Topological Sensitivity in Connectome-Constrained Neural Networks
Nalin Dhiman
Connectome-constrained neural networks are often evaluated against sparse random controls and then interpreted as evidence that biological graph topology improves learning efficien…
Who Moves the Deity? Mechanics, Participation, and Attributed Agency in Himalayan Rath Carrying
Nalin Dhiman
People carry ritual palanquins, or raths, while describing themselves as following a deity's movement. This study combines western Himalayan ethnography, motor-control research and…
sidmkit: A Reproducible Toolkit for SIDM Phenomenology and Galaxy Rotation-Curve Modeling
Nalin Dhiman
Self-interacting dark matter (SIDM) is a well-motivated extension of cold dark matter that can modify halo structure on galactic and group scales while remaining consistent with la…
FANoS-v2: Feedback-Controlled Momentum with Thermostat Damping for Lightweight Neural Optimization
Nalin Dhiman
\FANOS{} is a PyTorch optimizer that augments RMS-preconditioned momentum with a scalar feedback controller over update energy. The public reference implementation stores momentum…
A Velocity Coupled Radial Acceleration Ansatz for Disk-Galaxy Rotation Curves: Fits to SPARC, Bayesian Inference, and Parameter Identifiability
Nalin Dhiman
Observed rotation curves of disk galaxies remain a sharp empirical probe of the relationship between baryons and dynamics. We study a minimal, explicitly \emph{phenomenological} al…
