From Psychological Need Satisfaction to AI Dependency: The Divergent Roles of Basic and AI-Specific Needs

Examination of the satisfaction of psychological needs relates to AI dependency suggests that generative AI may function not only as a compensatory resource for unmet needs, but also as a primary context for need satisfaction, thereby reinforcing dependency-related patterns of use.

Patient-derived 3D organotypic co-cultures as a long-term ex vivo model for pleomorphic adenoma of the parotid gland

Abstract Pleomorphic adenoma is the most common benign salivary gland tumor and most frequently arises in the parotid gland. Although benign, it can recur and may undergo malignant transformation, underscoring the need for experimental models that preserve native tissue features over time. In this study, fresh tumor ti...

Environmental Information Saturation and Measurement-Induced Stable Localization A Testable Phenomenological Model Based on Effective Mass and Open-System Dynamics

AbstractThis study treats quantum measurement not as a process that must produce an instantaneous ontological collapse, but as an open-system process that spatially narrows a specified measurement record and stabilizes it against subsequent spreading. The proposed phenomenological model combines system-environment mutu...

TorchEBM: A Composable PyTorch Library for Energy-Based and Transport-Based Generative Models

TorchEBM is a PyTorch library for generative models defined either by a scalar potential or by a transport between densities. Energy-based models, diffusion, flow matching, and Schrödinger bridges are factored into one set of composable primitives: energies and fields, interpolants, couplings, training objectives, samp...

Supporting GPR Data for Time-Lapse Imaging of Subsurface Fluid Heterogeneity With Physics-Guided Diffusion-Regularized Full-Waveform Inversion

This dataset provides the supporting ground penetrating radar data used for laboratory and field validation in the study “Time-Lapse GPR Imaging of Subsurface Fluid Heterogeneity With Physics-Guided Diffusion-Regularized Full-Waveform Inversion.” The deposited files contain the data required to support the real data an...

Analytical Solutions of Volterra Integral Equations Involving Jacobi Polynomial Nonlinearities: A Power Series Method

Nonlinear Volterra integral equations model several phenomena in a variety of fields, including epidemiology, population growth theory, diffusion and heat transfer problems. In this paper, the analytical solution of a class of nonlinear Volterra integral equations of the second kind is presented using a power series me...

The Theoretical Floor Rises When You Ask for More ── From an osmotic pressure of 29.7458 bar, the minimum work is 0.9508 kWh/m^3 at 25 per cent recovery and 1.5273 at 75 ── against a plant at 3.0 the ratio is 2.6190, and the floor is a moving target ── [Paper 446]

A theoretical floor is taken to be a fixed target. This paper shows that how much one asks for moves the floor itself──so “how many times the floor” is undetermined without stating the condition. No new theorem or law is claimed. Scope of this paper (scope note): No new theorem or law is claimed──osmotic pressure, the...

AETERNA SELYE ENGINE: A Deterministic Physiological Digital Twin of the Neuroendocrine HPA-Axis, Mitochondrial Allostatic Load, and Epigenetic Aging Dynamics

AETERNA SELYE ENGINE (v1.0.0-SINGULARITY) establishes the first mathematically closed, deterministic and stochastic physiological digital twin of the human neuroendocrine Hypothalamic-Pituitary-Adrenal (HPA) axis and Hans Selye's tripartite General Adaptation Syndrome (Alarm, Resistance, Exhaustion). Coupling continuou...

Neural Codec Resonance: Investigating Zero-Shot Generative Music and Speech Forensics via Multi-Resolution Spectral and Phase Invariances

odels—spanning neural vocoders, latent diffusion architectures,and discrete neural codecs—have enabled the synthesis ofhighly realistic musical pieces and vocal performances. Whiledata-driven classifiers frequently overfit to superficial datasetartifacts, physically grounded methods aim to detect the invariantmathemati...

Auditory nerve phenotypes reveal a myelin-associated subtype of age-related hearing loss

Communication difficulties in older adults are only partially explained by elevated hearing thresholds, suggesting that age-related changes in auditory nerve function contribute to disability beyond conventional measures of hearing sensitivity. Myelin degeneration is increasingly recognized as a fundamental feature of...
