% Abstract
\begin{abstract}
Provide a concise summary (150--250 words) of the purpose, methodology, and main results of the study. Ensure the abstract is self-contained and understandable to mathematically trained readers outside the specific application domain.
\end{abstract}

% ---------- Section 1 ----------
\section{Introduction}
Introduce the problem, its background and significance. Define the main goals and contributions. State clearly what is new, why it matters, and how it is validated or demonstrated.

% ---------- Section 2 (optional) ----------
\section{Conceptual Framework (optional)}
If applicable, explain the underlying concept or domain-specific idea before introducing mathematical models. Provide a concise, accessible explanation targeted at readers with strong mathematics but not domain expertise.

% ---------- Section 3 (optional) ----------
\section{Related Work (optional)}
Place your contribution in context. Summarize key prior work and explain how your approach differs or improves upon existing methods.

% ---------- Section 4 ----------
\section{Mathematical Formulation}
Present the model, assumptions, variables, and parameters clearly. Define all notation on first use. For example, an equation:
\begin{equation}
\label{eq:demo}
\frac{d x(t)}{dt} = f\big(x(t), \theta\big), \qquad x(0) = x_0,
\end{equation}
where $x(t)$ is the state and $\theta$ are model parameters.

% ---------- Section 5 (optional) ----------
\section{Model Validation (optional)}
Describe validation strategy (e.g., analytical benchmarks, empirical datasets, cross-validation, ablation studies). Report error metrics and uncertainty when applicable.

% ---------- Section 6 ----------
\section{Simulation or Computational Method}
Detail numerical methods or algorithms used, including discretization, solvers, tolerances, and implementation notes sufficient for reproduction. Include computational complexity where appropriate.

% ---------- Section 7 ----------
\section{Results and Discussion}
Present tables and figures with interpretable captions. Discuss practical implications, sensitivity to parameters, and limitations.
