Below are the latest papers in physics and data analysis, organized for easy reading and discovery.
This paper reviews recent advancements in pattern recognition and data analysis for Ring Imaging Cherenkov (RICH) detectors, covering improvements in traditional reconstruction methods, the integration of modern machine learning, and emerging trends like global particle identification and generative models for simulation.
This study presents globally inverted pressure-temperature phase diagrams for Fe, MgO, SiO2, and MgSiO3 up to 5,000 GPa, derived from machine learning and experimental data, which resolve long-standing disputes regarding their melting curves and refine internal structure models for giant and super-Earth exoplanets.
This paper introduces a robust information-theoretic framework based on predictability gain to quantify temporal memory in discrete stochastic processes, demonstrating its superiority over traditional criteria and revealing that daily precipitation in the contiguous United States is well-described by low-order Markov chains with distinct regional and seasonal variations.
This paper introduces Ion Count-Aided Microscopy (ICAM), a quantitative imaging technique that statistically estimates secondary electron yield to substantially reduce shot noise and enable high-quality, low-dose imaging of fragile nanoscale samples.
This paper introduces a maximum-entropy framework for continuous-time temporal networks that factorizes interactions into global time processes and static edge probabilities, enabling closed-form analytical solutions and improved generative modeling via non-homogeneous Poisson processes.
This study introduces a computationally efficient framework that utilizes non-interacting electron density and Bayesian active learning to achieve highly accurate, zero-shot extrapolative predictions of alloy properties across vast compositional landscapes, significantly reducing the data requirements for discovering refractory high-entropy alloys.
This paper identifies a novel mechanism called "pseudo-coherence," where non-normal pseudospectral amplification in linearly stable, non-oscillatory stochastic systems drives a sharp transition to intermittent collective temporal organization and irreversible currents without requiring intrinsic oscillators or dynamical instabilities.
This paper introduces two interpretable symbolic machine learning methods, the Symbolic Neural Forecaster (SyNF) and the Symbolic Tree Forecaster (SyTF), which successfully learn explicit algebraic equations to forecast chaotic time series with accuracy competitive to deep learning while providing transparent insights into the underlying dynamics.
This paper introduces Partial Decomposition of Granger Causality (PDGC), a novel framework leveraging Partial Information Decomposition to dissect multivariate spectral Granger causality into unique, redundant, and synergistic components, which was successfully applied to physiological networks to reveal distinct patterns of autonomic dysfunction in patients prone to neurally-mediated syncope.
This paper proposes a scalable Heterogeneous Graph Neural Network (HGNN) that employs a multi-task learning paradigm to simultaneously perform particle vertex association and graph pruning, thereby significantly improving beauty hadron reconstruction performance and inference efficiency for complex particle collision events at the Large Hadron Collider.
