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...
