-art methods by 3.32% and 3.28% respectively across datasets. It demonstrates real-time execution, processing 29 CT slices/second with 70% fewer training parameters than competitors, and provides diagnostic assessment by quantifying infection ratios and retrieving relevant CT slices to aid medical experts.

  • Cheminformatic identification of small molecules targeting acute myeloid leukemia (Impact: 1.0, Citations: 0)

    Key Findings: A cheminformatic screen of ~4.2 million compounds identified small molecules selectively killing AML cells by inducing apoptosis, activating autophagy, and compromising glutathione metabolism via glutathione reductase inhibition. These compounds consistently increased cytosolic/mitochondrial reactive oxygen species and reduced ATP synthesis, with strong synergy observed with existing AML treatments like midostaurin and venetoclax. The findings were validated in AML-patient-derived primary cells, affirming their clinical relevance.

  • PyCFRL: A Python library for counterfactually fair offline reinforcement learning via sequential data preprocessing (Impact: 1.0, Citations: 0)

    Key Findings: PyCFRL is a new Python library designed to ensure counterfactual fairness in offline Reinforcement Learning through a novel data preprocessing algorithm. It provides tools for learning and evaluating counterfactually fair RL policies, addressing the issue of RL inadvertently disadvantaging minority groups, and is publicly available on PyPI and GitHub with detailed tutorials.

  • Social robots and future crime: a scoping literature review (Impact: 1.0, Citations: 0)

    Key Findings: This review identified 18 distinct crime threats (e.g., fraud, espionage, abuse towards robots) and 17 countermeasures (e.g., robot rights, technological adaptations) related to social robots across 388 articles. It highlights the broad range of risks and encourages proactive stakeholder engagement, while noting open questions regarding robot rights, liability, and situational crime prevention in cyber-physical spaces.

  • Incident psoriasis in atopic dermatitis: a large-scale cohort study of disease- and treatment-associated risks (Impact: 1.0, Citations: 0)

    Key Findings: Atopic dermatitis (AD) was strongly associated with an increased risk of incident psoriasis (HR 3.81, 95% CI 3.35-4.34) in a large-scale cohort of ~300,000 propensity score–matched pairs. Biologic treatment for AD, however, significantly reduced this risk (HR 0.20, 95% CI 0.11–0.35) compared to conventional systemic immunosuppressants, challenging prior assumptions that biologics unmask psoriasis. The study, using electronic health records, suggests biologics are a safer option regarding psoriasis risk for AD patients requiring systemic treatment.
