The Inka Khipu and Yupana : A Reply to Zen Vasconcellos and Rojas Gamarra (2026)

ABSTRACT A new analysis by Zen Vasconcellos and Rojas Gamarra offers a novel interpretation of the Inka devices used for calculating ( yupana ) and recording ( khipu ) numbers. They claim the Inka devices represented numbers neither positionally , with place value, as most resear...

Bridging policy and implementation science: operationalising political and structural determinants for health policy implementation evaluation

Abstract Background Despite their critical role in shaping public health policy implementation, key political and structural determinants within implementation frameworks are often poorly defined, underreported, or treated as background rather than as core implementation variable...

Therapeutic Horseback Riding for Youth With Autism and Psychiatric Comorbidities: A Randomized Trial

OBJECTIVE: Autism spectrum disorder care is often complicated by co-occurring psychiatric symptoms. Equine-assisted services show promise for improving behavioral outcomes in this population. We aimed to examine benefits of equine-assisted services for youth with autism at higher...

Applying an adaptationist framework to personality science: jealousy as a mechanistic basis of Emotionality

Over the past half century, the field of personality psychology has developed several descriptive taxonomies, but progress toward a genuinely explanatory framework for between- and within-person variation in psychology and behavior has been elusive. We argue that this is largely...

Deep learning statistical defect models on magnetic material dynamic and static properties

The modelling of realistic magnetic materials requires the inclusion of defects. Based on the pseudospectral Landau-Lifshitz description of magnetisation dynamics, we propose a statistical model that takes into account defects, specifically vacancies. This statistical model can b...

Enhanced molecular diagnosis of Onchocerca lupi using droplet digital PCR in clinically suspected companion animals

Abstract Background Onchocerca lupi , a zoonotic filarial nematode documented in southwestern North America and the Old World, is associated with ocular onchocerciosis in dogs and cats. Clinical signs range from ocular discharge and conjunctivitis to chronic nodular lesions invol...

Semantically-Equivalent Transformations-Based Backdoor Attacks against Neural Code Models: Characterization and Mitigation

Neural code models are increasingly embedded in software development workflows, but their susceptibility to backdoor attacks presents a significant security risk. Existing studies have mainly examined injection-based attacks, which insert anomalous patterns into code and can ofte...

Merits of geometric algebra applied to cryptography and machine learning

Abstract We present Clifford fully homomorphic encryption (FHE), the first ring-learning with errors (RLWE)-based FHE scheme with native support for all Clifford algebra operations, enabling privacy-preserving computation on geometric data. Unlike conventional FHE schemes that fl...

Vibrational Spectraof Anionic Polycyclic AromaticHydrocarbons in the CH Stretching Region: Anthracene, Pyrene, Perylene,and Fluoranthene

Abstract The CH stretching region of the infrared spectra of polycyclic aromatic hydrocarbon radical anions (2700–3100 cm–1) is characterized by complicated band patterns that defy straightforward assignments from harmonic calculations. We compare experimental infrared photodisso...

Engineered Deoxyribonucleic Acid-Tunable Spheroid Platform for Analysis of Tumor-Macrophage Interactions

Abstract Tumor architecture strongly influences immune cell behavior, yet the individual contributions of cell-cell spacing and hypoxia remain difficult to isolate in vivo. Here, we use a DNA-programmable 3D tumor spheroid platform to generate 4T1 spheroids with tunable intercell...

Which combinations of behaviour change techniques work best? Evidence from meta-review of interventions addressing healthy diet and exercise after breast cancer

Abstract Background The primary aim was to identify combinations including ≥ 3 behavior change techniques (BCTs) that are jointly used in behavioral interventions for women with/survivors of breast cancer, and result in a simultaneous improvement of physical activity, healthy nut...

Following a Fatal Campus Shooting, Coping Self-Efficacy and Coping Styles Interact to Predict Posttraumatic Growth

Gun violence in U.S. academic settings has increased in recent years, posing significant psychological and social challenges for affected communities. In the aftermath of a campus shooting, community members employ a range of coping strategies to manage their distress; decisions...

Learning from the Bowl in My Living Room: A Phenomenology of Openness in the Age of Artificial Intelligence

Contemporary artificial intelligence systems present themselves through the aesthetic of openness: a clean interface, a blinking cursor, an implicit invitation to bring whatever one wishes. This essay argues that this appearance conceals a structural inversion. Drawing on phenome...
