Temporally Robust Rainfall Classification from Radiosonde-Derived Atmospheric Instability Indices: A Machine Learning Approach with SHAP Interpretability

We evaluate binary rainfall occurrence classification in southern Thailand using 00 UTC radiosonde profiles from Phuket Airport and rainfall observations at Phuket, Krabi, Takua Pa (Phang-nga) and Nakhon Si Thammarat. Of 2631 soundings from 2011 to 2021, 1487 met quality-control...

Factors associated with inadequate and problematic sexual health literacy among hill tribe junior high school students in northern Thailand

Sexual health literacy (SHL) is an important factor in preventing sexually transmitted infections (STIs) among junior high school students, particularly in middle- to lower-income countries, including Thailand. This study aimed to determine the factors associated with SHL among h...

SGOED: An Atemporal Matrix Formalism for Stability-Gated Crystallization and Aggregation (Phase 1-2)

This record contains the main SGOED manuscript in publication-ready format, together with its two technical appendices. SGOED (Structural Gradient Ontology & Equilibrium Dynamics) is a toy-level mathematical formalism exploring how stable structures emerge from matrix chaos witho...

SGOED Exploratory Notes: STF Connection & K-Analogue Program

TOY-LEVEL EXPLORATORY NOTES - NOT PEER-REVIEWED PHYSICS. This record groups five working notes produced during the SGOED program, covering the conceptual connection between SGOED and the Structural Time Framework (STF), the K-analogue ordering mechanism, the time-vs-order-of-chan...
