Act as an expert academic designer. Create a highly professional, clean, and visually compelling single-slide scientific poster for a 3-Minute Thesis (3MT) presentation based on the following text. Title: Mathematical Radar for Multi-Strain Epidemics: Navigating the 'Epidemic Seesaw' Author: [Your Name] Structure the slide into 4 logical blocks with clear visual hierarchy: 1. THE PROBLEM (Introduction): Classical SIR models assume single-virus isolation. In reality, multiple strains (Strain A & Strain B) compete for the same host. Cross-immunity creates a dynamic where one strain acts as a biological shield against another. 2. THE METHOD (Mathematical Modeling): A mathematical bridge combining multi-strain epidemiology and nonlinear wave theory (Korteweg–de Vries type equations). Built a Python numerical simulator for a population of 100,000 to track how competing epidemic waves interact over space and time. 3. THE TRAP (Key Finding): "The Epidemic Seesaw". Moderately vaccinating only aggressive Strain A clears the field for Strain B. Strain B's peak is delayed by 70+ days, creating a deceptive illusion of safety before a massive second wave hits. 4. THE SOLUTION (Impact): 95% vaccine efficacy collapses the nonlinear wave structure. Peak hospital load plunges by more than half (from 42,000 down to 20,000 cases). Serves as a mathematical radar for public health. Visual Style Guidelines: - Color palette: Professional clinical colors (e.g., deep navy blue, crisp white, with a sharp accent color like warning orange or red for the "Seesaw" trap). - Layout: 3 or 4 clean columns/blocks. Maximize whitespace. - Visuals: Use icon/diagram placeholders for a "Wave/Seesaw", a "Python Simulation plot", and a "Before/After Hospital Load chart". Minimum text, maximum impact.
