Non-Floquet oscillations of a parametrically driven rigid planar pendulum

This paper identifies a novel type of nonlinear oscillation in a parametrically driven rigid planar pendulum that occurs in regions predicted to be stable by Floquet analysis, characterized by periods longer than twice the driving period and a unique power spectrum where the two dominant response frequencies sum to the driving frequency.

Is K-fold cross validation the best model selection method for Machine Learning?

This paper proposes a novel K-fold CUBV statistical test that combines K-fold cross-validation with Bayesian upper bounds and concentration inequalities to provide a robust criterion for validating machine learning accuracy and detecting effects while avoiding excess false positives, particularly in scenarios with small sample sizes and heterogeneous data.

Beyond Land Surface Temperature: Explainable Spatial Machine Learning Reveals Urban Morphology Effects on Human-Centric Heat Stress

By employing a novel geographically weighted XGBoost and GAM workflow in Singapore, this study demonstrates that land surface temperature (LST) fails to adequately capture human heat stress (UTCI) because it overlooks critical physiological drivers like shading and sky view factor, highlighting the need for more human-centric metrics in climate-adaptive urban planning.

Systemic Risk and Default Cascades in Global Equity Markets: A Network and Tail-Risk Approach Based on the Gai Kapadia Framework

This study extends the Gai-Kapadia interbank contagion framework to global equity markets, revealing that while the overall system exhibits strong resilience to shocks, systemic risk is driven by the interaction between heavy-tailed loss distributions and the high clustering of emerging market subnetworks, which amplifies local propagation despite limited global spread.

Quantum Correlations in Classical Systems

This paper demonstrates that a classical fluid splitter can reproduce quantum-like correlations, including Tsirelson-type Bell violations, by showing that such phenomena arise from ensemble effects on dynamically inseparable entities rather than intrinsic particle properties, thereby challenging conventional interpretations of Local Realism while remaining consistent with the Correspondence Principle.

In situ and operando laboratory X-ray absorption spectroscopy at high temperature and controlled gas atmosphere with a plug-flow fixed-bed cell

This paper demonstrates the capabilities of a custom-built plug-flow fixed-bed cell for high-temperature (up to 1000°C) and high-pressure (up to 10 bar) operando laboratory X-ray absorption spectroscopy, successfully resolving oxidation state changes and catalytic activity in manganese and nickel systems during CO2 methanation within 5–15 minutes per spectrum.

Revisiting the distance and the globular cluster system of the remarkable galaxy UDG1 in the NGC 5846 group

This paper resolves conflicting reports regarding the distance and globular cluster (GC) count of the ultra-diffuse galaxy UDG1 in the NGC 5846 group by establishing a new SBF-based distance that confirms its group membership and demonstrating that, when applying a consistent selection method for brighter GCs, previous studies are actually in agreement regarding a total system of approximately 50 GCs and a massive halo exceeding 1011^{11} M_{\odot}.
