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…
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…
The Physics of the Dancing \emph{Deity}: Coupled Oscillators in Himalayan Processions
Nalin Dhiman
In parts of Himachal Pradesh (Kullu and Mandi) and the Western Himalaya, village deities (\emph{devtÄ}) are carried through the landscape on shoulder-borne palanquins or ``raths.'…
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…
